Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins
Human–Wildlife Interactions
Texas harbors the largest population of feral hogs (Sus scrofa) in the United States, with populations estimated at >2 million. Depending on one’s perspective, feral hogs are either a pariah (from the farmer’s standpoint) or a popular sporting animal (from a hunter’s standpoint). As feral hogs increase in range and density, conflicts among stakeholders are sure to increase. Texas Cooperative Extension (TCE) initiated educational programs in 1991 to address concerns regarding the presence and management of feral hogs. Since that time, we have developed various workshops, symposia, and educational materials (e.g., print, videotape, and website) as means of …

Range Size, Habitat Use, And Dial Activity Of Feral Hogs On Reclaimed Surface-Mined Lands In East Texas, Robert C. Mersinger, Nova J. Silvy
Human–Wildlife Interactions
During the last decade, surface lignite mines in eastern Texas have experienced damage by feral hogs (Sus scrofa) to reclaimed areas. Specifically, feral hogs have caused damage to plants used in reclamation. In addition to vegetative losses, erosion control problems and water quality impacts have been noted. Big Brown Lignite Mine in Freestone County, Texas, had tried to control feral hogs through year-long trapping, which proved expensive. We hypothesized that hogs were using reclaimed areas only at night and seasonally. If so, knowledge of travel lanes into the mine and seasonal use would help concentrate trapping efforts and …

Influence Of Habitat Patch Characteristics On The Success Of Upland Duck Nests, Jaime E. Jiménez, Michael R. Conover, Raymond D. Dueser, Terry A. Messmer
Human–Wildlife Interactions
When there is a rich guild of nest predators that use different modalities and techniques to locate hidden nests, we hypothesized that no habitat patch characteristic will consistently predict nest success, because if such a characteristic existed then predators would develop a search image based on it and use that characteristic to increase their hunting efficiency for nests. We tested this prediction in the Prairie Pothole region of North Dakota by characterizing the features of 16 habitat patches that contained >1,800 dabbling duck nests. Nest success was monitored during both the early and late nesting season over 2 years. Nest …

Human–Wildlife Interactions
Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …

Hazing Of Canada Geese Is Unlikely To Reduce Nuisance Populations In Urban And Suburban Communities, Robin A. Holevinski, Paul D. Curtis, Richard A. Malecki
Hazing Of Canada Geese Is Unlikely To Reduce Nuisance Populations In Urban And Suburban Communities, Robin A. Holevinski, Paul D. Curtis, Richard A. Malecki
Human–Wildlife Interactions
Growing populations of resident Canada geese (Branta canadensis) have caused increased nuisance problems in urban and suburban communities. Hazing, or persistent harassment, is often recommended as a nonlethal management strategy to alleviate these problems. Does hazing simply cause a local redistribution of birds, or can it solve nuisance problems by pushing geese to rural areas where hunting mortality could reduce the population? To answer this question, we marked 368 adult and 400 juvenile geese with leg bands in 1 urban and 1 suburban community in western New York State during June 2002 and 2003. This sample included 30 …

Status Of Birds Newly Recorded In Arkansas Since 1985, Douglas A. James, Joseph C. Neal, Max Parker, Charles Mills
Journal of the Arkansas Academy of Science
In 1994 we published an annotated list of 14 bird species that were newly discovered in Arkansas since the publication in 1986 of the monograph "Arkansas Birds, Their Distribution and Abundance." We now add 22 more new species found in Arkansas since the 1994 publication, and update the status of the original 14. Adding these 36 species to the number included in "Arkansas Birds" totals 402 bird species currently reported in Arkansas.

Turkish Journal of Veterinary & Animal Sciences
Avian influenza virus stocks (A/chicken/Iran/259/1998/(H9N2)) were propagated in the allantoic cavities of 10-day-old embryonated chicken eggs. The harvested suspension was concentrated by polyethylene glycol 6000. Concentrated samples were layered onto sucrose gradient (30%-60%). Both hemagglutinin and neuraminidase were solubilized from purified viruses with Triton X-100 across 30% sucrose gradient. NA was isolated from HA and other viral proteins by affinity chromatography on N-(p-aminophenyl)oxamic acid. Fractions that had high NA activity and did not show HA activity were pooled and analyzed by neuraminidase inhibition and SDS-PAGE. No viral protein bands were detected, except for a single band in the position of …

Turkish Journal of Veterinary & Animal Sciences
In this study, 130 Escherichia coli strains isolated from 306 cattle and sheep fecal samples were studied for their resistance to 10 antibiotics, verotoxin production, and hemolyzation. The antibiotic resistance rates of the E. coli strains were as follows: tetracycline, 51.6%; streptomycin, 24.2%; ampicillin, 13.1%; amoxicillin/clavulanic acid, 5.2%; gentamycin, 4.6%; ciprofloxacin, 4.6%; trimethoprim-sulfamethoxazole, 4.3%; cefotaxime, 0.7%. None of the strains were resistant to cefepime or ceftazidime. Of all the antibiotics tested, only resistance to streptomycin was higher in the strains isolated from cattle than in the sheep strains (P = 0.043). The evaluation of the cattle strains, based on gender …

Microscopic and macroscopic structures of accessory adrenal nodules in Caspian miniature horses (5 males and 5 females) were studied. The accessory adrenal nodules were round or oval and yellow to red. Their maximum diameters varied from 0.1 to 0.5 cm. These nodules were found near the kidneys and adrenal glands, but they were in close contact with the adrenal gland. The accessory adrenal nodules were similar to the adrenal cortex microscopically, and from the outer layer to the inner layer they contained glomerulosa, intermedia, and fasciculata. The adrenal nodules were surrounded by a capsule of collagenous dense connective tissue as …
Effect Of Feeding Supplemental Tallow On The Performance Of Lactating Nili-Ravi Buffaloes, Haq Nawaz, Muhammad Yaqoob, Muhammad Abdullah
Effect Of Feeding Supplemental Tallow On The Performance Of Lactating Nili-Ravi Buffaloes, Haq Nawaz, Muhammad Yaqoob, Muhammad Abdullah
Turkish Journal of Veterinary & Animal Sciences
In order to determine the feeding value of tallow for lactating Nili-Ravi buffaloes, 4 buffaloes were fed 0%, 2%, 4%, or 6% tallow in a 4 X 4 Latin square experiment. The intakes of dry matter (DM), organic matter (OM), crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) decreased (P < 0.01), but the intakes of ether extract (EE) (P < 0.01) and digestible energy (DE) (P < 0.05) increased with increasing levels of tallow in the diets. Intake of net energy for lactation (NE_L) did not differ (P < 0.01) with varying levels of supplemental tallow. Daily milk yield increased (P < 0.01) from 11.00 to 13.2 kg/day. Production of 4% fat corrected milk (FCM), solid corrected milk (SCM), and energy corrected milk (ECM) increased quadratically (P < 0.05) with the increasing level of tallow in the diets. Milk fat content and total milk fat increased linearly (P < 0.01) and quadratically (P < 0.05), respectively, as the level of tallow in the diet increased. There was no difference in protein and lactose content due to feeding tallow. Total solid content increased quadratically (P < 0.05) from 16.45% to 17.67% but solid not fat (SNF) percentages did not vary with varying levels of tallow. The gross energy (GE) of the milk increased from 1096 to 1160 Kcal/kg (P < 0.01) with increasing levels of tallow in the diets. Energetic efficiency of milk production improved in a quadratic (P < 0.05) manner with 2%, 4%, and 6% tallow, with the highest being 47.6% with 4% supplemental tallow. The proportion of C_{8:0} to C_{16:1} fatty acids (FA) decreased from 53.66% to 35.52%, whereas the concentration of C_{18:0} to C_{20:0} increased (44.93% to 62.84%) in the milk fat of buffaloes fed diets containing different levels of tallow. Gains in body weight (BW) were higher (P < 0.05) in buffaloes fed diets containing supplemental tallow as compared to those fed the control diet. This study suggests that tallow up to 6% of diet DM is a suitable fat supplement as an economical energy source for lactating buffaloes.

Turkish Journal of Veterinary & Animal Sciences
In a 12-week feeding trial, the effect of 2 algae meals (Ulva rigida or Cystoseira barbata) on feed intake, growth, and nutrient utilization of juvenile Nile tilapia, Oreochromis niloticus, was investigated. This was the first attempt to utilize Cystoseira barbata as a feed supplement for Nile tilapia. The fish were fed to apparent satiation with formulated diets supplemented with various levels of Ulva meal (5%, 10%, or 15%) or Cystoseira meal (5%, 10%, or 15%). A diet without algae meal served as a control diet. The highest values for weight gain were for fish fed the 5% Cystoseira diet, control …

Overabundant populations of Canada geese (Branta canadensis) cause economic and safety concerns associated with collisions with civil and military aircraft. Habitat management techniques that reduce the use of airfield habitats by geese might reduce these concerns. The objective of this study was to determine if captive Canada geese exhibited a foraging preference between a vegetation mixture consisting mostly of perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) versus an endophyte-infected tall fescue- (Festuca arundinacea) based vegetation mixture. We established 6 paired plots of perennial ryegrass-dominated and tall fescue-dominated mixtures at NASA …
Cryopreservation Of White-Tail Deer Epididymal Sperm For Artificial Insemination, Jesse Ray Saenz
Cryopreservation Of White-Tail Deer Epididymal Sperm For Artificial Insemination, Jesse Ray Saenz
LSU Master's Theses
The ability to cryopreserve epididymal sperm from mature postmortem bucks has long been of interest to both wildlife conservationists and deer ranchers. Increased understanding of the cryobiology of epididymal sperm from a non domestic species, such as White-tail deer, could aid in development of future protocols to assist in the preservation of endangered species. In Experiment I, results showed that after cooling postmortem bull testes for 22 hours, no significant difference was noted between sperm parameters of epididymal sperm collected at room temperature or at a cool enviorment. In Experiment II, it was shown that White-tail deer sperm could be …
Reproductive And Metabolic Effects Of Recombinant Equine Leptin On Seasonally Anovulatory Mares, Pamela Boliew Mitcham
Reproductive And Metabolic Effects Of Recombinant Equine Leptin On Seasonally Anovulatory Mares, Pamela Boliew Mitcham
LSU Master's Theses
Mares of poor body condition have low plasma leptin concentrations, while obese mares have the highest concentrations. Leptin is a primary signal of body condition to the brain in other species; therefore, low leptin concentrations in thin mares could contribute to their extended anovulatory period in winter compared to obese mares. The current experiment was designed to determine whether recombinant equine leptin, administered to seasonally anovulatory mares, would induce ovarian activity and ovulation in the winter. Leptin effects on metabolism were also studied. Beginning January 7, leptin-treated mares (n = 9) received daily i.m. injections of 10 mg recombinant equine …
