Dear Dr. Saravanan I think the answer refers to your situation. as long as there is Mg and Ms in the other sectors of poultry industry such as Layers or other neighbering breeders or broilers i Believe use of vaccines is necessary to protect the flcoks from Mg and Ms infection. The vaccines Mg Ts-11 and MSH are protective when applied correctly therefore the next round of usage is depends on Risk of exposure. It is also important to note that the vaccination of flocks is some sort of insurance for the flcoks when it is combined with a good and solid biosecurity. in my oponion, continuation of vaccination is highly related to level of infection with Mg and Ms in yourpoultry industry. if the risk of becoming positive with Mg and Ms is high i think vaccination is powerful tools to protect your flocks. Hope this could help Regards rfadavi@yahoo.com
I think you should check your water source. The water should be purified properly. You can also use acidifier. Finally you should vaccinate the birds.
Dear : I suggest to do the follwing : !- In the feed : you can use Lincospectin primex ( 44:44 ) lincomycin -spectinomycin as feed additives the dosage should be 2 kg/MT from the finished product or you can get raw material and mix it to get the rate the duration time should be not less than 5 days also you have another choices like kitasamycin 20% and you can after that use the prevention way every 21 days also we can increase the dosage of toxin binders up to the double 2- in drinking water : you can sue tilmycosin 25% in the rate of 100 ml/200 L and i prefer to make synergistic by adding fosomycin 20% at the same rate the duration also not less than 5 days 3- the chicks : I suggest to inject with lincospectin injection in the hatchery the dosage 0,1-0,2 ml/chick only one time and one day old With all my best wishes Dr yahia ,A.
