Skeletal abnormalities in farmed fish are one of the main problems that negatively affect the production enterprises in terms of economic, biological and animal health. Fish with skeletal deformities in hatcheries are considered as non-economic individuals and are therefore detected and removed manually from the production tanks, which is a time consuming and laborious work for the facilities. Since the formation of abnormalities in the skeletal structure of the fish during the early growth period cause reduced swimming ability or speed that prevent fish to compete during feeding. Further, since deformed fish has no market value, even the share of a small amount of feed among deformed fish will reduce the feed conversion for the market targeted individuals within the culture tank that in terms may increase the production cost per fish. Therefore, in culture conditions it is important to remove the deformed fish from the tank environment by quickly determining those fellows at the early stage of growth. The present study evaluates the effects of water velocity on swimming behavior of juvenile seabass (Dicentrarchus labrax) and provides a solution for a rapid identification -and mechanical removal of deformed fish from the culture environment by using swimming speed slowdown -and behavioral differences as an indicator of deformation.

Turkey is known as a top producer and exporter of apricots, both fresh and dried. More than half of Turkey's apricot production is provided by Malatya province. There are many pests and diseases affecting apricots in addition to climatic factors such as frost and hail. Partial shoot drying and sudden drying in apricot orchards have increased in recent years. In this study, it was aimed to determine the chemical control possibilities of Neoscytalidium dimidiatum (Penz.) Crous &Slippers, which is one of the fungal agents that cause partial branch drying and sudden drying in apricot orchards in Malatya province by in vitro studies. For this purpose, Kale 4-C isolate of N. dimidiatum collected from Malatya in a previous study was used. Mycelial growth of N. dimidiatum Kale 4-C isolate in PDA were observed in 0 (control), 0.01, 0.03, 0.1, 1, 3, 10, 30 ve 100 μg/mL concentrations of Azoxystrobin 250g/L, Trifloxystrobin %50, Tebuconazole %25, Floupyram 200 g/L+Tebuconazole 200 g/L, Cyprodinil+Fludioxonil %37.5+25, %70 Thiophanate-Methyl and 400 g/L Phosphorous acide fungicides applications. As a result of the study, Floupyram 200g/L+Tebuconazole 200g/L ve Cyprodinil+Fludioxonil %37.5+25 fungicides effectively inhibited the mycelial growth of the fungus.

Ambient storage stability is one of the major constrains amidst drudges of homemade soymilk due to absence of stabilizer there by restricting the consumption to the production areas. Homemade stabilizers and stabilization becomes the only available option. Soymilk prepared from 12 h steeped and 72 h sprouted soybeans was subdivided and each batch stabilized with 0.5%, 1%, 2% and 3% levels of orange flesh sweet potato starches (OFSPS). Functional properties of the starches and proximate, vitamins, minerals, anti-nutrient, physicochemical, and sensory properties of stabilized soymilk samples were assessed with standard analytical methods. With increase in fortification levels, there were significant improvement in ash (0.84 to 0.88%), protein (4.14 to 4.24%), fibre (0.31 to 0.39%), fat (3.75 to 4.19%), carbohydrate (4.54 to 5.55%), vitamins B1 (0.29 to 0.4 mg/100g), B2 (0.10 to 0.14 mg/100g), B3 (1.03 to 1.13 mg/100g), C (0.86 to 1.09 mg/100g) and pro-vitamin A (5.75 to 6.14 µg/100g). Also improved are calcium (26.81 to 28.55 mg/100g), potassium (31.54 to 32.95 mg/100g), magnesium (44.40 to 46.82 mg/100g), sodium (32.73 to 33.43 mg/100g), iron (2.82 to 3.71 mg/100g), saponin (0.028 to 0.035 mg/100g), tannin (0.041 to 0.048 mg/100g), flavonoid (0.031 to 0.034 mg/100g), alkaloid (0.025 to 0.034 mg/100g), phenol (0.25 to 0.34 mg/100g), viscosity (4.89 to 5.60 mg/100g) and specific gravity (1.02 to 1.04 mg/100g). There were decrease in moisture (86.39 to 84.86%), pH (5.75 to 5.45), visible coagulation time (VCT) (28 to 14 d), foam stability (0.51 to 0.00) and general acceptability (6.84 to 4.84). Functional properties of the OFSPS flour were reasonably high. Despite the anti-nutrient increase, all the soymilk samples in this study were safe for human consumption and moderately accepted at maximum stabilization level of 1%.

The aim of this investigation was to determine appropriate perennial grasses and their most suitable mixture ratios, which can be grown with alfalfa in binary mixtures. The research was conducted during 2009-2011 in Isparta (37.50 °N, 30.32 °E), located in the Western Mediterranean climate conditions. In the study, alfalfa was planted as a binary mixture with perennial ryegrass (Lolium perenne L.), orchardgrass (Dactylis glomerata L.), meadow fescue (Festuca pratensis Huds.), and smooth bromegrass (Bromus inermis Leyss.) in a randomized block design with three replications. Sowing ratios of alfalfa in the mixtures varied 20, 30, and 40%, and grass species ratios were 80, 70, and 60%. In the study, significant differences were found among the applications regarding hay yield, crude protein content, crude protein yield, NDF, ADF, land equivalent ratio (LER), and grass ratio in the hay (GR). The highest hay yield was obtained from alfalfa + orchardgrass and alfalfa + smooth bromegrass binary mixtures (25.98 and 25.78 t ha-1, respectively). Alfalfa + perennial ryegrass and alfalfa + meadow fescue mixtures gave the highest crude protein contents as 14.93 and 14.80%, respectively. The highest LER values were observed on perennial ryegrass and smooth bromegrass binary mixtures, and the highest grass ratios were determined in orchardgrass and smooth bromegrass mixtures made with alfalfa. Increasing the alfalfa sowing ratio in the mixtures positively affected all quality characteristics such as crude protein, NDF, and ADF. It was concluded that orchardgrass and smooth bromegrass binary mixtures with alfalfa produced high yield and quality hay and that the mixture should contain 40% alfalfa and 60% grass.

The purpose of the study is to examine the role and impacts of growth hormone in maximizing animal products. Growth hormones are biological stimulants that are found either naturally in the organism or synthetically manufactured. Phytoestrogens, phytoprogestrons and Phenolic compounds are hormones from plants. Drugs from of placenta and colostrums of cow`s contain progesterone, estrogene, gonadotropin, and prostaglandins hormones. Growth hormones have got popular applications in dairy, beef, feed improvement and Biopharmaceutical productions with the aim of producing valuable products: fat free meat (Porcine Somatotropin hormone in pigs), nutritionally and medicinally reach milk (Bovine Somatotropin hormone in cattle), palatable and disease and insect pest resistant forage crop production. They have got also contribution in maximizing livestock production by involving in adjusting animals’ reproductive process such as oestrus synchronization and superovulation mainly during artificial insemination and embryo transfer. Controversially, these hormones have wide impacts on human being, animal welfare, environment and etc. Contamination of ground water by hormones that are found in the animals` excreta will cause deleterious effects such as cancer, loss of fertility, and some imbalance of minerals in the water and soil.

Günümüzde insan ve çevre sağlığını tehdit eden en önemli problemlerin başında hava kirliliği gelmektedir. Hava kirliliğinin pek çok bileşeni bulunmakla birlikte, bunlar arasında ağır metaller ayrı bir öneme sahiptir. Bunun sebebi ağır metallerin bazılarının düşük konsantrasyonlarda bile toksik olmaları, canlılar için besin elementi olan birçok ağır metalin bile yüksek konsantrasyonlarda zararlı olmaları, canlı bünyesinde biyobirikme eğiliminde olmaları, doğada kolay kolay bozulmamaları ve bunlara ek olarak sanayi ve trafik kaynaklı olarak havadaki konsantrasyonlarının sürekli artmasıdır. Bundan dolayı özellikle trafiğin yoğun olduğu, sanayi faaliyetlerinin yürütüldüğü ve nüfusun yoğun olduğu alanlar gibi riskli alanlarda havadaki ağır metal konsantrasyonlarının izlenmesi büyük önem taşımaktadır. Bu çalışmada da, Samsun kent merkezinde yetiştirilen ve peyzaj çalışmalarında sıklıkla kullanılan; Tilia tomentosa, Aesculus hippocastanum, Ligustrum vulgare ve Catalpa bignoides türlerinin, trafiğin yoğun olduğu, az yoğun olduğu ve hemen hemen hiç olmadığı alanlarda yetişen bireylerinde Cr konsatrasyonlarının değişimleri belirlenmeye çalışılmıştır. Çalışma kapsamında bitkilerden yaprak, kabuk ve odun örnekleri toplanmış, kabuk ve yapraklarda ayrıca yıkama işlemi uygulaması da yapılmıştır. Çalışma sonucunda, çalışmaya konu türlerde Cr konsantrasyonlarının tür, organ ve trafik yoğunluğu bazında önemli ölçüde değiştiği belirlenmiştir.

Wheat is an important cereal product because of its nutritional value, economy, culture, and history. Einkorn (Triticum monococcum L.) assumed as the oldest wheat. Einkorn locally called “siyez” has recently become popular as a super grain with the thought of being very nutritious in Turkey. In this study, the contents of macrominerals (Na, Mg, Ca, and K) and microminerals (Cr, Cu, Fe, Mn and Zn) in twenty-one einkorn samples collected from different cultivation areas in Kastamonu were determined by using an inductively coupled plasma-optical emission spectrometry following microwave-assisted acid digestion. The results were compared with those analyzed in einkorn and other wheat types in the literature. Average concentrations of K, Ca, Mg, Na, Fe, Zn, Mn, Cr and Cu analyzed in einkorn samples were found as 3712, 1303, 656, 53, 167, 34, 29, 0,7 and 0,6 mg kg-1, respectively. The literature comparison revealed that the investigated einkorn samples were richer in terms of Ca and Fe contents compared to einkorn, emmer, spelt, buckwheat, and durum wheat samples grown in our country and different countries.
