Full Blood Aberdeen bulls are big enough to cover commercial cows.
Mature American Aberdeen bulls will generally fall into a range of 45-48 inches measured at the hip and weigh from 1,300 to 1,600 pounds.
Mature cows generally measure from 42-46 inches at the hip and weigh between 900 and 1,100 pounds.
The American Aberdeen Moderator® and Aberdeen Plus cow, with an average weight of 1,100 pounds, requires 27 percent less feed than a 1,500 pound cow and will wean more pounds of calf per acre.
A 1,500 pound cow eats 3 percent of her body weight = 45 pounds. An 1100 pound cow eats 3 percent of her body weight = 33 pounds.
For years, U.S. registered and commercial cattle have been bred bigger, less efficient and with less muscle. The result has been higher input costs per cow and reduced stocking rates, while national average weaning weights have stayed the same or gone down for the last 24 years.
Pedigree and Genetic Defects
The original herd was developed at the Trangie Research Center in New South Wales, Australia. Animal Scientists began with a herd of registered Aberdeen Angus cattle, purchased in 1929 from Canada, that were carefully selected for efficiency and smaller frames. The end result was a breed of small, black, polled cattle of pure Aberdeen Angus descent.
The American Aberdeen focus is back to the basics…efficiency, quality, phenotype, longevity, and carcass. EPDs fail to take into account many of the breed’s benefits.
American Aberdeen Cattle are free of known genetic defects, including the dwarf gene.
Commercial heifers bred to Full Blood American Aberdeen bulls calve easily and breed back quickly, reducing the calving interval.
Finishing and Carcass
Aberdeen carcasses possess excellent beef characteristics of taste, texture and tenderness as well as exceptional ribeye area per hundred pounds of body weight, which translates to very high-yielding, high-quality, high-value beef carcasses. Muscle fibers are smaller, making the beef more tender than other breeds.
American Aberdeen Moderator and Aberdeen Plus are well suited to grass-fed production as they are easy fleshing and will finish on native and improved pastures, producing high value carcasses with minimum input costs.
The NDSU Dickinson Research Center has 15 years of data showing that F1 Moderator cattle hit commercial specification for carcass, including CAB. F1 steers finished in the feedlot at 1250 to 1350 pounds.
