Domuz ayrığı (Dactylis glomerata L.) yaygın olarak yetiştiriciliği yapılan, ekonomik açıdan önemli çok yıllık bir buğdaygil yem bitkisidir. Bu araştırma, Ege Tarımsal Araştırma Enstitüsü yem bitkileri ıslah programı kapsamında geliştirilen elit domuz ayrığı klonlarının akrabalık derecelerini ve genetik çeşitliliğini belirlemek amacıyla yürütülmüştür. Çalışmada 32 genotip ve 24 SSR primeri kullanılmıştır. Moleküler analiz sonucunda SSR primerleri toplamda 126 allel üretmiştir. Allel sayısı 3 ila 7 arasında değişmiş ve lokus başına düşen ortalama allel sayısı 5,25 olarak bulunmuştur. Elde edilen allel büyüklükleri ise 101 bp ile 354 bp arasında değişmiş ve polimorfizm oranı her primer için %100 olarak gerçekleşmiştir. Bireyler arasında uzaklık derecesi Jaccard genetik uzaklık katsayısı kullanılarak elde edilmiş ve 0,21 ile 0,84 arasında değişmiş ve genetik çeşitlilik seviyesi yüksek bulunmuştur. Genotiplerden elde edilen 126 allelin 28’nin nadir alleller olduğu ortaya çıkmıştır. Jaccard genetik uzaklık katsayısı kullanılarak yapılan neighbor-joining analizi sonucunda oluşturulan dendrogram 3 ana gruba ayrılmıştır. A grubu en büyük grubu oluşturmuş ve bünyesinde 15 genotip barındırmıştır. B grubu orijini aynı bölge olan 13 genotiple ikinci büyük grubu oluşturmuştur. C grubu ise en küçük grup olup orijini Türkiye’nin kuzeyi olan genotipleri barındırmıştır. Moleküler analizler domuz ayrığı genotiplerinin önemli derecede genetik varyasyon taşıdığı ve ıslah programı için değerli kaynaklar olduğu ortaya çıkmıştır. Bunlara ek olarak, SSR tekniğinin domuz ayrığı genotiplerini moleküler olarak tanımlamada oldukça uygun ve etkili bir teknik olduğu sonucuna varılmıştır.

Yapılan çalışmada, tarçın yağının yavru alabalık (Oncorhynchus mykiss) yemlerine ilavesinin balıklarda büyüme performansı, yem değerlendirme ve kan parametreleri üzerine etkileri araştırılmıştır. Bu kapsamda 0 mL/kg (TY0), 1 mL/kg (TY1), 2 mL/kg (TY2), 4 mL/kg (TY4)ve 10 mL/kg (TY10) olmak üzere 5 farklı konsantrasyonda tarçın yağı içeren deneme yemleri hazırlanmıştır. 60 gün sürdürülen çalışmada ağırlıkları (10,68±0,35 g)olan yavru alabalıklar kullanılmış olup deneme 3 tekrarlı olmak üzere 100 L hacimli akvaryumlarda yürütülmüştür. Besleme denemesi neticesinde tarçın yağı içeren yemlerle beslenen grupların kontrol grubuna nazaran büyüme ve yemden yararlanma performanslarının önemli ölçüde arttığı gözlenmiştir. Deneme sonunda alınan kan numunelerinin analizi sonucunda, tarçın yağıyla beslene balıkların eritrosit ve hemoglobim miktarları, hematokrit oranları önemli ölçüde artış göstermiştir. Ayrıca tarçın yağı balıkların serum glikoz, trigliserit ve kolesterol miktarını azaltırken, toplam protein ve albümin miktarını arttırmıştır. Çalışma bulgularına göre alabalık yemlerine 4mL/kg tarçın yağı ilavesinin balıkların büyüme performansı, yem değerlendirme ve sağlık kriterleri olumlu yönde etkilediği gözlenmiştir.

Dielectric properties of materials are used for evaluating their interactions with electromagnetic energy. Dielectric properties of food materials are required for various applications in food industry such as microwave (at 915 or 2450 MHz), radio wave (at 13.56, 27.12 or 40.68 MHz) and magnetic field processing. In order to understand the response of food materials to electromagnetic energy, dielectric parameters must be determined as a function of frequency, temperature, composition and moisture content. In this review, the dielectric properties of different food groups were listed depending on temperature and frequency ranges. In addition to the literature data of dielectric properties, the penetration depths of microwave or radio wave through food groups were calculated. The effects of temperature and composition (mostly moisture content) on dielectric properties depend on the type of the food and sometimes on frequency. However, the effect of frequency is constant; increased frequency decreased dielectric constant, loss factor and penetration depth. The lowest calculated penetration depth belonged to the fish surimi gel as 3.39 mm at microwave frequency whereas they were high generally for fats, oily seeds and flours (max was 372602 mm for corn flour). It appears that dielectric properties of foods should be investigated further depending on the interactions between frequency, temperature and composition. And then, dielectric heating based on the aim of the process can be applied accordingly. Besides, it appears that the moisture content and especially the dipole rotation and the conductivity movements of the molecules in free water content of the food are some of the most critical factors influencing the dielectric properties of food materials.

The growth of fish in intensive fish farming is carried out completely by the feeds supplied from externally. Different ingredients are used in feed production. The nutritional content of these ingredients is checked when purchased or brought to the factory. These ingredients are then stored until feed production. Storage duration and storage temperatures directly affect the freshness criteria of feed ingredient materials. Especially when high-energy ingredients with high levels of fat are stored in poor storage conditions, the fats in the ingredients are oxidized, therefore the peroxide number increases and the ingredient becomes bitter. Oxidation not only destroys the lipids in fish feeds but also vitamins. Slow growth, poor feed evaluation, color darkening, lethargy and deaths have been reported in fish fed with diets that are oxidized and inadequate in vitamin E. In this study, oxidation levels of fish feed ingredients were determined due to different storage conditions. Generally, the number of peroxides increased due to the increase in storage time and temperature, depending on the type of raw materials and oil content.

In this article, the production and consumption values of poultry meat are discussed in order to evaluate the entrepreneurial opportunities in the poultry meat production sector. In addition, the annual import of meat and its economic value were also examined. For this purpose, INSAE, Ministry of Agriculture and Livestock (MAEP) and FAO reports were reviewed. In addition, some data from similar articles published on this subject have been used. As a result of this review, it can be said that food products and consumption patterns are changing due to the per capita income growth and the expansion of food options. In Benin, food products and consumption patterns are changing due to the growth of income and the expansion of food choice options. Therefore, per capita meat consumption increased and reached 25.2 kg in 2013. However, according to the average of the world meat consumption in 2013 (43.22 kg / person / year) this amount is very low. In general, 21% of the meat produced in Benin consists of poultry meat. National poultry breeding does not meet the rising demand for meat. The part of local production in consumption decreased significantly from 2005 to 2013 (from 21% to 6%). 98% of the total meat imported to Benin is composed by poultry meat (chicken and turkey meat). From 2010 to 2016, the average of imported poultry meat value is $216,358 million and this situation causes loss of currency. Considering the available data, investment opportunities for poultry production in Benin should be evaluated. In addition, there are significant shortcomings in the field of food safety and the provision. The development of the needs in this sector includes entrepreneurship opportunities.

Ülkemizde mısır üretimindeki artış bir yandan sürerken, bir yandan da dünyada mısırın soyadan sonra en çok genetiği değiştirilmiş ürün olması nedeniyle tüketicinin mısır ile ilgili algısı her geçen gün daha olumsuz olmaktadır. Genetiği değiştirilmiş mısırın potansiyel olumsuz etkileri tartışılmakta iken, mısırda insan sağlığı için gözden kaçmaması gereken en büyük tehdit mikotoksinlerdir. Bu çalışmada, Türkiye’nin 24 ilinde bulunan 552 köyün 634 tarlasından toplanan mısır numuneleri GDO, aflatoksin B1, toplam aflatoksin, fumonisin B1, fumonisin B2, T-2 toksin, HT-2 toksin, zearalenon ve deoksinivalenol yönünden incelenmiştir. Tarama yapılan mısır numunelerinin hiçbirinde transgenik elemente rastlanmamıştır. Analiz edilen 634 numunenin sadece bir tanesinde Türk Gıda Kodeksi limitinin üzerinde aflatoksin B1 miktarına rastlanmış, numunelerin toplam aflatoksin değerleri Türk Gıda Kodeksi limitinin altında çıkmıştır. Paçal oluşturulan numunelerin hiçbirinde T-2 toksin, HT-2 toksin, zearalenon ve deoksinivalenol tespit edilmezken, fumonisin tespit edilen numunelerin toplam fumonisin miktarı Türk Gıda Kodeksi limitinin altında bulunmuştur. Bu sonuçlar, yerli üretim mısırların gıda güvenliği açısından uygun standartları sağladığını göstermektedir.

In this study; the human health risks of whiting meat and roes, which are frequently consumed in Turkey were evaluated in terms of minerals and heavy metals. The potential of human health risks according to consumption of whiting meats and roes were assessed by estimating of Metal Pollution Index (MPI), Estimated Weekly Intake (EWI), Target Hazard Quotient (THQ), Total Target Hazard Quotient (TTHQ) levels of heavy metals. The Cd, Hg and Pb results found in the roes were lower than the acceptable limits identified by Turkish Codex. The results showed that the investigated fish meat’s Pb levels were higher than the limit values except from in April and May. The highest Cd content was 0.22 mg.kg-1 in whiting meat in December while the lowest Cd content was 0.03 mg.kg-1 in May. The maximum value of metal pollution indices (MPI) was determined as 0.44 for whiting meat and 0.66 for roes in March. The THQ values of whiting meat and roes were lower than 1 for six months. However, the TTHQ values of whiting meat in February and March were higher than 1 indicating health risk for the consumer by consuming whiting meat.

β-thalassemia major is severe hemolytic anemia which requires repeated blood transfusion and for survival, which leading to iron overload. Serious complications due to iron over load are recognized in the thalassemia patients. objectives Vitamin D and calcium are important factors for homeostasis of calcium in this study. This study was conducted for a period of two year including from patients with β- thalassemia major from Duhok Thalassemia Centre between 2014 -2015. Thirty eighth β- thalassemia major patients and thirty eighth persons with age- matched as control group were enrolled in the study. Serum concentration of 25- hydroxy vitamin D and calcium were estimated by enzyme linked fluorescent assay and colorimetric method, respectively. In patients, the level of serum 25- hydroxy vitamin D was significantly lower 11.11±4.36 ng/mL compared with control group (14.03±5.96ng/mL). Vitamin D deficiency is observed about 94.73% in patients. The mean level of serum calcium in patients group is 7.9±0.47mg/dL and 8.98±0.77 mg/dL in control group. There was a statistically significant difference in serum calcium value between patients and control group. 44.73% of patients have hypocalcaemia. This study demonstrated a high prevalence of Vitamin D deficiency and low total serum calcium levels in thalassemia patients with a significantly lower than healthy group. Hypocalcemia and vitamin D deficiency may be results from the negative effect of the repeated blood transfusion and malnourishment.
