Five days old chicks of Fayoumi were fed a diet of 40% of crude protein to 14 days of age for screening the abnormality induced high protein diet feeding.
After screening, chicks were divided into two groups of the normal group and the abnormal group which showed articular gout and inanition.
Gout line (G-line) and non-gout line (N-line) were established from gout group and normal group respectively.
At the selected second generation, percent incidence of abnormality in gout line reached 100 percent, and that in non-gout line was 5.8 percent.
It was suggested that the gout was the autosomal single recessive character from the results of reciprocal crossing experiment with both lines.
