Impact of winter feeding and vaccination strategies on carcass outcomes in beef cattle
Project Details
Project Lead: Kim Ominski (University of Manitoba), Argenis Rodas Gonzalez (University of Manitoba)
Collaborators:
Years: 2016
Project Status: Complete
Funding & In-Kind Support: Growing Forward II, Growing Innovation - Agri-Food Research and Development Initiatives, Manitoba Beef Producers, AUPC, Manitoba Beef and Forage Initiatives
Location: Johnson Farm
Scope: Research
Keywords: Livestock Performance, Extended Grazing
Approach
This project evaluated the impact of management practices on carcass outcomes in beef cattle production systems:
Differences in carcasses of the offspring of cows supplemented with corn on a low-quality forage-based diet during gestation.
Effects of a needle-free injection device compared to needle syringe on injections site reactions in Angus steers vaccinated and boostered with modified live bovine viral diarrhea.
Key Findings
Carcass outcomes: Steers from both maternal treatments did not differ in carcass traits and meat quality. Maternal corn supplementation did not affect the carcass outcomes of the offspring.
Needle-free injection device: Injection site lesions were not observed in the carcass tissue of steers from either treatment. The use of needle-free technology does not damage tissue and could eliminate the presence of broken needles.
