The relative weight of internal organs and digestive tract in native chickens age 12 weeks that are given various levels of BSF larvae meal (Hermetia illucens L) in the ration

The feed consumed is one factor that influences the development and anatomy of the internal organs and the digestive tract. This study was conducted to determine the effect of BSF larvae meal on the ratio of internal organ weight in native chickens. According to a completely randomized design, one hundred and forty one-day-old chicken (DOC) were randomly assigned to one of five treatments with four replications for each treatment. The treatment were: P0 = basal ration + 15% fish meal + 0% BSF larvae meal, P1 = basal ration + 11.25% fish meal + 3.75% BSF larvae meal , P2 = basal ration + fish meal 7.5 % + 7.5% BSF larvae meal , P3 = basal ration + 3.75% fish meal + 11.25% BSF larvae meal , P4 = basal ration + 0% fish meal + 15% BSF larvae meal . The results showed that P3 (3.75% fish meal + 11.25% BSF larvae) had a significant effect (P<0.05) on the percentage of heart weight and the percentage of the small intestine weight. Also, the treatment tends to increase the percentage of caecum weight. However, the treatment did not affect the liver, gizzard, pancreas, spleen, and colon weight. In conclusion, the use of BSF larvae meal does not negatively affect the internal organs and digestive tract of native chickens.
