The interest of sheep and goat breeders in increasing productivity and implicitly profitability has materialized through the modernization of the traditional exploitation system. To increase productive performance, breeders resort to natural mating with breeding males. The epizootic situation of recent years, respectively the sanitary-veterinary restrictions as a result of the evolution of infectious diseases (Bluetongue, PMM) have limited the circulation of males with implications for reproduction management. An alternative to solving this impediment is to resort to artificial insemination with semen from breeding males. In this sense, Palas Sheep and Goat Breeding Research and Development Institute, in partnership with National Association of Goat Breeders in Romania ”CAPRIROM”, carries out research activities in order to establish methodologies for preserving ram and goat seminal material in frozen form that would allow the creation of a sperm cryobank from valuable males. When examining frozen-thawed semen from Palas Merino rams, processed during the breeding season, a total motility ranging from 43.2 to 64.1% and a progressive motility ranging from 31.8 to 47.7% were recorded, while in the off-breeding season, values of 39.4-44.5% for total motility and 27.1-32.5% for progressive motility were obtained. The total and progressive motility values from Palas Milk rams had a very high variability.References
