Effects of feeding Phalaris tuberose cv.Wenning on black goat

The Weining Buld Reed Canary fresh grass (Phalaris tuberosa cv. Weining) at the different growth period was used to feed the black goats with different methods to assess the feeding effectiveness by using the palatability, feed consumption and economic benefits. The results of this study showed that the fresh P.tuberose herbage at the different growth stages showed a different effectiveness, in which the palatability were the best when the P.tuberose was period from the tiller stage to heading stage with the plant height of 50-120 cm, and it was the worst when P.tuberose was flowering stage. Different feeding approaches and different hungry degrees showed a different the palatability and feed intake, indicating that the cuttingfresh herbages showed the best feeding effectiveness when the black goats were in hunger and in a half full; and the combination of cuttingfresh herbage and 0.5% salt water showed the best feeding effectiveness when the black goats were in a full eight or nine. The addition of 8.8% green fodder had the better economic benefits than the only the green fodder, which increased the 26.5 CNY per black goat.
