Bu çalışmanın amacı Antalya ilinde sahipli kedi ve köpeklerdeki kene ve pire türlerinin yaygınlığını ortaya koymaktır. Kasım 2021 ile Ağustos 2022 tarihleri arasında, Antalya şehri sınırları içinde muayene için özel bir veteriner kliniğine getirilen sahipli 25 kedi ve 38 köpek, kene ve pire varlığı açısından incelendi. Köpeklerin ve kedilerin tüyleri pire tarağı ile taranarak toplanan pireler %70 alkol içeren şişelere toplandı. Kene türleri, ağız parçalarına zarar vermeden uçları küt olan küçük çelik pensler yardımıyla köpek ve kedilerin başlarından kuyruklarına doğru sistematik olarak toplandı. İlgili literatürler kullanılarak pireler ve keneler teşhis edildikten sonra fotoğrafları çekildi. Muayenesi yapılan 38 köpeğin 11 (%28,9)’inin Rhipicephalus sanguineus türü kene ile 3 (%7,9)’ünün R. sanguineus ve Ctenocephalides canis ile, toplamda %36,84 oranında enfeste olduğu tespit edildi. Toplam 25 kedinin 6 (%24)’sının Ctenocephalides felis türü pire ile, 2 (%8)’sinin C. felis ve R. sanguineus ile, toplamda %32 oranında enfeste olduğu görüldü. Pireler ve keneler sadece kedi ve köpekler değil aynı zamanda diğer hayvan ve insanlara birçok hastalığın taşınmasında rol oynadıkları için önemlidirler. Halk sağlığı açısından kedi ve köpeklerdeki ektoparaziter durum gözlenmeli ve kontrol altına alınmalıdır.

2024
Derya Balcı | Arife Sema Gün
Toprak toplulaştırması, parçalanmış parsellerin bir araya getirilmesidir. Tarım topraklarının toplulaştırılması veya parçalanmanın korunması toprak yönetim araçlarındandır. Toprak toplulaştırmasının olumlu yönleri ile parçalanmanın sorun olmadığı, yararlı da olabildiğini kanıtlayan çalışmalar bulunmaktadır. Ancak mevcut çalışmalar, toplulaştırmada veya parçalılığın sürdürülmesinde yerele özgü koşulların önceden değerlendirilmesi gerektiğini tavsiye etmektedir. Ayrıca toprak yönetimi araçlarından herhangi birine karar verebilmek veya her ikisine de devam edebilmek için sosyal, ekonomik, kültürel, yasal ve çevresel koşullar arasındaki bağlantıların da değerlendirilmesi gerekmektedir. Bu nedenle bu çalışmada, tarım topraklarının parçalanma biçimleri, nedenleri ve parçalanmanın olumlu-olumsuz etkileri literatüre dayalı olarak eleştirel ve nesnel bir şekilde incelenmektedir. Amaç, belirli bir alanda herhangi bir toprak toplulaştırma yaklaşımının benimsenmesiyle ilgili koşulları ve bağlantıları belirlemektir.

As a response to the evolving consumer demand for healthier food choices, ultrasound application in food processing emerges as a sustainable and green solution with no residual effects. This method, known for its cost-efficiency and sustainability, holds significant promise in meeting the increasing need for high-quality, chemical-free, and natural-tasting convenience foods in the ever-changing landscape of the food industry. Ultrasound, leveraging mechanical sound waves, spans across various frequencies: power ultrasound (20–100 kHz), high-frequency ultrasound (100 kHz-1 MHz), and diagnostic ultrasound (1–500 MHz). This study focuses on investigating the impact of ultrasound and combined treatments on food quality, summarizing their diverse applications across different unit operations such as texture and rheology, emulsification and homogenization, crystal formation and modification, dehydration and drying, fermentation, filtration, preservation and shelf-life extension, flavor enhancement, color and appearance, antioxidant activity, enzyme activity and food digestibility, bioavailability and bio-accessibility, and specific food divisions including unprocessed, minimally processed, processed, and ultra-processed foods, as well as culinary ingredients. It delves into their effects on technological and functional aspects of food products, explores emerging trends, offers possible recommendations in ultrasound technology for the food industry, while also recognizing existing challenges and limitations associated with ultrasound and related technologies.
Afficher plus [+] Moins [-]Effects of Farmyard Manure and Biochar Treatments on the Development and Water Use of Lettuce Under the Deficit Irrigation Regime
2024
Dilruba Erguler | Fatma Okyay | Omer Senol | Caner Yerli
In this study, the effects of different organic matter additives [soil (control), 20 ton ha-1 farmyard manure, 20 ton ha-1 biochar, and 10 ton ha-1 farmyard manure+10 ton ha-1 biochar] to the soil of lettuce grown with different irrigation water levels [100% (full irrigation), 75% (25% deficit irrigation), 50% (50% deficit irrigation), and 25% (75% deficit irrigation)] on water and irrigation water productivity efficiencies and plant characteristics were investigated. Among the organic matter additives, the biochar reduced the amount of irrigation water and actual evapotranspiration of lettuce and increased its marketable yield, thus the highest water and irrigation water productivity efficiencies were obtained from biochar treatment. Despite the decreasing marketable yield in the 50% irrigation treatment, the proportionally decreasing amount of irrigation water and actual evapotranspiration caused the highest water and irrigation water productivity efficiencies to occur in the 50% irrigation treatment. While the root diameter, root fresh and dry weights, stem diameter and length, head fresh and dry weights, marketable leaf number and yield, chlorophyll, and leaf relative water content of lettuce decreased with decreasing irrigation water levels, root length and membrane damage increased. The effects of organic matter additives on all of these physical-physiological properties, except root diameter and membrane damage, were found to be significant, and the biochar provided the most effective development of these parameters under the deficit irrigation regime. Considering that the yield and yield characteristics in 75% irrigation treatment do not decrease at a very significant level compared to full irrigation (100%) and that these decreases can be compensated by biochar and that the farmyard manure+biochar as alternative treatment is also effective in improving the decrease in yield parameters, treatment of 10 ton ha-1 farmyard manure+10 ton ha-1 to the soil at 75% irrigation water level was found to be recommended in lettuce cultivation.

2024
Marius D. Akissi | Clémentine A. Kouakou-Kouamé | Constant K. Attchelouwa Attchelouwa | Marc Lebrun | Corinne Teyssier | Jean-Christophe Meile | Florent K. N’guessan
This study aimed to investigate the volatile organic compounds (VOCs) variations during the spoilage of palm wine stored at ambient temperature and identify potential shelf-life markers. Palm wine collected from local tappers and resellers were stored at ambient temperature (28-30°C) for 96 h. At an interval of 24 h, VOCs variations were investigated using Solid phase Microextraction-Gas Chromatography-Mass Spectroscopy (SPME-GC/MS) method. Changes in sensory quality and potential flavour contributors were also explored. The sensory rejection time was found at 24 h and 48 h of storage for palm wines collected from the tappers and resellers, respectively. The first attribute to be spoiled was taste followed by odour and appearance. A total of 23 VOCs distributed in six chemical families were identified. Alteration of palm wine sample is characterised by an increase in concentration of alcohol (isoamyl alcohol, isobutanol and 1-octanol), aceti acid and acetoin, and a decrease in ester concentration (ethyl acetate and ethyl hexanoate). In the view to fight against the short shelf-life and develop new preservation methods, these compounds can be used as markers of spoiled palm wine.

Enes Karaman | Mehmet Şahin
Climate change-induced droughts have various negative impacts on different sectors, especially on agricultural sector. Altınekin District, where the research was conducted, has the lowest precipitation in Konya Province, therefore is expected to be most affected by drought. For sustainable use of water resources, each stage of agricultural production should be carried out within the framework of a specific program. With this study, knowledge level of farmers engaged in irrigated agriculture in Altınekin district regarding irrigation and irrigation programs they applied were determined through a face-to-face survey. Present findings revealed that 38.7% of the participant farmers are aged 50 years and over and a large proportion of them (54.7%) are primary school graduates. Participant farmers were all (100%) using groundwater resources in agricultural production and 88% of them stated that they did not receive any training on irrigation. While 32% of the farmers participating in the survey stated that they had knowledge about the concept of irrigation program, 68% reported that they did not have any knowledge. Incorrect and improper practices regarding efficient use of irrigation water in the region, especially regarding the irrigation program, were identified and solutions were proposed for these problems.

2024
Eylem Ezgi Fadıloğlu | Haluk Ergezer
The study was carried out to develop chicken patties by incorporating acorn flour as a meat replacer at 3%, 6%, and 9% levels in the formulation. For this purpose, the chemical (moisture, protein, fat, ash), pH, thiobarbituric acid (TBA), and color analyses in the raw and cooked chicken patties were analyzed. In addition, the cooking properties (cooking yield, diameter reduction, thickness reduction), functional properties (moisture and fat retention) and sensory properties were examined on cooked chicken patties. There were significant changes in the chemical, cooking, functional, and color properties of chicken patties with acorn flour. The moisture and protein values decreased, in both raw and cooked samples incorporated with acorn flour but fat level increased only in raw acorn flour added samples. Lightness (L*) and redness (a*) values decreased significantly. The addition of acorn flour caused an increase in b* values of raw samples and a decrease in cooked samples. Acorn flour was not effective in preventing lipid oxidation. The addition of acorn flour contents in chicken patties improved functional and cooking properties, decreased cooking loss, and increased moisture and fat retention. The use of acorn flour improved the quality parameters of patties, but the addition of acorn flour resulted in a darker color in patties. The use of acorn flour in chicken meatballs did not negatively affect sensory properties except color. In conclusion, acorn flour can be used as a filler and binder in chicken patties.
Afficher plus [+] Moins [-]The Effect of Different Grape Varieties and Adding Different Ratios of Mustard Seeds on the Phenolic Compounds, Antioxidant Capacity, and Bioaccessibility Values of Hardaliye under In Vitro Digestion
2024
Ayşe Semra Aksoy | Mustafa Yaman | Muhammet Arıcı
Hardaliye, grape-based fermented beverage, rich in antioxidant phenolic compounds. Bioaccessibility and antioxidant capacity of bioactive compounds in hardaliye, produced using varying amounts of mustard seeds (1%, 1.5%, and 2%) with Merlot and Papazkarası grape varieties, were evaluated under in vitro gastrointestinal digestion conditions. After digestion, Merlot and Papazkarası samples with 2% addition of mustard seed showed significantly higher total phenolic compounds (TPC) (358.48±14.73 and 89.01±2.42 mg GAE/L, respectively) compared to other samples (P<0.05). 2% mustard seed added Merlot samples resulted in the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC) values (19.06±3.91 and 9.96±1.83 mmol TEAC/L, respectively) which differed significantly from other samples (P<0.05). The Merlot sample with 2% addition of mustard seed showed significantly higher TPC, total flavonoid compounds (TFC), DPPH, and CUPRAC bioaccessibility values compared to other Merlot samples (P<0.05). For Papazkarası samples with 2% mustard seed addition, significant differences were observed only in terms of TPC and TFC bioaccessibility values (15.87±2.30% and 15.27±1.29%, respectively) compared to samples with 1% and 1.5% mustard seed addition (P<0.05). The study demonstrated that the bioaccessibility of bioactive compounds in hardaliye can vary depending on the grape variety and to some extent, the use of mustard seed. This suggests that the food matrix and interaction with other food matrices in the environment can affect the stability and bioavailability of bioactive compounds during simulated digestion.
Afficher plus [+] Moins [-]Moisture Optimization and Energy Saving Effects of Combined Organic Acid and Surfactant Inclusion in Pelleted Feed Production
2024
Duygu Budak | Kazım Bilgeçli
The purpose of the present study was to determine the effects of inclusion of an organic acid and surfactant (OS) combination on moisture optimization and energy sparing in the production of pelleted compound feeds for dairy and beef cattle. The trial was carried out in two independent private commercial feed factories (factories A and B) producing cattle feed in pellet form. Each factory produced 21 tons of commercial cattle feed (7 batches; 3 tons per batch); factory A, a dairy feed containing 2620 kcal/kg metabolizable energy (ME) with 18.90% crude protein (CP); and factory B, a fattening feed containing 2550 kcal/kg ME with 13.00% CP. Batches for the treatment groups were prepared by adding 0.5, 1.0 and 1.5 kg/ton of OS (Fylax flow) respectively to these basal feeds in the mixer. The moisture retention capacity during pelleting process of all three OS supplemented feeds increased in comparison to the basal feed, whilst moisture content of the finished feeds and energy consumed for production decreased significantly. It was observed that increasing the OS supplementation to 1.5 kg could further increase the moisture retention capacity and moisture content in pellet production compared to the feeds supplemented with 0.5 and 1.0 kg OS, due to the lower power rating of the equipment. It has thus been concluded that adding 0.5, 1.0 and 1.5 kg of OS to commercial compound feeds for dairy resulted in a profitable production with good moisture optimization and energy savings during pelleting.

Aicha Blama | Zineb Fedjer | Amokrane Mahdeb | Azzedine Mazari
The botanical heritage of a region is an important resource for local people, which allows them to treat themselves with plants that have already been experienced from generation to generation for their benefits and effectiveness. The aim of this study was to highlight the different uses of lentisk pistachio products in the region of Jijel (Algeria). Systematic surveys have been carried out among different categories of people, by age group; have shown a growing interest in the use of medicinal plants. Two approaches (observation, and interview) were used to support this study, with an ethnobotanical worksheet, to obtain other recipes and more information on lentisk benefits and uses. The survey data processing showed that the lentisk is used for therapeutic purposes, to treat diseases of the skin (29%) and respiratory system (28%). The main and most used part of the plant is its berries. The plant is harvested in a spontaneous state and the picking of berries is done from November (in winter). Oil extraction is the principal preparation (72%). The use of resinous gum was not mentioned. Ten percent of surveys gave culinary recipes for some traditional meals preferred by Jijelians. The current study highlighted the ancestral practices and uses of the lentisk by Jijelians. It is necessary to develop this niche and promote its value chain in order to consolidate the economy of the local population.
