Managing Cow/Calf Pairs With Excess Spring Moisture

Flooding, blizzard conditions and excess snow can wreak havoc on livestock producers. While there is little one can do to stop the melting snow and rising waters, we can try to manage around the water by preparing alternative livestock and feeding areas.

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?

Poisonous Plants on Rangelands: Deathcamas and Lupine

With prolonged drought conditions throughout many areas of South Dakota, there is an increase of invasive weeds and poisonous plants on rangelands. Identification of poisonous plants is crucial to ensure livestock production is not compromised.

Poisonous Plants on Rangelands: Hemlock, Halogeton and Buffalo Bur

Several species of poisonous plants are invasive and can easily establish dense stands when there is a disturbance on rangelands. Hemlocks, halogeton and buffalo bur can all be found throughout South Dakota and are toxic to livestock.

Poisonous Plants on Rangelands: Locoweed and Crazyweed

Locoweed and crazyweed are found throughout South Dakota rangelands, and both can cause livestock poisoning.The names locoweed and crazyweed are often used interchangeably. However, there are notable differences between the species.

Poisonous Plants on Rangelands: Larkspur and Poisonvetch

Larkspurs are the second leading cause for all livestock deaths from toxic plant poisoning. Poisonvetches are considered accumulator plants that uptake excessive levels of selenium and cause toxicity problems in cattle.

Prussic Acid Precautions

During periods of drought, it is important to aware of the factors that can be a concern during these conditions, specifically nitrates and prussic acid. It is important to take precautions when using feeds that could contain one or both compounds.

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.

Managing Orphaned Calves

With careful management and proper nutrition, calves orphaned by challenging winter weather can perform similar to calves still on the cow.
