조충호,김덕환,Jo, Choong-Ho,Kim, Duck-Hwan 대한수의학회 1978 大韓獸醫學會誌 Vol.18 No.2
Thirty heads of healthy pregnant and six heads of nonpregnant Holstein Friesian cows were selected for the purpose of serum chemical analysis. The partitions studied include serum total protein and total lipid with gestation periods (2.4.6.8. and 10 Months). The results were summarized as follows: 1. The mean value of serum total protein in 2 months of pregnant group was $7.70{\pm}0.28$ (7.4~8.3) g/100ml and then showed a tendency of decrease with the progress of pregnancy, that of 10 months group was figured $7.32{\pm}0.28$ (6.9~7.8) g/100ml. 2. The mean value of serum total lipids in 2 months of pregnant group was $335.67{\pm}14.69$ (300~386) mg/100ml and then showed a tendency of increase with the progress of pregnancy, that of 10 months group was figured $399.00{\pm}11.48$ (386~443) mg/100ml.
한우(韓牛)의 임신기간(姙娠期間)에 따른 혈청효소(血淸酵素) 활성도(活性度) (GOT, LDH 및 ALP) 의 변화(變化)
조충호,Jo, Chung-Ho 대한수의학회 1982 大韓獸醫學會誌 Vol.22 No.1
Serum glutamic oxaloacetic transaminase (GOT), latic dehydrgenase (LDH), and alkaline phosphatase (ALP) activities were determined in 5 Korean native cattle to obtain the base line of blood enzyme activities in relation to the stage of gestation. Serum GOT activities showed an increasing tendency with the course of gestation period, serum LDH levels were within normal range through all the stage of pregnancy, and the slight increase in serum ALP activities was acknowledged at the 2nd and 3rd stage of gestation.
유우(乳牛)의 번식능률(繁殖能率)에 관한 연구(硏究) 1. 분만후(分娩後) 수태시(受胎時)까지의 소요일수(所要日數)

The survey was carried out to investigate the average number of days from parturition to conception to 349 calving cases out of Holstein cows in total 154 heads observed. The results were as follows: 1. The average number of days from parturition to conception was $97.41{\pm}8.22$ and it's similar during the period from primipara to 4th calving order, and irregular during on and after 5th. 2. The average number of days from parturition to conception in calving month was observed all through the year: the prolongation among on April and July, and the brief duration among on January and March. 3. In the cases under 50 and 150 days after delivery, the distribution showed 53.56% and 83.91%, respectively, and it's about 20% between 70 and 90 days after delivery.
한우(韓牛)의 성주기(性週期)에 따른 혈청(血淸) GOT 및 혈청(血淸) ALP 활성도(活性度)의 변동상에 관하여
조충호,Jo, Chung Ho 대한수의학회 1981 大韓獸醫學會誌 Vol.21 No.2
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 (0~1 days), metestrus (2~6 days), diestrus (7~16 days), proestrus (17~20 days). The results were as follows. 1. Serum GOT activities at estrus ranged from 73.5 to 121.5 Ku with a mean of $89.14{\pm}17.16$ Ku, at metestrus 57 to 89 Ku with a mean of $67.01{\pm}10.81$ Ku, at diestrus 54 to 89.5 Ku with a mean of $67.05{\pm}10.05$ Ku and at proestrus 53 to 112 Ku with a mean of $73.00{\pm}20.05$ 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 $8.74{\pm}0.83$ K-Au, at metestrus 6.5 to 9.2 K-Au with a mean of$7.74{\pm}0.76$ K-Au, at diestrus 5.6 to 9.0 K-Au with a mean of $7.67{\pm}1.13$ K-Au, at proestrus 6.2 to 9.3 K-Au with a mean of $7.12{\pm}1.18$ 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/10dl with a mean of $7.25{\pm}0.57/100dl$, at metestrus, 6.37 to 7.9g/100dl with a mean of $7.65{\pm}0.50g/100dl$, fat diestrus, 6.56 to 8.67g/100dl, with a mean of $7.53{\pm}0.55g/100dl$ and at proestrus 5.94 to 7.71g/100dl with a mean of $6.54{\pm}0.65g/dl$. There was not significance among the stages of estrus cycle.

The experiment was carried out to determine the concentrations of total calcium and inorganic phosphorus of thirty rera obtained from pregnant Holitein cows, six sera from normal non-pregnant cows with one month after delivery, six sera from cows with ovarian cyst and six sera from heifer of sixteen months old. The changes of total calcium and inorganic phosphorus were observed on the 2nd, 4th, 6th, 8th, and l0th month of gestation. The results obtained in this work were summarized as follows: 1. The mean values of total serum calcium obtained from the pregnant group were $9.59{\pm}0.34mg/100ml$, from the non-pregnant group $10.23{\pm}0.47mg/100ml$, from the infertility grou $10.37{\pm}0.27mg/100ml$, and from the heifer group $10.07{\pm}0.20mg/ml$. The change of total serum calcium values in the pregnant group revealed the tendency of decrease as gestation progresses and the lowest value appeared on the sixth month. The mean value of total serum calcium in the pregnant group was lower than those of the other groups, but the differences were not statistically significant. 2. The mean values of serum inorganic phosphorus obtained from the pregnant group were $5.82{\pm}0.31mg/100ml$, from the non-pregnant group $5.92{\pm}0.44mg/100ml$, from the infertility group $5.80{\pm}0.49mg/100ml$, and from the heifer group $5.10{\pm}0.32mg/100ml$. The change during pregnancy showed a slight fall and the lowest value appeared on the sixth month. The differences of serum inorganic phosphorus values between the pregnant group and the other adult groups were not significant, but these adult groups showed a significantly higher value than that of heifer group (p<0.05).
