For realizing the foregoing invention purpose, the present invention adopts following technical proposals to be achieved:
A kind of feed addictive, said feed addictive comprises following component, the bacterium amount of saccharomyces boulardii is not less than 5 * 108/g; The bacterium amount of bacillus licheniformis is not less than 4 * 109/g; The bacterium amount of bacillus subtilis is not less than 8 * 109/g; The enzyme work of zytase is not less than 800U/g; Carrier is not less than 600 mg/g.
Further improvement to technical scheme: said saccharomyces boulardii bacterium amount is 5 * 108/g; Said bacillus licheniformis bacterium amount is 4 * 109/g; Said bacillus subtilis bacterium amount is 8 * 109/g; Said xylanase activity is 800U/g; Said carrier is 600 mg/g.
Further improvement to technical scheme: said carrier is a maize peel, and 30 order oversizes are 0.
The present invention also provides the application of said feed addictive in alleviating prevention of sow constipation.
Further improvement to technical scheme: the addition of said feed addictive is 1 ‰ of a perfect compound feed gross weight-3 ‰, directly it is added in the perfect compound feed and feeds.
Further improvement to technical scheme: said feed addictive is fed to the constipation sow with premix or concentrate feed form.
Further improvement to technical scheme: said sow is gestation or lactating sow.
Compared with prior art, advantage of the present invention and good effect are:
Feed addictive according to the invention is a compound micro-ecological preparation; Comprise multiple bioactive ingredients such as saccharomyces boulardii, bacillus licheniformis, bacillus subtilis and zytase; It is main body with the saccharomyces boulardii; Adjustment sow intestinal microecology flora through stimulating enteric plexus, is accelerated intestines peristalsis and is solved and prevent the prevention of sow constipation problem; Add the content that can improve the hindgut beneficial bacterium behind the additive of the present invention, the increasing of intestines wall expansive force has been promoted the wriggling of hindgut.Compare advantage such as have safety, efficient, selectivity and addition are few with existing additive; Use said feed addictive can alleviate prevention of sow constipation, improve sow health status.
Experimental studies results of the present invention shows that in daily ration or drinking-water, adding said feed addictive has obvious effects to reducing prevention of sow constipation, and method for using is simple and convenient; And, add the environment that said additive can also improve the child care house in the sow daily ration, reduce colibacillary content in the environment, the diarrhoea of sucking pig also there is certain improvement.
After the advantages specific embodiment of the present invention, other characteristics of the present invention and advantage will become clearer.
Description of drawings
Fig. 1 is the experimental result of feed addictive according to the invention to the prevention of sow constipation influence.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment technical scheme of the present invention is done further detailed explanation.
Embodiment 1
Feed addictive according to the invention is a composite type microecology preparation, and it comprises following component, and by mass percentage: the bacterium amount of saccharomyces boulardii is not less than 5 * 108/g; The bacterium amount of said bacillus licheniformis is not less than 4 * 109/g; The bacterium amount of said bacillus subtilis is not less than 8 * 109/g; The enzyme work of zytase is not less than 800U/g; Carrier is not less than 600 mg/g.
The concrete component of microbial forage additive described in the present embodiment is: saccharomyces boulardii is 5 * 108/g; Bacillus licheniformis is 4 * 109/g; Bacillus subtilis is 8 * 109/g; Zytase is 800U/g; Carrier is 600 mg/g.
The dominant mechanism that feed addictive according to the invention alleviates prevention of sow constipation is following: be main body with the saccharomyces boulardii, suppress the excessive breeding of harmful bacterium, increase the content of beneficial bacterium.Through adding feed addictive according to the invention, improved the digestibility of hindgut fiber, the increasing of intestines wall expansive force has been promoted the wriggling of hindgut.
Select 160 of 2 gestational age sows, be divided into 2 groups at random, promptly (add additive according to the invention by 500 gram/tons in the feed behind the insemination of sows, preceding 15 days of the expected date of childbirth began to add by 1000 g/ tons experimental group.) and the blank group, duration of trial is to play the same day till 28 days postpartum from breeding.Feed addictive according to the invention to prevention of sow constipation to influence experimental result as shown in Figure 1, a number of times=sow number * fate of feeding of feeding; An a constipation number of times=constipation sow number * constipation fate; A constipation rate=constipation number of times/number of times of feeding; Feed addictive according to the invention can significantly reduce the incidence of sow in the gestational period (reducing by 6.6%, P<0.01) and (reducing by 20.2%, P<0.01) constipation lactation period.
Above embodiment is only in order to explaining technical scheme of the present invention, but not limits it; Although the present invention has been carried out detailed explanation with reference to previous embodiment, for the person of ordinary skill of the art, still can make amendment to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of relevant art scheme break away from the spirit and the scope of the present invention's technical scheme required for protection.
