Utilization Of Corn Residue, Winter Range, Or Dry Lot In Beef Heifer Development Systems, Stetson P. Weber

Department of Animal Science: Dissertations, Theses, and Student Research

Post-weaning heifer development systems that maximize reproductive efficiency and reduce input costs associated with feed is beneficial for cow/calf producers. Two research experiments were conducted to evaluate the effect of post-weaning development systems in beef heifers. In Exp. 1 heifers were developed on corn residue (CR), or dry lot (DL). Heifers developed in DL had increased BW after winter treatment until breeding. Both heifer groups were similar in percent of heifers cycling, AI conception, AI pregnancy, and final pregnancy diagnosis. A subset of AI pregnant heifers were blocked by weight and stratified by winter development system and individually fed using …

Effects Of Feeding Insect-Protected Corn And Corn Residue To Cattle, And Evaluation Of Distillers’ Grains Storage When Mixed With Crop Residue On Cattle Performance, Barry Weber

Department of Animal Science: Dissertations, Theses, and Student Research

Research has been conducted on genetically modified corn fed to livestock since the introduction of insect resistant hybrids. While the overwhelming conclusion of these trials demonstrate nutritional equivalency to corn from non-transgenic hybrids, the introduction of new transgenes and combinations of resistance traits necessitates continued evaluation of genetically modified corn hybrids. Expansion of the ethanol industry has resulted in the increased availability of co-products for use as a livestock feed, as well as an increase in crop residues that offer unique opportunities for use by cattle producers. A finishing trial was conducted with corn and corn silage from MON 89034, …

Effect Of Light Level On Feeding Behavior In A Lemur Species (Eulemur Rubriventer) With A Color Vision Polymorphism., Ainsley Lockhart

Independent Study Project (ISP) Collection

Understanding the visual capabilities and correlated behavior of prosimians provides vital information regarding the evolution of color vision. Feeding behavior in particular is often modified based on color vision status in various primate taxa. The present study examined feeding behavior under various light conditions in Eulemur rubriventer, a lemur species with a color vision polymorphism in which only females can have trichromatic vision. Behavioral observations were conducted for a single E. rubrventer group over a 13 day study period in April 2012. Results found no significant difference in rates of frugivory or exploitation of green vs. non-green food between male …

Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Endangered interior least terns (Sternula antillarum athalassos) and threatened northern Great Plains piping plovers (Charadrius melodus) nest together on midstream sandbars in large rivers in the interior of North America. We investigated the relationship between river channel width and tern and plover nesting incidence on the lower Platte River, Nebraska, using a model-based logistic regression analysis. Multiple channel width measurements and a long-term nesting data set were used in the analysis. Nesting incidence was positively associated with increasing river channel width proximal to the nesting site. At a greater distance, up to 802 m away from …

Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

We evaluated the reproductive biology of314 white-tailed jackrabbits (Lepus townsendii) in 44 counties throughout South Dakota from June 2004 to September 2005. We classified jackrabbits as juveniles or adults based on the closure of the proximal epiphysis of the humerus using X-ray analysis. We determined annual reproductive activity through fluctuations in measured weights of reproductive organs for both sexes. The 2005 breeding season started in late February and proceeded until mid-July, approximately 142 days, allowing for females to potentially produce 3.3 litters. We found four distinct breeding periods by the overlap of estimated conception and parturition dates. Mean …

The Effects Of Dependent Infants On The Social Behavior Of Mantled Howler Monkeys (Alouatta Palliate), Keziah Katz

Honors Theses and Capstones

Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant and other adult monkeys. Males preferred to spend time with females without infants but still spent more time with females with infants than with males. Females without infants spent significantly less time with females with infants than with males or other females without infants and females with infants decreased their frequency of social interaction overall without preference for males, females or other females with infants.

Ethnoknowledge Of Bukusu Community On Livestock Tick Prevention And Control In Bungoma District, Western Kenya, Wycliffe Wanzala, Willem Takken, Wolfgang R. Mukabana, Achola O. Pala, Ahmed Hassanali

All Peer-Reviewed Publications

Ethnopharmacological relevance: To date, nomadic communities in Africa have been the primary focus of ethnoveterinary research. The Bukusu of western Kenya have an interesting history, with nomadic lifestyle in the past before settling down to either arable or mixed arable/pastoral farming systems. Their collective and accumulative ethnoveterinary knowledge is likely to be just as rich and worth documenting. Aim of the study: The aim of the present study was to document indigenous knowledge of the Bukusu on the effect of livestock ticks and ethnopractices associated with their management. It was envisaged that this would provide a basis for further research …

The Origin Of Malarial Parasites In Orangutans, M. Andreína Pacheco, Michael J.C. Reid, Michael A. Schillaci, Carl A. Lowenberger, Biruté M. F. Galdikas, Lisa Jones-Engel, Ananias A. Escalante

Harold W. Manter Laboratory of Parasitology: Library Materials

Background: Recent findings of Plasmodium in African apes have changed our perspectives on the evolution of malarial parasites in hominids. However, phylogenetic analyses of primate malarias are still missing information from Southeast Asian apes. In this study, we report molecular data for a malaria parasite lineage found in orangutans.

Methodology/Principal Findings: We screened twenty-four blood samples from Pongo pygmaeus (Kalimantan, Indonesia) for Plasmodium parasites by PCR. For all the malaria positive orangutan samples, parasite mitochondrial genomes (mtDNA) and two antigens: merozoite surface protein 1 42 kDa (MSP-1₄₂) and circumsporozoite protein gene (CSP) were amplified, cloned, and …

Plant-Soil Feedbacks And Subalpine Fir Facilitation In Aspen-Conifer Forests, Joshua R. Buck

Theses and Dissertations

This thesis includes two studies. The first study examined changes in soil characteristics as a result of prolonged conifer dominance in successional aspen-conifer forests. Changing disturbance patterns in aspen-conifer forests appear to be altering successional dynamics that favors conifer expansion in aspen forests. The primary objective of this paper was to identify how increasing conifer dominance that develops in later successional stages alters forest soil characteristics. Soil measurements were collected along a stand composition gradient: aspen dominated, aspen-conifer mix, conifer dominated and open meadow, which includes the range of conditions that exists through the stages of secondary succession in aspen-conifer …

An Object-Based Image Analysis Of Treated And Untreated Pinyon And Juniper Woodlands Across The Great Basin, April Hulet

Theses and Dissertations

Land managers need to rapidly assess vegetation composition and bare ground to effectively evaluate, manage, and restore shrub steppe communities that have been encroached by pinyon and juniper (P-J) trees. A major part of this process is assessing where to apply mechanical and prescribed fire treatments to reduce fuel loads and maintain or restore sagebrush steppe rangelands. Geospatial technologies, particularly remote sensing, offers an efficient option to assess rangelands across multiple spatial scales while reducing the need for ground-based sampling measurements. High-spatial resolution color-infrared imagery (0.06-m pixels) was acquired for sagebrush steppe communities invaded by P-J trees at five sites …

Cheatgrass (Bromus Tectorum), Native Grasses, And Small Mammals In The Great Basin: A Test Of The Apparent Competition Hypothesis Facilitated By A Novel Method Of Decanting Seeds From A Flotation Solution, Jacob Elias Lucero

Theses and Dissertations

The effect of shared enemies between invasive and native species has been argued to facilitate biological invasions (i.e., the apparent competition hypothesis or ACH). This study investigated a previously untested possibility: whether granivorous small mammals facilitate cheatgrass (Bromus tectorum) invasion by driving food-mediated apparent competition between cheatgrass and native grasses. Specifically, we tested three predictions that must be true if such apparent competition occurs. First, cheatgrass invasion augments total seeds available to granivorous small mammals. Second, density of granivorous small mammals increases in response to increased seed availability (simulated with experimental additions of cheatgrass seeds). Third, granivorous small …

Tool Use In Fishes, Culum Brown

Sentience Collection

Tool use was once considered the sole domain of humans. Over the last 40 years, however, it has become apparent that tool use may be widespread across the animal kingdom. Pioneering studies in primates have shaped the way we think about tool use in animals, but have also lead to a bias both in terms of our expectations about which animals should be capable of using tools and the working definition of tool use. Here I briefly examine tool use in terrestrial animals and consider the constraints of the current working definition of tool use in fishes. Fishes lack grasping …
