Transforming Holstein Dairying with Polled Genetics: Craig’s Journey at Calister Holsteins
The Integration of Grazing Systems and Environmental Benefits
In northern Victoria, Craig’s Calister Holsteins is pioneering the use of a grazing system that aligns with pasture growth—providing two-thirds of cows are calved in spring and a third during autumn. Craig firmly believes this system is beneficial for the environment, promotes cow health, and reduces labor issues. By strategically managing a dairy platform of around 121 hectares, which varies based on crop type, including vetch and wheat, Craig simultaneously supports dryland crops.
Sustainable Silage Production and the Role of Vetch
Craig’s farming approach avoids grain production by utilizing wheat tops—harvested for silage after growing most of the way—to enhance the sustainability of feed. Though less high in starch and energy compared to corn, these wheat tops, alongside vetch, make a great nutrient source for cows. A challenge arose due to short spring weather, leading to hay harvest instead of silage, a change that Craig is keenly feeling the impact of.
The Future of Polled Holsteins and Genetic Advancement
At Calister Holsteins, genetics have always been integral in herd management. Craig closely monitors the evolution of polled breeding over the past decade. The recent showcasing of milking daughters from the world-leading homozygous polled sire, Vogue A2P2-PP, underscores this advancement. Craig envisions a future where the Holstein breed could opt to be polled, highlighting the genetic strides with the help of A2P2.
Welfare and Production: Achieving Quality without Compromise
The decision to invest in polled genetics stems from a commitment to cow welfare, without sacrificing genetic quality. Of the last 108 calves, only 17 remain un-polled, signifying effective breeding strategies. Craig reports that A2P2 heifers show excellent performance in their first lactation, exhibiting good type, functionality, and a strong mammary system—a testament to the success of polled genetics.
The Strategic Use of Influential Bulls
The key to successful polled genetics lies in using influential bulls like A2P2 wisely to broaden the genetic pool. Craig plans to continue using top non-polled Holstein bulls to ensure diversity. This balanced approach promises to improve the genetic options for future dairy practices, enriching the gene pool progressively.
Economic Benefits and Industry Impact
Calister Holsteins has contributed significantly to the Genetics Australia program, sending revered bulls including Decipher and Maebull. Craig draws attention to the role of genetics in dairy profitability, supported by projects like the Improving Herds Project showing cumulative economic advantages. He passionately advocates for enhancing herd welfare and minimizing environmental impact, showing how genetics contribute to a sustainable dairy industry.
Insights and Global Perspective from A2P2
Jon Holland of Genetics Australia notes that A2P2 stands out as the second-ranking bull for type in Canada, with his daughters achieving high rankings in Australia. With his global prominence, A2P2’s contribution as a homozygous polled bull offers a pivotal shift in the industry.
