Feed for early weaned suckling pigs

Abstract

The invention relates to a feed for early weaned piglets, which belongs to the field of the feed. Main ingredients of the feed comprise expanded corn, full-fat soybean, fat powder, steam fish meal, acidified whey powder, fermented soybean meal, a complex enzyme preparation, a micro-ecological preparation, amino acids, complex vitamins, complex trace elements and the like. The digestive physiological characteristics of the weaned piglets are fully considered on the selection and the processing of raw materials, thereby greatly improving the palatability and the digestion rate of the feed; simultaneously, through the synergistic compatibility of an egg yolk antibody, lactein, sodium humate and the complex micro-ecological preparation, the diarrhea rate of the weaned piglets is reduced, the effects are superior to those of adding antibiotics into the feed, and the feed is the green, environmentally-friendly and nuisanceless feed. An animal feeding experiment proves that the feeding effects are ideal, the palatability is good, the piglets after weaning are high in average feed intake, fast in daily weight gain and low in diarrhea rate, and the feed has a good promoting effect for growth and health conditions of the weaned piglets and can meet the demands of most of raisers at present.

Description

Technical field [0001] The invention relates to an early weaned suckling pig feed, belonging to the field of feed. Background technique [0002] Weaned suckling pigs have the characteristics of fast growth and development, lack of innate immunity, immature digestive function, etc., coupled with weaning stress, resulting in low feed intake, reduced digestibility, slow growth or even negative growth, prone to diarrhea, and high mortality . Among them, the hazard caused by diarrhea ranks first. According to the survey, the deaths of piglets caused by diarrhea in China accounted for 39.8% of the total number of piglet deaths. Among them, enterotoxingenic E.coli (ETEC) is the cause of piglet diarrhea in large-scale pig farms. The most important pathogenic Escherichia coli, so the healthy breeding of weaning piglets has always been a difficult problem in the pig industry. Whether the weaning pigs can survive the weaning period and grow well, it is important for survival, later growth ...

AI Technical Summary

Problems solved by technology

[0003] At present, the main problems in feed for early weaned suckling pigs are: first, the feed digestibility is not high, and the feeding amount needs to be controlled artificially in the first three days after weaning, and the suckling pigs cannot eat freely, otherwise diarrhea will be caused by indigestion of feed; The low feed intake of suckling pigs after weaning leads to slow growth. The third is that weaned piglets are prone to diarrhea, and the diarrhea rate is relatively high

In order to solve the above problems, most enterprises use feed materials with good palatability, easy digestion and absorption, and low anti-nutritional factors, and at the same time add some additives such as enzyme preparations, acidifiers and food attractants to improve the palatability and digestibility of feed. Improve the feed intake and growth rate of suckling pigs, but in practical applications, due to various reasons such as formula design, raw material selection, pretreatment, quality control, etc., the actual effect is not ideal

In order to control post-weaning diarrhea of ​​piglets, high-dose zinc oxide (ZnO) and large-dose or over-dose antibiotics are used. Although the above substances have certain effects on controlling diarrhea, the abuse of antibiotics will not only promote the increase of drug-resistant strains. Residues in animals can also endanger human health; antibiotics excreted by animals can also destroy the normal microbial flora in the soil, resulting in imbalance of micro-ecological balance

Most of the high-dose zinc oxide is excreted from the body, causing environmental pollution, and at the same time endangering the intestinal health of piglets and affecting the later growth rate
