True diagnosis

ACCURATE, cost-effective pregnancy diagnosis within 40 days of service or insemination is promised by the Agritech doppler cattle diagnosis unit, claims Agritech.

A probe is inserted into the cows rectum, and ultrasound allows the operator to hear the increased blood flow in the uterine artery, a positive sign of pregnancy, says the firm. The equipment cannot give false positive diagnosis, according to Agritech. The portable equipment, operated by a rechargeable battery, comes with a three-year guarantee and costs £495 (01243-827840).
