The April 2025 genetic evaluations have arrived, bringing significant changes across both genomic and daughter-proven Holstein sire lists in Canada. These evaluations reveal notable movement in rankings and genetic trends compared to the December 2024 data.
Genomic Bulls Demonstrate Impressive Genetic Progress
OCD MONKEY-ET leads the GLPI Genomic Bulls list with an impressive GLPI of 4079. This young sire showcases exceptional production traits (+1267 kg Milk, +134 kg Fat, +74 kg Protein) and strong conformation scores (Mammary System +11, Dairy Strength +12).
PROGENESIS IMPULSE follows closely at 4078 GLPI, excelling particularly in fat production (+132 kg) and daughter fertility. The top five is rounded out by ADAWAY BEYOND FITNESS-ET (4062), OCD MILAN-ET (4059), and PROGENESIS MELNIK (4038), all demonstrating the balanced breeding approach favored in the Canadian system.
Notable newcomers to the top genomic list include FRAHOLME VEC TRITON-PP, which ranks 30th with a GLPI of 3952. This polled sire offers exceptional production credentials (+940 kg Milk, +105 kg Fat, +63 kg Protein) and impressive fat and protein deviations (+0.58% and +0.25%, respectively).
Daughter-Proven Bulls Show Stability with Key Movements
S-S-I PR RENEGADE-ET maintains his dominance on the daughter-proven list with an LPI of 3850, supported by outstanding production (+1154 kg Milk, +98 kg Fat, +67 kg Protein) and impressive feet and legs (+14). His reliability is bolstered by 1509 daughters in 457 herds.
SIEMERS RENEGADE ROZLINE-ET ranks second with an LPI of 3835, showing exceptional fat production (+144 kg) with a remarkable +1.24% fat deviation. GENOSOURCE JOHNBOY-ET rounds out the top three with an LPI of 3827 and balanced production and fitness traits.
Conformation Specialists Continue to Impress
WALNUTLAWN PG BRIGHTSTAR leads the Conformation Genomic Bulls list with an outstanding conformation score of +20, supported by strong production credentials (+1285 kg Milk). WALNUTLAWN PG LOVESTORY and PROGENESIS ARTORIUS follow closely, with confirmation scores of +18.
Among daughter-proven conformation specialists, BLONDIN ENERGY leads with a conformation score +17, excelling in the mammary system (+13) and feet & legs (+13). BLACK SILVER CRUSHABULL STAN and VOGUE A2P2-PP round out the top three with scores of +16 and +15, respectively.
Emerging Genetic Trends
Several key trends are evident in the April 2025 evaluations:
- Balanced Breeding Focus: Top bulls across all lists demonstrate a balance between production, conformation, and fitness traits.
- Polled Genetics Gaining Ground: Several polled and homozygous polled bulls, including FRAHOLME VEC TRITON-PP and VOGUE A2P2-PP, appear in the top rankings.
- Improved Health Traits: Enhanced fitness metrics indicate continued emphasis on cow longevity and health, particularly for daughter fertility and somatic cell score.
- Production Efficiency: Bulls combining high component yields with positive deviations are particularly valued, reflecting the industry’s focus on component-based payment systems.
As producers evaluate these new rankings, they’ll find numerous options for genetic improvement across all trait categories. The April 2025 evaluations demonstrate the Canadian dairy industry’s continued commitment to balanced genetic progress that enhances production efficiency and cow longevity.
