Artificial insemination (AI) is an important tool for genetic improvement in livestock. The success rate of AI is influenced by many factors, including the semen quality used for inseminating the female (1). Fresh semen is processed and stored in liquid nitrogen before being distributed to the farmers. The use of liquid nitrogen was to freeze the semen for long-term storage. Environmental factors such as elevated temperature and human errors can affect the semen quality during semen processing. Therefore, the semen processing handling is critical to maintain the sperm quality. Semen quality evaluation during processing is crucial to make sure the semen is in good condition before stored and distributed. To ensure even minimal success, proper diluent, sperm dilution rate, cooling rate and thawing rate are essentials to maximize the post-thaw recovery of sperm and consequently fertility (2). 

            In Malaysia, National Institute of Veterinary Biodiversity (NIVB) at Jerantut, Pahang is responsible for producing frozen livestock semen to be distributed to the department’s AI personnel for AI extension services to the farmers since 1989. During this period, NIVB has continuosly optimizing the method for semen processing and storage. Some studies have been done including the effect of cryostorage duration on sperm structure deformity (3) and the effect of different extender on semen quality (4). The objective of this study is to evaluate the goat semen quality using standard procedures set by the NIVB for goat semen. Semen studied are from fresh, chilled and frozen samples.
