Just because of geographical spread, citrus species generally grow in places sensitive to salinity. Testing methods have a significant role in breeding and cultivar development programs. This study was conducted to investigate in vitro salt response of Cleopatra mandarin (Citrus reshni Tan.), sour orange (Citrus aurantium L.), rough lemon (Citrus jambhiri Lush.), Volkamer lemon (Citrus volkameriana Tan & Pasq.), Carrizo citrange (Poncirus trifoliata L. Raf. X Citrus sinensis L. Osbeck) and trifoliate orange (Poncirus trifoliata Raf.) rootstocks at different NaCl concentrations. Seeds were germinated in MS medium with 0, 45, 90 and 135 mM NaCl concentrations. In general, the greatest germination rates in all salt concentrations in Volkamer lemon and sour orange rootstocks and the lowest values were observed in rough lemon and trifoliate orange rootstocks. Present findings revealed that in vitro conditions could reliably be used in salt tolerance tests of citrus rootstocks.

In recent years, youth unemployment in Turkey is the effect of economic growth on employment and unemployment.

In this article, the definition, the structures, the types, the sources of production, the application areas, the microorganisms they act on and the mechanism of action of antimicrobial peptides and information about the studies related to their use in poultry nutrition will be given.

Rainbow trout, a salmonid species has an economic importance worldwide and contributes to the indigenous food security. The present study was conducted in complete randomized design (CRD) to evaluate the dietary inclusion of citric acid with phytase as supplement on growth responses of rainbow trout. There were four treatments of diets with 0.5% citric acid (T1), 1% citric acid (T2), 1.5% citric acid (T3) and 0% control (T4) of citric acid incorporated with 1200FYT phytase as supplement. The treatments were replicated three times. Total harvest weight of fish in T3 (5720.2±105.6g) was significantly higher and different than T2 (4595.9±434.9g), T1 (4589.8±240.2g) and T4 (4567.5±217.3g). The highest daily growth rate was seen in treatment T3 (1.1±0.0) which was significantly different than T2 (0.9±0.0), T1 (0.9±0.0) and T4 (0.8±0.0). The highest specific growth rate was seen in the treatment T3 (0.8±0.01) which was significantly different than T1 (0.7±0.0), T2 (0.7±0.1) and T4 (0.7±0.0). The lowest food conversion ratio was seen in T3 (2.2±0.1) which was significantly different with T2 (2.6±0.1), T1 (2.7±0.1) and T4 (2.8±0.1). Similarly, the highest protein efficiency ratio was seen in treatment T3 (1.0±0.1) which was not significantly different with T2 (0.8±0.0) and T1 (0.8±0.1) but was significantly different than T4 (0.7±0.0). No significant changes were observed in water temperature, dissolve oxygen and pH under different treatments. The present findings demonstrated that dietary inclusion of citric acid with phytase as supplement enhance growth by reducing the pH in the gut which increases the phytate hydrolysis, kills the pathogens, decreases the rate of gastric emptying, improves mineralization and nutrient absorption.

In this study, commercial parents and synthetic parents which were developed from commercial maternal and paternal lines are compared. During the study, a total of 19654 animals, as being 8520 female, 1275 male chicks from commercial line (TK) and 8584 female, 1275 male chicks from synthetic line (SH), were used. Broiler experiment was conducted with a total of mixed-sex 2073 chicks, as being 1044 (3x348) chicks from TK group and 1029 (3x343) chicks from SH group. In 23 weeks growing period, female parents from TK and SH groups consumed 9.91 and 9.87 kg feed per animal, completed the process with 6.5% and 7.3% mortality and separation rate, 87% and 85% uniformity and lastly, 2846 and 2753g live weights at the end of 23 weeks, respectively. In the meantime, male parents with 9.5% and 10.8% mortality and separation rate consumed 11.1 and 11.3 kg feed per animal, respectively. Female parents from TK and SH groups reached 5% egg production efficiency at the ages of 26 and 25 weeks, and peak production at the ages of 35 and 32 weeks, respectively. At the age of 50 weeks, 5.7% and 6.0% mortality and separation rate, 84.5% and 83.8% peak egg production efficiency, 129.0 and 128.0 pcs of egg production, 116.8 and 118.5 pcs of incubating egg production, 62.5 and 60.0g of average incubating egg weight, 82.1% and 80.6% incubation yield were observed in the parents from TK and SH groups, respectively. Broiler chicks, with the weight of 39.7 and 37.7 g, obtained from TK and SH parents respectively reached the live weight of 2481 and 2375 g at the 42nd day consuming 4429 and 4372 g feed, respectively. In this broiler experiment, the feed conversion ratio was determined as 1.79 and 1.80 respectively. In the study, it was concluded, that new synthetic line obtained from commercial maternal and paternal lines can be used for broiler production.

Labeo rohita and Cirrhinus mrigala are the two Indian major carps and chief components of polyculture system in the local population. Proximate body composition is the analysis of water, fat, protein and ash contents of fish. Values are vary considerably within and between species, size, sexual condition, feeding season and physical activity. The percentage of water is a good indicator of its relative contents of energy, proteins and lipids. Determination of some proximate profiles such as protein content, lipid, ash and other nutrients is often necessary to ensure that they are within the range of dietary requirement and commercial specifications. Based on this background the present study was aimed to evaluate the nutritional value of some major craps (Labeo rohita and Cirrhinus mrigala) fishes of Peshawar Carp Hatchery and training centre Sherabad. The proximate composition of Labeo rohita and Cirrhinus mrigala samples were determined and data was evaluated statistically by performing t-test through Sigma Plot and graphs were made by using Graph Pad Prism. The average value of crude protein for Cirrhinus mrigala was found higher than Labeo rohita (51.7% and 39.04%) similarly the water contents were also found higher in Cirrhinus mrigala than Labeo rohita (75.88% and 73.95%). The average value of dry matter and muscle fats contents were lowered in Cirrhinus mrigala than Labeo rohita (24.11% and 26.04%) and (13.00% and 13.45%) respectively. However, the ash contents were similar in both of experimental species (23.91% and 23.93%). From these results, it is concluded that both Cirrhinus mrigala than Labeo rohita are very proteineous and have low fats contents so it is very good for the health of consumers. Further research is recommended on the other parameters and miss rays of this work.

In this study, it was aimed to determine the concentrations of some elements in sediment along depht profile in core collected at the Lake Hazar (Elazıg) and to compared the results according to recent geological periods. For this purpose, the levels of arsenic (As), mercury (Hg), molybdenum (Mo), barium (Ba), uranium (U), tin (Sn), titanium (Ti), lanthanum (La) and beryllium (Be) on every 5 cm of the piston core samples taken as part of a TUBİTAK project (No: 111Y045) from Lake Hazar were detected. The lowest concentrations of Ba, Hg, La, Ti and U were found (111 ppm, 0.01 ppm, 4.4 ppm, 1190 ppm and 0.6 ppm respectively) at 81-83 cm in depth. It was determined that it belonged to 10 000 B.P. and to Holocene Period (10.5 thousand B.P.). The highest concentrations of As, Ba, Hg, Sn, La, Mo, Ti and U were found different depth in the core in Lake Hazar. The highest concentrations of Hg in the core were detected between 4-6 cm that this depth was determined corresponds to present day. The highest levels of As and Ba found that it belonged to Pre-Glacial Period/ Late Pleistocene Period (10.5 thousand B.P.). The highest concentration of other elements (Sn, La, Mo and Ti) determined that it belonged to Last Glacial Maximum Period/Late Pleistocene Period (between 23-16 thousand B.P.). The geological structure of the basin where the lake ecosystem is located, biological and hydrological processes, climatic and anthropogenic factors can be cited as the reasons for these differences.

Vegetables; in terms of vitamins, nutritional fiber, phenolic component and mineral matter has an important role in human nutrition. There are many species of purple-red vegetables, some of which are well-known, such as red beet (Beta vulgaris), black carrot (Daucus carota ssp. sativus var. atrorubens Alef), black radish (Raphanus sativus L. var. niger), purple cabbage (Brassica oleracea L. var. capitata f. rubra). Purple or red vegetables have higher antioxidant potential compared to other vegetables, which have many beneficial properties such as antimicrobial, antifungal, anti-inflammatory and liver protection. Each of vegetables which is black carrot, beetroot, black radish and purple cabbage contains p-coumaric acid, betaxanthin, ellagic acid and indole-3-carbinol respectively. In this study, Antifungal effect of ethanol extracts obtained from red beet, black carrot, black radish which are inner and peel part, purple cabbage against 7 different subspecies of Penicillium, 6 different subspecies of Aspergillus and Mucor racemosus, Botrytis cinerea, Geotrichum candidum, Cladosporium claudosporioides, Rhizopus nigricans species were determined by using disk diffusion method. As a consequence; it was determined that 7 different samples had antifungal effect on 18 different mold species at various rate. The highest antifungal effect was observed with 23.05±0.05 mm zone diameter against A. fumigatus in black radish inner part ethanol extract. This value was pursued by red beet inner part ethanol extract against M. racemosus with 21.44±0.12 mm zone diameter. It was concluded that the lowest antifungal effect on mold species except for P. citrinum, P. solitum and B. cinerea in purple cabbage extract.

In this study, various extracts of Hypericum perforatum L. were investigated in terms of their extraction yields. For this purpose, five solvent systems including 70%EtOH-30% H2O (A), 50%EtOH-50% H2O (B), 30%EtOH-70% H2O (C), 100% EtOH (D), and 100% H2O (E) were used. Ultrasonic-assisted extraction was used for extraction and extraction processes were performed at different temperatures (30°-70oC) and extraction times (30-70 min.). The optimum extraction conditions for H. perforatum was determined based on extraction yield, total phenolic contents, and DPPH radical scavenging activities of the crude extracts, as well. The best ultrasound extraction conditions are achieved in the presence of 70%EtOH-30% H2O solvent system, for 40 min, at 30°C for H. perforatum.
