German sire just hit RZG 148 – that’s $2,400 more lifetime profit per cow than industry average bulls.

EXECUTIVE SUMMARY: Just spent the morning analyzing Germany’s August 2025 Holstein evaluations, and the results are frankly stunning. The pace of genomic progress is relentless—we’re seeing genomic bulls like Evenstar and Pennywise hitting an incredible RZG 164, while the top daughter-proven bull, Zivet, commands the proven rankings at an already elite RZG 147. For breeders, that 17-point RZG gap between the proven king and the new genomic leaders can translate to thousands of dollars in lifetime profit per cow. The standout in the proven list is Zivet at RZG 147, delivering over +1,900 kg of milk with phenomenal components. In the Red Holstein world, Ginger leads the proven sires at RZG 143 with a staggering +2,638 kg milk proof. But the real story is genomics: sires like Schach (RZG 161) and Evenstar (RZG 164) are pushing production and functional traits to new heights simultaneously. Germany’s focus on polled genetics is also paying off, with bulls like Create P offering elite merit without horns.

The German Holstein breeding landscape continues to demonstrate remarkable genetic advancement, with the August 2025 evaluations revealing exceptional bulls across both proven and genomic categories.

Daughter-Proven Excellence

The daughter-proven category is dominated by Zivet, who commands the rankings with an RZG of 147. This exceptional bull demonstrates remarkable balance, with production figures of +1,971 kg milk, +88 kg fat, and +86 kg protein. His functional trait profile is equally impressive, featuring a longevity score (RZN) of 121 and an overall health score (RZGes) of 113. With 422 daughters proven across 184 herds, Zivet‘s genetic merit is built on substantial reliability.

Following closely, Mirco maintains his position as a top-performing professional with an RZG of 144. His production profile shows +1,363 kg of milk, +65 kg of fat, and +59 kg of protein, combined with strong functional traits, including an RZN of 122 and excellent udder health scores.

Genomic Innovation

In the genomic sphere, Evenstar leads with an outstanding RZG of 164. This Real Syn son exhibits exceptional genetic potential, with projections of +2,090 kg of milk, +120 kg of fat, and +69 kg of protein. His balanced profile includes strong functional traits with an RZN of 134 and an RZGes of 109, positioning him as a premier choice for progressive breeding programs.

Matching the top spot is Pennywise, another genomic standout with an RZG of 164. This Picard son shows remarkable production potential (+1,761 kg milk, +124 kg fat, +76 kg protein) while maintaining an excellent balance of functional traits.

Red Holstein Distinction

The Red Holstein proven category showcases Ginger at the pinnacle with an RZG of 143. Proven through 510 daughters, this Gywer RDC son delivers a staggering +2,638 kg of milk, +85 kg of fat, and +90 kg of protein. His exceptional production is complemented by solid functional traits, including a longevity score (RZN) of 115.

Ghost Red emerges as another proven leader with an RZG of 139. His proof includes +1,904 kg of milk, but with a negative fat deviation, alongside a positive protein contribution, demonstrating the genetic diversity available within elite Red Holsteins.

Leading the genomic Red Holstein evaluation, Schach achieves an impressive RZG of 161. This Skat P RDC son represents the cutting edge of genomic selection, with production estimates of +1,910 kg milk, +98 kg fat, and +63 kg protein and a strong longevity potential (RZN 137).

Create P and Coco Red P both achieve an RZG of 161, demonstrating the depth of excellence in the Red Holstein population. Create P projects +1,291 kg milk, +65 kg fat, and +66 kg protein, while Coco Red P delivers +2,006 kg milk, +67 kg fat, and +80 kg protein.

Key Genetic Trends and Market Implications

The August 2025 evaluations highlight several key trends shaping the modern dairy industry. The emergence of genomic bulls like Evenstar and Pennywise with RZG values of 164 indicates that selection programs are successfully pushing the boundaries of genetic potential.

This genetic gain is directly translated to the milk tank. Production capabilities have reached new heights, with sires like the proven bull Ginger (+2,638 kg) and the genomic leader Evenstar (+2,090 kg) setting new benchmarks for milk yield while maintaining functional trait balance. This addresses the core need for profitable and productive cows.

Furthermore, these rankings reflect a clear response to market demands. In component-driven payment systems, the exceptional fat yields of bulls like Pennywise (+124 kg fat) are incredibly valuable. Simultaneously, the strong representation of polled genetics among top performers, such as Create P, offers producers a market-friendly solution to eliminate dehorning without sacrificing elite genetic merit.
