The invention discloses an antibiotic-free piglet feed and a preparation method thereof, and belongs to the fields of formula design and
processing technologies of feeds. The feed is mainly prepared from, by weight, 50-60 parts of corn, 2-4 parts of steamed
fish meal, 10-16 parts of
soybean meal, 1-5 parts of puffed soybeans, 3-5 parts of
wheat flour, 3-6 parts of whey
powder, 0.5-1 part of
coconut oil, 0.5-1 part of
soybean oil, 0.02-0.03 parts of antibacterial peptides, 1-3 parts of probiotics, 0.012 parts of
Yucca smalliana
Fern. extract, 0.3-0.7 parts of stone flour, 0.3-0.5 parts of edible salt, 0.8-1.2 parts of
calcium hydrogen phosphate, 0.3-0.8 parts of amino acids, 0.03-0.05 parts of compound
enzyme, 0.3-0.4 parts of composite vitamins and 0.2-0.6 parts of composite trace elements. The feed meets antibiotic-free piglet daily ration
nutrient standards, adopts the antibacterial peptides to substitute
antibiotics, and comprehensively solves problems through adding the probiotics, the daily
gain is increased by 6.17%, the average daily feed intake is increased by 5.38%, and the
diarrhea rate is reduced by 8.72%. The feed makes the intestinal tracts of piglets have good health state, has high
disease resistance, and lays an early foundation for early slaughtering, no medication and safe pork products.
