Abstract Nigeria’s main sources of animal protein are fish, livestock and bush

meat. However, livestock production is not sufficient to meet the national

meat requirement, and there is the need to develop other sources of acceptable meat in addition to conventional livestock. The snail (Archachatina fulica ) is an important source of meat and is acknowledged to be the preferred meat virtually throughout Nigeria and the West African *Corresponding Author: Sub-Region. The demand for snail meat in Nigeria is high with its accompanying price hikes, making the prospect of snail rearing very bright Ahaotu E.O and encouraging either as a full-time or part-time job. The study therefore recognized the following features of snail production in the Njikoka Local Email: [email protected] Government Area of Anambra State; average stock size of 42 snails, with

Also, three-tier cage made with wood and Received: 15/01/2019 mesh dominated types of cage used by as much as 80%, with concrete cage Accepted: 12/02/2019 and other making up for 18% and 2%, respectively. Ninety percent of the farmers used indoor housing system, and the remaining 10% used outdoor system. Again, 91% and 9% of the respondents utilized family labour and hired labour, respectively. Income generation served as the main motive for snail production by about 63% of the respondent, with about 21% and 9% declaring employment and environmental conservation respectively as the

1. Introduction Snail meat (Smeat) has been consumed by Snails are bilaterally symmetrical invertebrates humans throughout the world (Ahaotu, 2016). The with soft-segmented exoskeleton in the form of interest in snail farming around the world comes from calcareous shells. In West Africa, snails dwell mostly snails’ high quality protein and medicinal value. in humid forest areas from where these are gathered by Protein from snail meat is said to be very rich in all villagers for consumption and other uses (Onuigbo, essential amino acids such as Lysine, Leucine, arginine 2015). The meat has traditionally been a major and tryptophan. Smeat has been found to be higher in ingredient in the diet of people living in high forest protein content (37 - 51%) compared to that of guinea zone. Agbogidi et al. (2008) also reported that snails pig (20.3%), poultry (18.3%), fish (18%), cattle are high in protein, iron and low in fat. Ahaotu et al. (17.5%), sheep (16.4%) and swine (14.5%). Iron (2015) noted that snails contain almost all the amino content (45 - 59 mg/kg), low in fat (0.05 - 0.08%), acids required by man. Snails belong to a division of sodium and cholesterol level (Bayode, 2009). The the animal kingdom called Mollusca. Mollusca liquid obtained from snail has high iron content and is constitute one of the major divisions of the animal used for treatment of anemia, hypertension and poor kingdom (Ademosun and Omidigi, 1999). There are sight. The formulations from this liquid can be used to probably over 100,000 living species and those animals treat burns, abscesses and other wounds, measles, small have adapted themselves to practically every available pox and some skin diseases (Bayode, 2009). Smeat is environmental condition. recommended in the past for treatment of ulcer and asthma.

Much of the snails marketed in Nigeria prospective snail farmers. Over 80% of Nigerian are collected from the wild.

To avert danger of malnutrition, probably attributed to lack of awareness of the especially among children, the giant African land snail economic potentials of this micro livestock (Ahaotu et is a good substitute of source of protein (Bayobe, al ., 2014; Anyalebechi, 2015).

Durunna et economic venture among farmers in Njikoka local al. (2015) reported that snail breeding can start at any government area of Anambra State, Nigeria. The time of the year under domestication, but the time to specific objectives are to describe the features of snail start breeding snail is at the beginning of the rainy farming in the Njikoka Local Government Area of season when feeds of snail are available. The Anambra State, to determine the costs and returns foundation stock may be from the following sources: associated with snail production, to ascertain the snail farmers, research institutes or direct collection profitability and viability of snail production, to from the forest or bush.

The mean annual temperature over Snails feed on a wide variety of food mostly in most of the region is about 27 ºc. the night at dusk, snails are nocturnal and crepuscular. They may feed during the day when it rains or there is very dark cloud (Akintomide, 1997). The advantages of snail farming (heliculture) over most other livestock includes low capital requirements, for its establishment and operation, less demand for professional knowledge, very high fecundity and low mortality, less labour requirement, and availability of ready domestic and international markets among others (Akinbile, 2000). Some constraints that militate against good performance of snail includes genetic constituent, hormonal influence, environmental factors, rearing pattern and inefficient use of resources available to the farmers as was observed by Akinbile (2000). In spite of the potentials and advantages of snail farming Fig 1: Map of Njikoka Local Government Area of (heliculture), widespread participation in its production Anambra state, Nigeria. by farmers has not been achieved in Nigeria (Baba and
