Antibiotic-free feed for nursery pigs and preparation method thereof

Abstract

The invention discloses an antibiotic-free feed for nursery pigs and a preparation method thereof. Corn, barley and soybean meal are pre-cleaned to remove impurities and enter a permanent magnet drum to remove tramp iron; the materials enter a bin for smashing respectively; smashing is performed, 100% of smashed materials are subjected to 14-mesh sieving, and 95% of the smashed materials are subjected to 20-mesh sieving; suckling pig compound enzyme, a vitamin premixing agent, a microbial ecological agent, plant essential oil, phagostimulant, high temperature resistant phytase, an organic microelement premixing agent, a Chinese herbal medicine prescription, yeast cell wall polysaccharide, glycerol monobutyralte and an emulsifier are firstly mixed fully for use; then the corn, the barley, the soybean meal, soybean oil, extruded soybeans, fermented soybean meal, import fish meal, whey mist, salt, calcium formate, calcium hydrophosphate, amino acid, composite organic acid, an antioxidant and a mildewproof agent are weighed in proportion and then are compounded and mixed; finally granulation is performed. An antibiosis growth promotion effect which is the same as or better than that obtained by using antibiotics can be achieved, the sensibility of germs to the antibiotics is improved, and the treatment drug effect is improved.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and relates to an antibiotic-free feed for nursery pigs suitable for nursery piglets at the age of 35 days to 60 days (body weight ranges from 10kg to 25kg) and a preparation method thereof. Background technique [0002] The continuous and stable development of my country's animal husbandry in the past two decades is inseparable from the great contribution of antibiotics. The long-term addition of antibiotics in feed, health care and therapeutic drugs in the production process has led to excessive use or even abuse of antibiotics in animal husbandry. Abuse of antibiotics will destroy intestinal microorganisms, lead to an imbalance of intestinal flora, inhibit the digestion and absorption of nutrients, be susceptible to pathogenic bacteria, reduce immune function, cause disease of the body, and affect its growth performance; at the same time, the residue and enrichment of antibiotics in animal pro...

Problems solved by technology

Abuse of antibiotics will destroy intestinal microorganisms, lead to an imbalance of intestinal flora, inhibit the digestion and absorption of nutrients, be susceptible to pathogenic bacteria, reduce immune function, cause disease of the body, and affect its growth performance; at the same time, the residue and enrichment of antibiotics in animal products , causing damage to the physiological functions of the human body, including disabling, sensitizing, teratogenic and genetically mutagenic effects, etc. Bacterial drug resistance has brought great difficulties to the chemotherapy of antibiotics and other drugs, affecting the therapeutic effect of antibiotics
