Abstract

The study aimed to determine the effect of “Biofeed-H-lysine” on production performance, blood lipid profiles and pathogenic bacteria in the intestines of ducks. A total of 240 male Bali ducklings (Anas sp.) were randomly divided into four experimental groups with 6 replicates and each replicate with 60 ducklings. Ducklings in Group 1 (n=60) served as healthy controls and were fed a basic diet without the addition of Biofeed-H-lysine. Ducklings in Groups 2, 3 and 4 were fed with addition of 1, 2 and 3% Biofeed-H-lysine per kg of feed. The results showed that the body weight gain, and feed efficiency in the group of ducklings that received biofeed-h-lysine were significantly different (P<0.05) higher than the control. Supplementation of 2-3% Biofeed-H-lysine in feed significantly (P<0.05) reduced blood serum cholesterol and triglyceride levels, and significantly (P<0.05) reduced the population of Coliform and E. coli bacteria in the intestines of ducks. It can be concluded that supplementation of 2-3% biofeed-H-lysine in feed can improve performance, as well as reduce serum cholesterol and pathogenic bacteria in the intestines of ducks.Keywords:Ducklings, Lysine, Pathogenic bacteria, Probiotics.
