The aim of this study is to determine the slaughter and carcass traits of White and Multicolor Geese varieties reared in Yozgat province. 5 female and 5 male geese at six months old age from each variety were slaughtered and their slaughter and carcass traits were presented. Also, phenotypic correlations between carcass traits were calculated. The differences between the slaughter weight, hot and cold carcass weight, feather, head and foot weights of varieties were found insignificant, while male geese had higher values in terms of these traits. There were no significant differences between varieties and sexes in terms of hot and cold carcass yields and head ratio. Feather and foot ratios were found higher in White geese; whereas, abdominal fat ratio was found higher in Multicolor geese. There were insignificant differences between varieties in terms of carcass part weights, except back weight which was found higher in males. While heart weights of male geese were significantly higher, differences between varieties and sexes in terms of liver and gizzard weight were found insignificant. There were insignificant differences between the carcass parts and edible inner organ ratios of varieties, but breast ratio of females was found higher, while back ratio of males were found higher. Phenotypic correlation coefficients between slaughter weights, carcass weights and hot-cold carcass yields were found significant. Obtained data showed that native geese in the region are suitable for meat production in terms of slaughter and carcass traits.

In order to determine the effects of nutrient (P, Si, NH4, NO3) enrichment on the growth of phytoplankton in Homa Lagoon (İzmir Bay, Aegean Sea), experiments of enrichment with discontinuous cultures have been executed seasonally in 2007. In our study, the elements limiting the growth of phytoplankton were NO3, P and Si in spring season, N and P in summer season, and NH4 in autumn and winter seasons. So, it has been determined that the addition of nitrogen (N) and phosphor (P) has led significant change in biomass and growth of phytoplankton. It has also been observed that diatom and dinoflagellate species have grown under various concentrations of, especially, Silicate (Si) and nitrogen (N).

Mastitis is an important disease which causes economic losses in the water buffalo breeding. According to severity, duration and primary, mastitis is generally classified as clinical and subclinical. Because of contamination from other animals in the herd, subclinical mastitis is a important dairy herd problem. However, clinical mastitis is a clinical case created by deformation of udder gland and decreasing milk yield. Staphylococcus aureus, Escherichia coli, Streptococcus agalactia and Streptococcus dysgalactia are in clinical mastitis, but Escherichia coli, Staphylococcus aureus, Pseudomonas, Streptococcus agalactia and Streptococcus dysgalactia are the most common isolated microorganisms in subclinical mastitis. Due to mastitis caused by these microorganisms in Water Buffalo, abnormality in the structure of milk are observed, and it causes economic losses to farmers from reduced production. Therefore, the detection of effective factors on mastitis and taking of the necessary precautions are very important. In this review, mastitis case in water Buffalo and its effects were discussed.

Sage, which belongs to Labiatae family and contains essential oils, is a typical Mediterranean plant. Being an important and one of the biggest species of this family, sage is said to be named being inspired by the word "Salveo" which means “saver” or “healer” in Latin. Salvia genus is represented by about 900 species on earth. There are 97 natural species of this genus in Turkey’s flora. There is dormancy in seeds of Salvia genus and having mucilage-like seed-coats is an inhibiting factor for germination. Seed germination studies of these species are of great importance in determining production strategies. This research is carried out at 25/15°C, 12 hours in light and 12 hours in dark environment to determine the effects of various germination applications (ethylene, gibberellin, PEG 8000, salicylic acid and seaweed) and pre-treatments (pre-drying, pre-cooling and untreated) in four species (S. fruticosa, S. officinalis, S. pomifera, S. tomentosa). These trials were conducted at the Department of Field Crops Laboratory of Adnan Menderes University according to completely randomized design with three factors with three replications. Important differences were observed about the germination rate and germination power among the species.

The aim of this study was to determine the main spermatological properties in Carasobarbus luteus (H., 1843) and Carassius carassius (L., 1758) in Atatürk Dam Lake. Sperm was collected by abdominal massage from thirty C. luteus and twenty C. carassius. Milt volume (ml), spermatozoa motility (%), motility duration (s), spermatozoa concentration (x109/ml) and pH in C. luteus and C. carassius were 0.72±0.08 ml and 1.03±0.20 ml, %57.67±3.67 and % 81.00±1.43, 190.30±11.25 s and 107.30±12.03 s, 13.15±1.33 and 10.53±1.28x109/ml, 8.13±0.11 and 7.60±0.04, respectively. The spermatozoa motility, motility duration, spermatozoa concentration and pH was found significant compared with fish species group.

Concentrations and profile of polycyclic aromatic hydrocarbons(PAHs) and metals (Cd, Pb, Ni, Cr, Fe and Mn) were determined in selected brands of canned maize in the Nigeria market with a view to providing information on the hazards associated with the consumption of these products. The measurement of the concentrations of PAHs was carried out by using a gas chromatography equipped with flame ionization detector (GC-FID) after extraction by ultra-sonication with acetone/dichloromethane and clean-up. The 16 PAH concentrations varied between 45.1 and 335.7 µg/kg. The concentrations of the indicators for occurrence and effects of PAHs in food varied from 3.6 to 114.5 µg/kg for BaP, 6.4 to 168.2 µg/kg for PAH2, 11.8 to 232.7 µg/kg for PAH4 and 19.4 to 327.3 µg/kg for PAH8. The concentrations of metals were determined by using atomic absorption spectrometry after acid digestion. The concentrations of metals in these samples ranged from

A small scale pilot biodiesel production plant that has a volume of 65 liters/day has been designed, constructed and tested. The plant was performed using oil mixture (50% wild mustard seed oil + 50% refined canola oil) and methanol with sodium hydroxide (NaOH) catalyst. The fuel properties of biodiesel indicated as density at 15oC (889.64 kg/m3), kinematic viscosity at 40oC (6.975 mm2/s), flash point (170oC), copper strip corrosion (1a), water content (499.87 mg/kg), and calorific value (39.555 MJ/kg), respectively.

Microbial population of soil and its structure is affected with chemical and biological changes such as plant-root secretions. Upper layer of the soil is exposed to mixture of stems, fruiting bodies and leaves of trees. Seven trees growing at same area were chosen. Their upper layers of the soil were collected from depth 5-10 cm as samples in spring and autumn. Their microbial populations were investigated in order to determine in terms of climate changes. In order to determine the number of the total microorganisms, gram-negative bacteria and spore-forming bacteria (cfu/g) were used by the serial dilution techniques. As a result, the highest numbers of microorganisms from the soil of the apple tree were determined as the total microbial count in the autumn, although the lowest number of microorganisms was obtained from the soil of the pine tree. However, the number of the gram-negative bacteria was the highest in the soil of linden tree, although the number of gram negative bacteria was the lowest in the soil of apricot, mulberry and apple trees. For spore - forming bacterium, the highest number from the mulberry soil and the lowest number from the linden tree have been obtained. In the spring, the highest numbers of microorganisms from the soil of the apple tree were obtained as the total microbial count, although the lowest number of microorganisms was obtained from the soil of the apricot tree. For the number of the gram-negative bacteria was the highest in the soil of walnut tree, although the number of gram negative bacteria was the lowest in the soil of apricot trees. However spore - forming bacterium, the highest number from the soil of the poplar tree and the lowest number from the mulberry tree have been obtained. In general, the rich diversity of the microbial population was shown morphologically in autumn.

In this study, the interaction between potato production and its price from 1991 to 2012 was analyzed using Koyck approach, one of the distributed lag econometric models. The amount of potato production can increase or decrease in the current year based on the prices of previous year, as a product that is appropriate for cobweb theorem, one of economic facts. According to the results of Koyck model, it was determined that potato was affected by the prices of maximum two years retrospectively, and that 1.45 years were needed so that the change in potato prices could have a significant and considerable effect on potato production. On the other hand, while a TL 1 increase in potato prices in the current year increased potato production 711151.80 tons, a TL 1 increase in the prices of previous year increased the production 421001.86 tons and a TL 1 increase in potato prices two years previously caused 249233.10 tons increase in production. In conclusion, the following issues can be considered as measures to be taken economically: creating producer-consumer chain by setting up effective marketing organizations and therefore avoiding problems such as surplus supply or surplus demand, creating both more efficient and better quality production structure by planning the production, and providing stable production and stable price policies by establishing supply and demand balance.
