SNAIL: THE WEALTH IN THE TROPICS: A REVIEW

This review emphasized the prospect of snail production as a means of generating wealth in Nigeria, especially now that unemployment is on the increase. After the Coronavirus disease 2019 (COVID 19) lockdown, the price of foodstuffs (inflation) and the exchange rate of the Nigerian Naira to the US Dollar soared, making many households unable to …

The effect of the nutrient composition of maize chaff and pawpaw fruit-based diets on growth performance and carcass yield of giant African land snail (GALS) was investigated. The feeding trial was for 56 days. A total of two hundred and forty (240) grower snails with an initial average weight of 64.06±0.19g were randomly selected into …

EFFECTS OF STARVATION ON MINERAL CONTENT OF HAEMOLYMPH AND PROXIMATE AND LIPID PROFILE OF FOOT MUSCLE OF GIANT AFRICAN LAND SNAIL, ARCHACHATINA MARGINATA

Unfavourable environmental conditions such as extreme dryness expose snails to acute starvation. This study investigated the effects of starvation on the mineral profile of the haemolymph and lipid profile of foot muscle in the giant African land snail, Archachatina marginata.

IMPACT OF SNAIL SIZE ON REPRODUCTION AS AN ASPECT OF BREEDING AND MANAGEMENT OF GIANT AFRICAN LAND SNAILS: A REVIEW

[metadata element="custom_fields" ] ABSTRACT This paper reviewed the “impact of snail size on reproduction as an aspect of breeding and management of giant African land snails” in Nigeria. From the review, it could be stated that though snail size serves as a sign for sexual maturity of mates, it is not a good indicator of …

BIOCHEMICAL AND STRUCTURAL ANALYSES OF ALBUMEN GLAND OF THREE DEVELOPMENTAL STAGES OF GIANT AFRICAN LAND SNAIL, Archachatina marginata

The albumen gland of giant African land snails (GALS) is an elongated, tongue-like shaped organ that contains the fertilization chamber where the ova are fertilized and very rich in nutrients for embryo development.

WOUND HEALING EFFECT OF SHELL POWDERS OF THE DIFFERENT DEVELOPMENTAL STAGES OF GIANT AFRICAN LAND SNAILS (ARCHACHATINA MARGINATA) ON ALBINO WISTER RATS

Wound healing is the process of repair that follows injury to the skin and other soft tissues. Giant African land snail parts are useful in the treatment of diseases like anemia, hypertension, labor pain, constipation, and wounds.

EFFECT OF SITE OF COLLECTION AND LIVEWEIGHT ON HEMOLYMPH VOLUME AND SURVIVAL OF ARCHACHATINA MARGINATA

A study was conducted on the development of methodologies for lethal and non-lethal hemolymph collection in the giant African land snail (Archachatina marginata).

CONVENTIONAL AND UNCONVENTIONAL FEEDS IN SNAIL NUTRITION: A REVIEW

Feeding is one of the major factors affecting snail growth, egg production, and attainment of early maturity. Snails have been described as nocturnal that feed mainly in the night, at dusk, or by day when there is rain or if the sky is overcast.

GROWTH AND COST BENEFITS OF GROWING SNAILS FED DIET CONTAINING DIFFERENT LEVELS OF PROTEIN WITH THE SAME ENERGY LEVEL

The study was carried out to determine the growth performance and cost implications of feeding snails with different protein levels at the same energy level. A total of 150 snails of the same weight and breed were randomly allotted to 5 different groups.

EFFECT OF SHORT-TERM AESTIVATION DURATION ON STRESS AND REPRODUCTIVE HORMONES OF GIANT AFRICAN LAND SNAIL, Archachatina marginata

Snails are cold-blooded animals with soft body consisting of outer shell known as exoskeleton. Climatic conditions leading to changes in the environmental parameters such as temperature and humidity create physiological and biochemical adjustments, during this condition snails aestivate.

GROWTH PERFORMANCE OF GIANT AFRICAN LAND SNAIL (Archachatina marginata) FED VARYING DIETARY PROTEIN AND ENERGY LEVEL

A 10-weeks study was conducted to determine the effect of varying dietary protein and energy levels on performance of growing giant African land snail (GALS), Archachatina marginata. One hundred and forty-four snails with mean weight of 138.48g were used for this study.

ISOLATION AND IDENTIFICATION OF MICROORGANISMS ASSOCIATED WITH THE HAEMOLYMPH OF DIFFERENT GROWTH PHASES OF GIANT AFRICAN LAND SNAIL (Archachatina marginata)

Isolation, determination of microbial load and identification of microorganisms associated with haemolymph of the three stages of development of the giant African land snail Archachatina marginata was investigated in this study.

RELATIONSHIP BETWEEN THE COLUMELLAR MUSCLE AND COLUMELLAR OF GIANT AFRICAN LAND SNAIL (Archachatina marginata)

The columellar muscles originate from the columellar of the shell, attaching the body parts of snail to the shell and responsible for retraction in coiled gastropods. The attachment of the columellar muscle to the columellar enhances the performance of the columellar muscle.
