Abstract

The invention discloses an antibiotic-free environment-friendly low-protein piglet nursing material and a preparation method thereof. The nursing material is mainly prepared from the raw materials of,by mass, 10 to 40 parts of corn, 10 to 35 parts of puffed corn, 5 to 25 parts of broken rice, 10 to 25 parts of enzymolyzed soybean meal, 1 to 5 parts of yeast extract, 5 to 20 parts of whey powder,1 to 3 parts of soybean oil, 0.5 to 1.2 parts of calcium hydrophosphate, 0.3 to 0.6 parts of acidifier, 0.5 to 1.2 parts of stone powder, 0.3 to 1.0 part of lysine hydrochloride, 0.1 to 0.5 part of methionine, 0.1 to 0.5 part of threonine, 0.01 to 0.1 part of tryptophan, 0.01 to 0.1 part of histidine, 0.01 to 0.1 part of phenylalanine, 0.1 to 0.3 part of valine, 0.1 to 0.3 part of isoleucine, 0.1to 0.3 part of table salt and 1 part of premix. The nursing material does not contain antibiotics, is low in protein, zinc and copper content, can remarkably reduce the diarrhea rate of weaned piglets, and improves the growth performance of weaned piglets.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to an antibiotic-free, environment-friendly low-protein nursery feed for piglets. Background technique [0002] With the development of pig production in the direction of scale and intensification, in order to improve the productivity of sows and the economic benefits of pig raising, the early weaning technology of weaning piglets at the age of 3-4 weeks is generally adopted in production. However, weaning at the age of 3-4 weeks usually produces early weaning stress, which leads to diarrhea and growth retardation within 1-2 weeks after weaning, which has a great impact on pig production. This problem has not been completely resolved so far. Typically, antibiotics or higher levels of copper and zinc (ZnO, CuO) are added to the diet for anti-diarrhea. [0003] However, antibiotic resistance caused by antibiotics, antibiotic residues in the food chain and other negative effects have att...
