山地夏季人工草场山羊放牧适口性研究

Study on the Forage and Grass Palatability to Goats in Artificial Hilly Grass-land in Summer Season

在福州北峰的夏季人工草场,通过划区轮牧试验对山羊的适口性进行了研究。试验结果表明,在对杂交狼尾草、甘薯、百喜草等7种牧草进行的适口性评价,甘薯对山羊的适口性最好,表现为嗜食;对杂交狼尾草表现为喜食;羽叶决明、南非马唐、俯仰马唐对山羊的适口性较差。同样,山羊对百喜草、印度豇豆等牧草的不同生育期,其适口性系数也发生变化。

an experiment on the forage grass palatability to goats in the rotation-grazing plots of artificial grass-land in summer season in Fuzhou Beifeng hilly area was conducted. The experimental results showed that, among 7 species forages or grasses tested, the best palatability to goats was leaves of sweet potato, second one was Pennisetum × P. purpureum CV. 23A× 51, the palatability of Chamaecrasta nictitans, Digitaria smutsii cv. Premier and Digitaria decumbens were worse. The palatability coefficients of Paspalum notatum cv Flugge and Vigna sinensis Sari Vat were varied with the change of growing seasons.
