Microbial fermentation antibiotic-free feed for lactating sow

Abstract

The invention discloses microbial fermentation antibiotic-free feed for a lactating sow. The feed is obtained by mixing a mixture and a prepared fermentation material, wherein the weight ratio of the mixture to the prepared fermentation material is (92-96):(4-8); and the prepared fermentation material is prepared from the following fermentation materials in parts by weight: 2-5.5 parts of lactobacillus acidophilus fermentation material, 0.05-0.1 part of bacillus subtilis fermentation material, 1.00-1.90 parts of saccharomyces cerevisiae fermentation material, 0.05-0.1 part of trichoderma longibrachiatum fermentation material, 0.05-0.2 part of aspergillus niger fermentation material and 0.05-0.2 part of aspergillus oryzae fermentation material. Through the invention, the use of antibiotic drugs in the lactating sow feed can be avoided, the micro ecological environment of the intestinal tract of the lactating sow as well as the immunity are obviously improved, the breeding stress of the sow and the birth stress of the piglets are eased, the problems of constipation and milk lack of the sow are effectively solved, the morbidity is reduced, the feed intake and feed digestion utilization rate are improved, the piglet diarrhea rate is reduced, the survival rate is improved, and the birth weight and weaning weight of the piglets are obviously increased so as to improve the farming benefits.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to microbial fermentation antibiotic-free feed for lactating sows. Background technique [0002] The addition of antibiotics to feed in the 20th century has brought about the rapid development of the global animal husbandry industry. However, long-term feeding of animals with antibiotic-added feed will produce drug-resistant strains in the body and cause problems such as drug residues in animal products. With the gradual improvement of people's living standards, consumers' demand for livestock and poultry products has transitioned from the pursuit of quantity to the pursuit of quality, so the practice of adding antibiotics to feed is becoming more and more restricted. Currently, in Europe, North America, Asia and other regions Many countries have banned the addition of antibiotics to feed. [0003] The addition of antibiotics to lactating sow feed products has a number of adve...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a microbiologically fermented antibiotic-free feed for lactating sows in view of the existing problems caused by adding antibiotics to feed products for lactating sows. The microbially fermented antibiotic-free feed for lactating sows is rich in beneficial Live bacteria, polysaccharides, antimicrobial peptides, digestive enzymes, organic acids and growth-promoting factors, etc., so it is beneficial for lactating sows to eat, digest and absorb, and can improve the health of sows and improve the health status of sows without adding antibiotics.
