摘要

A cross-sectional survey on the prevalence of diarrhoea in pre-weaning piglets, and on management and feeding systems under farm conditions was carried out in Thua Thien Hue Province. Faecal samples were collected from 63 piglets without, and 90 piglets with diarrhoea to determine the occurrence of Salmonella, Escherichia coli (E. coli) and different E. coli antigens (K88, K99 and 987P). The prevalence of diarrhoea was higher in the rainy season than in the dry season (33% vs 18%) and the results indicated differences in prevalence between areas. Salmonella and E. coli were found to the same extent in faeces from piglets without and with diarrhoea. All E. coli antigens were isolated from piglets without and with diarrhoea. However, the frequency was much higher in piglets suffering from diarrhoea. In piglets with diarrhoea antigen K88 was found in 26% and 20% of the samples, antigen K99 in 37% and 24% of the samples, and antigen 987P in 31% and 32% of the samples collected in the dry and rainy seasons, respectively. Nutrient supply for sows and for piglets was low in comparison with feeding standards, which may be a contributory factor to the high incidence of diarrhoea in piglets. Thus, the nutrition of sows as well as piglets could be important components in the aetiology of the disease and needs to be studied further.
