Effect of pre-treatment of melatonin on superovulation response, circulatory hormones, and miRNAs in goats during environmental heat stress conditions. Vet Res Commun 2024; 48:459-474. [PMID: 37831382 DOI: 10.1007/s11259-023-10239-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 10/10/2023] [Indexed: 10/14/2023]
Abstract
Environmental heat stress has a deleterious impact on farm animal reproductive performance. The purpose of this study was to see how the addition of melatonin affected the efficacy of the superovulation regimen in goats in hot climatic conditions. Sixteen Shiba goats were synchronized and divided into two equal groups (n = 8, each): the melatonin group, which received a single S/C dose of melatonin, and a control group, treated with one ml of corn oil only. Ultrasonographic assessment of ovarian structures (Graafian follicles; GFs and corpus lutea; CLs) morphometry and hemodynamics were performed during the estrous phase of the superovulation (D0) and at day7 after ovulation (D7) of the superovulation regimen. The peripheral reproductive hormones were measured, and microRNAs were characterized. The mean diameter and the total-colored area of GFs during the D0 were significantly (P˂0.05) higher in the melatonin group (5.42 ± 0.11 mm and 1592.20 ± 45.26 pixels, respectively) compared to the control group (4.62 ± 0.12 mm and 1052.55 ± 29.47 pixels, respectively). Concentrations of LH and E2 increased significantly (P˂0.05) in the melatonin group (1.06 ± 0.06 ng/ml and 46.34 ± 2.77 pg/ml, respectively) compared to the control group (0.75 ± 0.12 ng/ml and 29.33 ± 1.89 pg/ml, respectively). At D7, the melatonin-received goats attained greater values in the mean count (6.75 ± 0.33, P˂0.005), diameters (6.08 ± 0.12 mm, P˂0.01), and total-colored area (17137.30 ± 128.53 pixels, P˂0.01) of detected CLs and progesterone concentrations (4.08 ± 0.24 ng/ml) compared to control goats (4.00 ± 0.28, 4.50 ± 0.19 mm, 11156.87 ± 117.90 pixels, and 2.90 ± 0.18 ng/ml respectively). MiRNA expression analysis was identified during both stages denoting several up and downregulated miRNA candidates among the studied groups. In conclusion, incorporating melatonin enhanced the efficiency of the superovulation regimen in goats under hot climatic conditions.

Abstract
The present study was conducted to test a new super-agonist recombinant bovine FSH (rbFSH) to induce superovulation (SOV) in dromedary camels. In experiment I, a single IM injection of 40, 60, 80, 100, or 120 µg rbFSH was administered (4 donors per group) to determine the effective dose resulting in acceptable multiple ovulation and embryo yield. Administration of 40 µg was ineffective, while 100 and 120 µg were associated with increased numbers of developed follicles, corpora lutea, and recovered embryos compared to administration of 60 and 80 µg. In experiment II, donors were divided into treatment groups to compare rbFSH with two conventional protocols for SOV. Donors received a single dose of 2000 IU eCG in combination with 400 mg porcine follicle-stimulating hormone (pFSH; Folltropin-V®; Group 1, n = 29) or 500 µg of pFSH with 100 µg of pLH (Stimufol®; Group 2, n = 16). Group 3 (n = 19) received a single dose of 100 µg rbFSH. No difference was found in the size and number of follicles per donor. Response time, ovulation rate, and the number of corpora lutea and recovered embryos per donor were similar in all groups. The number of medium-sized and transparent embryos decreased while the number of small-sized and semi-transparent embryos increased in Group 3 (rbFSH) compared to the other two groups. The pregnancy rate of the recipients at 10 days post-ET, at two months of gestation, and the rate of early pregnancy loss (EPL) did not differ among the groups. In conclusion, a single IM administration of 100 µg rbFSH induces a successful superovulation in dromedary camels and has the advantage of reducing stress associated with multiple FSH administration of the conventional protocols.

Effects of recombinant FSH (bscrFSH) and pituitary FSH (FSH-p) on embryo production in superovulated dairy heifers inseminated with unsorted and sex-sorted semen. Anim Reprod Sci 2023; 252:107226. [PMID: 37027990 DOI: 10.1016/j.anireprosci.2023.107226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 03/22/2023] [Accepted: 03/27/2023] [Indexed: 03/30/2023]
Abstract
Superovulation is a drug-based method used in cattle to stimulate the ovarian folliculogenesis and the number of oocytes and transferable embryos. The present study aimed to test the effects of recombinant FSH (bscrFSH) and pituitary FSH (FSH-p) on ovarian response and in vivo embryo production in superovulated dairy heifers inseminated with unsorted and sex-sorted semen. Forty healthy Holstein heifers subjected to a superovulation (SOV) protocol by using FSH-p or bscrFSH were divided randomly into four groups: a) FSH-p inseminated with unsorted semen (USP; n = 10), b) FSH-p inseminated with sex-sorted semen (SSP; n = 10), c) bscrFSH inseminated with unsorted semen (USR; n = 10), and d) bscrFSH inseminated with sex-sorted semen (SSR; n = 10). Ultrasonography was carried out on Day 8 (estrus) and Day 15 (embryo collection) to evaluate the ovarian structures [follicles (FL), corpora lutea (CL), and non-ovulated follicles (NOFL)]. Embryonic-derived parameters were scored on Day 15 [total structures collected (TS), unfertilised oocytes (UFOs), total embryos (TEs), transferable embryos (TFEs), freezable embryos (FEs), and degenerated embryos (DEs)]. No differences were observed regarding ovarian structures (FL and NOFL) irrespective of SOV protocol or group assessed (P > 0.05). CL increased in bscrFSH-derived SOV protocol (P < 0.05). On Day 15, the embryonic-derived parameters TEs, TFEs, and FEs decreased in SSP/SSR compared to USP/USR (P < 0.05). Differences were observed regarding UFOs, with a greater number in SSP and SSR (P = 0.01). In conclusion, the bscrFSH-derived SOV protocol showed improved results compared to FSH-p-derived SOV protocol regarding ovarian (CL) and embryo-derived (TFE) parameters irrespective of the type of semen used.

Domest Anim Endocrinol 2023; 82:106765. [PMID: 36219897 DOI: 10.1016/j.domaniend.2022.106765] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 08/31/2022] [Accepted: 09/01/2022] [Indexed: 01/18/2023]
Abstract
The present study investigated the effect of a single administration of long-acting follicle simulation hormone (FSH) on testicular blood perfusion as measured by pulsed-wave Doppler ultrasonography, testicular echotexture, and circulating testosterone (T), estradiol (E2), and nitric oxide (NO) in the plasma of rams in the non-breeding season. Twelve Ossimi rams were subjected to either a single administration of long-acting FSH subcutaneously (FSH group; n = 6) or the vehicle (control group; n = 6). Assessment of testicular hemodynamics at the level of the supratesticular artery was performed just before administration (0 h), and at 4, 24, 48, 72, 96, and 168 h after FSH or the vehicle administrations. Testicular volume (TV), and echotexture of testicular parenchyma including pixel intensity and heterogeneity were derived by the computer analysis software. Concentrations of T, E2, and NO were measured using commercial kits. Results revealed significant decreases (P ˂ 0.05) in the values of Doppler indices (resistive index: RI and pulsatility index: PI), especially at 48 h after administration of FSH (RI: 0.42 ± 0.02, PI: 0.56 ± 0.04) compared to their values in the control group (RI: 0.54 ± 0.03, PI: 0.77 ± 0.04). FSH administration induced significant decreases (P ˂ 0.05) in the pixel intensity of testicular parenchyma. Testicular volume and T concentrations were not significantly changed (P ˃ 0.05). Concentrations of E2 increased significantly (P ˂ 0.05) at 48 h and 72 h after FSH administration. (30.07 ± 5.23 pg/ml, 29.93 ± 1.44 pg/ml, respectively) compared to their values before FSH administration (14.63 ± 1.37 pg/ml). Concentrations of NO increased significantly (P ˂ 0.05) in the FSH group between 4 h to 48 h compared to the values in the control one. In conclusion, a single administration of long-acting FSH enhanced testicular blood perfusion as measured by pulsed Doppler ultrasonography in rams during the non-breeding season. Concurrently, significant increases in the concentrations of E2 and NO were found.

Effects of Extra-Long-Acting Recombinant Bovine FSH (bscrFSH) on Cattle Superovulation. Animals (Basel) 2022; 12:ani12020153. [PMID: 35049777 PMCID: PMC8772581 DOI: 10.3390/ani12020153] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/04/2022] [Accepted: 01/07/2022] [Indexed: 12/11/2022] Open
Abstract
Over the last few years, several commercial FSH products have been developed for cattle superovulation (SOV) purposes in Multiple Ovulation and Embryo Transfer (MOET) programs. The SOV response is highly variable among individuals and remains one of the main limiting factors in obtaining a profitable number of transferable embryos. In this study, follicle stimulating hormone (FSH) from different origins was included in two SOV protocols, (a) FSH from purified pig pituitary extract (NIH-FSH-p; two doses/day, 12 h apart, four consecutive days); and (b) extra-long-acting bovine recombinant FSH (bscrFSH; a single dose/day, four consecutive days), to test the effects of bscrFSH on the ovarian response, hormone profile levels, in vivo embryo production and the pluripotency gene expression of the obtained embryos. A total of 68 healthy primiparous red Angus cows (Bos taurus) were randomly distributed into two experimental groups (n = 34 each). Blood sample collection for progesterone (P4) and cortisol (C) level determination was performed together with ultrasonographic assessment for ovarian size, follicles (FL) and corpora lutea (CL) quantification in each SOV protocol (Day 0, 4, 8, and 15). Moreover, FSH profiles were monitorised throughout both protocols (Day 0, 4, 5, 6, 7, 8, 9, 10, and 15). In vivo embryo quantity and quality (total structures, morulae, blastocysts, viable, degenerated and blocked embryos) were recorded in each SOV protocol. Finally, embryo quality in both protocols was assessed by the analysis of the expression level of crucial genes for early embryo development (OCT4, IFNt, CDX2, BCL2, and BAX). P4 and cortisol concentration peaks in both SOV protocols were obtained on Day 15 and Day 8, respectively, which were statistically different compared to the other time-points (p < 0.05). Ovarian dimensions increased from Day 0 to Day 15 irrespective of the SOV protocol considered (p < 0.05). Significant changes in CL number were observed over time till Day 15 irrespective of the SOV protocol applied (p < 0.05), being non- significantly different between SOV protocols within each time-point (p > 0.05). The number of CL was higher on Day 15 in the bscrFSH group compared to the NIH-FSH-p group (p < 0.05). The number of embryonic structures recovered was higher in the bscrFSH group (p = 0.025), probably as a result of a tendency towards a greater number of follicles developed compared to the NIH-FSH-p group. IFNt and BAX were overexpressed in embryos from the bscrFSH group (p < 0.05), with a fold change of 16 and 1.3, respectively. However, no statistical differences were detected regarding the OCT4, CDX2, BCL2, and BCL2/BAX expression ratio (p > 0.05). In conclusion, including bscrFSH in SOV protocols could be an important alternative by reducing the number of applications and offering an improved ovarian response together with better embryo quality and superior performance in embryo production compared to NIH-FSH-p SOV protocols.

Gene 2021; 802:145867. [PMID: 34352299 DOI: 10.1016/j.gene.2021.145867] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 07/13/2021] [Accepted: 07/30/2021] [Indexed: 12/20/2022]
Abstract
Genome-wide association studies (GWAS) have identified DENND1A as a potential candidate gene linked to the fertility-related phenotypes in dairy cows. However, to date, no studies have examined the association of the DENND1A insertion/deletions (indels) to bovine fertility on a large scale. Herein, two indel sites, including P4-del-26-bp and P8-ins-15-bp were identified in 1064 Holstein cows. The values of the minor allelic frequency (MAF) ranged between 0.471 (deletion) and 0.230 (deletion), respectively, and combined four different haplotypes by analyzing the haplotype combination. It is noteworthy that P4-del-26-bp is associated with the ovarian width (P = 0.0004) and corpus luteum diameter (P = 0.004). Meanwhile, P8-ins-15-bp was found to have a significant association with the ovarian width (P = 0.020), ovarian weight (P = 0.004), the number of mature follicles (P = 0.020), and diameter of the mature follicles (P = 0.016). Furthermore, the combinatorial analysis showed that the two indel combined-genotypes were significantly related to several reproductive traits (ovarian width, ovarian weight, etc.). Collectively, our findings indicated that these two novel indels and their combinations are correlated with the reproductive traits, and hence, they can serve in the marker-assisted selection (MAS) in cattle breeding. Nevertheless, further functional experiments are needed for understanding the mechanisms of these indels in cattle reproduction in a better way.
