Risk factors identified for respiratory disease

Dec 02, 2022

Calf health is a major focus for beef cow-calf producers and their veterinarians for good reason.

A recent paper in the journal, Translational Animal Science, highlights some of the findings from the western Canadian cow-calf surveillance network focusing on calf health issues. Dr. Cheryl Waldner and colleagues from the Western College of Veterinary Medicine, the University of Calgary School of Veterinary Medicine and Big Sky Health Analytics in Vermilion, Alta., were the authors of the paper. The study used data from 89 western Canadian cow-calf herds to estimate the frequency of disease treatment in pre-weaned calves.

As we’ve seen in other studies, bovine respiratory disease (BRD) in calves has become the predominant reason for young calves to receive antibiotic treatments. Slightly more than half of the herds reported that they had treated at least one calf for BRD prior to two months of age.

Video: Winter Canola Trial in Mississippi | Can It Work for Double Cropping? | Pioneer Agronomy

Can winter canola open new opportunities for growers in the Mid-South? In this agronomy update from Noxubee County, Mississippi, Pioneer agronomist Gus Eifling shares an early look at a first-year winter canola trial and what farmers are learning from the field.

Planted in late October on 30-inch rows, the crop is now entering the bloom stage and progressing quickly. In this video, we walk through current field conditions, fertility management, and how timing could make this crop a valuable option for double-cropping soybeans or cotton.

If harvest timing lines up with early May, growers may be able to transition directly into another crop during ideal planting windows. Ongoing field trials will help determine whether canola could become a viable rotational option for the region.

Watch for:

How winter canola is performing in its first season in this Mississippi field

Why growers chose 30-inch rows for this trial

What the crop looks like as it moves from bolting into bloom

Fertility strategy, including nitrogen and sulfur applications

How canola harvest timing could enable double-cropping with soybeans or cotton

Upcoming trials comparing soybeans after canola vs. traditional planting

As more growers look for ways to maximize acres and diversify rotations, experiments like this help determine what new crops might fit into existing systems.
