    Broiler üretiminde değişik yerleşim sıklığı ve kesim yaşlarında büyüme ve ekonomik verimlilik
    (Uludağ Üniversitesi, 1995) Oğan, Mustafa; Veteriner Fakültesi; Zootekni Ana Bilim Dalı
    This study was done to put forward the growth performance of commercial broiler hybrids in various stocking densities and slaughter ages and to determine the economical density. The study was performed in Uludağ University Faculty of Veterinary Medicine Research and Application Farm. 2880 Arbor Acres chicks were used as study material. Chicks were grown in four different stocking densities (10, 14, 18 and 22 chicks per square meter) and slaughtered in three dfferent slaughter ages (in the 5th, 6th and 7th weeks). In the 5th,6th and 7th weeks living weights and carcass weights were found similiar in groups with stocking densities 10 and 14 birds/m2 and they were found much higher than the values gained in groups with higher stocking densities (18 and 22 birds/m2). Male chicks grew more quickly than females in all periods and stocking densities. In the 6th and 7th weeks, the best feed conversion was determined in groups with stocking densities 10 and 14 birds/m2. From the aspect of survival rate no important difference was found in groups with various stocking densities. Economic analyses indicated that profit gained per square meter increased as the stocking density increased. Maximum profit per square meter was determined in the group with density 22 birds/m2. It was convinced that the 6th week would be convenient as the slaughter age.
