Possibilities of Inclusion of corn Distillers Dried Grains with Solubles (DDGS) alone or in combination with Probiotic as Broiler Feed Ingredient

In the production of the ethanol from cereal grains, besides the main product which is ethanol, there are olso very valuable by-product that can be used as animal feed. The dried distilled grains with solubles (DDGS) is quite rich in protein and other nutrients. With the ever-increasing cost of soybeans and corn, many scientists are studying the possibilities of using DDGS in poultry nutrition. The aim of the present study was to determine the effect of including corn DDGS and corn DDGS and probiotic in compound feeds on productive, slaughter performance and some meat physicochemical parameters of broiler chickens under floor-rearing conditions. The experiment included 3 treatments (T), namely T1: the control group received a balanced compound feed, according to the requirements of the hybrid, without the participation of corn DDGS, T2: the diett contained 15% corn DDGS and T3: the dietts contained 15% corn DDGS and supplemented 500g probiotic/ton of feed. Each experiment had 20 one-day-old sexed male Ross-308 broiler chickens, replicated 3 times, and ended when the chickens were 35 days old. The results shown that diets T2 and T3 did not positively affect the weight development of chicks compared to T1 (the control group). At 35 days old, chicken weight from the control group outperformed the two experimental groups: by 8.45% in the T3 (corn DDGS and probiotic) and by 11.76% in the T2 (corn DDGS) at P<0.05. Differences in feed consumption per 1 kg of growth over the 35-day fattening period between the control and experimental groups were small and statistically unproven. Feeding diets with 15% DDGS from corn significantly reduced carcass weight, grill, thight and wing weight in broiler chickens. There were no significant differences in slaughter yield between the study groups. Diets T2 and T3 improved the water holding capacity (WHC %) of breast meat in broilers (at P< 0.001). The lowest loss in thermal processing (cooking) was observed in breast and thigh meat of chickens fed the diets with 15% corn DDGS and probiotic (P<0.05).
