Turkish Journal of Veterinary & Animal Sciences

In this study, 20 neonatal diarrhoeic and 10 clinically healthy neonatal calves were used. Venous blood samples were collected from each animal to determine platelet numbers, pH, partial pressure of carbon dioxide (pCO_{2}), partial pressure of oxygen (pO_{2}), saturated oxygen (O_{2}SAT), content of carbon dioxide (ctCO_{2}), actual bicarbonate (HCO_{3}act), standard bicarbonate (HCO_{3}std), and actual base excess (actBE) of plasma. Plasma samples were collected from each animal for the measurement of prothrombin time (PT), thromboplastin time (aPTT), thrombin time (TT), and the concentrations of fibrinogen and cross-linked fibrinogen degradation products (D-dimer). Blood pH, HCO_{3}act, HCO_{3}std, actBE, ctCO_{2}, and O_{2}SAT values were …

Comparison Of Polymerase Chain Reaction And Conventional Methods For The Diagnosis Of Listeria Monocytogenes In Stuffed Mussels, Ergün Ö. Göksoy, Şükrü Kirkan, Osman Kaya

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to evaluate the role of stuffed mussel as a source of Listeria monocytogenes. Polymerase chain reaction is a rapid procedure with both sensitivity and specificity for quick detection and identification of L. monocytogenes. A total of 50 mussel samples were investigated for L. monocytogenes. L. monocytogenes was not identified by the conventional method. However, PCR amplification products demonstrated that 5 out of 50 samples showed positive reactions with L. monocytogenes. The PCR positive samples showed specific amplification at approximately 343 bp for L. monocytogenes.

The Effect Of A Condensed Tannin Containing Forage, Sericea Lespedeza On Existing And Challenge Infections Of Haemonchus Contortus In Sheep, Leigh Ann Chafton

LSU Master's Theses

Haemonchus contortus is one of the most threatening parasites to small ruminant production. Control has traditionally relied on the use of anthelmintics. Control has waned because the worm population has developed resistance to most of the currently available anthelmintics and alternative control measures are needed. Current consumer pressure is to reduce the use of chemicals in agricultural products, thus pushing control methods to more natural and acceptable approaches. One such approach is the feeding of condensed tannin containing forages either as fresh forage or dried products (hay, meal, pellets, etc). This study was conducted to determine the effect of a …

Cryopreservation And Intracytoplasmic Sperm Injection With Bovine Epididymal Spermatozoa, Carlos Andres Guerrero

LSU Doctoral Dissertations

Recently, interest in the preservation of epididymal sperm as a potential source of valuable genes for genome resource banks has escalated. The development of a successful protocol to recover and cryopreserve sperm harvested from the epididymides would salvage germplasm from genetically valuable males that are injured and can no longer mate or have unexpectedly died and can be used as a model for the preservation of male gametes from endangered species. In a series of experiments, epididymal sperm was successfully harvested, cryopreserved and used for intracytoplasmic sperm injection. In Experiment I, ethylene glycol was found to cause significantly (P<0.05) less osmotic damage to bovine sperm during a one step addition and/or removal at 4°C as compared with glycerol in all concentrations evaluated. Furthermore, prolonged exposure (5 days at 4°C) of ethylene glycol was found to be less toxic than glycerol to sperm. In Experiment II, it was demonstrated that glycerol was more effective than ethylene glycol in providing protection against freezing injury during the cryopreservation process in the concentrations evaluated. In Experiment III, it was demonstrated that epididymal sperm retrieval using seminal plasma is beneficial to enhance sperm overall and progressive motility characteristics and to protect it from morphological abnormalities derived from the freezing process. In Experiment IV, a one step dilution process for removal of glycerol from cryopreserved epididymal sperm was found to significantly affect plasma membrane integrity and mitochondrial function of sperm previously exposed to seminal plasma. However, seminal plasma exposure did not have any significant detrimental effect on acrosome integrity. Furthermore, it was demonstrated that the longevity and survivability in vitro during a 4-hour incubation period at 37°C of post-thaw epididymal sperm exposed to seminal plasma prior to cryopreservation was not compromised when compared with the control extended sperm. In Experiment V, we have demonstrated that fertilization, blastocyst and fetal development could be achieved with cryopreserved bovine epididymal sperm by intracytoplasmic sperm injection (ICSI). To our knowledge, this is the first report in the United States and second in the world to use bovine epididymal sperm for ICSI. We achieved far markedly improved blastocyst rates over those results recently reported in the first study originating in Japan.

Comparing Bermudagrass And Bahiagrass Cultivars At Different Stages Of Harvest For Dry Matter Yield And Nutrient Content, Ryan Thomas Dore'

LSU Master's Theses

Rapid growth of warm-season grasses such as bermudagrass (Cynodon dactylon) and bahiagrass (Paspalum notatum) is associated with a decline in their nutritional value. This study was initiated to provide production and composition data with different cultivars of bermudagrass (common, Russell, Jiggs) and bahiagrass (Tifton-9, Pensacola, Argentina). Dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) composition and production were evaluated every two weeks for a ten-week period on six different cultivars. Also, Russell bermudagrass was evaluated in a second trial very similar to the first trial for composition and production but was started …

The Effects Of Micronutrients On Pullets And Broilers, Danielle Armantine Lauzon

LSU Master's Theses

Two experiments were conducted to determine the availability of various vitamin E (E) sources (absorbed to verxite or adsorbed to silica) in broilers. In Experiment 1, at 100 and 300 IU supplemental E, an average of 94 and 44% of E intake from verxite and silica, respectively, was excreted in the feces, but at 30 IU E, 49 and 45% of E intake was excreted in the feces. In Experiment 2 at 30 IU, 52 and 43% of E intake from verxite and silica was excreted (source, P < 0.02). Based on these results, E adsorbed to silica is more available. Two experiments were conducted to determine the relative bioavailability of organic versus inorganic sources of either Mn or Zn. In Experiment 1, Mn as MnSO4 or a Mn amino acid complex (Availa-Mn) were compared. In Experiment 2, ZnSO4 or a Zn amino acid complex (Availa-Zn) were compared. The results indicate that Availa-Mn is a more available source of Mn than MnSO4, but Availa-Zn is not as available as a source of Zn as ZnSO4. An experiment was conducted to determine the effects of organic sources of Zn, Mn, and Cu on White Leghorn pullet performance. Treatment diets consisted of a control diet with 66 ppm Zn as ZnSO4 or a combination of ZnSO4 and Availa-Zn, 66ppm Mn as MnSO4 or a combination of MnSO4 and Availa-Mn, and 10 ppm Cu as CuSO4 or a combination of CuSO4 and a Cu amino acid complex (Availa-Cu). Diets are inorganic sources (IO), organic Zn (OZ), organic Zn and Mn (OZM), or organic Zn, Mn, and Cu (OZMC). Addition of OZM increased (P < 0.08) intestinal tensile strength and increased (P < 0.06) grams of ash per bone compared with OZMC. Pullets fed OZ had a higher (P < 0.08) bone concentration of all minerals than pullets fed OZM. Total tibia Mn was decreased (P < 0.06) by OZMC, but total tibia Cu was increased (P < 0.08) by OZ addition over IO or OZM.

Physical And Health Assessment Of A Population Of Raccoon (Procyon Lotor) In Northeastern Florida, Eric C. Munscher

UNF Graduate Theses and Dissertations

The purpose of this research was to study the potential negative effects that mesopredators have on their environment and to promote control of mesopredator populations. Overabundant predatory species such as the raccoons (Procyon lotor) and Virginia opossums (Didelphis virginiana) can have significant pernicious effects on populations of autochthonous prey species, particularly when super predators such as the red wolf (Canis rufus) and Florida panther (Felis concolor coryii) are absent. These overabundant species, coined as mesopredators, are often responsible for extreme levels of predation on prey species and/or their young. The mesopredator release hypothesis involves the "release" or increased density of …

This project was developed in two phases: pre-experimental and experimental. In the first phase, genetic material appropriate for the project and the initial rations for consumption was acquired. The second phase included the experimental design where the treatments were developed. The study …

Apparent Digestibility In Vicunas Fed With Soft Straw And Alfalfa In The C.E.A.C., Felisa Capriles Apaza

Theses and Dissertations

South American camelids are a source of fiber and meat for the inhabitants of the Andean region of Bolivia, Argentina, and Chile. When camelids are well fed they efficiently convert the Andean flora into meat with high protein content. Vicuñas have a great capacity to produce wool to be used as a high quality fiber. However, the yield of vicuña meat production is generally low. There have been several studies concerning nutritional forage sources for camelids, resulting in improved nutrition, decreased morbidity and mortality, and intensified production systems. Soft straw is a source of tough forage with low protein content. …

Animal, Dairy, and Veterinary Science Faculty Publications

Excess consumption of selenium (Se) accumulator plants can result in selenium intoxication. The objective of the study reported here was to compare the acute toxicosis caused by organic selenium (selenomethionine) found in plants with that caused by the supplemental, inorganic form of selenium (sodium selenite). Lambs were orally administered a single dose of selenium as either sodium selenite or selenomethionine and were monitored for 7 days, after which they were euthanized and necropsied. Twelve randomly assigned treatment groups consisted of animals given 0, 1, 2, 3, or 4 mg of Se/kg of body weight as sodium selenite, or 0, 1, …

Standard And Routine Metabolic Rates Of Juvenile Sandbar Sharks (Carcharhinus Plumbeus), Including The Effects Of Body Mass And Acute Temperature Change, W. Wesley Dowd, Richard W. Brill, Peter G. Bushnell, John A. Musick

Biology Faculty Works

Standard and routine metabolic rates (SMRs and RMRs, respectively) of juvenile sandbar sharks (Carcharhinus plumbeus) were measured over a range of body sizes (n=34) and temperatures normally associated with western Atlantic coastal nursery areas. The mean SMR Q10 (increase in metabolic rate with temperature) was 2.9 ±0.2. Heart rate decreased with increasing body mass but increased with temperature at a Q10 of 1.8−2.2. Self-paired measures of SMR and RMR were obtained for 15 individuals. Routine metabolic rate averaged 1.8 ±0.1 times the SMR and was not correlated with body mass. Assuming the maximum metabolic rate of sandbar sharks is 1.8−2.75 …

Nematodes In Western Australian Vineyards, Vivien Vanstone, Neil Lantzke

Bulletins 4000 -

Nematodes are worm-like microscopic animals that live in the soil. There are numerous soil-inhabiting nematode species, but not all are harmful to plants. Some nematodes are plant-parasitic, feeding on and damaging roots, including those of grapevine. Feeding activities of these nematodes reduce the vine’s ability to take up water and nutrients from the soil, leading to lack of vigour, symptoms of nutrient deficiency, wilting, lower yield, vine decline and, in severe cases, vine death. Nematode feeding sites can also lead to entry of other disease-causing organisms (e.g. fungi or bacteria), resulting in rapid vine decline.

Nematodes can survive in the …

Long-Distance Dispersal And Population Trends Of Moose In The Central United States, Justin D. Hoffman, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

Dispersal is a basic feature of the natural history of moose. Most information about moose dispersal pertains to short-distance movements because long-distance movements are uncommon and difficult to observe. Since the 1950s, moose populations have been increasing in Minnesota and North Dakota. This may have contributed to several long-distance dispersal events for moose that recently were reported in the central United States. These dispersal events provide an opportunity to investigate both the causes and the biological implications of this rare phenomenon. Herein, we review long-distance dispersal events based on information obtained from a variety of sources. Dispersal routes that could …

Urine-Marking And Ground-Scratching By Free-Ranging Arctic Wolves, Canis Lupus Arctos, In Summer, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Urine-marking and ground-scratching were observed in an Arctic Wolf (Canis lupus) pack on Ellesmere Island, Nunavut, Canada, during 16 summers between 1986 and 2005. All previously known urination postures and ground-scratching by breeding males and females were seen, and incidence of marking and scratching was greatest when non-pack wolves were present. Observations of urine-marking of food remains supported the conclusion from a captive Wolf study that such marking signals lack of edible food.

Parelaphostrongylus Odocoilei In Columbia Black-Tailed Deer From Oregon, Jack A. Mortenson, Arthur Abrams, Benjamin M. Rosenthal, Detiger Dunams, Eric P. Hoberg, Robert J. Bildfell, Richard L. Green

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Documenting the occurrence of Parelaphostrongylus odocoilei has historically relied on the morphological examination of adult worms collected from the skeletal muscle of definitive hosts, including deer. Recent advances in the knowledge of protostrongylid genetic sequences now permit larvae to be identified. Dorsal-spined larvae (DSLs) collected in 2003–2004 from the lung and feces of six Columbian black-tailed deer (Odocoileus hemionus columbianus) from Oregon were characterized genetically. The sequences from unknown DSLs were compared to those from morphologically validated adults and larvae of P. odocoilei at both the second internal transcribed spacer (ITS-2) of ribosomal DNA and the mitochondrial cytochrome …

I studied the winter ecology of the Piping Plovers on Little St. Simons Island (LSSI), Georgia, from 2003-2006, with emphasis on the conservation significance of this site for the endangered Great Lakes population. During 2003-2004 and 2004-2005, LSSI supported up to 100 Piping Plovers during peak migration, and approximately 40 birds wintered at this site. All populations had …

Molecular Population Genetics Of The Atlantic Sand Fiddler Crab, Uca Pugilator, Along The Atlantic Coast, David A. Weese

College of Graduate Studies: Theses & Dissertations

Author's abstract: The Atlantic sand fiddler crab, Uca pugilator, is an extremely abundant fiddler crab found along the eastern and Gulf coast of the United States. Fiddler crabs have a life cycle with an obligatory planktonic larval phase of 30-90 days, which might be expected to lead to widespread larval dispersal and consequent genetic homogeneity over considerable distances. However a large amount of morphological and behavioral variation is found between northern and southern populations along the eastern coast. This study was undertaken to determine the population genetic structure of U. pugilator and to determine whether these differences may have a …

Changes In Demersal Wild Fish Aggregations Beneath A Sea-Cage Fish Farm After The Cessation Of Farming, Fernando Tuya, Pablo Sanchez-Jerez, Tim Dempster, Arturo Boyra, Ricardo Haroun

School of Natural Sciences Publications

Demersal, non-cryptic, wild fish were counted in replicate 100 m2 transects beneath a floating sea-cage fish farm and two nearby sandy locations at Gran Canaria (Canary Islands, eastern Atlantic) four times before and after the cessation of farming. Cessation of farming involved the removal of farmed fish and ceasing of the daily feeding, although farm structures (cages and moorings) remained. A “beyond-BACI” sampling design provided the framework to detect the effect of the cessation of farming, which produced qualitative and quantitative changes in the composition and structure of the fish assemblages beneath the sea-cage fish farm compared with two nearby …

Neoteny And The Plesiomorphic Condition Of The Plesiosaur Basicranium, F. Robin O’Keefe

Biological Sciences Faculty Research

The purpose of this paper is to describe the condition of the braincase in stratigraphically early and morphologically primitive plesiosaurs. Information on the braincase of plesiomorphic taxa is important because it establishes the polarity of characters occurring in more derived plesiosaurs. This paper begins with a short review of braincase anatomy in stem-group sauropterygians. Data on braincase morphology of the plesiomorphic plesiosaur genera Thalassiodracon and Eurycleidus are then presented and interpreted via comparison with other plesiosaurs, stemgroup sauropterygians, and stem diapsids (Araeoscelis). Early diapsids are relevant because plesiosaur skulls more closely resemble early diapsids than stem-group sauropterygians in several key …

Effects Of Dietary Fluoride Levels On Growth, Serum Indexes And Antioxidant Systems In Growing Pigs, Xin Tao, Zi Rong Xu, Yi Zhen Wang

Turkish Journal of Veterinary & Animal Sciences

Ninety-six growing pigs were used to evaluate the effects of fluoride levels on growth performance, serum indexes and antioxidant systems. Four dietary treatments were formulated by supplementing fluorine (as NaF) to provide the following added fluorine levels: 0, 50, 100 and 150 mg/kg. The results showed that pigs consuming diets with 100 and 150 mg/kg fluorine added had poor growth performance, and most serum biochemical indexes were significantly altered compared to the control (P < 0.05). On the other hand, serum and liver MDA concentration significantly increased due to the addition of 150 mg/kg fluorine (P < 0.05). T-AOC levels and the activities of SOD, GSH-PX, CAT and GST of serum and liver in fluoride added groups decreased, most of which altered significantly (P < 0.05). These results indicated that excessive fluoride ingestion had an adverse effect on animal health and performance.

The Effect Of Dietary Oils In Prevention Of Conjugated Linoleic Acid-Induced Embryo Mortality In Fertile Eggs From Artificially Inseminated Chickens, Rahi̇m Aydin

Turkish Journal of Veterinary & Animal Sciences

Dietary conjugated linoleic acid (CLA) decreases the ratio of unsaturated fatty acids/saturated fatty acids (UFA/SFA) in yolk and induces embryo mortality in fertile chicken eggs.
