Observation On Congenital Loco, A Hereditary Defect In Three Flocks Of Chicken At Ibadan

Abstract

Congenital loco, a monogenic, sex-linked hereditary defect was observed in three flocks of chicken at Ibadan. Mortality at the end of the first 4 days of life was unexplainably high. Noticeable signs were birds thrown off balance with necks thrown backwards, chicks unable to feed nor drink. Subsequently, they got weak, slumped and died.

Keywords: congenital loco, hereditary defects, lethal factor, sex-linked, pullets.
