摘要:
为明确生猪养殖氮磷污染物排放规律,以规模化生猪养殖场断奶仔猪为研究对象,结合种猪性能测定系统,对后备母猪全生育期内饲料和粪尿样品进行连续动态监测分析。结果表明,全生育期内饲料中氮素和磷素含量变化较小,且氮磷比为14.41±2.91。不同生育期间猪粪和猪尿样品氮磷污染物排放总量有显著性差异,其中总氮>硝态氮>铵态氮,且猪尿总氮排放量明显高于猪粪。全生育期内每头仔猪总氮和总磷排放量分别为2 059.78 g和28.71 g,分别占饲料氮磷投入总量的52.87%和10.37%。
Abstract:
To investigate the characterization of nitrogen and phosphorus pollutants during the complete period of gilts growth in a large-scale breeding farm, the characteristics of gilts feed, manure and urine were analyzed continuously during various gilts growth period combined with Nedap Velos livestock management system. The results showed that the concentration of different forms of nitrogen and phosphorus changed slightly in gilts feed during the whole growth period, and the N/P ratio was 14.41±2.91. Significant differences were found between nitrogen and phosphorus emission at different growth stages in pig manure and urine samples, which were total nitrogen (TN) > NO-3-N > NH+4-N. TN emission in the urine was extremely higher than that in the manure. TN and total phosphorus (TP) emission in the whole growth of a pig were 2 059.78 g and 28.71 g, respectively, which were 52.87% and 10.37% of the total nitrogen and phosphorus in the feed.
