Abstract

Objective of this study was to determine the effect of follicle stimulating hormone; FSH on an efficacy of piglets’ production of large white – landrace crossbred gilts. Twenty crossbred gilts, twenty-eight weeks old, with average weights of 120±20 kilogram, were divided in to 4 groups. Each group (n=5) was injected with Folltropin-V®, at rates of 0, 50, 100 and 200 mg, respectively. This study was done, based on a completely randomized design (CRD). It was found that there were effects from Folltropin-V^® on total number of pig born and birth weight of gilts. However it had no effect on conception rate and survival rate of piglets, after weaning. The hormone treated gilts at doses of 200 milligrams gave highest piglet yield per litter, significantly higher than other hormonal regimes (p≤ 0.05). However, their newborn had lowest body weight, similarly to the treated gilts at a doses of 100 milligrams; (p>0.05) but significantly lower than those treated with Folltropin-V® at a doses of 0 and 50 milligrams (p≤ 0.05).
