Can We Graze 300+ Days?, Glen Aiken
Can We Graze 300+ Days?, Glen Aiken
Kentucky Grazing Conference
Dependence on stored feeds during the winter months has been necessary in order to maintain body condition and meet nutrient requirements of cattle herds; unfortunately, cost of stored feeds typically are a major part of the farm budget. We know, all too well, that hay shortages and unstable feed ingredient markets have reduced profit potential in cattle production. This has further placed higher demands on supplies of co-product feeds to cause prices of these alternative feeds to rise and make them less cost effective. There will likely be less reliance on concentrate and co-product feeds as the forage-based livestock industry …
Pastures For Horses, Robert Coleman
Pastures For Horses, Robert Coleman
Kentucky Grazing Conference
The horse evolved as a grazing animal. In order to consume enough forage to meet the horses’ nutritional needs a significant amount of time would be spent each day grazing. The pattern of selecting forage-moving to the next area starting to graze again can easily translate into 14 to 16 hours of grazing activity each day. The level of grazing activity will also be affected by the available forage and the daily access to pasture.
Pastures For Goats And Sheep, Greg Brann
Pastures For Goats And Sheep, Greg Brann
Kentucky Grazing Conference
Pasture for sheep is not that different than that for cattle but pasture for goats is very different. Sheep are grazers like cattle whereas goats are browsers like deer. Even though grass and clover are not a goats preference if all of the forage present is grass and clover goats will eat it. Due to goats and sheep being more prey animals than cattle they don’t like to wade off into tall vegetation, also it takes more energy for them to move through tall growth. Many plants that we traditionally consider weeds become desirable forbs when goats or sheep are …
The Role Of Weed Control In Profitable Pastures, Scott Flynn, Pat Burch
The Role Of Weed Control In Profitable Pastures, Scott Flynn, Pat Burch
Kentucky Grazing Conference
Pasture weeds compete for resources such as space, water, and nutrients. This competition reduces forage yield which in turn reduces the carrying capacity of a pasture. Although herbicide applications are needed to gain a quick upper hand on weed control most producers are deterred due to cost, the potential loss of pasture legumes, labor, or the belief that herbicide applications are required frequently to keep weed population under control. However, herbicide use in pastures should not be looked at in this manner but instead as an investment that can pay for itself very quickly and easily, and be long-term especially …
Role Of Legumes In Pastures, Garry D. Lacefield
Role Of Legumes In Pastures, Garry D. Lacefield
Kentucky Grazing Conference
Successful livestock production is dependent on forage programs which supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy (61%) cattle come from forages. In addition, forages supply an estimated 91%, 72%, 15% and 99% of the nutrients consumed by sheep and goats, horses, swine and ruminant wildlife, respectively.
(How I Think About) Kentucky's Pastures: One Of Kentucky's Untapped Resources, Jimmy C. Henning
(How I Think About) Kentucky's Pastures: One Of Kentucky's Untapped Resources, Jimmy C. Henning
Kentucky Grazing Conference
One of the privileges of old(er) age is the prerogative to take liberties with assigned tasks. At the risk of confusing producers and offending more scientifically-current forage scientists, the topic of pasture as an untapped resource presented an opportunity to address task from an unexpected angle. Certainly, Kentucky’s pastures are a resource with untapped potential. But the idea that their value as a resource depends on how we think about them is one worth pursuing.

Second generation feedstocks for bioethanol will likely include a sizable proportion of perennial C4 grasses, principally in the Panicoideae clade. The Panicoideae contain agronomically important annual grasses including Zea mays L. (maize), Sorghum bicolor (L.) Moench (sorghum), and Saccharum officinarum L. (sugar cane) as well as promising second generation perennial feedstocks including Miscanthus × giganteus and Panicum virgatum L. (switchgrass). The underlying complexity of these polyploid grass genomes is a major limitation for their direct manipulation and thus driving a need for rapidly cycling comparative model. Setaria viridis (green millet) is a rapid cycling C4 panicoid grass with a relatively …

Finishing Beef On Alfalfa, Todd Powell
Finishing Beef On Alfalfa, Todd Powell
Kentucky Alfalfa and Stored Forage Conference
Powell Farms started in 1996 with 15 acres of Alfalfa hay intended for cow/calf feed. A neighbor and his friends bought every bale that year. Over the next 14 years the only alfalfa hay our cows got to eat was when a cutting got wet and was rolled. As with any business when the economy starts to take a downward trend, it is wise to start looking for new and innovative ways to market your product.

Fertilizer: How Much Is In Each Bale?, Dennis Hancock
Fertilizer: How Much Is In Each Bale?, Dennis Hancock
Kentucky Alfalfa and Stored Forage Conference
What do you see when you look at a bale? Certainly, many would say it is a source of feed for our livestock. Others see a commodity that is sold to their customers. These are the most important aspects of any forage. But, there is one other intrinsic value worth noting… its nutrient content. In a sense, it is a bale of fertilizer.
Our Experience With Roundup Ready Alfalfa, Clayton Geralds
Our Experience With Roundup Ready Alfalfa, Clayton Geralds
Kentucky Alfalfa and Stored Forage Conference
We raise approximately 500 acres of alfalfa with approximately 175 seeded to Roundup Ready varieties. We established our first field in 2006 and a second in 2007. Roundup Ready alfalfa was not available for additional seedings until 2011. We have seeded over 100 additional acres in 2011 and 2012.
Key To Success When Harvesting Alfalfa As Baleage, S. Ray Smith
Key To Success When Harvesting Alfalfa As Baleage, S. Ray Smith
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is an excellent forage for high-producing cows and universally considered one of the highest-quality forages. Cows efficiently use the high levels of protein, calcium and high-quality fiber in alfalfa for producing milk and meat. The palatability of alfalfa is high, especially when the leaves are maintained during harvest. Typically, cows will eat more alfalfa than grass because the fiber content is usually lower in alfalfa. Harvesting alfalfa as baleage vs. hay greatly improves the chances maintaining high quality because there is less leaf loss and less loss of soluble carbohydrates. The most important factor is harvesting high quality alfalfa …

The purpose of natural treatment systems is the re-establishment of disturbed ecosystems and their sustainability for benefits to human and nature. The working of natural treatment systems on ecological principles and their sustainability in terms of low cost, low energy consumption, and low mechanical technology is highly desirable. The current review presents pros and cons of the natural treatment systems, their performance, and recent developments to use them in the treatment of various types of wastewaters. Fast population growth and economic pressure in some developing countries compel the implementation of principles of natural treatment to protect natural environment. The employment …
Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer
Factors Influencing The Establishment And Survival Of Native Hardwood Tree Seedlings Of The Kentucky Inner Bluegrass Blue Ash-Oak Savanna-Woodland, James D. Shaffer
Theses and Dissertations--Biology
Historically, the Kentucky Inner Bluegrass blue ash-oak savanna-woodland was the primary ecosystem of the Inner Bluegrass Region (IBR) of Kentucky. After European settlement, the majority (>99%) of Bluegrass savanna was converted to agricultural and urban land uses. Currently remnant savanna tree species are failing to recruit. Therefore, a long-term restoration ecology project researching competition and disturbance on seedling establishment, survival, and growth has been established at Griffith Woods (the largest remaining savanna in Kentucky) in Harrison Co., KY. Fourteen native hardwood tree species (a total of 6,168 seedlings) have been experimentally planted. Light, soil, surrounding vegetation, and herbivory, factors …
Transformations, Bioavailability And Toxicity Of Manufactured Zno Nanomaterials In Wastewter, Sewwandi Rathnayake
Transformations, Bioavailability And Toxicity Of Manufactured Zno Nanomaterials In Wastewter, Sewwandi Rathnayake
Theses and Dissertations--Plant and Soil Sciences
In order to properly evaluate the ecological and human health risks of ZnO Manufactured nanomaterials (MNMs) released to the environment, it is critical to understand the likely transformation products in the wastewater treatment process and in soils receiving biosolids. To address this critical knowledge gap, we examined the transformation reactions of 30 nm ZnO MNMs in single component and multi-component systems, with phosphate and natural organic matter (NOM). We also assessed the influence of nano ZnO transformation on the bioavailability, and toxicity of ZnO transformation products to Triticum aestivum. The data revealed that ZnO MNMs react with phosphate at …
Managing Soil Microbial Communities With Organic Amendments To Promote Soil Aggregate Formation And Plant Health, Shawn T. Lucas
Managing Soil Microbial Communities With Organic Amendments To Promote Soil Aggregate Formation And Plant Health, Shawn T. Lucas
Theses and Dissertations--Plant and Soil Sciences
The effects of managing soil with organic amendments were examined with respect to soil microbial community dynamics, macroaggregate formation, and plant physio-genetic responses. The objective was to examine the possibility of managing soil microbial communities via soil management, such that the microbial community would provide agronomic benefits. In part one of this research, effects of three amendments (hairy vetch residue, manure, compost) on soil chemical and microbial properties were examined relative to formation of large macroaggregates in three different soils. Vetch and manure promoted fungal proliferation (measured via two biomarkers: fatty acid methyl ester 18:2ω6c and ergosterol) and also stimulated …
Evaluating The Sustainability Of Four Organic Vegetable Production Systems, Delia W. Scott
Evaluating The Sustainability Of Four Organic Vegetable Production Systems, Delia W. Scott
Theses and Dissertations--Plant and Soil Sciences
A field study evaluating the sustainability of four organic vegetable production systems was conducted in Lexington, Kentucky in 2006 and 2007. The four systems included no-till, raised beds covered with biodegradable black mulch, bare ground with shallow cultivation, and bare ground with shallow cultivation and wood chip mulch. The two-year study compared yield, weed control, labor, and costs associated with each system, as well as physical, chemical, and microbiological soil characteristics. In 2006, tomatoes (Lycopersicon esculentum Mill.) were grown in the four systems, with no significant difference in yield. Summer squash (Cucurbita pepo L.) was grown in the …
