FeedPRO optimizes selection for increased production and moderate body size while maintaining body condition score and daughter fertility. This revolutionary index designates sires with the genetics to improve income over feed costs and maintains health and reproductive traits.

Throughout this directory, you will ﬁnd sires sporting the special designation icons listed here along with their descriptions. Use these tools to choose sires that best reﬂect your management style to meet your goals.

This icon identiﬁes sires with sex-sorted semen available. More heifers is not out of reach with our research-backed gender SELECTED sires. All gender SELECTED semen is processed using Ultraplus technology.

The FertilityPRO designation identiﬁes sires with semen that will likely improve pregnancy rates. This designation is assigned by examining industry service Sire Conception Rate (SCR) values, along with intensive in-house semen quality evaluations.

Sires earn the SHOWCASE designation through outstanding breed-leading Type or show-winning pedigrees. Turn to this designation to produce your next show winner or improve the overall type in your herd.

Look for the gender SELECTED 4M icon to identify sires with sex-sorted semen available in 4 million sperm doses. All gender SELECTED semen is processed using Ultraplus technology.

The Elite Sexed Fertility icon designates sires that can help you achieve the highest sex-sorted semen conception rates, enhancing your return on investment! This innovative designation distinguishes our highest performing sires for sex-sorted semen in both 2M and 4M products.

GrazingPRO sires improve the proﬁtability of grass-based production systems by transmitting greater longevity, improved mobility, moderate stature, greater component yields and superior production - all while not compromising Daughter Pregnancy Rate (DPR) and Somatic Cell Score (SCS).

Sires which excel in multiple indicators of mastitis resistance are more likely to deliver genetic improvement. Mastitis ResistantPRO uses a combination of CDCB Mastitis Resistance, CDCB Somatic Cell Score (SCS) and Zoetis Mastitis Resistance.

RobotPRO sires transmit the desired traits for robotic milking systems. These sires were selected by focusing on component and milk yield, milk quality, udder health as well as functional udder traits. Use these sires to create the next generation of proﬁtable cows for your speciﬁc milking system
