On the Inheritance of Egg Weight
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.

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

Egg breakfast enhances weight loss [PDF]
To test the hypotheses that an egg breakfast, in contrast to a bagel breakfast matched for energy density and total energy, would enhance weight loss in overweight and obese participants while on a reduced-calorie weight loss diet.Men and women (n=152), age 25-60 years, body mass index (BMI) >or=25 and

Prediction of internal egg quality traits of Potchefstroom Koekoek and Lohmann Brown layers using classification and regression tree method [PDF]
Egg quality traits are features of eggs that influence the general quality of the egg. This study aimed to establish models for the prediction of albumen weight and yolk weight in Potchefstroom Koekoek and Lohmann Brown layers with a classification and ...

The effect of egg weight on egg external quality characteristics and hatching performance in pekin ducks [PDF]
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).

The Relationship of Egg Weight to Hatchability of Coturnix Eggs
Abstract This report relates size to hatchability of Coturnix eggs. Two trials were run with breeders in their 8th month of production and one trial with breeders in their first month. After gathering from mass-mated pens consisting of 30 females and 10 males, the eggs were weighed individually and sorted into half gram classes.

Heritability of Egg Production and Egg Weight in Turkey
Abstract ALTHOUGH the inheritance of quantitative characters in chickens has been rather extensively investigated the measurement of genetic and environmental variances in turkeys has been largely neglected. Tacit assumptions that the magnitude of the genetic variability relative to the total variability is of the same size for analogous characters ...
