Productive performance of York x Landrace sows in a semi-technified farm

Abstract

The aim of this work was to evaluate the productive performance of sows in a semi-technified farm. Sows were F1 York x Landrace inseminated with Pietrain. For the study, we considered 13 litters of the same age. It was recorded number of piglets born, weight at birth and at weaning, as well as number of piglets weaned. The information was recorded in the Pigchamp© program. When analyzing all the information regarding litter size and litter weight, compared with other studies, the data obtained in this work is good. With all the variables recorded, we observed a high and positive correlation, similar to Murillo et al. (2017) results. The use of these variables as indicators of maternal productivity increases with each sow calving.
