The polyunsaturated fatty acids (PUFA) of lipids in muscle of sardine were known as unstable to oxidation. Propolis is a natural compounds produced by honey bees from substances collected from parts of plants, buds, and exudates. Nowadays, the particular attention has been attributed to propolis underlying their antioxidant properties due to the presence of the flavonoids, phenolic acids, and ethers. The impact of water and ethanolic extract of propolis at doses of 0.4 and 0.8% on fatty acid changes of vacuum packaged sardine fillets were investigated during chill storage. The main fatty acids in sardine fillets were palmitic acid (C16:0), palmitoleic acid (C16:1), myristic acid (C14:0), eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6 n3), respectively. There was no significant differences in EPA and DHA between control and treated groups during storage apart from 4 and 11th day. Initial n6/n3 ratio in sardine fillet was 0.17. Group treated with 0.4 propolis ethanolic extract comprised lower n6/n3 ratio at 4, 11 and 13th days than that of other groups. Although the effects of propolis extracts on fatty acid composition of fish were variable, application of propolis ethanolic and water extracts on fish fillets at doses of 0.8% had a positive impact due to lead a better oxidative stability of PUFA content.

The fisheries sector makes significant contributions to the economy for the animal nutritional needs of the people, industry, employment and national income. In particularly the aquaculture sector is one of the fastest growing sectors in Turkey with a growth rate of 11%. Antalya is one of the provinces with an importance in the aquaculture sector. Unfortunately, it is not possible to use this potential efficiently either as the province is also a major tourism destination. As a matter of fact, cage nets in the province have been moved to further locations due to tourism. However, there are still 78 active aquaculture facilities in Antalya, including 73 trout and 5 seabream-seabass. These businesses are performing about 2% of Turkey's aquaculture production. As of 2017, aquaculture production amount in the province was 5,693 tons/year. There are 5 fishing shelters in Antalya in 2017. These are located in Konyaalti, Alanya, Finike, Kas (Center) and Kas (Kalkan) regions. However, the number of landing points cause some confusion and problems in terms of control. For this reason, it is requested to open a Seafood Wholesaler in the province. The fisheries and aquaculture production was 6,779 tons/year in Antalya and 1680 tons in 2016, 1898 tons in 2017 and 2359 tons/year as of 2018 were exported.

In this study which was carried out during the 2015 summer season in Eskişehir, the flower, pod and seed characters attributed to yield components were investigated in 12 forage pea genotypes. They showed significant differences in terms of agronomic and morphological (flower, pod, and seed) traits. The highest fresh hay yield with 2171 kg/da and plant height with 106.6 cm were obtained from Populasyon-1. Crackerjack had lower values in some flower traits such as, whereas the higher values of pod and seed traits were obtained from cv. Rose. In addition, Population-1 included in the higher value group for standard petal width, keel petal length, calyx tube and teeth lengths, and flower length. Although cluster analysis did not reflect agronomic traits, the clustering resulted in four groups. The first group consisted of Özkaynak 1, 2, and 3 and Taşkent, Töre, and Population-2, which were the standard petal colour violet, light, and dark violet. Population-1 had both violet and white standard petal; however, it was included in the second group together with white-flowered Ulubatlı and Ürünlü according to cluster analysis. While Rose and Gölyazı were in the third group, Crackerjack was in the fourth group alone. There was a highly significant positive correlation between fresh hay yield and both standard petal width and length and flower length. Consequently, a hopeful result for summer growing in Eskişehir condition was obtained from Population-1. It was suggested that some flower characters can be used for pre-selection of yield-related traits in the evaluation of genetic diversity of pea germplasm through morphological trait.

In this study, the effects of two traditional, three reduced and a zero tillage methods applied for nine years on GEA and PMN were determined and compared. The study, initiated in 2006 as randomized block design, includes a total of 18 plots with 3 replications for 6 different soil tillage systems. In the study, six different soil tillage methods are applied, namely conventional tillage with stubbles (CT-1), conventional tillage with stubbles burned (CT-2), reduced tillage with heavy disc harrow (RT-1), reduced tillage with rototiller (RT-2), reduced tillage with heavy disc harrow (RT-3) and no tillage (NT). Winter wheat was grown as the main crop every year or corn and soybean was grown following the harvest of wheat (second crop) every other year. Differentiation of tillage systems led to a significant variation in GEA and PMN concentrations. The GEA concentration, which increased significantly with the decrease in tillage density, varied between 44.68 mg PNP kg-1 h-1 (CT-2) and 207.66 mg PNP kg-1 h-1 (STI). However, the trend determined in GEA could not be detected in PMN. Although PMN concentration was significantly higher in soils under NT, it was included in the same statistical group with RT-1 for PMN concentrations. Higher PMN concentration in no till soils can be possibly related to the non-disturbance of soil structure. The results of study revealed that reduced and no tillage systems are extremely necessary to increase the quality of soils in the region.

In this article, the definition, the structures, the types, the sources of production, the application areas, the microorganisms they act on and the mechanism of action of antimicrobial peptides and information about the studies related to their use in poultry nutrition will be given.

The electronic tongue is defined as the device, consisting of a series of sensors, used to characterize the taste of complex liquid or converted into liquid form samples. This device can be used in many fields of application; in medicine, chemistry, environment, and food industry. In the food industry. usually, the electronic tongue is used to control the freshness, the maturity, and the non-deterioration of fruits, vegetables, meats, beverages, and dairy products. Commonly, trained panelists participate in taste and sensory analysis. However, the electronic tongue is preferred due to the encountered disadvantages, where the taste perception is subjective and moreover, varies from an individual to another. In the present review, the basic structure of electronic tongues with different systems, working principles, food application areas, advantages, and disadvantages are discussed.

Nowadays, whitening of stained teeth has become the most popular topic in aesthetic and cosmetic dentistry. Because of the side effects of materials that were used for bleaching, in this study the effects of some plants which were used in Anatolian folk medicine on the treatment of tooth staining were examined. In this study, upper central incisors which were extracted for periodontal reasons were used. The colour values of numbered teeth were obtained and the teeth were immersed into three different essential oils of medicinal plants (Mentha piperita, Ocimum basilicum, Rosmarinus officinalis, Salvia officinalis) for different time periods (1 day, 1 week, 1 month). At the end of the immersion periods, colour measurements of all samples were made and the colour changes were analysed. Obtained data were statistically analysed by using ANOVA and Duncan test. As a result of the variance analysis, plant species and the duration of immersion was found to be statistically significant. Within the limits of this study, we can indicate that tested medicinal plants has a whitening effect by resulting significant change in tooth colour.

The aim of study was to determine the phenological characteristics of seed materials collected from mungbean cultivation provinces in our country. This experiment was conducted at the Department of Field Crops, Faculty of Agriculture, Isparta University of Applied Sciences (ISUBU). In study, 91 materials were collected in 2015 and seed reproduction and pre-observations were made this year. According to preliminary observation results, 50 mung bean genotypes selected together with 4 registered varieties were taken into field trials in 2017 and 2018. The experiments were conducted at an Augmented Design with five replications. As phenological properties of experiment were germination time, flowering time, podding time and vegetation time. As a result of the study, it was found that there are genotypes with earlier characteristics than registered varieties. 27 S 08 genotype was the earliest among genotypes. This genotype is thought to be promising in the future.

This study was conducted to compare the internal and external quality characteristics of the eggs of Atak-S laying hybrids kept in enriched cage and free-range rearing systems. In the study; 400 Atak-S hybrids, 31 weeks of age were fed for 6 weeks of experimental period. Throughout the experiment, with weekly intervals, 15 eggs of each group were collected from the laying hens kept in both systems for determination of the quality of the exterior (egg shape index and egg shell thickness) and interior (albumen and yolk width, height, yolk height and yolk colour). At the end of the experiment, there were statistically significant differences between groups for Haugh unit (wk. 2), albumen index (wk. 6), egg shell rate (wk. 1, 2, 3), egg shell thickness (wk. 6), yolk colour for L (wk. 3) and for a (wk. 1, 3). However, there were no significant differences between groups for other weeks and mean values, egg weight, shape index and yolk index.
