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.

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.

Concentrations of selected metals (Cu, Cd, Ni, Pb, Mn, Fe, Zn, Cr and Co) in some ready-to-eat-foods consumed in Nigeria were investigated with a view providing information on the risk associated with the consumption of these products. The concentrations of metals (mg.kg-1) in these ready-to-eat-foods are in the ranges of 2.4 – 5.2 for Cu; 0.1– 0.8 for Cd; 0.7 – 4.0 for Ni; 8.1 – 53.7 for Fe; 8.9 – 20.0 for Zn; 0.1 – 3.8 for Pb; 5.1 – 14.4 for Mn; 0.83 – 21.4 for Cr and 0.20 – 1.32 for Co. The concentrations and estimated intakes of Cd, Ni and Pb in some of these food types exceeded the permissible limits and tolerable daily intake respectively. The target hazard quotients (THQ) for the individual metals indicate levels of concern for Ni, Cd, and Co in some of the ready-to-eat-foods. The combined THQ values for the metals in the examined samples ranged from 1.7 to 10 with significant contributions from Cd, Ni and Co.

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.

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.

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.

This study contains the yield evaluations on oilseed crops cultivation in TR71 region, which contains Niğde Kırşehir, Aksaray, Niğde and Nevşehir provinces and is also known as Ahiler Development Agency. Effects of climate change on oilseed crops based on climate projections of the next 30 years was have been analyzed. Changes in surface temperature values and precipitation amounts for the period of 2011-2041 have been evaluated seasonally and annually with the corresponding values of 1961-1990(RF). Based on the RegCM3-ECHAM5-A2 scenario, the average temperature is expected to increase 0.2-0.6 Co until 2041. The smallest temperature change is predicted to occur in spring season where the greatest temperature change (0,6-0,8C°) is expected to occur in summerand autumn season. The changes in total annual precipitation amounts had generally increase tendency (5-25%) over the region especially in winter season30% increase rate was expected over Kırşehir, Aksaray and South part of Kırıkkale province. The changes in total autumn season precipitation amount is predicted to increase (20%) over Niğde but decrease (5%) over the south part of Kırıkkale and southwest part of Kırşehir and Aksaray province in autumn season. Considering the effects of the climate change in the next 30 years, agricultural production in TR71 region is in quite a good place compared to other part of Turkey but this change will indeed affect the agricultural potential of the region substantially. Annual temperature elevation will aggravate the plant temperature stress where increased evaporation will negatively impact the yield, increasing the pressure on the limited irrigation potential. Especially elevated temperature will negatively impact disc development during the seed formation period resulting in yield loss because of the feeble seeds on the disc and the increased disease susceptibility resulting from the cavitation in the inner parts of the disc.

Ayhan Ceyhan | Mahmut Çınar | Ugur Serbester
This study was carried out to investigate the effect of udder measurements group on somatic cell count (SCC) and daily milk production. Milk samples and udder measurements were collected monthly from 79 lactating Holstein cows on commercial dairy in the province of Niğde. In the study, front teat length (FTL), rear teat length (RTL), front teat diameter (FTD), rear teat diameter (RTD), distance between front teats (DBFT), distance between rear teats (DBRT), front udder height, (FTH), rear udder height (RUH), distance between front and rear teats (DBST) were obtained in before afternoon milking. Udder measurements were divided into 5 groups according to the measurements. The effect of DBFT, DBRT, FTH, RTD, FTD and DBRT groups on daily milk production were statistically significant, while FTH, RUH and DBRT were found non-significant. The effect of udder measurements groups on SCC was found not significant, except rear teat diameter (RTD). Average daily milk production and SCC were estimated as 28.25 kg/day and 274.90 cell/ml, respectively. In conclusion, it can be said that the distance between teats, teat’s diameter and front udder height of Holstein cattle is important factor for milk yield of Holstein dairy cattle. Also, SCC is effected by rear teat diameter.
