The Fecb (Booroola) Gene And Implications For The Turkish Sheep Industry, Asi̇ye Yilmaz Adkinson, Robert Wayne Adkinson Jan 2013

The Fecb (Booroola) Gene And Implications For The Turkish Sheep Industry, Asi̇ye Yilmaz Adkinson, Robert Wayne Adkinson

Turkish Journal of Veterinary & Animal Sciences

Most traits of economic importance in livestock are quantitative traits. This means that they are influenced by a large number of genes, each contributing a small effect, scattered across the genome. Selection for these genes requires specialized methods such as progeny testing or genomic selection. The FecB or Booroola gene is an exception. Presence of this single gene increases ovulation and lambing rates dramatically with ewes producing 2, 3, or even more lambs per parturition. The FecB gene was first observed indirectly in Australian Merino sheep by Dr Helen Newton Turner. It was later determined that this allele was a …

Comparison Of Growth And Reproduction Of Mirror Carp And Scaled Carp Introduced Into Gelingüllü Reservoir, Yozgat, Turkey, Şeri̇fe Gülsün Kirankaya, Fitnat Güler Ekmekçi̇

Turkish Journal of Veterinary & Animal Sciences

Carp have been translocated and introduced outside of their natural range in many countries. In Turkey, mirror carp (a warm-water fish) has generally been introduced into man-made reservoirs for fishery management, regardless of geographic location and climatic conditions. During the previous decade, controversy has arisen concerning the adaptation and spawning of carp, and the success of such introduction practices in Central Anatolia, which is characterized by typical cold continental weather conditions. Concurrently, based on some irregular observations, scaled carp was reintroduced as an alternative to mirror carp. Long-term monitoring studies on the growth and reproduction of mirror carp and scaled …

Impact Of The Haberlea Rhodopensis Extract On The Innate Immune System And Response In Rabbits Following Klh-Hemocyanin Immunization And Cyclophosphamide Treatment, Svetlana Georgieva, Lilian Sotirov, Borislav Popov, Tsvetoslav Koynarski

Turkish Journal of Veterinary & Animal Sciences

The aim of the present investigation was to study the impact of Haberlea rhodopensis extract on the innate immune response in rabbits. The complement and lysozyme activity, percent phagocytosis, and phagocytic index were studied. The analysis of the results showed that the treatment with Haberlea rhodopensis extract, cyclophosphamide, and KLH renders a remittent effect upon the classical pathway of activation of the complement system and the lysozyme concentration in the rabbit blood serum. These same factors have no direct effect on the phagocytic activity in the investigated animals. The obtained data show limited effect of Haberlea rhodopensis extract on rabbits’ …

Effect Of Natural Zeolite (Clinoptilolite) On The Performance And Litter Quality Of Broiler Chickens, Ioannis Nikolakakis, Vassilis Dotas, Anastasios Kargopoulos, Lampros Hatzizisis, Dimitris Dotas, Zafiris Ampas

Turkish Journal of Veterinary & Animal Sciences

This work was conducted to study the effect of dietary supplementation with natural zeolite on the performance and litter quality of broilers. In a randomized complete block experimental design, 480-day-old Cobb-500 broilers were divided into 4 treatments with 4 replicates each and 30 chicks per replicate. The dietary treatments consisted of a control wheat-corn-soybean meal diet (C) and 3 others contained 1.0%, 2.0%, or 3.0% zeolite for Z_1, Z_2, and Z_3 treatments, respectively. Feed intake was significantly (P < 0.05) higher in Z_1, Z_2, and Z_3 treatments as compared to the control diet. Compared to the control, diets containing 2% and 3% of zeolite showed a significant (P < 0.05) increase in body weight gain and feed conversion ratio for the total period. The dietary addition of zeolite significantly (P < 0.05) decreased the organic content in litter samples throughout the experimental period. The results of this study showed that the dietary addition of natural zeolite at inclusion rates of 2% and 3% had a positive effect on feed conversion ratio, body weight gain, and litter quality of broilers.

Clostridium Botulinum In Honey: Prevalence And Antibiotic Susceptibility Of Isolated Strains, Ahmet Koluman, Berfi̇n Meli̇koğlu Gölcü, Okan Deri̇n, Si̇bel Özkök, Fabrizio Anniballi

Turkish Journal of Veterinary & Animal Sciences

Clostridium botulinum and rare strains of C. butyricum and C. baratii produce an extremely potent toxin, the botulinum neurotoxin (BoNT). Infant botulism is significant for both its high mortality rates and for the sophisticated treatment that it requires. Isolation and identification of C. botulinum according to standards depend on mouse bioassays to determine toxin-producing ability of strains. Polymerase chain reaction (PCR) is used to detect the types of toxins expressed by bacteria. Since honey is an important source of infant botulism, we determined the types of toxins secreted by C. botulinum strains and their antibiotic resistance. In this study, the …

The Effects Of Barley/Triticale Silage On Performance, Carcass Characteristics, And Meat Quality Of Lambs, Gülcan Demi̇rel, Ahmet Yavuz Pekel, Bülent Eki̇z, Hakan Bi̇ri̇ci̇k, Neşe Kocabağli, Müjdat Alp

Turkish Journal of Veterinary & Animal Sciences

This study was conducted to investigate the performance, carcass characteristics, and meat quality of lambs fed barley/triticale silage treated with/without inoculant and enzyme mixture-based diets with similar barley supplementation. Thirty Tahirova × Sakız crossbred weaned ram lambs (mean body weight: 34 ± 0.5 kg) were used in this study. Lambs were randomly divided into groups of 3 and fed the respective diets. These 3 diets were: 1) hay grass + barley, 2) triticale/barley silage + barley, and 3) triticale/barley silage with inoculants and enzyme mixture + barley. There were significant differences among groups in daily live weight gain (P < 0.001). Cold carcass weight and dressing percentage based on empty body weight and carcass conformation scores were not significantly different among groups, but fatness scores and proportion of omental and mesenteric fat were significantly affected by diet (P < 0.05). No differences were found in terms of meat lightness (L*), redness (a*), and yellowness (b*) values for M. longissimus thoracis muscle. However, silage-fed lambs in both groups had higher shear force values than hay-fed lambs in the current study (P < 0.05). It can be concluded that barley/triticale silages offered with concentrate had no unfavorable effect on lamb performance, carcass characteristics, and meat quality.


Carbon Dioxide Laser-Assisted Staphylectomy In Brachycephalic And Nonbrachycephalic Dogs, Adolfo Maria Tambella, Cecilia Vullo, Fabrizio Dini, Angela Palumbo Piccionello, Anna Rita Attili Jan 2013

Carbon Dioxide Laser-Assisted Staphylectomy In Brachycephalic And Nonbrachycephalic Dogs, Adolfo Maria Tambella, Cecilia Vullo, Fabrizio Dini, Angela Palumbo Piccionello, Anna Rita Attili

Turkish Journal of Veterinary & Animal Sciences

Elongated soft palate is a common upper airway anomaly in brachycephalic dogs. The scientific literature considering this pathology in nonbrachycephalic dogs is limited. The aim of this study was to estimate the importance of the elongated soft palate in nonbrachycephalic dogs (n = 10), carrying out, at the same time, a comparison with selected brachycephalic dogs (n = 19), on the effect of carbon dioxide laser staphylectomy. The selected population had only elongated soft palates and no other disorders. The surgery was rapid and uncomplicated; no suture material was used. The comprehensive recovery was significant (P < 0.0001): 68.4% of brachycephalic dogs and 100% of nonbrachycephalic dogs had complete recovery. The incomplete recovery in older brachycephalic dogs matched a more advanced pathologic phase. This study suggests that, in the case of high respiratory tract alteration and poor exercise tolerance, it is imperative to consider in differential diagnosis the elongated soft palate in nonbrachycephalic breeds, too; their clinical signs are less severe and frequently underestimated. The surgical treatment has a favorable prognosis when the only alteration is elongated soft palate. The carbon dioxide laser has been confirmed as an useful option for staphylectomy in dogs.

First Report Of Cryptosporidium Spp. And Giardia Duodenalis In Calves From Northeastern Brazil, Thais Ferreira Feitosa, Vinícius Longo Ribeiro Vilela, Ana Célia Rodrigues Athayde

Turkish Journal of Veterinary & Animal Sciences

This study aimed to investigate the occurrence of Cryptosporidium spp. and Giardia spp. in cattle calves from the Sertão region of Paraíba State in northeastern Brazil. The experiment was conducted using 100 calves from 10 farms. To evaluate the presence of oocysts, the technique of flotation in a sucrose solution was used, and for detection of C. parvum and G. duodenalis, the immunochromatographic test RIDA®QUICK Cryptosporidium/Giardia strips were used. It was noted that animals of 1 to 30 days of age were statistically more affected (P < 0.05) by Cryptosporidium spp. Only 4 calves (25% of the positive animals) had diarrhea (P < 0.05). Nine animals were positive for G. duodenalis; diarrhea was present in 6 (66.67%) of those animals, which was considered a risk factor (P < 0.05). It was concluded that Cryptosporidium spp. and G. duodenalis were present in calves from northeastern Brazil.

Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna Jan 2013

Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna

All Master's Theses

Beaver reintroduction programs are increasingly being viewed as a way to enhance salmonid habitat and production. However, the actual effectiveness of using beavers as a habitat enhancement tool for ESA listed steelhead Oncorhynchus mykiss populations is unknown. We examined the type of habitat, at both the microhabitat and mesohabitat levels, preferred by steelhead in three small streams in the upper Yakima Basin, WA through standard snorkel surveys and habitat measurements. Our results suggest that steelhead in small streams strongly prefer (relative to availability) microhabitats that have deeper water(> 30 cm), slow stream velocities(< 0 .05 mis), and complex cover types. Habitat partitioning among the size-classes (small< 50 mm, medium 50-90 mm, large> 90 mm total length, TL) principally operated …

Evaluating And Role Of Standards And Guidelines In National Forest Planning, Emily E. Schembra Jan 2013

Evaluating And Role Of Standards And Guidelines In National Forest Planning, Emily E. Schembra

Graduate Student Theses, Dissertations, & Professional Papers

There is longstanding conflict related to planning standards and guidelines (S & Gs) used by the U.S. Forest Service to guide and constrain National Forest System land management. The role these prescriptions have played in the past in forest management, and the role they ought to play in the future, is often disputed. However, the National Forest Management Act (NFMA) and the new 2012 NFMA planning regulations require S & Gs, so they must be included in forest plans in the future. The goal of this research was to provide a common understanding of how planning S & Gs were …


Biological Effects Of Trogocytosis On Cd4+ T Lymphocytes, Douglas Grant Osborne Jan 2013

Biological Effects Of Trogocytosis On Cd4+ T Lymphocytes, Douglas Grant Osborne

Graduate Student Theses, Dissertations, & Professional Papers

Antigen recognition by CD4+ T cells leads to large-scale spatial and temporal molecular redistributions, forming the immunological synapse. We have previously shown that upon dissociation, T cells capture large membrane fragments from antigen-presenting cells directly from the immunological synapse. The mechanism and biological significance of this process, termed trogocytosis, is still unclear. In this thesis I examined the impact that trogocytosis has on the individual T cell after capturing molecules from the antigen presenting cell. I employed murine fibroblast cell lines expressing an I-Ek molecule loaded with a covalently attached antigenic peptide (moth cytochrome C 88-103) and with or without …

A Molecular Genetic Investigation Of The Regulation Of Outer Surface Protein C In Borrelia Burgdorferi: Identification And Characterization Of The Novel Regulatory Protein Bbd18, Beth Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Lyme disease, caused by Borrelia burgdorferi, is the most prevalent arthropod-borne disease in the U.S. In nature, B. burgdorferi is maintained in an enzootic cycle between Ixodes ticks and mammalian hosts. In order to cause infection in mammals, B. burgdorferi spirochetes within a feeding tick sense environmental changes and subsequently alter their gene expression and protein profiles. As part of this adaptation, spirochetes within the tick midgut downregulate outer surface protein (Osp) A and upregulate OspC. Although OspC is an essential B. burgdorferi virulence factor needed for early mammalian infection, it is also a target for the mammalian acquired immune …
