The invention discloses an antibiotic-free feed for improving the production performance of weaned piglets and a preparation method thereof. The antibiotic-free feed comprises the following components by weight: 20-50 parts of corn, 5-15 parts of puffed corn, 5-15 parts of puffed soybeans, 5-15 parts of enzymatically hydrolyzed soybean meal, 2-10 parts of soybean meal, and 1-5 parts of fish meal , 1-5 parts of whey protein concentrate, 10-20 parts of whey powder, 1-5 parts of yeast extract, 1-5 parts of soybean hull, 1-3 parts of soybean oil, 1-5 parts of sucrose, 0.1-0.4 parts of salt parts, calcium hydrogen phosphate 0.4-1.0 parts, lysine hydrochloride 0.10-1.00 parts, methionine 0.01-0.20 parts, threonine 0.01-0.40 parts, zinc oxide 0.05-0.18 parts, choline chloride 0.10-0.30 parts , 1 part of premix. The preparation method of the antibiotic-free feed is obtained by mixing the raw materials in two steps and then granulating. The antibiotic-free feed of the invention has balanced nutrition, strong palatability, easy digestion, and improves the immunity of weaned piglets. Feeding this feed can significantly increase the feed intake of weaned piglets, improve the growth rate of weaned piglets, reduce the diarrhea rate and mortality rate of piglets, and thus improve the growth performance of weaned piglets. |
