چکیده
|
Study aims to determine effects of protein in formulated feed on specific growth,digestibility and survival of spiral babylon [babylonia spirata (linnaeus,1758)] snail. the snail average weights (10.19 ± 0.124) g per individu was stocked at a density of two snails per liter,and fed formulated feed twice daily (5 % of total biomass) with three different protein levels: 30 %,35 % and 40 % for 70 d. the results show that different protein contents significantly affected the growth of spiral babylon (p < 0.01) and protein digestibility,but not the survival of spiral babylon (p > 0.05) and spiral babylon needs 35 % protein in the formulated feed. © 2016 penerbit utm press. all rights reserved.
