Effect of seasonal conditions on oestrus occurrence and postpartum period in Anatolian water buffaloes     

Aksoy M  Kaya A  Uçar M  Lehimcioglu N  Tekeli T 《DTW. Deutsche tier?rztliche Wochenschrift》2002,109(9):416-418

Oestrus and calving records of Anatolian buffaloes were analyzed to investigate influence of climatic conditions on oestrus occurrence and postpartum period. Oestrus records showed a seasonal pattern concentrated between July and September which is the warmest period of the year. Likewise, more than half (52.7%) of the total calvings occurred between May and August. Month of calving significantly influenced the length of calving to first oestrus interval and open period (P < 0.01). The average length of open period was significantly shorter in autumn and summer calvers compared to those calved in spring and winter (P < 0.05) during long days. The humidity rate was negatively correlated with both calving to first oestrus interval and open period (P < 0.05). In conclusion, exposure to high environmental temperatures around 20 degrees C exerted no suppressive influence on ovarian activity in Anatolian buffaloes. Although humidity rate (P < 0.05) and ambient temperature (P < 0.01) was found to be correlated with the duration of postpartum period, day length might be the main factor regulating reproductive biorhythm and postpartum events in Anatolian buffalo cows.  相似文献   

Mammary fibroadenoma in a lamb     

M. Yavuz Gulbahar  Tolga Guvenc  Murat Yarim  Yonca B. Kabak  Yuksel Sozgen 《Journal of veterinary science (Suw?n-si, Korea)》2007,8(4):423-425

A fibroadenoma was diagnosed in the left udder of a 3-month-old female Chios lamb. No recurrence was observed after surgery. Grossly, the tumor had a whitish-gray lobular appearance, and the lobules were interlaced with thin septa. Microscopically, the tumor was composed of proliferating fibroepithelial tissue, including differentiated ducts lined by whorls and interlacing bundles of abundant loose fibrovascular stroma. Immunohistochemistry revealed the ductal epithelium to be positive for pancytokeratin (AE1/AE3) and loose fibrovascular stroma was positive for vimentin and basal cells covering the ductal epithelium of alpha-smooth-muscle actin. Immunostaining for the estrogen and progesterone receptors was negative. A diagnosis of mammary fibroadenoma was made based on the histological and immunohistochemical findings.  相似文献   

Effects of varying nitrogen doses on yield,yield components and artemisinin content of Artemisia annua L.     

Menşure Özgüven  Bilge Şener  Ilkay Orhan  Nazım Şekeroğlu  Muzaffer Kirpik  Murat Kartal  Ipek Peşin  Zülküf Kaya 《Industrial Crops and Products》2008,27(1):60-64

Artemisia annua L. is an aromatic-antibacterial herb that destroys malarial parasites, lowers fevers and checks bleeding, and of which the secondary compound of interest is artemisinin. The objective of the present study was to determine yield, yield components and artemisinin content of A. annua L. grown under four nitrogen applications (0, 40, 80 and 120 kg ha⁻¹) in the Çukurova region of Turkey in 2004 and 2005. Field trials were conducted at Çukurova University, Agricultural Faculty Field Crops Department. In the study, plant height, number of branches, fresh herbage yield, dry herbage yield, fresh leaf yield, dry leaf yield, essential oil content and artemisinin content (by high performance liquid chromatography, HPLC) were examined. By analysis of variance, nitrogen doses had no any statistical effect on the traits investigated except for artemisinin content. Artemisinin content of the dried leaves were significantly affected by nitrogen applications, which varied from 6.32 to 27.50 mg 100 g⁻¹. Contents were from 120 and 80 kg ha⁻¹ nitrogen for the years of 2004 and 2005, respectively.  相似文献   

A retrospective study of gastrointestinal disorders in a predominantly Austrian leisure horse referral hospital population     

V. Gunes  A. C. Onmaz  A. Pavaloiu  G. Kaya Karasu  R. van den Hoven 《Equine Veterinary Education》2022,34(9):467-472

The aim of our retrospective study was to produce and analyse epidemiological data on gastrointestinal (GI) disorders of Austrian leisure horses. Case records of horses referred to the Equine Clinic of the Veterinary University of Vienna were collected from an electronic hospital information system using its search options. All cases reported to have suffered a GI disorder between March 2003 and February 2015 were selected. In this period of 4314 days, data of 1833 GI cases, mostly accompanied by colic signs, were analysed. The vast majority of our GI cases appeared in the abdominal parts of the GI tract 96% (1760/1833) while just 1.3% (24/1833) could be definitively attributed to oesophageal disorders, whereas in 2.7% (49/1833) of the cases a definitive diagnosis could not be made. The highest prevalence of GI disorders was seen in July and October/November. A breakdown of figures for cases clustered under the colic syndrome showed that colon impactions in left ventral large and/or pelvic flexure (35%) were the major problem followed by gastric disorders (18%), spasmodic colic (9%), enteritis (7%), caecal tympany (6%); caecal impaction (4%), colitis (3%), abnormal anatomical positions of large colon including complete and partial strangulation/volvulus, nephrosplenic entrapment of the left ventral and dorsal colon and right dorsal displacement of the large colon (3%) and small intestinal volvulus (2.7%). In 12% of the cases, the cause of the abdominal discomfort was likely idiopathic paralytic ileus. The searching tool of the electronic patient data also brought up cases with malabsorbtion/IBD syndrome and GI ruptures, both these contributed less than 1% of the referred GI cases. Results suggested that the causes of colic are diverse, but the major reasons for referred cases of colic in the east Austrian horse population are large colon impaction or displacements. Seasonal distribution and specific causes of gastrointestinal disorders should be considered essential components of the initial clinical assessment of horses presenting with colic.  相似文献   

The forest garden system of Saparua island Central Maluku, Indonesia, and its role in maintaining tree species diversity     

M. Kaya  L. Kammesheidt  H.-J. Weidelt 《Agroforestry Systems》2002,54(3):225-234

The dusuns of Central Maluku which improve fallows by planting spice trees such as clove (Syzygium aromaticum syn. Eugenia aromatica), nutmeg (Myristica fragrans), or coconut (Cocos nucifera) and tending spontaneous regeneration, are an example of a species-rich forest garden system in the eastern hemisphere of the Indonesian archipelago. In this paper we report the influence of site conditions, as slope inclination, soil type, and soil depth, on species composition, tree species diversity, and stand structure in old dusuns in four villages on Saparua, a small island south of Seram. In addition, we compared the floristic composition and stand structure of old dusuns with those of primary forest and advanced fallow vegetation (∼15-yr old). Soil conditions, particularly the depth of the mineral soil layer, and the relief have a major influence on species selection in dusuns. The most common species in old dusuns were absent both in primary forest and forest fallow. Floristic similarity between old dusuns and the unmanaged stands was low. However, in two study villages species richness of old dusuns was similar to that of the primary forest. Old dusuns showed an open structure with an average reduction of basal area by about half compared to the primary forest. Less than half of all individuals found above 10 cm DBH in old dusuns were planted. Only very few species were exclusively planted. Most species were both planted and emerged from spontaneous regeneration. The results indicate the important role of spontaneous regeneration in this forest garden system. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献   

Variation in crushing strength and some related properties of a red pine     

Fikret Kaya BScFE  MScFE. Ph. D. candidate  Ian Smith BSc.  MSc.  PhD.  PEng.  FIWSc. 《Wood Science and Technology》1993,27(3):229-239

Summary Below-crown radial and height variations in maximum crushing strength parallel to grain, relative density and tracheid length of an immature, 55 year old, red pine were studied. All properties showed pronounced trends with radial age and increased from pith to bark. A radial age of 16 years was estimated as the age from which mature stem wood is formed. All properties studied varied with height above ground. Strong correlations were observed among properties. The study tree exhibited noticeably lower average crushing strength than is reported in the literature for wood from mature red pines.This work was undertaken with financial support from Karadeniz Technical University, Trabzon, Turkey, and the Natural Sciences and Engineering Research Council of Canada, Operating Grant 0GP0004417  相似文献   

Pharmacokinetics of enrofloxacin after intravenous and intramuscular administration in Angora goats.   总被引：1，自引：0，他引：1  

M Elmas  B Tras  S Kaya  A L Bas  E Yazar    E Yarsan 《Canadian journal of veterinary research》2001,65(1):64-67

Pharmacokinetics and bioavailability of enrofloxacin were determined after single intravenous (IV) and intramuscular (IM) administrations of 5 mg/kg body weight (BW) to 5 healthy adult Angora goats. Plasma enrofloxacin concentrations were measured by high performance liquid chromatography. Pharmacokinetics were best described by a 2-compartment open model. The elimination half-life and volume of distribution after IV and IM administrations were similar (t1/2beta, 4.0 to 4.7 h and Vd(ss),1.2 to 1.5 L/kg, respectively). Enrofloxacin was rapidly (t1/2a, 0.25 h) and almost completely absorbed (F, 90%) after IM administration. Mean plasma concentrations of enrofloxacin at 24 h after IV and IM administration (0.07 and 0.09 microg/mL, respectively) were higher than the minimal inhibitory concentration (MIC) values for most pathogens. In conclusion, once-daily IV and IM administration of enrofloxacin (5 mg/kg BW) in Angora goats may be useful in treatment of infectious diseases caused by sensitive pathogens.  相似文献   

Genetic and morphologic diversity of <Emphasis Type="Italic">Echinochloa crus-galli</Emphasis> populations from different origins     

Emine Kaya Altop  Husrev Mennan 《Phytoparasitica》2011,39(1):93-102

Echinochloa crus-galli (L.) P. Beauv. (barnyardgrass) is an annual weed that is native to Asia and found throughout the world. The broad ecological tolerance and competitive ability of E. crus-galli makes it the most important weed species in rice. Genetic studies of plants are becoming increasingly common because reliable information is necessary to better understand population dynamics, occurrence of herbicide resistance, and demographic data. Echinochloa crus-galli populations from 34 different locations in Turkey were compared with respect to morphological differences and genetic variation. For morphological variation, five seeds of each population were sown in pots and grown in a screenhouse using a randomized block design. Morphological parameters such as germination speed, flowering time, leaf area, plant height, spikelet length, above-ground biomass, root dry weight and number of seeds were measured. Distinct differences among populations with respect to hierarchical cluster analysis were observed. Genetic variations among populations were performed using random amplified polymorphic DNA (RAPD) markers. The seven RAPD primers amplified 55 bands whose molecular weight varied between 200 and 4000 bp. The percentage of polymorphic bands was 74.54%. Results showed high morphological and genetic variability among individual genotypes within geographic locations. Phenotypic and genetic variability among E. crus-galli populations would be influenced by agricultural practices, crop characteristics, geographic location and herbicide pressure. Differences between weed populations may affect response to chemical or biological control.  相似文献   

Effect of improved fallow on crop productivity, soil fertility and climate-forcing gas emissions in semi-arid conditions     

Nicola M. Hall  Bocary Kaya  Jan Dick  Ute Skiba  Amadou Niang  Ramadjita Tabo 《Biology and Fertility of Soils》2006,42(3):224-230

The impacts of fallow on soil fertility, crop production and climate-forcing gas emissions were determined in two contrasting legumes, Gliricidia sepium and Acacia colei, in comparison with traditional unamended fallow and continuous cultivation systems. After 2 years, the amount of foliar material produced did not differ between the two improved fallow species; however, grain yield was significantly elevated by 55% in the first and second cropping season after G. sepium compared with traditional fallow. By contrast, relative to the unamended fallow, a drop in grain yield was observed in the first cropping season after A. colei, followed by no improvement in the second. G. sepium had higher foliar N, K and Mg, while A. colei had lower foliar N but higher lignin and polyphenols. In the third year after fallow improvement, a simulated rainfall experiment was performed on soils to compare efflux of N₂O and CO₂. Improved fallow effects on soil nutrient composition and microbial activity were demonstrated through elevated N₂O and CO₂ efflux from soils in G. sepium fallows compared with other treatments. N₂O emissions were around six times higher from this nitrogen-fixing soil treatment, evolving 69.9 ngN₂O–N g⁻¹soil h⁻¹ after a simulated rainfall event, compared with only 8.5 and 4.8 ngN₂O–N g⁻¹soil h⁻¹ from soil under traditional fallow and continuous cultivation, respectively. The findings indicate that selection of improved fallows for short-term fertility enhancement has implications for regional N₂O emissions for dry land regions.  相似文献
