The effects of different PMSG doses on estrus behavior and pregnancy rate in Angora goats

Animal, 2019
Artificial insemination protocols depend on efficient behavioral estrus detection and insemination time in Angora goat. Therefore, we aim to determine the accuracy of an estrus scoring system in Angora goats with different PMSG doses during the breeding ...
