Effect of protein and lipid feedstuff on palatability of Babylonia areolata (Thai)

Abstract

This study aimed to evaluate the palatability of protein and lipid feedstuff in juvenile spotted Babylon (Babylonia areolata) by measuring the speed of animal movement to food source. The protein feedstuff used in the experiment included shrimp head meal, soybean meal, squid meal, fish meal and fish protein extract and the lipid feedstuff included fish oil, squid oil, soybean oil and mixed oil. The results show that group fed fish protein extract moved 23.07±8.09 cm/min which was the fastest and this group differed significantly from the groups fed shrimp head meal and soybean meal (P<0.05). In the other experiment with lipid feedstuff, the group tested with mixed oil showed the highest speed at 22.57±6.81 cm/min and this was significantly different (P<0.05) compared to the groups fed squid oil and soybean oil. It was concluded that the fish protein extract and mixed oil could be introduced as feedstuff of Babylonia areolata for appetite stimulation.
