德氏乳杆菌和低聚木糖对环江香猪生长性能和血浆生化参数的影响
Effects of Lactobacillus delbrueckii and Xylo?Oligosaccharides on Growth Performance and Plasma Biochemical Parameters of Huanjiang Mini?Pigs
摘要
Abstract
This experiment was conducted to study the effects of Lactobacillus delbrueckii and xylo?oligosac?charides on growth performance and plasma biochemical parameters of Huanjiang mini?pigs. A total of 96 Hua?njiang mini?pigs with an average body weight about 9.5 kg were randomly divided into 3 groups with 8 repli?cates per group and 4 pigs ( male∶female＝1∶1) per replicate. Pigs in control group were fed a basal diet, and those in trial groups 1 and 2 were fed experimental diets which supplemented with 0.05% Lactobacillus del?brueckii and 0.05% Lactobacillus delbrueckii+0.02% xylo?oligosaccharides, respectively, in the basal diet. The pre?test period was 3 days, and the trial period was 84 days. During the experiment, the feed intake was recorded daily, and the fasting body weights were weighed on days 1, 28, 56 and 84 of the trial, respectively. The average daily feed intake ( ADFI) , average daily gain ( ADG) and feed／gain ( F／G) were calculated on each stage. On days 28, 56 and 84 of the trial, blood samples were collected for determining plasma biochemi?cal parameters. The results showed that, compared with the control group, the ADG of trial groups 1 and 2 was significantly increased on day 29 to 56 of the trial ( P＜0.05) , the F／G of trial group 1 was significantly de?creased on day 57 to 84 of the trial ( P＜0.05) , and the F／G of trial groups 1 and 2 was significantly decreased on day 1 to 84 of the trial ( P＜0.05). Compared with the control group, on day 28 of the trial, the plasma tri?glyceride ( TG) and total protein ( TP) concentrations of trial group 1 were significantly increased ( P＜0.05) , as well as the plasma TP, albumin ( ALB) and TG concentrations and alkaline phosphatase ( ALP) activity of trial group 2; on day 56 of the trial, the plasma ammonia ( NH3) concentration and amylase ( AMS) activity of trial group 1 and plasma AMS activity of trial group 2 were significantly increased ( P＜0.05) ; on day 84 of the trial, the plasma glucose ( GLU) and TG concentrations and AMS and lactic dehydrogenase ( LDH) activi?ties of trial group 1 were significantly decreased ( P＜0.05) , and the plasma TP concentration of trial group 2 was significantly increased ( P＜0.05) , as well as the plasma aspartate aminotransferase ( AST) and LDH ac?tivities were significantly decreased ( P＜0.05). In addition, on day 56 of the trial, the plasma TP, ALB, urea nitrogen ( UN) , GLU, TG, cholesterol ( CHO) and low density lipoprotein cholesterol ( LDL?C) concentra?tions and hepatic lipase ( HL) activity of trial group 2 were significantly higher ( P＜0.05) , while AST concen?tration and LDH activity were significantly lower than those of control group and trial group 1 ( P＜0.05 ). These findings suggest that supplementation of Lactobacillus delbrueckii alone or combined with xylo?oligosac?charides in the diet can increase ADG and reduce F／G of Huanjiang mini?pigs, which may be related to bio?chemical parameters related to nitrogen and glycolipid metabolism.[ Chinese Journal of Animal Nutrition, 2019, 31(8) :3891?3897]关键词
