Abstract

Artificial insemination (AI) is a reproductive biotechnology that has many advantages. Bitch mating in inappropriate period is the most common cause of failure in breeding programs, therefore, to be successful in AI, it is essential to monitor correctly the estrous of the female that will be inseminated. The measurement of plasma progesterone is one of the main methods to detect the ovulation time. The dosage of progesterone in biological fluids, such as saliva, is a useful, accurate and noninvasive indicator used to monitor ovarian activity in different species. This study´s objectives are to dose plasmatic and salivary progesterone levels of 15 bitches to be submitted to AI, verify a positive correlation between them and evaluate the use of saliva as a method to monitor the right time to mat or artificially inseminate bitches.
