Abdominal fat distribution of bali ducks male fed with Asystasia gangetica (L) subsp. Micrantha leaf water extract

Bali ducks are one type of poultry that has the potential to be a supplier of animal needs besides chickens, but their productivity is still low. This study aims to see the effect of giving Asystasia gangetica leaf water extract on the distribution of abdominal fat in bali ducks male. The experimental design used a completely randomized design (CRD) with four treatments and five replications and each treatment unit was filled with 3 ducks, so that were used 60 bali ducks male. The treatment of Asystasia gangetica leaf water extract through drinking water was: 0% Asystasia gangetica leaf water extract (A); 2% Asystasia gangetica leaf water extract (B); 4% Asystasia gangetica leaf water extract (C); and 6% Asystasia gangetica leaf water extract (D). The variables observed were slaughter weight, percentage (pad fat, mesenteric fat, ventricular fat, and abdominal fat). The results of the study showed that the slaughter weight and percentage of ventricle fat of bali ducks male given 2-6% Asystasia gangetica leaf water extract had no different effect (P>0.05) compared to ducks given 0% Asystasia gangetica leaf water extract, but giving 6% Asystasia gangetica leaf water extract was able to reduce the percentage of abdominal fat by 11.013% compared to treatments A, B, and C. It can be concluded that giving Asystasia gangetica leaf water extract at levels 2 - 6% did not affect the slaughter weight and percentage of ventricle fat and was able to reduce the percentage of pad fat, mesentery, and abdomen, and at level 6% produced the best results.
