Effect giving leaf extract of Asystasia gangetica (L) subsp. Micrantha on the performance of bali duck male

Bali duck has the potential to be a provider of meat to meet food needs, but is still constrained by the low growth rate of bali ducks as meat producers in terms of quality and quantity. This study aims to determine the effect of giving leaf extract of Asystasia gangetica (L) subsp. Micrantha on the performance of bali ducks male. The experimental design used a completely randomized design (CRD) with four treatments and five replications and each treatment unit was with 3 ducks, so that were used 60 bali duck male. Treatment leaf extract of Asystasia gangetica (L) subsp. Micrantha through drinking water: 0% Asystasia gangetica leaf extract (A); 2% Asystasia gangetica leaf extract (B); 4% Asystasia gangetica leaf extract (C); and 6% Asystasia gangetica leaf extract (D). The variables observed were initial body weight, feed consumption, drinking water consumption, final body weight, weight gain, and FCR. The results showed that feed consumption, final body weight, weight gain, and FCR of bali ducks male giving leaf extract Asystasia gangetica was not able to improve duck performance, but giving 4-6% could reduce duck drinking water consumption. It can be concluded that the administration leaf extract of Asystasia gangetica (L) subsp. Micrantha through drinking water has not been able to improve duck performance, administration of 4-6% can reduce drinking water consumption of bali duck male.
