The Effect of Replacing Antibiotics Feed Additive with Gluconic Acid, Glut amine and their Combination on Production Performance of the Piglets
摘要
Abstract
[ Objective ] The purpose of this article was to study the effect of replacing antibiotics feed additive with gluconic acid, glutamine and their combination on production performance of the piglets in intensive production conditions. [ Method ] 24 litters of 1 - day - old piglets were selected and randomly divided into four groups with 6 replicates per group,and the experiment lasted for 42 days. The control groupwas fed basal diet added antibiotic (60 mg/kg colistin, 75 mg/kg chlortetracycline) ; The GA group was fed the basal diet added 1. 5 g GA; The GN group was fed the basal diet added 2. 0 g GN; The GA + GN group was fed the basal diet with 1. 5 g GA +2.0 gGN. Piglets were weaned at 28 d of age. The litter was used as ■ replicate. Piglets were individually weighted at 1 d, 21 d, 28 d and 42 d of age, respectively. The weight of feed offered and feed remaining were recorded daily, while the amount of piglets, diarrhea and mortality were recorded in each litter. The average daily feed intake, average daily gain, feed intake to body weight gain, diarrhea ratio and death ratio were calculated at every stage and the whole trial period. [Result]From 21 d to 41 d, compared with the control group, the piglets of GA group, GN group, GA + GN group were decreased 8.00% (P >0.05), 16.00% (P < 0. 05), 8. 00% (P > 0. 05) , respectively; Diarrhea head times in each group were 37 , 31, 27 , 18 at the whole trial period, showing a gradually decreasing trend; About the average daily feed intake, the average body weight, the feed conversion ratio and the death ratio, the piglets in trial group and those in control group had no significant difference (P >0.05) . Among the piglets in trial groups, there was no significant difference (P>0. 05). [ Conclusion] Collectively, the piglets in the antibiotics -treated group had a better average daily gain than those in each replacing group from 21 d to 42 d, but compared with each replacing group, the average daily feed intake, live weight, feed intake to body weight gain ratio and other index of the antibiotics - treated group piglets were not significantly different. Compared with piglets of antibiotics - treated group, diarrhea frequency in each replacing group had a decreasing trend. This study provides a reference basis for replacing antibiotics feed additive of the piglet diet with gluconic acid, glutamine or gluconic acid + glutamine in intensive production system.关键词
