Abstract & Objectives] This study was conducted on the effects of veterinary antibiotics on pasture growth. & Methods] With alfalfa (Medicago sativa L. ) as an experimental material and Oxytetracycline, Chlortetracycline and enrofloxacin as experimental contaminants, the effects of the three veterinary antibiotics on the germination percentage, germination energy, germination index and vigor index of alfalfa seeds and on the plant height and root length of alfalfa seedlings were study at the concentration gradient of 50, 100, 150,200 and 250 mg/L, respectively. & Results] The Oxytetracycline treatments had no significant effect on the germination percentage of alfalfa seeds, but promoted is germination index. According to research, these antibiotics cannot be completely absorbed by animals, of which 40% -90% will be excreted in the form of feces, which will cause the unprocessed manure to carry residual antibiotics into the ecological environment to cause environmental pollution &1 3]. The residual veterinary antibiotics in the soil directly affect the quality of seed germination and seedling growth. [...]it is important to study the effects of veterinary antibiotics on the seed germination and seedling growth of forage grass. Results and Analysis Effects of Oxytetracycline treatment solutions on seed germination and seedling growth of alfalfa It can be seen from Table 1 that compared with te control group, the Oxytetracycline treatments were not significantly diferent in the germination percentage of aialfa seeds, and promoted the germination index to diferent degrees, with the strongest promoting effect at the Oxytetracycline concentration of 250 mg/L.
