Abstract

The aims of this study was to know about reproduction efficiency such as service per conception, conception rate, calving rate, service period and calving interval after artificial insemination on beef cattle in East and West district, Kabupaten East Lombok on 2012. The method to determine value of reproduction efficiency by artificial insemination was collecting primary and secondary data about number of inseminated beef cattle, number of pregnancy, number of birth, interval between birth and pregnancy and number of calving interval. Then, data were processed and presented as tabulated and charts to get service per conception, conception rate, calving rate, service period and calving interval and supported by average value. The observations showed that service per conception in East district was 1,17; conception rate was 79,45%; calving rate 49,70%; service period was 2,78; and calving interval was 12,05. West district showed that service per conception was 1,23; conception rate was 82,66%; calving rate 66,31%; service period was 2,91; and calving interval was 12,67. Based on data, West district was better than East district because all of the factors which influence reproduction efficiency can be controlled.
