Management Practice and Comparison of Reproductive and Productive Performance of Dairy Cattle between Beneficiary and None Beneficiary of Estrus Synchronization and Mass Insemination in North Shewa Zone, Amhara Region. Ethiopia

Abstract

This study was conducted in North Shewa zone, with the general objectives to assess the overall management practice and comparison of reproductive and productive performance between beneficiary and none beneficiary of artificial insemination and estrus synchronization and mass insemination of dairy cattle in north shewa zone of dairy cattle. Data were obtained by interviewing 270 estrus synchronization and mass insemination beneficiaries and 135 none beneficiaries’ dairy farmers. Data were analyzed using SPSS version (20) ANOVA and Ms-Excel (2010). The reproductive performance of dairy cows in OSMI beneficiaries were age at first service (30.81±7.6), calving interval (6.9±5.2), lactation length (8.95±2.46), day open(5.3±3.18) and number of service per conception (1.5±0.38) whereas in none beneficiary age at first service (32.88±6.64), calving interval (18.18±5.8), lactation length (9.6±0.54), day open (5.17±3.43) and number of service per conception (1.22±0.54) months. The major factor affecting reproductive performance dairy cows are management,   nutritional status, genotype, and disease.
