Improvement of reproductive performance by the application of reproductive herd health program in high yielding dairy herds



Improvement of reproductive performance by the application of reproductive herd health program in high yielding dairy herds



Korean Journal of Veterinary Research 44(2): 293-301



We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group).
