Paragraph 19
An imported bull may be examined and tested for artificial insemination under the Artificial Insemination of Cattle (Animal Health) (England and Wales) Regulations 1985f1 of the Artificial Insemination of Cattle (Animal Health) (Scotland) Regulations 1985f2 provided that the EBL test taken within 70 to 74 days after landing is negative. If approved, semen may be collected and stored at an approved centre but may not be used until the bull or any other imported cattle in contact with it have passed the final post importation EBL test within 180 to 184 days after landing. If any imported animals on the same isolation premises as the donor bull fail the EBL test the semen must remain in isolation until all animals on that premises are released from isolation.
