Effect of selection for plasma corticosterone level and feed conversion ratio in dwarf White Rocks on adaptability to hot temperature during growth



Effect of selection for plasma corticosterone level and feed conversion ratio in dwarf White Rocks on adaptability to hot temperature during growth



Archiv fuer Tierzucht 38(5): 503-511



High temperature impede the performance of birds under tropical condition. In the present investigation, it was analyzed howfar selected lines for plasma corticosterone level and feed conversion ratio of dwarf White Rocks respond to higher temperature during growth. Under high temperature condition (above 30 degree C), growth of all lines was reduced, however, in the feed conversion lines lowest reduction was noted. Carcass composition was not affected due to high temperature, but in some cases, pH-value of the thigh muscle was increased. The immune response to sheep erythrocytes was not affected. Acute heat stress induces a strong fall of leucocytes count. All the available datas indicate that genotype x ambient temperature interactions are of little consequence.
