The Influence of Individual Factors on the Characteristic and Production of Frozen Semen of Bali Cattle

Individual difference is one of the factors that influence the semen quality during ejaculation. The study aimed to analyze the influence of individual factors on the characteristic and production of frozen semen of Bali cattle.  One hundred fifteen ejaculate semen samples were collected from 10 Bali cattle using an artificial vagina. The semen color, consistency, pH, volume, abnormality, motility, concentration, total sperm (TS), and total motile sperm (TMS) were analyzed. The frozen semen was evaluated for motility before freezing (MBF), post thawing motility (PTM), total motile sperm form PTM (TSMP), and frozen semen production. Data were analyzed statistically using one-way analyzed variance to obtain the difference between individuals. The results showed the semen was a milky color with a thin, medium, and thick consistency. The semen pH and motility were not significantly different between individuals (p>0.05). In comparison, the individual differences affected (p>0.01) on volume, abnormality, concentration, TS, and TMS. The individual differences of frozen semen also affected MBF, PTM, and TSMP. The characteristics and production of frozen semen were influenced by individual differences, which can then be used to determine superior males
