Advances on the Performance of Veterinary Antibiotics in Soil

Veterinary antibiotics are extensively used as prophylactics,theraputical medicines,growth promotors and additives in livestock production.The antibiotics are excreted mostly unmetabolized in feces and urine after administration to livestock.After entering into the soil,the residues undergo some processes of sorption,transportation,degradation and so on.These behaviors will determine the potential effects of antibiotics in the soil such as inducing antibiotic-resistance genes,disrupting indigenous microbial populations or contaminating groundwater,and even surface water.Based on the recent researches developments in the recent years,a summary is presented on the performance of veterinary antibiotics in the soil and directions of future research are recommended as well.
