The weight of the paired adrenals in pigs weighing 75 to 113kg is estimated in the following isometrical equations: Y=0.018X+3.618 for barrows and Y=0.014X+4.040 for gifts (where Y is the paired adrenal weight in g and X the body weight in kg). These equations mean that the ratio of adrenal weight to body weight decreases with gaining in body weight in both barrows and gilts. The adrenal glands of standard market hogs (90-100kg) in Japan may weigh 5.2 to 5.4g. In females, the relative weight of the adrenals decreases with age, at least up to puberty and when the body weight reaches over 120kg (10 months of age, or older), it increases gradually. This may not be the case with males. Both relative and absolute weights of the adrenals are probably greater in sows than in boars. In more than 50 per cent of the animals of each group, the left adrenal is larger than the right.In addition, the shape of the adrenal glands was described.
