Determination Of Plasma Fibrinogen And Haptoglobin, Hematological And Blood Biochemical Changes In Bulgarian Local Goats With Experimentally Induced Staphylococcus Aureus Mastitis, Ivan Fasulkov, Manol Karadaev, Nasko Vasilev, Valentina Urumova, Teodora Mircheva

Turkish Journal of Veterinary & Animal Sciences

The aim of the present study was to assess changes in acute phase proteins fibrinogen and haptoglobin, as well as hematological, blood biochemical, and microbiological alterations in local Bulgarian goats with experimentally induced Staphylococcus aureus mastitis. The experiments were conducted with 6 clinically healthy local Bulgarian goats, 2 to 6 years of age, weighing 46-57 kg. The experimental infection was done with a stationary phase culture of a field Staphylococcus aureus strain isolated from a cow with clinical mastitis. Blood haptoglobin in goats was considerably higher (P < 0.05) as early as 8 h after the pathogen's inoculation. The most significant differences from baseline values occurred 24 and 48 h (P < 0.01) after infection. Plasma fibrinogen increased significantly (P < 0.05) 8 h after infection and reached the highest mean concentration (9.12 g/L) by 72 h. Leukocytosis was established as early as 4 h after the experimental infection when leukocyte counts were significantly higher than baseline (P < 0.001). The analysis of results indicates that in experimentally induced Staphylococcus aureus mastitis, significantly higher (P < 0.05) levels of the leukocyte, fibrinogen, and haptoglobin are established as early as 8 h after the infection.

Estimation Of Genetic And Phenotypic Parameters For Daily Milk Yield Of Black Bengal Does, Md. Mohan Mia, Mobarak Akter Md. Yahia Khandoker, Syed Sakhawat Husain, Md. Omar Faruque, David Russell Notter

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the genetic and phenotypic parameters for daily milk yield (DMY) in Black Bengal does. Genetic parameters were estimated using a residual maximum likelihood procedure, fitting an animal model while ignoring maternal genetic or permanent environmental effects. The least squares mean for DMY was 354.76 g. DMY was significantly (P < 0.01) affected by parity, litter size, and season of kidding. The heritability of DMY was low (0.15) and the fact that the trait can only be measured in females suggests that progeny testing may be the best sire selection method for this trait.

Turkish Journal of Veterinary & Animal Sciences

In the present study, sensitive and mutant colonies of some ruminal bacterial species isolated from sheep, cattle, and buffalo were detected. We counted and considered \"mutant colonies\" the bacterial colonies grown in the clear inhibition zone in the Kirby-Bauer disk diffusion susceptibility test. Detected mutant colonies were higher in buffalo than in cattle and sheep. Duricef and metronidazole caused no mutations in any species. The others formed mutant colonies, where roxithromycin = polymyxin = chloramphenicol = gentamicin < erythromycin < vancomycin < piperacillin = cefotaxime < streptomycin < cefoperazone < ciprofloxacin < amikacin. Sheep had the highest number of sensitive isolates, and the number of sensitive isolates was dramatically lower in cattle and buffalo. There were no sensitive isolates with the antibiotic metronidazole, and there was a low number of sensitive isolates with duricef. The other antibiotics had more sensitive isolates (gentamicin = ciprofloxacin = amikacin > streptomycin = piperacillin > erythromycin > vancomycin = cefoperazone = cefotaxime > roxithromycin > polymyxin > chloramphenicol). The number of sensitive isolates of the different ruminant species for …

Australian Journal of Teacher Education

Literacy is promoted as one factor in overcoming disadvantage. In this paper, we employ Fraser’s (1997 & 2008) framing of social justice in order to analyse the disparate agendas of literacy education for improved outcomes in national policy. We do this to better understand the dilemmas confronting preservice teachers as they prepare to become teachers in complex education contexts. We then examine what 20 preservice primary teachers say about social justice in interview responses to a scripted scenario. Our findings demonstrate that most preservice teachers are trying to demonstrate that they have a well-placed commitment to teaching for social justice, …

Teaching Reading: Why The “Fab Five” Should Be The “Big Six”, Deslea Konza Jan 2014

Teaching Reading: Why The “Fab Five” Should Be The “Big Six”, Deslea Konza

Australian Journal of Teacher Education

The Report of the National Reading Panel (NICHD, 2000) identified five key elements that were critical to the development of reading, and these have been widely accepted by educational jurisdictions as providing definitive guidelines for early reading instruction. This paper presents a case for the inclusion of oral language and early literacy experiences as an additional and foundational element. The pervasive influence of a child’s early experiences on future reading achievement must be understood if teachers are to maximise the opportunities of all children to become independent readers.

New Understanding Of An Old Phenomenon: Uncontrolled Factors And Misconceptions That Cast A Shadow Over Studies Of The ‘Male Effect’ On Reproduction In Small Ruminants, Trina Jorre De St Jorre, Penny Alison Rhian Hawken, Graeme Bruce Martin

Turkish Journal of Veterinary & Animal Sciences

In female sheep and goats, exposure to males can be used to induce ovulation and thus control and synchronise fertility. This 'male effect' offers simple, cost-effective, and hormone-free management of reproduction in flocks and herds but, despite decades of research, significant gaps in our knowledge impede commercial application. Many of these gaps can be traced back to misconceptions in the early documentation of the male effect, and others are the result of uncontrolled factors in experimental design. Consequently, it is often difficult to draw conclusions from past research, to further our understanding of the phenomenon, and to make recommendations for …

Usefulness Of Short Sequence Repeat Markers In Goat Genetic Diversity Studies On The Asian And African Continents, Faiz M.M.T. Marikar, Muneeb M. Mustafa Jan 2014

Usefulness Of Short Sequence Repeat Markers In Goat Genetic Diversity Studies On The Asian And African Continents, Faiz M.M.T. Marikar, Muneeb M. Mustafa

Turkish Journal of Veterinary & Animal Sciences

Goat genetic diversity studies are very important since extinction of germ plasma is increasing very rapidly. The African and Asian continents are the hotspots for indigenous animals with fewer genetic manipulations. Conservation studies using molecular markers have the capability to validate the real status of the animals. The use of molecular markers has revolutionized studies of genetic diversity. Even though a number of markers are used for these types of studies, short sequence repeats are in the forefront due to their superior features such as high variability, high mutation rate, large number, distribution throughout the genome, codominant inheritance, and neutrality …

Polledness Intersex Syndrome In Goats – Molecular And Histological Aspects, Iwona Szatkowska, Daniel Zaborski, Witold Stanislaw Proskura, Sara Tabor

Turkish Journal of Veterinary & Animal Sciences

Polledness intersex syndrome (PIS) is a phenomenon associated with 2 distinct conditions occurring in goats, namely polledness and intersexuality. The first is a trait exhibiting complete dominance, whereas the latter is recessive. The extreme case of intersexualism is complete sex reversal, which is observed only in females (60,XX). The trait PIS is inherited in a recessive manner and caused by deletion of 11.7 kbp DNA on chromosome 1q43. Female goats with PIS exhibit a broad range of developmental abnormalities of the sexual system, from only subtle changes to complete sex reversal. The phenotypic diversity in goats with PIS is most …

Turkish Journal of Veterinary & Animal Sciences

Spermatogonial stem cells (SSCs) are the best candidates for exploitation in genetic improvement of cattle herds. In fact, SSCs transmit genetic information to future generations. In vitro improvement in proliferation and frozen-thawed SSCs numbers is therefore needed. In the present study, bovine SSCs were cocultured with Sertoli cells, with or without insulin-like growth factor 1 (IGF-1). During 16 days of incubation, 100 ng/mL IGF-1 showed higher efficacy in increasing the numbers and diameters of SSCs colonies than 40 and 150 ng/mL concentrations. Furthermore, 100 ng/mL IGF-1 increased the frozen/thawed cells’ viability rate. Overall, these data demonstrate that usage of 100 …

The Avian Ovary And Follicle Development: Some Comparative And Practical Insights, Alan L. Johnson Jan 2014

The Avian Ovary And Follicle Development: Some Comparative And Practical Insights, Alan L. Johnson

Turkish Journal of Veterinary & Animal Sciences

This review focuses on recent research related to the avian ovary and, in particular, cellular mechanisms mediating embryonic growth of the ovary, postembryonic follicular development, and the process of follicular selection. Attention is drawn to a variety of fundamental, yet unresolved, aspects of ovarian function, several of which are uniquely related to avian reproductive strategies. Some notable differences in ovarian function between birds and the most closely related extant group, the crocodilians, are illustrated. Moreover, because the sauropsid (reptilian and avian) and synapsid (mammalian) lineages diverged shortly after the emergence of amniotes some 340 million years ago, consideration is given …
