Pollinators play vital roles to the environment, biodiversity conservation, food security and several dimensions of global sustainable development. Honey bee is an important pollinator globally but has been exposed to increasing threats from diseases, pesticides and biotic stresses. This review paper highlights the role of honey bees as pollinators, addresses threats which influence decline of honey bees and assess pesticidal risk toxicity on non-target organisms. Decline of honey bee population is caused by several factors including habitat fragmentation, pesticidal toxicity, colony collapse disorder and climate change. Pesticidal residue and toxicity has an adverse effect which results in honey bee population decline, disturb foraging and contamination of bee products. Residues of agricultural pesticides like pyrethroid and neonicotinoid pose a serious threat on honey bee health further reducing agricultural production and diversity. Pesticidal risk assessments are carried out to study effects of pesticides on pollinators with an aim to provide measures to safeguard their abundance, diversity and health. Sustainable agriculture, effective policy and proper management can decrease pollinators' risk by helping to diversify the agriculture for pollen and nectars with reduced usage of pesticides and proper management.

The aim of this study was to determine the effect of housing system on morphological characteristics of Atak-S cocks reared in closed and free range systems. Cocks were fed with standard feed according to feeding program for seventeen weeks. In order to determine the effect of the housing system on some morphological features and asymmetry, Crest length (İU), Crest width (İG), Eye width (GG), Nose length (BU), Face width (YG), Wattle length (SU), Beak length (GU) in bilateral features, measurements were made from the right and left sides on the head of the cocks. Furthermore, foot features such as Width of tarsometatarsus at the joint with tibiotarsus (EG), Length of tarsometatarsus (TU), Width at 1 cm above the spur of tarsometatarsus (MG1), Width of tarsometatarsus at the spur (MG2), Length of the back toe (AP), Length of the outer toe nail (DT), Length of the fourth phalanx of the outer toe (D4), Length of the third phalanx of the outer toe (D3), Length of the mid toe nail (OT), Length of the fourth phalanx of the mid toe (O4), Length of the third phalanx of the mid toe (O3) measurements were taken on the right and left feet of the cocks. All measurements were made in millimetres (0.01 mm) using a digital caliper. Relative asymmetry (GA) and fluctuating asymmetry (DA) values were calculated for the features showing bilateral symmetry. According to the statistical analysis on the obtained data, the morphological characteristics of ATAK-S cocks were not affected by the housing system, and that the characters underlined in both housing conditions developed in the same way as right and left.

Bu çalışma yumurtacı tavuk rasyonlarına farklı seviyelerde kaplamalı sodyum bütirat ilavesinin performans, yumurta kalitesi ve bazı kan parametreleri üzerine etkisini belirlemek amacıyla yürütülmüştür. Çalışmada, 60 haftalık yaşta, toplam 72 adet yumurta tavuğu, 56 gün süreyle, kontrol ve sodyum bütiratın farklı seviyelerinin ilavesiyle (300, 600 ve 1200 mg/kg) oluşturulan rasyonlarla beslenmişlerdir. Çalışma 6 tekerrürlü olarak, 4 muamele grubunda yürütülmüştür. Deneme sonucunda muamele gruplarının, canlı ağırlık değişimi, yumurta verimi, yem tüketimi, yem değerlendirme katsayısı, yumurta ağırlığı ve yumurta kitlesi üzerine etkisi önemsiz olmuştur. Yumurta tavuğu rasyonlarına sodyum bütirat ilavesi, yumurta kabuk kırılma direnci, yumurta kabuk oranı ve kabuk kalınlığı, yumurta şekil indeksi, ak ve sarı indeksi, hasarlı yumurta oranı ile L*, a* ve b* yumurta sarısı renk kriterleri üzerine etkisi önemsiz olmuştur. Serum parametrelerinden kolesterol, HDL, albümin, Ca ve P düzeyleri bakımından muamele grupları arasında önemli bir fark olmaz iken serum globulin, total protein ve ürik asit seviyeleri bakımından görülen farklılıklar önemli olmuştur. Deneme sonuçlarına göre, 60 haftalık yaştaki yumurta tavuklarında performans ve yumurta kalitesinin iyileştirilmesinde rasyona sodyum bütiratın ilavesine gerek olmadığı sonucuna varılmıştır.

With this study, it is aimed to reveal the effect of economically sustainable dairy goat breeding in order to provide sufficient income. For this purpose, in Çanakkale Province, which has 234.408 thousand head goats, mostly dairy goat breeding, 30 enterprises were selected through proportional sampling to determine the herd size for technical herd analysis and economic sustainability in family subsistence. The parameters obtained are milk yield (2.1 L), herd size (168.21 heads), number of animals milked (82.54 heads), milk marketing rate (96.75%). 52.30% of milk production costs are variable costs and 47.70% are fixed costs. Feed costs have the highest share in total production costs with 43.88%. In the enterprises, 68.34% of the total gross production value obtained from goat breeding is milk, 27.06% is Productive Fixture Increase and 4.60% is fertilizer income. The cost of 1 L milk in the enterprises was calculated as 1.73 TL (USD 0.36), (the average rate of 1 USD in 2018 is 4.81 TL). 1 L of goat milk price is 3 TL (USD 0.62), (Canakkale, Turkey, sales price, 2018) considering; It has been determined that the enterprises make an average profit of 1.27 TL / L per liter (42%). With the calculated parameters, a profit of 602.27 TL (125.21 Dollars) was obtained from only milk sales in a production period from a dairy goat. A family of four the poverty line, according to the Turkey Statistical Institute 2018 poverty study results are reported on a monthly 6609.000 TL. As a result of the research, the average milk yield is 2.10 L, and as a result of the calculation made considering the average milking time of 225 days and the profit obtained from it, the number of milky goats that will meet the poverty line for a family of four was determined as 131 heads.

In this study, optimum harvest times, cluster and berry characteristics of four grape cultivars (Hasandede, Öküzgözü, Boğazkere, and HorozKarası) grown in Mecitözü (Çorum) ecological conditions were determined. In two consecutive years (2017-2018) yield, clusters, berry properties, water-soluble solid content, pH, titratable acidity, maturity index properties were determined. Some biochemical changes in grape varieties were followed during the ripening periods in the second year. The highest yield in both years was obtained from the variety of Horoz Karası (1421.2 and 1504.8 kg/da), while the lowest yield was obtained from Öküzgözü (619.4 and 578.31 kg/da). During the harvest period, the total acidity and pH values must be changed according to years and varieties. The total soluble solids (TSS) and pH values increased with maturation, whereas the total acidity was found to decrease till the last observation date. During the harvest period, all varieties reached optimum harvest maturity in both years.

The most important way to reduce feed inputs is to increase the amount of good quality roughage. According to official data of Turkey Statistical Institute (TSI) in 2018, Turkey has 18.6 million bovine animal unit (BAU) livestock existence, and 85 million tons of quality roughage is needed to feed the animal existence. However, total quality roughage production of in the Turkey is 59 million, 10 million from meadow and grassland lands, 18 million from forage crops, 31 million from plant residues. Accordingly, the roughage gap in the country is 26 million tons, this accounts for 30% of the need. The quality roughage deficit is quite above this. The Eastern Anatolia region and Muş province have a great potential in Turkey’s animal husbandry both in terms of the presence of animals and the productivity of the grassland areas. The amount of forage crops produced in the region, where livestock is based on pasture and grassland in general, is also above the average of forage crops produced in Turkey. In order to closure roughage gap in Turkey, it is necessary to obtain higher yields from these areas by improvement and using them in accordance with the technique of those areas. In addition, it is necessary to increase the cultivation areas of forage crops within the field agriculture. By the closure of the shortage of roughage, higher animal production will be achieved, input costs may decrease, and the income level of animal producers will increase and the price of animal products may decrease. The research in Turkey, Eastern Anatolia Region and Mus Province of grassland and forage crops status, deficit and status of roughage, issues were analyzed.

In this study, it was aimed to evaluate the effects of adding olive seed powder (OSP) and eggshell powder (ESP) to whole wheat biscuit formulation on some of the physico-chemical, chemical, textural and sensory properties. Incorporation of powder materials was done by adding to biscuit dough at prespecified concentrations of OSP (7.5% and 15%) and ESP (2.5%) based on total wheat flour. The data obtained from this study revealed that fortification with powder materials affected protein and moisture content of final product. Additionally, adding powder materials to whole wheat biscuit formulation increased the total amount of phenolics and antioxidant activity significantly. Results of instrumental colour analysis indicated that fortification increased darkness and redness when compared with the control. Sensory analysis data indicated that non-fortified and fortified samples provided similar sensory attributes.

Medicinal plants are important natural materials used in the treatment of many diseases. In this study, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of endemic Salvia absconditiflora Greuter & Burdet were determined. Plant samples were collected from Nigde and Erzincan (Turkey) provinces. Ethanol (EtOH) extracts of plant samples were extracted. TAS, TOS and OSI values were determined using Rel Assay Diagnostics kits. As a result of the studies, it has been determined that the samples of the plant collected from Nigde have higher TAS, TOS and OSI values. As a result, it has been determined that S. absconditiflora can be used as a potential antioxidant source due to high TAS values.
