Analysis Of The Current Situation Of Coccidiosis Medicine Questions And It's Controlling Strategies

It is important that the coccidiosis controlling approaches was applied or developed because the parisasitic disease exists widespread with a dramatic economic losses.Up to now, the mainly strategy for controling coccidiosis is still depending on anticoccidial drugs in feed-processing plant. The anticoccidial drugs are used as feed additives for the purpose of coccidiosis prevention. The development and use of these drugs provide a significant increase in the performance of broilers. But we should notice that the most of broiler producers know very few about anticoccidial drugs. There are still a lot of problem regarding anticoccidials for coccidiosis control. It is very important to design a strategic programmes ensuring the function of drugs. Anticoccidial programmes should be designed to based on the epidemiology of coccidiosis, the prevalence of resistant strains and the strengths and weaknesses of different anticoccidials.Resistance of Eimeria spp. against anticoccidial drugs is in-creasing because of unsuitable us the drug for a long time. Now, it is very difficulty to control coccidiosis by anticoccidial drugs. Investigation on resistance-drugs showed that most of strains from field isolates appeared resistance to anticoccidial-drugs, even to "cross-resistance" or resistance for most of anticoccidials.At this moment, few products are under active development. Because of expensive cost, no other new anticoccidial with a truly different mode of action seems likely to come on to the market in the near future. The one way to control the disease this is to design strategic programs to create new life of old products or combine with different products. But it should relay on field monitoring and sensitivity testing. On the other hand, as a "green step", vaccines have proved to be effective tools for the control of coccidiosis. The strategy of combine with vaccine and drugs for coccidiosis control has been approved by a lot of poultry disease specialist.Along with development of molecular biology, we should have a better understand to the effective mechanism of anticoccidials. It will provide theoretical foundation for selecting and rational using anticoccidial drugs, and will be contributed to improve technology of coccidiosis prevention.
