THE ROLE OF IRON IN PIGLET DEVELOPMENT.

Production methods have led to an impressive increase in 
productivity but have also increased iron needs in piglets. A potential iron gap can inhibit growth rates and 
profits significantly thus imposing threat can be eliminated simply by providing iron supplements/injections at early stages of development and over course of the piglet's life. Rapid development in modern swine production is a success , with piglets displaying incredible growth rates in their first weeks of life. However, the increased productivity has increased iron needs in piglets and, thereby, increased the risk of iron deficiency anaemia. Anaemia in piglets is a condition characterized by lack of haemoglobin in the body's red blood cells. Haemoglobin plays an important part in transporting oxygen from the lungs to the tissues of the body, and when the hemoglobin level is reduced, the body's access to the vital oxygen is reduced. The most common cause of anaemia in piglets is iron deficiency. Iron deficiency occurs when the piglet's own iron stores are depleted or when the exposure to stress conditions either inhibits the build-up of haemoglobin or increases the degradation of haemoglobin in the piglet. A critical time for iron deficiency is at weaning, when iron stores following the initial iron dextran injection in the first days of life may be depleted. The causes of low levels of iron in piglet;Increased litter sizes, result in lower iron stores at birth for the individual piglet and with the increased litter sizes, the already low levels of iron in the sow's milk are diminished to even lower levels. The fast growers are increasingly at risk of developing iron deficiency, as they face an increased risk of depletion of available iron stores due to their accelerated growth rates.The fast growers are often on an all-milk diet which offers a good source of all nutrients required by the piglet, except for iron. Weight gain on an all-milk diet is, therefore, associated with an increased risk of developing iron deficiency, which could eventually lead to iron deficiency anaemia. story credit; pig progress.

HOW TO START RAISING SNAILS FOR PROFIT.

Snail farming also referred to as heliculture is a lucrative business with high export potential.Snails are small,hardy and easy to manage.They can be raised on small or large scale using various means of housing.The snail business is easy to set up, with simple management. Snail farming is not capital intensive and the feed are readily available and cheap. Snails are not a nuisance to the environment because there is no noise from the pens, and effluents are odorless. 

 The snail is divided into 3 parts; the shell, muscular foot and the visceral mass. The shell is the most visible part which makes up 30-40% of the whole body.The shell is a means of identifying various species, and it has ornamental values.The shell increases with body size,thus its also a means of determining the age of the snails. The muscular part also referred to as foot is the edible part, and makes up 45% of the body weight.Its also the means by which the snails move. The visceral mass houses the internal organs and the reproductive organs. The snails are hermaphrodites, but they still require another snail to lay eggs. 

 Snails can be housed in various enclosures depending on size of stock; old tyres with wire netting,drums,wooden cages, cemented high/low fenced pens or natural gardens .The housing must be intact with no openings for rodents,ants and mosquitoes.The housing must provide shade,to prevent heating up the snails resulting in death. Snails feed on greens,tubers and fruits. Snails can feed on leaves of pawpaw,cassava,fruits of mango,banana,orange.They can also be fed well ground broiler ration,chick mash or layer ration.

The feed must be balanced with adequate components of carbohydrate,fish meal and calcium supplements. Water is very important in snail diet and it must be readily available. The housing of the snail must be covered with loamy soil which must be kept moist to allow the snails to burrow and lay eggs.

The snails/ hatchlings that are to be the foundation stock must be carefully chosen, they should be of good weight (300-350g),with no cracks on shell and no nodules.The snails must be well stocked to prevent cannibalism,death and poor growth. 

 A stocking density of the snails should be 40-50 hatchlings/m2, 30- 40 growers/m2 and 12-15 adults/m2. The sexual maturity of the snail is 5-6 months, upon maturity they lay eggs in presence of other snails and the eggs are buried deep in the sand to protect them. The snails a clutch of 80-100 eggs .Snails can lay up to 300 eggs in a year.

The incubation period is about 18-30 days and the hatchlings come out of soil a day after hatching.If the soil is hard,the hatchlings will not be able to come out,hence wetting of the soil is important.

 HEALTH BENEFITS OF SNAILS. 1) It has low fat and cholesterol content. 2)It is rich in iron,thus recommended for anemic patients. 3)Its a good source of protein. 4)The meat is juicy and tender suitable for young and old.
