Abstract

The invention discloses a microorganism feed supplement for lowering the stress of piglets and a preparation method thereof. The preparation method comprises the specific steps of fermenting bacillus subtilis, lactobacillus plantarum and saccharomyces cerevisiae with a medium and raw materials such as sterile water, carrying out spray drying on fermentation liquor, then mixing with a protective agent so as to prepare the finished product. The preparation method has the characteristics that the production is simple, the raw materials are easy to obtain, and the production cost is low; the feed supplement can improve the antioxidant ability of early weaned piglets, improve the antioxidant ability of hepatic cells of piglets, lower the stress reaction of early weaned piglets and transferred piglets, reduce intestinal tract and respiratory diseases, and lower the diarrhea rate of early weaned piglets, so that the daily gain of the early weaned piglets is improved and increased, the feed conversion efficiency is improved, and the anti-stress ability of the piglets is improved comprehensively.

Description

technical field [0001] The invention relates to a microbial feed additive, in particular to a microbial feed additive capable of reducing piglet stress and a preparation method thereof. Background technique [0002] Newborn piglets have physiological characteristics such as fast growth and development, poor temperature regulation ability, poor immunity, underdeveloped digestive organs, unsound digestive enzymes, and insufficient gastric acid secretion. In the current intensive pig production, early weaning of piglets is one of the key technologies in pig farming. Early weaning of piglets can increase the reproductive rate of sows, reduce the transmission of diseases from mother to piglets, and improve production performance and carcass quality during the growth period. [0003] At present, developed countries in the foreign pig industry have begun to promote the application of 14-day-old early isolation and weaning technology to control and purify infectious diseases. The ...
