Broiler Chickens Performance as Affected by Animal Fat and Plant Oil under Hot Arid Conditions of Sudan

Peanut oil, Beef tallow, Broiler, Performance, SudanAbstract
The influence of dietary animal fat and plant oil on broilers performance under Sudan conditions was studied. The experiment lasted seven weeks. One hundred and fifty one - day old, unsexed Lohmann breed chicks were divided randomly into three dietary treatments (50 birds /treatment) with five replicates of ten birds each. Average minimum and maximum temperatures during the experimental period were 26.1â—¦ C and 38.9 â—¦C, respectively. Parameters measured were feed intake, body weight gain, feed conversion ratio, and mortality rate.
Three dietary treatments were used in this study. Diet A with no fat added ( NF) , diet B was supplemented with 5% peanut oil ( PO )  and in diet C 5% beef tallow ( BT) was added . The three diets were made to be isonitrogenous. All nutrients were calculated to meet the USA National Research Council Requirements (NRC, 1984) for broiler chicks.
The results indicate that during the experimental period feed consumption was not affected by fat addition, irrespective of its source. There was a trend to increase the total body weight gain but the difference did not reach significant level. It was noticed that the ambient temperature during the experiment was very high which might upset the beneficial effect of dietary fat.
