This study was conducted to determine the current status of dairy cattle farms in Niğde, to detect basic priority problems and to offer some solutions. In the study, representing all provinces, total 95 dairy farms selected by stratified and random sampling method was taken. The data obtained from the surveys in farms, face-to-face was used. The results showed that the large portion of dairy cattle breeders (60%) were primary school graduates, the average duration of cattle breeding was 15.2 years, a significant proportion of labor (92%) of family labor was used, 54%, 19%, 15%, 6%, 4% and 2% of farms reared only Holstein, Holstein and Simmental, only Brown Swiss, only Simmental, Holstein and Brown Swiss, and Simmental and Brown Swiss respectively, the average number of animals per farm was 33, the number of dairy cows was 13, the average daily milk yield per lactating cow was 16.6 kg. Farmers agreed that the most important problems were the high cost of basic inputs, concentrated feed problem, low cost of products sold, roughage and pasture problem. In addition, according to Likert scale, the most satisfied activities were reared cattle breed (3.95), breeder’s organization services (3.94), milking process (3.76), calving and maintenance duties (3.74) and recording system (3.71). Beside, for the breeders, the worst issues were satisfied that Ministry policies about cattle breeding (1.83), sales price and the market situation of animals (1.96), sales price and the market situation of the milk (2.04), provision of essential inputs such as feed and labor costs (2.06), credit and financial support (2.08).

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.

2013
Senay Ozgen | Saziye Sekerci
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”.

Ayhan Ceyhan | Uğur Serbester | Mahmut Çınar | Adnan Ünalan | Ethem Akyol | Ahmet Şekeroğlu
The Central Anatolia Region is one of the seven geographical regions which are 151 thousand square meters of surface area and it is about 21.0% of Turkey's land area. The population rate of cattle breeds in the Central Anatolia Region is 20.4% exotic cattle breeds, 19.1% crossbred, 11.6% native cattle breeds and total 18.1% in Turkey. The Central Anatolia Region cattle population is consists of 43.9% of exotic breed, 43.5% crossbred and 12.6% the native cattle breeds. The population of exotic cattle breeds (69.5%) in Nigde province is the first place and followed by Eskisehir provinces rate of 65.6% in the Central Anatolia Region. The rate of crossbred cattle population is the highest rate (65.0%) province of Sivas and followed by Çankırı province (62.8%). Ankara and Yozgat province has the highest rate of native cattle breed 28.3% and 25.5%, respectively. The total populations of cattle breeds in Konya and Kırıkkale provinces were found maximum 518.291 cattle and minimum 45.426 cattle, respectively, in the Central Anatolia Region. The population rate of exotic and crossbred cattle breeds has increased 67.0% and 11.8%, respectively, while population rate of native cattle breeds has decreased 30.3% from 2007 to 2011 in the Central Anatolia Region. The 20.1% of sheep, 8.2% of goat and 18.3% rates of total livestock population in Turkey are in the Central Anatolia Region. The population rate of sheep and goat of the Central Anatolia Region is 20.1% and 9.5%, sheep and goat respectively and 18.3% total in Turkey. The 70.9% for Angora goats, 8.2% hair of goats, and 17.7% indigenous of sheep breeds and 66.0% crossbreed to national Sheep and Goat population has risen in the Central Anatolia Region. All of these results are evaluated, Central Anatolia Region, Turkey, the contribution of animal products grown by population of cattle and small ruminants is important and can be considered a center of attraction for investment in animal breeding

2013
Hatıra Taşkın | Gökhan Baktemur | Ebru Kafkas | Saadet Büyükalaca
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.
