Abstract

ABSTRACT: In recent years there has been great interest in oligoelements and in particular in selenium. This mineral is a cofactor of the glutathione peroxidase, enzyme responsible for the destruction of hydrogen peroxide formed in the oxidative reactions in the metabolic process. Selenium is a mineral that can be deposited at different levels in the tissues depending on the amount and source of selenium added in animal diets. In many parts of the world consumption of this mineral is insufficient and does not meet the requirement people have, This is when animal products such as pork meat enriched with selenium play an important role. This research evaluated the  effect of supplemented organic selenium in growing-finishing pig diets on the zootechnical parameters and their deposition in muscle. The experiment was carried
out in the pig farming section of the Montelindo farm at Universidad de Caldas. Eighteen pigs with an average weight of 70 kg were used. They were divided into two treatments with three repetitions and three pigs per replicate. A 0.30 ppm diet of corn and soybean meal varying only the source of selenium was provided; for treatment 1; a 0.30 ppm organic selenium diet was added to treatment 2. Food was offered ad-libitum. Organic selenium proved to be more effective to deposit in muscle (Longissimus dorsi) and significantly improved feed intake, weight gain and carcass weight.
