The effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs.
An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...
متن کاملShort periods of incubation during egg storage increase hatchability and chick quality in long-stored broiler eggs.
It is recognized that cool egg storage for 8 d or longer, commonly employed in broiler parent and commercial layer production, reduces hatchability. In this study, we investigated the efficacy of short periods of incubation during egg storage (SPIDES) in the restoration of hatchability of broiler hatching eggs stored for 21 d. Prolonged cool storage reduced hatchability of untreated eggs from 9...
متن کاملEstimate the contribution of incubation parameters influence egg hatchability using multiple linear regression analysis
AIM This research was conducted to determine the most affecting parameters on hatchability of indigenous and improved local chickens' eggs. MATERIALS AND METHODS Five parameters were studied (fertility, early and late embryonic mortalities, shape index, egg weight, and egg weight loss) on four strains, namely Fayoumi, Alexandria, Matrouh, and Montazah. Multiple linear regression was performed...
متن کاملEffect of ascorbic acid and cooling during egg incubation on hatchability, culling, mortality, and the body weights of broiler chickens.
Five experiments involving 3,100 settable eggs with living embryos of commercial broiler parent stock were conducted to determine the effect of ascorbic acid (AA) and cooling during egg incubation on embryonic weight, hatchability, percentage of cull chicks, embryonic mortality, and body weights of the hatched chicks. The treatments were carried out at 15, 15, 17, 11 and 19 d of incubation for ...
متن کاملInfluence of air composition during egg storage on egg characteristics, embryonic development, hatchability, and chick quality.
Egg storage beyond 7 d is associated with an increase in incubation duration and a decrease in hatchability and chick quality. Negative effects of prolonged egg storage may be caused by changes in the embryo, by changes in egg characteristics, or by both. An adjustment in storage air composition may reduce negative effects of prolonged egg storage because it may prevent changes in the embryo an...
