Problems solved by technology

Diarrhea caused by microecological feed additives such as insufficient digestive enzymes and bacterial flora has a good curative effect, but because the direction of improvement of various bacteria in the probiotics is not consistent, a single probiotics cannot effectively prevent and treat multiple diarrhea. piglet diarrhea

Embodiment 1

[0018] The feed additive of the present invention is a composite probiotic preparation, which includes the following components, in terms of mass percentage: the content of Bacillus licheniformis is not less than 2×10 9 pc / g; the content of Bacillus subtilis is not less than 4×10 9 each / g; the content of butyric acid bacteria is not higher than 5×10 7 per gram; the content of small peptides is not less than 300 mg / g, and the carrier is not less than 500 mg / g.

[0019] The specific components of the micro-ecological feed additive described in the present embodiment are: the amount of Bacillus licheniformis bacteria is 2×10 9 Individual / g; the amount of Bacillus subtilis is 4×10 9 individual / g; the amount of butyric acid bacteria is 5×10 7 each / g; small peptide content is 300mg / g; carrier content is 500mg / g. The carrier is corn bran, and the 30-mesh sieve is 0.

Embodiment 2

[0024] Embodiment 2, the repair experiment of feed additive to suckling piglet intestinal villi

[0025] Each litter of suckling piglets with diarrhea was randomly divided into 2 groups. Group I was injected with 0.5 ml of colistin sulfate injection every day, and group II was given 2 ml of compound probiotics once a day. Experimental results such as figure 1 with figure 2 As shown, it can be seen from the electronic scanning images that the intestinal mucosal repair of piglets treated with different methods is very different. The intestinal mucosa treated with compound probiotics is smoother than that of the antibiotic treatment group. Therefore, the repair of intestinal mucosa after the treatment with compound probiotics was significantly better than that of the antibiotic treatment group.

Abstract

The invention provides a feed additive and an application of the feed additive for alleviating diarrhea of piglet. The feed additive comprises the following components: no less than 2*10<9> / g of bacillus licheniformis, no less than 4*10<9> / g of bacillus subtilis, no more than 5*10<7> / g of butyric acid bacteria, small peptide with the content of being no less than 300mg / g and no less than 500mg / g of carrier. The feed additive provided by the invention can inhibit growth and breeding of harmful bacteria such as enteropathogenic escherichia coil, salmonella and the like and can effectively reduce occurring rate of yellow and white sour and other intestinal tract bacterial diarrhea of piglet; and butyric acid, metabolite of butyric acid bacteria, can promote regeneration and repairing of intestinal tract epithelial cells and improve absorbing capacity of intestinal tract. The feed additive provided by the invention has the advantages of safety, high efficiency, specificity, no residue, no side effect and the like.

Description

technical field [0001] The invention belongs to the technical field of livestock feed and relates to a feed additive, in particular to a micro-ecological feed additive and its application in alleviating piglet diarrhea. Background technique [0002] Piglet breeding is the basic stage of pig production and the most critical stage in the process of pig management. Due to the immature physiological development of piglets, the ability to resist the adverse external environment is relatively poor, which brings great difficulties to feeding management and disease prevention and control. From the birth of suckling piglets, exogenous bacteria begin to invade the intestinal tract of the animal, and gradually form a relatively stable flora environment. Three hours after birth, aerobic bacteria and facultative anaerobic bacteria became the dominant flora (reaching 80% of the total bacterial count). After that, anaerobic bacteria gradually replaced aerobic bacteria, and the types grad...
