Organic-selenium-rich pig feed and preparation method thereof and breeding method

Abstract

The invention belongs to the technical field of pig breeding and discloses organic-selenium-rich pig feed and a preparation method thereof and a breeding method. The organic-selenium-rich pig feed isprepared from 40%-62% of corns, 5%-24% of wheat bran, 5%-15% of wheat flour, 5%-10% of probiotic fermented straw powder, 10%-25% of fermented oilseed cakes, 5%-10% of dried sweet potato powder, 100mg / kg-300mg / kg of organic selenium, 15%-25% of forage grass powder, 2%-15% of low-salt fish meal, 0.3%-0.7% of calcium gluconate and 0.4%-0.8% of bamboo salt. The feed is easy to digest and capable of remarkably preventing and controlling outbreak diseases such as swine fever, preventing digestive tract diseases of pigs and killing parasites, pigs fed with the feed are energetic, active, great in appetite, excellent in digestive function, fast in growth and great in fur condition, a feed conversion ratio reaches 2.5-2.7:1, pork is controllable in heavy metal and pesticide residue content and freeof synthetic hormones and synthetic antibiotics, and daily gain is 0.5kg or more.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to a pork feed rich in organic selenium, a preparation method and a breeding method thereof. Background technique [0002] At present, the commonly used prior art in the industry is as follows: selenium is an essential trace element for humans and animals, and is closely related to the health of humans and animals. Selenium cannot be synthesized in the human body, and selenium deficiency can cause a series of diseases in humans and animals, such as human Keshan disease, osteoarthritis and white muscle disease in livestock, etc. Recent studies have found that low selenium is associated with cardiovascular disease, liver disease, related to the incidence of cancer. At present, at least 70% of the population in our country has insufficient selenium intake and malnutrition, and the best way for people to supplement selenium is to supplement natural organic selenium-ric...

AI Technical Summary

Problems solved by technology

[0006] (1) The purity of the current pig feed is only 98%, which contains a large amount of heavy metals and chemical toxic substances. Inorganic selenium is used to supplement selenium for pigs and produce selenium-enriched pork. It is difficult to produce pollution-free selenium-enriched pig feed and pollution-free rich organic selenium pork

[0007] (2) Pork produced with selenium-containing pig feed currently available on the market is not only unsafe, but also has a strong fishy smell and is unpalatable

[0008] (3) Synthetic additives added to existing commercial feeds, such as antibiotics, synthetic growth hormones and other chemical additives, will cause damage to the health of pigs, reduce the immunity of pigs, and easily cause large-scale outbreaks of swine fever

[0009] (4)) The existing commercial feed production technology and raw material quality and product storage technology are backward, and the feed mycotoxins seriously exceed the standard, and no pollution-free selenium-enriched pig feed and pollution-free organic selenium-rich pork can be produced.
