Abstract

Raju, M.V.L.N., Rama Rao, S.V., Prakash, B., Paul, S.S. and Kannan, A. 2023. Effect of dietary inclusion of rice-distillers dried grains with solubles on performance and nutrient retention in laying chickens. Animal Nutrition and Feed Technology, 23: 1–12.

The feeding value of rice-based distillers dried grains with solubles (r-DDGS) was evaluated in the diet of laying chickens. A total of 4752, 24-weeks old laying chickens were divided at random into three groups having 18 replicates consisting of 88 birds in each. The experimental diets were compounded to contain r-DDGS at graded levels (0, 7.5 and 15.0%) on iso-caloric and iso-nitrogenous basis and each of the diets was fed to chickens from 24 to 47 weeks of age. Rice-DDGS at 15% in diet significantly (P<0.05) depressed the egg production, increased the feed intake and decreased the feed efficiency, whereas no such effect was observed at 7.5% r-DDGS level. The egg weight decreased with both levels of r-DDGS, but egg mass (g/bird/period) decreased only at 15.0% level of r-DDGS. Egg shell thickness and egg shell percentage were not affected, while mortality increased with r-DDGS in a dose dependant manner. Nutrient retention (dry matter, energy and nitrogen) was significantly (P<0.05) low at 15.0% r-DDGS. It is concluded that, r-DDGS at 7.5% in diet showed no adverse effects on egg production, feed conversion efficiency and egg mass in laying chickens.
