2015
Hakan Adanacıoğlu
Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is important in terms of the success of the initiatives. It's also essential to bring to the fore the various themes, such as regional delicacies, safe production methods, human and environmental health, regionalism, regional artisanship, and biodiversity to cultivate a successful marketing strategy in promotional activities of sustainable agricultural marketing initiatives.

Şahin Çadırcı | Gonca Özmen Özbakır | Ayfer Bozkurt Kiraz
An experiment was conducted with laying hens to determine the effects of feeding excesses of methionine in a practical layer diet. One hundred and thirty two laying hens at 61 weeks of age were used for the experiment. Two body weight groups (light and heavy) and three levels of mehionine were assigned to six groups of laying hen in a 2x3 factorial design. The diets were a 16.5% crude protein corn and soybean meal positive control diet (0.33% methionine), and this diet fortified with 1.00% additional DL-Methionine or 1.50% additional DL-Methionine. The diets were fed ad libitum to the hens for 10 consecutive weeks of production. For the total production period, body weight gain, hen-day egg production, egg weight, egg mass, daily feed intake and feed conversion ratio were not significantly different among any of the treatments in the two body weight groups (P>0.05). The study indicated that considerable tolerance exists in laying hens for individual excesses of the DL-Methionine commonly used as supplement in poultry diets.

Neslihan Zahide Öztürk
Bu derleme, bitkilerin kuraklık stresine karşı gösterdikleri kompleks fizyolojik ve metabolik tepki mekanizmaları hakkında bilinenleri özetlemek, en etkin yaklaşımları vurgulamak ve tarımsal anlamda önemi olan bitkilerin kuraklık toleransını arttırmak amaçlı çalışmalar için kullanılabilecek olan yeni yaklaşımları değerlendirmek amacını taşımaktadır. Kuraklık, tarımsal üretimde ciddi verim kayıplarına neden olan etmenlerin başında gelmektedir. Küresel ısınmaya bağlı olarak beklenen şiddetli kuraklık olayları, tarımsal anlamda kullanılan bitkilerin kuraklık toleranslarının arttırılması yolunda ciddi adımların acil olarak atılmasının gerekliliğini bir kez daha gözler önüne koymaktadır. Hareket edemeyen canlılar olan bitkiler, kuraklık, sıcaklık, tuzluluk ve aşırı yağış gibi abiyotik stres koşullarına büyüme ve gelişmeleri en az zarar görecek şekilde fizyolojik ve metabolik değişikliklerle tepki vermektedirler. Ancak, abiyotik stres koşullarında meydana gelen bu değişiklikler, karmaşıklıklarından dolayı uzun yıllardır üzerinde çalışılıyor olmasına rağmen halen tam olarak anlaşılamamıştır. Bu da, bitki kuraklık stres tepkisini anlamak ve tarımsal anlamda önemi olan bitkilerin stres toleransını arttırmak amaçlı çalışmalarda yeni yaklaşımlar kullanılmasını gerektirmektedir. Karşılaştırmalı genomik ve tranksriptomik çalışmaların yapılması, bitki kuraklık stres tepkisinde miRNA’ların oynadıkları rollerin anlaşılması, toleransları daha yüksek olan yabani genotiplerin mekanizmalarının aydınlatılması ve bitki stres adaptasyonunda epigenetiğin rolünün ortaya konulması öncelikler arasında yer almaktadır. Bu bilgilerin klasik ıslah çalışmalarıyla entegrasyonu, doğada gerçekleşen çoklu abiyotik stres koşullarına dayanıklı bitkilerin geliştirilebilmesi için en önemli aşamadır.

Hacer Tüfekci | Mustafa Olfaz
This study was conducted by using a survey made at 80 enterprises from 63 villages with the aim of determining situations, problems and solution proposals related to the sheep and goat farms in Kastamonu province. The average age of the farmers was 49.3 years. The farmers were 8.75% of primary school graduates, 68.75% of secondary school and also 22.6% of illiterate. The enterprises have raised animals as 31.75% of state + own land and 68.75%’ of private + leased land. Also they are kept the rate of 70% Hair goat, 30% Angora goat and 55% Merino sheep, 42.5% Akkaraman sheep, and 16.25% Turkmen genotype, 7.5% Sakız sheep and 6.25% of Kıvırcık Sheep. The average flock sizes goat and sheep enterprises were 77.3 head goats and 71.7 heads sheep, respectively. Sixty percent of the breeder feed their animals on the pasture for 8-10 months and only 30% the breeders give supplementary feeding before and during mating period. The enterprises have 31.2% parturition chamber and 92.5% lamb growth areas. While all enterprises are routinely used to protective vaccines but only used disinfectant of 73.7% enterprises. The reason of sheep and goat breeders is majority contributions of income and habits. So, flock sizes are small (74.5 heads animal). In conclusion, young people by encouraging small animal farming in the province of Kastamonu, should be given to technical, economic support and educational seminars. In the future, as the sole source of income and a large flock size may lead to a development of sheep and goat breeding in Kastamonu province.

This study was carried out to determine the effects of additive feeding with pollen and water on honey yield, colony population, winter loses and wintering ability of colonies in pine honey production season in Muğla province of Turkey. Total twenty honeybee colonies had similar physiological pattern (queen age, genotype, amount of adult worker bees (number of frames covered with adult worker bees), sealed brood areas (cm2) and food stocks) were used and randomly divided into four groups. Three of them were fed extra with pollen+water, pollen and water. The control colonies were not given additive foods. Honey yield in pollen+water, pollen, water and control groups were found to be 24.2±1.1, 17.3±0.8, 16.3±1.0 and 12.0±0.6 kg/colony respectively. Group means were statistically significant. From September 25 to February 15 (wintering), losses of the adult worker bees in pollen+water, pollen, water and control groups were 50%, 69%, 68% and 82%, decrease of sealed brood areas in the groups were 48%, 66%, 68% and 85%, respectively. Wintering ability of pollen+water, pollen, water and control groups were found to be 92.1±3.2, 70.4±17.8, 67.1±16.7 and 51.0±21.2% respectively. The results showed that additive feeding in pine honey production season, especially feeding with both pollen+water provided nearly 100% more honey production and 80% better wintering ability than the control group. In addition, feeding with only pollen or water had similar positive effect (approximately 40%) better than control group

Beyhan Taş | Özlem Yılmaz | Işıl Kurt
Phytobenthos includes bioindicator species and is widely used in water ecology studies. Diatoms constitute one of the most important groups of phytobenthos in streams. In particular, these organisms are good indicators in investigations related with determining of water quality in medium and long time. In this study, the epipelic diatom flora of the lower part of River Melet were investigated, the most important source of drinking water in Ordu city. The examination was performed periodically in March-November 2012 and total of 56 taxa were identified. Cymbellales (14 taxa) and Naviculales (16 taxa) ordo constituted 54% of diatom diversity. These were followed by Fragilariales (16%, 9 taxa) Bacillariales (14%, 8 taxa) Surirellales (9%, 5 taxa) Achnanthales (3%, 2 taxa) Eunotiales (2%, 1 taxa) and Melosirales (2%, 1 taxa), respectively. Diatome vulgaris, Melosira varians, Navicula gregaria, N. tripunctata and Nitzschia sigmoidea species were recorded as widespread and intense in the epipelic communities. These species are usually tolerant to organic pollution and are found in β-α- mesosaprobic conditions. According to the obtained results, the lower part of the Melet River has character from pollution towards moderate pollution. In other words, it has II-III. class water quality.

Sezai Alkan | Özgür Barış Birgül
The aim of this study was to determine the effect of thermal manipulations during early and late embryogenesis on asymmetry in terms of sides of shank length, shank width and face length of broilers. Incubation conditions were 37.5°C and 55% relative humidity for control group throughout the incubation period until the 19th days. In the thermally treated eggs during early embryogenesis (8-10 days), incubation temperature was increased to 41°C and relative humidity to 65% for 3 hours (12.00-15.00) on the 8th-10th days of incubation. Also, in the late embryogenesis stage (16-18 days) incubation temperature was increased to 41°C and relative humidity to 65 % for 3 hours (12.00-15.00) on the 16th-18th days of incubation. Total 16 chickens were selected at randomly from all experimental groups to determine the asymmetry. The weekly left and right sides of shank length, shank width and face length of chickens were measured from 7 days of age to 35 days of age, and relative asymmetry values were calculated. There was no significant difference among the groups in point of relative asymmetry. Asymmetry values were reduced due to aging.
