Nutrient digestibility of wheat wet and dried distillers' grain in growing pigs

摘要: The research was conducted to evaluate ileal and total tract digestibility of crude protein (CP), organic matter (OM) energy in growing pigs supplied with dietary inclusion commercially available wheat wet distillers grain solubles (WWDGS) dried distillers’ (WDDGS). Seven castrated male post valve t-caecum (PVTC) cannulas an average initial body weight 79 kg were fed two experimental diets (W D) a change-over design. Diet W composed 50% WWDGS basal diet, diet D WDDGS diet. corn starch, sugar, premix titanium dioxide. A casein-based prior after the study estimate endogenous nitrogen amino acid (AA) losses. Apparent (AID) for CP higher (p 0.05) between diets. (ATTD) recorded digestibility. Endogenous losses each pig evaluated separately used calculation standardized (SID) AA. from pre- period 8.53±0.95 g/kg DM digesta. SID value CP, methionine lysine (p<0.05) than D. There significant increased variation WDDGS. Differences production plants chemical composition sources main reasons different nutritional values products. Despite excellent properties, low dry content, decreased P high transportation cost, limits use local area within reasonable distance factory.
