Beef Cattle Producers Must Be Vigilant To Mitigate Herd Health Risks

Beef cattle producers should be observant when conducting annual health vaccination protocols on their cattle, according to Texas A&M AgriLife Extension Service experts.

Though not a statewide threat, the fever tick has resulted in some herds in far South Texas to be subject to a quarantine zone. This topic, as well as proper vaccination protocol and techniques, were discussed at the recent Texas and Southwestern Cattle Raisers Association Convention in San Antonio.

“Surveillance is key,” said Dr. Joe Paschal, AgriLife Extension livestock specialist in Corpus Christi. “We want to enlist veterinarians and ranchers to be more observant of ticks on cattle. These fever ticks tend to prefer soft tissue along the dewlap, brisket, forearm and back in the flank area.

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
