Abstract

The invention relates to a piglet low-protein feed, in particular to a piglet low-protein feed with lower protein content. The piglet low-protein feed comprises the following compositions in portions by weight: 30-40 portions of corn, 25-35 portions of puffed corn, 2-4 portions of imported fish meal, 10-15 portions of dehulled soyabean pulp, 4-8 portions of enmolysis soyabean pulp, 2-6 portions of whey powder, 1-3 portions of soyabean oil, 1-2 portions of calcium hydrophosphate, 0.1-1 portions of mountain flour, 0.2-0.6 portion of lysine, 0.1-0.4 portion of methionine, 0.05-0.2 portion of threonine, 0.01-0.1 portion of tryptophane, and 2 portions of premixing compound. The invention reduce the use of protein raw materials during the preparation of the feed, and supplements crystal amino acid, thereby balancing the level of the amino acid in the feed, relieving the problem of lacking the protein raw materials on the premise of meeting the demand of piglets to a certain extent, lowering the feed cost, reducing the environmental pollution of a farm, and reducing the diarrhea of the piglets.

Description

【Technical field】 [0001] The invention relates to a feed for piglets, in particular to a feed for piglets with low protein content. 【Background technique】 [0002] The protein content of the existing feed for piglets is generally about 19%. Because the protein content is higher, the cost of the feed is increased to a certain extent. Currently, China’s pig feed generally uses corn and soybean meal-based feed. Due to the high price of soybean meal and the shortage of resources, it is highly dependent on imports. The high protein content in piglet feed leads to a shortage of protein resources such as soybean meal. more grim. Moreover, the high protein content in piglet feed makes piglets feces and urine nitrogen, especially urea nitrogen in urine, high, and the pollution of water resources in excreted waste piles is relatively large. Often fed such feeds, piglets' limited acidifying capacity leads to lower acidification of high-protein feeds, and the proliferation of pathogen...
