Dear colleages and professionals.. This is a case of infectious coryza in a farm of Eastern Nepal. One flock with 3000 birds has recent outbreak of infectious coryza .The history shows no vaccinations done against this dz and the flock had an outbreak of the same disease two months ago. The flock was treated with sulpha and trimethoprim combinations during the period according to the owner. Please recommend the medication to put an end to this bacteria and stop the carriers in future outbreak along with lifting up the dropped production.The flock seems to have been administered sulpha drugs repeatedly, Is it suitable to use the same??
Dear all, recently I got a complaint from a layers farm at Jhapa that I have been observing for more than a year. The farm with three flocks (4500 each) at different ages has production range of 85-90% . A few days before the farmer complained that the egg size was fine but the egg weight is comparatively low. I made a visit of the farm to confirm the case, I found he was right, the egg size was fine along with the egg shell color and thickness there was a very low rejection percentage but the average weight of the ungraded egg was found to be between 52-53 gms for all the flocks. What could be the possible reason behind this and how can this issue be solved??
Is it mandatory to vaccinate broiler as per the schedule?
