Effects of HACCP system implementation on reproduction, milk quality, and milk sanitation on dairy farms in Korea

摘要

The objective of this study was to investigate the influence of hazard analysis critical control point (HACCP) system implementation on the reproductive efficiency of dairy cattle, milk quality, and veterinary medicine use in dairy farms across Korea. Data were collected from 50 dairy farms before and after the implementation of the HACCP system. Importantly, somatic cell number and bacterial count in raw milk, and monthly expenses for medicine were lower after HACCP system implementation (p&0.05). However, the breeding interval, use of different classes of antibiotics, milk protein, and milk fat content were not changed by implementing the HACCP system. These results indicated that implementation of the HACCP system on dairy farms may reduce the use of veterinary medicine and improve milk sanitation levels.
