Anwar K, Thaller G, Saeed-Zidane M. Genetic Variations in the NRF2 Microsatellite Contribute to the Regulation of Bovine Sperm-Borne Antioxidant Capacity. Cells 2024; 13:1601. [PMID: 39404365 PMCID: PMC11482559 DOI: 10.3390/cells13191601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 08/30/2024] [Accepted: 09/18/2024] [Indexed: 10/19/2024] Open
Abstract
Nuclear factor (erythroid-derived 2)-like 2 (NRF2) is a transcription factor protein-coding gene, considered a master regulator of the cellular stress response. The genetic variations of the NRF2 could influence its transcriptional profile and, subsequently, the stress resilience in all cell types, including sperm cells. Therefore, the sperm-borne antioxidants abundance in association with the genetic variation of a GCC microsatellite located at the 5' upstream region of the NRF2 gene was investigated in young (n = 8) and old (n = 8) Holstein bulls' sperm cells at different seasons. The sperm DNA was sequenced using Sanger sequencing, while- the sperm-borne mRNA analysis was carried out using the synthesized cDNA and qPCR. The data were statistically analyzed using GraphPad Prism 10.0.2 software. The results showed that two bulls had a heterozygous genotype of eight and nine GCC repeats, while biallelic of eight, nine, and fifteen repeats were identified in two, ten, and two bulls, respectively. The computational in silico analysis revealed that the NRF2 upstream sequence with 15, 9, and 8 GCC repeats bound with 725, 709, and 707 DNA-binding transcription factor proteins, respectively. Lower quality of sperm DNA was detected in the spring season compared to other seasons and in young bulls compared to old ones, particularly in the summer and autumn seasons. The mRNA expression analysis revealed that the PRDX1 gene was the abundant transcript among the studied sperm-borne antioxidants and was significantly determined in old bulls' spermatozoa. Moreover, two transcripts of the NRF2 gene and antioxidant (SOD1, CAT, GPX1, TXN1, NQO1) genes displayed differential expression patterns between the age groups across seasons in an antioxidant-dependent manner. The bulls with a heterozygous GCC sequence exhibited elevated sperm-borne mRNA levels of NRF2 and PRDX1 transcripts. Taken together, the findings suggest that the NRF2-GCC microsatellite may contribute to the transcription regulation of NRF2 transcripts and their subsequent downstream antioxidants in bovine sperm cells.

Liu X, Cao G, Qiu K, Dong Y, Hu C. Lactobacillus plantarum Decreased Ammonia Emissions through Modulating Cecal Microbiotain Broilers Challenged with Ammonia. Animals (Basel) 2023; 13:2739. [PMID: 37685002 PMCID: PMC10487022 DOI: 10.3390/ani13172739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 08/09/2023] [Accepted: 08/10/2023] [Indexed: 09/10/2023] Open
Abstract
Probiotic supplementation has become a prominent method of decreasing ammonia emissions in poultry production. The present study was conducted to investigate the influence of Lactobacillus plantarum on ammonia emission, immune responses, antioxidant capacity, cecal microflora and short chain fatty acids, and serum metabolites in broilers challenged with ammonia. A total of 360 1-day-old yellow-feathered broilers were randomly divided into three treatment groups: birds fed with a basal diet (CON), a basal diet supplemented with ammonia (AN), and a basal diet supplemented with 2.5 × 108 CFU L. plantarum kg-1 and challenged with ammonia (LP). Data showed that L. plantarum supplementation decreased ammonia more than 30% from day 48, and significantly reduced the levels of serum urea nitrogen and ammonia, fecal urease, and ammonium nitrogen compared with those on CON. Compared with AN and CON treatments, LP administration increased (p < 0.05) the concentration of serum immunoglobulin Y (IgY), IgM, and IL-10, as well as the serum total-antioxidant capacity (T-AOC) and GSH-Px, and decreased (p < 0.05) IL-1β, IL-6, and TNF-α. Furthermore, birds supplemented with LP had higher (p < 0.05) cecal contents of short chain fatty acids (SCFAs) than AN birds and had more butyrate than CON birds. Data from 16s high throughput sequencing showed that LP supplementation significantly increased (p < 0.05) the Shannon and Simpson indices of bird cecal microflora, and Alloprevotella dominated the LP birds. The function prediction of cecal microflora indicated that LP treatment significantly increased alanine aspartate and glutamate metabolism, starch and sucrose metabolism, exosome, mismatch repair, homologous recombination, DNA repair and recombination proteins, and amino acid-related enzymes. The serum metabolome showed that LP supplementation significantly changed the aminoacyl-tRNA, pantothenate and acetyl-coenzyme A, arginine, phenylalanine, tyrosine and tryptophan, valine, leucine, and isoleucine biosynthesis; purine, beta-alanine, galactose, histidine, alanine, aspartate and glutamate, glyoxylate and dicarboxylate, pyruvate and thiamine metabolism, melanogenesis, and citrate cycle.

Sperm Quality Affected by Naturally Occurring Chemical Elements in Bull Seminal Plasma. Antioxidants (Basel) 2022; 11:antiox11091796. [PMID: 36139870 PMCID: PMC9495912 DOI: 10.3390/antiox11091796] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 09/07/2022] [Accepted: 09/09/2022] [Indexed: 11/16/2022] Open
Abstract
This study monitored the chemical and biochemical composition of bovine seminal plasma (SP). Freshly ejaculated semen (n = 20) was aliquoted into two parts. The first aliquot was immediately assessed to determine the sperm motion parameters. Another motility measurement was performed following an hour-long co-incubation of spermatozoa with SP at 6 °C. The other aliquot was processed to obtain the SP. Seminal plasma underwent the analyses of chemical composition and quantification of selected proteins, lipids and RedOx markers. Determined concentrations of observed parameters served as input data to correlation analyses where associations between micro and macro elements and RedOx markers were observed. Significant correlations of total oxidant status were found with the content of Cu and Mg. Further significant correlations of glutathione peroxidase were detected in relation to Fe and Hg. Furthermore, associations of chemical elements and RedOx markers and spermatozoa quality parameters were monitored. The most notable correlations indicate beneficial effects of seminal Fe on motility and Mg on velocity and viability of spermatozoa. On the contrary, negative correlations were registered between Zn and sperm velocity and seminal cholesterol content and motility. Our findings imply that seminal plasma has a prospective to be developed as the potential biomarker of bull reproductive health.

Abstract
The study was conducted on a commercial pig farm located in Serbia. Thirty Duroc or Landrace breed boars were randomly selected for this study. The experimental group was fed a compound feed with added organic selenium and Oxynat 3D. The antioxidant status parameters of boar seminal plasma were evaluated using a biochemical analyzer and commercial Randox kits. The sperm chromatin structure assay (SCSA) using flow cytometry (FC) provided information about spermatozoa’s DNA status. Additionally, the total number of motile spermatozoa and spermatozoa kinematic parameters were measured using the computer-assisted sperm analysis (CASA) system. The aim of this study was to improve the parameters of semen by combining two preparations that have a potential antioxidant effect, but also to establish the level of various antioxidant enzymes in native sperm. There was no statistically significant difference in total antioxidant capacity and glutathione peroxidase activity in the seminal plasma obtained from the experimental and control groups of boars. Regarding the superoxide dismutase activity, the research results showed a difference in the control group compared to the experimental one. Moreover, spermatozoa DNA fragmentation and the total number of motile spermatozoa showed statistically significant lower and higher values, respectively, in experimental compared to the control groups. The combination of these two preparations shows significantly enhanced vital parameters of semen. To the best of our knowledge, this study is the first in which the ejaculate parameters were examined after the application of a combination of these two antioxidant supplements.

Abstract
Cryopreservation of sperm is a routine technology in many livestock species, but not in swine. Frozen sperm must result in acceptable conception rates and produce 11-12 piglets/litter to be competitive with traditional cooled semen. The development of an extender that results in high post-thaw sperm quality and acceptable litter size requires identification of factors that markedly impact post-thaw semen quality. The present study aims to first identify factors in boar sperm cryopreservation that significantly impacts post-thaw sperm quality using an efficient, cost-effective, and relatively rapid approach. The Plackett-Burman experimental design is ideal for the screening of factors at their extreme, greatly reducing the amount of time and resources needed for a follow-up, full factorial design. Using commercial semen, a 9 factor, 12 run Plackett-Burman design was used on 10 boars split between 12 treatments. Via this method glycerol concentration, cooling rate, antioxidant supplementation with GameteGuard(Membrane Protective Technologies, Inc. Fort Collins, CO), and straw size were identified as highly influential factors that impact post-thaw sperm quality. Extender type, starting osmolality, sodium dodecyl sulfate addition, and stepwise addition of glycerol were also influential for some but not all post-thaw sperm parameters (p<0.05). Equilibration time in the straws before freezing was determined to have no impact on post thaw sperm quality parameters. Using the Plackett-Burman design, it can be concluded that four of the nine factors warrant detailed investigation in a full factorial experiments in development of boar sperm cryopreservation extenders.

Abstract
INTRODUCTION The trace elements concentrations of blood might play a key role in the trace element concentration of seminal plasma, as well as in the improvement of semen volume and sperm morphology in boars. OBJECTIVE To assess the effect of supplementation of Cu, Zn and Mn on their concentrations in blood serum and seminal plasma and sperm quality in boars. METHODS Eighteen boars of the Duroc Jersey breed were selected and their blood and semen (54 ejaculates before supplementation) were extracted. Coinciding with the third sampling and after of blood taken, the boars were supplemented subcutaneously with 37.5 mg of Cu, 75 mg of Zn and 37.5 mg of Mn; 40 days after the supplementation the fourth sampling was taken. Cu and Zn concentrations in blood serum and seminal plasma were determined by atomic absorption spectrophotometry, while the sperm pathologies were determined by microscopy and the concentrations of Cu and Zn in blood serum and seminal plasma, and semen pathologies were compared using the t-Student test for paired samples. A simple linear correlation was made between the minerals concentration in seminal plasma with the percentage of spermatozoa with abnormal forms. RESULTS Although the concentrations of Zn in blood serum did not show differences between sampling periods (P < 0.05), they were significantly higher (P < 0.01) in the seminal plasma after supplementation as compared to its levels before supplementation. In addition, the concentrations of Cu and Zn in seminal plasma were increased (P < 0.01), and the total spermatic pathologies were reduced; especially those of the head, neck and intermediate part of the tail (P < 0.001). Besides, macrocephaly, double head and broken acrosome were the most common pathologies (P < 0.05). Moreover, parenteral supplementation of Cu, Zn and Mn was a protective factor to the presentation of ejaculates with abnormal sperm percentages higher than 10% (χ2 = 6.1544; P = 0.0131). The prevalence of abnormal shapes of boars' sperm before supplementation was 0.40; after supplementation the answer was 0.05 and the prevalence ratio was 0.13 with a confidence interval of 95% from 0.01 to 0.94. Moreover, Zn concentrations in blood serum were not correlated with those of the seminal plasma (P > 0.05, r = - 0.0353); however, the concentrations of Cu in both fluids were correlated (P < 0.05, r = 0.2254). In addition, the Zn values in the seminal plasma and the percentage of abnormal spermatozoa had a negative and highly significant correlation (P < 0.0001, r = - 0.5628). However, the Cu concentrations in the semen were not significantly correlated with the abnormal sperm forms (P > 0.05, r = 0.0200). CONCLUSION From the present study it can be concluded that in boars fed with diets that meeting their requirements in trace minerals according to NRC (2012) [1], parenteral supplementation of 37.5 mg of Cu, 75 mg of Zn and 37.5 mg of Mn increased the Zn concentrations in the seminal plasma and reduced the sperm pathologies, which resulted in an increase of the boars' sperm quality.

Abstract
Cooled preservation of semen is usually associated with artificial insemination and genetic improvement programs in livestock species. Several studies have reported an increase in reactive oxidative species and a decrease in antioxidant substances and sperm quality parameters during long-term semen storage at refrigerated temperatures. The supplementation of antioxidants in extenders before refrigeration could reduce this detrimental effect. Various antioxidants have been tested, both enzymatic, such as superoxide dismutase and catalase, and non-enzymatic, such as reduced glutathione, vitamins E and C and melatonin. However, the problem of oxidative stress in semen storage has not been fully resolved. The effects of antioxidants for semen-cooled storage have not been reviewed in depth. Therefore, the objective of the present study was to review the efficiency of the supplementation of antioxidants in the extender during cooled storage of semen in livestock species.

Abstract
Simple Summary Goat production plays an important economic and social role in Northern Moroccan farming. Beni Arouss is an autochthonous North Moroccan goat breed. The use of artificial insemination can largely contribute to optimised preservation and dissemination of valuable traits of this breed and lead to improved productivity. During liquid storage, the stability of semen good quality remains crucial in order to provide greater flexibility between the artificial insemination center and farms where the insemination of does needs to be performed. The study aims to assess the effect of storage and season of the year on fresh semen of Beni Arouss goats. Every month, ejaculates were collected from bucks and were extended and stored at 16 °C for 24 h. Semen motility, viability and normal morphology were assessed at 0, 4, 8 and 24 h after collection. As expected, these parameters showed a significant reduction within 24 h of storage and during all seasons. However, semen collected in summer maintained a better quality after 24 h of storage at 16 °C than semen collected during the other periods. Therefore, the storage ability of Beni Arouss bucks’ semen stored at 16 °C was higher during the summer. Abstract The study aimed at determining the effect of storage and season on fresh semen of Beni Arouss goats. Ejaculates were collected at monthly intervals from seven mature bucks and were extended at a final concentration of 800 × 106 spermatozoa. ml-1 and stored at 16 °C for 24 h. Semen motility, viability and normal morphology were assessed at 0, 4, 8 and 24 h after collection. Motility and normal morphology parameters were recorded using computer-assisted sperm analysis (CASA) and viability was analyzed using eosin–nigrosin staining. As expected, motility, viability and normal morphology parameters showed a significant reduction within 24 h of storage and during all seasons (p < 0.05). However, semen collected in summer maintained a better quality after 24 h of storage at 16 °C than semen collected during the other periods (p < 0.05). In conclusion, the storage ability of Beni Arouss bucks’ semen stored at 16 °C was significantly higher during the summer.

Period of Boar Ejaculate Collection Contributes to the Yearly Intra-Male Variability of Seminal Plasma Cytokines. BIOLOGY 2020; 9:biology9050105. [PMID: 32443675 PMCID: PMC7285058 DOI: 10.3390/biology9050105] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 05/08/2020] [Accepted: 05/17/2020] [Indexed: 12/11/2022]
Abstract
The concentrations of cytokines in seminal plasma (SP) fluctuate over time in healthy males, weakening their practical usefulness as diagnostic tools. This study evaluated the relevance of intra-male variability in SP cytokines and to what extent the period of the year when ejaculate is collected contributes to such variability. Thirteen cytokines (GM-CSF, IFNγ, IL-1α, IL-1β, IL-1ra, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-18, and TNFα) were measured using the Luminex xMAP® technology for 180 SP samples of ejaculate collected over a year from nine healthy and fertile boars. The SP samples were grouped into two annual periods according to decreasing or increasing daylight and ambient temperature. Intra-male variability was higher than inter-male variability for all cytokines. All SP cytokines showed concentration differences between the two periods of the year, showing the highest concentration during the increasing daylength/temperature period, irrespective of the male. Similarly, some cytokines showed differences between daylength/temperature periods when focusing on their total amount in the ejaculate. No strong relationship (explaining more than 50% of the total variance) was found between annual fluctuations in SP-cytokine levels and semen parameters. In conclusion, the period of the year during which ejaculates were collected helps explain the intra-male variability of SP-cytokine levels in breeding boars.

Abstract
This study aimed to investigate the effects of Lactobacillus plantarum 16 (Lac16) and Paenibacillus polymyxa 10 (BSC10) on intestinal barrier function, antioxidative capacity, apoptosis, immune response, and biochemical parameters in broilers. A total of 540 one-day-old broiler chicks (Cobb500) were randomly allocated to three groups of 180 birds, and fed either a basal diet or a basal diet supplemented with 108 colony-forming units Lac16 or BSC10 per kilogram feed for 21 D. The results revealed that both Lac16 and BSC10 maintained ileal mucosal morphology, and BSC10 regulated the expression of barrier function-related genes. Birds fed with probiotics decreased malondialdehyde level in jejunal mucosa and serum, and the increased activities of hepatic GSH-Px and jejunal CAT were observed in BSC10 group (P < 0.05). Immunohistochemistry of Bax, Bcl-2 and proliferating cell nuclear antigen and TUNEL-immunofluorescence assay demonstrated that Lac16 and BSC10 exerted beneficial effects on cell apoptosis and proliferation, as indicated by the gene expression of down-regulated Bax and p53 as well as a significant upregulation of Bcl-2 (P < 0.05). In addition, Lac16 and BSC10 significantly increased NO production and iNOS activity in liver and jejunal mucosa, and gene expression of IFN-γ (P < 0.01), IL-6 (P < 0.05), and IL-10 (P < 0.05 and P < 0.01, respectively) in ileum mucosa, whereas markedly decreased the expression of Cox2 (P < 0.05). Furthermore, it was found that Lac16 and BSC10 significantly reduced levels of alkaline phosphatase (P < 0.05 and P < 0.01, respectively) and creatine kinase (P < 0.05). Moreover, BSC10 significantly reduced uric acid (P < 0.05) and low-density lipoprotein levels (P < 0.01). Taken together, Lac16 and BSC10 could improve intestinal and body health status of broilers by increasing intestinal barrier function, anti-oxidative capacity and immunity, and decreasing cell apoptosis with strain-specificity.

Removal of seminal plasma prior to liquid storage of boar spermatozoa: A practice that can improve their fertilizing ability. Theriogenology 2018; 125:79-86. [PMID: 30390482 DOI: 10.1016/j.theriogenology.2018.10.020] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 08/27/2018] [Accepted: 10/25/2018] [Indexed: 11/23/2022]
Abstract
Seminal plasma (SP) plays a vital role in the maintenance of sperm function and integrity along with being involved in their communication with the female reproductive tract. Under in vitro conditions, although it is generally accepted that boar semen is better preserved when SP is diluted (extended) or removed (cryopreserved), its role during storage is not completely elucidated. In this context, the current study sought to determine the role of SP during storage of boar spermatozoa at 17 °C for 72 h. Thus, two treatments were prepared with semen from the sperm-rich fraction (SRF) of boar ejaculate previous to storage in liquid state: 1) PSP: semen directly extended in Beltsville Thawing Solution (BTS), and 2) ASP: semen first centrifuged with subsequent removal of supernatant (containing SP) followed by suspension of sperm in BTS. From this, two experiments were conducted separately in this work: 1) in vitro and 2) in vivo assays. The former aimed to evaluate how sperm capacity responds to in vitro capacitation (IVC) and whether their quality is affected by previous exposure to SP. In the latter, the objective was to understand how important these previous conditions can be for reproductive performance after artificial insemination (AI). According to our results, the previous removal of SP does not affect sperm quality and the response of these cells to IVC (P > 0.05) along with resulting in a lower percentage of acrosome damage in them [12.87 ± 0.76 (ASP) vs. 16.38 ± 0.73 (PSP)] (P < 0.05). This improved preservation of acrosome integrity in the absence of SP can explain the higher fertility rate (%) [63.27 ± 23.47 (ASP) vs. 38.57 ± 16.30 (PSP)] and number of implanted embryos at 28 days after AI (13.71 ± 4.88 (ASP) vs. 7.16 ± 4.02 (PSP)] (P < 0.05) presented by gilts inseminated with seminal doses of ASP. In conclusion, removal of SP prior to liquid storage of boar sperm for 72 h can be beneficial for their fertilizing ability.

Abstract
Seminal plasma (SP), the fluid that surrounds the sperm cells, is known to exert substantial influence on sperm physiology. The SP has a pivotal role in sperm function in vivo, and due to its components, it functions in an ambiguous manner in vitro, simultaneously possessing deleterious and beneficial effects. This experiment aimed to describe the differences between the presence or absence of SP from the sperm-rich fraction on some spermatozoa characteristics (kinetics, plasma and acrosome membrane integrity, lipid peroxidation and capacitation-like changes). Furthermore, this experiment focused on distinguishing the effects of SP on the variables evaluated from the effects of centrifugation during SP removal. Total and progressive sperm motility, as well as integrity of plasma and acrosome membranes, were less (P < 0.05) in the absence of SP. Membrane lipid peroxidation (P < 0.05) and sperm membrane stability (P < 0.05) did not differ among treatments. The SP from the sperm-rich fraction is important for the maintenance of adequate structural and functional characteristics of extended liquid boar semen and should be present in seminal doses throughout storage. Furthermore, the detrimental effect on the variables evaluated was caused solely by the absence of SP and not by the process of removal through centrifugation at 500 x g for 10 min.

Abstract
The key prerequisite for successful insemination is sperm characterized to have positive values for morphological and biological variables which are determined by, among others, effective antioxidant protection during the lifespan of sperm cells. This study evaluated the activity and relative abundance of mRNA for antioxidant enzymes in stallion testicular and epididymal tissues during breeding (n = 5) and non-breeding (n = 5) seasons. The activity of superoxide dismutase (SOD) was greater (P < 0.05) during the breeding season, in particular in the testes and the caput epididymis, and SOD1 was the predominant isoform of the enzyme. The expression of the SOD3 gene was markedly less in the analyzed tissues, which indicates that this enzyme contributes to the antioxidant protection of the stallion reproductive tract. The activity of catalase (CAT) was less (P < 0.05) in the testes during both seasons while its relative abundances only during the breeding season. The greatest CAT activity was noted in the cauda epididymis during the breeding season. The activity of glutathione peroxidases (GPx) was greater (P < 0.05) in the testes than in other tissues and 10-fold greater during the breeding season. Similarly, relative abundance of GPx5 mRNA was greater (P < 0.05) in the caput epididymis than in the remaining tissues during both seasons. This study demonstrated that season has an ambiguous influence on the antioxidant defense system in stallion reproductive tissues. Seasonal differences in the present study, however, indicate that the reproductive system of stallions adapts well to environmental seasonal changes.

Abstract
Although boar semen productivity is affected by seasonality, its effects are not equal among different regions which raise concerns regarding the profitability of boar stud farms. Therefore, the goals of this study were (i) to evaluate the seasonal effect on semen production in a commercial boar stud farm located in a subtropical climate region and (ii) to verify whether the activities of superoxide dismutase and glutathione peroxidase in spermatozoa and seminal plasma were associated with seminal traits of fresh and cooled semen. Nine boars were collected twice per season, and routine seminal parameter analyses were performed together with superoxide dismutase and glutathione peroxidase activities in seminal plasma and spermatozoa. Despite a reduction in sperm concentration in spring and summer, most seminal parameters were constant year-round. Temperature-humidity index was higher in the summer compared to spring, autumn and winter (p < .05). Superoxide dismutase activity in spermatozoa was increased in summer compared to autumn and winter (p < .05). The activities of both enzymes in seminal plasma and spermatozoa glutathione peroxidase remained unaltered throughout the seasons. In conclusion, seasonality showed little influence in overall boar seminal parameters despite microclimatic differences among seasons, and spermatozoa collected during summer increased superoxide dismutase activity.

Abstract
Little is known of how the stress response varies when animals confront seasonal life-history processes. Antioxidant defenses and damage caused by oxidative stress and their link with immunocompetence are powerful biomarkers to assess animal´s physiological stress response. The aim of this study was A) to determine redox state and variation in basal (pre-acute stress) immune function during summer, autumn and winter (spring was not assessed due to restrictions in collecting permit) in the fish-eating Myotis (Myotis vivesi; Chiroptera), and B) to determine the effect of acute stress on immunocompetence and redox state during each season. Acute stress was stimulated by restricting animal movement for 6 and 12 h. The magnitude of the cellular immune response was higher during winter whilst that of the humoral response was at its highest during summer. Humoral response increased after 6 h of movement restriction stress and returned to baseline levels after 12 h. Basal redox state was maintained throughout the year, with no significant changes in protein damage, and antioxidant activity was modulated mainly in relation to variation to environment cues, increasing during high temperatures and decreasing during windy nights. Antioxidant activity increased after the 6 h of stressful stimuli especially during summer and autumn, and to a lesser extent in early winter, but redox state did not vary. However, protein damage increased after 12 h of stress during summer. Prolonged stress when the bat is engaged in activities of high energy demand overcame its capacity to maintain homeostasis resulting in oxidative damage.

Abstract
Boar ejaculates are ejected in fractions with a specific composition in terms of sperm numbers and seminal plasma (SP), which is reflected in the varying sperm cryotolerance observed among different fractions. As boar sperm are particularly sensitive to oxidative stress, this study evaluated the role of SP antioxidants in the observed differences in sperm cryotolerance among ejaculate fractions. Ten ejaculates from five boars were manually collected in fractions: the first 10 mL of the sperm-rich fraction (SRF), the rest of the SRF and the post-SRF. Semen samples comprising the entire ejaculate (EE) were created by proportionally mixing the three fractions described above. Each of the 40 resulting semen samples was split into two aliquots: one was used for sperm cryopreservation following a standard protocol utilizing 0.5-mL straws, and the other was used to collect SP for antioxidant assessment. Frozen-thawed (FT) sperm from the SRF (the first 10 mL of the SRF and the rest of the SRF) and those from post-SRF were of the highest and worst quality, respectively, which was measured in terms of total and objective progressive motility and viability (P < 0.01). Viable FT sperm from the post-SRF generated more reactive oxygen species and experienced more lipid peroxidation than those from the SRF (both the first 10 mL and the rest of the SRF) (P < 0.01). The percentage of FT sperm exhibiting fragmented nuclear DNA did not differ among ejaculate fractions and the EE. Catalase, glutathione peroxidase and glutathione peroxidase 5 (GPx-5) were lowest in SP from the first 10 mL of the SRF (P < 0.001), whereas superoxide dismutase (SOD) and paraoxonase 1 (PON-1) were highest in SP of the SRF (both the first 10 mL and the rest of the SRF) (P < 0.01). Trolox-equivalent antioxidant capacity (TEAC) and the ferric-reducing ability of plasma (FRAP) were highest in SP from the first 10 mL of the SRF and lowest in the post-SRF (P < 0.001), whereas cupric-reducing antioxidant capacity was lowest (P < 0.05) in SP from the first 10 mL of the SRF. Regression analyses indicated that certain SP antioxidants had good predictive value for post-thaw recovery rates of total motility (R2 = 54.8%, P < 0.001; including SOD, TEAC and FRAP) and viability (R2 = 56.1%, P < 0.001; including SOD, PON-1, GPx-5 and TEAC). These results demonstrated that certain SP antioxidants are positively involved in boar sperm cryotolerance, minimizing the oxidative stress imposed by cryogenic handling.

Abstract
The objective of this study was to assess the effects of dietary supplementation of a commercial algal product rich in docosahexaenoic acid (DHA) on boar fertility as assessed in vitro and in vivo. Boars were fed one of three experimental diets for 19 weeks: (i) Control (Ctl) diet (n = 31), (ii) Ctl diet plus 75g All-G-Rich per day (n = 31) or (iii) Ctl diet plus 150g All-G-Rich per day (n = 30). Parameters assessed were (i) raw semen quality; volume, sperm concentration, total motility and morphology (ii) liquid semen quality; progressive motility, viability, hypotonic resistance and acrosomal integrity (iii) frozen-thawed semen quality; motility, thermal stress, viability, membrane fluidity and mitochondrial activity (iv) sperm and seminal plasma (SP) fatty acid composition (FAC) (v) total antioxidant capacity (TAC) of SP and (vi) farrowing rates and litter sizes of sows (n = 1158) inseminated with liquid semen. Boars consuming 75g All-G-Rich had a larger semen volume (P < 0.05) and a higher total sperm number (P < 0.01) than the Ctl treatment, however, there was no effect of treatment on any other semen quality parameter (P > 0.05). There was no effect of dietary treatment on the FAC and TAC of SP or on farrowing rate and litter size (P > 0.05). There was an effect of dietary treatment on the FAC of sperm, represented by an 1.72 and 1.60 fold increase in the DHA content for 75 and 150g treatments, respectively, compared to the Ctl treatment. In conclusion, a significant increase in semen volume and total sperm number in boars supplemented 75g All-G-Rich daily, resulted in an increase in production of 3 to 4 more doses per ejaculate, thus, indicating that the feeding regime described within this study has the potential for increasing the output of boar studs.

Abstract
Reactive oxygen and nitrogen species (ROS-RNS) are important defence substances involved in the immune response against pathogens. An excessive increase in ROS-RNS, however, can damage the organism causing oxidative stress (OS). The organism is able to neutralise OS by the production of antioxidant enzymes (AE); hence, tissue damage is the result of an imbalance between oxidant and antioxidant status. Though some work has been carried out in humans, there is a lack of information about the oxidant/antioxidant status in the presence of tuberculosis (TB) in wild reservoirs. In the Mediterranean Basin, wild boar (Sus scrofa) is the main reservoir of TB. Wild boar showing severe TB have an increased risk to Mycobacterium spp. shedding, leading to pathogen spreading and persistence. If OS is greater in these individuals, oxidant/antioxidant balance in TB-affected boars could be used as a biomarker of disease severity. The present work had a two-fold objective: i) to study the effects of bovine TB on different OS biomarkers (namely superoxide dismutase (SOD), catalasa (CAT), glutathione peroxidase (GPX), glutathione reductase (GR) and thiobarbituric acid reactive substances (TBARS)) in wild boar experimentally challenged with Mycobacterium bovis, and ii) to explore the role of body weight, sex, population and season in explaining the observed variability of OS indicators in two populations of free-ranging wild boar where TB is common. For the first objective, a partial least squares regression (PLSR) approach was used whereas, recursive partitioning with regression tree models (RTM) were applied for the second. A negative relationship between antioxidant enzymes and bovine TB (the more severe lesions, the lower the concentration of antioxidant biomarkers) was observed in experimentally infected animals. The final PLSR model retained the GPX, SOD and GR biomarkers and showed that 17.6% of the observed variability of antioxidant capacity was significantly correlated with the PLSR X’s component represented by both disease status and the age of boars. In the samples from free-ranging wild boar, however, the environmental factors were more relevant to the observed variability of the OS biomarkers than the TB itself. For each OS biomarker, each RTM was defined as a maximum by one node due to the population effect. Along the same lines, the ad hoc tree regression on boars from the population with a higher prevalence of severe TB confirmed that disease status was not the main factor explaining the observed variability in OS biomarkers. It was concluded that oxidative damage caused by TB is significant, but can only be detected in the absence of environmental variation in wild boar.

Total antioxidant capacity, catalase activity, and lipid peroxidation changes in seminal plasma of sex-reversed female and male rainbow trout (Oncorhynchus mykiss) during spawning season. Theriogenology 2016; 86:1975-82. [PMID: 27474236 DOI: 10.1016/j.theriogenology.2016.06.014] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2016] [Revised: 06/12/2016] [Accepted: 06/15/2016] [Indexed: 11/23/2022]
Abstract
The advantages of gender-related characteristics are used in aquaculture practice to improve production. For instance, all-female stock is preferable than mixed or all-male stock in salmonid culture. The most effective way to obtain all-female populations is the using of sex-reversed (SR) female trouts, genotypically female but phenotypically male, by masculinizing androgen hormones as breeders in artificial insemination. This study was conducted to evaluate changes in the total antioxidant capacity (TAC), protein concentration, catalase (CAT) activity, lipid peroxidation level (LPO; malondialdehyde), and Fourier transform infrared spectra of seminal plasma of SR female and normal (N) male trouts during the spawning season. Seminal plasma TAC values of N male and SR female trouts were determined as 0.015 ± 0.004 and 0.116 ± 0.033 mM of Trolox equivalents, respectively, in the middle of the spawning season. Some regions related to aromatic rings in seminal plasma Fourier transform infrared spectra of SR female trouts differed from N male trouts were indicated to the higher TAC values. At the middle of the spawning season, protein concentrations were determined as 569.5 ± 139.4 mg/dL in SR female trouts and 66.3 ± 22.7 mg/dL in N male trouts. LPO levels in seminal plasma of N male trouts varied from 46.33 ± 12.05 × 10(-3) to 270.02 ± 70.64 × 10(-3) nmol/mg protein, whereas from 13.87 ± 4.98 × 10(-3) to 48.49 ± 17.31 × 10(-3) nmol/mg protein in SR female trouts throughout the spawning. CAT activities of seminal plasma in N male trouts ranged from 0.38 ± 0.26 to 0.47 ± 0.32 kU/mg protein, whereas those values in SR female trouts varied between 0.21 ± 0.10 and 0.43 ± 0.15 kU/mg protein. Moreover, there were the pairwise significant correlations among all variables except between CAT and TAC (P > 0.05). Remarkable correlations were found between LPO-protein (r = -0.922, P < 0.05, n = 190), LPO-TAC (r = -0.859, P < 0.05, n = 98), and TAC protein (r = +0.879, P < 0.05, n = 98). Similar to seminal plasma of N male trouts, TAC values, protein concentrations, and CAT activities in seminal plasma of SR female trouts have shown decline, whereas LPO levels increased toward the end of the spawning seasons. Seminal plasmas of SR female trouts were characterized by higher protein concentrations and TAC values and lower LPO levels than that from N male trouts.

Abstract
The objectives of this study were to determine the influence of breed and hybrid genetic traits of boars on lipid and protein concentrations and antioxidative system variables in seminal plasma (SP) and spermatozoa and their correlations with semen quality variables. Semen samples from 27 boars: Swedish Landraces (SL), German Landraces (GL), Large Whites (LW), Pietrains (P) and Pig Improvement Company hybrids (PIC-hybrid), aged from 1.5 to 3 years old, were collected. SP was spectrophotometrically analyzed to determine total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triacylglycerol (TAG), total protein (TP), albumin, and zinc concentrations. The antioxidative system in SP and spermatozoa was established spectrophotometrically by determining total antioxidative status (TAS), total superoxide dismutase (TSOD) and glutathione peroxidase (GSH-Px) parameters, as well as copper-zinc superoxide dismutase (CuZnSOD) and manganese superoxide dismutase (MnSOD) activity in spermatozoa. The hybrid boars had higher (P<0.05) SP concentrations of: TC, LDL-C and TAG than P and GL; HDL-C than P, GL and SL; and TP than P and LW. PIC-hybrid had lower values (P<0.05) in spermatozoa of: TAS and CuZnSOD than SL; TSOD and GSH-Px than SL and P; and MnSOD than SL and LW. Differences in SP and spermatozoa antioxidative system variables and the significant differences in SP protein and lipid variables exist among boars of different breeds and hybrid. Novel data and observed differences in semen variables among boar breeds and hybrids and their correlations with semen quality parameters in this study could contribute to better assessment of boar semen quality.

Abstract
This study investigated the effect of age- and seasonal-related variations in the composition of boar semen over a 3-year period. At the onset of 8 months of age, ejaculates were collected from four boars and allocated into three groups: 8 to 18, 19 to 30, and 31 to 42 months and were divided into two seasonal periods: autumn-winter and spring-summer. Boar variability had a significant effect on most of the analyzed semen parameters. Significantly, higher ejaculate volumes were observed in the boars older than 18 months of age during the autumn-winter period. Sperm concentration was higher in boars less than the age of 18 months of age, whereas the total sperm numbers were significantly higher during the autumn-winter period, regardless of the age group. Seasonal effects in sperm motility were more marked in boars at the age of 19 to 30 months, being significantly higher during the autumn-winter period. The proportions of spermatozoa with intact, normal apical ridge acrosome, and osmotically tolerant acrosomal membranes were markedly higher in boars at the age of 19 to 30 months during the autumn-winter period. Spermatozoa harvested during the spring-summer period were more susceptible to lipid peroxidation, irrespective of the age group. Significantly, higher levels of protein content and concentrations of nonthiol-containing antioxidant components of the seminal plasma (SP) were detected in boars less than 18 months of age during the autumn-winter period. Seasonal effects on the pH and proteinase inhibitory activity in the SP were more marked in boars less than 18 months of age, whereas alkaline phosphatase activity was greater in boars at the age of 19 to 30 months during the autumn-winter period. Substantial amounts of the thiol-containing antioxidants of the SP were detected in boars older than 18 months of age during the spring-summer period. Neither osmolality nor total antioxidant status was affected by differences in the seasonal periods or age groups. The findings of this study indicate that age- and seasonal-related variations affect the reproductive tract functions in the boar, resulting in marked changes in the biochemical composition of the semen.

Abstract
The study attempted to clarify the role of total antioxidant capacity of seminal plasma (SP-TAC) on boar sperm survival and fertility after artificial insemination (AI). SP-TAC differed (P < 0.001) among boars (n° = 15) and, to a lesser degree, among ejaculates within male (4 ejaculates/boar). SP-TAC also differed (P < 0.001) among ejaculate fractions (43 ejaculates and 3 fractions per ejaculate), of which the sperm-peak portion of the sperm rich ejaculate fraction (SRF) had the highest SP-TAC. SP-TAC was not correlated with sperm quality (motility and viability) or functionality (intracellular ROS generation and lipid peroxidation) of liquid AI-semen samples stored at 17 °C for 72 h (90 AI-samples), but the decline in sperm quality was larger (P < 0.05) in ejaculates with low, compared with high SP-TAC (hierarchically grouped). The SP-TAC differences among ejaculate portions agree with sperm cryosurvival rates (14 ejaculates from 7 boars), showing sperm from sperm-peak portion better (P < 0.01) post-thaw quality and functionality than those from the entire ejaculate (mainly post-SRF). Boars (n° = 18) with high SP-TAC (hierarchically grouped) had higher (P < 0.05) fertility outcomes (5,546 AI-sows) than those with low SP-TAC. Measurement of SP-TAC ought to be a discriminative tool to prognosis fertility in breeding boars.

Abstract
Reproductive seasonality has been shown to affect the quality of boar semen. In this study, effects of seasonal variations in the characteristics of spermatozoa and seminal plasma (SP) of fractioned ejaculates from individual boars have been investigated. Fractionated ejaculates, designated as fraction 1 (F1), fraction 2 (F2), and fraction 3 (F3), were collected from five mature boars during the autumn-winter (October through March) and spring-summer periods (April through September). A total of 10 fractionated ejaculates (F1, F2, and F3) were collected from each boar within each seasonal period. Assessments of the sperm quality characteristics included computer-assisted sperm analysis motion patterns, mitochondrial membrane potential (MMP), plasma membrane integrity, normal apical ridge acrosomes, and DNA fragmentation. Besides SDS-PAGE and densitometric analyses of the SP proteins, the antiperoxidant activity was monitored. There were marked differences in the sperm quality characteristics among the boars, except for sperm MMP. Distinct seasonal differences (P < 0.05) were observed in the ejaculate volume of F3 during the autumn-winter and spring-summer periods (107.78 ± 5.45 and 87.80 ± 4.75 mL, respectively). Significantly higher (P < 0.05) sperm concentration and the total number of spermatozoa in the fraction were observed during the autumn-winter period. Seasonal effects in MMP and plasma membrane integrity were manifested in significantly higher (P < 0.05) percentages of spermatozoa with functional mitochondria and intact plasma membrane during the autumn-winter period. However, the seasonal effects were less marked in either sperm normal apical ridge acrosomes or sperm DNA fragmentation. Sodium dodecyl sulfate-PAGE and densitometric analyses revealed marked variations in the protein composition of the SP profiles among the boars, regardless of the ejaculate fraction and seasonal period. Distinct seasonal variations, observed in the SDS-PAGE profiles, were associated with an abundance of protein fractions of low-molecular and high-molecular weight components, particularly during the autumn-winter period. There were wide variations in antiperoxidant activity in the SP among the boars, being significantly higher in the autumn-winter period, irrespective of the ejaculate fraction. It can be suggested that marked deterioration of the quality of fractionated ejaculates during the spring-summer period was probably caused by impaired reproductive function in the boar.
