The materials used in this research were 64- day old chicks (DOC) of broiler that were maintained for five weeks. Chickens were divided into 16 plots of cages where each plot was filled with 4 chicken experiments. This study used a completely randomized design consisted of four treatments and four replications. The treatments were control (P0), level of 2% of katuk leaf powder (P1), level of 4 % of katuk leaf powder (P2), and level of 6% of katuk leaf powder (P3). Parameters observed were feed consumption, body weight gain, and feed conversion. The result showed that the addition of katuk leaf powder in the ration of each treatment gave the same amount of consumption. The level of 2% of katuk leaf powder could improve the weight gain of broiler chicken Keywords: Broiler, katuk leaves, consumption, weight gain, feed consumption INTRODUCTION Broilers are a type of superior breed that results from crossing produced from male Cornish strains with large females, namely Plymouth Rocks which is a high- boned white strain (Rasyaf, 2008). The broiler is a meat race which is still a top priority in the poultry industry to meet the needs of human-animal protein. Some of the superior properties of broilers such as it does not require a large place in maintenance, highly nutritious, fast growth, and efficiently convert food into the meat so that it can reach a heavy selling age with high body weight. Broilers can produce meat in a shorter time than other types of chicken, so the excess chicken is positively correlated with the need for animal protein in society that continues to increase. However, fast meat production in broilers requires complete dietary support rich in nutrients. So that effort is needed to increase broiler chicken production through ration modification with quite high nutritional content. Feed ingredients that have high nutritional and nutrient content are not cheap, so it needs efforts to utilize alternative feeds that are cheaper and more affordable but still have high nutritional value. One of them is the use of katuk leaf flour, where katuk leaf flour is rich in nutrients, several vitamins, proteins, and other minerals that are needed by poultry for its growth. Based on the description above, the purpose of this study is to determine the effect of katuk leaf flour in rations on consumption, weight gain, and conversion of broiler rations. MATERIALS AND METHODS The material used in this study were 64 Day old chick (DOC) broilers, and the feed ingredients used were yellow corn, rice bran, RK24 concentrate, katuk leaf IJAAS Indonesian Journal of Animal Agricultural Science http ://ojs.uho.ac.id./index.php./ijaas Ind.
