This is because natives prefer to eat the dark-skinned ones, based on the belief that they are tastier and that there is something undesirable or freakish about the white-skinned ones. Medium-sized and moderately broad, up to 110 mm. This research therefore aimed at comparing the effect of roughage and concentrate feed with Moringa oleifera, Leucaena leucocephala, and Gliricidia sepium leaf meal inclusion in snail diet on reproductive attributes of Archachatina marginata.

The development of the embryo is heavily affected by soil temperature and moisture. [1] How the species reached Martinique is unknown, but they may have been intentionally introduced as "pets" or by workers returning from West Africa.[2]. [citation needed], For the above reasons, keeping achatina species as pets in North America is controversial due to invasive spread of similar species into the United States. The snail is one of West Africa's largest known terrestrial snails. Pseudachatina colorata. Therefore the terrarium size should be 100x50x50 cm. Apex pale coloured or roseate. Ingesting uncooked contaminated intermediate or paratenic hosts or vegetables contaminated with third stage larvae can infect humans (dead end hosts) (Chatterjee 2009).

At an air temperature of 26-28C and an inch below the soil surface 17-19 the incubation time is 35-41 days. The nerves produce warm responsive fibers when the temperature exceeds 25C and produce cold responsive fibers when the temperature falls below 19C. In Cameroon it can be found aestivating under ground during the drier months, having a closed aperture, sealed with a solid, calcareous, white epiphragm. Ingestion of raw or undercooked contaminated mollusks, crustaceans, or other hosts, as well as vegetables contaminated with infectious larvae, can cause infection. A thermostatically controlled forced-air oven was used to analyse the . Ejidike and Afolayan (2010) pointed out that the availability of acceptable snail feed could contribute a lot in encouraging interest in snail farming, thereby mitigating the current acute animal protein shortage. The lower temperatures there may mean that eggs in captivity do not have to be so uniformly warm as is known to be the case for "ovum" in particular.2. The nematode Rat Lung Worm (Angiostrongylus cantonensis) uses this snail as an intermediate host. and Okeke GC (2003). as suggested in a french study, see further reading for translation.)

On So Tom it has become widespread and Gascoigne (1994) suggested that competitive interactions, along with habitat destruction, may have contributed to the decline in the indigenous Archachatina bicarinata (Bruguire)." PubMed Central Proceedings of the 27th Annual Conference of Nigerian Society of Animal Production; Mar 1721; Akure, Nigeria: Federal University of Technology. The parasite was found to be most prevalent in small snails (52.94%), followed by medium sized snails with a frequency of 29.41%, and the giant-sized snails with the lowest prevalence of infection. Eggs: The lemon-yellow eggs are slightly smaller than nominate race, being 17.5 to 18 mm. Their range stretches all the way down to the Orange River in South Africa (Hodasi 1998). The snails shells were cracked with stone and the internal parts were separated into Stomach, Crop, Kidney, Haemolymph, Mantle, Digestive gland and foot were put in a separate petri dish containing 0.85% of NaCl solution, the forceps were used to tease the parts and samples were taken randomly from each petri dish using a pipette. The main visceral nerve is on the snail's back and connects to a large group of nerve cells to transmit information in the body. were assessed for their proximate and mineral compositions aimed at establishing their nutritive values on wet weight basis. However, the gonadosomatic index of snails on herbs and roughage treatment was better than snails on concentrate without leaf meal inclusion. The concentration of Pb in Achatina achatina and A. marginata from Ikire, and Cd in . One hundred fifty points of lay snails weighing between 150 and 170g were randomly allotted to 5 treatment diets with three replicates, ten snails per replicate, designated as treatment 2 (GNCD) which has groundnut cake, treatment 3 (GLLM) has Gliricidia sepium, treatment 4 (MOLM) has Moringa oleifera, and treatment 5 (LLLM) has Leucaena leucocephala leaf meals as protein source in snail diet and a control (treatment 1) (UPWP) fed on roughage (unripe pawpaw and watermelon peel) in a 12-week feed trial. wide but have been known to reach 135 mm (and possibly higher [148 mm.] subsuturalis (Hidalgo, 1910), The highest prevalence of infection was found on the infected snails' mantle, followed by the digestive gland, kidney, and stomach; no infection was found on the crop, haemolymph, or foot.

Archachatina marginata is the largest of the Archachatina snails and is found in West Africa. OSB carried out laboratory work, data analysis, the interpretation of results and developed the manuscript. The reproductive ability of snails is predicted by the gonadosomatic index; this explains the high gonadosomatic index of snails on leaf meal-based diet accompanied with better reproductive output in laying snails. 2020), did not infect snails. J. Agric. However, the standout performer is snails fed with Leucaena leucocephala-inclusive treatment, judging by their egg production, fertility, hatchability, and juvenile snails accompanied with gonadosomatic index. Captive individuals should also be supplemented with a source of calcium and other vitamins (such as is found in reptile turtle pellets, etc.). The result revealed snails fed with UPWP had the least final weight and weight gain which was accompanied by the highest feed intake across the treatments. Snail production in Nigeria, like most mini-livestock, is largely rudimentary, and its demand is met by hunting from their habitat in the wild.
