【BA Significant Effect】Broiler Growth Performance, Slaughter Rate, Lipid Metabolism

The effects of bile acids on the growth performance, slaughter performance, and lipid metabolism of broilers
Key Words: bile acids, broilers, growth performance, slaughter performance, lipid metabolism        

This experiment aims to investigate the effects of adding bile acids to the feed on the growth performance, slaughter performance, and lipid metabolism of broiler chickens. 240 birds,1-day-old Arbor Acres(AA) broiler chickens with consistent physical condition and similar body weight were selected and randomly divided into 2 groups, with 6 replicates in each group and 20 chickens in each replicate. 

The control group was fed with basic feed, while the experimental group added  300mg/kg bile acid to the basic feed. The experimental period is 42 days.

The Results Indicate that:        

• Compared with the control group, the feed conversion ratio of broilers aged 1-42 days in the experimental group was significantly reduced (P<0.05).
• Compared with the control group, the slaughter rate of broilers in the experimental group significantly increased (P<0.05), and there was a decreasing trend in abdominal fat percentage (P=0.071).
• Compared with the control group, the experimental group showed a decreasing trend in liver fat content (P=0.054), a significant decrease in serum alanine aminotransferase activity (P<0.05), and a decreasing trend in serum triglyceride content (P=0.090).

In summary, under the conditions of this experiment, adding 300mg/kg bile acid to the feed can reduce the feed conversion ratio of broiler chickens, increase the slaughter rate, and have a certain improvement effect on lipid metabolism.
