The Research And Develop Of The Rumen-protected Choline

This article optional ethylcellulose(EC),chitosan(CS),acrylic resin materialⅣused three air suspension prepared by a different compound wall material of the package was Rumen choline chloride,and use of simulation in vitro digestion Of law,Rumen nylon bags of freeze-dried powder and small intestine was determined by a different Rumen choline chloride products Rumen stability and digestibility small intestine,thus select the best package was wall material,the final adoption of a feeding trial on the rumen Choline chloride on the growth performance of goats. This research including four experiments.1.Test were selected silicon dioxide,cyclodextrin do granulation liquid choline chloride curing the carrier,CMC(CMC) do adhesives,microcrystalline cellulose(MCC) do excipients,the liquid chlorine Choline of the best cure granulation technology research.The results showed that:silicon dioxide absorption capacity than the cyclodextrin better,the best ratio is 1:1.2.Selection of Test selection ethylcellulose(EC),chitosan(CS),Ⅳthree acrylic resin materials,through the air suspended prepared by the rumen choline chloride,used in vitro method to simulate the digestive juice Rumen chloride Gall to release the effective rate for testing.The results showed that,comparison of costs and effects of No.2,products(from the wall to build combinations:5%Ⅳ, 3%CS and 5%EC) and 6 products(from the wall to build combinations:5%Ⅳ, 3%EC and 5%CS) in the rumen is better than other products.3.Rumen test through nylon bags of freeze-dried powder and small intestine Determination of the rumen choline chloride Rumen stability of the small intestine and digestibility,research on a different wall material Rumen choline chloride controlled release properties of the study.The results showed that:5%acrylic resinⅣ,3%chitosan(CS),5%ethylcellulose(EC) of the package was the best Rumen choline chloride.4.This test optional 8-month-old black goat health Macheng 12,was a one-block design,according to the principle of similar weight,divided into four groups,each with three repeat,repeat each one.The control group-based diet group, for the treatment groupⅠconcentrate supplementary materials +0.1%Rumen choline chloride group had to deal with groupⅡconcentrate +0.2%expected to add a group Rumen choline chloride,for the treatment groupⅢConcentrate supplementary material + 0.3%over the rumen choline chloride group.5-week trial period,the average of a goat on the intake(ADFI),average daily gain(ADG) and Liao Roubi(FCR) and the goat serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),total Protein(TP),albumin(ALB),MG(GLO),urea nitrogen(BUN),ALP(AKP),triglycerides(TG) and total cholesterol(TCH) the content.The results showed that:The results show that:in this test under the condition of 1.2 times the need to maintain,on the basis of goats concentrate added compound add 0.1%RPC,goats,the average daily gain increased 60.29 g(P＜0.05),feed conversion ratio decreased 7.21(P＜0.05);goat serum alanine aminotransferase(ALT) decreased 5.83(P＜0.05).Draw a comparison of Rumen-protected chlorine chloride products in the rumen goat concentrate the best content compound added 0.1 percent.
