Abstract

Abstract:

The purpose of this experiment is to investigate the effects of drinking water type basil oil-citric acid composite formulation on the production performance and gut microbiota of broiler chickens. 150 3-week-old Chuzhou Sanhuang broiler chickens were selected and randomly divided into 2 groups, with 3 replicates in each group and 25 chickens in each replicate. The control group drank clean water. The drinking water of the experimental group was supplemented with 0.1% basil oil-citric acid composite formulation throughout the first and fifth weeks, and did not add during the remaining time periods. Both groups were fed with mid stage complete compound feed for broiler chickens. The experimental period is a total of 7 weeks. The results showed that adding 0.1% basil oil-citric acid composite formulation to drinking water could significantly increase the average body weight and daily weight gain of broilers, increase the number of Lactobacillus in feces at week 3, and reduce the number of Escherichia coli. However, there was no effect on the number of cecal microbiota at week 7. It indicates that adding 0.1% basil oil-citric acid composite formulation to drinking water can significantly improve the production performance of broilers.
