Efficiency mustelina during mastitis in lactating cows

Abstract

The aim of the study is to study the therapeutic efficacy of the drug masti-vin in serous catarrhal mastitis of cows. The composition of the preparation includes rifampicin, gentamicin and methyluracil. Experimental studies were performed in ZAO them. Mi-churin of the Smolensk region of the Smolensk region and in the laboratory of the FSBI of the Smolensk Research Institute of Agriculture during the winter stall period on lactating cows. In the experiment was experimental (n = 40) and control (n = 40) groups of cows. The experimental group was intrastitally injected with mastivin. In the control group used amoxicillin-ling, long used in the economy. Diagnosis of mastitis was carried out according to the “Manual on the diagnosis, therapy and prevention of mastitis in cows” (2007) using masterst. The species composition of the secretion microflora and the antimicrobial activity of the preparations mastavine and amoxicillin were determined using the disc method. During the experiment, it was proved that the drug mastavin has a high activity for the microflora isolated from the secret of the udder of patients with mastitis of cows, so in relation to Str. agalactiae growth zone was 24mm, with respect to Staph. 27mm aureus, Escherichia coli 32mm. The drug amoxicillin used in this economy also had animicrobial activity to the selected microflora. However, apparently due to the regular use of it, there has been a tendency to reduce sensitivity, so already with respect to Str. agalactiae growth zone was 18mm, Staph. aureus 20mm, and Escherichia coli 21mm. The experimental studies carried out testify to the high therapeutic efficacy of the new drug mastavine in comparison with amoxicillin used for a long time in the economy.
