Cold Weather Feedyard Management

Cold Weather Feedyard Management
Mark J. Venner, Beef Enterprise Consultant, Land O’ Lakes Farmland Feed
The winters of 1998 and 1999 have spoiled us with excellent weather (and performance), however December 2000 has had days that remind us what terms like wind-chill and blizzard are. While we can not change the weather, we can implement some management and production techniques that increase cattle comfort and keep cost of gain figures from increasing.
Many environmental factors influence nutrient requirements and the subsequent performance of cattle. The most important variable is temperature, however wind, snow, rain and mud also cause winter stress. Cold is an obvious stress factor that increases an animal’s demand for energy. As this demand for energy (maintenance) increases more feed is used for heat and less is available for gain.

Grazier: Defining stocking rate and stock density

Grazier: Defining stocking rate and stock density
Jim Gerrish,
American Cowman
I’ve found that a number of cattlemen and other livestock producers really don’t understand the difference between stocking rate and stock density. Some tend to use the terms interchangeably, though they’re actually two very different concepts, with very different effects on the pasture-livestock system.
Simply put, stocking rate is the basic relationship between livestock and the forage resource. It’s the number of animals on the entire grazing unit for the entire grazing season. Think of stocking rate in terms of either animals per acre or liveweight per acre. If we have 100 acres and 100 yearling steers weighing 700 lbs., the stocking rate is one steer/acre or 700 lbs. liveweight/acre.

Grains Are Higher; What About Livestock?

Grains Are Higher; What About Livestock?
Troy Marshall
Beef Magazine
Corn continues to be the ingredient everyone is watching. The latest price run-up in corn has many people talking about a new all-time high. Of course, wheat and soybean prices also have been exploding.
While the decision is primarily between corn and soybeans in the Corn Belt area, the decision on the fringes of corn country is between corn and wheat. In many cases, wheat and soybeans look like a more profitable alternative right now.

Cow Calf: Steps To Proper Heifer Development

Cow Calf: Steps To Proper Heifer Development
Follow these steps for proper heifer development:
1.    At weaning, select the oldest heifers that are closest to their target weight. Select at least 20% more heifers than are needed, which will allow you to cull and replace heifers that do not perform during development.

Oklahoma soil has wide range of nutrient needs

Oklahoma soil has wide range of nutrient needs
By Joe Benton
News Star
If there was a simple $10 add-on that could be purchased at the parts store, installed in less than 30 minutes with a tool as simple as a screwdriver and would guarantee an improvement in the fuel efficiency of your cars, trucks and tractors, for as long as three years, would you do it?

Soil testing is a similar scenario; it takes less than 30 minutes to collect a good sample, one trip to town to deliver it to the Extension Office, it costs $10, a soil probe is about as simple as a screwdriver and it will guarantee an improvement in crop production efficiency for up to three years before it needs to be done again. Whether you are growing forages, a garden, lawn or flowers, determining plant nutrient needs is essential to the health of what you are growing.

Cattle Health: Hit Them Where It Hurts, Effective Fly Control

Cattle Health: Hit Them Where It Hurts, Effective Fly Control
Effective pest control takes into account an insect’s life cycle, how mobile it is, how it eats, and what it feeds on. These key characteristics are different for each of the flies that beef producers have to deal with. Proper identification of problem flies is the first step in selecting appropriate management strategies — and avoiding spending money on products or practices that have little chance of working.

Using Ionophores in Replacement Heifer Diets

Using Ionophores in Replacement Heifer Diets
Dr. Glenn Selk, Extension Cattle Specialist, Oklahoma State University
In an effort to insure more replacement heifers are bred to calve early in their first calving season, ranchers should consider using a supplement containing an ionophore in the growing diet of the heifers. “Ionophore” is the generalized name for the feed additives monensin (Rumensin) and lasalocid (Bovatec). Both are presently approved for use with growing programs for replacement heifers.
Research conducted in Texas and Wyoming indicated that growing heifers fed 200 mg monensin per head per day reached puberty at an earlier age than did similar heifers fed similar diets containing no monensin. Similar data is available for lasalocid.
