Effects of Acidifier and Oregano Oil Instead of Colistin Sulfate on Growth Performance, Diarrhea Rate and Caecal Microorganism Number of Weaned Piglets
摘要
Abstract
This experiment was conducted to study the effects of acidifier and oregano oil instead of colistin sulfate on growth performance, diarrhea rate and caecal microorganism number of weaned piglets. The single factor design was used in the experiment, one hundred and twenty 26-day-old piglets with similar parity and body weight were randomly divided into three groups with five replicates in each group and eight piglets in each replicate. Diets in each group were contained 75 mg/kg chlortetracycline and 10 mg/kg enramycin. In addi-tion, pigs in three groups were fed 0.10% acidifier+0.10% colistin sulfate,0.15% acidifier and 0.15% acidifi-er+0.03% oregano oil experimental diets, respectively. The experiment lasted for 14 days. The results showed as follows:1)there were no significant differences on average daily gain, ratio of feed to gain and diarrhea rate of weaned piglets among all groups(P>0.05). Compared with 0.10% acidifier+0.10% colistin sulfate group and 0.15% acidifier+0.03% oregano oil group, the average daily feed intake of 0.15% acidifier group had a trend to increase(P=0.066). 2)The caecal Salmonella number of 0.10% acidifier+0.10% colistin sul-fate group was significantly lower than that of 0.15% acidifier group(P<0.05),the numbers of Bifidobacteria and Lactobacillus in cecum of 0.15% acidifier+0.03% oregano oil group were significantly higher than those of 0.15% acidulant group(P<0.05), but there were no significant differences between the 0.15% acidifier+0.03% oregano oil group and 0.10% acidifier+0.10% colistin sulfate group(P>0.05). Accordingly, on the basis of the diets added 75 mg/kg chlortetracycline and 10 mg/kg enramycin,the effects of 0.15% acidifier or 0.15% acidifier+0.03% oregano oil on the growth performance of weaned piglets are similar to 0.10% colistin sulfate,0.15% acidulant+0.03% oregano oil also can increase the number of beneficial bacteria in cecum which is similar to 0.10% colistin sulfate. So the diets added acidifier and oregano oil can replace the colistin sulfate use in weaned piglets' diets.关键词
