玉米秸秆微贮营养价值的变化及对肉羊生长性能影响的研究

本试验将玉米秸秆进行微贮，检测了微贮后营养价值的变化及其对肉羊生长性能的影响。研究表明，玉米秸秆微贮后，湿润、具酒香味、质地柔软、适口性好，中性洗涤纤维（NDF）、干物质（DM）及酸性洗涤纤维（ADF）值显著下降，粗蛋白（CP）值显著升高。结果显示，微贮玉米秸秆后，营养价值得到有效的改善；玉米秸秆微贮后饲喂肉羊，试验组肉羊日增重较对照组增加21.76 %。

Study on the Change of Nutritional Value of Micro storage Corn Stalk and Its Effect on the Growth Performance of Mutton Sheep

In this experiment, corn stalks were micro stored. We examined the changes in nutritional value after micro storage and its effect on growth performance of mutton sheep. Studies have shown that after micro storage of corn stalks, it is moist, has wine aroma, soft texture and good palatability, the values of neutral detergent fiber (NDF), dry matter (DM) and acid detergent fiber (NDF) decreased significantly, and the crude protein (CP) value increased significantly. The nutritional value of corn stalks was effectively improved after micro storage. The mutton sheep were fed after micro storage of corn stalks, and the daily gain of the mutton sheep in the experimental group was 21.76% higher than that in the control group.
