Can Livestock Utilize Moldy Grain?

While livestock producers know that moldy grain and forage are not ideal feedstuffs, they also know that stored feed occasionally contains a small amount of visible mold, and that their animals consume it with no obvious adverse effects. The question arises, how much mold is too much for a feed to be unsuitable for animals?

2019 Corn Fungicide Field Trials Summary

What Goes Into Calculating Yardage?

Yardage cost is the non-feed cost per head for every day that an animal is fed harvested feed in some form of confinement. Yardage is usually associated with calves and yearlings in the feedlot, but this concept can apply to drylotted or wintering cows as well.

Managing Weed Seed in 2020

Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.

Harvesting Silage on a Wet Year: Moisture is Critical

Fall is on its way in South Dakota. However, with many flooded and saturated fields, some producers are growing concerned that there will be little opportunity to harvest silage before corn dries down past desired moisture levels or frost occurs.

Southern Rust Developing Late in Corn

Southern rust was found in a few corn fields scouted last week. This rust is developing very late in the season and therefore its impact on corn yield will be minimal.

Valuing High-Moisture Corn and Earlage

A key advantage to using commodities that meet standard specifications and are frequently traded is that it is very easy to establish an economic value that is accepted by most users. The marketplace sets the value of corn, and other feedstuffs on a daily basis, provided those products meet some set of standard specifications.

Prussic Acid Poisoning

As the first frost date approaches, producers often have concerns about the risk of prussic acid poisoning in livestock. Certain forage plants, especially sorghums and related species are associated with an increased risk of death loss because of prussic acid poisoning.

Multi-Species Grazing as an Alternative to Pasture Spraying

Broadacre spraying of pastures is intended to reduce undesirable plants and increase grasses for livestock. This practice often results in unintended consequences, including damage and reduction of native forbs and reduced profitability. One approach to managing perceived “weedy” plants is incorporating different species of livestock into a grazing operation.

Marestail Fall Control

Marestail (also known as horseweed) is considered either a winter annual or biennial species that is often difficult to identify at the rosette stage. In the Dakota’s, marestail will germinate in the fall and bolt in the spring.
