一 拌料給藥的藥物

拌ban料liao給gei藥yao的de藥yao物wu一yi般ban是shi難nan溶rong於yu水shui或huo不bu溶rong於yu水shui的de藥yao物wu。此ci外wai

，如ru一yi般ban的de抗kang球qiu蟲chong藥yao及ji抗kang組zu織zhi滴di蟲chong藥yao，隻zhi有you在zai一yi定ding時shi間jian內nei連lian續xu使shi用yong才cai有you效xiao，因yin此ci多duo采cai用yong拌ban料liao給gei藥yao。抗kang生sheng素su用yong於yu控kong製zhi某mou些xie傳chuan染ran病bing時shi，也ye可ke混hun於yu飼si料liao中zhong給gei藥yao。

二 準確掌握混料濃度

進行混料給藥時應按照拌料給藥濃度，準確、認ren真zhen計ji算suan所suo用yong藥yao物wu的de劑ji量liang。若ruo按an禽qin隻zhi體ti重zhong給gei藥yao，應ying嚴yan格ge按an照zhao禽qin隻zhi體ti重zhong，計ji算suan總zong體ti重zhong，再zai按an照zhao要yao求qiu把ba藥yao物wu拌ban進jin料liao內nei。藥yao物wu的de用yong量liang要yao準zhun確que稱cheng量liang

，切qie不bu可ke估gu計ji大da約yue
，以yi免mian造zao成cheng藥yao量liang過guo小xiao起qi不bu到dao作zuo用yong

，或huo過guo大da引yin起qi中zhong毒du等deng不bu良liang反fan應ying。混hun於yu飼si料liao中zhong的de藥yao物wu濃nong度du以yi百bai萬wan分fen之zhi（ppm）表示
，例如百萬分之125（125ppm），就是每千克飼料加入藥物125毫克。

三 確保用藥混合均勻

為了使所有禽隻都能吃到大致相等的藥物，必須把藥物和飼料混合均勻。拌藥時堅持做到：congxiaoduidaodadui，fanfuduocijiaoban，bimiangebieqinzhizhongdudefasheng。jiarusiliaozhongdeyaoliangyuexiao，yueyaoxianyongshaoliangsiliaohunyun。kailiaoshiyaobaozhengyouchongzudeliaowei，rangsuoyouqinzhinengtongshicaishi，congershimeizhiqindouchidaoheshideyaoliang。

四 用藥後密切注意有無不良反應

有you些xie藥yao物wu混hun入ru飼si料liao後hou，可ke與yu飼si料liao中zhong的de某mou些xie成cheng分fen發fa生sheng拮jie抗kang反fan應ying，這zhe時shi應ying密mi切qie注zhu意yi不bu良liang作zuo用yong。如ru飼si料liao中zhong長chang期qi混hun合he磺huang胺an類lei藥yao物wu
，就jiu易yi引yin起qi維wei生sheng素suB和維生素K的缺乏，這時應適當補充這些維生素。另外還要注意中毒等反應
，發現問題及時加以補救。
