研究旨在比较几种禾本科饲料作物的营养价值,选择谷子、燕麦、青贮玉米、饲用高粱和苏丹草等5种禾本科饲料作物,系统测试抽穗期主要营养成分,并对营养成分含量均值进行方差分析和综合评价。结果表明:供试的禾本科饲料作物间中性洗涤纤维含量均值差异不显著,其余营养成分含量均值差异极显著,经综合评价5种饲料作物的营养价值,表现最优的品种为谷子,其次是燕麦、青贮玉米、饲用高粱和苏丹草。
The aim of this study was to compare the nutritional value of several gramineous forage crops. Five gramineous forage crops such as millet, oats, silage corn, forage sorghum and sudangrass were selected to systematically test the main nutrient components at heading stage. The mean value of nutrient contents Analysis of variance and comprehensive evaluation. The results showed that there was no significant difference in the mean value of neutral detergent fiber between the gramineous forage crops tested and the average content of the other nutrients. The comprehensive evaluation of the nutritional value of the five forage crops showed that the best performing variety was millet, It is oats, silage corn, sorghum and sudangrass.
