Poultry Husbandry Report
Heritability of egg size is approximately 60%-a very high value compared to the heritability of most other economic characters-and indicates that individual selection for egg size is to be preferred to family selection. A further simplification of the problem of changing the egg size of a flock by breeding selection is possible as a result of a study of genetic correlations between the weights ...
متن کاملThe Principles of Poultry Husbandry
There are a number of requirements by which animals should be managed so that the best performance is achieved in a way acceptable to those responsible for the care of the animals and to the community generally. These requirements are the keys to good management and may be used to test the management of a poultry enterprise in relation to the standard of its management. These requirements are a...

متن کاملBehavior Genetic Analyses in Chickens and Quail
Behavior-genetic analysis requries an interfacing of genetics and behavior. This may be accomplished by studying the genetic architecture of specific behaviors and by examining how behaviors influence selection and thereby modify the gene pools of subsequent generations. The behaviors emphasized in our research include those associated with reproduction, feeding and social strife. This morning'...
