Ülkemiz coğrafi konumu ve iklim özellikleri bakımından zengin bir bitki örtüsüne sahiptir. Arılar ise biyolojik çeşitliliğin devamında çok önemli bir rol oynamaktadır. Bu nedenle, hem biyoçeşitliğin devamı hem de arıların kaliteli bir üretim gerçekleştirebilmeleri için çeşitli bitkisel ürünler ile ilgili araştırmalar yapılmaktadır. Arı otu (Phacelia tanacetifolia Bentham.) yetiştirildiği bölgeye bağlı olarak, arıların nektar üretimine yapmış olduğu katkı, süs bitkisi olarak kullanımı, hayvansal üretimde alternatif yem kaynağı olarak değerlendirilmesi ve örtü bitkisi olarak kullanımı ile toprak-su erozyonunu önlemesi gibi pek çok alandan değerlendirilen kıymetli bir bitkidir. Bu çalışmada, arı otunun genel özellikleri, önemi ve ülkemizde arı otu bitkisine dair yapılmış olan bazı çalışmalar bir araya getirilerek, derlenmiştir.

In this study, we investigated the effect of SNP haplotypes on insulin-like growth factor gene (IGF-1) related with weights of body, back, chest, leg and wing in the fifteen generation selected Japanese quail (C. coturnix japonica) lines according to the 5th week live weight. 8 SNP haplotypes were identified in the 167-bp DNA sequence of the IGF-1 gene coding region identified in a total of 108 individuals from three quail lines (control, high body weight: HBW and low body weight: LBW). ANOM (Analysis of Means of Analysis) was performed to determine the relationships between carcass components with SNP haplotypes and to compare quail genotypes. There were significant differences between the quail lines in terms of SNP haplotypes. As a result, it was determined that fifteen-generation selection in Japanese quails resulted in differences in insulin-like growth factor-1 gene and these differences were reflected in carcass components.

Poor soil fertility is important constraints that limited crop production in Ethiopia. The Masha district was highly prone to phosphorus fixation with ions like Aluminum ion since soil of the area is prone to acidity. This experiment was therefore conducted to investigate the effect of of phosphorus fertilizer with agricultural lime, coffee husk ash and coffee husk charcoal on yield of faba bean and agronomic efficiency of the fertilizer on acidic soils of Masha district. Field experiment involving two rates of phosphorus (23 and 46 kg P2O5/ha) and the three soil amendments was in randomized complete block design with three replication. The result indicated that significantly high grain yield was obtained from integrated application of 46 kg P2O5/ha with the agricultural lime, coffee husk ash and coffee husk charcoal with the observed values of 2265, 1953 and 1943 kg/ha, respectively. Agronomic efficiency significantly great values were obtained from treated with the agricultural lime+23 kg P2O5/ha, agricultural lime+46 kg P2O5/ha, coffee husk ash+23 kg P2O5/ha and coffee husk charcoal+23 kg P2O5/ha with the observed values of 14.86, 14.60 and 10.07, respectively. It can be concluded that 46 kg P2O5 with 2.5 ton agricultural lime, 7.5 ton coffee husk ash or 7.5 ton coffee husk charcoal per hectare on acid soils for high yield and yield components on faba bean at Masha district. When 23 kg P2O5/ha was integrated with the soil amendments, relatively high agronomic efficiency was observed.

The aim of this study is to understand Turkish consumers’ perception of functional dairy products in three different categories, namely milk, yogurt, and cream cheese, as well as their willingness to buy products with health claims. In this study, 50 untrained participants from the city of İstanbul, Turkey, were enrolled to evaluate three types of milk (calcium & vitamin fortified, soy, and whole), three types of yogurt (probiotic, strawberry flavoured probiotic, and plain) and four types of cream cheese (calcium, phosphate & vitamin fortified, reduced fat, light, and regular) using free listing testing and check-all-that-apply (CATA) questions together with Yes/No questions. Twenty-five participants were recruited from Yeditepe University’s Food Engineering Department and 25 participants from public places to form two clusters. In the free listing analysis, the number of frequent terms related to health dramatically decreased after the tasting session for all products, whereas sensory related terms became more important. CATA analysis showed that consumers look for different product properties in different dairy categories. The findings of both analyses showed that, regardless of their education and awareness, consumers still are not willing to compromise on the taste of dairy foods independent of how healthy the product might be. Their preference of functional dairy products was only 22%, 26% and 14% for fortified milk, probiotic yogurt, and fortified cream cheese, respectively. Moreover, only 30% of the participants were found to believe the health claims on the package, which is another obstacle the functional food industry has to face.

Main aim of this study was to determine the effects of different salt contents (75 mM, 150 mM and 225 mM NaCl), heavy metal (0.2 mg/L FeCl3, NiCl2, ZnCl2), lime (2 mg/L CaCO3), drought (50%) and pollution (0.2 mg/L dust of factories) on photosynthetic pigments, malondialdehyde (MDA), hydrogen peroxide (H2O2) levels, the ascorbate peroxidase (APX), catalase (CAT), guaiacol peroxidase (GPOX) and superoxide dismutase (SOD) in Siyez wheat (Triticum monococcum L.). All experiments were carried out under laboratory conditions with 16 hour-day and 8 hour-night photoperiod in an incubator at 23 ± 1°C. Results showed that mean chlorophyll-a concentration was highest in the siyez seedlings treated with the pollution, while both mean chlorophyll-b and total chlorophyll concentrations were highest with 75 mM salt application. Mean total carotenoid was, however, highest with the drought treatment and mean relative water content was highest with NiCl2 application. Mean MDA and H2O2 contents were found to be highest in the siyez seedlings treated with 225 mM salt, whereas they were lowest with NiCl2 treatment. Mean proline content was highest with the NiCl2 treatment compared to the lowest concentration in the control siyez seedlings (82 µmol/g). Mean APX, CAT and GPOX activities were noted to be highest in the siyez seedlings treated with NiCl2. In general, the siyez seedlings showed high tolerance to the pollution, NiCl2 and drought with having highest photosynthetic pigments, proline, protein content and enzymes activities. Among all treatments, 225 mM NaCl and CaCO3 negatively influenced chemical compounds of the siyez seedling. When all data are taken into consideration, it can be said that higher photosynthetic pigments, proline contents, antioxidant enzymes activities and lower MDA and H2O2 levels play an important role in the resistance of siyez seedlings against abiotic stress conditions.

In this study, it is aimed to establish quality critical points in order to determine the quality of feeds prepared in compound feed factories before production. For this purpose, quality control points should be established and continuously monitored in compound feed production. With our study, the quality of the raw materials we use in the production of compound feed (feed nutrient contents), and then determined the important technological changes in feed mill; control points were established in mill, mixer, molasses mixer, conditioning, pellet press inlet, pellet press outlet, cooler and packaging sections. Four different mixed feeds (quail, laying hens, dairy cow, beef cattle feed) were sampled from these regions. The study was carried out in a commercial feed factory. Firstly, rations were prepared with the formulation program on the computer of these compound feeds. Then, samples were taken from the determined points and nutrient contents (dry matter, crude protein, crude oil, crude cellulose, crude ash, starch, sugar, metabolic energy value) were compared with both chemical and NIRS method. According to the data obtained; In the samples taken under the mill, both chemical and NIRS methods were used and the results did not reflect the formulation values. According to the findings of the research, the results obtained from the samples taken from the sub-mixer bunker showed close values from the formulation values of the mixed feeds and it was concluded that it may be the most appropriate quality critical point.

Particularly in the fruit juice industry, the remaining peels and pulp parts are not available for human consumption after the juices are used. It is possible to evaluate these wastes by adding them to poultry feeds. A number of studies have been conducted by researchers on the nutritional value of many fruit wastes and on the performance of poultry. Natural antioxidant content has been reported to have a positive effect on growth, microbial and immunological parameters when high fruit peels are used as feed additive in poultry feeding.

In this study, total phenolic compounds which possess health-promoting effects and provide basic nutrition were aimed to determine the alterations in different grapevine leaves. Total phenolic content was determined using Folin-Ciocalteu colorimetric method by using a spectrophotometer. At the result of the study, it was determined that contents of total phenolic in leaves collected from different grape cultivars were varied to cultivars and grape leaves had high phenolic compounds as berries. Therefore the grape leaves especially wine grapes such as Narince, Boğazkere ve Kalecik Karası may be used as an easily accessible source of natural antioxidants and food supplement at pharmaceutical and food industry.

In this study, the effects of Artemia sp. nauplii and micro capsulated feed on growth performance and survival rate of guppy (Poecilia reticulata) and goldfish (Carassius auratus) larvae were compared at the end of three weeks of rearing period. Length of goldfish larvae (4.82 mm) fed Artemia sp. (from 4 to 12/mL/day) were between 7.97 and 9.76 mm at the end of the trial while these values were between 6.80 and 7.21 mm for those fed microencapsulated feed (from 10 to 30 mg/L/day). On the other hand length of guppy larvae fed Artemia sp. (from 5 to 25/mL/day) were between 13.02 and 17.00 mm, whereas these values were remained between 11.98 and 12.38 mm for those fed microencapsulated feed (from 10 to 40 mg/L/day). A similar result was also observed in survival rates. Survival rate of goldfish larvae fed Artemia sp. were 88.91-97.61% in while those fed microencapsulated feed were 6.19-87.14%. On the other hand survival rate of guppy larvae fed Artemia sp. were 99.17-100.00% whereas those fed microencapsulated feed were 57.50-87.50%. Eventually, microencapsulated feed was not as successful as Artemia sp. on the growth and survival rate of larvae of both species.

Amblyseius swirskii Athias-Henriot (Acari:Phytoseiidae) and Euseius scutalis Athias-Henriot (Acari: Phytoseiidae) are important predatory mites for citrus orchards in Turkey. The side effects of insecticides on these predatory mites have been rarely studied. In this study was investigated to the effect of tau-fluvalinate on A. swirskii and E. scutalis. The studies have conducted both laboratory and field. Field studies were carried out detecting of the side effects of tau-fluvalinate on the mixed stages of A.swirskii. and E scutalis. at Seyhan and Kozan districts in Adana, while laboratory studies were evaluated the side effects of tau-fluvalinate on the nymph stages of A. swirskii The studies were carried out following the standard guidelines which were adopted and issued by the IOBC-WPRS Working group ‘Pesticedes and Benefical Organism’. In the field studies, the effects of the pesticides were calculated according to the Henderson-Tilton formula. As a result of study, tau-fluvalinate was determined as toxic on predatory mites in the laboratory studies. Side effects of abamectin, one of the standard toxic acaricides, on predatory mites were found to be “T” (Toxic) according to IOBC class value. Side effects of tau-fluvalinate were found to be ’M’’ (Moderately Harmful) on 7th days while were detected to be “N” (Harmless) on 28th days according to IOBC class value in field condition. The fields studies at Kozan and Seyhan districts showed similar results.
