A cross sectional study was conducted from August 2016 to June 2017 to determine evaluation of artificial insemination services efficiency in selected sites of west Gojjam zone. Totally 180 respondents (156 farmers, 20 animal health and production professionals and 4 artificial insemination technicians) were interviewed. The study was conducted by questionnaire survey, Semen motility, retrospective data and monitoring of inseminated animals. All inseminators (100%) in both districts have performed their activities on weekends, governmental and religious holidays. In Mecha half 1(50%) AITs followed higher responsible bodies decision to select and inseminate the breed type of the semen whereas on station 2(100%) decided by themselves. 2(100%) in Mecha and 1(50%) in Andassa responded proper controlling mechanisms were taken place by responsible bodies thoroughly and timely. In Mecha Production and health experts 12(100%) responded all AI service documents were kept timely and properly by all concerned bodies and in Andassa 7(87.5%). All Animal production and health professionals (s) 12(100%) supported all AI service and how ever APHPs in Andassa 6(75%) did not support. Experts in Mecha 5(41.7%) and in Andaassa 6(75%) responded lacks of semen and liquid nitrogen were the major problems of conventional AI service. Costumer respondents 72(94.7%) in Mecha used the technology without interruption and 45(56.2%) in Andassa. The majority of farmers 66(86.8%) in Mecha and 46(57.7%) in Andassa respectively farmers in satisfied with overall AI service in their surroundings. The mean result of the semen motility in Andassa 10(45%) was better than in Mecha 10(40%). In Mecha Conception Rate (CR) 8(80%), Number of Service Per Conception (NSPC) (1.2), Non Return Rate (NRR) (100%), and Conception Rate at First Service (CRFS) 8(80%) result were better than CR (70%), NSPC (1.4), NRR (80%), and CRFS (70%) respectively of Andassa. The retrospective data only in the year 2014 the conception rate (42.1%) and calving rate (34%) result of Andassa were better than Mecha (12.4%) and (19.5%) respectively. Generally, the study indicated that artificial insemination was not done well successfully in both districts. There for, both study sites need thorough follow up on the technology especially in Andassa. Key words: Artificial insemination, Semen, West Gojjam zone
