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

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’ …

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 …

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
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
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 …

Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
Effects Of Different Weaning Management Strategies On Preconditioning Performance, Haptoglobin Serum Levels, Feedlot Morbidity, And Carcass Characteristics, Jake Everitt Anderson
LSU Master's Theses
Weaning, one of the first major stressors encountered by the calf, has a negative effect on the immune system and increases the likelihood of infection of novel pathogens such as those that cause bovine respiratory disease. Fenceline contact at weaning has been shown to reduce the stress on the calf during the time following maternal separation. Preconditioning programs have been shown to reduce feedlot morbidity and mortality. Combining these two management practices could reduce the length of time calves need to be held in a preconditioning program. A multi-year study was conducted to evaluate if fenceline weaning will allow for …
Yogurt Cultured Milk Powder As A Substitute For Yogurt Powder, Lijie Song
Yogurt Cultured Milk Powder As A Substitute For Yogurt Powder, Lijie Song
LSU Master's Theses
Commercial yogurt powder has to go through drying process which kills the yogurt culture, so the health benefit of the yogurt culture bacteria are lost. Also, upon reconstitution commercial yogurt powder does not taste like yogurt, it is sour and off flavored. The hypothesis of this study was that yogurt cultured milk powder would have better culture bacterial counts, better physico-chemical and sensory characteristics than commercial yogurt powder currently available. Commercial yogurt powder (CYP) was the control and yogurt cultured milk powder (YCMP) was the treatment. Freeze-dried yogurt starter culture (Lactobacillus bulgaricus and Streptococcus thermophilus at ratio 1:1) was added …

Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
LSU Master's Theses
Consumers are becoming conscious of their diet, increasing protein intake and avoiding carbohydrates and fats. Whey proteins have branch chain amino acids responsible for muscle building. Whey protein isolate (WPI) contains more than 90% protein. The effect of incremental addition of WPI on probiotic characteristics of pure cultures and cultures in yogurt and yogurt characteristics are not known. The hypothesis was that “added” WPI will influence the characteristics of yogurt culture bacteria in pure form and in yogurt. The objectives were: to determine the influence of added WPI on (1) acid and bile tolerance, growth and protease activity of pure …

Vitrification Of Equine Expanded Blastocysts, Fabian Andres Diaz
Vitrification Of Equine Expanded Blastocysts, Fabian Andres Diaz
LSU Master's Theses
The cryopreservation of equine expanded blastocysts (>300 um) has been largely unsuccessful primarily due to the low permeability to cryoprotectants and the large size of the equine embryo. Mechanical alternatives may provide means to overcome the capsule barrier and the relative large embryo size. In this regard, multiple experiments were performed in this study to evaluate different approaches of capsule puncture and blastocoele fluid extraction with the objective to develop a cryopreservation protocol for Day 8 equine expanded blastocysts. In the first experiment, twenty-four Day 8 expanded blastocysts were exposed to standard equine embryo vitrification solutions following one- or …

Bovine mastitis is most significant disease seen in dairy farms worldwide, resulting in the largest profit loss of any other disease affecting dairy cows. The aim of this thesis was to determine the predominant species responsible for bovine mastitis in a subset of ten Kentucky dairy herds, and to assess the presence of antibiotic resistance in these pathogens. In this study, 308 milk samples were obtained from cow's selected based on their recent somatic cell count. Samples positive for growth were identified using the gram stain and various biochemical tests. After identification, resistance to 11 antimicrobial agents was assessed using …
Breeding Biology Of Chuck-Will's-Widows: Incubation, Brooding, And Provisioning Behavior And Characteristics Of Nest Sites, Ryan Sean O'Connor
Breeding Biology Of Chuck-Will's-Widows: Incubation, Brooding, And Provisioning Behavior And Characteristics Of Nest Sites, Ryan Sean O'Connor

Chuck-will's-widows (Antrostomus carolinensis) are cryptically colored grounding-nesting nightars that breed throughout much of the eastern United States, primarily in mixed-forest habitat. Because of their cryptic plumage and nocturnal habits, little is known about their behavior, particularly their breeding and nesting behavior. Thus, my objectives were to: (1) quantify patterns of incubation behavior (e.g., on bouts vs. off bouts) and the respective roles of males and females, (2) quantify the brooding and provisioning behavior of males and females, and, (3) compare the characteristics of nest sites and randomly selected unused sites to determine those features important in nest site selection.

White-throated sparrows (Zonotrichia albicollis) are songbirds that spend the non-breeding season in southeastern North America, where they form philopatric territorial flocks. Flocks exhibit dominance hierarchies, with dominance rank associated with an individual's age and prior residence in the territory. Although social behaviors within flocks are well studied, few studies have described winter home ranges. I tagged white-throated sparrows (n = 12) in Madison County, Kentucky, with 0.9-g radio transmitters during the winter of 2010-2011. Locations were entered into ArcGIS and home range sizes were estimated with 50% and 95% kernel analysis for individuals with at least five locations. Mean core …
