What is FeedWise ONYX semen?
FeedWise™ ONYX™ semen is a blend of multiple Stabilizer sires that are carefully selected to prioritize fertility and creating a premium beef x dairy calf. To optimize results, FeedWise ONYX semen comes in three different blends that create the ideal beef x dairy calves based on the breed of the dam:
- ONYX™ BLEND 1 HO: Genetically optimized for use on Holsteins, focusing on marbling and muscling and less emphasis on frame score.
- ONYX™ BLEND 2 JE: Genetically optimized for use on Jerseys, focusing on above average carcass weights, greater than average daily gain, and more frame score.
- ONYX™ BLEND 3 HO/JE: Genetically optimized for use on Holstein/Jersey crossbred cattle, focusing on a combination of the aforementioned traits.
Each of these blends are available in options for use on heifers or cows.
Genetics & Sires
What are Leachman Stabilizer™ cattle?
Leachman Cattle has been developing their own proprietary line of Stabilizer genetics for more than 30 years. Leachman Cattle alone breeds more than 10,000 cows per year, which ranks Stabilizers among the top 10 breeds in the U.S.
Stabilizers are made up of British and Continental breeds, including Angus, Red Angus, Simmental, Gelbvieh, and South Devon. As a multi-breed composite, their combination of muscle and marbling makes them highly desired by cattle feeders.
Why are Stabilizers ideal for creating pregnancies on dairy females?
FeedWise ONYX uses semen from Stabilizer sires that are carefully hand-selected for optimal performance on dairy females. In addition to being known for creating calves that are vigorous, alert, and healthy at birth, these sires are known for their high fertility, calving ease, and ability to create moderate birthweight beef x dairy calves off to a good start.
Program Logistics
How do I get paid for calves produced from FeedWise™ ONYX™ semen?
When a calf is produced from FeedWise™ ONYX™ semen, a GK Jim Farms regional representative will work with you to determine the fair market value of the calf and pick the calf up at your farm.
At the time of pick up, the calf is assessed, calf records are collected, and a record is logged to create a transparent traceability record for the animal. GK Jim Farms will summarize cattle receipts weekly, generate a receipt, and send it to you by email. Once you approve the receipt, GK Jim Farms will issue your payment via ACH.
We will apply your premium credit to your Alta account on a regular basis for each calf sold. Once posted to your account, these credits can be used to purchase anything from Alta, including semen, products, services, and more.
