摘要
为了探索豫西地区羊常用的3种粗饲料(紫花苜蓿、大力士、黄豆)的营养成分及不同干燥方法(自然晒干和实验室烘箱65℃、105℃烘干)对其茎、叶营养成分的影响,试验采用概略养分分析法分别对3种粗饲料进行营养成分分析。结果表明:3种粗饲料的品质以紫花苜蓿最优,大力士最差;在不同的干燥条件下粗蛋白(CP)的含量实验室烘箱105℃烘干>实验室烘箱65℃烘干>自然晒干;粗脂肪(EE)含量受干燥温度的影响较大,随温度的升高其含量呈升高的趋势;粗纤维(CF)含量以自然晒干最高。
In this paper, the authors explore the nutrient of stems and leaves of three common forages ( alfalfa, soybeans, hercules, ) in western Henan province and illustrate the influence of different drying methods( suneured, 65 ℃ drying in the lab and natural dried, suncured, 105℃ drying in the lab)on stems and leaves with the method of Feed Proximate Analysis. The results show that: alfalfa has the best quality, hercules is the worst among the three kinds of roughage. The content of crude protein(CP) is richest under drying way of being suncured 105 ℃ in the lab, and the poorest condition is the natural dried ; crude fat (EE) content is greatly influenced by drying temperatures which is increasing with the temperature rising; the content of crude fiber (CF) is the highest under the condition of the natural dried.
