Selection of beef cattle type characters in Bali young bull from smallholder farms through individual control for the purpose of artificial insemination

Abstract

Some of the male Bali cattle kept at the Artificial Insemination Center are the result of selection from the weaning process to become bulls. Therefore, this study aimed to determine the extent bulls selected from smallholder farms have the same quality spermatozoa as the males raised by the Institute for Artificial Insemination. The research method began in 2016-2018, which selected the performance of 50 heads, followed by a selection of biological characters, ejaculation, and livestock health in young bulls. Selected bulls were trained to collect their sperm and the quality of their sperm was examined macroscopically and microscopically. The results showed that 15 young bulls were selected by performance selection and four bulls were selected for selection based on the quality of frozen semen. Three bulls passed the selection to meet the frozen semen requirements of the Indonesian National Standard. The conclusion of this study is that the provision of males to the Institute for Center of Artificial Insemination can be done by selecting the best bull belonging to the farm community.
