Estimation of Shell Weight and Shell Thickness from Egg Specific Gravity and Egg Weight

Poultry Science, 1982
Abstract Egg weight (EW), egg specific gravity (SG), shell thickness (ST), and shell weight (SW) were determined individually for 1853 eggs ranging in weight from 41 to 70 g. The eggs were laid by three groups of Single Comb White Leghorn (HN SW (g) = −5.972 + .06586 × SG + .09906 × EW (r2 = .890); SWUSA (mg/cm2) = 30.670 + .9565 × SG + .4571 × EW ...

Partitioning of the response to protein between egg number and egg weight

British Poultry Science, 1988
1. Data from published trials with laying hens were examined to see whether the concentration of dietary protein needed to achieve maximum egg weight was greater than the amount needed to achieve maximum rate of lay. 2. It is concluded that both rate of lay and egg weight continue to show small responses up to the same level of protein (or limiting ...

Relation of Avian Egg Weight to Body Weight

The Auk, 1975
JUST over 50 years ago Heinroth (1922) published the first extensive list of egg weights and adult body weights for 427 species of birds. Since then additional data have appeared and the most extensive list can now be found in Schonwetter's (1960-72) monumental description of bird eggs.

The effect of variation in egg numbers, body weight and egg weight upon shell thickness

British Poultry Science, 1972
Synopsis It is expected that when birds consume a diet with a fixed calcium content variation in the rate of egg production, in body weight or in egg weight will lead to variation in calcium consumption. This analysis investigated whether, in a particular experiment, this also led to variation in egg shell thickness.

The relationships between egg weight and yolk weight

British Poultry Science, 1964
Synopsis Figures on egg weight and yolk weight from a commercial strain of White Leghorn pullets obtained during the early part of their laying year have been analysed to obtain estimates of heritability and phenotypic, genotypic and environmental correlations.

The effects of egg weight on the hatching characteristics of ostrich eggs

2002
This research was carried out with the aim of determining the effects of egg weight on the hatching characteristics of ostrich eggs The effect of egg weight (small 1200 1400 g medium 1401 1600 g large >1600 g) on the hatchability of fertile eggs and hatchability of total eggs was found to be significant ...
