Abstract
This study was aimed to evaluate the use ofPomacea canaliculatameal at various levels on the carcass physical composition, meat chemical composition, and haematological profile of Muscovy duck. There were four treatments included P0 (control feed), P1 (control feed + 10%Pomacea canaliculatameal), P2 (control feed+20%Pomacea canaliculatameal), P3 (control feed + 30%Pomacea canaliculatameal). The variables observed included final body weight, carcass weight, carcass yield, non-carcass weight, meat chemicals composition and haematological profile. The experimental design used a completely randomized design with analysis of variance and further orthogonal polynomial trials. The research results revealed that using golden snail meal in Muscovy duck feed had a significant effect (P<0.05) on the final body weight, carcass weight, carcass yield, commercial cuts composition, physical composition of the carcass, non-carcass composition, and heterophil. Descriptively, the meat chemicals composition of Muscovy duck withPomacea canaliculatameal was better than the control. The use of 30% golden snail meal in the male Muscovy duck diet provides the best performance on final body weight, slaughter weight, carcass yield, and drumstick weight parameters without negatively impacting haematology profile. The use golden snail meal provides the lowest carcass fat.
Highlights
Muscovy duck is a type of waterfowl with a high growth rate and carcass productivity
The highest final weight parameter was found in the use of 30% snail flour in the diet, which was 2847.33 grams/head (P
This study showed that use of snail meal until 30% in the diet did not harm productivity performance
Summary
Muscovy duck is a type of waterfowl with a high growth rate and carcass productivity. The Statistic Indonesia showed that Muscovy duck is included in the twelve largest types of livestock in the Bali Province [37]. The main feed proteins sources are soybean meal and meat bone meal. Based on data from the Ministry of Trade in 2020 regarding the import value for the food industry dregs, including soybean meal and meat bone meal, it was 2,910.8 million US$. The soybean meal portion in poultry ration ranges from 10-20% Based on these issues, it is necessary to explore alternative feed protein sources of cheap and quality to replace soybean or meat bone meal
