Abstract: A new variety of Dahe Black pig was independently nurtured at Qujing which was authorized by the National Genetic Resources Committee in 2003. Over the past ten-odd years, no one has done the research on protein nutritional needs of the Dahe Black pig in growing and fattening. In order to explore the requirements of protein nutritional of the Dahe Black pig in growing and fattening, we had growth and fattening test with different protein nutrition level feed from May to August, in 2015. The test divided into three groups of A, B, C;30~50 kg and 50~120 kg two stages; each group used one equipmen of "Osborn" which measuring the pig performance accurately, attened 10 Dahe Black pig (group A only 9 head after lost one in the test), under the premise of the basic consistency of the nutrition level, respectively used 16%, 14%and 12%protein nutritional levels at 30~50 kg stage of group A, B, C; r espectively used 14%, 12.5% and 11% protein nutritional levels at 50~120 kg stage. As a result, the best protein nutrition demand level of the Dahe Black pig in growing and fattening is 14% at 30~50 kg stage; the best protein nutrition demand level is 11% at 50~120 kg stage; the best protein nutrition demand level for fattening are 12% in the early stage (30~50 kg)and 11% in the later stage (after 50 kg) at 30~120 kg stage.Primary research the protein nutritional needs for Dahe Black pig in growing and fatten-ing period.
