T/CVMA 1-2018 Poultry Leukemia Eradication Technical Specification
Basic Information
Scope
Scope: This standard specifies the technical specifications related to the detection and purification of poultry leukemia in breeding flocks, and the maintenance of their purified status. The detection and purification techniques listed in this standard for all growth stages of breeding chickens are mainly applicable to original breeding flocks (or core flocks) with a need for poultry leukemia purification. Other types of flocks can also refer to and implement these techniques. The techniques listed for maintaining the purified status of poultry leukemia are applicable to flocks that have achieved poultry leukemia purification. Main technical content: This standard specifies the technical specifications related to the detection and purification of poultry leukemia in breeding flocks, and the monitoring and maintenance of their purified status. It mainly includes detection methods for newly hatched chicks, late chick rearing, early laying, and pre-breeding selection; technical requirements for the selection and incubation of eggs; and measures for monitoring and maintaining the purified status of flocks. It also specifies techniques for virus isolation and identification in rooster semen, identification of poultry leukemia virus contamination in attenuated vaccines, and rapid detection of poultry leukemia p27 protein antibodies.
