At this Johnson Research Field, MBFI is researching cow-calf nutrition and needle-free vaccination. This page provides information about this particular research project; including the background, objectives, and updates.
In Western Canada, increased nutrient demand associated with decreased temperatures and increased fetal growth may lead to nutrient deficiencies in pregnant cattle. As a result of compromised maternal nutrition fetal muscle development, body weight gain, hot carcass weight, back fat and marbling of their offspring may result.
A needle-free vaccination strategy is being developed for its use in cattle, but its effect on carcass outcomes has yet to be tested. These two concepts will be tested during this three-year research project.
- Analysis of the samples from the intital work at NDSU in Phase 1 of the project is underway
- Steers have been moved to MBFI site in Brandon and intake studies are on going.
As of spring 2016 - This project is led by U of M professor Dr. Kim Ominski in collaboration with researchers from NDSU and part of the project will take place at MBFI. The initial stages of the project have already begun at NDSU; 60 cows are being fed two different diets. After the calves of those cows are born they will be vaccinated using two different strategies: needle-syringe and needle-free.
When the calves are ready to be backgrounded (fall 2016), they will be brought to the Johnson site where their intake on pasture will be recorded. The cattle will then move on to their next location for finishing and slaughter data collection.
