Standard limb, six lead (I, II, III, aVR, aVL, and aVF) electrocardiograms (ECGs) were recorded in 10 awake mature rock partridges (Alectoris graeca) and 10 chukar partridges (Alectoris chukar). Durations and amplitudes of P and T waves and QRS complexes, durations of P-Q and Q-T intervals, and mean heart rates were calculated from the lead II ECGs. All observable P and T waves were negative in aVR and aVL, whereas they were positive in all remaining leads. The most frequent forms of QRS complex were r-s (r-S) and q-r (q-R). A Q wave was observed in all aVR and aVL leads in both species. Chukar partridges had significantly higher amplitudes of P and T waves and QRS complexes than rock partridges. Mean heart rates were 310+/-15 beats/min and 317+/-19 beats/min for chukar partridges and rock partridges, respectively. Mean electrical axes, calculated from leads II and III, were -99+/-6.3 degrees and -95+/-1.7 degrees for chukar partridges and rock partridges, respectively. Clear ECGs were easily obtainable without anesthesia or sedation. 相似文献

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4–11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4–16) years in the non-brucellosis group (p < 0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55–5.28, p = 0.001), being male (OR, 4.5; 95% CI, 1.05–18.84, p = 0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002–1.02, p = 0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16–9.3, p < 0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection. 相似文献

The aim of this study was to evaluate prognostic and/or diagnostic factors of canine mammary tumors by immunohistochemically analyzing the expression of alpha basic crystallin (αB-c). For this, formalin-fixed, paraffin-embedded blocks of 51 naturally-occurring canine mammary tumors (11 benign and 40 malignant) were used. Tissue from eight normal canine mammary glands were served as a control. Immunohistochemically, in the control mammary tissues, a few luminal epithelial cells were αB-c positive but myoepithelial cells were negative. In benign or simple type malignant tumors, αB-c expression was observed in luminal epithelial cells while the myoepithelial basal cells were negative. In benign or complex type malign tumors, positive staining was predominantly found in the cytoplasm of epithelial cells. Immunoreactivity of αB-c was also observed in neoplastic myoepithelial cells. Statistically, the number of cells immunolabeled with αB-c was found to be significantly different among tissues from normal canine mammary glands, benign lesions, and malignant tumors (p < 0.05). αB-c immunoreactivity was higher in malignant tumors than the control mammary tissues (p < 0.001). Data obtained in the current study revealed a strong association between high expression levels of αB-c and primary mammary gland tumors in canines. 相似文献

In this study, strength and frictional properties of pecan was determined as a functional of moisture content. A pecan was loaded between two parallel plates to determine the rupture force, deformation, power and firmness required to initiate pecan rupture and determined static and dynamic friction. The tests were carried out at five moisture contents of 5.23?%, 10.36?%, 15.78?%, 20.08?% and 25.42?% db and three axes (X, Y, Z). Physical characteristics of the pecan such as mass, dimensions (length, thickness and width), geometric mean diameter, sphericity, volume, and shell thickness were determined. The force required to initiate nut rupture decreased from 112.321 to 98.723 N, from 82.872 to 63,988 N and from 80.093 to 62.758 N for the length, suture and width orientations of loading with an increase in moisture content. The highest toughness (20.460 Jmm??3) was obtained at moisture content of 25.42?% db. The firmness decreased to a minimum value when moisture content was increased from 5.23 to 10.36?% db and later increased as moisture content was increased further from 10.36 to 25.42?% db. The static and dynamic coefficients of friction on various surfaces, namely, plywood, mild steel and galvanized metal also increased linearly with increase in moisture content. The plywood surface offered the maximum friction followed by mild metal and galvanized metal. 相似文献

This experiment was conducted to investigate the effect of cafeteria (CF) and conventional (CN) feeding systems on feed intake,
feed preferences with respect to voluntary feed source intake, feed conversion rate (FCR) and fattening performance of native
Awassi lambs. Sixteen, 3 month old male lambs were used and kept individually for 70 days. Lambs in CF (n = 8) were offered to consume the main ingredients of barley, soybean meal (SBM), sunflower seed meal (SFM) and alfalfa straw,
separately, while lambs in CN (n = 8) were fed with a concentrate feed containing 11.34 MJ/kg ME, 17.53% crude protein with the mixture of the same feed sources
and alfalfa straw. The initial and final live weights of lambs were similar among groups (P > 0.05). Daily voluntary intake
of ash, fat and neutral detergent fiber (NDF) consumptions among groups were quite different during the experiment (P < 0.001).
Neither biweekly nor total results of voluntary protein intake between groups were not found statistically significant (P > 0.05).
From beginning to the end of the study, the proportional barley intake increased 34 to 43% but reduced for SBM intake from
37 to 23% for the lambs in CF. On the other hand, the SFM intake of lambs did not changed significantly during the experiment
and ranged between 2–5%. Lambs in CF did not consume SFM to meet their protein requirement and had 12.5% better total FCR
result than the lambs in CN (6.86 and 7.84, respectively) (P > 0.05). The difference of average DWG, total live weight gain,
final live weight of lambs in groups were similar (P > 0.05). In conclusion, Awassi lambs in CF can select a diet matching
their nutritional requirements from a group of feed sources in response to their growth period when compared to CN system
and better FCR result might help to decrease the feed expenses for fattening of native Awassi lambs. 相似文献

Effect of clinoptilolite on serum biochemical and haematological characters of broiler chickens during aflatoxicosis 总被引：4，自引：0，他引：4
Clinoptilolite (CLI, a natural zeolite) incorporated into the diet at 1.5 and 2.5 per cent were evaluated for their ability to reduce the deleterious effects of 2.5 mg total aflatoxin (AF) kg(-1)diet on broiler chickens from 1 to 21 days of age. In total 360 broiler chicks were divided into six equal treatment groups (control, AF, CLI (1.5 per cent), AF plus CLI (1.5 per cent), CLI (2.5 per cent) and AF plus CLI (2.5 per cent)). When compared with the controls, AF treatment significantly decreased serum total protein, albumin, inorganic phosphorus, uric acid, total cholesterol and the values of haematocrit, red blood cell counts, mean corpuscular volume, haemoglobin, thrombocyte counts, percentage of monocyte counts; increased values of white blood cell and heterophil counts. The addition of CLI (1.5 per cent) and CLI (2.5 per cent) to the AF -containing diet reduced the adverse effects of AF and should be helpful in a solution to the aflatoxicosis problem in poultry. 相似文献

The aim of our study was to evaluate the possible effects of whole-body electromagnetic field (EMF) exposure on reproduction in growing male rats. Male albino Wistar rats (2 days old) were exposed to EMF 1800 and 900 MHz for 2 h continuously per day for 90 days. Sham control was kept under similar conditions except that the field was not applied for the same period. After blood samples were collected, the animals were sacrificed 24 h after the last exposure and the tissues of interest were harvested. The mean plasma total testosterone showed similarity among the two study groups and was significantly higher than the sham control rats. The percentage of epididymal sperm motility was significantly higher in the 1800 MHz group (P<0.05). The morphologically normal spermatozoa rates were higher and the tail abnormality and total percentage abnormalities were lower in the 900 MHz group (P<0.05). Histopathologic parameters in the 1800 MHz group were significantly higher (P<0.05). In conclusion, the present study indicated that exposure to electromagnetic wave caused an increase in testosterone level, epididymal sperm motility (forward), and normal sperm morphology of rats. As a consequences, 1800 and 900 MHz EMF could be considered to be a cause of precocious puberty in growing rats. 相似文献

Conception of Jersey cattle in Turkey 总被引：1，自引：1，他引：0
To determine the effects of insemination season (IS; dry: May through October and rainy: November through April), lactation
number (LN; heifers, primiparous or multiparous) and their interaction on non-return rate (NRR), conception rate (CR) to first-service
and pregnancy loss (PL) of Jersey cattle in Turkey, over 1468 lactation records from 510 Jersey dairy cows were used. There
was an interaction between LN × IS on NRR, CR to first-service (p < 0.01) and PL (p < 0.05). The NRR and CR to first-service of heifers inseminated during dry season and of primiparous inseminated during rainy
season were higher (p < 0.01) than that of multiparous inseminated during both season. The NRR and CR of heifers and primiparous were higher (p < 0.05) than that of multiparous cows. The insemination of heifers during rainy season and of primiparous and multiparous
during dry season increased (p < 0.01) the PL compared to the inseminations of heifers during dry season and of primiparous during rainy season. The PL
was lower (p < 0.05) in primiparous than multiparous cows. The results demonstrate that the heifers have high fertility than the lactating,
especially multiparous and that IS appeared to have a measurable impact on traits relating to conception of Jersey cattle
in the each LN. 相似文献

A total of 142 samples of plants showing symptoms of Turnip mosaic virus (TuMV) were collected from fields planted to Brassicaceae and non‐Brassicaceae crops in the southwest Marmora region of Turkey, during the 2004?06 growing seasons. Using enzyme‐linked immunosorbent assay (ELISA) TuMV was detected in the main brassica‐crop fields of Turkey, with an overall incidence of 13·4%. TuMV was detected in samples from Brussels sprouts, cabbage, wild mustard, radish and wild radish, but not cauliflower or broccoli. The full‐length sequences of the genomic RNAs of two biologically distinct isolates, TUR1 and TUR9, were determined. Recombination analyses showed that TUR1 was an intralineage recombinant, whereas TUR9 was a non‐recombinant. Phylogenetic analyses of the Turkish isolates with those from the rest of the world showed that the TUR1 and TUR9 isolates belonged to world‐Brassica and Asian‐Brassica/Raphanus groups, respectively. This study showed that TuMV is widely distributed in the Asia Minor region of Turkey. 相似文献
