Reproductive organs from mature Small East African zebu (SEAZ) heifers and cows slaughtered at the Morogoro abattoir were collected twice a month and evaluated over a period of 12 months. Out of the 402 animals from which reproductive organs were taken, 54% were pregnant, 24% were actively cycling and 22% were non-cycling. Various gross abnormalities were observed in the reproductive organs of about 16% of the cattle, and the major reproductive abnormality in both total and the non-cycling animals was various degrees of fibrous adhesion between the ovary and the infundibulum and mesosalpinx. It is concluded that, contrary to common belief, a majority of the female SEAZ cattle that are slaughtered are fertile.
每月两次收集在莫罗戈罗屠宰场宰杀的成熟东非小瘤牛(SEAZ)小母牛和母牛的生殖器官,并在12个月的时间内进行评估。在采集生殖器官的402头动物中,54% 怀孕,24% 处于活跃发情周期,22% 不发情。在约16% 的牛的生殖器官中观察到各种明显异常,在所有动物和不发情动物中主要的生殖异常是卵巢与漏斗部和输卵管系膜之间不同程度的纤维粘连。得出的结论是,与普遍看法相反,大多数被宰杀的雌性SEAZ牛是可育的。
