Dietary Mineral Sources Altered Lipid and Antioxidant Profiles in Broiler Breeders and Posthatch Growth of Their Offsprings

Abstract

The aim of this study was to investigate the influence of mineral sources on broiler breeders and their offsprings. Broiler breeding hens were fed with diets containing either organic or inorganic trace minerals at equal levels, i.e., (1) control group was fed with basal diet supplemented with inorganic trace minerals; (2) OZ group was fed with organic Zn instead of sulfate; and (3) OTM group was fed with organic Cu, Mn, Zn, and Se instead of inorganic sources. Results indicated that OTM supplementation decreased plasma cholesterol and triglyceride and increased yolk triglyceride via increasing high-density lipid protein cholesterol and decreasing low-density lipid protein cholesterol and very low-density lipid protein (VLDL) in plasma. OZ diets decreased plasma cholesterol and triglyceride mainly by reducing VLDL concentration. For control group, increased lipid concentrations resulted in increased lipid peroxidation in serum and malondialdehyde retention in yolk. Zn retention was not affected. Otherwise, OZ diet was observed to decrease Cu in yolk and albumen. While for OTM group, albumen Cu, albumen Se, and hepatic Se of hatched chicks were increased, but yolk Cu was decreased. Moreover, organic mineral supplementations improved broilers' growth performance. In conclusion, organic mineral supplementation in breeders' diets protected breeders from lipid peroxidation, increased egg nutrition retention, and benefit for growth of broilers.

Yeast Culture Improves Egg Quality and Reproductive Performance of Aged Breeder Layers by Regulating Gut Microbes

“…As our results indicate improvements in egg quality, the increased hatching rate, the improved fertilization rate, and the healthy chick rate can also be associated with the egg quality and the increased eggshell strength and density, which prevent pathogenic microorganisms from entering the eggs. Moreover, YC also contains a large amount of trace elements, such as selenium and zinc that improve embryonic and early postnatal development of the aged layer (Hostetler et al, 2003;Sun et al, 2012). A previous study has shown that adding yeast bioactives significantly improves the level of IgA in the egg yolk (Lu et al, 2019), resulting in enhanced chick immunity and improved reproductive performance of the aged layers.…”

Dietary supplementation with canthaxanthin and 25-hydroxycholecalciferol has beneficial effects on bone and oxidative metabolism in European quail breeders

“…It plays an important role in calcium and phosphorus metabolism by acting on the absorption and recycling of calcium in the intestine ( Berridge et al., 2003 ). Consequently, it can increase the concentration of circulating calcium for egg production ( Sun et al., 2012 ), positively influencing the laying rate, shell quality, embryonic development, bone tissue growth, and hatching ( Saunders-Blade and Kover ).…”

Effects of inorganic trace minerals replaced by complexed glycinates on reproductive performance, blood profiles, and antioxidant status in broiler breeders

“…Zn as a component of Cu/Zn-SOD protects proteins and enzymes from radical attacks, and second, Zn prevents the free radicals' formation from other metals (Fe and Cu) ( Kucuk, 2008 ). It is also demonstrated in previous studies that broiler breeders showed better antioxidant status by feeding organic Zn as compared to inorganic form ( Zhang et al., 2017 ) and reduced the level of serum and liver MDA ( Sahin et al., 2005 , Sun et al., 2012 ). In line with the present findings, it is suggested by other studies that broiler breeders show better antioxidant status by feeding OTM compared with ITM ( Wang et al., 2019a ).…”
