Feed for improving immunity of piglets and preparation method thereof

Abstract

The invention provides a feed for improving immunity of piglets and a preparation method of the feed, and relates to the technical field of feeds. The feed is composed of a basic fermented feed and additives, wherein the basic fermented feed is prepared from the following raw material in parts by weight: 20-30 parts of sorghum rice flour, 4-10 parts of wheat bran, 15-20 parts of corn flour, 5-10 parts of fermented soybean meal, 1-3 parts of white sugar, 5-10 parts of fish meal, 2-4 parts of table salt, 3-6 parts of bacillus subtilis liquid, 20-30 parts of water; wherein the additive is prepared from the following raw material substances in parts by weight: 10 to 18 parts of algae oil DHA micro-capsule powder, 1 to 3 parts of sodium alginate, 1 to 3 parts of cinnamyl aldehyde, 2 to 4 partsof mannan oligosaccharide, 5 to 10 parts of radix puerariae powder, 1 to 2 parts of perilla seed oil and 4 to 8 parts of slow-release probiotic freeze-dried powder. The feed for improving immunity ofpiglets can enhance immunity of piglets, relieve allergy, improve feed conversion rate, reduce breeding cost, promote growth and development, increase livestock and poultry yield and improve economicbenefits.

Description

Technical field [0001] The invention relates to the technical field of feed, in particular to a feed for improving the immunity of piglets and a preparation method thereof. Background technique [0002] Early weaning technology is widely used in modern intensive pig production. After piglets leave the sow, they are prone to slow growth and diarrhea due to sudden changes in the breeding environment and nutrition, re-combination, and establishment of a new hierarchical order. Early weaning stress syndrome is the main feature of piglets. Due to the high incidence and mortality of this disease, it has brought heavy losses to the pig industry. [0003] For a long time, people have relied on adding antibiotics and antibacterial drugs to the feed to prevent piglet diseases. However, with the extension of the medication time, the resistance of pathogenic microorganisms has become stronger, the amount of drugs used has increased, and the disease prevention effect has become more and more. ...

Due to the high morbidity and mortality rate of this disease, it has brought significant losses to the swine industry

[0003] For a long time, people have relied on adding antibiotics and antibacterial drugs to feed to prevent piglet diseases. However, with the extension of drug use time, the resistance of pathogenic microorganisms is getting stronger and stronger, and the dosage of drugs is increasing, and the effect of disease prevention is getting better and better. Poor and costly

Moreover, antibiotics and antibacterial drugs used in large quantities will form residues in pigs, making pork unsafe to eat, and excrement with drug residues has also caused serious impacts on the ecological environment and has become a serious social problem
