Utilizing Alfalfa Hay In Horse Diets, Laurie Lawrence

Kentucky Alfalfa and Stored Forage Conference

All horses need fiber in their diets. Forages, usually as pasture or hay, are the primary sources of fiber in most rations. The exact amount of hay that a horse will eat on a daily or yearly basis will depend on the size of the horse, the class of the horse (pregnant, working, etc) and the type of hay being fed. The type and amount of other feeds in the ration will also impact the amount of hay consumed, but in general, horse owners/managers should try to maximize forage intake and then supplement with grain or other feeds to meet …

Grazing Alfalfa: Putting The Puzzle Together, Garry D. Lacefield, Jimmy C. Henning, David Stalion

Kentucky Alfalfa and Stored Forage Conference

Interest in alfalfa as a grazing crop has increased dramatically over the past decade. There are many research and demonstrations being conducted in Kentucky and across the U.S. as we continue to investigate and learn more about alfalfa's role in forage-based livestock production.

Listed below are some of the reasons farmers, researchers and agribusiness personnel are excited about the opportunity for alfalfa as a grazing crop.

Immunofluorescent Localization Of Rubpcase In Degraded C4 Grass Tissue, M. S. Miller, Lowell E. Moser, Steven S. Waller, Terry J. Klopfenstein, B. H. Kirch

Department of Agronomy and Horticulture: Faculty Publications

Digestion-resistant tissues found in C4 grasses may allow soluble protein to escape rumen degradation. The objective of this study was to use immunofluorescent localization to follow loss of ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBPCase) from switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerardii Vitman) parenchyma bundle sheath cells (BSC) during rumen degradation. Fluorescent signal was observed from switchgrass and big bluestem BSC through 24 and 16 h in situ digestion, respectively, and from BSC associated with both intact tissue fragments, and isolated vascular bundles in omasal digesta and fecal material from steers (Bos tarus L.) grazing switchgrass. Immunofluorescent …

Comparative Biologies Of The Cryptic, Sympatric Species, Trupanea Bisetosa And T. Nigricornis (Diptera: Tephritidae) In Southern California, Khouzama M. Knio, Richard D. Goeden, David H. Headrick

Horticulture and Crop Science

The biologies of the sympatric, cryptic species, Trupanea nigricornis (Coquillett), a flower head-infesting fruit fly attacking a wide range of hosts in 8 tribes, 33 genera, and at least 71 species of Asteraceae, and T. bisetosa (Coquillett), an oligophage attacking only 6 hosts in 4 genera of the tribe Heliantheae, are described and compared. A major biological distinction between these species was their ovipositional behavior, whereby females oviposited different numbers of eggs at different sites in different developmental stages of flower heads of their hosts. The larvae of these species showed minor differences in their feeding behaviors, and their puparia …

Genome-Wide High-Resolution Mapping By Recurrent Intermating Using Arabidopsis Thaliana As A Model, Sin-Chieh Liu, Stanley Kowalski, Tien-Hung Lan, Kenneth A. Feldmann, Andrew H. Patterson

Law Faculty Scholarship

We demonstrate a method for developing populations suitable for genome-wide high-resolution genetic linkage mapping, by recurrent intermating among F2 individuals derived from crosses between homozygous parents. Comparison of intermated progenies to F2 and “recombinant inbred” (RI) populations from the same pedigree corroborate theoretical expectations that progenies intermated for four generations harbor about threefold more information for estimating recombination fraction between closely linked markers than either RI-selfed or F2 individuals (which are, in fact, equivalent in this regard) . Although intermated populations are heterozygous, homozygous “intermated recombinant inbred” (IN) populations can readily be generated, combining additional information afforded by intermating with …

Germplasm And Cultivar Development, M. D. Casler, Jeffrey F. Pedersen, G. C. Eizenga, S. D. Stratton

Department of Agronomy and Horticulture: Faculty Publications

Cool-season forage grasses have evolved, and continue to evolve, in natural ecosystems subject to environmental factors both in the presence and absence of human influences. The literature often lacks facts describing the evolution and domestication of forage grasses. Furthermore, the literature on this subject mainly deals with evolution of species in the broad scope, i.e., on a scale of hundreds of thousands or millions or years. Thus, some of our conclusions are necessarily speculative and are highly subject to the nature of the research that has been reported. We describe the forces of selection that act upon cool-season forage grasses …

Development Of House Flies (Diptera: Muscidae) In Sand Containing Varying Amounts Of Manure Solids And Moisture, Jerome Hogsette

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

House flies, Musca domestica L., developed in 200 cm³ of coarse sand containing just 1 ml (0.47%) of dairy manure solids and 10 ml (4.74%) of moisture. At these levels, development was slow (21.5 d from 1st instar to adult), adult survival was low (7.5%), but successful development did occur. At higher manure and moisture levels, rates of development and survival were similar to those reported previously. All soil samples collected from a feedlot dairy contained higher levels of manure solids than the highest level tested in the laboratory. The implications for fly control in soil/manure mixtures and the …

Annual Forages: New Approaches For C-4 Forages, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

The current agricultural paradigm in the U.S. is heavily biased towards the production and marketing of crops as commodities. This paradigm is kept in place by grain handling and marketing infrastructure, as well as government farm programs, designed for crops as commodities. Sorghum (Sorghum bicolor L. Moench) and maize (Zea mays L.) grown for grain certainly fit into this current paradigm.

A new approach to agricultural production and marketing, identity preserved products, is gaining in importance. This is made possible through new technologies and markets demanding products designed specifically for their needs. Examples of investment in identity preserved …

Grasslands: An Introduction, Kathleen H. Keeler

Great Plains Quarterly (through 2013)

"Grasslands" was the subject of the seventeenth annual symposium of the Center for Great Plains Studies, held at the University of Nebraska-Lincoln, in April 1994. Grasslands are so basic to the Great Plains experience as to be invisible. If you stand here in eastern Nebraska, it is so far in any direction across grasslands to any other landscape (a cornfield is a planted grassland, after all) that the role of grasslands in our lives does not seem worth considering. Local variation is much more visible. You can't see the prairie for the grasses, to adapt the idiom. And yet, grasslands …

An Economic Study Of The Relative Profitability Of Alfalfa Production And Marketing Practices, David Claycomb

Masters Theses & Specialist Projects

The seasonality of the price of alfalfa hay in Kentucky was studied as well as the potential cost or profitability of storage of this hay. Economic comparison of alfalfa hay production to other farm enterprises was carried out. In addition, an estimate of the value of two qualities of alfalfa hay was calculated based on 1991 prices. The analysis of 41 years of marketing data demonstrated significant differences (P<.01) in price with seasonal lows in June/July and a steady increase in price to a high in March. In general (based on $100 per ton hay and 12% interest) the alfalfa hay producer could lose from $5 to $10 storing hay and selling at a later date. There were some specific conditions where he might have realized a return to storage of $0.16 to $1.48 per ton. A further evaluation of average (KY Feeder) and good (KY Pride) quality hays indicated that current prices of $70-$75 and $100 per ton respectively were the prices where a dairyman would be able to include this hay in the cow's total diet. Even with problems of quality and quantity of alfalfa hay, the economic returns to the production of alfalfa hay were favorable when compared to other crops in Kentucky with the additional benefit of alfalfa being a crop that can result in reduced soil erosion from sloping land. Returns above variable costs can be from $120 to $400 per acre depending upon yield and sale price. However, an understanding of seasonality of price as well as storage costs need to be considered by alfalfa hay producers to assure realizing the above returns.

Membrane Protein As A Basis Of Nacl Tolerance In Alfalfa, Husni N. Sabah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study sought to determine whether NaCl altered the plasma membrane proteins in alfalfa exhibiting differential NaCl concentrations, and whether CaSO₄ modified the responses. Two alfalfa cultivars, Centurion and Condor, were grown in 0.5 strength Hoagland solution in a greenhouse. The cultivars were exposed to 0, 88, and 132 mM of NaCl alone and mixed with CaSO₄ ⋅ H₂O at 7 and 14 Mm CaSO₄ for 3, 9, and 60 days.

In experiment 1, roots were dried to determine their Na, Ca, K, and Mg concentration. The results were similar to previous reports in which …
