Abstract
The study was conducted to assess the breeding practices of dairy cattle in Dejene, Lumme, and Machakel districts. In the study, the effectiveness of prostaglandin hormone was evaluated, and different factors that affected pregnancy in synchronized cows were detected. The study was conducted using a questionnaire survey and a participatory group discussion method. A total of 180 households participated in the interview. A structured questionnaire to describe qualitative and quantitative traits was used. 180 cows or heifers were injected with prostaglandin hormone to evaluate its effectiveness based on estrus induction, conception rate, and number of services per conception. Descriptive statistics, frequency distribution procedures, and the chisquare test were used. The results of the survey indicated that the mean herd size of cattle per household was 7.43 + 0.30, 6.20 ± 0.58, and 6.25 ± 0.69 in Dejene, Lumame, and Machakel districts, respectively. About 12.7%, 11.4%, and 25.1% of the respondents practiced AI technology in Dejene, Lumame, and Machakel, respectively, while 3.3% of the respondent’s practiced hormone plus AI technology only in Dejene and Lumame. On the contrary, about 7.1%, 7.1%, and 10.5% practiced hormones with AI in Dejene, Lumame, and Machkel, respectively. The primary objective of keeping their livestock milked in all the districts. About 66.7%, 61.7%, and 1.7% had a low perception concerning estrus synchronization practiced in the area.
