Abstract: 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.
