Sažetak
By this research we aimed to establish how much service period can be shortened in dairy cows by control of puerperium. We have encompassed eighty cows on two mini farms in the Counties of Varaždinska and Međimurska. Forty cows divided in two groups were observed on each mini farm. The experimental group of cows on each farm was subject to rectal examination and ultrasound on the 20th and 40th day after calving and immediately treated if where required. We examined and inseminated cows only at the owner’s call without prior controls or therapy. In the Simmental cows, average duration of service period in the control group was 121, 6 ± 8, 83 (M±S.E.M.) days, and conception rate was 2.6. While in the experimental group, service period was 108, 5 ± 6, 12 days and conception rate was 2.4. In the Holstein cows, service period in the control group was 156, 2 ± 12, 45 days and conception rate was 3.3. In the experimental group, service period was 116, 1 ± 8, 47 days, and conception rate was 2.2. In this groups of Holstein cows, a significant difference (P<0.05) was determined for duration of service period and for conception rate. We have concluded that regular control of puerperium may shorten the service period in both animal groups. That is particularly visible in Holstein cows due to their high selectivity to dairy production but also their genetic tendency to metabolic disorders and peripartal diseases.
