Freshwater snail flesh (Pomacea paludosa) incubated with bromelain enzyme levels in feed on the carcass quality of Alabio male ducks (Anas plathyrhyncos Borneo)

Abstract

This study aimed to determine Freshwater snail flesh (Pomacea paludosa) incubated with bromelain enzyme levels in feed on the carcass quality of alabio male ducks. The treatment as ; P0 basal diet + 100% fish meal, P1 basal diet + 75% fish meal + 25% freswater snail flesh incubated bromelain enzym, P2 basal diet + 50% fish meal + 50% freswater snail flesh incubated bromelain enzym, P3 : basal diet + 25 % fish meal + 75% freswater snail flesh incubated bromelain enzym, P4 : basal diet + 100% freswater snail flesh . In each treatment, two male Alabio ducks were taken randomly and then slaughtered. The crude protein, crude fat, moisture, pH, and texture, by taking as many samples as 20 g of sample then mashed for 2 minutes and added 40 ml aquadest. pH measurement is done with pH meter, which was previously calibrated with buffer solution of pH 7.0 and 4.0. Meat tenderness is measured by using the shear warner bratzler tool Instron, , protein,fat and moiture using proximate analysis The result showed that level freshwater snail flesh incubated with bromelain enzym in feed up to 7.5-10% on Alabio male duck diets improved crude protein meat (21.51±0.19 to 23.90±0.40) but decreased meat moisture ( 69.46±0.79 to 62.79±0.27) and decreased crude fat meat (9.55±0.44 to 4.18±0.53). Meanwhile, the tenderness of the meat increased from 3.55% on the control feed to 26.77% on the feed using 7.5-10%.
