Abstract
In high-productive dairy herds oestrus returning and silent heat is a frequent problem. In one of herds with the problem with oestrus detection the animals was divided on three groups. In the first group during insemination the LH-RH (50 μg lecirelin-Supergestran ®) was administrated. In the second group for oestrus synchronisation two injections of cloprostenol (Oestrophan®) with the interval of 11 days was used and the cows was inseminated in 78-82 h after second injection. In third, control group any drugs was administrated for oestrus synchronisation. The percentage of pregnant cows noted 8 week after insemination amounted 50%, 66,6% and 43% respectively. Obtained results suggest that in herds with oestrus detection problem insemination after twice injections of prostaglandin could give a positive effects.
