Abstract
This study was conducted to investigate effects of maternal genetic potential and parity with pre- and postpartum periods on body weights, body condition score (BCS) and blood metabolites in relation to physiological stress and nutritional metabolism in Hanwoo cows. Also, this study was designed to develop effective husbandry technique for Hanwoo cows concerning of pre- and postpartum periods, and to get basic data for it. Forty five cows were allocated into two groups, 24 cows with high maternal genetic potentials and 21 cows with low maternal genetic potentials. The average parity of experimental cows with high and low maternal genetic potentials were 2.83±1.63 and 3.00±1.77, respectively. The growth performances such as body weights, average daily gain (ADG) and BCS were not different between two groups regardless of maternal genetic potential. However, pre- and postpartum periods had effects on the growth performances (p<0.05). Parity had no effects on ADG and BCS (p>0.05), but effect on body weight of cows (p<0.05). The metabolites of physiological stress such as neutrophil, hematocrit and cortisol, and nutritional metabolites such as albumin, blood urea nitrogen (BUN), triglyceride, and non-esterified fatty acid (NEFA) concentrations in blood of cows were affected by pre- and postpartum periods in a large scale, while those were partially affected by maternal genetic potential. However, among the metabolites in blood, only neutrophil and triglylceride concentrations were affected by different parity of cows. Therefore, the present study suggests that nutritional intake and digestion are affected by physiological stress due to the parturition, and it should need to consider different husbandry technique based on the maternal genetic potential, and pre- and postpartum periods of cows.
