Results showed that there were no significant difference in the contents of ammonia and urea in blood between the controls and tests. Essential amino acid indexes in both groups were 93.80 and 96.48 respectively; chemical scores were 45.27 and 49.84 respectively; methionine,lysine and arginine were all limited amino acids in the plasma and the contents of leucine in controls and tests were much… CONTINUE READING
