Abstract

In the pig industry the mortality of piglets both during the birth process and in the subsequent 3 to 5 weeks is unacceptably high. This review attempts to summarize the major causes of these losses and to suggest means whereby such losses may be minimized in the commercial situation. Stillbirth rate is discussed in relation to various management regimes and it is concluded that anoxia (the primary cause of intra-partum piglet deaths) may be minimized by the provision of careful assistance during the birth process. Pre-weaning mortality is presented as a complex interaction of factors predominant amongst which are overlying by the sow, chilling, starvation and infection. Each of these areas is discussed in detail and recommendations are made to reduce their negative influence on the survival rate of piglets. Finally, the rōle of piglet activity level/vigour is considered in relation to pre-weaning survival rate. Various factors are discussed in relation to piglet vigour and it is concluded that the two major contributors to low activity level/vigour are intra-partum hypoxia and the endocrine status of the sow and piglet at birth. To reduce hypoxia, careful intervention is again suggested. The rôle of endocrine status is yet to be fully established but promising results are presented on the use of oestradiol treatment of piglets at birth to raise activity level and reduce pre-weaning mortality rate.
