Effect of Hen Oviposition Time on some Egg Characteristics [PDF]
Ovulation in chicken is the process of emergence the egg yolk by controlling the steroid hormones, which is followed by oviposition that influence by several factors. Egg yolk is a huge oocyte contains fat in water emulsion with about 50% dry weight, its

Body weight and egg weight dynamics in layers
The association between body weight-age and egg weight-age patterns was studied in a segregating population of laying hens belonging to the F3 generation of a Rhode Island Red x White Leghorn reciprocal cross. Body weight and egg weight were expressed as a function of time using the model developed by Weatherup and Foster. Each hen was characterized in

Heritability estimates of egg weight and egg shell weight in Ikenne, Nigeria
This study is designed to determine the inheritance pattern of egg weight and egg shell weight of exotic laying chickens at 25, 51, 72 weeks and overall mean ages of the birds. For this purpose, thirty eggs were collected daily from the birds continuously for five days of egg production, at each ages 25, 51 and 72 weeks.

Abstract THE results of selection and crosses involving differences in weight or size of eggs establish conclusively that heredity is a basic factor in determining egg weight. However, various conclusions relative to the number of genes operating, the mode of their expression, and the contributions of the male and female have been postulated, many of
