Abstract

The somatic cell count (SCC) was determined in 28 milk sheep with normal udder health using the California Mastitis Test (CMT) and a fluoro-opto-electronic cell counter (Partec Counter). The examinations were made at two week intervals throughout the lactation period. 92% of the premilking samples had a negative CMT reaction and in 0.5% of the samples the reaction was distinctly positive. In 95% of the premilking samples the SCC showed less than 200,000/ml and in 95% of the individual total milkings it was less than 350,000/ml. Elevated SCC were common towards the end of lactation when milk yield was low.

摘要

使用加利福尼亚乳房炎检测法（CMT）和荧光光电细胞计数器（帕泰克计数器）对28只乳房健康正常的奶羊测定体细胞计数（SCC）。在整个泌乳期每隔两周进行一次检测。92%的挤奶前样本CMT反应为阴性，0.5%的样本反应明显呈阳性。95%的挤奶前样本SCC低于200,000/ml，95%的单次总挤奶量中SCC低于350,000/ml。泌乳期末产奶量低时，SCC升高的情况很常见。
