Abstract | This study aimed to evaluate the economic result of the termination of feedlot sheep fed silages with different cultivars of sorghum 'BRS 810' and 'BRS Ponta Negra' (forage); 'BRS 610' (dual purpose character) and 'BRS 655' and 'BRS 800' (character grain). Five lambs without defined breed were used, aged between 5 and 7 months, with average weight of 17.7 [+ or -] 3.7kg. The animals were confined in individual cages for 42 days and slaughtered at an average weight of 26.24kg. A completely randomized design was used with five treatments (silage of different cultivars of sorghum) and seven repetitions. The forage: concentrate ratio was 48:52 (DM basis) for all diets. The average cost of silage was 63.71, 71.01, 78.99, 61.08 and 63.35 R$ [t.sup.-1] for 'BRS 610', 'BRS 655', 'BRS 800', 'BRS 810'and 'BRSPonta Negra', respectively promoting a net earnings of 78.34, 78.98, 77.43, 82.23 and 80.57 R$ carcass-1. The silage production using the 'BRS 810' with forage purpose has lower production costs and higher net income for carcass. Furthermore higher dry matter production per hectare provided increased support of forage cultivated areas capacity, which allowed greater amount of confined animals. |
