Microbial fermenting feed for nursery pigs and preparation method thereof

Abstract

The invention discloses a microbial fermenting feed for nursery pigs. The microbial fermenting feed is prepared from the following components in percentage by mass: 15 to 25% of rapeseed stalk, 68 to 80% of cassava, 0.2 to 0.4% of pulsatilla chinensis, 0.1 to 0.3% of microorganism strain, 0.1 to 0.2% of cellulose, and 4.5 to 6.2% of salt. A preparation method comprises the following steps of pretreating the rapeseed stalk and the cassava, crushing, adding the microorganism and the cellulose, gradually stirring and uniformly mixing, packaging, and fermenting, so as to obtain the microbial fermenting feed. The microbial fermenting feed has the advantages that the crude fiber can be effectively degraded, the macromolecular matters in traditional Chinese medicine can be decomposed, the content of effective ingredients in the traditional Chinese medicine is increased, the bioavailability is improved, and the absorbing utilization rate is improved; the content of protein in the fermenting feed is improved, multiple types of organic acids, probiotics and the like are produced, and the palatability of the feed is improved; the nutritional stress diarrhea and common diarrhea diseases of digestion tracts in the nursery pig stage are prevented and controlled, the survival rate and daily weight increase rate of the nursery pig are increased, the feed and meat ratio is reduced, and the like; the feed can be used for the nursery pig in the whole process, and can be used for replacing 50% of complete feed of the nursery pig.

Description

technical field [0001] The invention belongs to the technical field of breeding feed, and in particular relates to a micro-storage fermented feed for nursery pigs and a preparation method thereof. Background technique [0002] Nursery pigs are commonly known as weaned piglets. The feeding of nursery pigs is one of the important links in pig production. The growth status of nursery pigs is directly related to the growth of the fattening period. Nursery pig death and growth slowdown caused by weaning stress have become an important factor restricting the development of pig industry. Because the digestive system, enzyme system, and autoimmune system of nursery pigs are still underdeveloped, they are highly susceptible to diseases, and are prone to weaning syndrome with physiological dysfunction such as diarrhea and growth stagnation. In severe cases, piglets will die, resulting in piglets. The slaughter rate is low. Therefore, if this stage is not well controlled, it will ser...

Problems solved by technology

Because the digestive system, enzyme system, and autoimmune system of nursery pigs are still underdeveloped, they are highly susceptible to diseases, and are prone to weaning syndrome with physiological dysfunction such as diarrhea and growth stagnation. In severe cases, piglets will die, resulting in piglets. The slaughter rate is low

Therefore, if this stage is not well controlled, it will seriously affect the quality of pork and the amount of slaughtered pigs

[0003] At present, due to changes in the breeding environment and refueling of most large-scale nursery pigs in China, intestinal diseases frequently occur in nursery pigs, and the mortality rate accounts for about 10%. piglet survival rate and slaughter rate

Currently, the nursery pig feeds on the market are mainly high-protein full-price feeds. Some manufacturers add some antibiotics or anti-diarrhea microecological preparations to the feeds, but the effect is not obvious, and it will cause the intestinal flora of sows to be disturbed. It cannot be absorbed and will burden the intestines

And the use of commercially available feed raw materials (corn, bean cake, rice) is likely to cause a vicious cycle of competition between humans and animals for food
