With this research, it was aimed to investigate the content of some heavy metals (Cu, Zn, Fe, Mn) and macro minerals (Mg, Ca, K, Na) in the water resources that meet the water needs of livestock in Iğdır. Water samples were collected from natural springs, surface waters, wells and drilling waters, Aras river and its branches in the region. The data obtained were classified in two different ways and statistical analysis was performed. 1. According to the districts; Central District, Tuzluca, Karakoyunlu, Aralık. 2. According to the type of water resources; Ağrı Mountain spring waters, Ağrı Mountain surface waters, Mountain spring waters, Mountain surface waters, west of Aras river and it’s canals, east of Aras river, Well and Drilling waters. Mineral levels of the water samples were measured by using Atomic Absorption Spectrometer with flame system. According to the district assessment, it was seen that Tuzluca district had lower values compared to other districts. When evaluated according to the type of water source, water mineral content was determined to increase as the waters flowing forward on the surface after reaching to the earth surface It was even found to have become unfit for consumption towards the end. Consequently, with this research, the levels of some heavy metals and macro minerals in the waters used for livestock in the Iğdır region were revealed for the first time with their details. Except for the waters of the East Aras river, the waters of the Iğdır region were found to be of usable quality for animal husbandry.

The present study aimed to evaluate the activation characteristics of the leaping mullet spermatozoa and diluted with four different media (D1, D2, D3, D4) for 250 h at 4±2°C. The semen was collected from nine wild fish in Homa Lagoon, İzmir, Turkey in July, during reproductive season. In each trial (n = 9), semen samples were collected and mixed to reduce sperm quality variation to obtain the required gametes for the experiment. The semen was activated with natural seawater (salinity of 34, pH 7.9 and 4±2°C) to determine: motility time, motility rate and viability of sperm. Dilution with inactivation media 1:3 increased motility time of diluted semen than control group. At the end of the experiment, no significant difference was found for the duration of survival in the D2 and D4 groups. The highest survival rate was found in D2 group.

This study was conducted to compare the internal and external quality characteristics of the eggs of Atak-S laying hybrids kept in enriched cage and free-range rearing systems. In the study; 400 Atak-S hybrids, 31 weeks of age were fed for 6 weeks of experimental period. Throughout the experiment, with weekly intervals, 15 eggs of each group were collected from the laying hens kept in both systems for determination of the quality of the exterior (egg shape index and egg shell thickness) and interior (albumen and yolk width, height, yolk height and yolk colour). At the end of the experiment, there were statistically significant differences between groups for Haugh unit (wk. 2), albumen index (wk. 6), egg shell rate (wk. 1, 2, 3), egg shell thickness (wk. 6), yolk colour for L (wk. 3) and for a (wk. 1, 3). However, there were no significant differences between groups for other weeks and mean values, egg weight, shape index and yolk index.

In the study, Trachurus trachurus, Engraulis encrasicolus, Merlangius merlangius euxinus, and Mullus barbatus from along the coast of Sinop were analysed for the content of copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), iron (Fe), nickel (Ni) and aluminium (Al) in the muscle. Zn, Pb and Cd concentrations were determined to be lightly higher than the acceptable rates in fish samples. The provisional tolerable daily and weekly intake of trace metals in our work were all under than the limits set by the Food and Agriculture Organization/World Health Organization, while for Cd, only M. barbatus was higher than FAO limits. E. encrasicolus and M. barbatus had the highest values for the collected total target danger section, but they did not posture a potential hazard within the diet of local residents. For carcinogenic and non carcinogenic risk assessment, the results were lower than the admissible rate of EPA. In the four fish species in the work, the Target cancer risk values of Ni were greater than 10-4, whereas the Target cancer risk values of Pb were smaller than 10-6. According to these results, it is thought that the Ni concentration in fish does pose a carcinogenic risk due to long-term and continuous consumption.

To improve the reproductive performance; several scholars conducted research in different parts of Ethiopia on indigenous, crosses and exotic chickens. However, there were inconsistencies among the various studies. This review was, therefore, conducted to assess the reproductive characteristics of indigenous, exotic and their crosses. Under scavenging system, the indigenous chickens are characterized by less clutch size (2.7-4.2 per year), good hatchability rate (59.6-93.2%), higher mortality rates (25.3-61.15), and reach sexual maturity at advanced age (19.6-26.8 weeks for male; 19.7-34.05 weeks for female). The age at first mating and laying recorded for exotic and their crossbreeds were nearly similar to those of indigenous chickens. The hatchability rate of crossbreed chickens are varying from 54.7-78.7% and it is by far lower for exotic breeds. The exotic (18.83-53%) and crossbreed (9-40%) chickens are relatively better in survival rate than local chickens. Overall, the local chickens are better for their hatchability and have reproduction performance than exotic and crossbreed chickens. From this review, it is concluded that there is variation in chicken reproductive performance of the same breed in different parts of the country.

There are many natural growth area in Turkey and utilizability is increasingly in different areas. Berry fruits involve several species such as grape (Vitis spp.), currant (Ribes spp.), rosehip (Rosa spp.), strawberry (Fragaria spp.), raspberry (Rubus spp.), pomegranate (Punica spp.), blackberry (Rubus spp.), bilberry (Vaccinium spp.), mulberry (Morus spp.) and cornelian cherry (Cornus spp.). Berries are soft fruits that turn from red to blue or black. They contain a good source of vitamins and minerals, and they have various phytochemical compositions that relevant to consumer health. Different varieties of berries contain quite variable concentrations of ascorbic acid, folic acid, anthocyanin, flavonol, ellagitannins and many diversity of hydroxybenzoic acid. Berries have antioxidant, antimicrobial, antifungal and anticarcinogenic properties due to rich content of phytochemical. In this study, Antifungal effect of ethanol extracts obtained from strawberry, raspberry, pomegranate, blackberry, bilberry, mulberry and cornelian cherry 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 result of the research; It was determined that 9 different samples had antifungal effect on 18 different mold species at various rate. The highest antifungal effect was observed with 24.65 milimeter zone diameter against Mucor racemosus in pomegranate peel extract. This value was followed by blackberry extract against Penicillium glaucum and Penicillium chrysogenum with 20.54 and 20.03 milimeter zone diameter, respectively. It was concluded that the lowest antifungal effect on mold species apart from Aspergillus flavus in blue bilberry extract.

To meet the nutritional requirements required for human and animal nutrition due to climatic changes, research on determination of rich in nutrients and quality, products with high resistance to adverse environmental conditions and their possibilities for growing and reproduction are carried out. This research was carried out between 2018-2019. As a material, seeds belonging to the amaranth (Amarantus mantegazzianus), chia (Salvia hispanica L.), quinoa (Chenopodium quinoa) and teff (Eragrostis tef [Zucc] Trotter) plants were studied. Some characteristics of these seeds were determined such as shape, size, mean arithmetic and geometric diameter, sphericity and thousand grain weight. According to the data obtained; the highest average length (1.140 mm), width (1.080 mm) and surface area (0.930 mm2) of the seeds of the quinoa seeds compared to other seeds; the tambourine seeds had the lowest average length (0.540 mm), width (0.300 mm) and surface area (0.130 mm2) values. In terms of thousand grain weights, the seeds of the quinoa plant are the heaviest seeds with 3.3600 g; the lightest seeds were determined to belong to the tambourine seeds with 0.0028 g.

Fermented milk is known as a major functional food that has proven health benefits, such as probiotic effects. The fermented milk, laban, is the foremost dairy product in Yemen. This study aimed to evaluate the nutritional and health-promoting properties and antioxidant activity of laban. Nutritional and health-promoting properties were estimated. Antioxidant activity was evaluated by measuring total polyphenol levels, 1.1-diphenyl-2-picrylhydrazyl scavenging activity, reducing power, and total antioxidant capacity. The antioxidant activity of a laban-Pulicaria jaubertii mixture was also determined. Results showed considerable quantities of nutrients, especially fats, in both milk and laban. The composition differences between milk and laban show several significant health-promoting properties for laban. Laban showed higher antioxidant activity than raw milk and the addition of P. jaubertii to the laban, increased antioxidant activity. The properties of laban suggested the potential use of laban as a promising functional food with excellent health benefits, especially when mixed with P. jaubertii.

The study investigated the metal levels in biotic and abiotic materials from Giresun forests. While soil and water samples were selected as abiotic materials, leaves and moss were selected as biotic materials in forest. These selected materials were sampled from six stations. All samples were analyzed three times for arsenic, iron, chromium, copper, manganese, nickel, lead and zinc by ICP-OES. A logarithmic transformation was done on the data to improve normality. One way ANOVA and Duncan’s multiple range tests were performed to test the differences among metal levels of stations. The differences among metal levels in stations were statistically significant (p

In this study, fertility and milk yield characteristics of Simmental (SIM) and Red-Holstein (RH) cattle raised in a private dairy farm in Aydın province were determined. For fertility traits, days open (DO), calving interval (CI), gestation length (GL) and number of inseminations per pregnancy (NIPP), for milk yield traits lactation length (LL), lactation milk yield (LMY), 305-days milk yield (305-dMY), peak time (PT) and peak milk yield (PMY) were determined. The means of DO, CI, GL and NIPP of RH and SIM breeds were 109.44±5.66 d and 96.06±3.51 d, 389.16±5.70 d and 380.37±3.54 d, 279.71±0.469 d and 284.94±0.303 d, 1.88±0.099 and 1.85±0.065; the means of LL, LMY, 305-dMY, PT and PMY were 333.00±5.405 d and 322.72±3.233 d, 8235.32±148.099 kg and 7357.03±88.122 kg, 7628.78±109.148 kg and 6938.09±64.945 kg, 46.55±2.196 d and 44.46±1.218 d, and 34.68±0.567 kg and 31.47±0.314 kg, respectively. Although, significant fertility and milk yield differences were obtained between the breeds, the favorable performances of both SIM and RH breeds in terms of all features, considered as the environmental factors such as management-feeding-housing-herd management provided to animals in the farm were also suitable.
