The effect of induction of parturitions in the 1-2 weeks of pregnancy was tested as exerted on the health of calves and on some biochemical and hematological indicators. The observations concerned 26 cows, out of which 14 cows (experimental group) were applied intramuscularly 500 micrograms of synthetic analog of prostaglandin F2 of alpha- cloprostenol. The other 12 cows were a control group. These indicators were determined in the blood of calves before colostrum intake, in 24 h, 5 and 15 days from the intake of the first colostrum ration: acid-base balance, hematocrit and leucocyte counts, in the blood plasma it was concentrations of glucose, urea, Na, K, Ca, inorganic P, vitamin A and E levels and AST and GMT activities. The same range of examinations was performed in the blood and/or in the blood plasma of cows, in addition to urea screening. Blood and urea samples were taken a month before and a month after parturition. No deviations from the normal state were found by the examination of highly-pregnant cows. Afterbirth retention was found in 87% cows of the experimental group after parturition, while it was only 9.8% in the control group. All the calves in the experiment had good vitality, very good health in the course of 15-day observation. There were not any significant differences in the birth weight and weight gains of the calves of experimental and control groups.(ABSTRACT TRUNCATED AT 250 WORDS)
对妊娠1 - 2周进行引产对犊牛健康以及一些生化和血液学指标的影响进行了测试。观察对象为26头奶牛，其中14头奶牛（实验组）肌肉注射500微克前列腺素F2的合成类似物氯前列醇。另外12头奶牛为对照组。在犊牛摄入初乳前、摄入初乳后24小时、5天和15天，测定这些指标：酸碱平衡、血细胞比容和白细胞计数，在血浆中测定葡萄糖、尿素、钠、钾、钙、无机磷、维生素A和E水平以及AST和GMT活性。除尿素筛查外，还对奶牛的血液和/或血浆进行了相同范围的检查。在分娩前一个月和分娩后一个月采集血液和尿素样本。对妊娠后期的奶牛检查未发现偏离正常状态的情况。实验组87%的奶牛产后出现胎衣不下，而对照组仅为9.8%。实验中的所有犊牛活力良好，在15天的观察期内健康状况极佳。实验组和对照组犊牛的出生体重和体重增加没有显著差异。（摘要截选至250字）
