Mycoplasma combined with Salmonella in rearing

Published: December 19, 2014
By: Mike Gabler

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. ayaz

Typing of salmonella is important and its proper diagnosis , in the same way for MG i will say go for the Proper protocol for its diagnosis and confirm it with PCR . Treating is not any issue as both these Diseases will not cause so much mortality in a flock of 20K and also in 16 wks of age ... so for the treatment start with 3rd Generation ie Enro for a 3-5 days and then followed by Tiamulin at least 45 -50mg/kg b.wt for 3-5 days and repeat it at interval of every 4 wks will work . Meanwhile using of Tylan premix in Feed at least 180 mg /Ton will also be good in the start at this age . Acidification of water will also help if the Flock is +ive for Salmonella and Eggs are not used for Human consumption,.. Please Read More for Salmonella in the Following Article .

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.
