在日常飼養管理中，用藥物預防的兔病主要是球蟲病。經常出現用了抗球蟲藥，還會發生球蟲病。原因主要有以下幾點。
In the daily feeding and management, use drug prevention of rabbit disease is mainly coccidiosis. Often used coccidiostats, coccidiosis will happen. The main reasons are the following.
1、假藥  由于獸藥市場無序競爭，隨著不斷下降，質量也不容樂觀，加上一些不法商人利欲熏心，假藥充斥市場的現象大家都清楚。假藥主要是有效藥物含量不足，按正常藥量添加起不到預防球蟲病的作用。
1, because of the disorderly competition of counterfeit veterinary drug market, with prices falling, quality is not optimistic, some unscrupulous traders be reckless with greed plus, counterfeit market is full of clear to everyone. The main content of counterfeit drugs is an effective drug problems, according to the normal dosage added to prevent coccidiosis effect.

2、預防程序  有人認為兔球蟲病多發生于氣溫高的霉雨季節，對于冬天或氣溫較低的地區，球蟲病發生較少，故不用藥物預防球蟲病。或者是用一段時間停一段時間，因不能維持足夠的藥物有效濃度，導致兔發生球蟲病。
2, some people think that the rabbit coccidiosis prevention programs occur in high temperature in winter or rainy season, the area of low temperature, coccidiosis occurs less, so no drugs to prevent coccidiosis. Or use a period of time to stop for a period of time, because cannot maintain effective drug concentration enough, lead to the occurrence of coccidiosis in rabbits.
3、添加量  用藥物控制球蟲病，兔體內必須要達到一定的有效藥物濃度，飼料中添加藥物是常用的方法。由于特殊情況，飼料中的藥物濃度或配藥比例是正常的，但由于天氣炎熱，兔的采集量下降，導致兔得不到足夠的藥物；或者是在一些地方養兔既喂料又喂草，每天兔子食入的飼料量并不多，藥物自然也不足。一些病兔，同樣由于采集量下降，發生球蟲病。
Drugs used to control coccidiosis, adding amount of 3 rabbits, must want to achieve an effective concentration, adding medicine in feed is a commonly used method. Due to special circumstances, the drug concentration in feed or dispensing proportion is normal, but because of the hot weather, the acquisition amount rabbits decreased, resulting in rabbits do not have enough drugs; or is in some places rabbit both feed and feed grass, feed the rabbit food into every day is not much, the drug also insufficient natural. Some of the same rabbit disease, due to the decline in the volume of collection, happening coccidiosis.
4、拌料不勻  一些抗球蟲藥用量極低，如地克珠利，正常添加量僅為1ppm，相當于1噸飼料中加1克原藥，如果沒有特定的設備，是無法混合均勻的，當然會影響預防效果。一些較大規模的兔場為降低成本，買原料藥直接加在飼料中做成顆粒料喂兔，導致一部分兔發病。
4, the mixing uneven some anticoccidial drug usage is extremely low, such as the diclazuril, normal addition amount is only 1ppm, equivalent to 1 tons of feed plus 1 grams of raw materials, if no specific equipment, cannot be mixed evenly, certainly will influence the effect of prevention. Some of the larger scale rabbit farm in order to reduce the cost of buying raw material medicine is directly added into rabbits fed pellets in the feed, resulting in a rabbit disease.
