The present study was conducted to investigate the carcass traits of Karayaka lambs slaughtered at different slaughter weights (SWs) and to find out optimum SWs. Male Karayaka lambs with 20 kg live weight (n=30) constituted the animal material of the study. Lambs were randomly divided into five SW groups; 30 (GI; n=6), 35 (GII; n=6), 40 (GIII; n=6); 45 (GIV; n=6) and 50 (GV; n=6) kg. Lamb fattening feed (concentrate feed, ad libitum) and forage (lentil straw, 100g/lamb/day) were used as the feed material. Lambs were sent to slaughter at target SWs. Following the slaughter, non-carcass components, tailless hot and cold carcass weights were taken. Carcasses were separated into six sections as leg, foreleg, back, loin, neck and others. Physical dissection was performed to investigate carcass composition. Only the differences in carcass dressing and skin percentages of slaughter groups were not found to be significant. Increasing carcass fat percentages and decreasing carcass lean and bone percentages were observed with increasing SWs. Considering the consumer preferences, current findings revealed that Karayaka lambs should be sent to slaughter at weights between 30-35 kg. However, considering the red meat deficit of the country, current market conditions and producer preferences, the optimum SW for Karayaka lambs were recommended to be between 40-45 kg.

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.

The possible use of three different thickness black geotextile materials (GEO-50, GEO-100 and GEO-150) , the new control methods for our country, compared with weedy check among of the rows and using herbicide (Glyphosate), mowing, black polyethylene with weedy check on the rows have been investigated for controlling of weeds which is a considerable problem of tangerine orchard. Experimental randomly plots were arranged by considering complete block design with five replications on the rows treatment. Mulch materials were applied apart for width of 160 cm on the rows. When weed coverage (%) reached 10-15%, herbicide (Glyphosate) was applied with 600 cc/da. Mowing was applied when weed lenght and coverage (%) reached 10-15 cm and 10-15, respectively. Weed coverage (%) and numbers were counted in 15 days intervals at the quadrats for all plots. The results of the studies for tangerine orange 4 years old showed that mulching with black geotextile and polyethylene were more supressed than the other control methods on the row. Average weed coverage (%) was found 56.09% in control (weedy), 24.66% in mowing, 11.05% in herbicide, 3.09% in black polyethylene, 2.78% in GEO-50, 0.87% GEO-100 and 0.76% JEO-150, respectively. As observed weed coverage (%), the similar result was found for weed number in black geotextile treatments.

Wheat take-all disease caused by Gaeumannomyces graminis var. tritici has recently been detected in different regions of Iran. With respect to biocontrol effect of Trichoderma spp. on many pathogenic fungi, seven isolates of Trichoderma and four isolates of Talaromyces were in vitro evaluated in terms of their biological control against the disease causal agent. In dual culture test the five isolates showed efficient competition for colonization against pathogenic fungus and the highest percentages of inhibition belonging to Talaromyces flavus 60 and Talaromyces flavus 136 were 59.52 and 57.61%, respectively. Microscopic investigations showed that in regions where antagonistic isolates and Gaeumannomyces graminis var. tritici coincide, hyphal contact, penetration and fragmentation of Gaeumannomyces graminis var. tritici were observed. Investigating the effect of volatile and non-volatile compounds at 10 ml concentration showed that the highest inhibition percentage on mycelium growth of the pathogen caused by T. harzianum (44.76%) and T. longibrachiatum (52.38%) respectively.

In this study, the effects of lactococcin BZ from Lactococcus lactis ssp. lactis BZ and enterocin KP from Enterococcus faecalis KP (1600 AU/mL) on the activities of three different yoghurt cultures (Y1 and Y2: CHR Hansen, Denmark; Y3: Sacco, Italy) were investigated. Lactic acid bacteria counts and pH values of the samples were determined during the incubation period (at 42°C for 24 h). It was found that lactococcin BZ had bactericidal effect against only one yoghurt culture whereas enterocin KP was effective against two yoghurt cultures. When lactococcin BZ and enterosin KP were used in combination (1:1), they showed bactericidal effect against two yoghurt cultures.

The purpose of this study was to investigate the possible presence of sesame in commercial foods normally carrying no warning for the allergen, but which may have been subjected to contamination during processing. One hundred units of widely consumed goods with high potential to contain allergenic substances deriving from nuts were analyzed, using sensitive and capable PCR (C-PCR) and Real Time PCR (RT-PCR) methodologies. Of the products examined, 15 (15.0%) declared the presence of sesame, 36 (36.0%) carried no food allergy label, 44 (44.0%) were marked by the phrase “may contain traces of nuts” and 5 (5.0%) carried the indication “may contain sesame traces”. The sesame-positive products detected using the C-PCR method were 15 (100%), 12 (33.3%), 14 (31.8%) and 3 (60%), respectively. Using the RT-PCR technique, positive results were obtained for 15 (100%), 18 (50.0%), 18 (20.5%) and 5 (100%) samples, respectively. The results indicate that the PCR methods applied are highly sensitive and selective, which makes them suitable for the detection of sesame traces in food samples. In addition, they can be useful for monitoring the effectiveness of cleaning processes in the production units of the food industry.

Using primary energy sources in World as fossil fuels, causes air pollution and climate change. Because of these reasons, people looking for renewable energy suppliers which has less carbondioxide and less pollution. Carbon in biofuels is producing from photosynthesis. For this, burning biofuels don’t increase carbondioxide in atmosphere. Scientists predict that plants with high carbonhydrate and protein contents are 21. centuries biofuels. Potatoes are producing over 280 million in whole world and Turkey is 6th potato producer. Turkey produces 5250000 tonne of potatoes. Approximately 20% of potatoes are waste in Niğde. Our study aimed to produce bioethanol from Solanum tuberosum by using the yeast Saccharomyces cerevisiae. As a result renewable energy sources can be produced from natural wastes.

Fruit and vegetables are an important component of a healthy diet and the main antioxidant suppliers in the human diet. Consumption of foods derived from fruits and vegetables is also essential; fruit juices, ciders, wines, and vinegars also contain significant amounts of polyphenolic compounds. The aim of the study was to determine the effect maceration of antioxidant activity and phenolic content of apple cider. Red delicious apples were used to produce natural apple cider with and without inclusion of maceration. Samples were taken from fresh red apple juice, macerated samples and apple cider. Apple cider (maceration was applied) (CAM) had the highest total phenolic content, chlorogenic acid, ORAC and TEAC levels. Chlorogenic acid was the dominant phenolic substance in apple juice and cider samples and chlorogenic acid was increased with maceration process.

The study was designed to determine the consumers’ attitude and behaviors towards poultry meat consumption and to analyze the factors affecting on their meat consumption. The data obtained from 385 households consuming the poultry meat and residing in Erzurum province. As the data set based on Principal Component Analysis to determine the main factors affecting the consumption according to the poultry meat attributes and K-means Cluster Analysis to constitute the homogenous segments related to their consumption frequencies were used. According to the results of the study; the heavy users (C1) consuming the poultry meat consumption constituted the desirous and sensitive consumer segments based on both product image and price-sensitive contributing to the regional and rural development under the augmented product mix registered with the origin of the region. On the other hand, while the medium users (C2) focused on the concept forming their diets under the core benefit and the disease risk of the poultry meat by considering the sensorial and main quality attributes, light users (C3) also tried to maximize their total utility through products with generic brand. Therefore, it could introduce the augmented product mix under the product strategies with local brand with the origin of region for C1, the private brand strategies meting ISO 9001 and HACCP standards for C2, and the generic branded product with the origin of region in accordance with the product image for C3. In this way, it could be contributed to the rural regional developments, and thus could be increased the welfare levels of the people living in the rural areas by providing both the producer and consumer satisfactions.

This study was carried out to determine and compare the proximate composition and length weight relationship of C. gariepinus from two culture systems (earthen and concrete ponds). The fish samples were collected from three fish farms with same cultural condition in different areas of Obio-akpor Local Government Area of Rivers State, Nigeria. Result on the length- weight relationship revealed that C.gariepinus reared in concrete tank had a total length of 15.50- 49.00cm with a mean of 32.71cm and weight of 150-625g, while total length of C. gariepinus reared in the earthen pond ranged from 19.90-58.0cm with a mean of 39.8cm and weight of 195-825g. The T- test shows that the total length of earthen pond were significantly higher than the concrete tank and the weight in the earthen pond was significantly higher than the concrete tank. Parameters of proximate composition analysed were moisture, protein, lipid, carbohydrate, ash and fiber from the fish flesh. Protein content showed a significantly higher in the earthen ponds than the concrete tanks. Ash contents varied from 1.5±1.66-7.4±0.67% in the concrete tanks and were significantly higher than the earthen ponds which ranged from 3.1±0.94-4.5±2.11%. Lipid was significantly higher in earthen ponds than concrete tanks. Generally, the two culture systems have a significant influence on length–weight relationship and nutritional value of C. gariepinus. However, C. gariepinus reared in concrete tank had a heavier body weight than earthen pond and also C. gariepinus reared in earthen pond had highest nutritive values than the concrete tank.
