Activities of alkaline phosphatase and acid phosphatase in wing and leg muscles of fighting (aseel) and non-fighting (kalahandi) cocks

To reveal the fighting attributes of Aseel cocks over Kalahandi cocks a comparative histoenzymological study on the locomotory muscles was carried out. The histoenzymological staining for Alkaline phosphatase and Acid phosphatase revealed deposition of brownish black and blackish precipitates of variable intensities respectively. The intensity of deposition was directly proportional to the enzyme activity in the muscle. Acid phosphatase activity was higher in the white fibers of the muscle than red fibers but reverse was true for Alkaline phosphatase. The muscles of Aseel showed a greater enzymatic activity (both Alkaline and Acid phosphatase) than that of Kalahandi cocks. This might be attributed to the fighting ability of Aseel over many other fowl breeds.
