The hypothalamic gonadotropin-releasing hormone receptor (GnRHR) plays an essential physiological role in reproductive function. In this investigation, we studied genetic variation in the entire coding region of GnRHR gene using PCR-SSCP technique in 250 Bos taurus (Holstein Friesian, Jersey) and Bos indicus (Malnad Gidda, Deoni) bulls. The genetic variants in GnRHR gene were determined by PCR-SSCP technique by using 5 sets of primers. SSCP analysis of fragment 1, comprising exon 1, and fragment 3, comprising exon 2, revealed 2 SSCP patterns in all breeds under study, while fragment 2 of exon 1 and fragment 4, comprising exon 3, revealed 3 …

Implementing Innovative Farm Management Practices On Dairy Farms: A Review Of Feeding Systems, Şeyda Özkan, Julian Hill
Turkish Journal of Veterinary & Animal Sciences
The Australian dairy industry relies primarily on pasture for its feed supply. However, the variability in rainfall negatively affects plant growth, leading to uncertainty in dryland feed supply, especially during periods of high milk price. New feeding (complementary) systems combining perennial ryegrass with another crop and/or pasture species may have the potential to mitigate this seasonal risk and improve productivity and profitability by providing off-season feed. To date, the majority of research studying the integration of alternative crops into pasture-based systems has focused on substitution and utilization of alternative feed sources. There has been little emphasis on the impacts of …

Turkish Journal of Veterinary & Animal Sciences
The obstetric assistance of dystocia in field conditions promotes greater bacterial contamination of the uterus, causing subclinical endometritis. The aim of this study was to determine the occurrence of subclinical endometritis in beef heifers receiving professional calving assistance, and to evaluate endometrial cytology as a diagnostic technique compared to uterine biopsy. A group of 829 Angus heifers were assisted at calving. Dystocia was classified based on difficulty at assistance, which was estimated as complex or simple. At the end of the calving season, 93 dystocic heifers were reported (10.7%). The percentage of simple resolution and complex resolution was 88.2% and …
Effects Of Alpha Lipoic Acid And Vitamin C Supplementation On Transforming Growth Factor Alpha (Tgf \Alpha) And Transforming Growth Factor Beta 2 (Tgf \Beta2)Secretion In Testicular Tissue Of Diabetic Rats, Sevda Eli̇ş Yildiz, Buket Bakir, Hami̇t Uslu, Ebru Karadağ Sari, Musa Karaman
Turkish Journal of Veterinary & Animal Sciences
The effects of alpha lipoic acid and vitamin C supplementation on TGF \alpha and TGF \beta2 secretion in the testicular tissue of streptozotocin-induced diabetic rats were examined by immunohistochemical methods. Rats were divided into 5 groups; group 1 (control), 2 (diabetic control), 3 (diabetes + alpha lipoic acid), 4 (diabetes + vitamin C), and 5 (diabetes + alpha lipoic acid + vitamin C). Hematoxylin and eosin staining was performed in order to examine testicular tissue histopathologically. The streptavidin-biotin-peroxidase complex method was used for histological examination and determination of TGF \alpha and TGF \beta2 localization in the testicular tissue. Regarding fasting …

Incidence And Occurrence Time Of Clinical Mastitis In Holstein Cows, Ismail Boujenane, Jalila El Aimani, Khalid By
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to assess the incidence of clinical mastitis (CM) and its risk factors in 1725 Holstein cows. Data were collected from a private farm from 2008 to 2012. The analysis of risk factors, performed with logistic regression, showed that cows at parity 2, 3, and 4 had 65%, 88%, and 115% risk of mastitis, respectively. This risk was higher (P < 0.001) than in cows at first parity. Cows that calved from October to January had the highest (P < 0.05) risk of mastitis. The number of mastitis cases in cows at lactation 2, 3, and 4 was 18.5%, 25.9%, and 40.7%, respectively, and was higher compared to cows at first lactation. Furthermore, cows that calved from July to September showed the highest number of mastitis cases. Gamma regression parameter estimates showed that the onset time of mastitis 1 and 2 in cows that calved from October to January occurred at 16.3 and 8.5 days, respectively. This was later than cows calving from July to September. The study concluded that it is necessary to examine cows for CM during the first 2 months of lactation in order to prevent mastitis and decrease its rate of incidence.

The aim of the present study was to determine the histological structure and histochemical properties of the pancreatic ducts in the goose Anser anser. Pancreatic ducts of 6 male and 6 female geese were examined. Crossman’s triple stain and Masson’s trichrome stain were used for histological examination, and periodic acid–Schiff, alcian blue, periodic acid–Schiff/alcian blue, and aldehyde fuchsin/alcian blue stainings were performed for histochemical examination. Dorsal and ventral pancreatic ducts were found that transfer pancreatic secretion into the duodenum of the goose, and these channels were found to have a histologically similar structure. No differences were detected between male and …

Turkish Journal of Veterinary & Animal Sciences
Two experiments were conducted to investigate the effect of supplemental zinc (Zn) on performance, nutrient digestibility, and plasma Zn status in Zandi lambs. In experiment 1, 18 male lambs (BW = 21.30 ± 0.55 kg) were fed a basal diet containing 22.8 mg Zn/kg dry matter (DM) with no supplemental Zn (control) or 20 mg of supplemental Zn/kg of DM from Zn sulfate (ZnS) or Zn peptide (ZnP). Average daily gain and dry matter intake were higher for the lambs fed the diet supplemented with ZnP. Feed conversion ratio was significantly (P < 0.05) lower in the ZnP group compared to the control and ZnS groups. In experiment 2, an in vitro gas production technique was used to evaluate the effects of zinc source on the gas production parameters. Rate of gas production after 6 h and total production of gas after 24 and 48 h did not differ between groups. In vitro DM digestibility, short-chain fatty acids, and ME content were increased (P < 0.05) by ZnP supplementation when compared to the ZnS and control groups. The results of this study showed that feeding ZnP improves performance and digestibility of DM and could result in higher metabolizable energy and short-chain fatty acid yield.

The purpose of this study was to determine the relationship between sarcomere length and basic composition (water, protein, ash, collagen, and fat content including marbling) of beef muscles with fast-twitch glycolytic (longissimus dorsi muscle) and slow-twitch oxidative fibers (infraspinatus muscle) in Limousin bulls. Samples (n = 15) were obtained from federally inspected slaughter facilities, and animals used in the experiment were treated according to standard ethical norms. The shortest sarcomeres were observed for longissimus dorsi from striploin, and the longest for infraspinatus muscle. Additionally, the influence of both cut and animal was observed.

This study investigates the effect of freezing rates on the spermatological parameters of frozen and thawed Saanen goat semen. Equilibrated semen was frozen at 4 different freezing rates from +5 °C to -150 °C (G10: 10 °C/min, G12: 12 °C/min, G15: 15 °C/min, and G24: 24 °C/min) and stored in liquid nitrogen until use. Semen samples were examined for sperm motility, defective acrosomes (FITC-PSA), and DNA integrity using TUNEL after dilution with extender A at equilibration and postthaw stage. There was no significant difference among the freezing stages in terms of DNA fragmentation (P > 0.05). DNA integrity was partially affected …

The study investigated effects of dystocia on milk production, reproduction, calf loss, and cow culling in a Turkish Holstein herd at the Agricultural Faculty, Ege University, İzmir, Turkey. Data were from 653 single calvings between 2006 and 2010. Considering a greater dystocia incidence in primiparous cows, data was divided in two; 223 primiparous and 430 multiparous calvings scored on a 1-to-5 scale. Scores were categorized into no dystocia and dystocia. With few related observations, all multiparous data were excluded since sample size for multiparous dystocic calvings was too small to make reliable estimates. Milk yields, days to first service, and …
