A total of 80 gilts were selected and divided into two experimental groups of 40 animals each. Group I, grouped gilts with weights of 118 to 124 kg. And group II, those weighing more than 130 kg. The weight of incorporation of the gilts, as well as the litter size and the birth weight, at the weaning and average daily gain of the piglets, were controlled through simple ANOVA; in addition to relating the weight of incorporation of the gilts with the litter size, birth weight and weaning by linear regression, using the program Stagraphics plus 5.1. The results showed that there is a strong and positive relationship between the weight of incorporation of the gilts and the productive indicators of the piglets, which were always higher in the incorporated gilts weighing more than 130 kg. It was shown that more live piglets are born from incorporated gilts weighing more than 130 kg and that mortality is higher when the incorporation weights are lower than this. It was verified that in the incorporated gilts with less than 130 kg of live weight, 50575.00 Cuban pesos loosen benefits for fewer live born piglets.
