不同干燥法对豫西地区羊粗饲料营养成分的影响

Analysis on forage nutrients of sheep by different drying methods in western Henan province

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.
