Impact of Dietary Inclusion of Rice Distillers Dried Grains with Solubles (DDGS) on Biochemical Parameters of Commercial Broilers

Abstract

An experiment was conducted to assess the effect of dietary inclusion of rice-derived distillers dried grains with solubles (DDGS) on the biochemical parameters of commercial broiler chicks. A total of 2250 day-old broiler chicks were randomly allocated into nine treatment groups and sub-divided into five groups to serve as a replicates. The control group was fed with basal diet formulated to meet all nutrient requirements, (as per the Beuro of Indian Standard) while the experimental diets included rice DDGS at progressively increasing levels, starting from 0% and increasing by 2% increments across treatments. At the end of sixth week, blood samples were collected from one bird per replicate for biochemical analysis. The results revealed that serum globulin, glucose, total serum sugar, and Serum Glutamic-Pyruvic Transaminase (SGPT) levels were significantly influenced (P<0.05) by the inclusion of rice DDGS, indicating effect on metabolic and hepatic activity. However, no significant changes were observed in total serum protein, albumin, and Serum Glutamic-Oxaloacetic Transaminase (SGOT) values, result indicate that protein metabolism and liver function remained unaffected. Variations in biochemical responses may be attributed to differences in the quality, origin, and possible mycotoxin contamination of rice DDGS. Based on these findings, it can be recommended that high-quality rice DDGS, free from aflatoxins contamination, can be safely included up to 16% in broiler diets without adverse effects on key biochemical parameters.
