LSU Master's Theses
This research was conducted to determine the effects of pre-incubation warming on the hatchability of post-peak egg production broiler breeder eggs. An experiment with six trials was conducted with 7,920 freshly laid eggs from Ross 308 and 708 broiler breeders from 61-67-wks of age. For each trial, 1,320 eggs were used to determine if pre-incubation warming treatments of 0, 2, 4, and 6, or 0, 3, 6, and 9, or 0, 9, 12 and 15 hrs (at 37.6°C) could improve the hatchability of eggs stored (at 15.5°C) for three days. After a storage period of three days, the eggs were …
The Utilization Of Red Blood Cells In Diets For Swine And Poultry, Emily Dawn Frugé
The Utilization Of Red Blood Cells In Diets For Swine And Poultry, Emily Dawn Frugé
LSU Master's Theses
The purpose of this research was to determine if increasing levels of RBC would affect growth performance and carcass characteristics of finishing pigs and growth performance of broilers. Three experiments were conducted to determine the effect of incremental levels of red blood cells (RBC; 0 to 4% and 0 to 2%), and thus increasing levels of dietary Leu on growth performance and linear carcass measurements of finishing pigs. Our results suggest that feeding 3 or 4% RBC causes a decrease in growth performance. However, feeding 1 or 2% RBC in the diets of finishing pigs had no detrimental effects on …

Maternal Corticosterone Influences On Fear Responses In Offspring Of Quail Divergent Stress Response Lines, Kyndal A. Davis
Maternal Corticosterone Influences On Fear Responses In Offspring Of Quail Divergent Stress Response Lines, Kyndal A. Davis
LSU Master's Theses
Increased fearfulness has been associated with adrenocortical activation. Maternal corticosterone (B) treatment increases egg yolk B, and elevated B in ovo enhances chick avoidance of humans. Quail selected for exaggerated (high stress, HS) as opposed to reduced (low stress, LS) plasma B response to stress are more fearful, and more B is found in the egg yolks of HS than LS hens. Therefore, the underlying fearfulness (tonic immobility, TI) and timidity (hole-in-the-wall box, HWB, emergence) responses were assessed in chicks hatched from eggs of LS and HS hens implanted with silastic tubes containing no B (CON) or B (B-IMPLANT) during …

Forty-eight calves (heifers n=20, bulls n=28) were randomly assigned one of four dietary treatments which included no additive (C); the yeast culture Saccharomyces cerevisiae (YC); the probiotics Bacillus lichenformis and Bacillus subtilis (P); and both yeast culture and probiotics (YCP). Calves were administered treatments from day 2 to 56 in starter and from day 57 to 84 in grower diets. Body weights were measured at birth and weekly thereafter until day 112 of age. Wither and hip heights were measured weekly. Feed intake, water intake, and fecal scores were recorded twice daily until day 56. Rumen fluid was collected on …
Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt
Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt
LSU Master's Theses
Unstressed and stressed quail hens selected for exaggerated (HS, high stress) rather than reduced (LS, low stress) plasma corticosterone (B) response to brief restraint deposit more B into their eggs than do their LS hen counterparts. HS hens implanted with B also show reduced egg lay when compared to LS- and HS-control and LS-B-implanted hens. Herein, the effects of stress line on length of egg incubation (LEI) and chick body weight at emergence (BWTE) (Exp. 1) and the interactive influences of line with maternal B-treatment (sub-Q control, CON-, or B-implants) on LEI (Exp. 2) and on egg fertility (FERT), total …

Examination Of Crayfish Biodiversity And Distribution Within The Grand River, Michigan, Norrissa M. Thomas, Daniel A. Bergman
Student Summer Scholars Manuscripts
Invertebrates make up a large part of the world's biological diversity and perform essential ecological functions. Many invertebrates are under threat of extinction due to extreme transformations of habitats. Crayfish are one such threatened invertebrate. Crayfish are keystone species in many freshwater systems. Keystone species are those species most important in shaping the ecology of a system. Crayfish are an important resource for many animals and affect species diversity and abundance. Specifically, crayfish can adversely affect ecosystems by removing plants, making the water turbid. They also prey on fish eggs reducing their numbers. There are 415 species of crayfish in …
The Impact Of Biofuel Production On The Western Australian Livestock Industry, Wim Burggraaf, Anne Wilkins
The Impact Of Biofuel Production On The Western Australian Livestock Industry, Wim Burggraaf, Anne Wilkins
Bulletins 4000 -
The Western Australian biofuels industry is in its infancy. There is currently only one small commercial biodiesel manufacturer in the State but there have been several announcements of new biofuel projects in 2006 that will be commercialised by 2010. The projected growth of a new biofuels industry in Western Australia (WA), will create greater competition with other industries that rely on grain as an input in their enterprises. Intensive livestock industries such as beef cattle lot feeding, pig rearing, fattening lambs, growing poultry for meat and eggs and feeding dairy cows depend on a consistent supply of high quality whole …

Muscleworms, Parelaphostrongylus Andersoni (Nematoda: Protostrongylidae), Discovered In Columbia White-Tailed Deer From Oregon And Washington: Implications For Biogeography And Host Associations, Ingrid M. Asmundsson, Jack A. Mortenson, Eric P. Hoberg
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (Odocoileus virginianus). Host and geographic distribution for this parasite, however, remain poorly defined in the region of western North America. Fecal samples collected from Columbia white-tailed deer (O. v. leucurus) in a restricted range endemic to Oregon and Washington, USA, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. Multilocus DNA sequence data (internal transcribed spacer 2 and cytochrome c oxidase subunit 1) established the identity and a new record for P. andersoni in a subspecies of white-tailed deer previously unrecognized as hosts. Populations of …

Deer–Vehicle Collision Statistics And Mitigation Information: Online Sources, Terry A. Messmer, Destiny R. Messmer
Human–Wildlife Interactions
Although good data are lacking, published estimates suggest that >1.5 million deer– vehicle collisions (DVCs) occur annually in the United States. The estimated losses exceed 1 billion dollars. In some states, DVCs are a major cause of reportable accidents. Federal, state, and private partners have cooperated in monitoring trends in DVCs and implementing mitigation measures. Most of this information about such measures is readily available via the Internet. The purpose of this paper is to provide the reader with a broad overview of and a guide to the information currently available online to mitigate DVCs.

Assessment Of Costs Associated With Deer–Vehicle Collisions: Human Death And Injury, Vehicle Damage, And Deer Loss, John A. Bissonette, Christine A. Kassar, Lawrence J. Cook
Human–Wildlife Interactions
Collisions between large vertebrates and vehicles along roadways are an increasing concern, not only because of ecological consequences, but also because of associated economic and social costs. We used a large-scale, long-term data set comprising several databases from Utah to summarize and analyze these costs. The overall cost for 13,020 collisions from 1996 to 2001 in Utah was approximately $45,175,454, resulting in an estimated average per year cost of about $7,529,242 and a mean collision cost of $3,470. These figures include human fatality costs of $24 million (53% of total costs); vehicle damage costs of $18 million (39%); loss of …

Locations Of Deer–Vehicle Collisions Are Unrelated To Traffic Volume Or Posted Speed Limit, John A. Bissonette, Christine A. Kassar
Human–Wildlife Interactions
Consensus is lacking regarding the influence of vehicle speed and traffic volume on deer–vehicle collision (DVC) rates. Yet, annual average daily traffic fl ow (AADT) and posted speed limit (PSL) typically are used to measure these variables. To resolve this conflict, we studied the effects of traffic volume and vehicle speed on DVCs in Utah. Our results showed no relationship between AADT or PSL and DVC occurrence. There are at least 3 explanations for our results: (1) no causal relationship exists; (2) AADT and PSL, as measured, actually explain little of the variation; and (3) data quality problems exist. We …

Mammalian Hazards At Small Airports In Indiana: Impact Of Perimeter Fencing, Travis L. Devault, Jacob E. Kubel, David J. Glista, Olin E. Rhodes Jr.
Human–Wildlife Interactions
Fences are used at many airports and small airfields to exclude wildlife from entering critical areas. However, not all fences exclude hazardous mammals reliably, and effective fences can be too expensive for small airports to purchase and maintain. In this study, we evaluated fencing at 10 small airports in Indiana and documented the presence and relative abundance of wildlife within airport boundaries using remote cameras and spotlight surveys. Only 4 airports were completely fenced, and four were Odocoileusvirginianus) or coyotes (Canis latrans) at nine of the airports with remote cameras and during spotlight surveys. There were …

Evaluation Of An Oral Vaccination Program To Control Raccoon Rabies In A Suburbanized Landscape, Jason R. Boulanger, Laura L. Bigler, Paul D. Curtis, Donald H. Lein, Arthur J. Lembo Jr.
Human–Wildlife Interactions
We evaluated the efficacy of an oral rabies vaccination (ORV) program conducted in Erie County, New York, from July through September, 2002–2005. Ingress of the raccoon (Procyon lotor) rabies variant first occurred along the southern border of Erie County, New York, during 1992 and began to spread northward at a velocity of 31 km/year. Fixed-wing aircraft dropped ORV baits in rural landscapes; helicopters, hand baiting, and bait stations distributed baits in suburban landscapes (x̄ bait densities ranged 59–118 baits/km2). Our study objectives were to quantify rabies case densities, evaluate efficacy of intervention efforts, and determine biological, …

Human–Wildlife Interactions
Rapid development and urbanization of the lower Florida Keys in the last 30 years has fragmented the habitat of the Lower Keys marsh rabbit (Sylvilagus palustris hefneri), hereafter called marsh rabbit, and threatened it with extinction. On the Naval Air Station–Key West (NAS), Boca Chica Key, marsh rabbits exist as a meta-population of discrete habitat patches in a matrix of wetlands and airfield facilities. Airfield safety regulations require NAS to maintain vegetation below a minimum height on runway peripheries (clear zones). We developed a spatially-explicit, stage-structured, stochastic matrix model using the programs RAMAS-Metapop and ArcGIS. Model parameters were …

Deer–Vehicle Collision Trends At A Suburban Immunocontraception Site, Allen T. Rutberg, Ricky E. Naugle
Human–Wildlife Interactions
Observations of extended estrus seasons in female white-tailed deer (Odocoileus virginianus) vaccinated with porcine zona pellucida (PZP) immunocontraceptives have led to speculation that management use of PZP would, perversely, increase the rate of deer–vehicle collisions. To test this hypothesis, we studied PZP-treated female deer at the National Institute of Standards and Technology, Gaithersburg, Maryland. PZP-treated female deer did not differ from untreated female deer in risk of death by vehicle collision, and the number of deer killed in vehicle collisions was uncorrelated with the number of deer treated with PZP, whether or not population size was controlled for. …

Volatile Compounds From The Integument Of White Leghorn Chickens (Gallus Gallus Domesticus L.): Candidate Attractants Of Ornithophilic Mosquito Species, Ulrich R. Bernier, Sandra A. Allan, Brian Quinn, Daniel Kline, Donald Barnard, Gary Clark
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Candidate kairomones of ornithophilic mosquito species are reported from GC/MS analysis of compounds from the skin on the back, the feet, and feathers from the back of White Leghorn chickens (Gallus gallus domesticus). Hexane and ether extracts of chicken feathers differ significantly in attractiveness of Culex spp. mosquitoes. The active (hexane) extracts contained an abundance of alcohols, ketones, and diones. The inactive (ether) extracts contained aldehydes, which also were in the hexane extracts. Analysis of hexane extracts from chicken feet, skin, and feathers demonstrated the qualitative similarity in the compounds collected with subtle differences observed in the quantitative …

The Use Of Extractable Lipofuscin For Age Determination Of Crustaceans: Reply To Sheehy (2008), H. Rodger Harvey, David H. Secor, Se-Jong Ju
OES Faculty Publications
The heterogeneous mixture of metabolic by-products termed lipofuscin (LF) or age pigments has long been known to accumulate in post mitotic cells with increasing age. In crustaceans several approaches have been developed over the years to track LF accumulation and provide a proxy for chronological age. Histological approaches have been traditionally used for LF determination of crustaceans (e.g. Sheehy et al. 1994, Mar Biol 121:237-245), but over the last decade extraction approaches for neural tissues have been introduced (Ju et al. 1999, Mar Ecol Prog Ser 185:171-179) and tested (Ju et al. 2001, Mar Ecol Prog Ser 224:197-205; 2003, Fish …
