The aim of the study was to determine how the spread of contagious agalactia in sheep and goats in the Odesa region depended on the age of the animals and the season.
From January 2016 to December 2018, 1,964 ewes and 1,484 nanny goats of different age groups were studied by ELISA for antibodies to .
The highest incidence of contagious agalactia was registered in one-year-old animals and was 59.7‒83.0%, two-year-old ruminants showed 17.0‒40.3% prevalence, in livestock at the age of 3-4 years no serological evidence of the disease was registered and in ewes and nanny goats older than 5-6 years 1.5-3.6% were infected. The most susceptible were young animals at the age of one-month (11.6‒14.5%). The first peak of the disease was recorded in March‒April (21.0‒26.1%), in the lambing period, which coincided with the beginning of lactation and the suckling period, and the second peak occurred in June-July (28.9‒34.2%), the period of maximum lactation and of manual milking of sheep and goats.
The results of serological investigations indicate the circulation of in small ruminants in the south of Ukraine. To avoid greater dissemination of the pathogen, appropriate measures should be applied and strategies for its control need to be drawn up.
本研究的目的是确定敖德萨地区绵羊和山羊传染性无乳症的传播如何取决于动物的年龄和季节。
2016年1月至2018年12月，采用酶联免疫吸附测定法（ELISA）对1964只不同年龄组的母羊和1484只母山羊进行了抗体检测。
传染性无乳症发病率最高的是一岁的动物，为59.7%‒83.0%，两岁的反刍动物患病率为17.0%‒40.3%，3至4岁的家畜未发现该疾病的血清学证据，5至6岁以上的母羊和母山羊感染率为1.5%‒3.6%。最易感的是一个月龄的幼畜（11.6%‒14.5%）。该病的第一个高峰出现在3月至4月（21.0%‒26.1%），正值产羔期，与泌乳开始和哺乳期相吻合，第二个高峰出现在6月至7月（28.9%‒34.2%），这是绵羊和山羊泌乳量最大以及人工挤奶的时期。
血清学调查结果表明乌克兰南部小型反刍动物中存在[病原体名称未给出]的传播。为避免病原体的进一步传播，应采取适当措施并制定控制策略。
