Devido ao aumento da ovinocultura nos últimos anos, práticas de manejo precisaram ser aprimoradas para suportar o maior número de animais por área, porém é preciso observar cada atividade produtiva individualmente. Assim, objetivou-se analisar a viabilidade econômica e os componentes que exercem maior influência sobre o custo da terminação de ovinos em pasto de capim-tifton 85. O estudo foi realizado em duas etapas. Na etapa 1, realizou-se experimento visando avaliar a produção do capim-tifton 85 irrigado com efluente de tanque de piscicultura e fertilizado com NPK nos níveis de zero, 33, 67, 100, e 150% do recomendado pelo manual de análise de solo de Pernambuco-PE. Na etapa 2, consistiu do estudo da viabilidade econômica da terminação de ovinos simulada para áreas de 10 ha com base nos resultados da produção alcançados na etapa 1. Realizaram-se cálculos de custo fixo, variável, operacional, total, margem bruta e líquida além da lucratividade e rentabilidade. Os maiores custos foram com a terra e à compra de borregos. A margem bruta foi positiva para todos os sistemas, já a margem líquida, a lucratividade e a rentabilidade, constatou-se que no sistema que não foi fertilizado apresentou valores negativos (R$ -70.832,56, -19,14% e -16,06%) inviabilizando a atividade. O sistema com maior fertilização do solo (150% do recomendado de NPK) foi o mais lucrativo e economicamente viável, pois apresentou valores positivos para os índices de lucratividade (17,39%) e rentabilidade (21,06%), superior aos demais, já o sistema que não utiliza fertilização é inviável, pois apresenta lucratividade e rentabilidade negativa.

Due to increase in sheep production in recent years, handling practices needed to be improved to support the largest number of animals per area, However is necessary to observe each productive activity individually. So, this study aimed to analyze the economic viability and the components that have more influence on the cost of sheep termination in pasture of Tifton 85. The study was conducted in two stages. In stage 1, was held experiments to evaluate the production of irrigated Tifton 85 with fish pond effluent and fertilized with NPK in zero levels; 33, 67, 100 and 150% of the recommended by soil analysis manual of Pernambuco-PE. In stage 2, of the study of the economic viability of the ovine simulated termination for a 10 ha area based on the results of production achieved in stage 1. Was carried fixed cost calculations, variable, operational, total, gross margin and net, beyond of lucrativity and profitability. The higher costs were with the land and the purchase of lambs. The gross margin was positive for all systems, since the net margin, the lucrativity and profitability, it was found that the system was not fertilized with negative values (R $ -70,832.56, -19.14% and -16.06%) impeding the activity. The system with greater soil fertilization (NPK 150% recommended) was the most lucrative and economically viable, because presented positive values for the lucrativity indices (17.39%) and profitability (21.06%), superior to the others already the system does not use fertilization is unfeasible because it presents lucrativity and negative profitability.
Keywords: Cynodon spp., fertilization, lucrativity, viability of the production.
