Heracleum platytaenium Boiss. has been used in traditional medicine. Antioxidant effect of essential oil as well as extracts of H. platytaenium was investigated. The essential oil was acquired by hydro distillation using a Clevenger type apparatus and GC-MS was used to analyze the essential oil compounds. Antioxidant capacity including ABTS+•, DPPH• scavenging and reducing power activity tests were carried out for essential oil and extracts. Moreover, total phenolic and total flavonoid contents were investigated. n-Octyl acetate (36.5%), apiole (24.9%), and elemicin (20.8%) were the chief products of essential oil. The essential oil and extracts exhibited from weak to moderate activity. The total phenol varied from 19.01 to 130.99 mg GAE/g extract and total flavonoid was fluctuated from 2.0 to 118.4 mg QE/g extract. The most DPPH• scavenging effect was observed in EtOAc extract (IC50 = 24.09 mg ml –1). The ABTS•+ scavenging effect of EtOAc extract was better than synthetic antioxidants BHA, BHT and Trolox.

Anatolia has a wide range of variety and species of grape due to its location is within the native lands of the grape. Turkey is one of the world’s major winegrowing centre because it has an important potential in terms of vineyards area and grape production. Today, people have turned to organic farming due to unbalanced population movements, depletion of natural resources, climate change, conscious consumption and food security. Organic agriculture is an agricultural system that aims to evaluate the future of human and ecosystem as an indivisible whole with healthy plant and animal production. Grape is in the first place in terms of trade among horticultural plants worldwide. In this context, grape is one of the most important of the 197 organic crops grown in our country. The large proportion of organic grapes produced in our country is dried and the organic dried grape is exported abroad. Therefore, the demands of the foreign market are great importance. With this research, the recent situation of organic viticulture in our country has been reviewed and suggestions have been made for improvements.

In this study, copper toxicity, was investigated after the addition of zeolite to the diet of common carps (Cyprinus carpio). The experiment included four groups with three replicates each. The 4 group feeds were [CuSO4; CuSO4 + Zeolite; Zeolite, and the control without CuSO4 or Zeolite with three replicates each. Fishes were kept in 80 L glass aquariums with 10 fishes with a mean weight of 60.6 ± 0.2 g. At the end of each period, a necropsy was performed on fishes from each treatment, and gross clinical signs were recorded. We found significant changes in the blood parameters of the common carps with or without different levels of zeolite and copper. Changes in cholesterol (CHOL), triglyceride (TG), low density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), calcium (Ca2+), phosphorus (P+), sodium (Na+), potassium (K+), chloride (Cl-), magnesium (Mg2+), and ferrous (Fe+2) were also significant. Our results suggest that zeolite can be used in fish feeds at a rate of 40 mg/l to mitigate the toxic effects of copper.

Bu çalışmada, ticari faj preparatının çiğ sütten yapılmış beyaz peynirde Salmonella kontrolü üzerine etkisi araştırılmıştır. Bu amaçla Salmonella faj preparatı kullanılmıştır. Beyaz peynir üretimi 4 grupta yapılmıştır. Bunlar; 1-kontrol grubu (çiğ süt), 2-çiğ süt+patojen (Salmonella Typhi, %0,05), 3- çiğ süt+faj ilave edilen (%0,1), 4-patojen (%0,05) + faj (%0,1) grubu olarak belirlenmiştir. Beyaz peynir örneklerinde olgunlaşmanın 0., 30., 60. ve 90. günlerinde fizikokimyasal ve mikrobiyolojik analizleri yapılmıştır. Yapılan fiziko-kimyasal analizler; pH, titrasyon asitliği (ºSH), kuru madde, kuru maddede yağ, tuz ve kuru maddede tuz tayinidir. Mikrobiyolojik analizler; toplam aerobik mezofil bakteri, laktik asit bakterileri, Stafilokok spp., koliform grubu bakteri, Salmonella spp. ile faj ilave edilen peynir örneklerinde faj titresi analizidir. Ayrıca faj ilave edilen örneklerin sütlerinde ve peynir altı sularında faj titresi durumu incelenmiştir. Peynir örneklerinde, faj uygulamasının veya söz konusu bir patojen bulaşısının örnekler arasında fiziko-kimyasal ile genel mikrobiyolojik özellikleri bakımından farklılık gösterici etkisinin olmadığı elde edilen veriler sonucunda belirlenmiştir. Bu değerler tüm peynir gruplarında sadece süreye göre değişkenlik göstermiştir. Salmonella spp. sayısında ise 90. günde 2 ve 4 numaralı grup arasındaki fark kontrol grubuna göre kıyaslandığında istatistiksel olarak önemli bulunmuştur. Bunun haricinde Salmonella spp. sayıları gruplar arasında farklı bulunmamış, sadece olgunlaşmanın doğal süreci olarak günlere göre azalış göstermiştir. Bu çalışma sonucunda, çiğ sütten yapılan beyaz peynirlerde bakteriyofaj ilavesinin peynirin fiziko-kimyasal ve mikrobiyolojik özelliklerine etki etmediği ve faj etkisi ile patojen bakteri sayısında önemli bir fark olmadığı tespit edilmiştir.

In the drier farming regions of the world, where crop production is constrained by short growing period, unpredictable and short rainfall with sporadic run-off, in-situ rainwater harvesting is vital for successful crop production. In connection to this, a study was conducted in Fedis district of Oromia region during the main rainy seasons of 2015 and 2016 to evaluate the effects of in-situ rainwater harvesting techniques (Ridge Furrow (RF), Contour Ridge (CR), and Tied Ridge (TR)) on soil moisture conservation and grain yield of maize. A spilt-plot design was used and soil moisture content was measured at three growth stages of the crop to a depth of 60 cm with 20 cm interval. The results showed that water harvesting techniques significantly increased moisture conservation compared to the control, which was flat bed preparation. Averaged over the three stages, the TR, CR and RF treatments increased soil moisture storage by 134.59, 128.57, and 121.87%, respectively, compared to the control. The study also revealed that the in-situ rainwater harvesting techniques, due to the improved soil moisture storage, significantly affected grain yield of the maize. Averaged over the two years, the TR, CR, and FR increased the grain yield 143.14, 131.47 and 121.16%, respectively, over the control treatment. Therefore, in drier environments, such as Fedis, in-situ rainwater harvesting techniques can be recommended for better moisture conservation and subsequent improvement in crop production.

Endemism is an important criterion for identification of floristic regions and determination of floristic properties of these regions. Turkey is one of the world’s major countries in terms of endemism over 3.000 endemic plant species. This study was carried out in order to determine the floristic composition and endemic plant species on the serpentine and marble (metamorphic rocks) parent material in semi-arid garssland in Çankırı-Eldivan. For this reason plant samples were collected in different growing season in 2014 (month of between April- September), approximately 4ha (Marble, 3.88 ha; Serpentine, 0.08 ha) area in Çankırı-Eldivan. Study area is located A4 square according to the grid system of P.H. Davis (1965-1988) and Irano-Turanian region in phytogeographic respect. As a result of the plant sampling carried out in the area; 16 families, 27 genera, 31 species determined in serpentine parent material. Among of these plants 9 of them are endemic plant. Endemism rate of the serpentine area is 29%. In addition, 20 families, 58 genera, 72 species of plants have been identified in marble parent material and 14 plant taxa of these species endemic. Endemism ratio is 19%. Results of this study showed that parent material effects of plant diversity and endemism ratio.

The impacts of egg weight (EW), egg shell temperature (EST), egg position in the incubator (EP) and incubator ventilation program (IVP) on embryonic mortality (EM) and hatchability of fertile eggs (HFE) of broiler breeders were investigated in this study. EW was determined total 1920 hatching eggs which were obtained from middle aged (31 weeks) Ross 308 broiler breeders. These eggs were classified according to weight as heavy (65.52±0.08g), medium (61.47±0.04g) and light (57.56±0.08g) then were randomly set in trolleys of four identical incubators sorted as near the heather side – door side, humidifier side – opposite side and top – middle – bottom. In two incubators 37.78°C (100.0°F) EST and 38.06°C (100.5°F) EST were provided in the other two. Similarly, two machines were operated on classic IVP system and the other two were operated on new IVP system organised specially for this project during first 10 days of incubation. At the end of the hatching period, data including EM and HFE data were examined in eggs with different EST, EW and EP. It was found that EW and EST were affected to EM and HFE. Lower last stage + pipped but unhatched embryo rates and accordingly higher HFE were determined in eggs with 37.78°C (100.0°F) EST and light. However, differences between IVP and EP data were not significant.

The aim of this review paper is to explore the available information from research findings on the use of Turmeric (Curcuma longa) as a reliable phytogenic antibiotic for poultry production in the tropics especially in Nigeria and other countries. A wide range of phytogenic additives has found a growing interest in fortification of poultry diets. Supplementation of natural alternatives to antibiotic growth promoters in order to maintain both birds’ performance and health in the tropics will be a welcome development. Turmeric has reportedly been widely supplemented in poultry diets as natural alternative antibiotics in several studies with outstanding performances. The nutritional, medicinal, haematological and phyto-toxicological effects of turmeric were reviewed in this paper. Hence, turmeric supplementation at recommended inclusion rate in poultry feeds without posing any deleterious effects to the birds’ performances as well as the consumers of the products, and ultimately, leading to better profitability on the part of the farmers, will be a nutritional breakthrough for the farmers in the tropics.
