Hay for Horses: Alfalfa Or Grass?
HAY FOR HORSES: ALFALFA OR GRASS? Anne Rodiek1 ABSTRACT Alfalfa hay is an excellent source of energy, protein, calcium and some other nutrients for horses. Its concentrations of protein and calcium meet the nutrient needs of horses in high levels of production, such as growth and lactation, but exceed the nutrient requirements of horses in other life stages. Controversy exists over the best use of alfalfa in horse rations. Grass hays are also popular for horses because of their lower energy, protein and calcium concentrations. Grass hay meets more closely the nutrient requirements of the largest percentage of horses, the idle horse. Tradition plays a large role in the selection of feeds for horses. Hay producers can help educate horse people about what hays are most beneficial to horses in different life stages. Key Words: alfalfa hay, grass hay, horses, nutrient requirements INTRODUCTION Alfalfa hay has been both heralded and maligned as a feed for horses. Tradition holds that timothy hay and oats are the best feeds for horses, and that alfalfa and corn spell disaster. Alfalfa hay may not be the best feed for all horses in all situations, but it contains nutrients needed for many classes of horses. Grass hay falls short of meeting the nutrient requirements of high production life stages, but is an excellent filler for horses that require bulk in the diet. An understanding of the nutrient requirements of horses compared to the nutrient content of alfalfa hay or grass hay will help nutritionists, hay producers, and horse owners make informed decisions about what type of hay to feed to horses. -

What About Hay?
Small Ruminant Series What About Hay? by Dr. Rick Machen Associate Professor & Extension Livestock Specialist Texas Agric ultural Exte nsio n Service, Uvalde Rumina nts ( goats, cattle, sheep, deer, ante lope, elk, bison, etc.) are, by desi gn, grazi ng animals. Their rumen, the largest gastrointestinal compartment, is an environment wherein bacteria anaerobically ferment (digest) forages. This unique digestive process converts solar energy captured by plants into higher quality, more nutrient dense foods like milk and meat. Compared to harvest by a grazing animal, hay production is an expensive process, involving fossi l fuel, mac hinery and man- hours. Haying als o involves si gnificant s oil nutri ent relocation when compared to grazing. Protein ( nitrogen) and minerals harveste d and hauled off the soil of a hay meadow or field must be replaced if optimal hay production is to be maintained. Grazing, on the other hand, is part of a natural cycle. A portion of the nitrogen and minerals from the consumed forage is returned to the soil with urine and feces. So, whether it s feeding beef cows on the open range or goats in a small paddock, hay is not a supplement - it is a substitute. A s ubstitute for the s tanding forage or browse that makes up the diet of a ruminant animal in their natural habitat. As shown in the Table 1, the typical diet of a foraging goat ranges from !S to ½ browse and ½ to !S grass, depending upon season and availability of the respective forages. Goats are opportunistic grazers and will select a diversity of plants to result in the highest attai nable diet quality. -

1 Degradation in Mongolia's Gobi Desert: Not As Straight Forward As
Degradation in Mongolia’s Gobi Desert: not as straight forward as assumed J. Addison A,B . M. Friedel A. C. Brown C. J. Davies A. S. Waldron A. A c /o CSIRO Ecosystem Sciences, PO Box 2111, Alice Springs, NT, 0871, Australia B Corresponding author: [email protected] C School of Agriculture and Food Science, University of Queensland, St Lucia, Qld, 4067, Australia Short title: How applicable are degradation assumptions to Mongolia’s Gobi Desert? Abstract Assumptions about the levels and causes of rangeland degradation in Mongolia have become embedded amongst a range of stakeholders. This paper explores the applicability of five such widely-held assumptions about rangeland degradation in Mongolia to the more specific case of the rangelands of the Gobi Desert. These assumptions are: i) there are too many animals; ii) goats have proportionally increased and this is causing desertification; iii) rainfall is declining; iv) there is less pasture now; and v) Mongolian rangelands are degraded. Biophysical and quantitative social data from the Dundgobi and Omnogobi desert-steppe areas suggest not all of these assumptions are supported mechanistically all of the time, and that the information upon which these assumptions are based is more complex than is commonly recognised. Caution in designing policy and programmes based on current understandings of rangeland condition is necessary. 1 Additional keywords : rangeland, Gobi Desert, livestock, goats, climate Introduction Rangeland theory and the understanding of causal mechanisms behind rangeland dynamics have changed significantly over the last century. The largely static ‘climax community’ of Clementsian succession (Clements 1916) has been replaced by ideas of more dynamic multiple stable and non-equilibrium states (Holling 1973; Noy-Meir 1975), thresholds (Friedel 1991), and states and transitions models (Westoby et al . -
Soil Gaseous Emissions and Partial C and N Balances of Small-Scale Farmer Fields in a River Oasis of Western Mongolia

Such intensification triggers substantial gaseous carbon (C) and nitrogen (N) losses that may aggravate disequilibria in the soil surface balances of agricultural plots. This study aims to quantify such losses, and assess the implications of these emissions against the background of calculated partial C and N balances. To this end, CO2, NH3, and N2O soil emissions from carrot, hay, and rye plots were measured by a portable dynamic closed chamber system connected to a photoacoustic multi-gas analyzer in six farms of the Mongolian river oasis Bulgan sum center. Average C and N flux rates 1 1 1 1 1 1 1 1 (1313 g CO2-C ha− h− to 1774 g CO2-C ha− h− ; 2.4 g NH3-N ha− h− to 3.3 g NH3-N ha− h− ; 1 1 1 1 1 1 0.7 g N2O-N ha− h− to 1.1 g N2O-N ha− h− ) and cumulative emissions (3506 kg C ha− season− 1 1 1 1 1 1 to 4514 kg C ha− season− ; 7.4 kg N ha− season− to 10.9 kg N ha− season− ) were relatively low compared to those of other agroecosystems, but represented a substantial pathway of losses (86% of total C inputs; 21% of total N inputs). -

Switchgrass: a Bioenergy Crop Profile for West Virginia
Switchgrass A Bioenergy Crop Profile for West Virginia What is Switchgrass (Panicum virgatum) is a hardy, tall-growing, deep-rooted perennial switchgrass? grass native to North America east of the Rocky Mountains. It is a warm sea- son grass, which means it grows in the warm months of the year until frost, and is dormant in winter and early spring. Warm season grasses typically take longer to establish than their cool-season counterparts, but once established, they tend to live much longer with less maintenance. As a perennial species, switchgrass can be harvested annually for approximately twenty years. What are the Switchgrass is a promising bioenergy crop for several reasons. Switchgrass uses of can be harvested as biomass annually and used as feedstock for biofuel produc- tion. It can be converted to ethanol for use as a transportation fuel, or it can switchgrass? be pelletized and burned for heat production. In addition, it can be used as livestock forage and wildlife cover. As switchgrass grows, it pulls carbon from the atmosphere for developing its deep and dense root structures. If properly measured and reported, this carbon sequestration can be traded as carbon credits to offset industrial carbon emissions. Is switchgrass West Virginia has up to 150,000 acres of reclaimed and soon-to-be reclaimed well suited to surface mine sites that are potentially available for conversion to production of bioenergy crops. High yields of switchgrass can be achieved with minimal fer- WV’s marginal tilizers or other agricultural inputs even on WV’s marginal soils like these re- soils and re- claimed mine lands. -

Hay Is for Horses
Hay is for Horses BY KAREN E. DAVISON, PH .D. Record droughts or heavy rainfall, it seems like most of the country is experiencing one or the other. In some areas, it has been a year of record drought followed now by heavy rainfall. One major impact extreme weather may have on horse owners is availability and/or quality of hay and pasture. Since the bulk of a horse’s diet is hay or pasture, any change in the nutritional content of the forage affects the nutritional status of the horse. How do you evaluate the nutritional content of your hay? Good quality hay, regardless of variety, will have the following characteristics: 1) a high leaf to stem ratio, 2) small diameter stems, 3) a fresh smell, 4) free from weeds, dirt, mold and other trash, 5) bright color, 6) few seed heads (grasses) or blooms (alfalfa). In addition, hay should be fairly soft and pliable to touch. If stems are hard and stick into your hand when you grab a handful, then you might imagine how chewing that hay would feel. While visual appraisal of hay can provide an indication of quality, laboratory analysis is really the most accurate measure of the nutritive value. There is hay that looks pretty good but doesn’t test well and if you feed it the same as more nutrient dense hay, your horses will lose weight. If you buy several small quantities of hay through the year, testing may not be much help because you will probably feed most of the hay before the test results come back.
