Abstract:
The aim of the study was to assess productive and reproductive performance of crossbred (Zebu x
Holstein-Friesian) dairy cows and factors affecting their performance in Jimma town, Oromia State, Ethiopia. A
total of 54 small-scale dairy farm owners were randomly selected and interviewed with pre-tested structured
questionnaire to obtain information on the productive and reproductive performance of cows. A follow-up
study was also conducted to obtain milk production based on lactation stages. The results of the study showed
that from the follow-up study, the mean daily milk yield for the first, second and third stage of lactations was
7.01± 2.73, 5.55±2.83 and 3.50±1.64 liters per cow, respectively. The milk yield was decreased significantly in the
third stage of lactation than that of first and second (P<0.01). The milk yield was observed significantly (P<0.01)
higher in the morning than in the evening for the three stage of lactations. From the survey results, the mean
milk production per day/cow and per lactation was 8.45±1.23 and 2314.45 litres, respectively. The overall average
lactation length was 9.13±1.99 months The mean age at first service(Months), age at first calving (year), days
open till conception, calving interval (Months) and number of services per conception from survey data were
24.30±8.01, 3.05±0.65, 21.36±3.84 months and 1.56±0.57, respectively. The present study showed that productive
and reproductive performance of crossbred cows owned by small-scale dairy producers in Jimma town was low.
Thus, there is a need to improve feed supply, health care and services, access to artificial insemination, proper
breeding management and supply of improved genotypes in order to improve the performance of dairy cows
