  "abstract": "<p>This study was conducted in urban and Pre-Urban Areas of Adama, Oromia Region, Ethiopia with the objective of the studying dairy cattle productivity and AIpractices in the study area. The study involved cross sectional survey, retrospective and monitoring study. A total of 130 dairy cow owners were randomly selected and interviewed with pre-tested semi-structured questionnaire. For monitoring study lactating cows (N=50) and newly born calves (N=50) of local and cross breed were purposively selected and monitored for milk yieldgrowth of calves until weaning. For retrospective study, data were collected from record book of the AI covering year 2013 to 2017. Survey data were analyzed using SPSS statistical package (SPSS version 20) and Monitoring data were analyzed by SAS Version 9.1. The result showed that both AI and natural mating was used for breeding cattle. From the survey results, the mean age at first service was 3.37 &plusmn;0.07 and 1.62&plusmn;0.09 years for local and crossbreed respectively. The mean AFC, CI, NSPC, DO, MPD, LL, Longevity, for local and crossbreed was 4.17 &plusmn;0.07 and 2.32&plusmn;0.11 years, 1.32&plusmn;0.06, 1.09&plusmn;0.03 year, 1.15 &plusmn;0.05, 2.60&plusmn;0.26, 135.42 &plusmn;4.15, 91.5&plusmn;5.76 days, 2.57 &plusmn;0.14, 11.92&plusmn;0.52 liter, 7.45 &plusmn;0.22, 9.63&plusmn;0.21 months, and 14.12 &plusmn;0.1714.06&plusmn;1.37 years and gives mean 9 &plusmn;0.17, 9.74&plusmn;0.32 calves, within this life time respectively.The result of monitoring study showed that the average daily milk yield for local, 50%-75% and &gt; 75% caws was 2.59, 8.6 and 14.10 liters, respectively. And average for crossbreed was 12.68liter. Daily milk yield of local cows found in monitoring study was support milk yield found in survey study. The average 305 day milk yield for local and their crossbred of 50%- 75% and &gt;75% was 786.562&plusmn;110.43, 2638.52&plusmn;496.70, and 4410.15&plusmn;537.72 liters, respectively and average for crossbred was 3524.34 liters. Average birth weight of local and crossbreed calves were 19.83&plusmn;2.43 and 29.30&plusmn;3.92 kg, respectively. The overall mean of WW of local and crossbreed calf was 48.11&plusmn;7.19 and 64.10&plusmn;8.20 kg, respectively and ADWG was 0.363 kg with ADWG for male and female of 0.395kg and 0.325 respectively. Cost and unavailability of improved breeds, high cost of feed, shortage of AItechnicians and semen was the major constraints hindering AI service delivery system and dairy production in the study area. Therefore, the reproductive performance of dairy cows in the area should be improved through appropriate heat detection, improved feed development, and introduction of improved breeds, improved level of husbandry recommended.</p>",
