[Effect of gum guar in the diet on the utilization of 14C-labeled protein and protein hydrolysates in young rats].

Beginning on the 25th day of life and for 2 weeks therafter Sprague-Dawley rats were fed a casein diet containing 10% of gum guar. The animals were given. 14C algal protein or 14C algal protein hydrolysate by stomach tube and the radioactivity in some tissues and tissue proteins was determined 3 h after the application. Radioactivity in blood and in respiratory CO2 was measured up to 3 h and 6 h, respectively, after the application. The results indicate no effect of gum guar on the utilization of the protein or of the amino acids of the protein hydrolysate.
