Cull cows represent between 15 and 30 percent of a cow-calf herd's revenue, but relatively little attention is given to cull cow marketing. Most cow-calf producers traditionally sort and sell cull cows in the fall when prices are at or near the seasonal low.
When shopping for hay, a list of its features such as crude protein or pounds in a bale may or may not be available, making valuation of hay difficult, if not impossible. This can be easily remedied by asking for a hay analysis and a bale weight, or testing and weighing it yourself prior to purchase.
There has been a great deal of interest over the last several years in the novel or "friendly" endophyte-infected tall fescue varieties. These varieties have the potential to provide quality cool-season perennial forage without the negative attributes of the older toxic endophyte-infected tall fescues.
Many producers in the stocker business have said that the profit is made when the calf is purchased. If correct decisions are made when the calf is bought, then the rest of the job is much easier.
When I was attending the TCU Ranch Management Program in the 1970s, Mr. John Merrill referred to basic facts or truths about production biology as "hitching posts" because they don't change.
Succession is a relatively predictable process of change that occurs in plant communities and soils. It is an important concept when managing native plant communities for wildlife, livestock grazing, timber production or other goals.
Mass spectrometry has managed to creep into the mainstream consciousness - albeit without most people realizing it's even there. Popular television shows like CSI have proliferated images of investigators collecting samples from crime scenes and then analyzing them in the laboratory to understand their chemical makeup. That's analytical chemistry and mass spectrometry. That's Lloyd Sumner's world - without the crime, of course.
To scientists, grass is never just grass. Countless species of plants comprise what the rest of us refer to as grass, some of which - like clover - aren't really grass at all, but pod-bearing legumes. To researchers who study them, grasses and legumes are a diverse and dynamic cornerstone of life and agriculture.
Kelly Craven enjoys the road less traveled. Months after earning his bachelor's degree, Craven placed graduate school on hold and struck out on his own, shaking off the status quo for a little unfamiliar terrain. He bounced from the Bavarian Alps to the Mediterranean on a personal quest of discovery that honed his scientific aspirations and provided him confidence to blaze his own trail.
Yiming Bao discovers more than just research niche at Noble Research Institute, he laid the groundwork for the Noble Research Institute's current cellular imaging facility and played an instrumental role in purchasing the institution's first confocal microscope.
