MG-related problems in the poultry industry
In the period after infection, the organism is present in the respiratory tissues in high levels and is shed into the environment and eggs. The infection persists in the flock for a long time. However, the organism is very fragile and can live outside the chicken for only a few days and is easily killed by disinfection.
Although biosecurity measures are very important, use of antibiotics and vaccines are also among the strategies which may reduce the adverse affects of MG infection in commercial farms.
I. Depending on your workstation (broilers, broiler breeders, commercial layers), how is the magnitude of MG-related problems in your farm?
II. Do you think that use of antibiotics is still the most practical way to manage this infection?
III. How promising do you see preventive effects of vaccination?
VI. How about using a combination of antibiotics and vaccines?

MG is an chronic infestation. There are combination of factors which trigger and sustain the infection to remain viable and spread from one flock to the next. Some of the causes are : 1. Poor biosecurity measures 2. High dust levels 3.Secondary infections like E.Coli, IBD, Infectious Coryza 4.Over crowding. 5.Close proximity to other farms 6.Multiple age groups. Tackle these problems with proper balanced diet, MG bacterins and medication will reduce the problem and in the long run control the problem at a site.
it depends on history & severity . in breeders can be controlled by vaccination . in broilers - give first 3 days Pulmotil ( ELANCO product )@ 3.5 ml / 1000 birds & repeat at 21 & 22 days @ 30 ml / 1000 birds , in addition support thr. feed with Tylosine phosphate ( 10% )@ 1000gms / ton & ctc ( 15% ) @ 1000 gms./ ton of feed regularily . for layers by using Tylosine tartrate (raw ) @ 8 gms/1000 birds for first 3 days & support it with Tylosine phosphate & ctc thr. feed regularily .
firstly we all know the economic importanc of MG as one of the costlist disease problem in poultry indusry,causing CRD and mortality from5-30% in broiler, 1-2%monthly in layers with egg losses 15/egg/hen and 5%decrease in hatchability rate with late embryonic death.My PH.D was in evaluation of mycoplasma vaccines in poultry farms and my conclusion was using of bactern with antibiotic treatment when infection is diagnosed,this will decrease the shedding of mycoplasma to day old chicks. yours dr: eid soliman researcher,mycoplasma dep. animal health research institute cairo Egypt
