Abstract

The investigation was made in the belonging to Holguin's Porcine Company; with the objective of evaluating the influence of the race and the period of the year in the low of porcine reproductions; for it there were examined the race, the date, and the causes of the low or discard of the sow since the 2013 to 2015. To carry out the mathematical analysis it was used the statistical package of InfoStat version 2008. There was an analysis of variance of simple classification. Where there was a significant difference and it was made Tukey's proof of multiple ranges. The race Yorkshire showed better results in relation to the York – Lan because there were dismissed less sow for the examined causes becoming evident the superiority referent to this aspect. During the rainy season there was a significant increment of discarded reproductions regarding to the dry period in the evaluated causes, affecting the reproductive behaviour of this category.
