| 摘 要： | 本文分析测定了我省不同类型滩羊产区混合牧草5个样品和主要牧草17种共34个样品的化学成分。结果表明:典型产区牧草的蛋白质和灰分含量均较对照区高,但粗纤维偏低。典型产区混合牧草灰分含量较对照区高1.4倍,较过渡产区高4倍,可消化有机物较对照区高9.8～20%,较过渡产区高21.6～30.3%。

Studies on Tan Sheep Ecology and Methods of Selection. The Third Report on Determination of Chemical Compositions in the Mixed Herbage and Main Species of Herbages in Various Tan Sheep Area in Gansu |

| Abstract: | Accrding to the grade of Tan Sheep fur, Jingtai, Gaolan and Yuzhong counties were taken as the typical, general and transitional area of Tan Sheep respectively and Wuwei county as the control area. 5 samples of mixed herbage and 34 samples of 17 main herbages were collected form various producing areas in the harvest year. Their chemical compositions were determined by means of the proximate analysis. The results of analysis showed that as compared with the control ares., the typical area was rich in crude protein and ash, but poor in crude cellulose. The content of ash of mixed herbage in the typical area is 1.4 times higher than that in the control area, and 4 times higher than that of transitional area. Its digestible organic material is 9.8—20 per cent higher than that of control, and 21.6—30.3 per cent higher than that of the transitional area. |
