Method and apparatus for detection of pregnancy in canids and equids

摘要

The invention relates to a method for early detection of pregnancy in canids and equids. The method involves introduction of a chemical, preferably from a group of chemicals essentially consisting of opioid antagonists, for use in elevating the concentration of the hormone prolactin of a pregnant canid or equid. Subsequent to introduction of the opioid antagonist to a suspected pregnant equid or canid, the concentration of the hormone prolactin may be measured for a determination as to the actual pregnancy of the animal. The prolactin concentration for an animal may be evaluated for a reliable determination of pregnancy as early as five days for canids and forty-eight hours for equids following insemination.
