EFFECTS OF TEMPERATURE AND ENERGY-PROTEIN RATION ON THE PERFORMANCE OF BROILER CHICKEN

Abstract

A study was conducted to investigate the effects of temperatures and energy-protein rations on performance of broiler chicken 3-6 weeks old. Three hundred twenty four 3 weeks old male lssavedet with the initial body weight of 574 1 5.86 g was housed in close house with pad and fan cooling system. The chicken was divided into three groups and each group was replicated 3 times as a one unit experiment. Each unit (hh0,6m) with litter floor system was consist of 12 chicks. Two factors of treatments are zone temperature and energy-protein ratio. Factor one were zone l (20-27°C), zone II (23-30°C) and zone III (26-33"C). Factor two were P1 (2900 kcal/kg and 20% CP), P2 (3100 kcal/kg and 21% CP) and P3 (3300 kcal/kg and 22% CP). The parameters were feed consumption (FC), body weight gain (BWG), feed conversion ratio (FCR), Carcass presentation (CCP) and abdominal fat contain (AFC). The data was analyzed with the ANOVA and if there is significant different between treatment, the analysis was continued by multiple range test of Duncan. The result was suggested that zone temperature and energy-protein ratio has effected to all parameters significantly (P<.05). However, it was no correlation between zone temperature and energy-protein ration on the performance of broiler chicken. This experiment can be concluded that pad and cooling system house has three different zone temperatures and it should be have different energy-protein ratio.
