Abstract
The press-defatted seeds of “Haze” (Rhus succedenea) were separated into the kernels and hulls, and their digestibilities by rats were determined.
The digestibility of the kernel powder was very low, namely: this for Organic matter Protein, Fat, Pentosan and Nitrogen free extract was found to be 15, 25, 95, 6, and 8%, respectively.
The main constituents of the kernel were cellulose and hemicellulose or pentosan (xylan), and only 22% of the hemicellulose were hydrolysed by taka-amylase.
The digestibility of the hull powder was generally higher than that of the kernel, namely: this for Organic matter, Glucide, Protein and Fat was found to be 45, 73, 12, and 47%, respectively.
The culculated available energy values were as follows: Kernel powder, 71 Cal. per 100g; and hull powder, 152 Cal.
