Fermented feedstuff preparation for piglets as well as preparation method and application thereof

Abstract

The invention discloses a fermented feedstuff preparation for piglets as well as a preparation method and application thereof, and aims at providing a fermented feedstuff preparation with carbohydrates, crude proteins, amino acids, crude fibers, digestible energy, phosphorus, calcium, trace elements and the like meeting the physiological and nutritional requirements of the piglets. The technical scheme is as follows: the fermented feedstuff preparation for the piglets comprises the following raw materials in parts by weight: 90-95 parts of corn, 62-68 parts of soybean meal, 55-60 parts of cottonseed meal, 55-60 parts of rapeseed meal, 45-50 parts of bran, 40-45 parts of peanut meal, 40-45 parts of cassava residue, 30-35 parts of pine needle meal, 20-25 parts of myrtle leaves, 15-20 parts of kelp powder, 15-20 parts of medical stones and 2-5 parts of molasses. The invention belongs to the technical field of feeds.

Description

technical field [0001] The invention relates to a pig feed, in particular to a special fermented feed raw material preparation for piglets, which belongs to the technical field of feed. Background technique [0002] When suckling piglets are born, there is only rennet and little pepsin in the stomach. Because the fundic glands are underdeveloped, they lack free hydrochloric acid and pepsin, have no activity, and cannot digest vegetable protein. At this time, only the intestinal glands and pancreas are relatively fully developed, and the activities of trypsin, intestinal amylase and lactase are relatively high, and food is mainly digested in the small intestine. Therefore, piglets from birth to about a week can only eat milk, and can gradually digest and utilize plant feed after a week. The type and amount of flora in the intestinal tract of newborn piglets are very small and very unbalanced, so it is very unfavorable for the absorption and utilization of nutrients; and the ...

AI Technical Summary

Problems solved by technology

Every year, my country needs to spend a large amount of foreign exchange to import more than 30 million tons of soybean meal and other vegetable protein raw materials, and a large number of by-products of agricultural product processing in my country, such as rapeseed meal, cottonseed meal, bran, peanut meal, cassava residue, sugarcane molasses, etc. underutilized

Due to the presence of trypsin inhibitors, urease, prothrombin, glycinin, β-conglycinin, phytic acid, soybean antigens or glucosinolates and their products, free gossypol in soybean meal, rapeseed meal, cottonseed meal and other raw meals On the one hand, their existence inhibits certain digestive enzymes in animals, and combines with nutrients to form indigestible components, which reduces the digestibility of raw meal and the absorption rate of animals; Some organs in animals cause damage, causing adverse effects on animal physiology, growth, and health, and restricting the large-scale use of cottonseed meal, rapeseed meal, etc. in feed
