ABSTRACT
In the present study, an amino acid mixture had been prepared from whole swine blood by acid hydrolysis, ion-exchange separation and adequate supplementation of L-Trp, L-Met, and L-Ile. The content of essential amino acid, chemical score and essential amino acid index of the product were 49.33, 63.77, and 92.38% respectively and its essential amino acid pattern was closely similar to casein or whole egg protein with sulfur-containing amino acid as its first limiting amino acid. In the rat growth experiment, its nutritional value had been proved to be comparable with casein and better than swine blood powder itself in terms of weight gain, PER, and NPR. Therefore, this amino acid mixture can be considered as an ideal food additive and nitrogen source for elemental diet and this is an important way in the utilization of swine blood.
