Calving difficulty in Rubia Callega breed and its genetic improvement



Calving difficulty in Rubia Callega breed and its genetic improvement



3rd World Congress on Genetics applied to Livestock Production, Lincoln, Nebraska, USA, July 16-22, 1986 IX Breeding programs for dairy and beef cattle, water buffalo, sheep, and goats: 451-456



For the Rubia Gallega breed, the principle causes of dystocia, the present status and objectives of selection, problems of the current selection index for selecting sires, and the use of restriction procedures for birth weight in the selection index as a means of decreasing the incidence of dystocia are discussed.
