The productivity comparison between bligon and kejobong goats in indonesia, based from on-farm and on-station research

This paper presented the productivity comparison between Bligon and Kejobong goats, two local goats developed by Indonesian smallholder farmers with traditional management. On-farm research was conducted for 12 months at the two farmer groups in Yogyakarta and Central Java with a total 75 farmers as respondents. Seventy-five does with 95 kids of Bligon goat, and 66 does with 87 pre-weaning kids of Kejobong goat were regularly monitored for body size, reproductive performance and pre-weaning growth. On-station (laboratory) research was done using 9 male Bligon and 9 male Kejobong goats of 6-8 months, kept for 5 months and investigated their dry matter (DM), crude protein (CP), total digestible nutrients (TDN) intakes, and average daily gain. The feed used consisted of groundnut leaves and rice bran. Feed was given 3.5 of body weight (70 groundnut and 30 rice bran) on a dry matter basis. The result from on-farm research showed Kejobong goats, either male or female had higher body length and rump height (P<0.01) than Bligon kids at different age categories. Service per conception, gestation period and postpartum mating of Kejobong goats was higher (P<0.01) than Bligon goats, while litter size did not significantly differ. Birth weight and pre-weaning mortality of Bligon and Kejobong goats was the same while weaning weight and average daily gain (ADG) were significantly higher (P<0.05) in Kejobong kids rather than Bligon kids. The result from on-laboratory research showed that feed intake (FI), dry matter intake (DMI), crude protein intake (CPI), and intake of total digestible nutrients (TDN) did not significantly differ between male Bligon and Kejobong goats, while ADG, feed conversion and feed cost per-gain was also the same. In conclusion, Kejobong goats had a potentially better performance in terms of growth, feed intake and feed efficiency compared to Bligon goats. However, poor management in terms of feed quality offered by the farmers makes that potential unpleasant and caused low reproductive performance of Kejobong does.
