Be on the Lookout for Black Grass Bugs

It’s time to begin scouting pasture and wheat for the presence of black grass bugs. Last year, we saw the highest populations in areas of Central and Southwestern South Dakota. If left untreated, black grass bug populations tend to increase year after year.

Aphid Populations Being Observed in Wheat

During the past couple of weeks, reports of aphid populations in wheat fields have slowly been increasing. Typically, the initial aphid populations are observed earlier in the season, but the 2019 spring may have delayed infestations.

Fly Control Considerations for Cattle on Pasture

Along with being irritants to livestock, horn flies, face flies and stable flies are economically important to producers due to their negative impacts on milk production and calf weaning weights.

Sheep Breeds

Everyone has heard the fairytale “Baa Baa Black Sheep Have You Any Wool?” but what about the double-coated California Red, the multi-colored Katahdin sheep with hair, or the East Friesian dairy ewe that produces over 1,100 pounds of milk a year? Sheep come in different shapes, sizes, and colors and all of them provide different functions and uses for producers. These can range from meat, wool, and milk production or a combination of characteristics.

National Sheep Improvement Program: Performance-based data you can rely on

Sheep producers continually look for opportunities to improve their flocks through the introduction of genetic traits that will contribute to both improve the performance and physical appearance of the offspring. For hundreds of years, producers used the phenotype or physical appearance traits to select replacement stock, followed by performance trials and wool testing to quantitatively define the traits a specific animal may possess.

What are Those Gigantic Flies?

As we progress later into the summer, we commonly see an increase in horse fly activity.
