Twelve calves of the Red Spotted breed and its crossbreds born by first-calvers, kept in a large-capacity stable of a dairy farm, were subject to the study of the ontogenetic development of the values of the blood picture from birth up to the 10th day of age. The erythrocyte and leucocyte count, the packed cell volume and the relative and absolute number of neutrophils reached the significantly highest levels in calves before drinking the colostrum. The amount of haemoglobin, MCV and MCHC reached the highest values on the first day after birth. The values of the red blood picture decreased in the first week of life and reached the minimum on the tenth day. The leucocyte count decreased during the first to second day after birth, the decrease being due to a drop of the absolute number of neutrophils, and on the tenth day the leucocyte count returned to its initial value. Neutrophils prevailed in the peripheral blood of new-born calves whereas lymphocytes prevailed in the peripheral blood from the fourth day of life on. The amount of cosinophiles in the peripheral blood of the calves was about 0.5% up to the fourth day; on the seventh day it exceeded 1%. The relative number of monocytes was at its minimum level just after birth and showed a significant increase during the second to fourth day.
选取了12头由初产母牛所生的红斑品种及其杂交品种的犊牛，它们饲养在一家奶牛场的大容量牛舍中，用于研究从出生到10日龄期间血常规指标的个体发育情况。在犊牛饮用初乳前，红细胞和白细胞计数、红细胞压积以及中性粒细胞的相对和绝对数量达到显著最高水平。血红蛋白量、平均红细胞体积和平均红细胞血红蛋白浓度在出生后第一天达到最高值。红细胞指标值在出生后的第一周下降，并在第十天达到最低值。白细胞计数在出生后的第一至第二天下降，下降原因是中性粒细胞的绝对数量减少，到第十天时白细胞计数恢复到初始值。新生犊牛外周血中以中性粒细胞为主，而从出生后第四天起外周血中以淋巴细胞为主。犊牛外周血中的嗜酸性粒细胞数量在第四天前约为0.5%；在第七天时超过1%。单核细胞的相对数量在出生后刚处于最低水平，并在第二至第四天显著增加。
