Effects of dietary supplementation with rice bran oil on the growth performance, blood parameters, and immune response of broiler chickens

摘要

The objective of this experiment was to investigate the effects of dietary supplementation of rice bran oil (RBO) on growth performance, blood parameter, and immune response in broiler chickens. Methods A total of 240 1-d-old ROSS 308 male broilers were randomly allotted to 4 dietary treatments with six replicated pens consisting of ten chicks. The basal diet was formulated to be adequate in energy and nutrients. Three additional diets were prepared by adding 5, 10 or 20?g/kg of RBO to the basal diet. The experimental diets were fed on an ad libitum basis to the birds during 35 d. Results Results indicated that increasing inclusion level of RBO in diets improved BW gain (linear and quadratic, P Conclusions These results suggest that dietary RBO may be used functional ingredient to improve growth performance, total cholesterol in serum, and immune response of birds.
