and chick mortality, reduces hatchability and growth performances, and requires more feed to grow. Keywords: chicks, egg, performances, storage period, White leghorn I. Introduction Storage of hatching eggs is an indispensable part of hatchery operation, even though storage length and conditions may influence embryonic viability. For a single egg the final outcome is a simple binary response i.e. it either hatches or does not. However, the successful production of a chick is a complex process which requires the fulfilments of several conditions; A hen must produce an egg – hatchability depends on genetic and environmental factors affecting laying ability of a dam.
other factors such as age and body weight of the hen, yolk weight and nutrient intake can influence egg size (Abiola et al., ). Hatchability, chick weight and subsequent growth performance of chicks are closely related to the weight of the egg. In general, chicks bore from excessively small orFile Size: KB. Prolonged cool storage reduced hatchability of untreated eggs from 92 to 71%. The SPIDES treatment, which consisted of four 4-h preincubations at 4- to 5-d intervals during storage, reduced the incubation time and restored hatchability to 84% by lowering both early and late embryo mortality (P = ).

Many of these are important long before the eggs are placed in the incubator.

Evidence is presented that an unidentified factor present in yellow corn and in certain other feedstuffs is necessary for maximum egg weight, egg production, and hatchability of fertile eggs in the by: Hatchability Problem Analysis H.
Wilson Introduction When a problem occurs in hatchability, usually it can be categorized as a hatchery, egg handling, or breeder flock problem. If the problem has originated within the breeder flock, it is probable that it happened at least 4 weeks earlier, assuming 3 weeks of incubation and 1 week of egg.

of fertilized eggs. Supplementation of laying hen dietsCited by: Nutrition does affect the hatchability of eggs, especially in broiler breeders.
This is because once an egg is laid, its ability to become a viable broiler chick is not guaranteed. Fertility can be influenced indirectly by nutrition, and even a fertile egg may fail to yield a viable chick if this egg is missing certain nutrients.

as they are not appropriately guided on the influence of egg weight on chick-hatch weight, hatchability and subsequent growth indices in chicken. Often, the negative effect of this lack of proper guidance manifests itself in the farmer’s inability to maintain a uniform chick-hatch weight and hatchability values in their poultry farms.
