In order to study the rational standard of protein nutrition in the diet for the growing rabbits, the test was carried out with 2 replicates. 21 testees were carefully selected from the crossbred rabbits aged from 70 to 120 days and then divided into 3 groups symmetrically, each of the 3 groups being the same in sex, weight and crossbred type. The test period lasted 45 days. The nutrition indexes were kept consistent for each group but the protein diet was made at 18%, 20% and 22% respectively. The results are as follows: The weight of tested rabbits in all the 3 groups registered an average increase of 115.1%, 116.6% and 117.4% separately. No apparent influence on the range of weight increase was observed when protein was increased by 2-4% in the diet. The difference of feed reward was not obvious. The cost of the high protein feed was 0.58 RMB yuan higher than that with 18% protein content and the protein feed is much more expensive than the energy feed. Therefore, the diet containing 18% protein would completely satisfy the need of growing rabbits ranging from weaning to 3 months of age
