Commercial Carcas cuts of Bali duck (Anas Sp.) given water extract Asystasia gangetica subsp. Micrantha in drinking water

The productivity of bali ducks as meat producers needs to be increased in quantity and quality. This study aims to determine the effect of water extract of Asystasia gangetica (L) subsp. Micrantha in increasing the commercial cut of bali duck.100 bali ducks were used with four treatments and five replicates, and each replicate consisted of 5 bali ducks. Bali ducks in treatment A were the control and were not given water extract of Asystasia gangetica (L) subsp. Micrantha in drinking water, while treatments B, C, and D were given water extract of Asystasia gangetica (L) subsp. Micrantha 2%, 4%, and 6%  in drinking water. The results showed that the carcass weight of bali ducks was given 6% water extract of Asystasia gangetica (L) subsp. Micrantha (D) was significantly (P<0.05) higher by 7.85% compared to bali ducks in treatment A (control). The chest percentage of bali ducks was given 4% and 6% water extract of Asystasia gangetica (L) subsp. Micrantha (C and D) was 10.17% and 12.94%, significantly (P<0.05) higher than bali ducks in treatment A (control). The back percentage of bali ducks was given 4% and 6% water extract of Asystasia gangetica (L) subsp. Micrantha (C and D) was 8.64% and 9.6%, significantly (P<0.05) lower than bali ducks in treatment A (control). Based on the research results, it was concluded that the water extract of Asystasia gangetica (L) subsp. Micrantha in drinking water at a level of 4 - 6% increases the percentage of the chest and reduces the percentage of the back, and up to a level of 6% can increase the carcass weight of bali ducks.
