Understanding the normal physiological parameters and its modifications under pathological conditions is essential for diagnoses, treatment and prevention.

In poultry, many researchers have offered this information but it is spread among many publications. In these graphs, we have summarized the main blood parameters affected by genetics, gender, age and pathological conditions.

The statistical description of our work can be visualized in each column. We will continue feeding this database as soon as more data becomes available.
