The effect of katuk (Sauropus androgynus) and gamal (Gliricidia sepium) supplementation on the dry matter digestibility, organic matter digestibility, and milk quality of Friesian Holstein

Abstract

Abstract This study aims to determine the effect of katuk and gamal supplementation on dry matter digestibility, organic matter digestibility, and dairy milk quality of Friesian Holstein. This study was conducted at the Dairy Farm in Enrekang Regency. Sixteen heads of Friesian Holstein dairy cows having body weight ranged between 350 and 400 kg were randomly assigned to one of four treatment diets according to a completely randomized design (CRD). The number of replication for each treatment was four giving the total number of the experimental unit of 16. The treatments were supplementation of the ration consisted of forages (60%), concentrate (25%), and gamal leaves (15%) with either 0 g (P0), 135 g (P1), 155 g (P2), or 175 g (P3) of katuk. The results of the study indicated that supplementation of a ration containing Gamal ( Gliricidia sepium ) with different levels of katuk ( Sauropus androgynus ) significantly influenced the digestibility of dry matter and organic matter as well as the milk quality. Among the treatments, the P2 treatment (katuk supplementation of 155 g/d) showed the highest significant effects on improving the feed digestibility of the ration and the quality of milk.
