Effects of the Replacing of Fish Meal with Freshwater Snail Flesh (Pomacea paludosa) Treated with Bromelain Enzyme on Growth Performance, Relatively Organ Weight, and Digestibility of Alabio Ducks (Anas plathyrhyncos Borneo

This study aimed to determine the effects of the replacing of fish meal with freshwater snail flesh (Pomacea paludosa) treated with bromelin enzyme (FSFIBE) on growth performance, relatively organ weight, and digestibility of Alabio ducks (Anas plathyrhyncos borneo). A total of 210 one-day old ducks male Alabio with an average body weight of 45.26±2.59 g were placed in colony-shaped pen, and each pen contained seven ducks. The trial design used was completely randomized design with five treatments and six replications for each one, consisting of seven ducks. The treatment diet was formulated as follows: T0 basal diet + 100% fish meal (10% in diet) (10:0), T1: basal diet + 75% fish meal (7.5% in diet)+ 25% FSFIBE(2.5% in diet) (7.5:2.5), T2: basal diet + 50% fish meal (5% in diet)+ 50% FSFIBE( 5% in diet) (5:5), T3: basal diet + 25 % fish meal (2.5% in diet)+ 75% freshwater snail flesh incubated bromelain enzyme (7.5% in diet) (2.5:7.5), T4: basal diet + 0 % fish meal (0% in diet)+ 100% FSFIBE(10% in diet) (0:10). The parameters observed was growth performance and digestibility. Result were analyses using general linear model and if a significant effect was identified, least significant differences (LSD) then applied. The result showed using freshwater snail for fish meal give significant difference (p < 0.05) on the apparent metabolizable energy-n corrected (AMEn) and reduce feed conversion ratio (FCR). It can be concluded using fresh water snail can be used as replacement for fish meal on Alabio ducks without any adverse effects.
