Abstract:

In order to identify the effect of pseudorabies purification on pig production performance, this paper based on the survey of 63 large-scale pig farms in 9 provinces of China, analyzed the effects of pseudorabies purification on the mortality of pigs, the positive rate of gE, the maternal abortion rate and so on, and compared pig production performance between purification and non-purifucation farms in different scale and different stages of purification. The results showed that the pig production performance was improved by the implementation of vaccine immunization, quarantine diagnosis, elimination of positive animals and culture of healthy animals; Pseudorabies purification had the best effect of improving production performance for the farms with the scale of 16 500 to 84 700 head. The longer the time of pseudorabies purification, the greater the production performance of pigs.

Key words: pseudorabies; purification; production performance
