Optimizing the Performance of the Small Intestine of Joper Chickens and KUB Chickens Using Herbal Medicine

This research aims to see the small intestine performance of KUB (Kampung Unggul Balitbangtan) and Joper (Jowo Super) chickens given herbal medicine. Amount of 200 chickens consisting of Joper and KUB chickens, rearing was carried out using open-house system cage. The feed used is commercial feed. The herbal medicine was produced by the UMM experimental farm, given through feed as much as 1 % of the total feed. The treatment in this study was the provision of herbal medicine in the feed and no herbal medicine in the feed (control). The variables observed were the length and relative weight of the small intestine (duodenum, jejunum, ileum). The data obtained was analyzed descriptively. Joper chickens given herbs and those without herbs gave relatively similar and normal small intestine weights. Meanwhile, in KUB chickens, chickens given herbal medicine had higher jejunum and ileum lengths compared to controls with values of 1.47 % and 1.17 % respectively. This research concludes that herbal medicine can increase the length and weight of the small intestine of KUB chickens but has no effect on Joper chickens.
