Endogenous Amino Acids in Budgerigars (Melopsittacus undulatus)

摘要

To determine the amount of endogenous amino acids in budgerigars (sekiselinko, Melopsittacus undulatus), as the first step of evaluating amino acid requirements, three experiments were conducted. In Experiments 1 and 2 , transit time of the feeds through the digestive tract in budgerigars was studied. The birds were given free access to a corn-based diet containing 50 /100 barium sulfate in Experiment 1, and Japanese millets (hie, Echinochloa utilis) with 0.5 ml of 50.100 barium sulfate solution in Experiment 2.
