Abstract

We examined the forage quality to provide the basic information for the utilization of blackberry by-products (leaf and stem) among thirty-five mutant lines derived from gamma-ray. The leaves had higher crude protein (CP) contents than stems. In addition, the leaves showed broad ranges of variation in crude fat, crude fiber and crude ash. The overall forage quality of the stems were similar to those of the original variety. The mean of neutral detergent fiber (NDF) content of leaves and stems in mutant lines were 25.88% and 58.98%, respectively. Also, the mean of acid detergent fiber (ADF) content of leaves and stems in mutant lines were 15.43% and 49.27%, respectively. Forage quality grades of all blackberry leaf were special quality class. However, the blackberry stem ranked $1^{st}$ to $5^{th}$ in quality class. The stem diameter was negatively ($P{\leq}0.05$) correlated with the moisture and crude protein. Also, the fruit length was highly negatively ($P{\leq}0.01$) correlated with the RFV (relative feed value) in blackberry leaf. The one hundred fruit weight was highly negatively ($P{\leq}0.01$) correlated with the crude ash. Based on these results, the by-products of blackberry could provide high quality forage for feeding of live stock.
