Picking Apples Off The Grazing Tree: How Far Can We Extend The Grazing Season Profitably?, Greg S. Halich Jan 2016

Picking Apples Off The Grazing Tree: How Far Can We Extend The Grazing Season Profitably?, Greg S. Halich

Kentucky Grazing Conference

Will grazing more and feeding less hay always increase profitability? There are many cases where cattle farmers could graze more days profitably. I would guess that more than half the cattlemen in Kentucky and the region could find ways to do so. But the statement is not universally correct and we need to evaluate the specific situation to determine if increasing grazing days will pay off.


Grazing Corn To Maximize Late Summer And Fall Gains, Jeff Lehmkuhler, Eric Vanzant Jan 2016

Grazing Corn To Maximize Late Summer And Fall Gains, Jeff Lehmkuhler, Eric Vanzant

Kentucky Grazing Conference

Corn is a warm-season grass with a growth pattern dependent on temperatures. Warmer temperatures accelerate growth while cooler temperatures slow maturation. Thermal time is often referred to as Growing Degree Days (GGD) and calculated as GGD = ((Max Temp – Min Temp)/2) – 50 when calculating in Fahrenheit (Nielsen, 2012). In the upper transition zone, corn thrives and is the major planted crop. The warmer temperatures of the summer months combined with adequate precipitation allows this crop to be a potentially high yielding crop.


Native Warm-Season Grasses: Naturally Adapted Productive Pastures, Pat Keyser Jan 2016

Native Warm-Season Grasses: Naturally Adapted Productive Pastures, Pat Keyser

Kentucky Grazing Conference

The series of severe droughts between 2007 and 2012 resulted in substantial decreases in cattle numbers – and enterprises – in our region. Some of the impact of these droughts may have been offset if producers in the region had reliable, drought-resilient summer forages. For all of the benefits of tall fescue, it was never meant to provide our summer forage. After all, it is a cool-season grass. What we have been learning about toxicosis in recent years further emphasizes the value of having alternative forages available during summer months.


How Diversity Extends The Grazing Season At Dogwood Farm, Debby Dulworth Jan 2016

How Diversity Extends The Grazing Season At Dogwood Farm, Debby Dulworth

Kentucky Grazing Conference

This article was previously published in Cow Country News.

Cattle are a valuable resource these days, in ways that most people, consumers and producers alike, haven’t yet realized. Putting some other resources into making the change for a better grazing system makes sense, especially here in Kentucky, where grass has, in the past, been the basis of a healthy and expansive economy. Grass can once again be the basis for a healthy economy, if enough people with the vision to see its possibilities get involved and make it happen. A truly healthy economy begins with good human health and …


Putting Some Pop Back In Your Crop: Alfalfa In Crop Rotations, Ben M. Goff Jan 2016

Putting Some Pop Back In Your Crop: Alfalfa In Crop Rotations, Ben M. Goff

Kentucky Grazing Conference

While alfalfa is often recognized as the “Queen of the Forages”, corn may be considered “King of the Crops” and currently ranks as the nation’s largest acreage crop with over 87 million acres. The corn acreage U.S. has continued to increase in recent years for various reasons including greater market demand, a shift towards larger farms that focus on a fewer number of crops, and the development of improved varieties and management practices. According to the U.S. Census of Agriculture, the acreage devoted to corn and soybeans has risen by 64 and 255%, respectively, over the last 30 years, while …


Reduced Or Low Lignin Alfalfa: Advantages For Hay And Grazing, S. Ray Smith Jan 2016

Reduced Or Low Lignin Alfalfa: Advantages For Hay And Grazing, S. Ray Smith

Kentucky Grazing Conference

Lignin is an essential structural component of all land plants. It fills spaces in the cell wall between cellulose, hemicellulose, and pectin. Lignin provides the strength to plants from giant Sequoia trees to alfalfa growing in hay fields. A good analogy is that lignin is like the steel reinforcing rods in concrete. Life on earth would not be possible without lignin to allow plants to grow upright. The limitation for livestock is that lignin is indigestible. Forage breeders have long realized that the quickest way to improve forage quality would be to reduce lignin concentration, but if lignin is reduced …


Grazing Alfalfa: Producer Perspective, Bob Hall Jan 2016

Grazing Alfalfa: Producer Perspective, Bob Hall

Kentucky Grazing Conference

Scott County native Robert (Bob) Hall, Jr. is a man of many hats. He and his wife Bonnie have embarked on many ventures on their farm including sheep, hogs and tobacco. Hall was born and raised on the farm outside of Georgetown, where he currently resides and operates a stocker operation. Some may recognize Hall for the feed mill he purchased in the 1960’s known as Hallway Feeds. Early in the Mill’s history over 90 percent of their sales were to dairy producers. Now 95 percent of company’s sales go to the equine industry. Hallway Feed is sold and distributed …


'Lacefield Maxqll' Novel Tall Fescue, Timothy D. Phillips Jan 2016

'Lacefield Maxqll' Novel Tall Fescue, Timothy D. Phillips

Kentucky Grazing Conference

The goal of deploying novel endophyte strains in tall fescue varieties has been to achieve forage yields, stress tolerance, and persistence similar to toxic endophyte tall fescue varieties (mainly ‘Kentucky 31’ endophyte infected with the common toxic endophyte strain), but with the superior animal performance results seen with endophyte-free tall fescue varieties or other non-toxic forage species (orchardgrass, alfalfa, etc.). In addition to better stand persistence, less weed encroachment has been reported in novel endophyte (and toxic endophyte) tall fescue varieties compared to their endophyte-free versions (Rudgers et al., 2010; Bouton et al., 2002). The improved competitive ability of endophyte-containing …


Soy Hulls: More Than Just A Feed Supplement, Glen E. Aiken, Michael Flythe Jan 2016

Soy Hulls: More Than Just A Feed Supplement, Glen E. Aiken, Michael Flythe

Kentucky Grazing Conference

There is approximately 35 million acres of tall fescue in the USA, with most of this acreage being utilized in hay meadows and grazed pastures in a region between the temperate northeast and subtropical southeast and commonly referred to as the Fescue Belt. Popularity of the grass is due to its productivity, persistence, and low cost of management. Unfortunately, a fungal endophyte that infects most plants of tall fescue produces ergot alkaloid toxins that cause a toxicosis in cattle and other grazing livestock. Fescue toxicosis may reduce reproductive performance of cow herds and weaning weights, and reduce post-weaning weight gain …


The Secret Ingredients Of Clover: Biochanin A And Isoflavonoids, Michael Flythe, Glen Aiken, Isabelle Kagan Jan 2016

The Secret Ingredients Of Clover: Biochanin A And Isoflavonoids, Michael Flythe, Glen Aiken, Isabelle Kagan

Kentucky Grazing Conference

It is well known that the value of clover is in nitrogen. Clovers fix their own nitrogen so that an input of nitrate fertilizer is not required. Furthermore, they are rich in protein-nitrogen, and can be used to meet the protein requirements of ruminants. Clovers also contain a class of chemicals called isoflavones, and we have recently discovered evidence that the isoflavones positively influence the way that ruminants digest protein.
