ABSTRACT
This study evaluated the productive performance and carcass characteristics of broiler chickens fed diets containing prilled fats of palm oil (PFPO) or calcium soaps of palm oil (CaSPO) replacing vegetable oils (VO). A total of two hundred 1-day-old male Ross 308 chickens were allocated in a 2 × 2 randomized factorial design. Diets included 2 PFPO levels (0 and 50%) and 2 CaSPO levels (0 and 50%). The level was the percentage of substitution of VO by granulated fats. The study had two phases (starter and finisher), each lasting 21 days. In the starter phase, PFPO did not influence (main effects; p>0.05) feed intake and body weight gain, but improved (main effect; p=0.03) feed conversion. In the finisher phase and the total study, PFPO had no effect (p>0.05) on these productive variables. Throughout the study, CaSPO did not influence feed intake (main effect; p>0.50), but decreased weight gain and had a negative effect on feed conversion (main effects; p<0.05). There was no influence of fats (PFPO or CaSPO) on carcass yield, breast, drumsticks plus thighs, and wings (main effects; p>0.05). Chickens fed CaSPO had lower (main effect; p=0.02) carcass weight. The only PFPO × CaSPO interaction (p=0.04) was for back yield. Results showed that PFPO or CaSPO could be employed in formulating broiler chicken diets, as they are less expensive than conventional VO. Partial substitution of VO for PFPO had minimal effect on productive variables, although partial dietary inclusion of CaSPO might slightly reduce the production of broiler chickens.(AU)
