    4-H Skills for Life Animal Science Series. Horsing Around: Horse/Horseless Project Activity Guide

    This project activity guide is for boys and girls who may or may not have a horse or pony of their own. The important thing is that they want to learn about horses. If they don't have a horse, some of the activities may help them decide whether they really want to raise or learn more about horses.

    Advancements in Forage Management: Grazing Horses on Cover Crops and Exploring Hand-Held NIRS Technology
    (2021-06) Prigge, Jessica
    Forages are an important part of the equine diet. Although many Midwestern pastures are comprised of cool season grasses and legumes, annual cover crops can help extend the grazing season to offset the reliance on preserved forages like hay. Therefore, the objectives of the first study were to determine forage mass, forage nutrient composition, and preference of cover crops grazed by horses. Forage nutrient composition of fresh or preserved forages is important when balancing horse rations. Near infrared reflectance spectroscopy is a reliable laboratory analysis tool and has rapidly been developed for in-field use. However, nutrient prediction equations are species specific and forages such as alfalfa have not been analyzed in the field. Thus, the objectives of the second study were to develop and validate nutrient prediction equations for fresh alfalfa using a hand-held near infrared reflectance spectroscopy unit in the field.

    Aliens and Animals: Notes on Literary Lifeforms After Darwin and Freud
    (2019-12) Rowe, Michael
    This dissertation examines the work of early twentieth-century English and American writers publishing in the aftermath of war, rapid modernization, and newly urgent questions of social control and management. More specifically, it looks at writers whose work was inflected by a reading of Charles Darwin and/or Sigmund Freud. The writings of Darwin and Freud created new possibilities for reconsidering the relationship of human beings and nonhuman animals. Closely attending to the “presence” of nonhuman figures in the works of Jack London, D.H. Lawrence, H.P. Lovecraft, and Djuna Barnes, this dissertation argues that each writer, with the exception of Barnes, presumes there is a way, via the figure of the animal, to escape or see outside human culture. In the case of Jack London’s John Barleycorn, his memoir on drinking that is also an extended argument for sobriety and Prohibition, London’s image of a draft horse ultimately indicates the impossibility of any kind of sobriety. In London’s imagination, each individual subject is governed by an object—language, imagination, or legal authority—that they ingest to become what they are or could be. D.H. Lawrence’s novella, St. Mawr, likewise uses the figure of a horse, though his stallion suggests that the inexplicability of instinctual animal life—the impossibility of knowing an animal’s interior states of feeling and being—shows a way forward for human beings caught up in the melodrama of “personality.” In the end, Lawrence reaffirms masculine power and the subjugation of women. While H.P. Lovecraft’s short story, “The Whisperer in Darkness” indicates that nonhuman presence can make itself known by failing to “show up,” so to speak, in representational language, his tale recapitulates a fantasy of imperial dominion. His aliens turn out to be human after all. Djuna Barnes’s story, “A Night Among the Horses,” tells a different tale, one in which there is no getting outside human culture. The worlds depicted in London, Lawrence, and Lovecraft accept a binary of “nonhuman” nature and human culture that Barnes throws into question. If the figure of the animal provides an escape hatch, Barnes shows that the hatch leads back inside.

    Methods of restricting forage intake in horses
    (2014-05) Glunk, Emily Clare
    Horses have evolved to be hindgut fermenters, requiring small amounts of forage to be consumed throughout the day [1]. However, due to the recent increase in equine obesity [2-4], it has become necessary to restrict the amount of feedstuffs a horse consumes, often resulting in a restriction of forage intakes. In order to maintain a healthy gastrointestinal system, management strategies should attempt to replicate a horse's natural foraging habits. The objectives of the following studies were: 1) to investigate the effectiveness of decreasing pasture forage intakes via use of a grazing muzzle, and whether the effectiveness could be altered by grass morphology and palatability, 2) to investigate the effectiveness of "slow-feed hay nets" at increasing time to consumption of a preserved forage meal in stalled horses and 3) to observe the effects of increased time to consumption of daily rations on the post-prandial metabolic response. To determine objective 1, a two-year study was designed where four horses were used in a Latin square design in Year 1, while 3 horses were used in a completely randomized design in Year 2. Horses were grazed for 4 hours on monoculture plots four days per month for four months. Initial herbage mass and residual herbage mass measurements were taken to determine forage intakes. For objective 2, 8 horses were used in a replicated Latin square design, with 2 horses assigned to a treatment at a time. There was a control (C) of feeding hay on the ground, as well as three treatments: small-opening net (SN), medium-opening net (MN) and large-opening net (LN). Horses were allowed 4 h to consume their hay meal. Time to consumption and dry matter intake rate were measured using a stopwatch and any orts remaining after the 4 h were collected and weighed. To estimate objective 3, 8 overweight horses were enrolled in a randomized complete block design. Horses were blocked by bodyweight, BCS, and gender. Horses were fed a control diet of hay at 2% BW for a period of 10 days, and were then switched to a restricted diet of hay fed at 1.08% and ration balancer fed once daily at a rate of 0.001% BW. Horses were assigned to one of two treatments: hay fed off the floor (FLOOR) and hay fed in a small-opening hay net (HN). Serial 24 h blood samples were taken on day 0, when horses were still on baseline diet, as well as days 14 and 28. Plasma glucose, insulin, cortisol, and leptin values were estimated.Results of objective 1 found that grazing muzzles were effective at decreasing pasture intakes by 30% (P < 0.0001). Species had no effect on intakes in Year 1 (P = 0.27), but did impact intakes in Year 2 (P = 0.042). Results of objective 2 found that SN and MN were effective at increasing total time to consumption (P < 0.0001) compared to horses on the control and LN, more closely mimicking a horses' natural foraging behavior. Results of objective 3 found that hay nets decreased overall stress of horses on a restricted diet (P < 0.05), however length of sampling and weight loss had a larger impact on post-prandial metabolite. Horses on day 28 of the trial had higher average glucose, insulin and cortisol values, as well as lower AUC cortisol. Increasing time to consumption of forages is a healthy method of decreasing body weight while maintaining healthy post-prandial metabolite values.
