Broiler chickens are one of the animal protein source which attracted many people. The high cost of feed is one of the major obstacles for chicken farmers, so farmers must be able to find an alternative way to reduce feed costs. Seeds of jackfruit (Artocarpus heterophyllus) is an agricultural waste that has a high nutrient value. Jackfruit seed waste utilize as additional feed for broiler chickens is expected to be an alternative way to improve the performance of livestock, especially broiler chickens and also to reduce production costs.

Cobb broiler chicken strain used in this research were divided into five groups, consist of control group (without addition of jackfruit seed flour), group with 10% addition of jackfruit seed flour, group with 20% addition of jackfruit seed flour, group with 30% addition of jackfruit seed flour, and group with 40% addition of jackfruit seed flour. Each group uses five repetitions. Chickens were treated using jackfruit seed flour at the age of 15 days up to the age of 35 days, then calculating the feed consumption, body weight gain, and feed conversion ratio of these Cobb broiler chickens strain.

The results of One Way Anova showed that jackfruit seed flour (Artocarpus heterophyllus) as a feed addition didn’t have significant effect (p > 0,05) on feed consumption, body weight gain, and feed conversion ratio of these Cobb broiler chicken strain. The conclusion of this research is that jackfruit seed flour (Artocarpus heterophyllus) can be use as alternative feed addition in order to reduce feed costs.
