Engin Özgöz | Ebubekir Altuntas | Abdullah Kasap
In this study, it was aimed to evaluate of the quality of the sowing process applied by 10 different producers in their fields in Tokat / Kazova, in the cultivation of grain corn, by Statistical Process Control. In determining of the quality of the sowing process, plant spacing uniformity, seeding depth uniformity and ratio of plant emergence were used. Acceptable plant spacing, the multiples ratio and the miss ratio were determined for planting spacing uniformity on the row. Plant emergence ratio values varied between 59.60% (D field) and 93.13% (B field) in the trial areas. Acceptable plant spacing, the multiples ratio and the miss ratio values ranged from 65.56% - 90.24%, 4.02 - 15.69% and 5.11% - 12.91%, in the trial areas, respectively. It was concluded that the sowing process is generally ‘Moderate’ and ‘Inadequate’ according to the parameters of plant spacing uniformity. Similarly, individual and moving range quality charts prepared for statistical quality control of plant spacing uniformity and seeding depth uniformity showed that the sowing process was not under control. According to these results, it is necessary to take precautions regarding the factors that negatively affect the quality of the sowing process for sustainable agricultural production.

In this study, the effects of light stimulation at normal (NLS: 154 days) and early (ELS: 140 days) age on some physiological and reproductive traits in dam and sire broiler pure-lines were carried out during the laying period. The study was conducted with A1, A2, A3, A4 dam lines and B1, B2 sire lines up to 43 weeks of age, whose breeding studies were carried out in Eskişehir Geçit Kuşağı Agricultural Research Institute. Live weight and feed consumption were determined during the growing period. In the laying period, in addition to these, the first laying age, 50% yield age, egg yield, hatching egg yield and egg weight were determined. The data obtained were evaluated according to light stimulation age and pure-lines by two factor analysis of variance. NLS and ELS treatments did not significantly affect the body weights of the pure-lines at 20, 24 and 43 weeks of age. However, differences were found significant in terms of body weight at 20, 24 and 43 weeks of age in pure-lines. Lines reached the first laying age at 172 days in NLS, and at 165 days of age in ELS. The 50% yield age was realized at 184 d and 176 d of age in parallel with the first laying age. The effects of light stimulation age on egg yield and hatching egg yield were found significant. In NLS treatment all pure-lines, 5 more eggs were produced in egg yield and hatching egg yield. However, differences in egg yield and weight in pure-lines were found significant. The study results showed that the egg production can be increased by first light stimulation at the 20 weeks of age, provided that at least 2 kg live weight is achieved in broiler pure-lines.

2020
Hür Can Tümay | Ayhan Filazi
Although the studies on ear, nose and throat (ENT) diseases and treatment methods are high in human medicine, they are rarely performed and neglected in veterinary medicine. Antibiotics are generally preferred for ENT diseases in animals. However, there is an increase in infections from microorganisms that develop multiple antibiotic resistance due to overuse and misuse of antibiotics. Another group of drugs used in ENT diseases are antiseptics. Bacterial resistance to agents used as antiseptics is more limited than antibiotics. Studies on the use of substances with antiseptic properties in the treatment of ENT disorders in animals have been limited. Even though these substances are used empirically in the field, there are no studies in the literature examining the effects of these substances on ENT. In this review, the properties of antiseptic substances recommended for use in the field and in the literature for ENT diseases of animals are discussed.

Tayfun Çukur | Nuray Kızılaslan | Figen Çukur | Halil Kızılaslan
Undoubtedly, supply demand balance must be ensured for the development of geographically indications products. In order to increase the demand for geographically indications products, firstly, consumers should be aware of the geographically indications products and have information about the benefits and advantages of these products. Undoubtedly, as with other agricultural products, price is also an important issue for purchases in geographical indications products. Therefore, it was aimed to determine the factors affecting consumers' willingness to pay for geographical indications products in the Tokat province. For this purpose, face to face survey was conducted with 382 consumers. It was determined that 49,21% of the consumers who participated in the research wanted to pay more price for a product with a geographical indications label. According to the results of the probit analysis, a positive relation was found between awering that Niksar walnut is a geographical indications product and the willingness to pay for geographical indications products. However, a negative correlation was found between monthly food expenditure and tendency to pay for geographical indications products.

Azim Şimşek
The aim of this study was to investigate the effects of different cooking techniques and internal cooking temperature applications on the oxidative stability of hamburger patties. For this purpose, 4 different cooking techniques (boiling, oven-roasting, grilling and microwave) and 2 different internal cooking temperatures (72°C and 78°C) were used. Microwave cooking caused the highest cooking loss values. The higher cooking loss values were determined as a result of the 78°C internal cooking temperature application. Lower pH values were obtained by microwave cooking. Boiling increased L* and a* values, whereas decreased b* values compared to other cooking techniques. While a* values decreased with storage in hamburger patties, b* and HUE angle values increased. The lower thiobarbituric acid reactive substances (TBARS) and lipid hydroperoxide (LPO) values were determined in samples cooked with microwave or boiling technique. Even though there was no TBARS difference between different internal cooking temperature applications, the higher LPO values were determined in the application of 78°C internal cooking temperature. The results of this study showed that less oxidative changes could be occurred by the use of either microwave or boiling technique in hamburger patty production.

Murad Mohammed Baker | Beyan Ahmed Yuya
Ethiopia’s sesame export earn percentage share in the total export had been rapid declining over the last decades while it was the second commodity in currency grossing of the country. The objective of this study was to examine the determinant factors of Ethiopia’s sesame exports performance, in the aspect of export trade, by the use of a more realistic model approach, a panel gravity model. It used short panel data that cover 11 countries of consistent Ethiopia’s sesame importers for the period of 13 years from 2002 to 2014. The panel unit root test of Levin-Lin-Chu was used for each variable and applied the first difference transformation for the variables that had a unit root. The random effect model results suggested that real gross domestic product of importing countries; Ethiopian real gross domestic product, real exchange rate and weighted distance were found to be the determinant factors of Ethiopia’s sesame exports performance. The estimated results revealed that as real gross domestic product of importing countries increase by 1%, the flows of Ethiopia’s sesame exports performance increase by 1.63%. Based on the finding results, the researcher recommends that the policy maker must adopt the policies that reduce the cost of shipping through improving the infrastructure for shipments sector and contract a free trade agreement with distant countries. The government should encourage the private sector to diversify their products and improving the quality of its products to increase the competitiveness the Ethiopian products in foreign markets.

Husbandry has a special importance for people who live in rural areas in terms of agricultural income and profitability due to some contributions such as; providing cash flow throughout the year, product processing, balanced usage of labour force, and risk diversification. According to FAO data of 2017, Turkey’s ratio in the world’s total cattle existence was 0.99%, and it had a 2.78% ratio in total milk production. According to TSI data between 2004 and 2018; the number of total cattle reached 17.042.506 with a ratio increase of 4.62%, and the annual milk production amount reached 20.036.877 tons with a ratio increase of 7.23%. Within the period of time that is mentioned above, the contribution ratio of culture breed cattle in milk production reached 61.39% from 33.63%. However, in terms of milk cow productivity, Turkey is the 57th in the world. The cities of Konya, İzmir, Erzurum, Balıkesir, and Diyarbakır provide 21.74% of Turkey’s total milk cow existence, and 22.77% of the milk production total. In terms of agricultural subsidies which are provided by Ministry of Agriculture and Forestry, husbandry took a share of 25.79% from the 14.5 billion TL total agricultural subsidies in 2018. According to the research results, directly or indirectly, husbandry contributes to decreasing development level differences between regions, and it helps to improve enterprises’ income levels in rural areas.

In this research, some physicochemical and microbiological characteristics and mineral compositions of marmalades produced by traditional method using Berberis integerrima Bunge (purple barberry), Berberis vulgaris L. (pink barberry), Rosa pimpinellifolia L. (black rosehip), Rosa canina L. (pink rosehip), Malus sylvestris Miller (sour apple), and Vaccinium corymbosum L. (blueberry) wild fruit naturally grown in Bayburt and Trabzon provinces were determined. As a result of the research; pH 2.56-4.18, titration acidity (in terms of citric acid) 0.62-3.40%, dry matter 53.65-64.90%, water soluble dry matter 52.28-64.53%, water activity 0.818-0.894 and HMF (5-hydroxymethyl-2-furfural) were detected in the range of 5.81-53.40 mg/kg. As a result of microbiological analysis, total aerobic mesophilic bacteria, coliform group bacteria and yeast-mold were not detected in any of the samples. In the marmalade samples, the macro minerals Ca, K, P and Mg are ranged from 23.56-425.12 mg/kg, 1275.74-5918.10 mg/kg, 21.98-921.26 mg/kg and 125.50-776.23 mg/kg, respectively. Of the micro-minerals Fe 4034.85-22346.74 µg/kg, Mn 531.63-15065.91 µg/kg, Zn 345.40-6250.76 µg/kg, B 2872.99-7300.37 µg/kg, and Ba were found between 689.31-6455.24 µg/kg. The results of heavy metal analysis showed that marmalade samples were within reliable limits. It is concluded that these fruits, which are not usually consumed as table, but have rich mineral composition, characteristic taste and pleasant aroma, can be evaluated in marmalade production. In the years when the yields of wild fruits are high, it can be processed into products with long shelf life such as jam and marmalade and converted into added value can contribute to the regional economy.

Selda Bulca | Fahriye Ümüt | Atakan Koç
In this study, microbial transglutaminase (MTGase) enzyme was used to produce yogurt from camel milk. It was reported that camel milk is rich in antimicrobial substances such as lysozyme, lactoperoxidase, lactoferrin and immunoglobulins, which prevent the production of yogurt from camel milk. With the advances in enzymology, it has been suggested that using enzymatic modifications to improve the functional properties and nutritional value of proteins may be effective in the production of yogurt from camel milk. For this purpose, the protein content of camel milk was increased by 6.2% with the addition of sodium caseinate, whey protein concentrate and micellar casein powder. MTGase enzyme was used at concentrations of 3 U and 6 U and the enzyme and the starter culture were added into the camel milk at the same time after that it was left for fermentation. Viscosity, pH and titratable acidity (as lactic acid, %) analyses were performed every hour during fermentation. The increase in viscosity formed as a result of cross-linking with the addition of MTGase enzyme, and the cross-linking formed were determined by decreasing the monomer band intensity of protein fractions with SDS-PAGE. It was found that the higher the MTGase concentration the higher the crosslinking reactions between the amino acids and the higher was the relative viscosity. In addition, the number of yogurt bacteria was determined on both M17 agar and MRS agar to investigate whether yogurt bacteria grow in camel milk and whether their growth is affected by the MTGase enzyme. As a result of the analysis, it was determined that the addition of MTGase enzyme has no suppressive effect on the growth of bacteria.

In addition to the good adaptation of high temperatures and poor soils, cowpea (Vigna unguiculata L.) can be a good source of forage for livestock. This study was carried out to determine seed yield and some agronomical parameters of cowpea grown in different row spaces as double crop in Samsun ecological conditions. In the experiment, forage cowpea cultivar Ulkem and Line H-8 grown in four row spaces (20, 35, 50, 65 cm) in a Randomized Split Block Design with three replications. Seeds were sowed after harvesting wheat at July 13, 2017 and 15 July 2018. Seed harvest was made at October 20, 2017 and November 5, 2018. The results showed that seed yields ranged from 765 to 2178 kg ha-1 in 2017 and 397 to 1464 kg ha-1 in 2018. 1000 seed weight ranged from 161.17 to 183.93 g in 2017 and 146.40 to 160.90 g in 2018. In 2017 and 2018, mature pod ratio were 65.7 – 85.8, 30.0 – 60.3% respectively. Pod number per plant was between 5.66-15.00 pods/plant in 2017, 9.50-16.25 pods/plant in 2018. Seed number per pod was ranged from 8.80 to 12.43 seeds/pod in 2017, from 8.00 to 11.50 seeds/pod in 2018. Though the highest seed yields were obtained from 20 cm row space, it is risky cultivated cowpea for seed production as double crop in Samsun conditions because of earlier autumn rainfall and high humidity.
