Feed additive for preventing diarrhea of ​​weaned piglets and promoting growth and preparation method thereof

Abstract

The invention discloses a feed additive for preventing diarrhea and promoting growth of a weaned piglet and a preparation method of the feed additive. The feed additive comprises a traditional Chinese medicine composition and porous zinc oxide, wherein the traditional Chinese medicine composition comprises the following raw materials in parts by weight: 6-12 parts of codonopsis pilosula, 6-12 parts of poria cocos, 6-15 parts of atractylodes macrocephala, 5-10 parts of liquorice, 10-15 parts of dark plums, 7-14 parts of curcuma zedoary, 10-15 parts of medicated leaven, 4-10 parts of katsumadai seeds, 6-12 parts of alisma plantago-aquatica linn, 4-8 parts of immature bitter oranges, 3-9 parts of malt, 5-15 parts of tangerine peels and 4-10 parts of pulsatilla roots, wherein the weight ratio of porous zinc oxide to Chinese herbal medicines is (1 : 10) to (3 : 10). According to the feed additive, the specific traditional Chinese medicine composition is adopted, and the diarrhea of the weaned piglet can be effectively prevented through a plurality of modes of generating interferon, inhibiting growth of harmful bacteria and the like; porous zinc oxide has a very large specific surface area, can provide a large quantity of acting sites of zinc oxide molecules, and can achieve a diarrhea-resistant effect of general zinc oxide with relatively small dosage; diarrhea resistance of traditional Chinese medicines is organically combined with porous zinc oxide, so that very good diarrhea-resistant and growth-promoting effects can be achieved.

Description

technical field [0001] The invention belongs to the field of animal feed, and relates to a feed additive for preventing diarrhea and promoting growth of weaned piglets. Background technique [0002] Early weaning is increasingly practiced in the modern pig industry to maximize production efficiency. However, affected by psychological, environmental and nutritional stress, early weaned piglets often suffer from "early weaned piglet syndrome", manifested as poor appetite, digestive disorders, diarrhea, growth retardation, and low feed utilization. In particular, the problem of diarrhea due to immunodeficiency and various stresses caused by weaning is particularly prominent. Post-weaning diarrhea significantly reduces the growth rate of weaned piglets, increases morbidity and mortality, and increases treatment costs. What is more serious is that the growth inhibition caused by post-weaning diarrhea will significantly reduce the later production performance and cause huge losse...

AI Technical Summary

Problems solved by technology

However, with the emergence of drug resistance problems caused by the use of drugs in feed, more and more countries have gradually reduced or banned the use of antibiotics; at the same time, long-term use of high-dose zinc oxide will cause thick and long hair and dull skin and other phenomena and affect growth and development, and cause a waste of zinc sources. The absorption rate of high-dose zinc oxide is very low, and most of the zinc is excreted into the environment with feces, causing environmental pollution.
