Effect of the Nutrient Concentrate in Ration on Performance of Local Chickens

Abstract

Efforts towards improving the quality of shrimp waste are through bioprocess using Bacillus licheniformis service, Lactobacillus sp., and Saccharomyces cerevisiae to obtain a quality product (Nutrient Concentrate) to meet the needs of local chicken's nutrition. The study's objective was to obtain an adequate level of use of Nutrient Concentrate in the local chicken ration during the growth phase. Research using the experimental method in the laboratory. The experimental design used was a complete randomized design, consisting of 6 treatment rations (R0 = low protein ration (15%), R1 = Ration containing 5% concentrated nutrient, R2 = Ration containing 10% concentrate nutrient R3 = Ration containing 15% nutrient Concentrate R4 = Ration contains 20% concentrate nutrient, and RS = high protein ration (18%) and each is repeated 5 times. The data were analysed by variance, and the differences between treatments were tested by Duncan's multiple range test. The results of the research were: (1) The best growth of local chickens (consumption of ration, weight gain, and ration efficiency) was given by ration containing 10% concentrate nutrient (15% ration protein) and the equivalent of high protein ration (protein ration 18 %), and (2) Nutrient concentrates can be used up to 20% in a local chicken ration of growth phase without affecting chicken health (erythrocytes = 1.87-2.20 × 106, leukocytes = 29.08-37,72 × 103, and haematocrit = 30.80-33.80%).
