The gestation period and parturition days were accurately predicted by measuring progesterone concentration in the plasma from 40 pregnant companion bitches. The mean length of the estrous cycle based on plasma progesterone concentrations were 8.14 ± 1.39 (Mean ± SD) days for proestrus, 9.19 ± 2.01 days for estrus, and 55.38 ± 1.96 days for diestrus phase, respectively. The gestation length from each based on the days was 65.61 ± 2.47 days from the first day of estrus after the first vaginal discharge, 63.21 ± 0.99 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54.51 ± 3.51 days from the first day of diestrus, respectively. Therefore, the parturition day was estimated 65 days from the first day of estrus after the first vaginal discharge, 63 days from the day when plasma progesterone concentrations increase above 4.0 ng/ml, and 54 days from the first day of diestrus, respectively.

Sixteen holstein heifers were employed to study the effect of thermal stress on rectal temperature and mineral status of heifers around parturition during hot and cool weather. During the hot weather, rectal temperatures of the heifers measured at 08:30 and 15:30 h from 7 d prepartum to parturition were higher than those during the cool weather. Blood hematocrit and hemoglobin were not significantly different between the hot and cool weather, but at 2 and 1 wk prepartum, those during the hot weather were higher. Plasma Ca, inorganic P and Fe of the heifers during the hot weather were higher than those during the cool weather, but plasma Mg and Zn and serum alkaline phosphatase during the hot weather were lower. Colostral protein and Mg of heifers at parturition during the hot weather were lower than those during the cool weather, but colostral Ca, P, Fe and Zn were not affected by the weather.

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.

Purpose : This study was conducted to investigate the effect of pregnancy and parity on bone marrow density using Dual Energy X-ray Absorptiometry (DXA) after parturition Methods : The observation cases who was over 20 and under 35 years old just after childbirth were admitted twice to woosuk university hospital from Aug 2000 to July 2005. During the first admission period, we measured the bone marrow density(BMD) using DXA in 13th day, and when the patient came to the hospital just after childbirth again, we followed up the BMD in 13th day. The evaluation index of this report was comparison of the T-score which was about the lumbar spine(L1-L4) BMD and femur neck BMD. Results : The continuous parturition was increased the lumbar spine BMD(P<<0.05), and decreased the femur neck BMD but it had no meaning. In the cases of the parturition interval under 24 months regarded as siblings born within a year of each other, the analysis results of BMD showed increase in lumbar spine BMD. In the cases of the parturition interval over 24 months, there was increased in lumbar BMD, and decreased in femur neck BMD. To the analysis of the weight variation, the increased BMI group has a significant increase in lumbar spine BMD, and the decreased BMI group also increase in lumbar spine BMD but there was no meaning about that. Conclusion : The continuous parturition was increased the lumbar spine BMD.

This study was carried out to investigate the Preventive and treatment effects of mixed compound of vitamin E and selenium, and ursodeoxycholic acid on the pre-parturient and post-parturient fatty liver of high. yielding dairy cows. Thirty pregnant dairy cows(2 weeks preparturition) were divided into clinical(13cows) and subclinical(17 cows) groups based upon blood chemical values, blood serum protein levels and clinical symptoms. The clinical group was subdivided into treated clinical group(6 cows) and non-treated clinical group(7 cows). The cows(treated clinical group) with fatty liver diagnosed before parturition were dosed with mixed compound of vitamin I(1head) and selenium(10mg/head) intramuscularly once before and after parturition, respectively. These cows(treated clinical group) were also given ursodeoxycholic acid(50g/head) intramuscularly 3 times before parturition. The cows(treated clinical group) with fatty liver diagnosed after parturition were also given the same compounds as dosed to the above cows at same dose rate once or 3 times, respectively after parturition. Blood samples were collected from the cows on 4th, 7th and 2nd day of preparturition and on 1st, 7th, 14th and 20th day of postparturition. Blood chemical values(non-esterified fatty acid : NEFA) concentration, serum aspartate aminotransferase activity, serum ${\gamma}$-glutamyl transpeptidase activity, bilirubin concentration, glucose level) were checked and clinical symptoms of the cows were also observed. 1. The cows in non-treated clinical group showed severe depression, anorexia and diarrhea from prepartum period, and retained palcenta, endometritis, ketosis, abomasal displacement and mastitis after parturition. Cows in treated clinical group showed moderate depression, anorexia, diarrhea during preparturient period, but they were relieved within a week from parturition. Cows in subclinical group showed mild depression, anorexia and diarrhea after parturition, but these symptoms were not observed in prepartum period. 2. NEFA concentration, serum aspartate aminotransferase activity, serum ${\gamma}$-glutamyl transpeptidase activity and bilirubin concentration observed In the cows of treated clinical group were significantly lower than those of the cows non-treated clinical group. The blood glucose concentration of the cows in treated clinical group were higher than those of the cows in non-treated clinical group. These results indicate that the preparturient and postparturient fatty liver of high-yielding dairy cows could be reduced by dosing the animals with appropriate amounts of mixed compound of vitamin I and selenium, and ursodeoxycholic acid at proper times of the preparturition and postparturition of the dairy cows.

Objective: Pregnant Nelore heifers (n = 417) were used to evaluate the effects of supplementation with monensin-molasses multinutrient block (B) during pre and/or postpartum on reproductive and progeny performance. Methods: Heifers were allocated in four treatments: i) CC: heifers received control supplement (C) in loose meal form (0.06% of body weight [BW] offered daily before and after parturition; n = 108); ii) CB: received C before parturition and B (0.07% of BW offered weekly after parturition; n = 117); iii) BC: received B before and C after parturition (n = 103) and iv) BB: received B before and after parturition (n = 89). During pre and postpartum periods, concentration of metabolites/hormones and cow/calf performance was evaluated over time. Cows were synchronized twice for fixed timed artificial insemination (FTAI) using an estradiol/progesterone-based protocol. Data was analyzed by orthogonal contrasts (C). Results: B increased pregnancy at first FTAI (p = 0.04) and overall pregnancy rate (C1: CC vs BB+BC+CB; p = 0.05). Supplemented cows had greater body condition score (BCS) only at parturition (D0; p = 0.04) and at D40 (p = 0.02). B increased BW (p = 0.03), glucose concentrations (p = 0.01) and subcutaneous fat thickness (p = 0.03) only at D40. Concentrations of insulin were higher in supplemented cows (p = 0.008). Calves born by cows supplemented before and after parturition (C2: BB vs BC+CB) were heavier at 80 (p<0.001), 120 (p<0.001), 170 (p = 0.002) and 210 (p = 0.02) days old. Conclusion: Regardless of period of treatment, block supplementation increased pregnancy at first FTAI and overall pregnancy rate. Additionality, block supplementation during both pre and postpartum periods improved progeny weight until weaning. Block supplementation can be a tool to optimize fertility and calf performance in Nelore primiparous cows.
