四川阿坝县不同地区与不同海拔秋季牧草营养成分分析
Determination and analysis of fall forage nutrient contents at different altitudes and regions in Aba County,Sichuan Province
摘要
Abstract
The nutrient contents of autumn forages sampled from four pastures with different altitudes （3 400-3 800 m） at Aba County were determined separately. The results showed that the average con- tents of crude protein （CP）, crude fat （EE）, crude fibre （CF）, acid detergent fiber （ADF）, neutral deter gent fiber （NDF）, ash （Ash）, calcium （Ca） and phosphorus （P） were 10. 30%, 2. 92%, 29. 24%, 35.47%, 57.21%, 6.86,% 0.71% and0.14%, respectively. The contents ofCP, EE, CF, ADF, NDF, Ash and Ca in forages from different pastures had no significant difference （P〉0.05）. However, the difference of P content in the forages among different pastures was significant （P〈0.05）. The contents of CP, EE, CF, ADF, NDF and Ash in the forages from different altitudes had no significant difference （P〉 0.05）. The contents of Ca and P were obviously different （P〈0.05） among different altitudes. The nutrient contents of autumn forages at Aba County are suitable for season grazing, but supplementary feeding is essential as well.关键词
