Abstract

This study was conducted to investigate the effect of feeds on two different breeds of snails. One hundred and eighty (Archachatinamarginata and Achatinafulica) snails were used for the experiment. Sixty snails were used per treatment with three replicates consisting of twenty snails each. They were intensively raised for ten weeks and fed with 100% compounded feed (T1), 50% roughages and 50% compounded feed (T2), and 100% roughages (T3) to evaluate their performance and digestibility, carcass and organ characteristics, proximate and mineral composition, physicochemical analysis, haemolyph parameters and organoleptic properties in a 2x3 factorial Completely Randomised Design. Results revealed thatthe A.marginata breed had higherfeed intake, weight gain, digestibility, and feed conversion ratio (FCR) than A. fulica. The snails fed with T2 had the highest feed intake, and weight gain however, no significant (P>0.05) difference was observed in digestibility and FCR of T1 and T2.High mortality rate was recorded in snails fed with T3 while the lowest mortality was recorded in the snails fed with T2. Snail muscles fed with T1 and T2 were significantly (P<0.05) high in protein content than T3 however, there was no significant (P>0.05) difference in mineral content of snail muscles fed T1, T2, and T3. A. marginata breed had the better protein, Ca, Fe and P compared to A.fulica breed. For physicochemical analysis, T2 had a higher (P<0.05) Water holding capacity (WHC) of (77.70 %) with the lowest cooking loss (73.94 %) while T3 has the
lowest WHC (50.58 %) with the highest cooking loss(83.83%). A. marginata breed hadthe highest WHC with the lowest cooking loss, thermal shortening, cold shortening, and thaw rigour,A. fulicahowever, recorded the highest cooking loss, coldand thermal shortening, thaw rigour but the lowest WHC. In haemolyph parameters evaluated, A. marginatawas
better in A. fulica (P<0.05) for all parameters except cholesterol. The panelists considered and accepted T1 and T2 while A. marginata breed was rated higher (P<0.05) than A.fulica in organoleptic properties.
