Turkish Journal of Veterinary & Animal Sciences

This experiment was conducted to study the effects of different enzyme supplementation to wheat-and barley-based diets on the live weight gain, feed efficiency, dressing percentage and ileal pH of broiler chickens. Two hundred fourtyfive, day-old Ross-PM3 chicks were randomly assigned to a control and four treatment groups. Starter (1 to 21 days old) and grower (22 to 42 days old) diets were given without (control) or with different enzyme preparations, which are Avizyme 1200 (1000 mg/kg), Kemzyme Dry (500 mg/kg), Roxazyme-G (200 mg/kg) and Wheatzyme (700 mg/kg). At the end of the six week, average live weights of broilers were …

Turkish Journal of Zoology

Experimental cages started with a mixture of flies at three different ratios (1:9, 5:5, 9:1) from populations having heterosomal and autosomal sex-determining mechanisms were cytogenetically examined over six generations at two different temperatures (25 °C and 35 °C). In general, there was an increase in the frequency of XX males in all competitive population cages. Abnormal testes and intersex appearance, frequent X chromosome aneuploidies and deviation from a 1:1 sex ratio were observed.

Characterization Of The Jembrana Disease Virus Tat Gene And The Cis- And Trans-Regulatory Elements In Its Long Terminal Repeats, Hexin Chen, Graham Wilcox, Gde Kertayadnya, Charles Wood

Nebraska Center for Virology: Faculty Publications

Jembrana disease virus (JDV) is a newly identified bovine lentivirus that is closely related to the bovine immunodeficiency virus (BIV). JDV contains a tat gene, encoded by two exons, which has potent transactivation activity. Cotransfection of the JDV tat expression plasmid with the JDV promoter chloramphenicol acetyltransferase (CAT) construct pJDV-U3R resulted in a substantial increase in the level of CAT mRNA transcribed from the JDV long terminal repeat (LTR) and a dramatic increase in the CAT protein level. Deletion analysis of the LTR sequences showed that sequences spanning nucleotides 268 to 153, including the TATA box and the predicted first …

Affinity Chromatography: A Review Of Clinical Applications, David S. Hage Jan 1999

Affinity Chromatography: A Review Of Clinical Applications, David S. Hage

David Hage Publications

Affinity chromatography is a type of liquid chromatography that makes use of biological-like interactions for the separation and specific analysis of sample components. This review describes the basic principles of affinity chromatography and examines its use in the testing of clinical samples, with an emphasis on HPLCbased methods. Some traditional applications of this approach include the use of boronate, lectin, protein A or protein G, and immunoaffinity supports for the direct quantification of solutes. Newer techniques that use antibody-based columns for on- or off-line sample extraction are examined in detail, as are methods that use affinity chromatography in combination with …

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard Jan 1999

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard

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

Few studies of monogamous canids have addressed regurgitation in the context of extended parental care and alloparental care within family groups. We studied food transfer by regurgitation in a pack of wolves on Ellesmere Island, North West Territories, Canada, during 6 summers from 1988 through 1996. All adult wolves, including yearlings and a post-reproductive female, regurgitated food. Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5. Pups were more likely to receive regurgitations (81%) than the breeding female (14%) or auxiliaries (6%). The breeding male regurgitated mostly to the breeding female …

Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech Jan 1999

Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech

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

We examined the seasonal migration and home-range dynamics of a multigeneration white-tailed deer (Odocoileus virginianus) matriline comprising six females from four generations spanning a 20-year period in northeastern Minnesota. All, from the matriarch to her great-granddaughter, migrated to the same summer and winter ranges, the longest individual record being 14.5 years. Three maternal females concurrently occupied exclusive fawning sites within their ancestral matriarch’s summer range, while two nonmaternal females explored new areas and ranged near their mothers. One great-granddaughter expanded her summer range 1 km beyond the matriarch’s summer range while essentially vacating half of her ancestors’ range …

School of Veterinary and Biomedical Sciences: Faculty Publications

Gnotobiotic piglets were inoculated intralaryngeally with swine Chlamydia trachomatis strain R33 or orally with swine C. trachmatis strain R27. Archived formalin-fixed, paraffin-embedded tissues from piglets euthanatized 4–7 days postinoculation were examined by in situ hybridization for C. trachomatis nucleic acid using a nonradioactive digoxigenin-labeled DNA probes that targeted specific ribosomal RNA or omp1 mRNA molecules of the swine C. trachomatis strains. Positive hybridization signals were detected in bronchial epithelial cells, bronchiolar epithelial cells, pneumocytes, alveolar and interstitial macrophages, and jejunal and ileal enterocytes. Chlamydia-infected cells had a strong signal that was confined to the intracytoplasmic inclusions. Positive hybridization signals were …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Discovery of the ostertagiine nematode Teladorsagia boreoarcticus n. sp. in muskoxen, Ovibos moschatus, from the central Canadian Arctic highlights the paucity of knowledge about the genealogical and numerical diversity of nematode faunas characteristic of artiodactyls at high latitudes across the Holarctic. Teladorsagia boreoarcticus is a dimorphic cryptic species distinguished from Teladorsagia circumcincta/Teladorsagia trifurcata in domestic sheep by a 13% divergence in the ND4 region of mitochondrial DNA, constant differences in the synlophe, and significantly longer esophageal valve, spicules, gubernaculum, and bursa. Teladorsagia boreoarcticus represents an archaic component of the North American fauna and may have a Holarctic …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Lymph nodes from 271 white-tailed deer (Odocoileus virginianus) and mule deer (Odocoileus hemionus) in Nebraska (USA) were examined microscopically for tuberculoid lesions. Lymph nodes lesions in at least one node were found in 12 deer. Lesions were examined with Zeihl-Neelson acid fast stains and by polymerase chain reactions using M. bovis specific probes. No evidence of tuberculosis was found. The small granulomatous lesions were likely caused by other bacteria.
