Congenital and Hereditary Skin Diseases

The document discussed various congenital and hereditary skin diseases in goats. Aplasia cutis was identified as an autosomal recessive trait leading to embryonic epidermal differentiation failure, resulting in ulcers at birth. Hypotrichosis was characterized by reduced hair and hair follicle hypoplasia. Ichthyosis encompassed hereditary keratinization disorders. Congenital goiter and hypothyroidism were linked to maternal iodine deficiency and defective thyroglobulin synthesis, particularly in Saanen-Dwarf Crossbreds. Epidermolysis bullosa, a group of mechanobullous diseases, caused vesicles and bullae after minor trauma, with dystrophic epidermolysis bullosa noted in Anglonubian goats.
