The study was carried out at the Niger Delta University, Faculty of Agriculture Teaching and Research Farm, Bayelsa State. A total of Ninety six (96) growing snails (Archachatina marginata). Using Plantain peel as an additive, four diets were formulated at the levels of 0%, 3%, 6%, and 9% to form the treatment diets. The experiment lasted for eight (8) weeks during which the weight gain, feed intake, shell width, shell length, shell thickness and hematological parameters were obtained. The weight gain, shell width, shell length and shell thickness are not significantly different (p<0.05) whereas, the feed intake differed significantly (p<0.05) for all the treatment diets in the experiment. From the results, it was concluded that concentrate with 0% inclusion of Plantain peel meal was suitable for snail diets as it gave the best performance. The hematological parameters measured in the African giant land snails are White blood cell, Neutrophile and Lymphocyte differed significantly (p<0.05). Plantain peel can serve as source of potassium for other animals, as the highest percentage of potassium was found in the hemolymph of snails fed with 9% inclusion of plantain peel. It is recommended that; there should be no inclusion of plantain peels in the diet of the African giant land snails in order to achieve higher weight gain and feed intake.

African gaint land snails are important as means of alleviating acute protein shortage in Nigeria livestock Industries. The present study aimed to study the influence of intensive and extensive management systems on the growth Performance of adult African Giant Land Snails (Archachatina marginata) was carried out in the wildlife domestication unit of the Department of Forest Resources and Wildlife Management, University of Benin, Benin City, Nigeria. Ninety  African giant land snails (A. marginata) of average body weight 160.31g ± 0.38g were used for the study. The snails were grouped into two- Group A and Group B. 45 snails in group A were raised in an intensive system of management while 45 snails in group B were raised in an extensive system of management. The data collected on weight gain, shell length increment and shell width increment during the experiment were subjected to student t-Test at 5% significant level. Results showed that there was a significant difference at (p<0.05) in the weight gain. The intensive management system had a higher weight gain of 128.96g with mean value of 4.96 while the extensive management system had a weight gain of 88.37g with mean value of 3.40. There was no significant difference at (p>0.05) in the shell length increment. The snails in the extensive management system had the higher shell length increment of 5.32cm with mean value of 0.20 while the snails in the intensive management system had a shell length increment of 2.43cm with mean value of 0.09. There was a significant difference at (p<0.05) in the shell width increment. The snails in the extensive management system had the higher shell width increment of 9.31cm with mean value of 0.36 while the snails in the intensive management system had a shell width increment of 4.30cm with mean value of 0.17. The snails in the intensive system had a Feed Conversion Ratio of 5.03. For better growth performance of A. marginata in terms of weight gain, snail farmers should raise their snails in an intensive system of management and formulated diet should be used in feeding the snails along side with natural feed such as leaves and fruits.

Feeding Regimes

Effects of various feeding regimes on the growth performance of the giant African land snail, Archachatina marginata were studied using one hundred and twenty (120 Juvenile snails) weighing 0.66g +1 per snails for a period of 90 days. The treatments were. T1 -Grower starter, T2 - Grower mash, T3 - cocoyam and cassava leaves and T4 - Ripe pawpaw fruits. The Completely Randomized Design was used with four treatments and each replicated three times. The snails were confined in wooden hutch boxes. Data was collected on weekly body weight feed intake, shell length and shell width. Results obtained showed that snails fed with broiler starter diet (T1) had significantly (P<0.05) higher performance in terms of weight gain, feed intake, shell length and the aperture, while pawpaw fruits T4 recorded the least values. The highest values for feed intake was observed in T1 (135.5g) followed by T2 (78.2g), while the least feed intake was observed in T4 (55.7g). Snails fed with T1 recorded the highest weight gain (60.1g) followed by T2 and T3.The lowest weight gain was obtained in T4 (37.9g). Shell length was highest in T1 (20.7mm), closely followed by T2 (19.2mm). The aperture recorded the highest mean values in T1 (20.1mm). The least operculum was recorded in T4 (12.9mm). Therefore, the broiler starter T1 should be used to feed growing snails to improve their performance.

Abstract. The effects of naturally acidified seawater on shell traits were quantified through the comparison of dove snails (Family: Columbellidae) Anachis misera from vent environments with Euplica sp. from non-vent sites in northeastern Taiwan. Samples of A. misera were collected around a shallow vent (24.8341° N, 121.96191° E), which included the east, south, southwest, and northwest sites. An absence of Anachis snails was found in the most acidic north site (pH 7.19–7.25). Based on the similarities of protein expression profiles, the Anachis snails were classified into two groups, i.e., V-South (pH 7.78–7.82) and V-Rest (pH 7.31–7.83). Comparing their shell traits to the non-vent Euplica sp. from Da-xi (DX) and Geng-fang (GF) (pH 8.1–8.2), a difference in shell shape (shell width : shell length) was found, with the populations having more globular shells than the non-vent ones. The means of shell width were significantly different among sites (p < 0.01), with a descending order of GF > DX > V-South and V-Rest. The relationships of shell length to total weight were curvilinear for both Anachis and Euplica snails. The logarithmically transformed slopes differed significantly among sites, and the mean body weight of the GF population was greater than that of the others (p < 0.01). Positive correlations between shell length and shell thickness of body whorl (T1) and penultimate whorl (T2) were only observed in non-vent GF and DX populations. Anachis snails from vent sites were thinner in T1 and T2 compared to the Euplica snails from non-vent sites (p < 0.05). Within each vent group, shell thickness between T1 and T2 was insignificantly different. Between vent groups, T1 and T2 from V-Rest showed a decrease of 10.6 and 10.2%, respectively, compared to V-South ones. The decrease of T1 and T2 between vent Anachis snails and non-vent Euplica snails was as great as 55.6 and 29.0%, respectively. This was the first study to compare snail's morphological traits under varying shallow-vent stresses with populations previously classified by biochemical responses. Overall, the shallow-vent-based findings provide additional information from subtropics on the effects of acidified seawater on gastropod snails in natural environments.

A 56 - day feeding trial was conducted to evaluate pineapple crush waste (PCW) as dietary fibre source in broiler diets. Five straight diets were formulated to contain the PCWat dietary levels of 0%, 2.5%, 5.0%, 7.5% and 10.0% as replacement for wheat offal. One hundred and fifty (150), day-old "Anak 2000" broiler chicks were randomly allotted to the 5 diets containing three replicates per treatment with 10 chicks per replicate in a completely randomized design (CRD). The final body weight, daily weight, daily feed intake and daily protein intake were generally higher in the birds fed diet 2 (2.5% PCW). There were significant (P<0.05) differences in daily feed intake and daily protein intake between the group on diet l and the other groups, while daily weight gain, feed conversion ratio and protein efficiency ratio were statistically the same (P >0.05) across the treatments. Digestible crude fibre values significantly (P < 0.05) decreased with increasing levels of PCW in the diets while the other digestibility percentages were comparable (P >0.05) in all dietary treatments. Values for the hematological parameters and blood serum chemistry did not deviate (P >0.05) statistically from established normal values for chicken. However, liver weights significantly increased (P < 0.05) across the dietary treatments while other organs observed did not differ significantly (P >0.05) in weight across the treatments. Cost per kg feed decreased as the level of PCW inclusion in the diets increased while the cost per kg weight gain showed that birds sed on diet 4 (7.5% PCW) were the most economical to produce. The results suggest that PCW could replace wheat offal in broiler diet up to 10.0% as a dietary fibre source without any deleterious effect.

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

In order to preserve and conserve the Giant African Land Snails, a study was carried out between September 2015 and January 2017 at the University of Buea (South-West Region, Cameroon), to assess the effect of protein level on the characteristics of growth of Achatina achatina in captivity. 90 young snails of one month old, weighing between 1 and 1.5 g, of shell length between 15.5-23.85 mm and shell diameter between 12.60-16.85 mm and free from wounds or shell defects were divided into 3 groups of 5 snails each and 6 replicates in cages equipped with feeders and drinking troughs. Each treatment was randomly assigned to one of the experimental feed with variable protein levels (20, 22 and 24%) in addition to pawpaw leaves as a staple feed. These were previously weighed as well as the remnants using a 0.5g precision balance. The cultured substrates were watered daily (0.50 liter/substrate). At the beginning of the test, and then every week, the snails were weighed, and shell measurements done using a digital caliper of 0.05 mm accuracy. The animals were monitored for fourteen months. The results show that feed intake (3.01±1.57), weight gain (24.50±5.72), daily weight gain (0.058±0.016), gain of shell length (30.26±4.19) were significantly higher (P < 0.05) in snails receiving 24% protein in the diet compared to snails from the other treatments. The highest consumption index was recorded in snails receiving 20% protein in the diet but the statistical analyses did not find any significant difference. In conclusion, the protein level of 24% can be retained in the diet of growing snails.

The scarcity and increasing cost of conventional plant protein sources prompted researches into potential feed resources that are relatively of less importance to man. Loofah gourd (Luffa cylindrical (M.J. Roem) is a plant that is widely available in most tropical, subtropical and temperate region. In Nigeria it grows luxuriantly uncultivated and the sponge is often used for domestic cleaning while the seeds are discarded. The seeds were de-hulled, milled and fed at 0, 5, 10, 15, and 20% dietary levels of inclusion as partial total replacement for groundnut cake. One hundred and fifty (150) day-old broiler chicks were divided into five (5) groups and each was fed the experimental diets for fifty six (56) days in a completely randomised design (CRD) arrangement. Data collected included the average feed intake (AFI), average weight gain (AWG), live weight (LW) feed conversion ratio (FCR), protein efficiency ratio (PER), haematology indices such as pack cell volume (PCV), red blood cell count (RBC), white blood cell count (WBC) and haemoglobin (Hb), serological variables such as Alanine aminotransferase (ALT), aspartic aminotransferase (AST), alkaline phosphatase (ALP) and carcass characteristics. Loofah gourd seed meal (LGSM) significantly (P<0.05) depressed the feed intake, weight gain, live weight, and protein efficiency ratio of the birds as the dietary inclusion of LGSM increased in a similar trend. AFI, AWG, and PER were significantly highest (P<0.05) in birds on the control group (125.88 g/day, 51.37 g/day, and 1.81 respectively) and lowest in those on 20% LGSM (62.88 g/day, 19.35 and 1.39 respectively). PCV and Hb were significantly highest (P<0.05) in birds on the control group (10.46 g/dl and 34% respectively) and lowest in those on 15% LGSM (21%) and 10%LGSM (6.98g/dl) respectively. Birds fed with the control diet had the lowest (P<0.05) AST (86.13 U/I), ALT (5.67 U/I) and ALP (112,338.90) and those on 20% LGSM had the highest AST (104.18 U/), ALT (10.98 U/D while the highest ALP (201,762.90) was in birds fed 10% LGSM. Weight of liver and spleen expressed as percentage of live weight were significantly lowest in birds on the control group (1.38 and 0.18 respectively) and highest in those on 15% LGSM (4.08 and 1.50 respectively). The increase in liver and spleen weight coupled with increased serum enzymes activities suggest the presence of anti-nutrient in LGSM. Hence, the use of LGSM beyond 5% level of inclusion is not beneficial in the production of broiler.

The study was carried out to assess the performance characteristics and blood profile of growing rams fed mixture of bamboo leaves and neem seed cake. Eighteen West African dwarf rams with an average weight of 8.00±0.20kg and aged between 8-9 months were randomly allotted to three dietary treatments with six animals per treatment group in a completely randomized design. The diets compared were TD1 (70% Guinea grass with 30% concentrate diet which was the control group), TD2 (mixture of 50% bamboo leaves with 20% neem seed cake and 30% concentrate diet) and TD3 (combination of 45% bamboo leaves with 25% neem seed cake and 30% concentrate diet). The results obtained indicated that average total feed intake (11.13kg), average daily feed intake (132.50g), mean corpuscular haemoglobin concentration (33.35g/dL), glucose (59.01mg/dL), cholesterol (42.89mg/dL), creatinine (1.01mg/dL) and urea (13.73mg/dL) were significantly (P<0.05) better with animals on TD1 . Animals on TD2 had the highest values in terms of finial body weight (11.33kg), average total weight gain (3.27kg), average daily weight gain (38.93g), total digestible nutrient (68.97%), packed cell volume (30.06%), haemoglobin (10.68g/dl), red blood cell (9.42 x 106/.ml), mean corpuscular haemoglobin (11.70Pg), total protein(8.09g/dL), albumin (3.03g/dL), and globulin (5.06g/dL). Feed conversion ratio (4.27), mean corpuscular volume (30.95fl) and white blood cell (2.56 x 103/mL) were significantly highest for animals on TD3. No significant (P>0.05) difference existed between the experimental rams with regards to initial body weight, lymphocyte, neutrophile. It was concluded that combination of 50% bamboo leaves with 20% of neem seed cake and 30% concentrate diet improved performance, haematological and serum biochemical indices for growing rams

A six week feeding trail was conducted to investigate the effect of honey on the performance and haematological parameters of broilers and Nigerian Local Chickens. The experiment was conducted at the Niger Delta University, Faculty of Agriculture Teaching and Research Farm. Sixty (60) day old chicks which consisted of three treatments, 20 broilers, 20 normal feather and 20 naked neck genotypes were used with each of the genotype having control. Feed and water were given ad-libitum. The experimental birds for the broiler and naked neck genotypes had the highest significant values compared to the control which had significant difference (P<0.05) in their performance, while the control of the normal feather genotype had the highest significant values compared to the experimental birds but there was no significant difference (P>0.05) in their performance. The broiler birds had the highest significant values compared to normal feather and naked neck genotypes and there was a significant difference (P<0.05) in their performance. The effect of honey on haematological parameters showed that there was a significant difference (P<0.05) in White blood cell, neutrophils, lymphocyte, monocyte, eosinophile and basophile of broiler birds, in normal feather, white blood cell, neutrophile and lymphocyte differed significantly (P<0.05) and there was a significant difference (P<0.05) in neutrophile and lymphocyte in the experimental and control for naked neck genotype. In conclusion, the study revealed that the inclusion of honey caused a positive effect on the performance of broilers and naked neck, but showed no effect or reduction in performance in normal feather genotype.

Abstract Two new, extremely small land snail species, Angustopila coprologos Páll-Gergely, Jochum & Hunyadi n. sp. and Angustopila psammion Páll-Gergely, Vermeulen & Anker n. sp. are described from northern Vietnam and northern Laos, respectively. The former is characterized by a rough surface sculpture and bears tiny mud granules arranged in a pattern of radial lines on its shell surface. The latter species is the new global record-holder of the tiniest land snail title, with a shell width of 0.6–0.68 mm and a shell height of 0.46–0.57 mm. These measurements surpass the former records of Angustopila pallgergelyi and Acmella nana.
