This research was conducted to study the effect of the level freshwater snail flesh soaked in biochar in feed on performance and digestive tract of male Alabio ducks. The ducklings used in this study were 200 day old ducks with an average initial body weight of 44.89 ± 2.71 g/head, which were put in to experimental cages with ten day old duck each. This study used a completely randomized design consisting of five treatments, four replications, and 10 ducklings in each plot. The treatment consist of: T0) basal feed + 0% freshwater snail flesh soaked with biochar; T1) basal feed + 2.5% freshwater snail flesh soaked with biochar; T2) basal feed + 5.0% freshwater snail flesh soaked with biochar; T3) basal feed + 7.5% freshwater snail flesh soaked with biochar and T4) basal feed + 10% freshwater snail flesh. The results have shown that there were significantly affected on feed intake, body weight gain, carcass weight, and percentage carcass yield by level treatment on male Alabio duck (P<0.01). Male Alabio duck fed diets containing freshwater snail flesh in feed showed that the male Alabio digestive tract profile had normal size. There was concluded that level of use of freshwater snail flesh soaked in biochar up to 5.0 % was able to improved feed intake, body weight gain, feed conversion, carcass weight, percentage carcass yield and the digestive track of male Alabio ducks. پرونده مقاله
