  Investigation of Managerial Practices Related to Calves’ Survival in Dairy Cattle Farms: The Case of Çorum Province

  Bayraktar, Bülent; Tekce, Emre; Aydemir, Seyma; Erdoğan, Yaşar; Aksakal, Vecihi; Ürüsan, Hılal; Kotan, Gökşad Cemil

  This study was conducted using a Cross-Sectional Observational Design to determine the effects of current managerial practices applied in commercial dairy cattle farms in Çorum Province on calf survival. The main material of the study consisted of 120 active farms, which represent the general structure of the dairy cattle sector in the region. Data were collected via face-to-face surveys, and the scale’s reliability was confirmed (Cronbach’s Alpha: 0.742) and suitability for Factor Analysis (KMO: 0.710) was verified. The results showed that while 88.33% of the farmers were members of a cooperative/union and 57.50% reported timely colostrum administration (within the critical <4 hours), these positive indicators contrasted sharply with low biosecurity and poor practical application. Specifically, calf mortality was high (42.50% of farms reported mortality rates >5%), mainly due to diarrhea and pneumonia, with 65.83% of deaths occurring in the first 30 days. Critical management deficiencies included uncontrolled colostrum feeding (85.00% via suckling, risking failure of passive transfer), severe biosecurity breaches (85.83% of calves housed with adult animals), and delayed introduction of solid feed. In conclusion, the primary challenge in Çorum is not lack of institutional access or basic knowledge, but rather a critical disconnection between theoretical knowledge and practical management implementation. To improve calf survival, management strategies should shift from traditional suckling to controlled colostrum protocols and emphasize the transition from group housing to individual calf hutches to ensure biosecurity.

  General Structure of Cattle Farming Enterprises and Basic Care and Feeding Practices of Breeders: The Example of Çorum City Center

  Bayraktar, Bülent; Tekce, Emre; Aydemir, Seyma; Kotan, Gökşad Cemil; Kebapcı, Eren

  This study examined the general structure of cattle farming operations enterprises in the central district of Çorum city center and the basic care and feeding practices of breeders based on a survey conducted on 130 cattle enterprises between May and June 2023. Cattle enterprises in Çorum city center are generally small to medium-sized; 43.08% of these operations have a capacity of 11-30 animals, while 71.54% are owned by the breeders themselves. Breeders in these operations are predominantly male (82.31%), with the largest age group being between 31 and 40 years old, at 36.15%. Livestock farming is the population source of income for 83.85% of breeders, and their education levels are increasing, with 32.31% of breeders now high school graduates. Breeders combine family knowledge with information from official institutions and organizations as a source of knowledge and experience, and 58.46% rely on experience in their livestock feeding decisions. Animals are generally fed twice a day, with a 90% mix of roughage and concentrate, while automatic waterers (48.46%) are preferred for providing drinking water. However, since 67.69% of concentrate needs are met externally, there is external dependency, and 81.54% of breeders face a pasture shortage. 60.77% of the barns are located adjacent to or below the house, and reinforced concrete (67.69%) is used as the construction material. Regarding cleaning practices, straw (73.85%) is the most preferred bedding material in the barns, general cleaning is done 1-3 times a year, and manure is removed manually and deposited in the open areas (86.15%). 86.15% of breeders are members of breeder associations, and the most frequently received support is pedigree and preliminary pedigree support (89.23%). 68.46% of enterprises maintain an animal registration system. As a result, cattle enterprises in Çorum have a structure that combines traditional methods with modern practices. The breeders' high organizational awareness and propensity for record keeping indicate that the sector has potential for future growth. However, further improvements are needed in areas such as the use of professional nutrition resources and manure management.

  Ultrasonic-Assisted Deep Eutectic Solvent Extraction of Polyphenols From Tea Parts: A Green Assessment

  Gerçek, Yusuf Can; Baştürk, Fatma Nur; Gıdık, Betül; Abca, Tuğba Elbir; Yurtvermez, Bayram; Fuente-Ballesteros, Adrián; Kutlu, Naciye; Ecem Bayram, Nesrin

  Deep eutectic solvents (DESs) have emerged as green alternatives to conventional solvents for extracting bioactive compounds from plants. This study evaluated nine choline chloride–based DESs for recovering antioxidant polyphenols from four parts of the tea plant (Camellia sinensis): seed, bud, leaf, and flower. Total phenolic content, antioxidant activity, and individual polyphenolic profiles were determined, and the greenness of the sample preparation was assessed using AGREEprep. The highest total phenolic content (53.28 mg GAE/g) and antioxidant activity (141.17 mg TE/g) were obtained from leaves using ChCl:formic acid, outperforming ethanol and methanol. Leaves also exhibited the highest total quantified polyphenolic content (up to 95,813 mg/kg DW, corresponding to the sum of the quantified polyphenols), with epicatechin gallate and gallocatechin + epigallocatechin being the major contributors. Flowers and buds showed notable polyphenolic diversity, while seeds contained the lowest levels. Statistical analysis confirmed clear clustering patterns according to plant part and solvent type. AGREEprep evaluation yielded scores up to 0.54, highlighting the environmental benefits of DES-based extraction. We demonstrated that tea leaves were the richest source of bioactive polyphenols, and selected DESs, particularly formic acid–based and ethylene glycol–based, exhibited superior efficiency and sustainability compared to conventional solvents. These findings support the wider adoption of DESs for green, high-yield extraction of pharmacologically important compounds from tea and other medicinal plants.

  Gıdık, Betül; Sağlam, Nilay Özlem

  Tıbbi aromatik bitkiler her geçen gün önemi ve kullanım alanları artan değerli bir bitki grubu halini almaktadır. Özellikle uçucu yağlar yakın zamanlarda sıkça günlük hayatımızda kullanılmaktadır. Lavandin (Lavandula x intermedia Emeric ex Loisel.) çiçek kısımlarında uçucu yağ elde edilen ve parfümeri sanayii başta olmak üzere birçok alanda kullanılan ekonomik değeri olan bir bitkidir. Bu çalışmanın amacı; farklı ekolojik koşullarda yetiştirilen Lavandin bitkisinin antioksidan aktivitesi ve uçucu yağ bileşenlerini belirleyerek ekolojik farklılıkların bu değişkenler üzerindeki etkilerini ortaya koymaktır. Bu amaçla farklı lokasyonlarda yetiştirilen lavandin örneklerinin mikrodalga hidrodistilasyon yöntemi ile elde edilen uçucu yağ oranlarının %0,5-%4,4 değerleri arasında değiştiği görülmüştür. Majör uçucu yağ bileşenlerinin linalool (%13,66-%26,40) ve linalilyl asetat (%10,88-%29,89) olduğu görülmüştür. Lavandin örneklerine ait TP (Toplam fenolik madde) 2,13-4,74 mg GAE/g numune değerleri arasında, TF (Toplam flavonoid madde) 0,43-0,66 mg QE/g numune değerleri arasında, FRAP (Demir (III) indirgeme) 27,62-79,50 µmol Fe2SO4.7H2O/g numune değerleri arasında ve DPPH (radikal temizleme aktivitesi) ise 0,54-1,84 SC50 mg/mL değerleri arasında olduğu belirlenmiştir. Elde edilen sonuçlar, ekolojik koşulların lavandin bitkisi için antioksidan aktivitesi ve uçucu yağ oranında etkili olduğunu ve çalışmada kullanılan bitki materyallerinin parfümeri sanayiinde kullanıma uygun olduğu fikrini desteklemektedir.

  Evaluation of Small Livestock Farms in Çorum Province in terms of Structural Characteristics, Herd Management Practices, Biosecurity and Animal Welfare

  Tekce, Emre; Aydemir, Seyma; Bayraktar, Bulent; Kotan, Gökşad Cemil; Öztürk, Duygu

  This study was conducted to examine the structural characteristics, biosecurity, and animal welfare practices of 120 small ruminant farms in Çorum province. The study included face-to-face surveys, observations, and measurements on farms with at least 50 animals, where a total of 17 different parameters were considered: 7 related to shelters, 7 related to building and equipment conditions, and 3 related to animal health. The majority of participating farm owners were young and middle-aged men who rely on livestock farming as their primary source of income (69%). The sector shows growth potential, demonstrated by the fact that 65% of farmers reported an increase in flock size over the last five years. However, a significant deficiency in modern herd management was identified, as 70% of farms do not use formal record-keeping systems. In terms of biosecurity, although 90.83% of breeders follow a regular vaccination schedule, crucial preventive measures like physical area disinfection and manure removal are performed infrequently, often only once a year. Lack of knowledge about biosecurity and excessive costs were reported as the main obstacles to effective implementation. The welfare assessment, based on the ANI 35L-derived protocol, rated the farms' housing and equipment status as "medium", with critical deficiencies noted in insulation and facilities for heat and cold protection (77.5% lack insulation). However, animal health parameters were generally rated as "moderate", with only skin condition being scored as "good". In conclusion, small ruminant farms in Çorum exhibit growth potential but urgently require improvements in key areas such as record-keeping, biosecurity measures, and modern barn infrastructure to enhance animal welfare and productivity.

  Optimization of Phenolic Compound Extraction from Bee Products via Solvent Systems and PCA Integration

  Birinci, Ceren; Kara, Yakup; Gıdık, Betül; Kolaylı, Sevgi; Can, Zehra

  To achieve a highly selective and sensitive analysis of phenolic compounds in bee products (honey, bee bread, and propolis), a simultaneous quantification of 25 phenolic compounds was performed using high-performance liquid chromatography coupled with a diode array detector. In the study, various solvents were utilized to enhance the phenolic profile of bee products, including pH 2 and 7 ultra-pure water, diethyl ether, and ethyl acetate. These included non-liquid–liquid extraction, pH 2 with 10 mL of pure water and 20 mL of diethyl ether; pH 2 with 10 mL of pure water and 20 mL of ethyl acetate; pH 2 with 10 mL of pure water, 10 mL of diethyl ether, and 10 mL of ethyl acetate; and pH 7 with 10 mL of pure water, 10 mL of diethyl ether, and 10 mL of ethyl acetate. Additionally, the integration of phenolic compounds identified through the enrichment method was pursued using principal component analysis (PCA). The extraction yields and recovery rates of phenolic compounds can be significantly improved by combining and integrating different extraction techniques. Our results demonstrated that using different solvent combinations significantly improved both the yield and diversity of phenolic compounds extracted from the complex matrices of bee products.

  Gıdık, Betül; Can, Zehra; Önemli, Fadul

  Peanut is rich in oil and protein and has a large content of bioactive constituents consisting of tocopherols, phytosterols, and so on. Generally, Virginia, Spanish, Valencia and Runner market types are grown of peanut. In this study, it is aimed to determine the antioxidant activity, total phenolic content and total flavonoid content of peanuts from four different market types, for the first time, and group them with principal component analysis (PCA) and hierarchical cluster analysis (HCA). For PCA, PC1 and PC2 explained 87.655 % of the total variation and, according to the HCA of peanut samples, two main groups were determined. The total phenolic content changed 1.556 to 2.899 mg GAE/g. The lowest value have seen at Spanish merket type to determine the antioxidant activities of peanut samples were maked FRAP and DPPH assay, the lowest FRAP value (8.136 μmol FeSO47H2O/g sample) was seen at Valencia market type, the highest (14.004 μmol FeSO47H2O/g sample) was seen at Virginia market type. It was determined that the total flavonoid, total phenolic content, and antioxidant activities of the Virginia, Valencia, Spanish, and Runner market types included in the study were different from each other, and the Virginia market type showed superior characteristics compared to the others. The results obtained suggest that Virginia market type may be preferred more especially in peanut cultivation for food uses. It is thought that this study can be a source for future studies by eliminating a deficiency in the literature.

  A comparative anatomical study on leaf and scape of Androsace taxa (Primulaceae): contribution to Androsace taxonomy

  Ulcay, Sibel; Sefali, Abdurahman; Yapar, Yakup; Demir, İbrahim; Gıdık, Betül

  In the present study, the leaf and scape anatomical features of ten Androsace taxa distributed in Türkiye were defined to contribute to plant identification. Hand sections from both the scape and leaf examined 43 anatomical characters. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed for the first time for Androsace. The results show that there are differences as well as similarities between Androsace species. It is noteworthy that Androsace artvinensis forms a separate main group with HCA. In addition, the fact that two of the five basic components are represented by a single variable according to the PCA results suggests that the anatomical characters examined are determinative for Androsace taxa.). In PCA, eigenvalues of PC1 (2.435), PC2 (1.749), PC3 (1.369), PC4 (1.223), and PC5 (1.006) were greater than 1.0. Cortex width, aerenchyma, arrangement of vascular bundles, and four-branched non-glandular hairs are among the important anatomical characteristics of the scape. Leaf cross-sectional shape, epidermis dimensions, glandular hair types, presence of five branched non-glandular hairs, stoma sizes, presence of crystals in the mesophyll, and types are among the qualitative and quantitative anatomical characteristics that attract attention in the leaf. This study examined almost all taxa of the genus Androsace distributed in Türkiye. The results will be important in finding new species among the examined taxa and revealing the anatomical features of the taxa for the first time. They will contribute to other studies on the genus.
