Effects of replacement of fish mill with golden snail mill in ration to performance of male Bali duck

Abstract

Research objective was to know performance of male Bali duck fed ration half or all replacement of fish mill with golden snail mill. The research results showed that initial body weight of the animals fed ration without replacement of fish mill (R0), replacement 25% fish mill with golden snail mill (R1), replacement 50% fish mill with golden snail mill (R2), replacement 75% fish mill with golden snail mill (R3) and replacement 100% fish mill with golden snail mill (R4) were 610.00 g, 604.25 g, 607.75 g, 591.50 g and 615.50 g respectively which was statistically no significant difference (P > 0.05). End body weight and body weight gain of the animals fed treatment ration R3 and R4 were lower significant difference (P <0.05) than on the animals fed R2, R1 and R0. There was no significant difference (P < 0.05) on variable of ration consumption and ration conversion of the animals fed ration fish mill replacement with golden snail mill on different level. From the research results could be concluded that fish mill in ration could be replaced with golden snail mill up to 50% without decreased of the animal performance.
