Efficiency of rendered chicken oil and coconut oil as feed binders towards the growth performance of the broiler at grower stage

The nutrients in feed and the feed compositions may affect the palatability and digestibility of the feed and also influence the performance of the livestock including
the body weight gain. The poultry by-product such as the rendered chicken oil and also the coconut oil has been utilized as another alternative as the feed binder for lowering the feed cost and conserving the environment. Therefore, the present study was conducted to investigate the efficiency of rendered chicken oil and coconut oil as feed binders towards the growth performance of the broiler at the grower stage. The animal feed trial was conducted at Agrotechnopark, Universiti Malaysia Kelantan (UMK), Jeli
Campus. 198 broilers were selected and randomly assigned to 3 different dietary groups. The broilers were fed with palm oil (control), feed that had been supplemented with coconut oil (treatment 1) and rendered chicken oil (treatment 2) as the feed binders. The feeds were analyzed for the determination of the physical (texture profile and colour analysis) and chemical (proximate analysis). Meanwhile, the growth of the broilers was monitored from week 3 until week 5 in terms of the increment of the body weight. The hardness of the feed range from 15.67 to 85.67 (g) and the springiness of meat range from 0.36 to 0.48 (mm). The dry matter of the feeds in the range between from 89.99 to 95.12%, the crude protein range from 17.02 to 21.01%, the crude fat range from 5.60 to 6.25% and the ash content range from 4.20 to 5.26%. There are differences in term of the weekly body weight gain of the broilers after being fed with
different feeds. In conclusion, the composition of fat that added to feed affect the growth rate on broiler chicken.
