Changes in s - GOT and s - ALP Activities in the Korean Native Cows within Estrus Cycle

Abstract
Changes in serum glutamic oxaloacetic transaminase (s-GOT) activities, serum alkaline phosphatase activities and serum total protein amounts were investigated on seven Korean native cows having normal estrus cycle of 18-24 days after normal parturition, dividing estrus cycle into estrus (0¡­1days), metestrus (2¡­6 days), diestrus (7¡­16 days), proestrus (17¡­20 days). The results were as follows.
1. Serum GOT activities at estrus runged from 73.5 to 121.5 Ku with a mean of 89.14¡¾l7.16 Ku, at metestrus 57 to 89 Ku with a mean of 67.01¡¾10.81 Ku, at diestrus 54 to 89.5 Ku with a mean of 67.05¡¾10.05 Ku and at proestrus 53 to 112 Ku with a mean of 73.00¡¾20.05 Ku. The activities were significantly increased at the estrus comparing with other stages (P <0.01) .
2. Serum ALP activities at estrus ranged from 8.0 to 10.4 K-Au with a mean of 8.74¡¾0.83 K-Au, at metestrus 6.5 to 9.2 K-Au with a mean of 7.74¡¾0.76 K-Au, at diestrus 5.6 to 9.0 K-Au with a mean of 7.67¡¾1.13 K-Au, at proestrus 6.2 to 9.3 K-Au with a mean of 7.12¡¾1.18 K-Au. The significance was not recognized among the stages of estrus cycle.
3. Serum total protein amounts at estrus ranged from 6.45 to 8.0g/100§£ with a mean of 7.25¡¾0.57g/100§£, at metestrus, 6.37 to 7.9g/100§£ with a mean of 7.65¡¾0.50g/100§£, fat diestrus, 7.56 to 8.67g/100§£, with a mean of 7.53¡¾0.55g/100§£ and at proestrus 5.94 to 7.71g/100§£ with a mean of 6.54¡¾0.65g/§£. There was not significance among the stages of estrus cycle.
