SimAngus bulls combine the strengths of two breeds (Simmental and Angus), giving them an economic advantage and making them the sought-after breed for beef on Holstein breeding programs.

PRIMETIME is a superior bull that ranks among the highest HOLSim bulls available. He ranks in the top 5% of the SimAngus breed for several economically relevant traits, such as Calving Ease, Birth Weight, Marbling and Ribeye Area. He’s also ranked in the top 1% for Terminal Index. His Angus sire, G A R HOME TOWN, is recognized for his combination of breed leading carcass traits and pleasing phenotype. His Simmental dam, KBHR IR/JLN ASTORIA G119, is a great young donor with an elite genetic profile.

“PRIMETIME represents unparalleled opportunity to add efficiency, muscle, and marbling to every HOLSim calf he sires. Whether selling day-old beef on Holstein calves or feeding them through harvest, Primetime’s genetics are designed to enhance marketability and profitability,” says bull owner John Irvine of Irvine Ranch.
