Effect of in ovo injection of vitamins on the chick weight and post-hatch growth performance in broiler chickens
An experiment was conducted to study the effect in ovo injection of vitamins on the embryonic and post-hatch growth performance. Fertile eggs (n=350) were weighed, distributed in to 7 groups and set in force-draft incubator. On 14 th ED five groups were injected with 100 IU Vitamin-A, 0.5 IU Vitamin-E, 50 mg Vitamin-C, 100 μg Vitamin B1 and 100 μg Vitamin B6 dissolved in 0.5 ml of sterile water...
متن کاملEffect of Post Hatch Feed Deprivation on Yolk-sac Utilization and Performance of Young Broiler Chickens
An experiment was conducted to study the effect of post-hatch feed deprivation on yolk sac utilization and subsequent performance of young broiler chickens (280) up to 35 days of age. The experimental treatments included access to feed at 8 h intervals after hatch, up to 48 h (0, 8, 16, 24, 32, 40 or 48 h). Water was offered ad libitum to all the groups immediately after placement. Results indi...
متن کاملThe effects of suboptimal eggshell temperature during incubation on broiler chick quality, live performance, and further processing yield.
Different incubation conditions can cause eggshell temperature (EST) to deviate from optimum. Two experiments were performed to determine the effect of low EST at the start of incubation and high EST at the end of incubation on hatchability, chick quality, 6-wk live performance, and breast meat yield of broiler chickens. In each experiment, 1,800 eggs from a single flock were divided and set in...
متن کاملChanges in broiler chick tissue concentrations of lipid-soluble antioxidants immediately post-hatch.
The antioxidant protection of the chicken (Gallus gallus) embryo during incubation and early postnatal development plays an important role in chick viability. To assess the antioxidant capacity of the newly hatched chick, we determined the concentrations of vitamin A, vitamin E, carotenoids and coenzyme Q₁₀ in the major tissues of chicks which had been held in an incubator for up to 36 h post-h...
متن کاملEffect of in ovo supplementation of nano forms of zinc, copper, and selenium on post-hatch performance of broiler chicken.
BACKGROUND AND AIM Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the stud...
