Improving the performance and physical condition of the intestines of the Lohman MB202 broiler chicken intestine by using fermented local herbs

This research was conducted to find alternative antibiotics using local microorganisms which are expected to act as probiotics in the digestive tract. The local microorganisms used came from 3 types of herbs from 3 types of land. Crown flowers represent coastal land, ferns represent plantation land and lemongrass represents highland land. This study used an experimental method using a completely randomized design (CRD) with 5 treatments and each treatment had 4 replications (each replication contained 200 chickens). Treatment T1 water, T2 fermented crown flower, T3 fermented fern, and T4 fermented fragrant lemongrass each as much as 2 ml/liter of drinking water. The parameters measured were the performance and gut physical (village height and gut histology) of broiler chickens. Performance is body weight, weight gain, ration consumption, ration efficiency, performance index, and mortality. While the physical condition of the intestine is in the form of villi height and intestinal histology. The results showed that fern as a fermented herb significantly increased the performance index and improved the condition of the intestinal villi. However, the low mortality was significantly indicated by the fermented crown flowers. In conclusion, local fermented ferns have the potential as local microorganisms to replace the role of antibiotics because they can improve the performance and condition of the digestive tract of broiler chickens.
