，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促cu進jin生sheng長chang及ji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。呋fu喃nan唑zuo酮tong（痢特靈）及酚噻嗪（驅蟲藥）難溶於水，必須混於飼料中給予。混於飼料中的藥物濃度以百萬分比 （ppm）表示，例如百萬分之125（125ppm），等於每噸飼料加入125克藥物
，或每公斤飼料加入藥物125毫克。

在應用混料給藥，應注意以下幾個問題：

1.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群qun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大da概gai估gu計ji，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。

2.確(que)保(bao)用(yong)藥(yao)混(hun)合(he)均(jun)勻(yun)。先(xian)把(ba)藥(yao)物(wu)和(he)少(shao)量(liang)飼(si)料(liao)混(hun)勻(yun)，然(ran)後(hou)將(jiang)它(ta)加(jia)入(ru)到(dao)大(da)批(pi)飼(si)料(liao)中(zhong)，繼(ji)續(xu)混(hun)合(he)均(jun)勻(yun)。加(jia)入(ru)飼(si)料(liao)中(zhong)的(de)藥(yao)量(liang)越(yue)小(xiao)，越(yue)是(shi)要(yao)注(zhu)意(yi)先(xian)用(yong)少(shao)量(liang)飼(si)料(liao)混(hun)勻(yun)。直(zhi)接(jie)將(jiang)藥(yao)加(jia)入(ru)大(da)批(pi)飼(si)料(liao)中(zhong)是(shi)很(hen)難(nan)混(hun)勻(yun)的(de)。對(dui)於(yu)容(rong)易(yi)引(yin)起(qi)藥(yao)物(wu)中(zhong)毒(du)或(huo)副(fu)作(zuo)用(yong)大(da)的(de)藥(yao)物(wu)

飲水給藥

1.藥前停水，保證藥效。為保證禽隻飲入適量的藥物
，多在用藥前，讓整個禽群停止飲水一段時間，一般寒冷季節停水4~5小時，氣溫較高季節停水2~3小時
，然後換上加有藥物的飲水，讓禽隻在一定時間內充分喝到藥水。
