集约化养殖场羊与兔粪尿产生量的监测

Study on the Amount of Manure and Urine Excreted by Sheep and Rabbits in Intensive Pasture

以集约化养羊场、养兔场为研究对象,监测了不同季节羊与兔的粪尿排泄量、粪尿养分含量、饲料养分摄入量等。结果表明,兔日平均粪便排泄量0.37 kg.只-1,年粪便排泄总量135.05 kg.只-1,粪便中氮、磷、钾和有机质平均质量含量分别为25.55、5.07、6.59和660.4 g.kg-1;羊日平均粪便排泄量1.09 kg.只-1,年排泄总量397.85 kg.只-1,粪便中氮、磷、钾以及有机质平均质量含量分别为19.89、4.90、11.79和649.1 g.kg-1。同一季节,同种动物磷的排泄量与摄入量比值高于氮、钾,同种动物养分排泄量与摄入量比值在不同季节也有差异。

The excretion amount,the nutrient content of sheep and rabbit fecaluria and the ingested amount of feed nutrient at four seasons were monitored in large scale sheep and rabbit farm.The results show that： the average excretion amount of rabbit fecaluria per day was 0.37 kg and the total excretion amount of rabbit fecaluria per year was 135.05 kg.The content of nitrogen,phosphorus,potassium and organic substance of rabbit manures was 25.55,5.07,6.59 and 660.4 g·kg^-1,respectively.The average excretion amount of sheep fecaluria per day was 1.09 kg and the total excretion amount of sheep fecaluria per year was 397.85 kg.The content of nitrogen,phosphorus,potassium and organic substance of sheep manures was 19.89,4.90,11.79 and 649.1 g·kg^-1,respectively.For homogeneity animal in same season,the ratio of phosphorus ingestion amount to excretion amount was higher than that of nitrogen and potassium.
