GENETIC EVALUATION OF TWO SYNTHETIC LINES
(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2005-11) JOMON JOSEPH; K.S. PRATHAP KUMAR; H.N.NARASIMHA MURTHY
Poultry is one of the fastest growing industry and the demand for good quality meat and egg is ever increasing. Poultry meat is a well-balanced source of animal protein and has no religious taboos associated with its consumption unlike meat of other livestock; hence it’s gaining more and more importance in the human diet. Selection is the most important tool for achieving genetic improvement in poultry, when relative efficiency of different selection methods are compared multi trait selection is most effective when several interlinked, economically important traits are involved. Breeders are interested in increasing the meat yield of the broilers and improving the appearance of the carcass. Previously the body weight at 8‘h week of age was considered as important trait in broilers but now its consideration is switched to and 6^^ week’s body weight. The body conformation parameters such as keel and shank length, breast width, breast angle are good indicators of skeletal size and can be used as genetic parameters for broiler improvement. Introduction of growth traits in selection along with feed efficiency and conformation traits is expected to give better results than selection based on growth traits alone (Mishra et ah, 1986).
