[Histometric findings in the adrenals of the domestic pig with reference to constitutional defects]

The Piétrain pigs are significant different from the German Landrace and the Edelschwein in the histometrical parameters of the adrenal glands like cortex and medulla part, height of the cortex regions, part of adrenaline and noradrenaline producing cells. The weight of their adrenal glands is less than in the other races but their part of Zona fasciculata and of adrenaline producing cells is comparably high. These findings let expect distinct reactions on stressors. There are no hints on insufficiency of the adrenal glands. The histometrical parameters and the blood cortisol levels are discussed with regard to deficiencies in meat quality.
