In this study, economic structure and problems of trout enterprise were analysed in Fethiye district. It was aimed to determine the input of enterprises engaged in aquaculture at the Fethiye district, calculation of the economic situation, investigation of the market situation and determine problems. In addition possible solutions were tried to be to problems. In the district, it was interviewed with 17 trout enterprises. Data were collected with interviewing face to face by questionnaires. These data was analysed by MS Excel and SPSS programmes. 52.9% of the enterprises were established in the foothill, 35.3% were in open field and 11.8% were established in between valleys. 58.8% of these enterprises were individual enterprises, %17.6 was simple partnership and 23.5% were commercial partnership. The most shares in the active capital were constituted working capital with a rate of 70.3% whereas the share of landlord’s capital was 29.7%. The share of own capital in passive capital was 93.9% and the usage of foreign capital was low (6.1%). The share of variable cost was 83.6% while fixed cost was 16.4% in the total production cost. The main problem of enterprises was the rise of feed costs. A feed cost was found to constitute 63.4% of total production costs. Producers should be given support in terms of technical knowledge and efforts to raise awareness of local people and consumers should be made.

The aim of this study was to investigate some chemical characteristics and residual nitrite and nitrate levels of sucuk and salami samples collected from retail outlets of major supermarkets in Adana province. A total of 36 sucuk samples (12 brands; 7 national and 5 local producers) and 30 salami samples (10 brands; Macar salamis) were purchased from local markets. Sucuk and salami samples were analyzed for pH value, moisture content, water activity and nitrite and nitrate contents. The average pH values of sucuk samples ranged between 4.69 and 6.56 indicating a higher variation while the average pH values of salami samples ranged between 6.05 and 6.43. Likewise, the average moisture contents of sucuk samples were between 33.56% and 46.78% whereas the average moisture contents of salami samples ranged between 62.09% and 67.91% indicating a relatively lower variation. Water activity values of the sucuk samples were between 0.932 and 0.861 while the average aw values of the salami samples ranged between 0.916 and 0.940. Among the sucuk samples analyzed in the present study mean nitrite and nitrate contents ranged from 58.65 mg/kg to 216.63 mg/kg and 34.86 mg/kg to 161.08 mg/kg, respectively. While relatively lower nitrite (14.30 mg/kg - 35.96 mg/kg) and no nitrate contents were observed in salami samples, the data indicated that a higher variation of both nitrite and nitrate contents were still present in sucuk samples in the local markets requiring more studies and inspections to lower the variation related to dietary exposure to nitrite and nitrite from these types of products.

The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm), chest width (mm) and body length (mm) with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

In this study, physical, chemical and microbiological properties of 50 raw bulk milk samples obtained from 5 different dairy plants in the Sivas were investigated. The pH, acidity, fat, non-fat dry-matter, total dry matter contents and density of raw milk samples were 4.89-6.70, 0.135-0.495%, 1.7-7.6%, 7.33-9.80%, 10.00-16.90%, and 1.0230-1.0312 g/mL, respectively. Fat content of the 26%, specific gravity of 28%, total dry matter of 32%, solids-non-fat of 58%, pH value of 84% of the milk samples were found lower whereas titratable acidity of 60% of the samples were determined higher than the values stated in the Turkish Food Codex and in the Raw Milk Standard. Total coliform bacteria counts of 30%, total aerobic mesophilic bacteria counts of 88%, and somatic cell counts of 40% of the samples were higher than 1100 MPN/mL, 100000 cfu/mL and 500000 cell/mL, respectively. Yeast-mold counts of 72% of the milk samples were found between 104-106 cfu/mL.

Samanların hücre duvarında bulunan lignoselüloz kompleksin parçalanması ile selüloz ve hemiselüloz gibi rumen fermantasyonuyla sindirilebilir fraksiyonlar elde edilir. Rumende sindirilmeyen ligninin biyoteknolojik metotlarla parçalanarak samandan yararlanılabilirliğin artırılması son yıllarda hayvan beslemecilerin odak noktası olan alanlarından birisi olmuştur. Lignoselüloz kompleksin biyolojik metotlarla muamelesinde bakteriler, mantarlar ve bu mikroorganizmalardan elde edilen enzimler kullanılmaktadır. Bakteri muamelesinde Mycobacterium, Arthrobacter ve Flavobacterium türü bakterilerin lignini parçalayabilme özelliğinden yararlanılmaktadır. Enzim muamelesi etkili olmasına rağmen yüksek maliyet nedeniyle uygulamada yer bulamamıştır. Mantar muamelesinde beyaz, kahverengi ve yumuşak çürüme yapan 3 tür mantar kullanılmaktadır. Kahverengi çürükçül mantarlar tercihen selüloz ve hemiselüloza saldırır, ancak lignini parçalayamaz. Beyaz çürükçül mantarlar lignine saldırarak lignol bağları ve aromatik halkayı parçalarlar. Beyaz çürükçül mantarlar selülaz, ksilanaz gibi hidrolitik enzimlerle polisakkaritleri ve lignin peroksidaz ve lakkaz gibi oksidatif ligninolitik enzimlerle lignini parçalarlar. Lignoselülozik materyalleri en iyi parçalayabilen mikroorganizmaların mantarlar olması ve maliyetin düşük olması nedeniyle özellikle beyaz çürükçül mantarların uygulama potansiyeli bulunmaktadır. Bu bildiride biyoçeşitliliğin sağladığı avantajla biyolojik metotlarla samanların sindirilebilirliğinin artırılması tartışılacaktır.

Meat is one of the main nutrition source in the human diet with its excellent protein, vitamin and mineral contents. Despite its advantages, being high-priced makes meat products open to adulteration. Meat products are mixed food types which can contain different species of meat. However, mixing two or more types of meats is not always allowed by laws. On the other hand, replacement high quality meats with cheaper meat types are a cost lowering way for the producers. The commonly consumed meat types differ from country to country, but generally economical, ethnic and religion concerns are in the foreground. In this case, species identification techniques are gaining importance. Although some techniques depending on DNA or spectroscopy have been developed for many years, choosing the best method for species identification is still among the controversial issues today. Thus, the currently used methods and promising techniques in this area were discussed in this review.

In the study it is aimed to determine the stabilities of some agronomic traits of 10 different durum wheats over the years in conditions of Bursa. Research was carried out in randomized complete block design with three replications between the years of 2008-2013. Averages of genotypes of agronomic characteristics, Eberhart and Russell’s regression coefficient and deviation from regression, Francis and Kannenberg’s coefficient of variation and environmental variance used as stability parameters. When the results of the study evaluated at the stability analysis, Amb × Çak-30 lines were determined to be stable in most of the agronomic traits. As for grain yield, which is of great importance for the producer, breeding lines of Amb × Çak -26 and Amb × Çak-30 were determined in good harmony at Bursa under different climatic conditions over five years.

This study aimed to identfy chemical composition, ruminal degradation characeristics and metabolizable energy (ME) content of five different chickpea line and a check cultivar’s straw using nylon bag technique. Feed samples were incubated as three replicates of each fistulated Holstein heifer for 0, 8, 12, 24, 36, 48, 72 and 96 h. Degradation characteristics of dry matter (DM) and neutral detergent fiber (NDF) in rumen were determined by using this mathematical expression D=a+b(1-e-ct). Crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), and ash contents of straw were ranged from 5.61 to 7.42%, 51.33 to 56.0%, 63.67 to 67.0%, and 8.0 to 9.0% respectively. Besides Rapidly soluble fraction (a), potantial degradability (a+b) and effective dry matter degradability (EDDM ) were ranged from 17.86 to 21.41, 54.40 to 59.43, 49.65 to 54.91% respectively. Estimated ME of chickpea entries straw were ranged from 5.96 to 7.37 MJ/kg. Metabolizable energy content of control chickpea cultivar was significantly higher than the other chickpea straw of lines. The research values of ME revealed that significant differences were determined among the lines in terms of energy content. In addition to, a strong relationship between straw NDF level and ME content were determined.

In this study it was aimed to produce a commercial aquatic plant Vallisneria spiralis in a controlled- aquaculture system. In order to determine the potential of the plant to utilize different nutrient resources relative growth rate depends on biomass yield and individual plant number and length composition of V. spiralis cultivated in semi-shadow and non-shadow conditions were determined. Results of the present work showed that V. spiralis utilized different nutrient resources effectively such as cow, lamb, chicken and commercial fertilizer TSP in cultivation conditions and increased its weight and individual number compare to the control group where nutrient addition is not applied. In semi-shadow condition V. spiralis fresh biomass yield and plant number increase were the highest in cow group and found to be 1.52%±0.03 g.day-1 and 1.80%±0.05 individual.day-1 respectively. The mean length of V. spiralis was found to be the highest (83.56±26.14 cm) in lamb fertilizer group. In non-shadow conditions V. spiralis fresh biomass yield and plant number increase were the highest in cow group and found to be 2.73%±0.07 g.day-1 and 2.52%±0.6 individual.day-1 respectively. The mean length of V. spiralis was found to be the highest (92.74±27.93 cm) in cow fertilizer group as well.

Günümüzde piyasada bulunan probiyotikler, genellikle fermente süt ürünleri şeklindedir. Süt tüketimi, süt ürünlerinin kolesterol içeriği ve laktoz intoleransı sebebiyle sınırlanmaktadır. Ayrıca, bazı gelişmekte olan ülkelerde fermente ürünlerinin kullanımını kısıtlayan gelenekler ve ekonomik nedenler, alternatif gıdaların probiyotikler için taşıyıcı olarak kullanılması fikrini öne çıkarmaktadır. Bu sebeplerle et ürünleri, tahıllar, baklagiller, meyveler ve sebzeler, probiyotik mikroorganizmaların substratları olarak tüketicilerin ilgisini çekmektedir. Bu ürünlerin geliştirilmesi hem endüstriyel, hem de bilimsel açıdan önemli bir araştırma alanıdır. Bu çalışmada, süt kaynaklı olmayan probiyotik gıdalar hakkında bilgiler verilmiş ve bu alanda yapılan araştırmalar vurgulanmaya çalışılmıştır.
