Johne’s Disease Testing in Beef Herds: Looking at the Available Tests
Once thought to be a dairy cattle problem, Johne’s Disease is increasingly a topic of conversation for beef seedstock and commercial producers alike. An understanding of the Johne’s Disease testing options available is a good first step in devising a herd health plan.

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.

Importance of Chicken Infectious Bronchitis Virus: Q&A
Infectious bronchitis virus (IBV) is a coronavirus that infects chicken flocks, causing respiratory disease. Some IBV isolates can result in a kidney disease (nephritis). Drop of egg production in laying hens is an important sign for IBV infection.

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.

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.

How Important Is Water Quality to Livestock?
Water is the most important nutrient to all livestock animals and is sometimes overlooked. Poor quality water can have a negative effect on growth, reproduction, and general productivity of the animal.

How Do Sulfates in Water Affect Livestock Health?
Poor-quality water will cause an animal to drink less. As a result, they also consume less forage and feed, which leads to weight loss, decreased milk production and lower fertility.

Precautions for Grazing Weevil-Infested Alfalfa
Alfalfa weevil populations are high this year, creating challenges for producers. Questions have arisen on how to get some value out of the forage by grazing it rather than putting it up for hay.

How Would Veterinary Diagnostic Labs Test for African Swine Fever?
What would African Swine Fever testing look like through the lens of our veterinary diagnostic laboratories? Interestingly, we know exactly what it looks like, because it’s already being done at sites such as the Animal Disease Research and Diagnostic Laboratory at South Dakota State University.

Safe Canning Recipes
One of the most common errors in home canning is not using a scientifically tested recipe. Canning a family recipe is risky as it can cause spoilage and foodborne illness.
