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.
