Seeps And Springs At A Platteville “Observatory” On The River Bluffs, Bj Bonin, Greg Brick, Julia R. Steenberg Oct 2015

Seeps And Springs At A Platteville “Observatory” On The River Bluffs, Bj Bonin, Greg Brick, Julia R. Steenberg

Sinkhole Conference 2015

Residential building construction along the Mississippi River bluffs in the 1970s created a unique enclosed outcrop of the Late Ordovician Platteville Formation at Lilydale, Minnesota. This outcrop was examined in early 2013 after a newly-formed spring flooded an elevator shaft the previous year, drawing attention to the foundation conditions. The Lexington Riverside property is a six story condominium complex constructed within the top of the bluff. A two-level underground parking garage was built into the bluff. Bedrock was mechanically excavated to accommodate the construction of the building, creating an unweathered rock surface. The space between the structure and the excavated …

Hay Quality: What Is It?, Garry D. Lacefield, Don Ball Feb 2015

Hay Quality: What Is It?, Garry D. Lacefield, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Profitable livestock production almost always requires a forage program that will supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy cattle (61%) 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 wildlife, respectively.


Alfalfa And The Environment, Don Ball Feb 2015

Alfalfa And The Environment, Don Ball

Kentucky Alfalfa and Stored Forage Conference

We live in a society in which many people don’t understand or appreciate agriculture as much as they really should. After all, only about 2% of the population of the United States is involved in agriculture, so most people don’t know much about it. Furthermore, most don’t spend much time thinking about it. Forage crops, including alfalfa, are especially under-appreciated because forage is not consumed directly by humans (alfalfa sprouts being a minor exception).


Red Meat, Our Health And Alfalfa--Separating Scientific Fact From Opinions, Policy, Politics, And Bureaucracy, Peter Ballerstedt Feb 2015

Red Meat, Our Health And Alfalfa--Separating Scientific Fact From Opinions, Policy, Politics, And Bureaucracy, Peter Ballerstedt

Kentucky Alfalfa and Stored Forage Conference

The general public is becoming increasingly aware of the failure of the official nutritional policy of United States and other countries. Books like Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health (Taubes, 2008), Why We Get Fat and What To Do About It (Taubes, 2011) and The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet (Teicholz, 2014) have exposed the disconnect between nutrition science and nutrition policy, and have told the story of how we’ve come to this point in history.


Grazing Alfalfa: Real Cost Of "Fear" Of Bloat, S. Ray Smith, Kenneth H. Burdine, Jeff Lehmkuhler Feb 2015

Grazing Alfalfa: Real Cost Of "Fear" Of Bloat, S. Ray Smith, Kenneth H. Burdine, Jeff Lehmkuhler

Kentucky Alfalfa and Stored Forage Conference

In the Southeast, including legumes like alfalfa and clover in pastures provides many advantages. It reduces the impact of fescue toxicosis, provides free nitrogen, and improves pasture quality leading to increased animal performance. Individual animal performance is greater on grass/legume pastures compared to performance on similar monoculture grass stands. Daily gains for steers grazing clover-fescue swards is improved compared to straight tall fescue pastures (Figure 1). Improved performance is partially due to greater forage intakes. This practice is sound management even though legume bloat is a risk to livestock. If one considers the number of cattle grazing pastures containing legumes …


What's Required To Break The "Beef Per Acre" Kentucky Record, Kenneth R. Johnson Feb 2015

What's Required To Break The "Beef Per Acre" Kentucky Record, Kenneth R. Johnson

Kentucky Alfalfa and Stored Forage Conference

As I approach the task that Garry assigned me, I ask the question, “Do I really want to attempt to produce 1400 or more pounds of beef per acre?” An easy answer is “yes,” but more likely “no.” Most farmers I know, full or part time have all they can do now and to reach record levels of anything requires much more time and management. I am going to attempt to discuss the steps I think that will be required to reach record breaking production. Higher gains are certainly possible. We know alfalfa can produce 8 to 10 tons of …


Alfalfa Is Our Family Farming Operation, Myron Ellis Feb 2015

Alfalfa Is Our Family Farming Operation, Myron Ellis

Kentucky Alfalfa and Stored Forage Conference

Ellis Family Farm is a 5th generation family farm located in Harrodsburg, KY. Currently we farm 1250 acres total of which 870 acres is owned and the remainder is leased. We buy and resale between 1500-1800 head of feeder cattle per year and have 100 head of brood cows. The cattle operation feed is completely supplied by the first cutting of our 580 acres of alfalfa and alfalfa grass mix hay. From the second cutting on, we produce small square bales of alfalfa for the horse market in four states. Our normal production of square bales ranges between 75,000 and …

Wastelands Of The Mind: The Identity Crisis Of India’S Savanna Grasslands, Abi Tamim Vanak Jan 2015

Wastelands Of The Mind: The Identity Crisis Of India’S Savanna Grasslands, Abi Tamim Vanak

IGC Proceedings (1993-2023)

The idea that wastelands are unproductive continues to be pervasive and is used by various agencies to gain control over marginal landscapes and remake them for productive purposes with dire results.


Stakeholders Integration For Sustainable Use Of Temperate Forage/Livestock Agriculture, Garry D. Lacefield, Don Ball Jan 2015

Stakeholders Integration For Sustainable Use Of Temperate Forage/Livestock Agriculture, Garry D. Lacefield, Don Ball

IGC Proceedings (1993-2023)

Forage/livestock production is complex, and best management options are often site-specific, but some concepts have broad application. The intent of this article is to provide an overview of research-based management approaches that the authors believe are necessary to ensure the sustainability of forage/livestock farms. This overview discussion is needed because livestock agriculture is changing, thus creating both challenges and opportunities for producers. In the last 30 years, beef numbers in the USA have declined by 20%, but production per cow has more than doubled, resulting in increased total production on less land with fewer animals. Similar statistics exist for the …


Participatory And Holistic Approaches With Grassland Farmers And Development Of Policies, Alain Peeters Jan 2015

Participatory And Holistic Approaches With Grassland Farmers And Development Of Policies, Alain Peeters

IGC Proceedings (1993-2023)

The world is changing rapidly. Grassland farmers and ruminant livestock breeders will have to adapt to these changing environmental, social and economic conditions. Research can help them at the condition that linear ‘top-down’ technology transfer methods are abandoned for the benefit of participatory and holistic approaches. These approaches classified in the generic term of ‘Farming System Research’ consider farmers as real research partners, and they merge farmer’s and scientist’s ideas with those of other stakeholder types. They combine scientist’s and farmer’s knowledge for creating fast innovations, easily adopted by farmers since farmers themselves contribute to their design and their development. …


Using Various Lactic Acid Bacteria Strains During Forage Conservation Towards Fermentation, Storage, Nutritive Value And Safety Improvement, Jonas Jatkauskas, Vilma Vrotniakiene Jan 2015

Using Various Lactic Acid Bacteria Strains During Forage Conservation Towards Fermentation, Storage, Nutritive Value And Safety Improvement, Jonas Jatkauskas, Vilma Vrotniakiene

IGC Proceedings (1993-2023)

Many research efforts have been devoted to find ways how to produce silages with maximum nutritive value, good fermentation and low mould and yeast counts. While there are different objectives in using silage additives, the main objectives are to improve fermentation and reduce dry matter loss, and to prevent secondary fermentation at feed out time. This paper presents our most significant and recent investigations on forage inoculation before ensiling that have a potential for beneficial application on grassland and ruminant nutrition.


Traditional Livestock Production And Growth Opportunities In India, S. M. Deb Jan 2015

Traditional Livestock Production And Growth Opportunities In India, S. M. Deb

IGC Proceedings (1993-2023)

Livestock and animal health development projects need to be based on an understanding of livestock production systems because different systems need different approaches particularly in view of degradation of environment combined with population pressure. In India, the livestock production system is primarily traditional, consisting of mixed-farming and pastoral systems, therefore, development of marginal and smallholder mixed farms must aim at intensification of the total production system. Resource-poor farming systems may aim at the improved management of the various livestock species in backyards. Pastoral systems must focus on effective management of grazing pressure. Community pasture management involves application of technologies, land …


Problems And Prospects Of Grassland Development: Policy Issues, S. Ray Smith Jan 2015

Problems And Prospects Of Grassland Development: Policy Issues, S. Ray Smith

IGC Proceedings (1993-2023)

There are a range of government and non-government policies that affect grassland development around the world. The objective of this paper is to provide examples of successful policies which have been instrumental in the preservation and maintenance of grasslands and to highlight policies which have resulted in negative consequences. This paper will not attempt to provide a complete overview of policies, but instead will provide examples from representative countries. Policies which affect grasslands can be classified into two broad categories: government policies that cover comprehensive landscape issues like the Grassland Household Contract System (GHCS) in China or the Federal Land …
