DSD 7.6 | Reduce input costs AND improve performance in 1st calf heifers
About this episode
This episode discusses the benefits of opportunistic grazing for heifer development and its impact on milk production.
Opportunistic Grazing is a term used to maximize forage grazed on marginal land for heifer development. Research work completed in Wisconsin nearly a decade ago and recently published defined the differences between heifers reared on pasture for 6 months annually vs those housed in confinement year-round. Heifer development is the second most expensive portion of the dairy enterprise, and feed going into your replacements is the easiest metric to change. Simply by rotating the females between pastures every 2-4 days during optimum grazing conditions, this data suggests a return of nearly 2700 lbs milk during her first lactation when compared to the ‘couch potato’ counterpart on TMR. Listen in today to learn about what observations to expect, how to be responsive and nimble to weather while decreasing cost of production. Additionally, researchers Ken Kalscheur and Carlos Camisa Nova provides a sneak peek at future research being conducted to better understand what is changing in the heifer to improve first lactation performance.
