Effect of rice distiller dried grains with solubles (RDDGS) in commercial broiler chicken ration on carcass traits, chemical composition, and fatty acid profile of meat

Abstract

A six-week experimental trial was conducted to evaluate the effect of feeding different levels of RDDGS in commercial broiler chicken on carcass traits, chemical composition, and fatty acid profile of meat. A total of 144 birds were divided into four treatments and three replicates each with 12 birds and were fed with RDDGS at inclusion levels of 0% (T1), 5% (T2), 10% (T3) and 15% (T4). All the rations were nearly isocaloric and isonitrogenous. One male and one female were selected from each replicate to determine the carcass traits and cut up parts. The meat samples were analyzed for its chemical composition and fatty acid profile. Statistical analysis of the data revealed that there was highly significant difference in the live body weight before slaughtering between T3 (10%) and T4 (15%) group when compared to control group, and there was no significant difference between the T1 (control) and T2 (5%) group in carcass characters and cut up parts. Intestinal length in males was significantly higher than females irrespective of the treatment. The fatty acid profile and chemical composition of meat were non-significant. So, it can be concluded that RDDGS could be included up to 5% without adverse effects on carcass traits and meat quality.
