How to treat and prevent Chronic Respiratory Disease (CRD)?

Posted by Gamefowl Supplies on

Mycoplasma gallisepticum is considered the primary cause of Chronic Respiratory Disease (CRD) in poultry. The most common symptoms of Mycoplasma gallisepticum infections in poultry are eye problems and inflammation around the face. Other symptoms include open-mouth breathing and gurgling throat sounds. The severity is classified into two phases:

Phase 1

The sudden appearance of wetness around the eye sometimes referred to as one-eye colds. One eye colds appear as wetness around the eye with minimal swelling of the eyelids. Give AMBROXITIL POWDER into the drinking water for 7 days.

When no response is seen, the disease has likely progressed to stage two or underlying diseases may be complicating the infection.

Phase 2 

As the infection progresses, further symptoms may include swelling of the orbital sinus ("donut" shaped swelling around the eye), pussy eye discharge, sticky eyelids, and open mouth breathing. Afflicted birds and the entire flock should be treated when this stage of the disease is seen. Treatment involves an administration of AMTYL Tablets for 7 days.

To accelerate recovery and help reduce the effects of any stressful factors, VitminPRO Powder should be mixed into feed each day for 7 days. For stage 2 of this disease, this treatment should give a good response. 

The remainder of the flock should receive a 7-day treatment course as described for stage 2 of this disease.

Birds that have recovered from clinical signs of the disease have some degree of immunity. Such flocks, however, carry the organism and can transmit the disease to susceptible stock by direct contact or by egg transmission to their progeny.

The complicated form of CRD occurs when other underlying diseases are involved. A virus infection called Infectious bronchitis (IBV) is a highly contagious disease causing acute illness, coughing, sneezing, and impaired kidney function. IBV may precipitate outbreaks of Mycoplasma gallisepticum, although when present together, mortality in adult flocks is negligible. There is, however, a marked reduction in egg-laying, and mortality in broilers can be high especially during colder months.

E.coli infections have also been found to be a frequently complicating organism while other diseases that may complicate CRD include Mareks disease (Herpes), ILT (infectious laryngotracheitis), and Pox virus.

Prevention is still better than cure

It is difficult to prevent infections caused by Mycoplasma gallisepticum by natural means or by simple cleanliness routine because the disease is transmitted by eggs. Vaccinations have not proven to be a successful preventative measure because CRD is so often complicated by underlying diseases. The proven and tested method of prevention is by boosting the immune system of your flock through the use of VitminPRO Powder, a probiotic multivitamin supplement packed with vital nutrients and minerals formulated for chickens significantly reduce the infection rate of mycoplasma gallisepticum and e.coli bacteria to as low as 0.1%.
