Improving productivity in swine industry requires an increase in the number and weight of piglets born alive per sow, the best performance of the mother and the increase in the number of piglets at weaning. The objective of this research was to evaluate the effect of sow diets based on sorghum and soybeans fortified with organic zinc, during the last third of gestation. Eighteen sows were used in the commercial breed ing Yorkshire, Hampshire, Duroc and Landrace second and third birth, randomly distributed into three groups of six animals. In the last third of gestation, Availa ® zinc Zinpro Zinc 100 per 100 kg of food. The treat ments were control without addition of zinc and low dose (18.2) and high dose (36.3) g of zinc supplement. Diets were isoproteic (13.8% CP) and isocaloric (3.607 Mcal Em/kg MS y 0.66% Lis). We recorded the number and weight of piglets at birth and litter weight, this prac tice was repeated at weaning. The data were analyzed in a completely randomized design with equal number of repetitions. The number and weight of piglets at birth and at weaning was not affected by dietary zinc supplementation (p≥0.05), while litter weight at weaning showed significant differences (p≤0.038). The largest litter weight at weaning (66.02 kg) was obtained with the low dose of the supplement. Weight gain per piglet and mortality were not affected by the addition of zinc. However, a higher number of piglets at birth and at weaning were ob served, and better birth weight in females supplemented with low dose of zinc as well as in the litter weight at weaning. We conclude that the production of the females belly increases with supplementing the diet with 18.2 g of zinc supplement per 100 kg of food.
