鸡得了球虫病,就不吃食,常泻血、泻水,鸡群的发病率在60%左右,死亡率达35%以上。现用的抗球虫病药剂一氨(口丙)啉,系人工合成的,防治效果虽较好,但易产生抗药虫株。因此,养鸡生产单位迫切要求科研部门能提供新的高效治虫药剂,以控制因球虫病所造成的损失。上海市农科院畜牧兽医研究所于1982～1984年应用国产抗生素821-2,对2万多羽鸡进行了舍试、田间试验,防治效果高达99.6%,与国产氨(口丙)啉的防治效果基本一致。最近通过技术鉴定并列为科研成果。有关专家认为,抗
Chicken got coccidiosis, do not eat, often spilled blood, diarrhea, the incidence of flocks in about 60%, the mortality rate of 35% or more. The current anti-coccidiosis agent ammonia (a propylene), Department of synthetic, the control effect is good, but easy to produce resistant strains. Therefore, chicken production units urgently require scientific research departments to provide new high-efficiency pest control agents to control coccidiosis caused by the loss. Shanghai Academy of Agricultural Sciences Institute of Animal Husbandry and Veterinary Medicine from 1982 to 1984 using domestic antibiotics 821-2, more than 20,000 chickens were tested, field trials, prevention and control of up to 99.6%, with the domestic ammonia Control effect is basically the same. Recently passed the technical appraisal and listed as scientific research achievements. Experts believe that anti-
