|
A three-month feeding trial was undertaken to evaluate the growth response of river terrapin (Batagur baska) hatchlings fed with tilapia feed, a combination of tilapia feed and kangkung (Ipomoea sp.), frog feed, a combination of frog feed and kangkung and only kangkung. The feeding ration was 2% of body weight per day. Terrapins fed with tilapia and frog feeds showed greater growth compared to the other treatments both in terms of mean weight gain per individual (133.40g 142.77g respectively) and mean increase in carapace length per individual (2.18cm and 2.30cm straight carapace length respectively) over the experimental period. The growth response of terrapins fed with (a) tilapia feed and a combination of tilapia feed and kangkung and (b) frog feed and a combination of frog feed and kangkung were also statistically different. No significant difference in weight gain and increase in carapace length were detected between terrapins fed with tilapia and frog feeds; as well as a combination of tilapia feed and kangkung, and a combination of frog feed and kangkung. Kangkung, on the other hand, produced significantly poor growth response in comparison to the other treatments. From the results of this study, it can be concluded that the tilapia and frog feeds produced the best growth response compared to the other combinations of feeds, probably because the commercially-available feeds contain a high percentage of protein (34% in tilapia feed and 38% in frog feed). However, further studies on the digestibility of the feeds should be carried out to gauge the level of digestibility of each of the nutrients found in the feeds.
