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 additi

preparation example Construction

[0064] Such as figure 1 Shown, the preparation method of the pig feed rich in organic selenium that the embodiment of the present invention provides comprises the following steps:

[0065] S101: Put pork feed raw materials rich in organic selenium in an ozone sterilized self-controlled constant temperature solid fermenter to sterilize and degrade mycotoxins with ozone, and blow the ozone in the tank out of the fermenter with sterile air output from a sterile air compressor ;

[0066] S102: In a sterile environment, add 5% to 50% of the weight of the raw material to the raw material that has been depleted of ozone, such as Bacillus Velez, Candida tropicalis, Bacillus subtilis, Bacillus amyloliquefaciens, etc. Mix the fermented liquid in large quantities, and add sterile water to adjust the water content of the fermented product to 20% to 40%, degrade mycotoxins by aerobic fermentation, degrade proteins into small molecular peptides and amino acids, and degrade starch into smal...

Embodiment 1

[0070] Embodiment 1: 20kg~25kg fattening early stage pig weaned piglet rich in organic selenium feed and breeding method;

[0071] (1) Feed raw materials: 40-62% of corn with heavy metals and pesticide residues not exceeding the standard, 5-10% of wheat bran, 5-15% of wheat flour, 10-15% of dry cake fermented with probiotics, 2-5% of dry sweet potato powder Containing organic selenium 30-50mg / kg forage powder 5-10%, straw powder 0.2-1%, low-salt fish meal 10-15%, calcium gluconate 0.4-0.8%, bamboo salt 0.3-0.5%.

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...
