【摘要】：本研究对河南省12家规模化猪场饲料及粪便中氮磷、重金属及抗生素含量进行调查,采集断奶仔猪、保育猪和育肥猪3个阶段的饲料和粪便样品,测定样品中粗蛋白、总磷、部分重金属元素(锌、铜、砷)和抗生素(金霉素和喹乙醇)的含量,并进行相关性分析。结果表明:规模化猪场断奶仔猪饲料中粗蛋白、磷、铜、锌、砷、金霉素和喹乙醇平均含量分别为19.49%、0.60%、184.25 mg/kg、1853.33 mg/kg、4.79 mg/kg、3.50 mg/kg、22.95 mg/kg,保育猪饲料中上述各指标平均含量为18.26%、0.56%、174.00 mg/kg、719.17 mg/kg、7.55 mg/kg、7.00 mg/kg、24.04 mg/kg,肥育猪饲料中各指标平均含量为16.63%、0.47%、133.50 mg/kg、192.17 mg/kg、5.88 mg/kg、2.62 mg/kg、4.98 mg/kg;断奶仔猪粪便中粗蛋白、磷、铜、锌和砷平均含量分别为26.15%、2.57%、816.67 mg/kg、4 853.33 mg/kg、13.07 mg/kg,保育猪粪便中上述各指标平均含量分别为25.99%、2.89%、1 475.00 mg/kg、4 798.33 mg/kg、22.72 mg/kg,肥育猪粪便中各指标平均含量分别为21.64%、2.83%、948.33 mg/kg、1 730.00 mg/kg、41.21 mg/kg,所有猪粪便中均未检测出金霉素和喹乙醇。断奶仔猪和保育猪饲料中总磷含量与粪便中总磷含量呈显著正相关(P0.05),饲料中铜含量粪便中铜含量在断奶阶段呈显著正相关(P0.05)、在育肥阶段呈极显著正相关(P0.01);饲料中锌含量与粪便中锌含量在保育阶段达到了显著正相关(P0.05);饲料中砷含量与粪便中砷含量均呈正相关,但相关性均未达显著水平(P0.05)。
[Abstract]:The contents of nitrogen and phosphorus, heavy metals and antibiotics in feed and feces of 12 large scale pig farms in Henan Province were investigated. The feed and fecal samples of weaning piglets, conservation pigs and fattening pigs were collected, and the crude protein and total phosphorus in the samples were determined. The contents of some heavy metals (zinc, copper, arsenic) and antibiotics (chlortetracycline and quindoquindox) were analyzed. The results showed that the average contents of crude protein, phosphorus, copper, zinc, arsenic, chlortetracycline and quindoquindox in the feed of weaned piglets in large-scale pig farm were 19.490.6010 and 184.25 mg/kg,1853.33 mg/kg,4.79 mg/kg, respectively. 3.50 mg/kg,22.95 mg/kg, average content of above indexes in pig feed is 18.260.56g / L 174.00 mg/kg,719.17 mg/kg,7.55 mg/kg,7.00 mg/kg,24.04 mg/kg, The average content of each index in the feed of fattening pig is 16.630.470.470.133.50 mg/kg,192.17 mg/kg,5.88 mg/kg,2.62 mg/kg,4.98 mg/kg;. The average contents of crude protein, phosphorus, copper, zinc and arsenic in feces of weaned piglets were 26.15 and 2.57 mg/kg,4 / 853.33 mg/kg,13.07 mg/kg, respectively. The average contents of the above indexes in pig feces were 21.64 and 2.83, respectively. The average contents of the above indexes were 25.99 and 2.89 respectively, and the average contents of the above indexes were 21.64 and 2.83 in the feces of 1 475.00 mg/kg,4 and 798.33 mg/kg,22.72 mg/kg, fattened pigs, respectively. No chlortetracycline and quindoquindox were detected in 948.33 mg/kg,1 730.00 mg/kg,41.21 mg/kg, pig feces. There was a significant positive correlation between total phosphorus content and fecal total phosphorus content in weaning piglets and nursery pigs (P0.05), and copper content in feces in weaning stage (P0.05). Significant positive correlation was found in the fattening stage (P0.01). There was a significant positive correlation between zinc content in feed and zinc content in feces in conservation stage (P0.05), and there was a positive correlation between arsenic content in feed and arsenic content in feces, but the correlation was not significant (P0.05).
