The effect of the level and the particle size of fiber on the availability of protein from shorts was studied. On a 10% protein diet, the rate of growth and PER tended to be somewhat higher in rats fed ground shorts (70 mesh; fiber about 10%) and was much higher in those fed wheat protein concentrate (70 mesh; fiber about 3%) as compared to coarse shorts (15 mesh; fiber about 10%). Also, despite somewhat low lysine intake (0.83 vs. 0.88 g.), more nitrogen was retained by rats fed wheat protein concentrate than coarse shorts (116 vs. 100%). Between the coarse and ground shorts, rats fed ground shorts also retained more nitrogen (109 vs. 100%). Protein digestibility of the two shorts did not differ but it was significantly higher for wheat protein concentrate (83 vs. 71%). The pattern of plasma-free amino acids tended to reflect the quality of ingested protein more closely for wheat protein concentrate and ground shorts than for coarse shorts.
