With greetings and respect to the esteemed members of the group, dear colleague Dr. Iraqi and Dr. Shahabi
What is characteristic of this disease is more prevalent in collections that do not use standard and quality rations
In the collections that use formulated rations under the supervision of qualified experts, the occurrence of this complication is much less and almost zero.
About 10-12 years ago, this disease spread in the central regions of the country, especially Isfahan province, and gradually spread to other regions.
Personally, I believe that the main cause of this syndrome is the general weakness, especially the nervous, muscular and immune systems of the birds that are fed with diets lacking the quality necessary for ostriches.
You are reminded that the most common nutritional grounding in large livestock is milk fever, which is mainly caused by the lack of calcium in the blood of newborn cows and causes disruption in muscle contraction activity and as a result, the animal’s inability to maintain its weight and balance. It is possible and has a management and nutritional cause
Many micronutrients and trace elements have essential and vital roles in the growth, metabolism and maintenance of the body’s vital activities, and their deficiency leads to failure or disruption of the relevant functions.
For example, I can give an example of the contraction of muscles or the transmission of nerve messages, the disruption of which eventually leads to paralysis and grounding.
As the old saying goes, light becomes light if the diet does not contain enough amino acids necessary for the bird
You know that one of the most important components of the immune system are antibodies and immunoglobulins, the majority of which are proteins.
And the components of proteins are amino acids
Now, if a diet is deficient in protein and amino acids, especially essential amino acids (which are almost not synthesized in the body of an animal that consumes a plant diet and need to be supplied from sources outside the body), such as methionine and lysine, and in the next ranks , tryptophan, threonine and Okay, of course that bird will have an immune system problem as well.
If such a bird encounters the lowest viral load of any disease (for example, Newcastle disease, which is a rumor in the country and is present in almost all parts of the country), it will quickly become infected and its tests will be positive.
In this situation, the veterinarian and the owner of the herd look for treatment and prevention and miss the opportunity for treatment
It is true that this herd is currently infected with Newcastle disease, but first of all, the main cause of the herd’s problem is something else
Secondly, assuming the Newcastle treatment of this herd, the problem of grounding it still remains
