Feed additive and preparation method thereof

Abstract

The invention provides a feed additive and a preparation method thereof. The additive is prepared from the following raw materials in parts by weight: 10 to 18 parts of cortex eucommiae, 12 to 20 parts of radix astragali seu hedysari, 10 to 20 parts of radix isatidis, 5 to 10 parts of radix paeoniae alba, 7 to 15 parts of poria cocos, 1 to 5 parts of vitamin E, 1 to 5 parts of trace elements, 2 to 8 parts of acidifier and 5 to 30 parts of galacto-oligosaccharide. The feed additive provided by the invention has the advantages that because Chinese herbal medicines, the vitamin E, the trace elements, the acidifier and the galacto-oligosaccharide are contained, the immunity of an animal body can be enhanced, the incidence of edema is reduced, and the utilization rate of the feed is improved; in addition, the reproduction of harmful microorganisms is controlled, and especially the galacto-oligosaccharide in the additive has the effect of promoting the multiplication of bifidobacterium, inhibiting the growth of harmful pathogens and spoilage bacteria, reducing the contents of harmful substances in colon and adjusting intestinal micro-ecology, thereby reducing a feed conversion ratio and a diarrhea rate and improving the growth performance of animals.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed additive and a preparation method thereof. Background technique [0002] For a long time, the use of synthetic feed additives such as antibiotics has greatly promoted the development of animal husbandry. Antibiotics play a very important role in ensuring animal health, promoting growth, saving feed and improving economic benefits. A large amount of antibiotics will cause many problems, such as pathogenic bacteria develop drug resistance, limit the animal's immune function, reduce the animal's immunity and disease resistance, inhibit the growth of beneficial bacteria in the intestinal tract of animals, destroy the intestinal microecological balance, Restricting the growth of animals, etc. In this regard, the European Union has strictly prohibited the addition of antibiotics in feed, and Japan and the United States have also made strict restrictions on the use of antibiotics in feed.

Problems solved by technology

[0003] In the modern breeding industry, especially the pig raising industry as an example, in order to give full play to the best production performance of sows, reduce the probability of disease infection and improve the growth performance of piglets, early isolation weaning technology is often used, and the digestive system of early weaned piglets is not yet fully developed. Difficulty with the nutritional stress of switching from liquid breast milk to grain-based solid feed

Therefore, weaned piglets are prone to comprehensive stress such as decreased feed intake, irritability, growth stagnation, diarrhea, edema, and decreased disease resistance, which will lead to an imbalance in the digestive tract flora, causing damage to the normal microbial flora of the digestive tract, and Escherichia coli , Salmonella and other disease strains multiply and cause bacterial enteritis. In severe cases, dead pigs may even result in death of piglets, causing significant economic losses to pig production.
