Congenital Hypotrichosis and Partial Anodontia in a Crossbred Beef Calf

Abstract — Clinical examination, skin biopsies, skull radiographs, and DNA analysis of a 2-day-old Red Angus- Charolais-Simmental cross bull calf confirmed the diagnosis of congenital hypotrichosis and anodontia defect (HAD), also called anhidrotic ectodermal dysplasia, which is a rare anomaly caused by a deletion in the bovine EDA gene on the X chromosome............

Avoid Cattle Defects With Mating Decisions

With expected progeny differences and genomic testing, beef cattle breeders can predict calf structure and performance traits.

Researching pedigrees and sire summaries creates a forecast of the future, but one of the most important genetic predictions is often overlooked.

Many beef cattle genetic deformities are now tested for in pedigrees and should be evaluated when making mating decisions. Being aware of potential defects and then breeding based on probabilities can keep herd size growing and herd quality admirable.

New Tests Available for Cattle Genetic Disorders

Genetic defects in cattle have made their way to the forefront again. The changing breeding landscape and intense selection have led to the presence of these defects.

Although not a new problem, genetic defects have been seen as far back as the 50s in some breeds. Recently, however, they’ve become more prevalent than producers and breed associations would like.
