Twenty-eight pigs (14 boars, 7 barrows and 7 gilts) were allotted in four groups of seven pigs each, at an average age of 10 weeks. Fourteen boars were injected with 10 % calcium chloride solution (0.2 ml/kg body wt/testis). Seven boars were injected at 60-65 kg body wt and seven boars remained were injected at 75-80 kg body wt. From 10 weeks of age to slaughter weight (100 kg), barrows ate more (P0.05) feed than pigs in other treatments. For this period, barrows required more (P0.05) feed per kilogram gain than injected boars and gilts. In this period, boars injected at 75-80 kg body wt were not significant in the rate of gain from gilts and barrows. For carcass quality, injected boars had higher (P0.05) lean percentage and lower (P0.05) fat percentage than gilts and barrows. No statistical difference between treatments occurred in most of carcass quality component for consumer. Although some meat characteristics were significant but the score of the taste panels was very closed
