초록
This study was designed to assess effect of MUN concentration on reproduction performance and monitoring of feeding and fertility management in commercial dairy herd. The mean of milk yield is 26.48±8.38㎏ per day, milk fat 3.80±0.58%, protein 3.13±0.3% MUN 16.68±5.87㎎/㎖ and somatic cell 392,000±77,060㎖. Milk yield has been shown that negative correlation with fat, protein and somatic cell(P〈0.01). The finding of this study was significant relationship between non-pregnant days and MUN concentration.
