Inheritance of hatchability in broiler chickens and its relationship to egg quality traits.
The first objective of this study on broiler breeders was to investigate the genetic basis of variability in hatchability over age using a longitudinal model. Weekly percentage hatch of fertile and hatch of set eggs were available for 23,250 dams mated to 3,106 sires of the same age between the 28th and 54th week of life. Hatch of set was very highly correlated with fertility and showed a simil...
متن کاملChanges in External Egg Traits of Chickens during Pre- and Post-Molting Periods
481 fresh fertilized eggs of three Kurdish local chickens (Black with brown neck, White with shank feathering, and White with non-feathering shank) were collected at pre-molting (355 eggs) and post-molting (126 eggs) stages to evaluate external egg traits. A venine caliper was used to determine the length and breadth of eggs to calculate Shape index. Results indicated that egg weight increased ...
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 کاملRelationship between egg quality traits and hatchability in pure-line white layer strains
Hatchability is a very important trait in a breeding program which has a great economical impact on franchise hatcheries. The variability between and within strains raises the question whether reproductive performance can be improved by selection within lines. The aim of this study is to analyse the genetic background of the hatchability and its correlations between egg quality and production t...
