Why is this research important for Alberta ag?
Adoption of Automated Milking Systems (AMS) continues in Canada. A highly stated benefit of AMS is the ability to apply precision feeding programs where the diet is tailored to the individual cow. While theoretically this is possible, it is important to recognize that producers can only change the type or quantity of the pellet delivered in the AMS and all cows eat the same partial mixed ration.
Research has shown that current strategies to achieve precision feeding are not sufficient as the concentrate provided in the AMS may not be fully consumed and that increasing the AMS concentrate allocation results in an unpredictable decrease for the consumption of the partial mixed ration (PMR). As such, studies are needed to understand how pellet formulation can be used to minimize substitution of the PMR or help predict the substitution rate.
This project will test how pellet formulation (high starch vs. high protein) impacts AMS pellet intake, voluntary visits to the AMS, milk and milk component yield, and will have a specific focus on evaluation how pellet composition and feeding level impact PMR intake.
What benefits can producers expect from this research?
Information derived from this project can be immediately adopted by nutritionists to help producers manage feed table recommendations within AMS to develop precision feeding programs.
How will these research findings reach producers on-farm?
Results will be shared at both national and international conferences, through workshops, and through publications in scientific journals.
