Production Performance of Broiler Chickens Fed Glucogenic and Lipogenic Diets to Overcome Environment Temperature

Abstract

Two types of diet, glucogenic and lipogenic, were equally tested to 24 broiler chicken in completely randomized design for four weeks to evaluate their effects on body weight, feed intake, feed conversion ratio (FCR), carcass, and whole carcass weight. Diets were designed to contain 1.05% and 7.0% of palm oil, as glucogenic and lipogenic ones, respectively. Both diets were formulated as isoprotein (22%) and isocaloric (3050 kcal/kg) to overcome the environment temperature of 25.8- 30.40C, around the poultry housing at campus. The birds were weighed at the beginning, weekly, and at the end of the diet application. The difference of these body weights were calculated as body weight gain (BWG). Feed intakes were accumulated weekly to the end. The FCR was calculated as the ratio of feed intake to body weight gain. Carcass and whole carcass were then compared to their body weight gain for each diet. Results showed that even though there were no significant differences (p>0.05), however, BWG in glucogenic diet chicken were 2.3% higher than that of in lipogenic diet birds. While, the feed intake in lipogenic diet chicken were significantly higher (p<0.05) than that of in glucogenic diet birds. Accordingly, the FCR was also significantly higher (p<0.05) in lipogenic diet of broiler chicken. None of carcass variables was significantly different, however, the glucogenic diet birds were 10.6% heavier than that of the lipogenic diet birds. Having higher in BWG, carcass weights, and carcass ratios, yet, lower in Feed intake and FCR, it can be concluded that glucogenic diet fed to broiler chickens was more efficient in overcoming the environment temperature, therefore the production performance was better than that of lipogenic diet
