Evaluación productiva y análisis microeconómico del maní forrajero perenne (Arachis pintoi) en un sistema de levante-ceba de porcinos en confinamiento Productive evaluation and micro-economic analysis of perennial Arachis pintoi for raising and fattening pigs in confinement
Abstract
Con el fin de evaluar la respuesta productiva y microeconómica del maní forrajero (Arachis pintoi) como reemplazo parcial de la proteína cruda en cerdos en las etapas de levante y ceba, se realizó una investigación con 12 hembras, divididas al azar en cuatro tratamientos: T1. Grupo testigo, alimentado con concentrado comercial; T2, T3 y T4, con 10, 20 y 30%, respectivamente, de reemplazo de la proteína de la dieta a partir de maní. Las variables evaluadas fueron consumo de alimento, peso corporal, ganancia diaria de peso, grasa dorsal, conversión alimenticia y la relación valor del alimento/valor de la ganancia de peso. No se encontró diferencia estadística significativa entre los diferentes tratamientos para todas las variables evaluadas, excepto para el promedio de la ganancia diaria de peso durante la etapa de levante (p To make an evaluation of the productive and micro-economic aspects of Arachis pintoi as a partial replacement of crude protein in pigs a group of 12 female pigs & was studied under four randomly asigned subgroups: T1: Witness group, was fed commercial concentrate; in subgroups T2, T3 and T4, 10, 20 and 30%, respectively, of their dietary protein was replaced by Arachis pintoi. The evaluated variables were intake, corporal weight, daily gain of weight, back fat, nutritional conversion and the relation between the feed cost and the value of the weight gained. The results indicate that there were no significant statistical differences between the different treatments for any of the evaluated variables, except for the average daily weight gained during the raising stage (p <0.01), with the greater values for T1 (1.01 kg/animal/day) and the lowest for T4 (0.78 kg/animal/day). The microeconomic analysis shows that the smaller cost associated to the production of 1 kg of pig was obtained for T3, 45% with respect to T1. The behavior of the gross partial gain was superior for T3, 46% higher than T1. This was therefore the treatment presenting the better conversion.
