Description
Summary:This study was conducted to evaluate the technical and economic performance and determine profitability through the economic sensitivity analysis of immune (IM) and male pigs surgically castrated (SC). Two experiments were conducted in a completely randomized design, consisting of two treatments (IM and SC) with eight replicates of 10 animals each, totaling 160 pigs per experiment. It was found that IM pigs have lower feed intake and feed conversion during the growth phases in relation to SC. In the finishing phases, IM have better weight gain, feed conversion, carcass yield and lean meat percentage in relation to SC. The use of IM increases the profitability in pig production. The analysis of profitability differential between IM and SC should consider all stages of creation, since the differential performance of not castrated pigs during growth influences economic results of production. Key words: sensitivity analysis, carcass, immunocastration, profitability. Realizou-se este estudo com o objetivo de avaliar o desempenho tecnico-economico e determinar a lucratividade, por meio da analise de sensibilidade economica, de suinos machos imuno (IM) e cirurgicamente castrados (MC). Foram realizados dois experimentos, em delineamento inteiramente casualizado, composto por dois tratamentos (IM e MC), com oito repeticoes de 10 animais cada, totalizando 160 suinos por experimento. Verificou-se que suinos UM apresentam menor consumo de racao e melhor conversao alimentar nas fases de crescimento em relacao aos MC. Na fase de terminacao, suinos IM apresentam melhor ganho de peso, conversao alimentar, rendimento de carcaca e porcentagem de carne em relacao aos MC. A utilizacao de IM aumenta a lucratividade na producao de suinos. A analise de lucratividade entre suinos IM e MC deve considerar todas as fases de criacao, uma vez que o desempenho diferencial dos suinos nao castrados na fase de crescimento influencia economicamente os resultados da producao. Palavras-chave: analise de sensibilidade, carcaca, imunocastracao, lucro.
