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.

On the Inheritance of Egg Weight
Poultry Science, 1961 Abstract IT IS generally agreed that egg weight is a quantitative trait that depends upon several undetermined genes. Hays (1940, 1941) and Roberts et al. (1952) suggested that the genes affecting egg weight are autosomal, indicating that genes for egg weight are transmitted equally by sires and dams.

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

Poultry Science, 1931 Abstract The records used in the following analysis were obtained at the National Institute of Poultry Husbandry, in 1927–1928. House G consisted of ten pens, each pen containing 40 birds at the beginning of the experiment, September 30th, 1927. The rations fed to the ten pens differed in their constituents. The aim of the experiment was to determine

The effect of egg weight on egg external quality characteristics and hatching performance in pekin ducks [PDF]
Kafkas Universitesi Veteriner Fakültesi Dergisi, 2023 This study aimed to investigate the effect of different egg weights on egg external quality characteristics and hatching performance in Pekin ducks. A total of 800 eggs were divided into three weight categories: "light" (Lo; 82 g).
