Embodiment 1

[0017] (1) The content of anti-nutritional factors in the basic diet of piglets: the anti-nutritional factors in the basic diet of corn and soybean meal for piglets are non-starch polysaccharides (NSP) such as xylan, dextran, mannan, cellulose and pectin substance. Wherein the content of anti-nutritional factors is as shown in Table 1, xylan is 4.75%, which contains 0.99% soluble xylan and 3.76% insoluble xylan; dextran content accounts for 1.51%; mannan content It is 0.49%; the cellulose content is 2.92%.

[0034] (1) In-situ screening: According to the dynamic evolution characteristics of animal development and digestive tract microecology, combined with its feed design principles, new probiotics such as Bacillus subtilis, Bacillus licheniformis and Clostridium butyricum were screened from the intestinal tract of healthy animals These strains have strong acid resistance and bile salt resistance, good in vitro inhibitory ability against pathogenic Escherichia coli, and strong adaptability, and are easily accepted by other flora in the intestinal tract of suckling piglets. Good colonization ability.

[0047] (1) Comparison of animal experiments: 120 21-day-old weaned Duroc × Landrace × Large White weaned piglets were selected, with an average body weight of about 7 kg. According to the principle of similar body weight, they were randomly divided into 4 treatments. Each treatment has 3 breeding pens, and each breeding pen has 10 piglets. The pre-feeding was about 3 days, and the test period was 21 days. The basal diet was formulated with reference to the nutritional requirements of NRC (2012) pigs, and 0.1% and 0.5% functional oligosaccharides (xylooligosaccharides, mannose oligosaccharides, and galactooligosaccharides) were added to treatment groups 3 and 4, respectively. aldehyde acid). The breeding test room was well ventilated, the room temperature was maintained at 22-25°C, and the experiment was free to eat and drink water.

Abstract

The invention relates to the field of a feed additive, and particularly relates to a compound feed additive replacing feed antibiotics in a piglet daily diet, and applications of the compound feed additive. The compound feed additive comprises a compound enzyme preparation applicable to piglets, a microecological preparation and a functional oligosaccharide. The compound additive comprises an NSP enzyme capable of degrading antinutritional factors in the feed, so that the growth performance of piglets and the utilization rate of the feed can be effectively improved, the feed-weight ratio can be reduced by 12.88%, the average daily grain can be improved by 25.6%, and the effect is far higher than that of the feed antibiotics; the probiotic flora including bacillus subtilis, bacillus licheniformis, clostridium butyricum and the like are increased, small amount of functional oligosaccharide is added, so that the microecological environment of animal intestinal tracts can be improved, the growth and propagation of pathogenic microorganisms can be inhibited, the stress reaction of weaned piglets can be solved, the diarrhea rate and morbidity of the sucking piglets can be greatly reduced, the action effect is superior to those of the feed antibiotics, and the feed additive can effectively replace feed antibiotics in a piglet daily diet.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a compound feed additive which can replace feed antibiotics in piglet rations and an application thereof. Background technique [0002] Since the 1940s, antibiotics have been widely used as feed additives in livestock and poultry farming. It can reduce the diarrhea rate of animals under certain energy conditions, regulate intestinal microbial flora, and inhibit pathogenic bacteria and hosts from competing for nutrients. Thereby improving animal growth performance and feed utilization. [0003] With the extensive use of antibiotics in feed, people's health is seriously threatened. According to statistics, among the feed antibiotics used in the world at present, 42% are used for growth promotion, and only 18% are used for treatment. Abuse of antibiotics is widespread. The long-term use of antibiotics will cause the problem of drug resistance of pathogenic bacteria, causing many str...
