2023
Hakkı Mümün Ay | Adnan Söylemez | Nihal Güneş Ay
In recent years, intensive legal regulations aimed at the production of urban areas in Türkiye, the phenomenon of migration, the spread of higher education, abnormal cost increases in agricultural activities have accelerated urbanization. Parallel to the increase in the urban population, the food supply remains insufficient. The inability to increase the production of food products brings with it problems such as malnutrition, inflation, foreign trade deficit, food security. The natural areas harbored by rural and urban areas are shrinking and being destroyed by the pressure of rapid urbanization. In addition to the abandonment of rural areas, the food crisis that has arisen as a result of the intervention of the urbanization process in agricultural areas has increased the responsibility of the central government and municipalities. In order to meet the food needs of the population and implement sustainable agricultural policies, municipalities are taking different and innovative approaches. Municipalities are making direct and indirect attempts to provide people with cheap and reliable food. In this study, the activities carried out by the municipalities in Türkiye to support sustainable agriculture and their economic and social effects were examined.

Worlah Yawo Akwetey | Awuni, Bernard Yaw | Yeboah Elizabeth
Fermented sausages are stable meat items typically prepared from comminuted mixtures of meat, spices, and salts and permitted to ripe under controlled conditions, where bacteria produce lactic acid quickly and reliably from added sugars in the form of dextrose. This study assessed the possibility of using fresh ripe plantain (FRP) in semi-dry fermented beef sausages. FRP was used at 0% (T0), 5% (T1) and 10% (T2). A fourth treatment with 0.5% dextrose without any FRP (T3) was produced. The products were evaluated for proximate compositions, pH, cooking loss as well as sensory attributes. No significant differences existed between T0, T1, T2 and T3 in terms of appearance, flavor, aftertaste and texture, however significant differences were recorded in tenderness, juiciness and acceptability. Cooking loss and water holding capacity ranged between 31.83 (T0) to 36.53 (T3) and 4.40 (T3) to 14.74 (T2) respectively. The pH recorded after 36 hours of fermentation ranged from 4.20 (T3) to 5.36 (T0). Using FRP resulted in appreciable decreases in costs of producing semi-dry fermented beef sausages from 20.50 to 16.46 Ghana Cedis per kg. It was concluded that fermented beef sausages could be made with 5% fresh ripe plantain without any adverse effects on consumer acceptability.

2023
Atakan Karakaya | Ali Gücükoğlu
This study aimed to investigate the presence of Salmonella spp. in chicken doner samples, both ready for consumption and sold in packages in a modified atmosphere, using classical culture technique and the MALDI-TOF method by determining the antibiotic resistance profile structure through the disc diffusion method by determining the serotypes of the isolates through mPCR. Between September and November 2019, 150 ready-to-eat chicken doner samples (75 of them ready to consume, the other 75 packed in a modified atmosphere) were analyzed. It was found that 23 of the 150 (15.3%) samples analyzed were contaminated with Salmonella spp. 73 isolates were obtained from 23 positive samples. Of these 73 isolates, 33 were found to be Salmonella spp. positive. In serotyping, all 33 isolates were determined to be S. infantis. In the antibiotic resistance profile, 30 of theisolates were resistant to chloramphenicol, 24 to gentamicin, 21 to ampicillin, 20 to trimethoprim-sulfamethoxazole and ciprofloxacin, 18 to tetracycline and amoxicillin-clavulanic acid, and 13 to cefoxitin. As a result, the isolation of Salmonella spp. from the samples and their resistance to different antibiotics were evaluated as potential sources of problems in the context of foodborne infectious diseases.

İlker Gül | Yusuf Cufadar
The aim of this study is to determine the effects of adding different levels of red pepper oil to quail diets on performance, slaughtering characteristics, and some serum parameters. For this purpose, a total of 300-day-old and mixed-sex quail chicks were randomly assigned to 5 treatment groups with 6 replications of 12 chicks each. Experimental animals were fed for 35 days with 5 different diets prepared by adding 0, 300, 600, 900 or 1200 mg/kg red pepper oil. During the experiment, quails were given ad-libitum feed and water. According to the results of the experiment, the effect of adding red pepper oil to the diet on the performance, carcass traits and visceral weights of the quails was statistically insignificant. Triglyceride and TAS concentrations of serum were significantly affected by the addition of red pepper oil to the diet. The highest triglyceride and TAS levels in the group with 300 mg/kg red pepper oil added; however, the lowest triglyceride and TAS levels were obtained in the groups supplemented with 600 mg/kg and 1200 mg/kg red pepper oil, respectively. According to this study findings, it can be said that the addition of red pepper oil to the diet in growing quails has a positive effect on serum triglyceride and TAS values when used between 300 mg/kg and 600 mg/kg in the diet, without adverse effects on performance and carcass characteristics.

Although concepts such as global climate crisis and global warming, which are frequently used with the industrial revolution, did not make people very nervous before, countries and scientists have begun to think more about this issue today. Recently, with this climate crisis, another crisis deepened by Covid-19, wars and economic problems has been brought to the agenda: The Global Food Crisis. The possibility that people's economic and ecological conditions cannot reach enough and always the same amount of food is becoming increasingly unsettling. With these conditions, it is foreseen that people will include edible herbs in their natural habitats in their menus, as they did in the countryside from time immemorial. There are different studies on natural edible herbs in different disciplines, but there are very few studies evaluating these herbs from a gastronomic point of view. Studies such as the dissemination of traditional knowledge about natural edible herbs and the preparation of recipes for foods and beverages made with these plants are studies that can also find response in fields such as economy, sociology, tourism, health and agriculture. Carrying out all these studies in combination can also contribute to healty and gastronomy-themed tourism. For this reason, in our study, studies on natural edible herbs in Türkiye were compiled and evaluated in a way to cover ancient times and today and different disciplines. As a result of the evaluation, natural edible plants that came to the fore in previous studies and our study were determined and information about the food parts of these plants, their usage areas and usage patterns were given.

For commercial aquaculture, the obtainment of all-female salmonid populations is important in fish farms. After freezing process, variable spermatozoa maturity, higher sperm concentration, low sperm quality, and reduced fertilization success have been observed in sex-reversed female rainbow trout. For these reasons, the objective of this study was to assess effect of dilution rate and supplementation of a N-(2-Mercaptopropionyl)-Glycine (MPG)-based extender on sperm motility and fertilizing capacity of sex-reversed rainbow trout (Oncorhynchus mykiss). The supplementation of MPG [0 (control, 0), 1 mM; 2 mM; 4 mM] to extenders and dilution ratio (1:9, 1:15 and 1:25) were tested in sex-reversed female rainbow trout spermatozoa during cryopreservation. For thawing, the straws (0.5 ml) were placed in a water bath at 37°C for 30 s. Our results showed that the best concentration of MPG was 2 mM for post-thaw motility duration (120.67±9.07%), fertilization (62.67±3.10%) and hatching rate (54.33±3.10%) at 1:15 dilution rate. Overall, MPG provided improvements during cryopreservation process and could be used as protective agent.

Güneycan Akyol | Muzaffer Denli
The purpose of this study was to determine the dietary effects of fruit pulps (dried tomato, apple and grape) on the performance and egg quality characteristics of laying hens. In this trial, 196 Lohmann sandy layers 25 weeks of age were distributed into four groups with seven replicates for 9 weeks. Trial groups fed following diets, control group basal diet (no additive), 4 % dried tomato pulp, 4% apple pulp and 2.5% grape pulp. Feed conversion rate was not affected by any addition of fruit pulps throughout the trial. The dietary inclusion of dried tomato pulp increased feed consumption, egg weight and egg production and decreased egg yolk malondialdehyde (MDA) levels on day of 1 compared to the control. Egg yolk MDA level was decreased with the addition of 4% tomato and apple pulp to the diet, but increased with the addition of 2.5% grape pulp to the diet on the day of 28. Moreover, the addition of dried tomato pulp to the basal diet significantly increased egg weight and egg yolk yellow color (a). As a result, this study provides evidence that adding up to 4% tomato pulp to diets may be used without adverse effects on laying hens’ productivity and may improve egg quality characteristics by decreasing MDA levels in the yolk.

Manal Al-hajj | Aysel Kekillioğlu
Research is achieved for the sake of contribution towards science and getting information systematically, starting from the collection of data, passing through interpretation and final evaluation of these data and all that, in an organized manner which is called scientific research. Biotechnology includes the application both of older biological knowledge, which is based on structures, functioning, and development of animals and plants in their ecological setting, and of newer approaches, which are based on an understanding of genetics and on the cellular and subcellular processes. The development of biotechnology has given society an awesome new power and an equally awesome responsibility to use it wisely. Biotechnology is being applied in different areas of science such as agriculture, health, the environment, and many other aspects of science and industry. Most of these applications and developments are centered in the developed countries and the research is established by these notions. Currently, it has been obvious that biotechnology is crucial for notion’s economic growth and sustainable development. Yemen, as one of the most developing countries, is suffering to emerge molecular biotechnology research in universities and research units. This is because of many aspects that affect the soceity, goverment, and ultimatly the entire country, including society, human resources, facilities, infrastructure and environment resources, and stability. To conclude, the researchers in Yemen are surrounding by many challenges, which are starting in society and ending up in the laboratory. The research has very low priority on a long list of priorities such as food, stability, security, and healthcare. All the challenges can be solved, but it will need a more educated society and serious government policy toward research as a tool to build a strong society.

Our current research aimed to investigate the impacts of the use of indigenous yeast Saccharomyces cerevisiae with different amounts of Lachancea thermotolerans yeasts in mixed culture on the general composition, aroma compounds, sensory analysis and yeast growth of cv. Emir wine. The utilization of L. thermotolerans in mixed cultures reduced the total acidity of wines from 5.40 to 5.19 g/L (as tartaric acid). The acidity of high acid grapes musts obtained from various viticulture areas can be relatively decreased in wine production. In addition, there may be a slight decrease in the amount of ethyl alcohol. On the other hand, increasing the inoculum level of L. thermotolerans led to an increase in the amount of higher alcohols. However, the concentration of esters declined with the higher inoculum levels. According to the sensory evaluation, the most preferred wine was the one obtained with co-inoculation of S. cerevisiae and L. thermotolerans strains at the level of 5×106 and 1×108 cells/mL, respectively. As a result, it can be said that the use of L. thermotolerans yeast in different inoculum levels has a positive effect on wine fermentation.

Dibyendu Biswas
The congenital disability, atresia ani or atresia ani et recti or recto-vaginal fistula, is one of the most common types of congenital malformation disability. A 45-day-old male cross-breed calf was admitted to Patuakhali Science and Technology University's Veterinary Teaching Hospital with complaints of leaking feces through the umbilicus and was clinically confirmed as a recto-umbilicus fistula. This congenital condition was corrected successfully by making an artificial opening in the lower right abdominal wall. Corrective surgery was the only successful technique for repairing the recto-umbilicus fistula. The prognosis for surgical correction of the recto-umbilicus fistula in a cross-breed calf was indicated to be good.
