The effect of the non-selective treatment of dairy cows with antibiotics (Chronicin foam--Galena, and Masticort PS--Poland) and the effect of teat disinfection (Jodonal A--Lachema) at the last milking in lactation was studied as exerted on the reduction in the occurrence of infection processes in mammary gland after calving. The trials were performed with 180 cows in three groups of 60 animals. At the last milking the mammary secretion of each cow was sampled for bacteriological examination. Two cow groups were treated at the same time. The occurrence of infection processes in the mammary gland in the period after calving can be characterized as follows: a) in the period after calving the control group had an increased proportion of cows with an infection process in their udders (from 58.3% at the end of lactation to 68.3% in the period of 14 days following calving); b) in the group treated with Chronicin foam the infection was reduced by 3/5, i. e. from 71.7% of cows infected at the start of drying off to 28.3% with infection process after calving; c) in the group treated with Masticort PS the infection after calving was reduced by 3/4 as compared with the infection at the onset of drying off, i. e. from 80% to 20%. In the control group 20% of the cows recovered spontaneously. The preparation Chronicin foam showed 79.1% therapeutic effectiveness. Therapy with Masticort PS was successful in 81.3% of the animals.(ABSTRACT TRUNCATED AT 250 WORDS)
研究了在泌乳期最后一次挤奶时，给奶牛非选择性地使用抗生素（Chronicin泡沫剂——加莱纳公司生产，以及Masticort PS——波兰生产）的效果，以及进行乳头消毒（Jodonal A——拉赫马公司生产）的效果，观察其对产后乳腺感染发生率降低的影响。试验使用了180头奶牛，分为三组，每组60头。在最后一次挤奶时，采集每头奶牛的乳汁进行细菌学检查。同时对两组奶牛进行处理。产后乳腺感染情况如下：a）产后对照组乳房感染奶牛比例增加（从泌乳期末的58.3%增至产后14天的68.3%）；b）使用Chronicin泡沫剂处理的组感染率降低了五分之三，即从干奶开始时71.7%的感染奶牛降至产后28.3%有感染情况的奶牛；c）使用Masticort PS处理的组产后感染率相比干奶开始时降低了四分之三，即从80%降至20%。对照组中20%的奶牛自然康复。Chronicin泡沫剂的治疗有效率为79.1%。Masticort PS治疗成功率为81.3%。（摘要截断于250字）
