Pengaruh Penambahan Tepung Jahe Merah (Zingiber Officinale Var. Rubrum) Dalam Ransum Terhadap Efisiensi Penggunaan Protein Pada Ayam Kampung Periode Pertumbuhan (16 - 22 Minggu) (the Effect of Added Red Ginger Meal (Zingiber Officinale Var. Rubrum) in The

Abstract

This study was aimed to determined effect of red ginger meal on the protein efficiency utility of growth period native chicken's diet. The material used in the study were female native chickens 16 weeks of age, a total of 100 chickens with an average body weight of 1.202,96 ± 8,92 g were placed in a battrey cage. There are 20 experimental units with each unit containing 5 chickens. Feedstuffs used in this study were corn, rice bran, fishmeal, soybean meal, white pollard, premix and red ginger meal. Given feed ad libitum. Chickens are classified into 4 block based on body weight, block I (1.000-1.100), II (1.101-1.200), III (1.201-1.300), dan IV (1.301-1.400). Experimental design used randomized block design (RDB) with 5 treatments and 4 groups; T0 = ration treatments without red ginger meal, T1 = ration treatments with red ginger meal 0,25%, T2 = ration treatments with red ginger meal 0,5%, T3 = ration treatments with red ginger meal 0,75%, T4 = ration treatments with red ginger meal 1%. The data obtained were analyzed using analysis of variance. The results after analysis of variance showed the addition of red ginger meal had no effect (P>0,05) in the protein efficiency of growth period native chickens diet
