Effect of Katu Leaf (Sauropus androgynus) Extract Supplementation on Milk Quality and Yield of Bali Cow Fed Rice Straw and Natural Grass Basal Diet

Abstract

Milk yield and quality of bali cows given supplementation of katu leaf (Sauropus androgynus L Merr) extract were investigated. A completely randomized design with three treatments and three replications were used in this experiment. The result showed, milk yield of bali cows in treatments B (0.5% w/bw supplementation of katu leaf extract) and C (0.1% w/bw supplementation of katu leaf extract) were respectively 43.22% and 9.63% higher than that of bali cows in treatment A (0% w/bw supplementation of katu leaf) (P>0.05%). Protein content, fat percentage, lactose content and total solids of milk of bali cows given katu leaf extract supplement were ranging from 3.42-3.55%; 6.37-6.67%; 3.77-3.93% and 16.67-16.95% respectively. There were no significant differences in protein, fat, lactose and total solid percentages of bali cows milk in treatments A, B and C (P>0.05) Keywords: milk yield, quality, bali cow, katu lea
