crooked leg:
Pakji (lateral deviation of the foot) if it is caused by the deviation of the bones, especially the Tibiotarsus bone, exactly two of the most important factors in compromising the inappropriate sex of the bed, as well as sudden weight gain outside the framework of the body growth curve
In other words, if the most important cause is the imbalance of calcium and phosphorus in the diet, osteoporosis will develop in the bird, and the poorly developed (quality) bones will not be able to withstand the rapid weight gain of the bird.
In this situation, the force caused by the weight of these hollow bones will cause them to change their direction and rotation.
For this reason, this disease is called TTR or Tibiotarsal rotation
If these conditions happen on hard substrates like concrete, because the blows from the animal’s feet are not absorbed and repelled by the substrate, it will aggravate the condition and increase the incidence of disease (just like the bending of a nail that is hammered into a hard surface). )
Therefore, the most important underlying factors of this disease are:
1. Lack of balance in the amount and especially the ratio of calcium and phosphorus in the diet
2. Improper substrates, especially concrete
3. Rapid weight gain of the bird (before the sufficient quality of the bones)
You can read other cases in the TTR section of the book Diseases of Ostrich Movement Organs.
