Controlled Egg Weight Loss During Incubation of Turkey Eggs

Poultry Science, 1987
Weight loss (12%) of turkey eggs in a commercial incubator by a weekly adjustment of relative humidity (RH) was compared in four independent trials with the industry standard of maintaining 58% RH. Trials 1 and 2 were conducted with eggs from one flock of recycled hens during their 14th and 20th week of lay, respectively.

Heritability estimates of egg weight and egg shell weight in Ikenne, Nigeria

International Journal of Scientific World, 2017
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.

Inheritance of Egg Weight

Poultry Science, 1952
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
