Abstract
High Quality Feed (HQF) is a formula feed comprising the feed material that has high quality. Purpose this research is to find a formula HQF that can be applied and can be widely used in laying chicken farms, primarily related to the case of Highly disease Pathogenic Avian Influenza (HPAI) that can reduce economic losses due to morbidity and high mortality. Because handling unfinished AI through vaccination, is expected by the HQF can help boost the immune system of poultry. In this stage developed feed formulations that contain ricebran fermentation with the best nutrient content, the building block of concentrates and Spirulina as immunomodulatory, this stage aims to determine the effect of HQF formula tested on chickens Isa Brown laying strain to determine the effect of the growth performance by calculating the feed conversion ratio. The aim of this research was to investigate effects of fermented ricebran to evaluate the protein efficiency ratio of layer chicken by in- vivo method. Material research were: chicken layer Isa Brown strain, feed stuff: maize, extracted soybean, fishmeal, methioninpremix vitamin, premix mineral, DCP, L-Lysin, oil, non fermented ricebran, fermented ricebran, feed additive. Eight different feed formulation are: control/Po(crude protein(CP):18.14%, Pi (CP: 18.34%), P2(CP: 18.54%), P3(CP:18.74%), P4(CP: 18.41%), P5(CP: 18.61%), P6(CP: 18.81%), P7 (CP: 19.00%). The result of research showed that Po was different significantly (p<O.05) in protein efficiency ratio of layer chicken by in- vivo method. The highest protein efficiency ratio was P7(2.83),
