Select Designations

No matter what you’re looking for, Select Sires has something for everyone. Whether you’re interested in Type, Yield, Net Merit $, or other criteria, we feature bulls with special designations to denote top sires in selected categories.

WellnessPRO Final 1

Always passionate about customer success, Select Sires is collaborating with Zoetis to provide two innovative indexes for its Holstein lineup sires, Wellness Trait Index™ (WT$™) and Dairy Wellness Profit Index™ (DWP$™), which uses wellness trait information from the CLARIFIDE® Plus genomic test to predict lifetime profitability based on additional wellness information. The top WT$ sires at Select Sires will be designated WellnessPRO™ to identify the sires with the greatest chance to make a positive impact on wellness by reducing the genetic risk of common dairy cow diseases.

Superior Settler 4C Print copy 1

While the greatest variables affecting pregnancy rates are accuracy of heat detection, inseminator technique and other management factors, looking at all available fertility values of individual sires can help. Through evaluation of the Composite Fertility Index (CFI) and Sire Conception Rate (SCR), along with intense semen quality evaluations, these elite sires earn the designation of Superior Settler.

RobotPRO Final 1

Select Sires recognizes the growing number of automated milking and feeding systems on dairy farms and has identified sires that transmit the desired traits for robotic milking systems. These sires were selected by focusing on component and milk yield, milk quality, longevity and durability as well as functional udder traits. By using these sires you can create the next generation of profitable cows for your specific milking system.

New FeedPRO

High feed prices have generated greater interest in selecting for feed efficiency. In 2009, Select Sires’ genetics staff took a closer look at the large variety of traits measured by current USDA genetic evaluations to see if they could identify some key indicator traits for producing greater income over feed costs. After an extensive review of available research, Select Sires introduced FeedPRO as a sire selection tool for the dairy producer concerned about feed costs and their overall effect on profitability. The index identifies the top 20 percent of Select Sires’ lineup that transmit the traits consistent with more income from less feed–sires that maximize production while moderating size and improving long-term fitness and productivity. The research behind FeedPRO confirms that it works.

Pasture-based dairying can be a viable option to produce milk profitably. Based on sound science and research, Select Sires’ grazing specialists are selected to increase the profitability of grazers by transmitting superior production yields, transmitting greater longevity and mobility, moderating stature, and improving component yields–all while not compromising fitness traits such as Daughter Pregnancy Rate and Somatic Cell Score.

small4C genderSELECTed SexedUltra Logo

You don’t have to sacrifice genetics for more heifer calves. Whether you are breeding for type, production, health traits or a combination, Select Sires has you covered with high-ranking gender SELECTedTM bulls.

To minimize the variance in success of our gender SELECTedTM sires, Select Sires closely scrutinizes both the semen quality and field fertility data of conventional semen before a bull is allowed to qualify as a candidate for sex-sorting. Select Sires continually collects conception data from herds using gender SELECTedTM semen to calculate sexed semen fertility deviations and removes bulls from the lineup that perform unacceptably.

Dairy producers who have used Select Sires’ gender SELECTedTM semen value the opportunities they have–more heifers for sale, replacements and internal expansion, and smaller calves from first calf heifers.
