“…The amount of minerals in yolk reflects that the uptake content and enrichment can have beneficial effects [113]. In-ovo supplementation of minerals has improved bone properties and development in hatchlings and mature broilers [113,114,115].…”

“…Fatty acid supplementation, especially of ω-3 and ω-6, helps in improving fertility, semen quality and quantity. Kelso et al [114] found that dietary fish oil or corn oil supplementation to chickens at a level of 50 g/kg in their diet led to significantly higher (96%) fertility rates than the rates prior to supplementation (89%). Kelso et al [115] noticed that the supplementation of ALA in male diets led to higher fertility at 39 weeks of age because of the increased ω-3 fatty acid proportion in the phospholipids of sperm.…”

Omega-3 (ω-3) and omega-6 (ω-6) fatty acids are important components of cell membranes. They are essential for health and normal physiological functioning of humans. Not all fatty acids can be produced endogenously owing to the absence of certain desaturases; however, they are required in a ratio that is not naturally achieved by the standard diet of industrialized nations. Poultry products have become the primary source of long-chain polyunsaturated fatty acids (LC-PUFA), with one of the most effective solutions being to increase the accretion of PUFAs in chicken products via the adjustment of fatty acids in poultry diets. Several studies have reported the favorable effects of ω-3 PUFA on bone strength, bone mineral content and density, and semen quality. However, other studies concluded negative effects of LC-PUFA on meat quality and palatability, and acceptability by consumers. The present review discussed the practical application of ω-3 and ω-6 fatty acids in poultry diets, and studied the critical effects of these fatty acids on productive performance, blood biochemistry, immunity, carcass traits, bone traits, egg and meat quality, and semen quality in poultry. Future studies are required to determine how poultry products can be produced with higher contents of PUFAs and favorable fatty acid composition, at low cost and without negative effects on palatability and quality.

“…Development and growth of poultry embryos are dependent upon the nutrient deposits in the eggs [19]. The yolk sac provides the chicken embryo with essential minerals nutrients for embryonic growth [20,21]. Zinc is an essential nutrients required in small amounts for normal growth and development of the avian embryo functioning as catalytic or structural cofactors in metal-containing enzymes [1].…”

BackgroundMaternal severe zinc (Zn) deficiency induced oxidative damage and apoptosis in embryos, resulting in growth retardation. Therefore, it is crucial to assess maternal marginal Zn nutritional status for poultry breeders to prevent embryos subjected to severe Zn deficiency. MethodsIn Exp. 1, twelve egg embryos were sampled at incubation day 17 (E17), E20, E23, E26, E29, and E32 (day of hatch) respectively, with 6 replicates of 2 embryo each. The developmental changes of Zn mobilization and Zn transport gene mRNA expression were determined. In Exp. 2, 324 laying duck breeders were randomly allotted into 3 dietary Zn levels (0, 60, and 120 mg Zn/kg diet) with 6 replicates of 18 ducks per replicate. Plasma Zn concentration and erythrocytic Zn metalloenzyme activities in breeders as well as the development, redox status, and gene expression related to oxidation and apoptosis in embryos were measured. Blood samples were collected at the 2th, 4th and 6th weeks of the experiment. ResultsIn Exp. 1, the overall Zn mobilization rates were increased in yolk sac and embryonic liver in response to the increased incubation period, associated with the decreased ZIP10, 13, and 14 mRNA expressions in embryonic liver (P < 0.05). In Exp. 2, with the prolonged dietary Zn depletion, maternal Zn deficiency decreased plasma Zn concentration and erythrocytic alkaline phosphatase activity at the 6th week and inhibited erythrocytic 5'-nucleotidase (5’-NT) activity at 2th week (P < 0.05). On E29 of the maximal rate of Zn mobilization, maternal marginal Zn deficiency increased middle and late embryonic mortality and contents of superoxide anion radical, MDA and PPC, as well as decreasedMT content, CuZnSOD activity, and MT1 mRNA expression in embryonic livers (P < 0.05). Additionally, maternal marginal Zn deficiency increased BCL2-associated X protein and Caspase-9 mRNA expression and decreased B-cell lymphoma-2 mRNA expression in embryonic liver (P < 0.05). ConclusionErythrocytic 5’-NT activity was more rapid and reliable to assess marginal Zn-deficient status in duck breeders. Marginal Zn deficiency impaired hatchability and antioxidant defense system and then induced the oxidative damage and apoptosis in embryonic liver, contributing to the greater loss of embryonic death.
