Abstract:
The experiment was conducted to determine the changes in the biophysical parameters during starvation in three common species of land snails identified in Edo and Delta States. A total of 252 matured healthy snails comprising three species (Archachatina marginata, Archachatina papyracae and Achatina fulica) were used. A completely randomized design was used in a 3 x 4 factorial arrangement. At the end of two weeks acclimation period, feed and water were withdrawn for 4, 8 and 12 weeks. Result shows that A. marginata has significantly (P<0.05) highest initial liveweight. A. papyracae had the least weight but was not significantly (P>0.05) different from the weight of A. fulica used in the study. During the 12 weeks of starvation, A. papyracae recorded the highest mortality rate of 24.58 %. A. marginata and A. fulica respectively recorded mortality rate of 9.05 and 6.52 %. A marginata reflected two stages of major weight decline; 2nd and 9th weeks. The A. papyracae and A. fulica however declined conspicuously only at the 1st week. The weight of the muscular foot which constitutes the edible portion of the three species decreased between 0, 4 and 8 weeks. There were no significant differences in weight in each of the three species. Twelveweeks aestivation eventually resulted in further and significant weight loss. The aestivation lengths did not affect the shell weight in the three species, except A. marginata with significant decline at the 12th week. This study indicates that A. marginata and A. fulica are bigger in size and more tolerant to extended starvation than A. papyracae.

Abstract:
The Giant African Land Snail is one of the largest land snails in the world. In Nigeria, farmers still can not identify the breed Archachatina marginata (Am) and its varieties. In this study, Archachatina marginata varieties were characterized using qualitative characters. A total of 304 animals comprising of 93 Archachatina marginata marginata (Amm), 163 Archachatina marginata suturalis (Ams) and 48 Archachatina marginata ovum (Amo) was used. Five qualitative parameters were collected on each snail and recorded. These parameters are shape of snail (SS), shell colour (SC), colour of labium (CL), foot colour (FC), number of whorls (NW). Data were analysed using simple descriptive statistics; frequency counts and percentages. The orange labium was more than white labium. 87.0%, 86.50%, 77.08% was orange labium in Amm, Ams and Amo respectively. 70.96% of Amm had brown foot, 54.16% of Amo had brown foot, 50.92% are black foot and 49.08% brown foot in the Ams All the varieties were sinistral (100%) in shape. 100% of the shell colour of Amm was yellow shell with black straight streaks. 52.69%, 68.08%, 64.58% had 3+2 whorls in Amm, Ams and Amo respectively. This study has revealed that these snails can be identified by these qualitative characteristics apart from shell colour. The labium and foot colour can be used to identify these varieties. The labium and foot colour has also indicated that there are still variations among the varieties. Therefore, there is a need for further studies on these varieties of Archachatina marginata.

Abstract:
A study was conducted to evaluate the effects of utilisation of three leafy vegetable diets (bitter leaf Vernonia amygdalina, fluted pumpkin leaf Telfairia occidentalis and pawpaw leaf Carica papaya) on the growth performance of giant West African snail Archachatina marginata. A total of 90 A. marginata were used for the study. 30 snails were also subjected to three different dietary treatments in three replicates of 10 snails per replicate and fed with the fresh leaves of these vegetables over a period of 12 weeks. Results obtained recorded significant differences (P < 0.05) in terms of weight gain, shell length, shell circumference and shell thickness. On the whole, Archachatina marginata fed on fluted pumpkin leaf performed better in terms of mean weight gain when compared with those fed on bitter and pawpaw leaves. On the other hand, snails fed on pawpaw leaf had the best mean shell length gain, mean shell circumference and mean shell thickness when compared with those fed on bitter and fluted pumpkin leaves. The result clearly showed that the tested leafy vegetables can be successfully utilised as diets for rearing of A. marginata. For farmers to achieve better result, the inclusion of fluted pumpkin and pawpaw leaves in the diets of Archachatina marginata is highly recommended in snail rearing businesses.

Abstract:
A comparative study of the gametes of two species of Giant African Land Snails; Archachatinu marginata and Achatina achatina was carried out. Three groups of snails weighing 80-100,101-150 and 151-250 g were used in a 3x2 factorial design, with 5 replicates, involving a total of 30 snails. Albumen gland, little hermaphrodite duct, spermotheca and ovo-testis were examined for the presence of ova and spermatozoa. The morphology of the spermatozoa and ova of both species Was studied. Ova were found in the albumen gland and ovo-testis. Spermatozou were only found in the little hermaphrodite duct. Spermatozoa head and tail lengths were not significantly (P>0.05) different between species, while the mid-piece length was significantly (P<0.05) different. Liveweight group 101-150 g had the highest number of spermatozoa and ova count in both species. Morphologically, spermatozoa head, collar and mid-piece crest differed between species Archachatina marginata spermatozoa had pointed head, longer collar and highest number of mid-piece crests compared to Achatina achatina. Ova seen in the ovo-testis of A. marginata were larger compared to those seen in A. achatina. It was concluded from the study that there are differences in the morphology and dimensions of their germ cells.

Abstract:
This study focused on the evaluation of the effect of soil moisture on the feed intake and weight gain of the Giant African Land snails, Achatina achatina and Archachatina marginata in different seasons using a 2 x 2 x 4 factorial experiment with soil moisture at two levels (low 25ml of water/ week and high 100ml water/week), species at two levels (Achatina achatina and Archachatina marginata) and season at four levels (cold dry, hot dry, hot wet and cold wet) constituting the three factors. Result showed that there was a significant seasonal differences (P<0.001) for weekly feed intake of snails in which values of 3.85, 2.53, 3.88 and 4.44g were recorded in cold dry, hot dry, hot wet and cold wet seasons, respectively. Monthly weight gains of 5.41g recorded for Archachatina marginata was significantly higher (P<0.001) than the value of 1.94g recorded for Achatina achatina. There was significant interaction (P<0.001) between soil moisture level and species on monthly weight gains of the snails. The feed intake and weight gain of snails (4.28 g and 6.43 g) in the high soil moisture treatment was significantly (P<0.01) higher than those in the low soil moisture treatment (3.07 g and 5.30 g). In conclusion, it is evident that species, season and soil moisture level affected the feed intake and weight gain of the Giant African Land Snails

Abstract:
The cost of procuring meat as an animal protein source in Nigeria is on the increase. There is therefore the need to source for alternative cheap source of animal protein that can serve the populace the nutritive value needed in the body system. The study was carried out to assess the proximate composition and mineral analysis of the two species of snail meat (Archachatina marginata and Achatina achatina) in Odeda Local Government Area of Ogun State Nigeria. The result revealed that snail meat (Archachatina marginata and Achatina achatina) were found to contain; 0.16g/100g and 0.18g/100g of Crude fibre, 1.43g/100g and 0.79g/100g of Ash content, 1.53g/100g and 0.88g/100g of Ether extract, 22.75g/100g and 11.92g/100g of Crude Protein, 0.09g/100g and 0.19g/100g of NFE (Nitrogen Free Extract), 74.06g/100g and 86.1g/100g of moisture content respectively while the mineral content of snail meat (Archachatina marginata and Achatina achatina) was found to be 1.216mg/g and 1.343mg/g of Phosphorus, 0.426mg/g and 0.438mg/g of Magnesium, 0.084mg/g and 0.093mg/g of Iron, 2.011mg/g and 2.046mg/g of Calcium, 1.934mg/g and 1.967mg/g of Potassium, 0.795mg/g and 1.000mg/g of Chlorine. The overall nutritional potential of the two species was quite good. These results show that these species of snail are highly nutritive. The findings were discussed in line with the importance and implication of the uses of edible land snail meat to man. It is therefore recommended that there is need to increase animal protein production in Nigeria and other developing countries of the world as a panacea to imminent problem of malnutrition.

Abstract:
This study was to evaluate the growth response of Archachatina marginata as influenced by four natural diets: Pawpaw (Carica papaya) cocoyam (Colocasia esculenta), cocoyam (Xanthosoma sagittifolium), and cassava (Manihot esculenta) leaves and growers mash (a compounded ration). One hundred and twenty (120) grower snails (Archachatina marginata) were purchased from a farm in Ibadan, Oyo State. Data were collected on the growth parameters (weight, length and circumference of shell of the snails arranged in a Completely Randomized Design and replicated three (3) times. The results showed that pawpaw (Carica papaya) recorded the highest mean in all the parameters measured and throughout the duration of the experiment. Cocoyam (Colocasia esculenta) leaf had a better mean than the Cassava (Manihot esculenta) leaves in terms of weight gained whereas the reverse is the case in terms of length and circumference of shell. Pawpaw (Carica papaya) is therefore, recommended to both local and small scale farmers in Abia State and in Nigeria for feeding their snails and cocoyam (Colocasia esculenta) leaves and growers mash as an alternate feed.

Abstract:
There is inadequate information on quality feedstuff for large scale production and all year round availability of snails in Nigeria.The research was conducted to investigate the organoleptic properties of the African giant land snails (Archachatina marginata). Thirtytwo snails were randomly allotted into four dietary treatments of varied levels of 0%, 5%, 10% and 15% rumen content inclusion. Each treatment was replicated with four snails per pen in a completely randomized design. The snails were reared in mini paddock. Feed and water were supplied ad-libitum. At the end of the eight weeks period of feeding trials, two snails were harvested at random from the replicates of each of the four treatments, sacrificed, processed and analyzed. Based on appearance, taste and aroma of the snails fried and stewed with spices and the other one steamed with spices, preference ranking in descending order revealed 15% (6·85) rumen content inclusion had the highest mean preference followed by 5% (6·53) inclusion for the fried snail with spices and 0% (6.65) inclusion had the highest ranking followed by 15% (6.53) rumen content inclusion for the snail steamed with spices. The treatments had no appreciable effect on the nutrient composition and sensory quality of the snail meat. It can be concluded that growing snails can utilize rumen content inclusion thereby increasing the feed data base for snail production in the Tropics.
