Resumo

The present experiment was carried out to evaluate the economic viability of supplementing boar diets with organic selenium aiming to increase the number of seminal doses of sexually mature boars. Twelve boars were divided into three groups: control group received 0.3 mg kg(-1) Se from sodium selenite (n = 4), inorganic group received 0.5 mg kg(-1) Se from sodium selenite (n = 4), and organic group received 0.5 mg kg(-1) Se from Sel-Plex (TM) (Alltech, Inc., n = 4). The experiment was conducted within 10 weeks and analysis was performed fortnightly. No interaction was observed between treatments and weeks for any of the variables analyzed. Boars fed diet supplemented with 0.5 mg kg-1 of organic selenium exhibited a 23% increase in the seminal doses, which resulted in a 37% reduction in the cost of diet per dose produced by boars in this group compared with boars in the inorganic group. It should be pointed out that the total revenue produced by the organic group was 26% higher than the inorganic group. The feeding of organic Se increases the number of seminal doses and reduces the average cost of the diet, demonstrating to be cost-effective. (AU)
