The aim of the study is to evaluate the efficiency of a protocol for oestrus synchronization using a progesterone intravaginal device in Azawak cows reared in two different ranches in Niger. All subjects were submitted to artificial insemination using frozen semen from selected Azawak bulls. The concentration of progesterone was determined to assess the performance to pregnancy diagnosis, further confirmed by rectal examination. Any statistically significant difference according to oestrus behaviour and fertility was observed between the two husbandry systems.
Compared results of progesterone patterns and fertility in estrus induced Azawak cows in Niger

Abstract
The aim of the study is to evaluate the efficiency of a protocol for oestrus synchronization using a progesterone intravaginal device in Azawak cows reared in two different ranches in Niger. All subjects were submitted to artificial insemination using frozen semen from selected Azawak bulls. The concentration of progesterone was determined to assess the performance to pregnancy diagnosis, further confirmed by rectal examination. Any statistically significant difference according to oestrus behaviour and fertility was observed between the two husbandry systems.
