Hi everyone, I have a farm with 20,000 laying hens which are 16 weeks of age. Two weeks ago, an outbreak of mycoplasma emerged with high mortality (70-80 birds per day) and now Salmonella has been confirmed by lab with a mortality of 200 birds per day. From your experience, which combination of antibiotic has given you the best results? Antibiogram is underway, but I must start medicating. Thank you
All proposed treatments give the result but I think with diagnosed infection by these pathogens combined therapy should last longer, at least 10 days, oxytetracycline, and up to 15 days. After the treatment, the flock shall regularly receives some of probiotics and hygiene watering and feeding must be seamlessly.
Salmonellosis in poultry becomes a problem when dealing with either gallinarum or pullorum specie, therefore it is advisable that you first of all identify the specie you may be dealing with. Salmonella gallinarum infection may frustrate your effort of treatment, because my experience showed that ENROFLOXACIN may not give you the desired effect. The only drug that may give you a satisfactory result is one of the PROHIBITED DRUGS (FURAZOLIDONE or CHLOROAMPHENICOL), which when you treat for atleast 10 days will stop the mortality.
En el caso de la crianza de pollos orgánicos, los pollitos BB deben provenir de reproductoras libres de Mycoplasma gallisepticum y suministrales un alimento de inicio con 23 % de proteína y energía metabolizable de 3.20 MCal/kg. para fortalecer su sistema inmune y contrarrestar una posible infección de campo por mycoplasmas.
Salmonellae when lodge in ovarian tissue can not be eliminated through antibiotics. eggs obtained from such flock should not be utilized for food. Same is the case for Mycoplasma. It can not be eliminated once it lodges into deeper tissues or joints. So no question of treatment arise. simply cull this flock.

If you do the antibiotic sensitivity teast then you can choose the best one for this infection.
Meanwhile you have to find the serotype of Salmonella. Because pullorum disease shows clinical signs most probably in young ages and fowl typhoid (S.gallinarum) is the disease in adults.
