Production and economic viability of feedlot beef cattle categories

This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piaui State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 [+ or -] 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an bod...

Zusammenfassung:This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piaui State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 [+ or -] 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an body weight of 296.1 [+ or -] 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.sup.-1]; kg [kg.sup.-1] BW), diet cost (R$ [kg.sup.-1] of diet), cost of kg produced (R$ [kg.sup.-1] produced), and average price of the kg of meat for finishing (R$). The CC consumed more sorghum silage and concentrate than B (p < 0.05).There was a difference between the categories (p < 0.05) for gross revenue, balance, opportunity cost, and net revenue per animal, with higher values found for the steer category. The animal category did not affect the profitability of the system, although the bulls provided lower revenues than cull cows. Keywords: performance, production systems, rate of return. Objetivou-se avaliar a producao e a viabilidade economica de bovinos de corte confinados no bioma Cerrado do estado do Piaui, Brasil. Cento e cinquenta bovinos -50 novilhos nao castrados (NNC) com peso corporal de 283,0 [+ or -] 20,82 kg, aos 30 meses de idade; e100 vacas de descarte (VD) com peso corporal de 296,1 [+ or -] 17,80 kg, aos 100 meses de idade--foram utilizados em delineamento inteiramente casualizado. Os indicadores de desempenho animal para a avaliacao da viabilidade economica foram idade inicial (meses), idade de abate (meses), peso corporal inicial (kg), peso corporal final (kg), ingestao diaria de alimento (kg [animal.sup.-1]; kg custo de alimentacao-1 (R$ [kg.sup.-1] de dieta), custo por kg produzido (R$ [kg.sup.-1] produzido) e preco medio do kg de carne para acabamento. Essas variaveis foram obtidas a partir da coleta de dados realizada durante o experimento. As VD consumiram mais silagem e concentrado de sorgo do que os NNC (p < 0,05). Houve diferenca entre as categorias (p < 0,05) para a receita bruta, o saldo, o custo de oportunidade e a receita liquida por animal, com maiores valores encontrados para NNC. A categoria de animais nao afetou a rentabilidade do sistema, embora os novilhos tenham fornecido menores receitas do que as vacas de
