基于摄入养分含量预测猪新鲜粪便肥料成分含量的试验研究

his experiment is to build mathematical model in order to estimate fertilizer value of raw swine slurries based on nutrients intake. Data of nutrient contents in diets and in slurries were obtain by feeding experiment and analyzed. One-way ANOVA analytical results of this paper show that the effect of different diets on the content of total nitrogen in pig feces, urine and manures is significantly different; the effect of different diets on the content of potassium in pig urine and manures is significantly different; the effect of different diets on the content of phosphorus and ammoniacal nitrogen in pig slurries is not significantly different; the effect of different diets on the percent of phosphorus in pig feces is significantly different. Linear regression analytical results show that crude protein intake can be evaluated for estimating the content of total nitrogen in pig feces, in pig urine and in pig manures; potassium intake can be evaluated for estimating the content of pota
