Two methods of treatment of cows with ovarial cysts | Dva spôsoby ošetrenia ovariálnych cýst kráv

Goal of work was to compare two methods of treatment of cows ovarian cysts. In experiment have been assigned 275 cows of Holstein bred, they were 2-6 years old. Cows milk production was 8,350 kg per year. Cow with ovarian cysts were randomly ranking into two groups in corformity with diagrams of the treatment. Diagnostics of the ovarian cyst was realised by transrectal ultrasonografic examination by 5 MHz linear probe. Into group 1 were assigned cows (152), that were treated by GnRH on 0th and 7th day (50 micro g, im; Supergestran), PGF2a on 14th day (25 mg, im; Oestrophan), GnRH on 16th day (50 micro g, im). On 17th day cows were inseminated (about 20±4 hours after final treatment). Into group 2 were assigned cows (123) treated Oth day by GnRH (50 micro g), on 7th day by PGF2 a (25 mg) and 9th day by GnRH (50 micro g). Cows were inseminated on 10th day (about 20±4 hours after final treatment). Assigned cow 0th day and 7th day were examinated by ultrasonografy. On 7th day after primary treatment by GnRH, there were found significantly better results into group 2 (P lt 0.05 ). Cows 70 days pp, they had about 6,27% CL presented more. In cows which were 101-150 days pp, it was difference 22.15%. Between groups, was found this difference 32.66%. Cow of both groups treated between 71t-100 days of puerperium, they had identical occurrence of the preovulatory follicles. Significantly better effectivity after treatment (P lt 0.05) was detected into group 2 (29.82% preovulatory follicles). More preovulatory follicles was found in cows which were 70th day of pp - 6.93% (P lt 0.05) and also on 101-150 day pp - 21.38%. From treated animals after insemination were gravid in 30th day of pregnancy 24.34% cows, resp. 26.01% cows. Most cows were gravid from group animals treated 71-100 days of the puerperium (13.82%, resp. 10.57%). Both diagrams of the treatment are as an effective way of therapy for cows ovarian cystic disease.
