猪粪尿中N、P、Cu、Zn排放量的测定与分析
Measurement and Analysis on N.P, Cu and Zn Excretion in Pig Faeces and Urine
摘要
Abstract
In the study, 5 piglets of (20±l. 0) kg, 5 growers of (70±2. 0) kg and 5 sows (with two-month pregnancy) were used to test the pollutant (N, P, Cu and Zn) producing coefficients of pigs at three production stages in four seasons and pollutants produced daily by pigs at different stages. The result showed that the pollutant producing coefficients in four seasons and produced daily pollutants were all different. The N producing coefficient of piglets in summer was very significantly (P<0. 01) higher than that of other seasons, whereas the pollutant producing coefficients of P and Cu were not significantly affected by seasons (P>0. 05). As for the growers and sows, the pollutant producing coefficients of P, Cu and Zn were significantly affected by seasons (P<0. 01), and they had almost the same change patterns in the four seasons. Pollutants daily produced by pigs at different stages were different, and sows produced very significantly more N, P, Cu and Zn than growers(P<0. Odand the growers produced very significantly more Cu and Zn than piglets(P<0. 01). It showed the daily pollutant production at different stages and its coefficient in four seasons are different. Therefore, we should research balanced feed formula according to the different seasons and pig stages, to both satisfy the nutrition of pigs and reduce maximally the pollutants produced by them.关键词
