Comparative Analysis of Mortality Number Before and After HACCP System Implementation in Different Scales of Swine Farm

Abstract

This study was conducted to compare the mortality number of swine between before and after HACCP implementation on different scales of swine farm. The study was carried out by randomly selected sixty swine farms (twenty small, twenty midium and twenty large scales of farm) located in all around Korea. The results were as follows: In small scale swine farm, The mortality number due to respiratory, diarrhea and accidental death tended to be decreased compared to before HACCP implementation. In the case medium scale farm, the mortality number due to diarrhea significantly decreased after HACCP compared to before HACCP. Also, in both medium and large scale farms, the number of total mortality number significantly decreased with HACCP implementation. We believe that this effect is considered to be due to the operation of the HACCP prerequisite program. We are expecting that our results might be used for producing safer livestock products by improving livestock products HACCP policy.
