This study aims to optimize the utilization of agro-industry waste through supplementation of hydrolyzed chicken feather and organic minerals in the ration as an effort to improve the digestibility of crude protein and crude fiber in ruminant. This study used 3 beef cows. The experimental design used is a Latin square design 3x3 with 3 cows as a rows and 3 periods as columns. The treatment given is R0: basal diet (30% + 70% forage concentrate) ; R1: basal diet + 3% hydrolyzed chicken feathers ;

The data obtained were tested by analysis of variance. The results showed that the effect of the addition of hydrolyzate chicken feathers 3% NaOH and organic macro and micro minerals in the diet was not significantly different (P> 0.05) on the digestibility of protein and crude fiber in the ration of cattle rations.
