Effect Of Coated Sodium Butyrate On Growth Performance And Blood Biochemical Indexes On Weaning Piglets

Coated sodium butyrate is inherent in outsourcing sodium butyrate product is a layer of fat, the formation of new products and services.Coated sodium butyrate on the application of livestock reported more, but coated sodium butyrate reports especially for coated the optimum dose of sodium butyrate reported in Dietary even fewer. The experiment by adding different levels in the diet coated sodium butyrate Weaning piglets weaned case measured growth performance, blood biochemical parameters and fecal microbiota.This test uses single-factor test, the 28-day-old 128 piglets were randomly divided into four treatments with four replicates of eight piglets.Select the genetic background similar average body weight of (6.37 ±0.11) kg of weaned piglets, A group as a test of the control group was fed the basal diet, the test group with different content packages to the basic diet is sodium butyrate, respectively 500g/t (group B), 1000g/t (group C),1500g/t (group D), the test cycle is 28d.Test is divided into 1～14d and 15～28d in two stages. The results showed that:1) In the three-stage trials 1～14d,15～28d and 1-28d, compared with the control group, Dietary 1000g/t,1500g/t coated sodium butyrate significantly increased average weaning ADG (P<0.05), significantly lower feed conversion ratio (P<0.05); 15-28d phase, significantly increased average daily feed intake (P<0.05);2) Compared with the control group, dietary 1000g/t,1500g/t coated sodium butyrate significantly increased weaning piglets serum TP, GLU, IgA, IgG; significantly reduce UN (P <0.05);3) Compared with the control group, dietary 1000g/t,1500g/t sodium butyrate package content to be weaned of various substances in the feces also changed significantly increased fecal apparent digestibility of CP, EE’s content (P<0.05);4) Compared with the control group, dietary 1000g/t,1500g/t coated sodium butyrate weaned, significantly reduced the number of E. coli in vivo (P<0.05), significantly increased the number of another species of lactobacilli (P<0.05);5) E. coli coated sodium butyrate between drug sensitivity between moderate sensitivity and high sensitivity.The test results above shows that supplementation with coated sodium butyrate feed can promote the growth of weaned pigs, weaned piglets immunity, weaned pigs nutrition apparent digestibility has also been improved, greatly reducing diarrhea piglets.Comprehensive analysis of the data indicators of this test, weaned piglets diet coated sodium butyrate optimal concentration 1000g/t.
