Animal Welfare--Animal Rights: Role Of Grazing, Roy Burris Oct 2009

Animal Welfare--Animal Rights: Role Of Grazing, Roy Burris

Kentucky Grazing Conference

The care and handling of farm animals has drawn a lot of media attention lately. Some well-publicized events have given our industry the proverbial black-eye and led to a chain of events that has left livestock producers feeling very vulnerable to negative attacks. Although these events have been very isolated, they have had some very farreaching effects. Could they have been prevented? How? What do we do now?


Extended Grazing And Reduced Stored Feed, Edward N. Ballard Oct 2009

Extended Grazing And Reduced Stored Feed, Edward N. Ballard

Kentucky Grazing Conference

Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation. Typically the cost of supplying nutrients to ruminant livestock is much greater using harvested feedstuffs as opposed to grazing pastures or crop residues. The primary function of a grassland farm is to convert solar energy to marketable livestock products in the most efficient manner. The fewer steps between the animal product and …


Stored Feed Needs: How Much? What Quality?, Jeff Lehmkuhler Oct 2009

Stored Feed Needs: How Much? What Quality?, Jeff Lehmkuhler

Kentucky Grazing Conference

Feed resources are the largest variable expense in beef production systems outside the initial investment in the livestock. When we look at Standardized Performance Analysis (SPA) information from Texas and Minnesota, states that are at the extreme from an environment stance, the projected costs for maintaining a beef cow are strikingly similar. It is important to note that these costs include all expenses and opportunity costs. Getting back to the SPA information, in 2007 the annual cost to maintain a cow in Texas was determined to be roughly $590 while the Minnesota value was near $610 or only about $20/cow …


Tall Fescue Grazing Research, Glen Aiken Oct 2009

Tall Fescue Grazing Research, Glen Aiken

Kentucky Grazing Conference

‘Kentucky-31’ tall fescue, like it or hate it, covers 5 million acres of Kentucky and if you do not have it on your farm, it is likely that one of your bordering neighbors does! Tall fescue owes its persistence and productivity in large part to a fungal endophyte that infects most plants. This endophyte produces an array of alkaloids that benefit the plant in tolerating heat, drought, and grazing. Unfortunately, the endophyte also produces ergot alkaloids that can cause “fescue toxicosis” in cattle. Cattle inflicted with toxicosis have reduced dry matter intake, elevated body temperature, and often retain their winter …


Weed Control Options For Pastures, Jon Doran Oct 2009

Weed Control Options For Pastures, Jon Doran

Kentucky Grazing Conference

What is a weed? A pasture or hayfield “weed” is any plant that you deem as being out of place and/or a plant that is decreasing your desired forage production. Weeds may be classified in several ways including broadleaf weeds, woody plants, and undesirable grasses. Besides decreasing forage, weeds can also interfere with forage utilization, grazing distribution, etc. There are several methods available to control weeds and increase production of and access to desirable forages. The three main methods are cultural, mechanical, and chemical. The cultural method is quite simple-a thriving grass stand is an excellent form of weed control …


Our Experiences With Eastern Gamagrass, Tommy R. Yankey Oct 2009

Our Experiences With Eastern Gamagrass, Tommy R. Yankey

Kentucky Grazing Conference

As livestock producers try to reduce their cost of production, many look at ways to reduce their feed costs. Feed costs have been identified as the largest single cost of livestock production, making up 50 to 70% of the total cost of production. Grazing is the cheapest way to feed cattle on a cost per pound of nutrient basis.


New Developments In Grazing Species And Varieties, S. Ray Smith Oct 2009

New Developments In Grazing Species And Varieties, S. Ray Smith

Kentucky Grazing Conference

During the last 10 years there have been several new forage species that have emerged as useful in grazing systems and many new varieties have been released of traditional species. Plant breeders continue to make improvement in our traditional pasture species like tall fescue, orchardgrass, and red and white clover. In the following paragraphs, I will focus more on some of the forage species that you may not be as familiar with and highlight the advancements occurring in developing new varieties for grazing. There are many sources of information on this subject. I especially encourage you to read the new …


Why Should I Improve My Grazing Program?, Garry D. Lacefield Oct 2009

Why Should I Improve My Grazing Program?, Garry D. Lacefield

Kentucky Grazing Conference

Grazing represents the cheapest way to feed ruminants on a cost per pound of nutrient basis. Stored feed is usually the single largest item in livestock budgets and cost or amount of stored feed is usually the best prediction of potential profitability in most beef cattle operations.
