Toe Abscess (Toe Tip Necrosis) in Feeder Cattle

Toe abscess (toe tip necrosis) is most commonly seen in feedlot cattle and is likely subsequent to excessive abrasive damage to the hoof, especially the toe tip. Feet may become infected when the white line is damaged which opens the claw to bacteria, dirt and manure.

Understanding Fan Performance Metrics and Variability

As we move into the summer season, it is important to check for proper function of fans in your operation. When selecting new or replacement fans, it is critical to evaluate the flowrate requirement at the static pressure you will be operating, compare the efficiency of fan options, and ask your equipment supplier for detailed performance specifications.

Air Infiltration in Swine Barns

Air infiltration in large, confined swine operations has been an on-going problem for producers for many years. Regardless of technological advancements in building design and construction, unwanted air penetration continues to be a consistent problem.

Grain Overloads: A Possible Consequence of Cornstalk Grazing

Corn residues are a great source of winter feed, but in certain situations, cattle producers should be aware of the possibility of grain overloads, which can impact herd health.

Minimizing the Neospora Threat by Using Serology in Beef Replacement Heifer Selection

Neospora caninum is one of the lesser-known causes of infectious reproductive failure in beef herds. It’s always possible for herds to encounter new Neospora infections in a given year, but in herds in which it’s already established, using Neospora serology can be one consideration in choosing replacement heifers.

Johne’s Disease Testing in Beef Herds: Testing Plans and Responses

While still somewhat imperfect, testing herd animals for Johne’s Disease is an appropriate tool for producers and their veterinarians to begin to get a handle on the level of infection and to implement sound strategies for limiting the disease’s effects.
