Study of the mortality rate in pre-fattening pigs

The focus of this experimental work was the long-term analysis of the mortality of pigs in the pre-fattening category, as well as the determination of the most important etiological and predisposing factors of death. We carried out this research on farm in the east of Slovakia, in the Spiš region, over a period of three years. Based on our 36-month monitoring of pig mortality, we found that pre-fattening mortality was on a downward trend with mortality rates of 2.79%, 2.72% and 2.71% in consecutive years. There is also a certain seasonal impact on mortality in pre-fattening, because we found a higher incidence of deaths especially in the cold spring, autumn and winter months. Diseases such as respiratory and diarrheal diseases were among the most important etiological and predisposing factors of mortality in the observed farm.
