Sažetak
The objectives of the current study were to investigate the influence of denaverine hydrochloride and carbetocin on softening and dilatation of the birth canal, the need for assistance during parturition, calf mortality, retention of fetal membranes, endometritis, and subsequent fertility. Altogether 200 animals (100 cows and 100 heifers) of the Simmental breed were divided into 2 groups: treatment (n=100) and control (n=100). Animals in the treatment group received denaverine hydrochloride and carbetocin (a maximum of twice for each, depending on the progression of labor) during delivery over a maximum of 4 waiting periods (30min each), whereas control animals experienced the same waiting periods but received no treatment. The treatment protocol had a positive influence on the ease of calving and postpartum reproductive health. The treatment increased the number of animals with the birth canal dilated by more than 25cm, and halved the need for any assistance at parturition. In addition, treatment decreased the occurrence of difficult calving, the need for episiotomy, the appearance of birth canal lesions, and clinical endometritis. The treatment protocol had an effect throughout the entire puerperal period, as treated animals conceived with fewer artificial inseminations (1.3 vs. 1.6 artificial inseminations/pregnancy) and sooner (67 vs. 78d open) compared with control animals. Denaverine hydrochloride and carbetocin administered in combination during parturition affected the progression and ease of calving, and thus the welfare of cows in labor and subsequently. However, further studies are needed to confirm the findings and to establish best practices.
