Summary
The aim of our work was the study of injuries in dairy cattle breeding of the Vologda
region. The results of the study show that the recovery of clinical characteristics by
experimental wounds in injured animals of control group occurred on the 14th day, in
animals of the test groups - on the 7th day. The purification of the wound surface from
purulent-necrotic masses in test groups was observed on the 8.1±0.2 day and in the
control group - on the 13.4±0.8 day. The reducing of the inflammatory edema occurred
in test groups on the 9.4 ±0.2 day and in the control group - on the 13,1±0,8 day. By
the beginning of the 7th day the granulation was observed in all groups but its character
was different. In animals of the control group the layer of maturing granulation was
heterogeneous, grains were large, loose and swollen, in the test groups the granulation
was filled with blood, fleshy and fine. The even filling of the wound defect occurred in the
test groups on the 21.8±0.3 day and in the control group on the 26.4±0.5 day. During
the following days of treatment there was a gradual closing of wound defects. The full
closure in the control group was fixed on the 36±0.5 day, and in animals of test groups
- on the 30±1.1 day of the wound process. The Index of Popova was negative from
the first day of the wound process and remained so till the 7th day, the animals of test
groups had – 1.4 %, and the animals of control group -1,6 %. It remained negative
till the 14th day of treatment – 5,8 %. The increase of the index value started in the
test group on the 14th day of treatment, it started to move upward rapidly by the 21st
day, followed by a decline by the time of recovery. The index of Popova was positive in
the control group only on the 21st day of treatment. By the end of treatment the index
of Popova was in the test group 4.0 % and in the control group 2.5 %. Staphylococci
predominate in the crops from fresh wounds. Gram-negative microbes were inoculated
in pure culture in single instances.
