Effect of feeding broken rice and distillers dried grains with solubles in a flaxseed-based diet on the growth performance, production efficiency, carcass characteristics, sensory evaluation of meat, and serum biochemistry of broiler chickens

摘要

This study investigated the effect of broken rice and distillers dried grains with solubles (DDGS) in a flaxseed-based diet on the growth performance, production efficiency, carcass characteristics, sensory evaluation of meat, and serum biochemistry of broiler chickens. Six dietary treatments were formulated with no flaxseed in the first group (C), 10% in another five (T1, T2, T3, T4, and T5), and 20% broken rice, 40% broken rice, 5% DDGS, and 10% DDGS in the T2, T3, T4, and T5 treatment groups, respectively. Each treatment was allocated 6 replicates with 8 chicks in each at random. Treatment with 10% flaxseed and 10% DDGS was found to have a negative effect on broiler growth and efficiency to some extent, whereas broken rice had no such effect. Feed that included 10% flaxseed and 40% broken rice significantly reduced serum triglyceride and cholesterol. Serum antioxidant enzyme activities and malondialdehyde concentration were increased by 10% flaxseed feeding and were further increased by 5% as well as 10% DDGS addition, whereas broken rice had no effect on them. The present study concluded that 10% flaxseed and 10% DDGS feeding negatively affects broiler performance and serum antioxidant capacity but reduces serum triglyceride and cholesterol levels, whereas broken rice can be safely used as a 40% replacement alternative for corn in broiler diets.
