Utilización de Laurato de Nandrolona como Estimulante de Crecimiento en Lechones - Granporsa San Carlos

Abstract

In GRANPORSA-San Carlos, it was evaluated the effect of the use of the nandrolona's laurato as stimulant of the growth of pigs from the 21 to the 77 old days, using 384 crossbred pigs of both sexes, weaned, Totally at random under a Design of Blocks, in factorial arrangement 2x2 (Without vs With and Female vs Male). The use of nandrolona's laurato, allows a recovery of the weight of pigs with low pesos to the 21 days, achieving the best pesos, earnings of weight, nutritious conversion and cost/kg of gain of weight, without committing the consumptions. The male pigs, ratify their biggest capacity to be developed, to achieve the best pesos, earnings of weight, food conversion and the best cost/kg of gain of weight and under similar consumption conditions. The males with laurato achieved similar conversions to the males without laurato, what allows guaranteeing the recovery of pigs among the 21 to 77 days of age that it presents low pesos to the weaning. The presence of nandrolona's laurato like promoter of the growth, allow the best benefits cost in comparison with those that are reported of pigs without this preservative. To use nandrolona's Laurato like stimulant of the growth for pigs from 21 to 77 days of age, with the purpose of recovering the pesos of animals stragglers. To evaluate the effectiveness of the nandrolona's laurato, in normal pigs in order to improve the genetic potential for gain of weight and yield, with tests in each one of the physiologic stages of the animals for supply. To reply the rehearsal at level of other farms, in order to generalize this behavior and to recommend their use at commercial level.
