This study was conducted to evaluate effect of single and double dose injection of prostaglandin hormone in Adaberga, Ejere and Metarobi districts. 130 cows or heifers were injected single and double dose of prostaglandin to evaluate the effectiveness based on estrus induction, conception rate and number of services per conception. Cow/heifers which do not respond by single injection were reinjected another single dose of prostaglandin. Descriptive statistics, Frequency distribution procedures and Chi-Square test were used. Among cows or heifers treated with single dose of prostaglandin 43.68%, 29.23% and 27.69% open heat, silent heat and none response respectively. There was significant difference between breeds in silent responded cows/heifer and local silent responded cows/heifers were greater than the crossed responded cows/heifers. Estrus rate was estimated to be 61.36%, 81.82%, and 73.81% in Adaberga, Ejere and Metarobi for single dose of prostaglandin injection respectively. There was significance difference between AITS on estrus rate. The conception rate for single dose of prostaglandin was 40.7%, 72.22% and 64.52% in Adaberga, Ejere and Metarobi whereas the number of services per conception was 2.46, 1.56 and 1.55 in Adaberga, Ejere and Metarobi respectively. The overall conception rate and number of services per conception for single dose of prostaglandin injection was 57.44 % and 1.74 respectively. The overall estrus rate, conception rate and number of services per conception for both single and double dose of prostaglandin injection was 83.85%, 52.29% and 1. 91 respectively. Improvements in facilities and management should be necessary before implementing effective estrous synchronization and mass artificial insemination program. The skill and knowledge-based training for enhancement estrus synchronization must be given for both the farmers and implementers to enhance perception and adoption of the technology. The AITS must update recent skills and knowledge. Finally, evaluating the effect of single and double dose of prostaglandin injection serve as a basis for improvement of fertility of dairy cows in turn it will help for designing appropriate breeding strategies of dairy cattle.
