Yusuf Ziya Oğrak | Abdullah Özbilgin | Recep Gümüş | Milivoje Uroševıć
Bu çalışma, Japon Bıldırcınlarının (Coturnix coturnix japonica) beyaz ve kahverengi iki farklı varyetesinde, bazı zoometrik ölçümler ve canlı ağırlıkların, karşılaştırmalı olarak belirlenmesi amacıyla yapılmıştır. Bunun için aynı beslenme ve çevre şartlarında barındırılan, beyaz ve kahverengi varyetelerinden 30'ar (15 erkek, 15 dişi), toplam 60 adet, altı haftalık yaştaki bıldırcında, canlı ağırlıklar ve on iki farklı vücut ölçümüne ait değişkenler değerlendirilmiştir. Altı haftalık yaştaki ortalama canlı ağırlıklar açısından literatür bildirimlerinin birçoğuna göre daha yüksek değerler elde edilmekle birlikte bu çalışmada karşılaştırılan iki renk varyetesi açısından herhangi bir fark görülmezken, dişiler erkeklerden istatistiki olarak anlamlı olacak şekilde daha ağır bulunmuştur. İstatistiki anlamlılıkların elde edildiği zoometrik ölçümlerden kafa genişliği, gaga uzunluğu, gaga genişliği, sternum uzunluğu, bacak uzunluğu ve kanat uzunluğu açısından beyaz bıldırcınlar kahverengi olanlardan daha yüksek değerlere sahip olurken cinsiyete göre ise canlı ağırlık, vücut uzunluğu, göğüs çevresi ve tarsus çevresi değişkenlerinde dişiler daha yüksek değerler almışlardır. Altı haftalık yaştaki Japon bıldırcınlarının canlı ağırlıkları ile kafatası uzunluğu, beden uzunluğu, sternum uzunluğu, orta parmak uzunluğu, kanat uzunluğu, göğüs çevresi ve tarsus çapı değişkenleri arasında pozitif korelasyonlar tespit edilmiştir. Bıldırcın yetiştiriciliğinin yaygınlaşması için tüketiminin artması gerçeği göz önüne alındığında, insanların beslenmede bıldırcınları tercih etmelerini sağlayacak unsurlar üzerinde daha kapsamlı çalışmaların yapılması önerilebilir.

Bu çalışmada, 2017 yılından 2021'e kadar beş generasyon boyunca ıslah ve seleksiyonu sürdürülen Anadolu-T etlik piliç saf hatlarının gelişme ve karkas özelliklerinin ticari hibritle karşılaştırmalı olarak ortaya koyulması amaçlanmıştır. Her generasyonda seleksiyon işleminden sonra yeterli sayıda saf hat (A1, A2, A3, B1, B2) ve ticari hibrit (Ross-308) yumurtaları kuluçka edilerek her genotipten 120 dişi-erkek civciv üretilmiştir. Etlik piliçler 6 hafta süreyle etlik piliç üretim standartlarında yetiştirilmiş ve bu süre sonunda kesim ve karkas özellikleri belirlenmiştir. Gelişme özellikleri olarak canlı ağırlık (CA), yemden yararlanma oranı (YYO) ve yaşama gücü; karkas özellikleri olarak göğüs ve but eti oranı ele alınmıştır. Beş generasyon boyunca 6 haftalık yaşta en yüksek ortalama CA ve en iyi YYO Ross-308 ticari hibritlerde (CA: 2961,2 ile 3481,2 g ve YYO: 1,43 ile 1,60 arasında) elde edilmiştir ve bunu sırasıyla baba (CA: 2633,8 ile 3180,2 g ve YYO: 1,65 ile 1,77 arasında) ve ana hatları (CA: 2307,7 ile 2698,5 g ve YYO: 1,65 ile 1,78 arasında) izlemiştir. Saf hatların yaşama gücü generasyonlara bağlı sayısal farklılıklar gösterse de ticari hibritle genel olarak benzer (%96-100) gerçekleşmiştir. Hem ana hem de baba hatların göğüs oranı ticari hibrite göre daha düşük iken, saf hatlarda but oranının daha yüksek olduğu belirlenmiştir. Saf hatların beş generasyonluk kısa bir seleksiyon geçmişine sahip olması henüz yeterli bir değerlendirmeye imkân vermemektedir. Ana ve baba hatlarında bireysel yemden yararlanma testine ek olarak baba hatlarında canlı ağırlık ve göğüs alanı özelliklerinin de seleksiyon kriteri olarak kullanılmasının canlı ağırlık ve yemden yararlanmayı iyileştirmesi beklenmektedir.

Sagar Bhandari | Pankaj Kumar Yadav | Sramika Rijal
Food security is one of the major global challenges of the twenty-first century. World population is expected to increase by one-third, between 2009 and 2050, and in Asia, crop yield is estimated to decline by 5 to 30% from 2050 onwards compared to 1990. It is high time to seek alternatives that can increase production utilizing existing resources ensuring food security. A home garden can be a viable and sustainable alternative in this regard; nevertheless, it is often neglected. Thus, this study aims to understand the role of the home garden in maintaining household food security and enhancing rural women’s status in Nepal. Two villages of Bishnupur rural municipality, namely, Bajitpur and Musharniya were selected as study sites. 78.6% of households in Bajitpur and 68.4% households in Musharniya were found to have a home garden where crops and livestock were organized in an integrated way. The home garden was found to maintain household food security, ensure food availability for most of the seasons, access of household members to food, its utilization, and stability in production. Furthermore, 66.67% and 58.33% of women sold surplus home garden products in Bajitpur and Musharniya respectively. This signifies the role of home gardening activities in uplifting the social and economic status and, farming knowledge of rural women in both villages. However, there is a lack of extension facilities and subsidies for the home garden to encourage farmers. Therefore, different models of home gardens should be developed and disseminated, prioritizing the integration of the scientific farming system with traditional knowledge for sustainable adoption of the home garden in Nepal.

In this study, an image processing algorithm and classification unit were developed to classify the fruits according to their size and color characteristics. For this purpose, a total of 300 fruits (50 fruit samples from each of the Starkrimson Delicious and Golden Delicious apple varieties, Washington Navel and Valencia Midknight orange varieties, Ekmek and Eşme quince varieties) were used in the experiments. The size and color values measured with a caliper and a spectrophotometer were entered in the developed image processing algorithm to determine the success rates of classifying the fruits. The integration of image processing algorithm with the classification unit classified 88%, 100%, 96%, 82%, 86%, respectively. On the other hand, the size and color values read in fruits with the image processing algorithm were evaluated using predictive techniques used in data mining. For this purpose, K Nearest Neighbor (KNN), Decision Tree (DT), Naive Bayes classification and Multilayer Perceptron Neural Network (MLP) algorithms were used. Algorithms were run with 10-fold cross validation method. In the training of artificial classifiers, the success was 93.6% for KNN, 90.3% for DT, 88.3% for Naive Bayes, 92.6% for MLP and 94.3% for RF.

This study was aimed to evaluate DNA fragmentation by using Comet assay in naturally infected sheep with Anaplasmosis before and after treatment with the Comet method, which shows DNA damage specifically. In the study, blood samples were collected from 10 Anaplosmosis infected and 10 healthy sheep. The anaplosmosis was diagnosed by clinical signs and symptoms. The infection was confirmed by Giemsa staining. The blood was collected from control group and infected group before and after the treatment, from the vena jugularis with the appropriate method. The DNA fragmentation was checked by using the Comet assay of blood cells. The data were analysed throught ANNOVA one-way. The result showed higher DNA fragmentation in sick animals diagnosed with anaplasmosis; tail length and tail moment values were found to be statistically significantly higher than the control group. When the data obtained after imidocarb (IMD) application were compared with obtained during the disease, a decreased DNA damage and tail moment was determined, however, these values higher than control. In this study, DNA damage and the extent of this damage were investigated by the Comet assay method using a healthy control group before and after treatment in animals with Anaplasmosis. When the findings obtained from the study were evaluated, it was seen that Anaplasma agents caused DNA damage and with the imidocarb application given for treatment, DNA damage was reduced and results close to healthy individuals were obtained.

Nutrient elements, one of the major factors shaping plant development, are the major components of plants, and, after being taken from the soil, they are present in different organs of plant at different concentrations. The speciation of nutrient elements within plant body is vital importance for determining the contribution to plant development, knowing the transfer between organs within the body of organs, clearly understanding the factors influencing plant development, and shaping the plant development. In the present study, the change of the concentrations of K and Mg (macronutrient elements) and Cu (micronutrient elements) by species and organ in woody species Prunus cerasifera, Platanus orientalis, Acer negundo, Fraxinus excelsior, Catalpa bignonioides, Aesculus hippocastanum, and Tilia platypyllos. As a result, it was found that the changes of elements by species were statistically significant in all the organs, and, in general, the highest concentrations were observed in leaves. The study results revealed that the concentrations of these elements might significantly vary between the organs in the same species, which varies significantly by the species.

Zeynep Akar | Erza Orhan | Seçil Durmuş
In this study, the antioxidant activity values of infusions at different temperatures of the commercially sold rosehip tea bag. To determine the effect of different infusion temperatures on antioxidant activity, 7 different temperatures (0, 15, 30, 45, 60, 75, 90°C) also including cold infusions temperatures were selected. Infusions of the rosehip tea bags were prepared with packaged drinking water for 5 minutes (recommended time in tea bag packaging) at these temperatures. Antioxidant activity values of the infused extracts were determined by antioxidant activity determination methods: TPC (Total Phenolic Compound), CUPRAC (Cu (II) Ion Reducing Antioxidant Capacity), FRAP (Iron (III) Ion Reducing Antioxidant Power) and ABTS•+ (2.2-azinobis- (3-ethylbenzothiazoline-6-sulphonic acid)) radical scavenging assay. According to the results obtained by the antioxidant determination methods, the highest and lowest activity values for TPC, FRAP and ABTS were measured at 90°C and 0°C, respectively, and a positive correlation was found between temperature and antioxidant activity values. Contrary to the activity values determined in these methods, in the CUPRAC method, the highest and the lowest activity value was measured at 45°C and 90 °C, respectively. As determined in the CUPRAC method, infusions of rosehip tea at low temperatures may provide an advantage in terms of the solubility of some phenolics that can be denatured at high temperatures. In addition, rosehip tea infusions at lower temperatures will contribute to lower energy costs.
