Pengaruh Suplementasi Hidrolisat Bulu Ayam dan Mineral Organik terhadap Kecernaan Zat Makanan, Pertambahan Bobot Badan, dan Efisiensi Ransum Kambing Peranakan Etawah Jantan

The objective of research were to evaluate the effect of supplementation of hydrolyzed of feather meal, organic macro mineral (Ca and Mg-Polyunsaturated Fatty Acid /PUFA) and organic micro mineral (Zn, Cu, Cr, and Se-lysinat) to improve nutrient digestibility, daily gain and rations efficiency of male Etawah cross goats. The research were used 20 male Etawah cross goats. Random block design were used this research was used, with 4 treatments and 5 replications. The treatments were arranged : R0= 40 % of forage + 60% concentrates; R1= R0 + 3% of hydrolyzed of feather meal ; R2= R1 + organic macro mineral (Ca and Mg -PUFA); R3 = R2+ organic micro mineral (Zn,Cu, Cr, and Se-lysinat). The results showed that mixing treatment of hydrolyzed feathers meal, organic macro and micro mineral (Ca and Mg-Polyunsaturated Fatty Acid /PUFA and Zn, Cu, Cr, and Se-lysinat)/R3 had significantly effect of increasing organic digestibility, digestible energy, daily gain and rations efficiency of male Etawah cross goats
