Resumo: | Two research was conducted to evaluate and to classify the occurrence of the preweaning losses (based on the postmortem findings) of piglets in an intense swine production system, at the west of São Paulo State during the year 2000. Among total piglets born alive. 7.19 % died during the first 24 suckling days, but most of them (5.63 %) died on the 1st week of life all over the year. The most important causes of losses were overlaying (2.61 %), weakness (1.45 %), diarrhea syndrome (1.10 %), and genetic defects (0.56 %), occurring mainly on the 1st week of life. Stillbirth rate, in relation to total born, was 5.96 %. Evidences indicated higher number of overlaying during the hottest months of the year, caused probably by the longer staying out of the piglet's pen. It was suggested some control measures to reduce the piglets mortality in order to maximize the productive efficiency of the system. |

Foi verificado que 7,19 % do total de nascidos vivos morreram durante os 24 dias de aleitamento, concentrando a maioria das mortes na 1ª semana de vida, cerca 5,63 %, e independentemente dos meses do ano. As causas mais freqüentes de mortalidade, em relação ao total de nascidos, foram o esmagamento (2,61 %), debilitação (1,45 %), síndrome diarréica (1,10 %) e anomalia genética (0,56%). A distribuição das mortes nos dias após o nascimento variou de maneira similar ao descrito anteriormente, maiores perdas nos primeiros dias de vida devido, principalmente, ao esmagamento, debilitação, síndrome diarréica e anomalia genético. A taxa de natimortos, em relação ao total de nascidos, foi de 5,96 %. Notou-se, ainda, uma tendência de mortalidade por esmagamento nos meses mais quentes do ano, devido, provavelmente, a uma maior permanência dos leitões fora do escamoteador. Medidas de controle direcionadas aos primeiros dias de vida dos leitões devem ser implantadas, a fim de aumentar a eficiência produtiva do SIPS.Universidade de São Paulo.
