Abstract
HyCole and HyLa rabbits were imported by the Indonesian Research Institute for Animal Production (IRIAP) in 2012 and 2013. Importation were done to overcome raising demmand on broiler rabbit. HyCole and HyLa rabbits were known as best broiler rabbit and had potentiality as genetic resources to develop Indonesian broiler rabbit like new zealand white that already adapted in Indonesia. The aim of this study was to characterize phenotype of HyCole and HyLa rabbits, in order to evaluate their adaptability in tropical environments, and as genetic resources to develop Indonesian broiler rabbit like new zealand white that were already adapted in Indonesia. Research were held at Indonesian Research Institute for Animal Production using 79 heads of adult rabbits (20 heads doe and 20 heads buck of HyCole, 14 heads doe and 12 heads buck of HyLa, and 5 heads of doe and 8 heads buck of new zealand white). A complete randomized design with unbalanced data analysis was used for quantitative traits and descriptive analysis for qualitative traits. Phenotype characterization were done qualitative and quantitative traits. Qualitative characteristics of hair color variation of HyLa rabbit was different than other with 7.7% pointed on their white hair color, and hip type compact of HyCole, HyLa and new zealand white were 90%, 84.6% and 76.9% respectively. Quantitative characteristics of chest size (circumference, depth and width) of HyCole and HyLa rabbits were higher than new zealand white. HyCole and HyLa rabbits had high productivity, therefore they were suitable for broiler rabbit. Crossing of these rabbits with new zealand white rabbit have potential to develop broiler rabbits that adapted in tropical climate.
