Composite acidifier for reducing post-weaning diarrhea rate

Abstract

The invention relates to a composite acidifier for reducing post-weaning diarrhea rate, and the composite acidifier comprises citric acid, formic acid, lactic acid and butyric acid at the mass ratio of 1:1:(0.5-0.8):0.5; and the citric acid, the formic acid, the lactic acid and the butyric acid are carried by being absorbed by silica gel. The composite acidifier can be used for increasing the daily feed intake and the daily gain of piglets, reducing the material weight ratio, saving the feeding cost and reducing the diarrhea rate of the piglets.

Description

technical field [0001] The invention belongs to the technical field of feed additives and relates to a compound acidifier for reducing the diarrhea rate of weaned piglets. Background technique [0002] In order to maximize the reproductive performance of sows, early weaning of piglets (3-4 weeks old) is a commonly used method in production. However, due to the immature development of the digestive system of early weaned piglets, the regulation mechanism of nerves and endocrine has not been fully established, so after weaning, the piglets are prone to slow growth, diarrhea rate and death during the transition from sucking breast milk to eating solid feed Increased rates of weaning stress syndrome. In particular, the high pH in the intestinal tract of weaned piglets will not only affect the activity of digestive enzymes in the small intestine, but also cause the proliferation of pathogenic bacteria, resulting in nutritional or pathogenic diarrhea in piglets. [0003] It has ...

AI Technical Summary

Problems solved by technology

[0004] In recent years, there have been many reports at home and abroad about adding acidifiers to the diet of weaned piglets to solve the problem of weaning stress syndrome in piglets, but most of the acidifier products involved in these reports have not been protected. , it is easy to quickly release H+ in the stomach of piglets, and it may also be buffered by some feed ingredients, but cannot reach the small intestine and large intestine of piglets to play an acidifying role, so the intestinal adaptation of piglets after weaning cannot be completed as soon as possible

[0005] Through searching, it is found that at present, there is no literature report at home and abroad that the acidifying agent is adsorbed and carried by silica gel to overcome the above defects.
