Nutrient value of wild fodder species and the implications for improving the diet of mithun (Bos frontalis) in Dulongjiang area, Yunnan Province, China by Geng, Y., Ranjitkar, S., Yan, Q., He, Z., Su, B., Gao, S., Niu, J., Bu, D.P., Xu, J.C.

“…There was a significant difference between 21 species on their in vitro digestibility and the most highly digestible fodder species was Elatostema hookerianum. Linear model analysis on relationship between frequency of citation of 21 wild forage plants by local farmers and their nutrient composition showed that the frequency was significantly positively correlated with the nutritional value of the feed (R2 = 0.28, P < 0.05). …”
