    ECONOMIC IMPACT OF VARIATION IN DIETARY PROFILE AND DURATION OF EARLY FEED RESTRICTION IN BROILERS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2006-09) O.R. NATARAJU; K. S. Prathapkumar; B. Umakantha; H.N. Narasimhamurthy; B. S. Venkatarami Reddy
    Poultry production in the country has gained momentum during the last four decades. Consequently, it has taken the shape of full-fledged industry. At present, this industry has emerged as the most dynamic and fastest expanding segment in Animal Husbandry sector with an annual growth rate of 6 per cent in 1980s, 11 per cent in 1990s and 19 per cent in 1997-2002 in broiler chickens and 5 per cent in egg production. With an annual production of around 43.67 billion eggs and 1440 thousand metric tones of broiler meat, India ranks 4th and 5th respectively, in the world (Mandal et al., 2005). Poultry sector in India contributes 100 billion rupees to the Gross National Product (GNP). The annual per capita availability of 1 kg meat in India is lower than 10.8 kg meat recommended by National Committee on Human Nutrition (Evans, 2002). Hence, the industry has potential to grow at about 10 times in meat sector. Broiler meat has a greater demand as compared to other meats, primarily because of the limitations and religious taboos in case of beef and pork. It also has the highest acceptability among all sections of consumers.

    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).
