Preliminary characterization of Rhizobium strains isolated from chickpea nodules

A total of 28 Rhizobium strains from chickpea nodules were characterized on the basis of morphological, cultural and biochemical characteristics. Most strains produced abundant extracellular polysaccharides, were tolerant to 0.5 M NaCI (53%) and a temperature of 40oC (75%). The majority of the strains showed an intrinsic resistance to the antibiotics (ìg ml-1) streptomycin (100), kanamycin (50), erytromycin (30), chloramphenicol (200) and penicilin (25). In vitro antibiosis assays indicated that Rhizobium strains from chickpea nodules exercised an antagonism against Ascocyhta rabiei the agent of ascocyhta blight disease of chickpea

Effect of environmental heat stress on Kıvırcık ram sperm parameters

ΔΕΝ ΔΙΑΤΙΘΕΤΑΙ ΠΕΡΙΛΗΨΗThe relationship between environmental conditions and reproduction has been in sight of research. Therefore, there has been a growing interest in effect of climate change, global warming and subsequently environmental heat stress on gametes in last decades. Thus, the present study was designed to investigate the effect of environmental heat stress on Kıvırcık ram sperm parameters. In this study, semen samples (n=72) were collected from six mature rams during a 12-month study period. The temperature and relative humidity of animal box were controlled daily. The mean monthly temperature humidity index (THI) values were calculated to determine heat stress and control periods. According to the mean monthly THI values, the 36 of 72 ejaculates, which were collected between May and October, were classified as heat stress period samples. The others (n=36), which were collected between November and April, were considered as control period samples. The heat stress period sperm samples had lower sperm concentration, motility, viability, membrane integrity and higher abnormal sperm rate compared to control period sperm samples (P< 0.05). Semen volume, sperm DNA integrity and the ability of sperm to undergo acrosome reaction were detected similar between the heat stress and control periods. In conclusion, environmental heat stress was found deleterious for some sperm parameters in Kıvırcık rams.

Effects of gender and dietary date palm extract on performance, carcass traits, and antioxidant status of Japanese quail

This research examined effects of gender and dietary inclusion of date palm extract (DPE) on growth, carcass characteristics, oxidative status and serum characteristics of Japanese quail. One thousand chicks were allocated to five replicates of treatment and gender groups composed of 20 chicks. The treatments were a basal diet and four groups augmented with 0.25%, 0.50%, 0.75%, and 1.00% DPE. The interaction of gender and treatment was significant for bodyweight (BW) at 42 days, average daily bodyweight gain (BWG), feed intake (FI), weights of most carcass components, and the serum profile. Females had better performance to 42 days than males (P <0.05). In addition, females had higher hot and cold carcass weights, breast percentage, liver percentage, intestine percentage, total protein, albumin, triglyceride (TRIG), total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress indexes (OSIs) (P <0.001). Males had higher percentages of hot carcass, cold carcass and heart, and their levels of cholesterol (CHOL), high-density lipoprotein (HDL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values were greater than females (P <0.001). Birds fed 0.50% DPE grew faster, were more efficient, and had heavier live and carcass weights at 42 days than those fed the basal diet. However, treatment effects and their interaction with gender on growth, feed intake and the serum profile were unremarkable compared to the gender main effect. Dietary augmentation with 0.50% DPE might enhance the performance of quail between 14 and 42 days old

Effect of management system and dietary yeast autolysate on the performance, slaughter and carcass characteristics of partridges (Alectoris chukar)

This study was conducted to determine the effects of management system (a floor housing (FH) versus a free-range housing (FRH) system) and dietary yeast autolysate (Saccharomyces cerevisiae) (1% versus 2% dietary supplement) on the performance, slaughter and carcass characteristics of partridges (Alectoris chukar). A total of 480 (240 for each management system) one-day-old male partridge chicks were randomly allocated to a control group and the two dietary groups per production system, each containing 80 chicks. Each dietary group was then divided into five replicate groups of 16 chicks. The study lasted 112 days. In terms of growth performance, partridges reared under FRH management system had a lower average daily live weight gain (ADG), a significantly higher feed intake (FI), and feed conversion ratio (FCR) compared to the control group. However, partridges fed diets with yeast autolysate had a significantly higher ADG, lower FI, and an improved FCR compared to the control group overall. The gizzard, leg, and wing percentages of the partridges reared in the FRH system were found to be significantly higher than those of partridges reared in the FH system, while the breast and abdominal fat percentages were found to be lower. Dietary supplementation with yeast autolysate significantly increased the cold carcass yield and breast percentage when compared to the control group, while wing and abdominal fat percentages were decreased. In general, best performance was observed in the dietary supplementation group of 1% yeast autolysate in terms of growth and carcass parameters. When considering the fact that partridges are gamebirds, that housing poultry in cage production systems has been prohibited in recent years and that there are positive effects associated with using yeast autolysate as a prebiotic, it is recommended that a free-range production system should be used for partridge breeding, with the addition of 1% yeast autolysate to the diet of the birds.Keywords: Carcass attributes, gamebird, growth, housing syste

THE EFFECT OF PHYSICAL CHARACTERISTICS OF STADIUM ON SATISFACTION LEVELS OF FOOTBALL SPECTATORS' AGE GROUPS

The spectators are one of the most important basic articles of stadiums that are part of the sport industry. When a team of supporters and a winning team are involved, determining the reasons affecting the satisfaction levels of physical characteristics of stadiums according to age groups are important in terms of sports clubs and stadiums managers. This study was carried out in order to determine the physical characteristics of the stadiums and the satisfaction levels of the spectators watching football matches according to age groups. For this purpose, a questionnaire consisting of 17 questions was prepared by taking the opinion of 10 academicians and sector managers who are experts in sport management and sports marketing. Information and data were presented in simple and cross-tabular form, and Chi-square interest analysis was used in the evaluations. The main mass of the study is composed of the population of 15 years old and over who watch the match in four stadiums (Atatürk Olympic Stadium, BJK İnönü Stadium, FB Şükrü Saraçoğlu Stadium and GS Turk Telekom Arena) in Istanbul borders. Our sampling is 1025 people watching the match in these stadiums. Our research hypotheses were accepted at a significance level of 0.05. Accordingly, It was determined that spectators had an interest in their level of satisfaction with their use experience between age groups and the physical characteristics of stadiums. Ergonomic approaches, use comfort, health and safety considerations for people of all ages who will use the stadiums while constructing the physical characteristics of the stadiums are important for the creation of satisfaction levels.  Article visualizations

Chiari type I malformation with high foramen magnum anomaly

A 14-year-old male with a neck pain and hypoesthesia in the upper extremities was diagnosed with Chiari type I malformation (CMI) and syringomyelia. The posterior part of the occipital bone was removed via cranio-cervical decompression. The accuracy of measuring the posterior cranial fossa (PCF) and foramen magnum (FM) dimensions were evaluated and compared with the literature. The linear PCF and FM dimensions as well as volumes were measured using computed tomography (CT) images with different techniques. The volume data were compared with similar data from literature. Use of the posterior fossa approach remains controversial when treating patients with minor little brain stem dislocation, small PCF, and or incomplete C1, but the approach can easily be applied if FM and PCF sizes are known. Linear measurements that were assessed for concordance with CT measurements had the best agreement. Quantification of PCF volume and high FM should be taken into consideration for differential diagnosis of tonsillar herniation and prediction of surgical outcome in CMI
