        Biological availability of proteins in oil seed meals such as soybean meal, rapeseed meal and perilla meal and in casein was evaluated in young growing chicks. One week of age, S.C.W. Leghorn male chicks were fed diets added with each source of protein singly up to a level of 13% protein for 10 days. Among chicks fed diets containing soybean meals from three different domestic processors, no significant differences were observed in feed intake, body weight gain, feed efficiency, NPU, PER or NPR values. Nitrogen availability of the meal imported from Brazil appeared inferior, without significance, to that of the meals domestically processed of which raw materials were originated from the U.S, Birds allowed diets containing domestically processed rapeseed meal whose raw material was from Canada, consumed 23% more and showed better feed efficiency as well as better PER value than those fed the meal imported from Pakistan (p $lt; 0.05). Perilla meal tended to lower feed efficiency and nitrogen availability compared to the other meals. Diets containing casein resulted in vary poor feed efficiency, weight gain and nitrogen availability compared to those of the diets containing soybean meal (p $lt; 0.05). It could be a reflection of the seriousness of lysine-arginine antagonism of the casein protein in young chicks. NPU values of the soybean meal, rapeseed meal, perilla meal and casein were in the ranges of 55-67, 57-58, 52 and 32%, respectively.
