Fescue Foot
By Barry Whitworth, DVM
Since most ranchers experienced drought conditions and with fall fast approaching, producers with fescue pastures should closely observe their livestock for any signs of fescue toxicity. According to Mike Trammel, Pottawatomie County Ag Educator and Muti-County Agronomist, fescue toxins (ergot alkaloids) tend to increase in Kentucky-31 tall fescue pastures in the fall. Some reports indicate more problems with fescue toxins following a summer drought and limited fall rains. All of this may put cattle at a greater risk of fescue toxicity.
One issue that cattle experience with fescue toxins is fescue foot. Fescue foot is thought to be caused by ergot alkaloids such as ergovaline. These alkaloids are produced by endophyte fungus (Epichloë coenophiala) which is in tall fescue. Ergovaline has been proven to be a vasoconstrictor which might be responsible for fescue foot and heat intolerance also known as summer slump in cattle. Other issues that may be seen with the ergot fescue toxins are reduced milk production and reproductive issues.

Goats Get To Work
One of my professors out at Texas Tech University always told us that we aren’t just raising cattle, we’re raising grass, because without grass there is no cattle business. The same applies to most livestock species and crops we seek to raise- without good land management, no good yield can grow.

Acorn Toxicity
By Barry Whitworth, DVM, MPH
With the prolonged drought, most pastures in Oklahoma end up in poor condition. With the lack of available forage, animals may go in search of alternative foods.
If oak trees are in the pastures, acorns may be a favorite meal for some livestock in the fall. This may result in oak poisoning.
Oak leaves, twigs, buds, and acorns may be toxic to some animals when consumed.

Silver Bluestems
By: Tony Dean
There are a handful of grasses on North Texas grazing lands ranchers need to know, not because they are highly desirable, but rather because they are not of much value. I call them “decom” plants, which is am acronym for “Don’t Ever Count On Me.” Silver bluestem is a “decom” grass.
Silver bluestem is a perennial which grows in all areas of Texas. It can survive in almost all soil types, and in full sun conditions or in semi shade. It grows up to three feet tall and is easily recognized with the presence of the white fuzzy seed head. Also, one of the identifying characteristics of Silver bluestem is a bend in the stems at each node, causing the plants to take on a rounded shape as they mature.
