Abstract
This study aims to determine the effect of katuk and gamal supplementation dry matter digestibility, organic matter digestibility, and dairy milk quality of Holstein friesian. This study was conducted at the Dairy Farm in Enrekang Regency. The study was arranged by completely randomized design (CRD) consisted of 4 treatments and 4 replications. The supplementation contained forages (60%); concentrate (25% for each treatment); gamal leaves (15%) and katuk leaves (135 g, 155 g, 175 g) supplemented to 16 dairy cattle units with body weight of 350-400 kg. Katuk (Sauropus androgynus) and Gamal (Gliricidia sepium) Supplementation shows significantly influence on the digestibility of dry matter and organic matter as well as milk quality. The P2 treatment shows best quality and can improve digestibility and better milk quality.
