2014
Aziz Şahin | Arda Yıldırım
Mastitis is an important disease which causes economic losses in the water buffalo breeding. According to severity, duration and primary, mastitis is generally classified as clinical and subclinical. Because of contamination from other animals in the herd, subclinical mastitis is a important dairy herd problem. However, clinical mastitis is a clinical case created by deformation of udder gland and decreasing milk yield. Staphylococcus aureus, Escherichia coli, Streptococcus agalactia and Streptococcus dysgalactia are in clinical mastitis, but Escherichia coli, Staphylococcus aureus, Pseudomonas, Streptococcus agalactia and Streptococcus dysgalactia are the most common isolated microorganisms in subclinical mastitis. Due to mastitis caused by these microorganisms in Water Buffalo, abnormality in the structure of milk are observed, and it causes economic losses to farmers from reduced production. Therefore, the detection of effective factors on mastitis and taking of the necessary precautions are very important. In this review, mastitis case in water Buffalo and its effects were discussed.

Berken Çimen | Meral İncesu | Turgut Yeşiloğlu | Bilge Yılmaz
Pomelo [Citrus grandis (L.) Osbeck] has the largest fruit size among citrus species. There are several cultivars for pomelo species which is sensitive to low temperatures thus its cultivation is possible in relatively preserved areas in subtropical regions. The interest to pomelo production has increased due to several reasons such as, its has a little or no bitterness in fruit flesh conversaly to grapefruit, avaibility of pigmented varieties, high concentration of vitamin C, total phenolics and carotenoids in fruit flesh, as well as its efficiency in destroying free radicals such as superoxide anion and hydrogen peroxide. Several pomelo varieties have been introduced to Turkey and adaptation studies have been established. In the present study, Reinking, Pomelo WN, Kao Panne and Citrus hassaku which is a spontaneous hybrid between pomelo and mandarin were investigated in terms of fruit yield and pomological characteristics. In addition, Henderson grapefruit was included in this study in order to obtain a comparasion between pomelo and grapefruit. A large variation was observed in fruit yield of cultivars established in 2011 and 2012. In 2011, the highest yield was determined in Henderson whereas it was obtained from Citrus hassaku in 2012. Pomelo varieties yielded between 5-60 kg fruit per tree and 8.6-50 kg fruit per tree in 2011 and 2012, respectively. In terms of pomological traits, Citrus hassaku had the highest fruit weight; Pink, Kao Panne and Reinking pomelos had the highest peel thickness and Pomelo WN yielded the highest TSS/TA ratio.

Fire blight disease caused by Erwinia amylovora is a destructive bacterial pathogen mainly on pears, apples and quinces from Rosaceae family. In this study, it was aimed determination of total protein amounts in different apple cultivars (Braeburn, Fuji, Gala and Golden), pear cultivars (Santa Maria and Williams) and quince cultivars (Eşme and Ekmek) in the infections of two virulent E. amylovora strains (Ea234-1 and Ea240-3) according as the time. It was taken leaf samples after leaf inoculation with E. amylovora (108 CFU ml-1) at 24th, 36th and 72nd hours. For verification of the infections, re-isolations were made from bacteria inoculated plants and the agent was identified as E. amylovora by biochemical, physiological and molecular tests. In determining the amounts of total protein and in the SDS-PAGE analyses were used Bradford and Laemmli methods, respectively, and absorbance values of protein extracts derived from the leaf samples taken, were obtained at 595 nm wavelength. According to the findings obtained; after infection of E. amylovora in the apple varieties comparing to controls, total protein concentrations at 24th hours increased and a decrease in the amount of 36th to 72nd hours and Braeburn has the highest protein content was determined. In the pear varieties, while total protein concentrations at 24th and 36th hours increased, a decrease in the amount of 72nd hour, and Santa Maria variety has the highest protein content was detected. In the quince varieties, total protein concentrations at 72th hour increased and Eşme variety has the highest protein content was identified. As a result of SDS-PAGE analysis, protein fractions which have different molecular weights were obtained. The protein bands were defined approximately 55-70 kDa and 35-55 kDa molecule weight on apple and quince varieties, respectively and also approx. 55-70 kDa in pear varieties.

Mehfuz Hasan | Mohammad Sharif Raihan
Genetic polymorphism and relationships among 30 commercial varieties of Bangladeshi aromatic rice (Oryza sativa L.) were established using random amplified polymorphic DNA (RAPD) primers. Out of fifty 10-mer RAPD primers screened initially, four were chosen and used in a comparative analysis of different varieties of indigenous Bangladeshi aromatic rice. Of the 33 total RAPD fragments amplified, 7 (21.21%) were found to be shared by individuals of all eight varieties. The remaining 26 fragments were found to be polymorphic (78.79%). Pair-wise estimates of similarity ranged from 0.101 to 0.911. Highest genetic diversity was determined between Radhunipagol and Dubsail varieties (0.911). The amount of genetic diversity within aromatic rice germplasm was quite high as determined by the genetic similarity coefficients between varieties. Genetic similarities obtained from RAPD data were also used to create a cluster diagram. Cluster analysis using an un-weighted pair-group method with arithmetic averages (UPGMA) was used to group the varieties and the 30 aromatic rice varieties were grouped into 6 clusters where cluster I includes the maximum number of varieties (9). Cluster VI includes minimum number of varieties (2). This Study offered a rapid and reliable method for the estimation of variability between different varieties which could be utilized by the breeders for further improvement of the local aromatic rice varieties.

Microbial population of soil and its structure is affected with chemical and biological changes such as plant-root secretions. Upper layer of the soil is exposed to mixture of stems, fruiting bodies and leaves of trees. Seven trees growing at same area were chosen. Their upper layers of the soil were collected from depth 5-10 cm as samples in spring and autumn. Their microbial populations were investigated in order to determine in terms of climate changes. In order to determine the number of the total microorganisms, gram-negative bacteria and spore-forming bacteria (cfu/g) were used by the serial dilution techniques. As a result, the highest numbers of microorganisms from the soil of the apple tree were determined as the total microbial count in the autumn, although the lowest number of microorganisms was obtained from the soil of the pine tree. However, the number of the gram-negative bacteria was the highest in the soil of linden tree, although the number of gram negative bacteria was the lowest in the soil of apricot, mulberry and apple trees. For spore - forming bacterium, the highest number from the mulberry soil and the lowest number from the linden tree have been obtained. In the spring, the highest numbers of microorganisms from the soil of the apple tree were obtained as the total microbial count, although the lowest number of microorganisms was obtained from the soil of the apricot tree. For the number of the gram-negative bacteria was the highest in the soil of walnut tree, although the number of gram negative bacteria was the lowest in the soil of apricot trees. However spore - forming bacterium, the highest number from the soil of the poplar tree and the lowest number from the mulberry tree have been obtained. In general, the rich diversity of the microbial population was shown morphologically in autumn.

Sayed Mohammad Naim Khalid
Food labels describe the content of a food and are intended to guide the consumer in food selection. The nutrition information provided must be in consistency with legal requirements and dietary recommendations. Selection of the specific nutrients or food components to be listed should further take into account label space, the analytical feasibility of measuring the particular nutritional component within the food matrix, and the relative costs of such analyses. Information provided on labels should be truthful and not mislead consumers. At the same time, labeling regulations should provide incentives to manufacturers to develop products that promote public health and assist consumers in following dietary recommendations. In some countries some segments of the population benefit from information about the composition of foods. In such cases, countries should consider the need to provide for appropriate labeling and its presentation relative to existing regulations. Different approaches and legal requirements have been established. These create difficulties in developing and harmonizing labels, which have broad international applications. For these reasons, the Codex Guidelines on food labeling play an important role to provide guidance to member countries when they want to develop or update their national regulations and to encourage harmonization of national with international standards. These Guidelines are based on the principle that no food should be described or presented in a manner that is false, misleading or deceptive. Exchange of information at the regional and sub-regional level is important, as each country can learn from the experience of others and regional co-ordination and co-operation can be developed.

Mustafa Boga
Nowadays, meeting adequately nutrient requirements of animal is a major problem due to cost of feed. This situation results in the feed manufacturers to search alternative feed source in order to provide more economical feeding in animal nutrition. In Turkey known as a paradise of olive, a number of substances were discharged to the environment during olive processing. After pressing of olive, the olive remains such as olive cake and black water cause off-odour, groundwater pollution, visual pollution and formation of a fly in environment. Among these by-products, olive cake has been extensively used as fuel. However, olive cake and black water can be used as alternative animal feed due to their high nutrient contents. In this review, the importance and use of the olive cake and black water in animal nutrition will be discussed.

Murat Türkeş
This paper focuses mainly on both impacts of the climate change on agriculture and food security, and multidisciplinary scientific assessment and recommendations for sustainable agro ecological solutions including traditional knowledge responding to these impacts. The climate change will very likely affect four key dimensions of the food security including availability, accessibility, utilization and sustainability of the food, due to close linkage between food and water security and climate change. In one of the most comprehensive model studies simulating impacts of global climate change on agriculture to date, it was estimated that by 2080, in a business-as-usual scenario, climate change will reduce the potential output of global agriculture by more than 3.2 per cent. Furthermore, developing countries will suffer the most with a potential 9.1 per cent decline in agricultural output, for example with a considerable decrease of 16.6 per cent in Africa. Some comprehensive studies pointed out also that all regions may experience significant decreases in crop yields as well as significant increases, depending on emission scenarios and the assumptions on effectiveness of carbon dioxide (CO2) fertilization. One of the tools that would ensure the food security by making use of local sources and traditional knowledge is agroecology. Agroecology would contribute to mitigation of the anthropogenic climate change and cooling down the Earth’s increasing surface and lower atmospheric air temperatures, because it is mainly labour-intensive and requires little uses of fossil fuels, energy and artificial fertilisers. It is also necessary to understand the ecological mechanisms underlying sustainability of traditional farming systems, and to translate them into ecological principles that make locally available and appropriate approaches and techniques applicable to a large number of farmers.
