| 中文摘要 |
| 饲料胶原蛋白粉的LD50>10g/kg,属实际无毒级;蓄积系数K>5.28,属弱蓄积性;Ames试验不论加S-9混合液与否,致突变作用结果为阴性;微核试验剂量高达5g/kg仍为阴性;精子畸形试验剂量高达5g/kg亦呈阴性。 |
| 英文摘要 |
| he feed collage protein powder has a LD50> 10g/kg, and can be assessed to be in an actually nontoxic grade. It has an accumulative coefficient K>5.28,which is considered to be weakly accumulative. The Ames test result of mutugenesis is negative, either with or without adding S-9 mixed liquid. The micronucleus test and spermatozoon malformation test also showed a negative reaction when dosage exceeded 5g/kg. |
