http://sjournals.com/index.php/sjva <p>Scientific Journal of Veterinary (SJV)is a high-quality peer-reviewed well indexed scientific journal publishing original research findings on all aspects of veterinary sciences. Scope of the journal includes: pathology, microbiology, parasitology, physiology, pharmacology,veterinary medicine.</p> Sjournals en-US Scientific Journal of Veterinary Advances 2322-1879 http://sjournals.com/index.php/sjva/article/view/1798 <p>The study was carried out at the sub-station of the Faculty of Agriculture Research and Teaching farm to assess the reproductive performance of <em>Archachatina</em> <em>marginata</em> fed <em>Leucaena</em> <em>leucocephala</em> leaf powder as feed additive. 208 adult snails were randomly partitioned into 4 treatments and 4 repetitions of 13 comparable snails (weight and size). The Treatment T0 (control) received only the experimental diet as described while three other treatments received not only diet but, Leucaena leucocephala leaf powder at 0.25%, 0.5% and 0.75%for a period of 12 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 10cm 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 <em>Leucaena</em> <em>leucocephala</em>. The highest number of eggs laid (17.29±13.44) and the number of clutches (268.91) was recorded in animals receiving 0.5% <em>Leucaena</em> <em>leucocephala</em> in the diet while the highest value of fertilization rate (95.50±8.80), hatch rate (94,55±9.36), and hatchability (98.99±3.15) was registered in the treatment that received 0.75%. The highest value of total protein and cholesterol was recorded in the same treatment. In conclusion 0.75% of <em>Leucaena</em> <em>leucocephala </em>can be added in the diet of adult snail.</p> Tchowan Guy Merlin Ndum Gorreti Tufoin Tchoumboué Joseph Ngoula Ferdinand Copyright (c) 2024 Tchowan Guy Merlin, Ndum Gorreti Tufoin, Tchoumboué Joseph, Ngoula Ferdinand https://creativecommons.org/licenses/by-nc-nd/4.0 2024-04-20 2024-04-20 12 1
