摘要
针对富宁县的饲草资源,开展了桂牧1号杂交象草、纳罗克非洲狗尾草、曲辰9号玉米、宽叶雀稗、构树、银合欢6种饲用植物鲜草和青贮试验研究。结果表明:富宁县具有丰富而优良的饲草资源,曲辰9号玉米、桂牧1号杂交象草、构树、银合欢、纳罗克非洲狗尾草、宽叶雀稗均属于优良饲草。曲辰9号玉米、桂牧1号杂交象草、构树适口性均较好,家畜在50min采食率均达100%,且饲用价值较高,其中曲辰9号玉米可溶性碳水化合物含量较高,构树、银合欢粗蛋白、粗脂肪含量较高。非洲狗尾草、宽叶雀稗由于利用时间晚导致粗纤维较高,如提早利用可提高其饲用价值;青贮是提高饲草饲用价值的重要途径和方法。6种饲草青贮后营养成分均不同程度的改善,构树粗脂肪含量增加显著,非洲狗尾草、宽叶雀稗、桂牧1号杂交象草青贮后NDF、ADF含量降低,银合欢粗蛋白含量增加,曲辰9号玉米粗蛋白、粗脂肪含量增加;富宁县6种供试饲草青贮后适口性显著提升,家畜采食率均达100%,且采食时间不同程度缩短;6种饲草青贮后饲料相对值均有所增加,构树的饲料相对值从141.48%显著增加到211.19%,银合欢从89.23%显著增加到113.40%。桂牧1号杂交象草、非洲狗尾草、宽叶雀稗均增加10%左右。
Aiming at the forage resources in Funing County,we carried out the fresh grass and silage experiment of six forage plants such as T1.Pennisetum americanum×P.purpureum×P.purpu-reum cv.Guimu No.1,T2.Setaria sphacelata cv.Narok,T3.Zea mays,L.T4.Paspalum wettsteinii,T5.Broussonetia papyrifera,T6.Leucaena leucocephala.The results showed that Funing County had abundant and excellent forage grass resources.Corn No.9 Quchen,Hybrid Elephant Grass No.1 Guimu,Broussonetia papyrifera,Leucaena leucocephala,Setaria narok,Paspalum latifolia were all excellent forage grasses.Quchen 9 corn,Guimu 1 hybrid elephant grass,and Broussonetia papyrifera had good palatability.The feed intake rate of livestock reached 100%at 50 min,and the feed value was high.Among them,the soluble carbohydrate content of Quchen 9 corn was Higher,Broussonetia papyrifera,Leucaena leucocephala crude protein,crude fat content was higher.African Setaria and Paspalum vulgaris had higher crude fiber due to the late utilization time.Early utilization cound increase their feeding value.Ensilage was an important way and method to improve the feeding value of forage grass.The nutritional components of the six forage grass silages were improved to varying degrees,and the crude fat content of Broussonetia papyrifera increased significantly.After the silage of African Setaria,Paspalum vulgaris and Guimu No.1 hybrid elephant grass,the content of NDF and ADF decreased,and the crude protein content of Leucaena leucocephala.Increase,the crude protein and crude fat content of Quchen 9 corn increased;the palatability of 6 kinds of test forages in Funing County increased significantly after silage,the feed intake rate of livestock reached 100%,and the feeding time was shortened to varying degrees;After grass silage,the relative value of feed increased,the relative value of feed of Broussonetia papyrifera increased significantly from 141.48%to 211.19%,and Leucaena leucocephala increased significantly from 89.23%to 113.40%.Guimu No.1 hybrid elephant grass,African foxtail gra
