Comparative reproductive performance of Giant African Land Snail (Archachatina marginata) fed Leucaena leucocephala

The study was carried out at the sub-station of the Faculty of Agriculture Research and Teaching farm to assess the reproductive performance of Archachatina marginata fed Leucaena leucocephala leaf powder as feed additive. ۲۰۸ adult snails were randomly partitioned into ۴ treatments and ۴ repetitions of ۱۳ comparable snails (weight and size). The Treatment T۰ (control) received only the experimental diet as described while three other treatments received not only diet but, Leucaena leucocephala leaf powder at ۰.۲۵%, ۰.۵% and ۰.۷۵%for a period of ۱۲ weeks. In each treatment, every morning, the substrate of each breeding bucket was stirred entirely and minutely to collect the eggs to determine the laying and morphometric characteristics of the eggs. The eggs were then placed ۱۰cm deep in loose soil substrates until hatching to evaluate the characteristics of the fertility. The unhatched eggs were broken, and the state of embryonic development observed to determine early embryonic mortality rate and late embryonic mortality. At the end of the experiment, animals of each replicate were sacrificed; the hemolymph was collected determine the total cholesterol and protein. The results showed that the characteristics of reproduction were affected with graded level of Leucaena leucocephala. The highest number of eggs laid (۱۷.۲۹±۱۳.۴۴) and the number of clutches (۲۶۸.۹۱) was recorded in animals receiving ۰.۵% Leucaena leucocephala in the diet while the highest value of fertilization rate (۹۵.۵۰±۸.۸۰), hatch rate (۹۴,۵۵±۹.۳۶), and hatchability (۹۸.۹۹±۳.۱۵) was registered in the treatment that received ۰.۷۵%. The highest value of total protein and cholesterol was recorded in the same treatment. In conclusion ۰.۷۵% of Leucaena leucocephala can be added in the diet of adult snail.The study was carried out at the sub-station of the Faculty of Agriculture Research and Teaching farm to assess the reproductive performance of Archachatina marginata fed Leucaena leucocephala leaf powder as feed additive. ۲۰۸ adult snails were randomly partitioned into ۴ treatments and ۴ repetitions of ۱۳ comparable snails (weight and size).
