Health issues when selecting breeding stock

摘要

Although health has a major influence on productivity, other components such as management, genetics and housing also play a significant part. A comparison of two farrow to finish farms with pigs of different health statuses shows that despite th is resu Its can be similar. Farm A is in an area with few other commercial livestock enterprises, the nearest pig unit is at least 10 kilometres away. There has also been a considerable input to maintain biosecurity. In contrast, Farm B has six other pig farms within a 3km radius, and despite having a high level of biosecurity, has over the years succumbed to the health status in the locality.
