| Abstract: |
| In order to explore the characteristics of heavy metals and antibiotics in manure from large-scale meat duck production in Hebei Province, heavy metals in feed and manure of eight large-scale meat duck farms were monitored in August(summer)and October(autumn)2019, respectively. In April 2020, the heavy metals and antibiotics in manure samples were investigated from 17 large-scale duck farms with different breeding methods(4 breeding ground; 5 litter breeding; and 8 rack breeding). The results showed that the heavy metals in meat duck feed and manure were mainly Cu and Zn, and the content showed Zn > Cu > Cr > Pb > As > Cd. There was a highly significant positive correlation between Zn in feed and manure(P<0.01). The Cu, Zn, and Cr levels in manure exceeded the German Compost Limit Standard. Under different breeding modes, the antibiotics in the meat duck manure showed tetracyclines > quinolones, whereas sulfa and macrolides were not detected. The concentration of antibiotics in the manure showed ground breeding > rack breeding > litter breeding. Studies have shown that litter farming is a mode of meat duck farming that emits less environmental pollutants. |
