Abstract
This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piauí State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 ± 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an body weight of 296.1 ± 17.80 kg, at 100 months of age- were used in a completely randomized design. The animal performance indicators for the evaluation of economic viability were initial age (months), slaughter age (months), was initial body weight (kg), final body weight (kg), daily feed intake (kg animal-1; kg kg-1 BW), diet cost (R$ kg-1 of diet), cost of kg produced (R$ kg-1 produced), and average price of the kg of meat for finishing (R$). The CC consumed more sorghum silage and concentrate than B (p < 0.05).There was a difference between the categories (p < 0.05) for gross revenue, balance, opportunity cost, and net revenue per animal, with higher values found for the steer category. The animal category did not affect the profitability of the system, although the bulls provided lower revenues than cull cows.
Highlights
IntroductionIn view of the great competition between crop and livestock and the high demand for land, the feedlot stands out as a good option in beef cattle farming, because when the adequate management techniques are applied and investments are made at the right time, this rearing system becomes economically viable (Silva et al, 2010)

Brazil still has a low percentage of animals finished in feedlot; the feedlot practice is increasingly present in relation to previous years, which is explained by the increased amount of grains in the market, coupled with the increasing food alternatives to make up diets (Leão et al, 2012)
Summary
In view of the great competition between crop and livestock and the high demand for land, the feedlot stands out as a good option in beef cattle farming, because when the adequate management techniques are applied and investments are made at the right time, this rearing system becomes economically viable (Silva et al, 2010). In the Cerrado region, most producers do not have the habit to finish cull cows in feedlot, since they are old, unappreciated animals They are finished on pasture and sold for a low price. The Brazilian literature lacks information on the productive comparison between finishing bulls and cull cows in feedlot associated with their weight gains, acquisition price, among other particular factors of each category. Given these considerations, the present study was realized to evaluate the production and economic viability of bulls and cull cows finished in the feedlot in the Cerrado, Piauí State
