Abstract

This study was conducted to determine the relationship of birth weight of calves, sex ratio of the calves, and the age of the dam to the length of pregnancy in buffaloes resulting from artificial insemination in Kampar District. The method used in this research is the descriptive method by displaying the average and standard deviation. The total number of buffaloes that were artificially inseminated in 2018 and gave birth in 2019 was 21 buffalo-cows. Data were analyzed with the Pearson Product Moment (PPM) correlation. The parameters measured in this study were the length of pregnancy, calf birth weight, calf sex ratio, and dam’s age. The results showed a positive correlation between the birth weight of the calves, sex ratio of the calves, and the age of the dam to the length of pregnancy of 1.4%, with an average length of pregnancy, calf birth weight, and sex ratio of 351.81 days, 27.38 kg, and 1: 1 respectively.

Kinerja Reproduksi Ternak Kerbau (Bubalus bubalis) pada Usaha Peternakan Rakyat di Kabupaten Klaten Provinsi Jawa Tengah

“…Induk yang bunting dengan anak kerbau jantan akan mendapat lama bunting yang cenderung lebih lama dari anak kerbau betina. Pada indukan muda lama kebuntingan akan terjadi relatif lebih pendek daripada indukan yang berumur tua (Yendraliza et al, 2020). Lama kebuntingan yang optimal dapat juga dipengaruhi oleh pakan ternak.…”
