“…Frozen thigh and breast samples (right sides of the carcass) were trimmed to 2 cm × 1 cm × 1 cm (length × width × thickness), placed in a plastic bag and fastened to avoid evaporation and left at 4 °C, and the final weight was determined at 24 h postmortem. Percentage of drip loss was calculated by 100 × (initial muscle weight – final muscle weight/initial muscle weight) as described by Akbari Moghaddam Kakhki et al. (2017).…”

This study examined the effects of sources and levels of selenium (Se) on performance, carcass parts yield, meat quality and tissue Se concentration in broilers. A total of 960 one-day-old male broilers were divided into 8 treatments in a 4 × 2 factorial arrangement. Chicks were penned in groups of 20 with 6 pens per group. Selenium sources were sodium selenite (SS), Se enriched yeast (SY), DL-selenomethionine (SM) and nano-selenium (NS) and dietary supplemental Se levels were 0.1 and 0.3 mg/kg diet. The average daily gain (ADG), average daily feed intake (ADFI), feed:gain ratio, mortality, and carcass parts yield were not affected by dietary treatments. The level of 0.3 mg/kg Se decreased lightness and increased yellowness of the breast and thighs (P < 0.001). Nano-selenium improved yellowness, redness and meat quality (P < 0.05). The interactive effects of sources and the levels of Se affected Se retention (P < 0.001). Inorganic Se showed poor retention compared to other sources of Se; and NS showed equal retention with the organic sources. With consideration to meat quality responses, NS had a more significant positive effect compared to SS as an inorganic source of Se. Overall, NS and organic sources of Se resulted in better meat quality compared with the inorganic source. Moreover, the highest Se retention percentage was achieved by supplementation of NS followed by organic sources at 0.1 mg/kg compared to SS.

“…At 24-h postmortem, right side of breast and thigh muscles were used for pH measurement using a pH meter (model 691 Laboratory pH Meter, Metrohm Co, Herisau, Switzerland) instrument at a depth of 2.5 cm below the surface, as described by Akbari Moghaddam Kakhki et al. (2017).…”

“…Contrasting results were found by Kakhki, Bakhshalinejad, Hassanabadi and Ferket (2017), who evaluated the effect of three levels of alpha-tocopherol acetate (0, 150 and 300 mg / kg of food) and three levels of zinc (0 , 60 and 120 mg / kg of feed) on performance, meat quality and the amount of zinc, selenium and alpha-tocopherol in the breast and thigh muscle and liver of broilers. The authors noted that zinc and alphatocopherol acetate did not influence carcass performance or yield parameters; however, alpha-tocopherol and zinc supplementation increased alpha-tocopherol deposition in the liver, chest and thigh.…”

This study aimed to evaluate the performance and meat quality of broilers fed different levels of alpha-tocopherol. A total of 240 one-day-old Cobb 500® male broiler chicks were reared until day 7 of life, as recommended by the commercial line, and were fed at only 50% of the alpha-tocopherol requirement. At day 8, the chicks were weighed, homogenized, and allotted in a completely randomized design with four treatments (50, 100, 150, and 200% alpha-tocopherol requirement) and six replicates of ten chickens per experimental unit. Several variables were evaluated: weight gain, feed intake, feed conversion, carcass yield and prime cuts (drumstick, thigh, and breast), edible viscera (heart, liver, gizzard), immune organs (cloacal bursa and spleen), intestine weight and length, abdominal fat, breast meat color (lightness, redness, and yellowness), pH, cooking loss, and shear force of the breast meat. Dietary alpha-tocopherol levels did not influence broiler performance, carcass yield, and prime cuts at 42 days of age. The edible viscera, immune organs, the length of the small intestine, and the abdominal fat, as well as the meat color (lightness, redness, and yellowness), pH, cooking loss, and shear force of the breast meat, were not influenced. However, the small intestine yield increased linearly with increasing levels of alpha-tocopherol. The dietary levels of alphatocopherol did not influence the performance and meat quality of broilers from 8 to 42 days of age.

“…The significant increase in zinc concentration in both liver and brain tissues of ZnO-NP-treated Japanese quails compared to the control confirmed that tissue mineral biodistribution can be used as an index of mineral storage in the body [ 37 ]. Previous works indicated that Zn levels in the liver and other tissues were significantly increased by dietary inclusion of Zn either in the form of zinc oxide [ 40 ] or nano-zinc oxide [ 41 ] in broiler chickens. The retention of zinc in either liver or brain tissue was dose independent.…”

Impact of dietary zinc oxide nanoparticles on selected serum biomarkers, lipid peroxidation and tissue gene expression of antioxidant enzymes and cytokines in Japanese quail

et al. 2020

Background The use of zinc oxide in the form of nanoparticles (ZnO-NPs) is of great benefit due to its potent effectiveness and higher bioavailability compared to zinc oxide. This study aimed to investigate the impact of dietary inclusion of different doses of ZnO-NPs on selected serum biomarkers, lipid peroxidation and tissue gene expression of antioxidant enzymes and cytokines in Japanese quail. Eighty Japanese quails (Coturnix japonica) (45 days old) were randomly divided into four groups (20 birds for each) with 4 replicates (5 birds each). Birds in the first group were fed a basal diet alone and served as a control (C). Birds in groups 2–4 were fed the basal diet supplemented with ZnO-NPs at doses of 15 mg/kg, 30 mg/kg and 60 mg/kg for a period of 60 days. At the end of the experiment, all birds were sacrificed to collect blood in a plain vacutainer, whereas liver and brain tissues were stored frozen at -80 °C. The obtained sera were used for the analysis of selected biochemical parameters, whereas tissue homogenates were used for the estimation of zinc, oxidative stress biomarkers and gene expression of selected antioxidant enzymes and cytokines. Results ZnO-NPs (30 and 60 mg/kg) induced a significant decrease in serum triacylglycerol (TAG) compared to the control. ZnO-NPs did not affect the activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein, albumin, globulin and tissue zinc concentrations but reduced the malondialdehyde (MDA) levels compared to the control. The liver retained a higher zinc concentration than that of brain tissue. In a dose-dependent manner, ZnO-NPs upregulated the mRNA levels of antioxidant enzymes (superoxide dismutase: SOD1; catalase: CAT; glutathione peroxidase-1: GPX 1) and pro-inflammatory cytokines (interferon α: IFN-α; interleukin 6: IL-6) in liver and brain tissues. Conclusion The current study suggests the inclusion of ZnO-NPs, particularly 60 mg/kg, in the diet of Japanese quails to improve antioxidant and immune status.
