Reproductive and morphological performances of stallions in District of Karo, North Sumatera, Indonesia

[摘要] The objective of this study was to investigate reproductive and morphological performances of stallions in District of Karo, North Sumatera, Indonesia. Body measurements and and semen were taken on 12 stallions from four villages in District of Karo, North Sumatra, Indonesia. There were two villages in Merdeka Sub-district i.e. Jaranguda and Merdeka; and two villages in the Berastagi Sub-district, i.e., Gundaling and Berastagi. Data were entered in Microsoft excel, checked, organized and processed for further analyses. Means with standard errors (SE) for different traits were subjected to the standard analysis of variance technique. The results showed that semen quality of stallions performed in macroscopic and microscopic examination were in good quality with colour of semen was white grey, neutral pH, 74% dilute, 73.3% motility, 13.40 x 107 concentration with their semen abnormalities observed were normal. The morphology characteristics of stallions in District of Karo showed an appearance with a variation coefficient value below 10% which means the measurement value of horizontal horse morphology in good condition. The results support horse breeders to cross-breed periodically their stallions with local horses in District of Karo because their variation coefficient showed good quality semen with uniform value.
