2013
Arda Yıldırım | Ergin Öztürk
This study was conducted to determine the effect of cottonseed meal (CSM) incorporated into laying rations in place of soybean meal (SBM) at different ratios on yield traits. The birds began to lay at 6th week, 180 female and 45 male quails were used in laying period experiment. Birds were fed with rations containing 20% CP and 3000 Kcal/kg ME up to 20-week age (Laying period). CSM as a substitute, five different rations of the protein content (0, 30, 58, 86 and 100%) for SBM to basal diets based on corn-soybean meal were used. The results showed that there were no differences in terms of egg yield traits, cumulative feed consumptions and viabilities during the laying period. The highest dry shell rate and shell thickness were obtained from 5th group and 1st group, respectively. As a result, adding CSM instead of SBM in laying period were no significantly differences in terms of egg production and egg quality in laying period.

Filiz Uçan | Hatice Aysun Mercimek
Requirement simple technology, low production costs, lack of polluting effects and reliability in terms of health of it is the most important advantages of edible films. Chitosan that extend the shelf life of food and increase the economic efficiency of packaging materials is one of the new materials used for edible films. Chitosan was obtained by deacetylation of chitin which is the most commonly occurred polymer after cellulose in nature, in shells of arthropods such as crab, shrimp, lobster and in cell walls of some bacteria and fungi. Chitosan has the important bioactive properties such as hemostatic, bacteriostatic, fungistatic, spermicidal, anticarcinogenic, anticholesteremic, antacids, antiulcer, wound and bone healing accelerator and stimulating the immune system. As well as these features, the film forming and barrier properties of its, chitosan is made the ideal material for edible films and coatings in antimicrobial characters. Especially, in the protection of qualities and the improving storage times of fruits and vegetables, have been revealed the potential use of chitosan. The coating food with chitosan films reduces the oxygen partial pressure in the package, maintains temperature with moisture transfer between food and its environment, declines dehydration, delays enzymatic browning in fruits and controls respiration. In addition to, chitosan are also used on issues such as the increasing the natural flavour, setting texture, increasing of the emulsifying effect, stabilization of color and deacidification.

Mehmet Köten | Sabri Ünsal | Ayhan Atlı
Barley, as animal feed, raw material for malting and human food, constitute an important part among cereal sources in the world. Majority of barley that produced both in Turkey and other countries of the world, is being used as animal feed. Poor baking quality, taste and appearance of barley restricted its use in human nutrition. However, recently high protein, fiber, especially β-glucan and high starch content appeal to food industry. Many scientific researches established that β-glucan, a soluble fiber, has an effect in healing coronary-hearth diseases, lowering blood cholesterol level, balancing blood sugar level, preventing obesity. Being a healthy cereal that can be used in various purposes, and an additive in many food products, barley is considered a very promising cereal, and research to increase possibilities of its use in human nutrition is being increased. In the literature, there has been researches on making noodles, bulgur, kavut (roasted cereal), breakfast cereals. In this study the researches relating to evaluation of barley, importance of which is increased every day, as human food was reviewed.

Hasan Eleroğlu | Arda Yıldırım | Ahmet Şekeroğlu
The source of water, the content and quality is very important used in every stage of poultry production. The birds must have continuous access and supply of quality water without any antibiotic and bacteriological residues. Sensory, physiochemical properties and chemical composition must be taken into consideration while assessing water quality. The quality of water used in the production of conventional or organic poultry has impacts on the poultry health, quality of products and human health. The impact of water quality is higher on the functionality of water in live organism and the consumption amount varies depending on many factors. A source of water which is used in organic production is also important with their characteristics. Different water sources may be used for animal consumption, such as springs, shallow wells, deep and artesian wells, lakes and creeks. Organic farms should regularly submit water samples to a laboratory for testing of water quality against the possibility of contamination of water sources. Water contaminants could create equipment problems and restrict the amount of water available for consumption therefore affects the quality of products. There are many aspects to the broad problems of water quality and different physical and chemical applications used to ensure sustainability of water quality for human and animal use. In this review, it will be focused on the quality of the water to be used in the organic poultry production and quality enhancing physical and chemical applications.

Carrot produced in all seasons and can be consumed as fresh, cooked, boiled, garnish, juice and pickles. There is a great variation in carrot color from light yellow to dark purple-black. Because of the dark purple-black color and the high anthocyanin content, ‘Ereğli Siyahı’ cultivar is commonly used in the industry. However, ‘Ereğli Siyahı’ has wide variation within its population. In this study, the difference among the phytochemical content of ‘Ereğli Siyahı’ sampled grouped based on their interior color has been examined. Carrot roots grown in same field in Eregli, Konya were sampled and collected. Marketable 700 roots were from ‘Eregli Siyahı’ were randomly sampled. Then, the roots were cut in half and separated 11 different groups (G) according to the interior color. Each group was homogenized in 4 replications and samples were prepared for analysis of phytochemicals. Results of the study showed that G7 had the highest phenolic content (1199.23 µg GAE/g fw) while G5 was the group that had the lowest phenolic content (516.54 µg GAE/g fw). Antioxidant capacity was determined using TEAC ve FRAP methods. The highest TEAC (8.54 µg TE/g fw) and FRAP (15.52 µmol TE/g) were observed in G2. However, the lowest TEAC (2.09 µmol TE/g) and FRAP (1.62 µmol TE/g) were found in G5. The percentage of carrot roots was the highest in G2 (%35). The results indicated that there is a great deal of variation for several phytochemical traits within “Ereğli Siyahı”.

Gyromitra is one of the poisonous mushrooms with being evaluated as edible mushrooms in Turkey and in many countries. This study was performed to determine volatile aroma compounds of Gyromitra collected from Turkey at Horticulture Department of Çukurova University, Adana-Turkey in 2011. Gyromitra mushroom samples collected from Adana province of Turkey were used as material. Volatile aroma compounds were determined using Headspace Gas Kromotografi Mass Spectrometry (HS-GC/MS) technique. Twenty-four different volatile aroma compounds were detected in this study. Phenol was identified as the major aroma component at 47.10% content. This compound was followed with Carbamic acid methyl ester (14.12%), Acetic acid (4.47%), 1-Octen-3-ol (4.14%) and Acetaldehyde (4.10%). Phenol is an antioxidant compound and it has anti-carcinogenic effect. 1-Octen-3-ol is an alcohol which commonly found in mushroom. Acetic acid and Acetaldehyde are poisonous compounds. Although high number of phenol and 1-Octen-3-ol in Gyromitra fungus is displayed as flavor and significant in terms of health, containing toxic compounds such as acetic acid and the acid aldehyde raises the risk factors in exhaustion.

In order to study the quantitative variability of malting quality-related traits and to determine the genomic locations which control these traits, an experiment was conducted using one hundred fifty double haploid (DH) lines of barley and their two parents ‛Steptoe’ & ‛Morex’. Protein content (%) was measured using Kjeldahl method, diastatic power calculated with Lintner formula, Malt extract was measured for each by special weight achieved and based on Malt Berix Charts. Transgressive segregation in both directions was observed for all traits. Genetic map is fairly saturated and comprising 327 RFLP markers with a total length of 1226.3cM with an average marker spacing of 3.75cM. Seventeen QTLs by LOD≤2(LRS≤9.21) controlling different studied traits were identified for all studied traits. Total phenotypic variance explained by these QTLs varies from 23.2 to 45.05%. Highest LOD scores were obtained for QTL’s controlling diastatic power (Qdip3Ha) on chromosome 3H, and lowest LOD scores were obtained for QTL’s controlling seed yield per plant (Qsyp1Hb) on chromosome 1H. Therefore gain through marker-assisted selection (MAS) in this population would be limited and some of the “Steptoe× Morex” population was developed with the intention of isolating and advancing barley lines for release to the malting quality.
