Abstract
Long photoperiods are used in the broiler industry to maximize animal performance, though the impact on meat quality remains poorly understood. The current study evaluated the impact of photoperiod on functional/physicochemical properties and oxidative stability of meat through broiler processing. Ross 308 broilers (n = 432) were randomly assigned to 4 photoperiod treatments (hours in L = light, D = dark): 20L:4D, 18L:6D, 16L:8D, or 12L:12D with 6 pens per treatment. At 42 D of age, 2 broilers per pen (n = 12 per treatment) were harvested under standard conditions. Broiler tenderloin (M. Pectoralis minor) and leg muscles were removed at 1 D postmortem and frozen/stored at -40°C. After 24 h thawing at 2°C, the samples were deboned, ground, and formed into patties in 3 independent batches. Photoperiod had no impact on pH, water-holding capacity, textural profile, meat emulsion activity index, and thiol content (P > 0.05). The patties from 12L:12D and 16L:8D had lower CIE b∗ (yellowness) values than 18L:6D and 20L:4D (P < 0.05), whereas 12L:12D had lower chroma (color intensity) values than other treatments (P < 0.05). The meat from 20L:4D exhibited lower sarcoplasmic protein solubility than other treatments (P < 0.05), whereas both 20L:4D and 18L:6D exhibited lower total protein solubility than 12L:12D (P < 0.05). Higher transmission values (indication of protein denaturation) were observed in 20L:4D than in other treatments (P < 0.05), whereas 12L:12D also maintained lower values than both 18L:6D and 16L:8D (P < 0.05). There was an interaction (P < 0.05) between photoperiod and display storage on 2-thiobarbituric acid reactive substances values, where the patties from 12L:12D maintained less lipid oxidation compared with the patties from other treatments. Results of this study suggest photoperiod has limited impact on meat quality attributes, though rearing broilers with a 12L:12D lighting schedule may be beneficial in reducing protein denaturation and improving lipid stability.

Effect of chronic cyclic heat stress on the intestinal morphology, oxidative status and cecal bacterial communities in broilers. J Therm Biol 2020; 91:102619. [PMID: 32716869 DOI: 10.1016/j.jtherbio.2020.102619] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Revised: 05/07/2020] [Accepted: 05/08/2020] [Indexed: 01/01/2023]
Abstract
The objective of this study was to examine the effects of chronic cyclic heat stress (HS) on the intestinal morphology, oxidative stress and cecal bacterial communities of broilers. One-day-old Arbor Acres (AA) male broilers (n = 100) were acclimated for 3 weeks and then randomly allocated into two groups, normal control (NC) group (22 ± 1 °C, 24 h/day) and HS group (32 ± 1 °C, 10 h/day lasted for 2 weeks). At 35 d of age, intestinal segments (duodenum, jejunum and ileum) and cecal digesta were collected for detection. HS affected intestinal morphology, inducing epithelial cell abscission, inflammatory cell infiltration, and lamina propria edema. Compared with the NC group, HS significantly decreased (P < 0.01) villus height (VH) and the VH-to-crypt depth (CD) ratio (VCR), increased (P < 0.05) CD in the duodenum and ileum, but had no effect on the VH in the jejunum. Moreover, HS induced oxidative stress with antioxidant enzymes activity decreasing (P < 0.05) while malondialdehyde (MDA) content increasing (P < 0.05) in small intestine. Pearson's correlation analysis indicated that MDA content was negatively correlated with VH (P < 0.05). The result of 16S rRNA sequencing showed that HS exposure impacted cecal microbiota alpha diversity (phylogenetic diversity whole-tree index) and beta diversity. Based on principal coordinate analysis (PCoA) plots for weighted UniFrac metrics and unweighted pair group method with arithmetic mean (UPGMA), there were 8 discriminative features at the genus level (linear discriminant analysis score > 2). Parabacteroides, Saccharimonas, Romboutsia and Weissella were reduced, while Anaerofustis, Pseudonocardia, Rikenella and Tyzzerella were enriched in heat-stressed broilers. Collectively, these results indicated that chronic cyclic HS induced oxidative stress that caused damage to intestinal villus-crypt structures, and then altered the cecal microflora profile.

Abstract
Dietary probiotic supplementation is a promising alternative to antibiotics in the poultry industry, and some studies have found its positive impacts on meat quality attributes. The objective of this study was to evaluate the effects of dietary treatments on oxidative stability of postmortem chicken fillet (M. Pectoralis major) muscles during 7 d of storage under either high oxygen (HIOX) or vacuum (VAC) conditions. A total of 264 Hy-Line Brown laying hens (11 birds per cage) were assigned to 2 different dietary treatments (regular diet or 300 ppm probiotic, Sporulin enhanced diet) before being sacrificed. At 17 wk, one bird per cage from 6 cages per treatment was randomly selected and slaughtered (n = 12). Chicken fillets from both sides were collected and randomly assigned to HIOX or VAC conditions. Within each fillet side, the muscle was divided into 3 portions, assigned to 1 or 7 d storage period, while the caudal portion was allocated as the 0 d samples for proximate composition and fatty acid profiling. Results revealed that the muscle crude compositions were not altered in laying hens that were fed probiotic supplementary diet compared to controls (P > 0.05). However, the muscle samples from probiotic fed laying hens had higher proportions of unsaturated fatty acid (74.76 vs. 71.65%, P < 0.05) and 2-thiobarbituric acid reactive substances (0.79 vs. 0.67 mg malondialdehyde/kg meat, P < 0.05) than the samples from the control. In addition, the probiotic fed laying hens, but not controls, had higher levels of conjugated dienes (3.32 vs. 2.63 μg/g meat) and peroxides (0.40 vs. 0.30 milliequivalent O2/kg fat) in the muscle samples after 7 d of storage (P < 0.05). The results from the present study indicated that postmortem fillet muscles obtained from the laying hens fed with probiotic supplementation would be more prone to be oxidized, especially under more oxidizing conditions (HIOX and extended storage time).

Abstract
The objective of this study was to evaluate the effects of photoperiod on meat quality, oxidative stability, and metabolites of broiler fillet (M. Pectoralis major) muscles. A total of 432 broilers was split among 4 photoperiod treatments [hours light(L):dark(D)]: 20L:4D, 18L:6D, 16L:8D, and 12L:12D. At 42 days, a total of 48 broilers (12 broilers/treatment) was randomly selected and harvested. At 1 day postmortem, fillet muscles were dissected and displayed for 7 days. No considerable impacts of photoperiods on general carcass and meat quality attributes, such as carcass weight, yield, pH, water-holding capacity, and shear force, were found (p > 0.05). However, color and oxidative stability were influenced by the photoperiod, where muscles from 20L:4D appeared lighter and more discolored, coupled with higher lipid oxidation (p < 0.05) and protein denaturation (p = 0.058) compared to 12L:12D. The UPLC-MS metabolomics identified that 20 metabolites were different between the 20L:4D and 12L:12D groups, and 15 were tentatively identified. In general, lower aromatic amino acids/dipeptides, and higher oxidized glutathione and guanine/methylated guanosine were observed in 20L:4D. These results suggest that a photoperiod would result in no considerable impact on initial meat quality, but extended photoperiods might negatively impact oxidative stability through an alteration of the muscle metabolites.

Meat quality traits of European quails reared under different conditions of temperature and air velocity. Poult Sci 2020; 99:848-856. [PMID: 32036981 PMCID: PMC7587630 DOI: 10.1016/j.psj.2019.10.037] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 10/11/2019] [Accepted: 10/13/2019] [Indexed: 11/21/2022] Open
Abstract
This study’s objective was to evaluate the influence of thermal environment and air velocity during the rearing phase on European quail meat quality traits. A total of 1,152 one-day-old European quail chicks were placed inside floor pens within environmental chambers. Each experimental period was approximately 5 wks, with birds slaughtered at 37 d of age. The experimental design consisted of a 2 × 4 factorial arrangement of treatments in completely randomized design with 2 air velocities (0 and 2 m/s) × 4 air temperatures (severe cold [SC], moderate cold, thermal comfort, and moderate heat [MH]). ANOVA, with air velocity and thermal environment as fixed effects, was performed to evaluate the effect of main factors and their interaction on meat quality traits, using the GLM procedure (SAS 9.4). Least square means of treatments effects were compared using Tukey’s test (α = 0.05). Lightness (L∗), redness (a∗), and yellowness (b∗), of quail meat were affected by thermal environment and air velocity (P < 0.05). Initial and final L∗ values were greater for MH (P < 0.05). Meat from birds subjected to 2 m/s air velocity had lower final L∗, but no velocity effect was noted for initial L∗. Quail meat from SC presented higher initial and final a∗ values compared with the other thermal environment groups (P ≤ 0.001). Final a∗ was affected by air velocity (P < 0.05). Initial and final b∗ values for meat from MH were greater, 13.8 and 15.2, respectively, differing from the other treatment environments (P < 0.05). However, air velocity did not influence b∗ values (P > 0.05). Interactions were not significant for pHu (P = 0.993). Thawing loss and shear force were affected by treatments (P < 0.05) but not ultimate pH, drip loss, or sarcomere length. This study demonstrates that thermal environments and air velocity affect quail meat quality traits. Further investigation is recommended to explore effects of air velocity and thermal environment on muscle proteolysis of quail meat quality.

Effect of fisetin and probiotic supplementation on erythrocyte osmotic fragility, malondialdehyde concentration and superoxide dismutase activity in broiler chickens exposed to heat stress. J Vet Med Sci 2018; 80:1895-1900. [PMID: 30404955 PMCID: PMC6305513 DOI: 10.1292/jvms.18-0477] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Accepted: 10/17/2018] [Indexed: 11/24/2022] Open
Abstract
The aim of the study was to evaluate effects of fisetin and probiotic on erythrocyte osmotic fragility (EOF), malondialdehyde (MDA) and superoxide dismutase (SOD) in broiler chickens exposed to heat stress. Sixty day-old broilers were divided into: Group I (control) given distilled water; Group II, fisetin (5 mg/kg); Group III, probiotic Saccharomyces cerevisiae (4.125 × 106 cfu/100 ml); and Group IV, fisetin (5 mg/kg) + probiotic (4.125 × 106 cfu/100 ml) orally for 7 days. Blood samples collected from 42-day-old birds were evaluated for EOF, serum MDA concentration and SOD activity. Percentage EOF at 0.5% NaCl was lower (P<0.05) in fisetin, probiotic and fisetin + probiotic groups (34.26 ± 0.98%, 35.65 ± 0.81% and 34.25 ± 1.98%, respectively) than in controls (48.42 ± 0.40%). The MDA concentrations in broiler chickens administered with fisetin (14.37 ± 1.15 nmol/l), probiotic (5.66 ± 1.06 nmol/l) and fisetin + probiotic (4.136 ± 0.58 nmol/l) were lower (P<0.05) than in controls (22.64 ± 2.95 nmol/l). Activities of SOD were higher (P<0.05) in fisetin, probiotic and fisetin + probiotic broiler chickens (6.34 ± 0.24 IU/l, 5.67 ± 0.09 IU/l and 5.93 ± 0.13 IU/l, respectively) than in controls (5.37 ± 0.09 IU/l). Fisetin + probiotic ameliorated oxidative stress changes in broiler chickens better than fisetin or probiotic alone. In conclusion, administration of fisetin or probiotic and, especially their combination, decreased EOF, lipoperoxidation and increased superoxide dismutase activity in broiler chickens exposed to heat stress.
