Effect of egg weight and position relative to incubator fan on broiler hatchability and chick quality.
Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...
متن کاملThe Effect of in ovo Injection of Royal Jelly on the Hatchability, Quality of One Day Broiler Chickens, the Performance and some Immune Related Traits in Hatched Chickens
In order to investigate the effect of in ovo injection of different levels of royal jelly on the hatchability rate and the quality of one-day-old broiler chickens (Ross 308) and some traits of the immune system, we have conducted an experiment using 640 eggs in a completely randomized design with four levels of royal jelly injection including 1) 1 mL of physiological serum (control), 2...
متن کاملEffect of in Ovo Injection of Different L-Arginine Levels on Hatchability, Growth Performance and Meat Quality of Ross 308 Broiler Chickens
Previous studies indicated the positive impact of dietary supplementation of arginine on meat quality and growth, though there is no report regarding the effect of in ovo injection of arginine on meat quality. So, the aim of this study was to evaluate the effect of in ovo injection of different levels of L-arginine on hatchability, growth performance, and meat quality of Ross 308 broiler ch...
متن کاملEffect of in ovo Feeding and Dietary Feeding of Silybum marianum Extract on Performance, Immunity and Blood Cation-Anion Balance of Broiler Chickens Exposed to High Temperatures
This experiment was conducted to investigate the effect of in ovo feeding (IOF) and dietary feeding of Silybum marianum (SM) extract on the immunity of chicken under heat stress conditions. A total of 360 fertile eggs from a commercial broiler breeder (Ross-308) farm was used for in ovo feeding of 0, 100 and 200 mg/L SM water extract at day 17.5 of incubation. After hatching, 240 chicks were tr...
