不同组合益生菌对0～8周龄犊牛生长性能及血清生化指标的影响
Effects of Different Combinations of Probiotics on Growth Performance and Serum Biochemical Parameters in Dairy Calves Aged from 0 to 8 Weeks
摘要
Abstract
This study examined the effects of different combinations of probiotics on growth performance and serum biochemical parameters in preruminant Chinese Holstein calves. Twenty-four newborn Holstein calves were randomly divided into 4 groups with 3 males and 3 females in each group. Calves were offered a basal diet including milk replacer, starter diet and Chinese wildrye (control diet, group A) , a basal diet supplemented with Bacillus licheniformis (group B) , a basal diet supplemented with Bacillus licheniformis and Bacillus subti-lis (group C) , and a basal diet supplemented with Bacillus licheniformis, Bacillus subtilis and Lactobacillus plantarum (group D) , respectively. The ratio of each microbial strain for group C and group D was 1:1 and 1:1:1 in the bacterial counts, respectively. Each calf was offered 2 ?1010 CFU of probiotics per day. The total trial period was 8 weeks, and divided into 0-2, 2-4, 4-6 and 6-8 weeks for each period. Body weight and body measurement were recorded and blood samples were collected fortnightly, feed intake and fecal score were recorded every day. The results showed that in the trial of 0-8 weeks, average daily gain of calves in the group B was significantly higher than that in the group A (P < 0. 05) , but F/G had no differences among four groups (P > 0. 05 ). At the end of the trial, body structure index in groups B and D was higher than that in the group A (P <0. 05). The probiotics did not affect dry matter intake, fecal score and serum biochemical parameters of calves in four groups (P >0. 05). It is concluded that adding Bacillus licheniformis into the diet for calves can increase average daily gain of calves in the trial of 0-8 weeks and body structure index at the end of the trial, and adding Bacillus licheniformis, Bacillus subtilis and Lactobacillus plantarum into the diet for calves can increase body structure index at the end of the trial. However, adding probiotics into the diet for calves has no effect on serum biochemical parameters of animals.关键词
