Abstract: Two breeds of rabbit meat was analyzed : Kangda synthetic line and Hyplus synthetic line.The experiment measured nutrient component, cholesterol content and fatty acid composition of three ages (60, 70, 90d) .Results showed that Kangda synthetic line had a lower cholesterol content and a higher protein content than Hyplus synthetic line.While the amino acid and fatty acid content did not have difference.With the increase of age, protein content increased gradually.Rabbit at 70d had a lower fat and cholesterol content, but a higher P/S than other ages.
