羊是反刍动物,对饲料咀嚼很细,加之饮水少,故粪中水分含量少而肥分量高。据测定,羊粪含氮0.65％、磷0.50％、钾0.25％、有机质31.4％。羊粪比马粪发热量低,而比牛粪发热量高,发酵速度较快,群众把它视为精肥。羊尿的养分含量也很高,含氮1.68％、磷0.03％、钾2.1％、有机质8.3％。羊粪尿的养分含量高于牛、马粪尿的养分含量。每只羊一昼夜排泄粪尿量为4 Sheep is a ruminant, very fine chewing feed, coupled with less drinking water, so the manure in the water content less fat and high. It was determined that sheep manure 0.65% nitrogen, phosphorus 0.50%, potassium 0.25%, organic matter 31.4%. Sheep manure than horse manure low calorie, but higher than cow manure heat, fermentation speed, the masses treat it as fine fat. The nutrient content of sheep urine is also very high, containing 1.68% nitrogen, 0.03% phosphorus, 2.1% potassium and 8.3% organic matter. The nutrient content of sheep manure urine is higher than the nutrient content of cattle and horse manure. Diurnal excretion of urine per day and night for four sheep
