Piglet feed additive and preparation method and application thereof

Abstract

The invention relates to the technical field of feeds and discloses a piglet feed additive and a preparation method and application thereof. The additive is prepared from, by weight, 60%-70% of sproutseed coats, 25%-40% of edible mushroom stalks and 3%-5% of ginkgo leaves. By enzymolysis treatment of the sprout seed coats, the edible mushroom stalks and ginkgo leaf powder, stachyose and other active polysaccharides in materials are released substantially; by microbiological fermentation of the sprout seed coats, the edible mushroom stalks and ginkgo leaf powder, anti-nutrition components suchas trypsin inhibiting factors in the sprout seed coats are degraded completely; after fermentation is finished, drying and grinding are performed to obtain the piglet feed additive. The piglet feed additive has advantages that gastrointestinal health of piglets can be effectively improved, the diarrhea rate is remarkably decreased, and adding the piglet feed additive into feeds has remarkable effects in raising of the health level of pigs and reduction of antibiotic consumption.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed additive for piglets and a preparation method and application thereof. Background technique [0002] Soybean seed coat is a layer of material covering the surface of soybeans. In addition to obtaining a large number of by-product seed coats in soybean oil by using the peeling process, a large number of bean sprouts manufacturers are producing bean sprouts (such as soybean sprouts, mung bean sprouts, Red bean sprouts, pea sprouts, broad bean sprouts, black bean sprouts, etc.) also need to remove the seed coat, resulting in a great waste of resources. The main component of soybean hulls is fiber, which contains low lignin and relatively high protein content. Therefore, it is more suitable for animal feed than straw and forage. When it is used as animal feed, it can not only provide many Energy, and can improve digestibility and excretion; for ruminants, some fatty acids can be...

AI Technical Summary

Problems solved by technology

[0003] However, because the seed coats of sprouts contain anti-nutritional substances such as trypsin inhibitors, direct feeding to animals will have adverse effects on the growth of farmed animals; seed coats of sprouts and edible mushroom feet both contain more cellulose components, which are harmful to the growth of animals. The intestinal tract of immature piglets is not good; in addition, the use of ginkgo biloba on piglets has problems with the amount of use and treatment methods, which may cause problems such as diarrhea in piglets

[0004] To sum up, it can be seen that the ingredients in the above ingredients, when used alone or in combination, will not produce additive effects when used for farmed animals. Poor effect or even diarrhea, slow growth and development, etc.
