Abstract

This study aims to determine the effect of substituting flour sunflower seeds (Helianthus annuus L.) in commercial feed with a particular concentration on performance broiler. This study used a completely randomized design. The sample consisted of 20 broiler chickens were divided randomly into 5 groups. The treatments were P1, P2, P3, and P4 respectively CP511 commercial feed containing sunflower seed flour 25%, 30%, 35%, and 40% as well as a control without substitution P0 flour sunflower seeds. The variable used is the feed consumption, final weight and feed conversion and then the results are analyzed by Analysis of Variance. Results obtained an average feed consumption value P0 is 79.76 grams, P1 is 77.90 grams, P2 is 77.35 grams, P3 is 77.98 grams, P4 is 77.58 grams. The results of the average value of the final weight of 1545.5 grams namely P0, P1 is 1296.5 grams, P2 is 1325.75 grams, is 1256 grams P3, P4 is 1203 grams. Results obtained from the average value of feed conversion is P0 1.37 , P1 is 1.69, P2 is 1.61, P3 is 1.71, P4 is 1.88. Based on the results it can be concluded that the substitution of sunflower seed flour in commercial diets not increase feed intake, body weight and can increase feed conversion. This study is recommended to substitute under 25% and fermented in advance to lower crude fiber content.
