A Welsh beef farm has lifted the rate of conception at first service in its heifers by 10 since using bolus technology to aid heat detection. Rumen boluses are more usually associated with heat detection in dairy herds, but Farming Connect demonstration farmers Llion and Sian Jones are monitoring their performance and relevance in a beef herd.The pair, who farm at Moelogan Fawr, near Llanrwst, Conwy, had previously synchronised maiden heifers for artificial insemination (AI) using controlled internal drug release (CIDR) protocols. In 2019, this worked out at ￡29.51 a heifer in vet costs. They were keen to use a more natural approach to service, but wanted one that wouldn't rely on lengthy observation periods.
