  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.

  Impact of Phytobiotic Supplementation Administered in Drinking Water on Meat Quality in Heat-Stressed Broilers

  Kaya, Hacer; Kamiloğlu, Aybike

  This study evaluated the effects of a phytobiotic additive, hawthorn fruit extract (HFE), administered via drinking water on meat quality of broilers subjected to heat stress (HS). A total of 300 one-day-old broiler chicks were distributed into six experimental groups according to a 2×3 factorial design after a one-week acclimation period, with five replicates of 10 chicks each. Chicks had ad libitum access to feed and water for the duration of the 42-day trial and were exposed to a 24-hour lighting program. HS decreased the b* color value of breast meat while increasing L* and a* values and pH of thigh meat. Cooking loss (CL) of both breast and thigh meat was reduced, whereas water-holding capacity (WHC) remained unaffected. HS did not significantly alter thiobarbituric acid-reactive substances (TBARS), total saturated fatty acids (ΣSFA), or total unsaturated fatty acids (ΣUFA), but decreased monounsaturated fatty acids (ΣMUFA) and increased emulsion stability (ES) and polyunsaturated fatty acids (ΣPUFA). Adding HFE to the drinking water did not influence breast meat pH or color intensity, but WHC improved in breast meat with 0.2 mL/L HFE and in thigh meat at both HFE concentrations. The 0.4 mL/L HFE dose increased ΣSFA and decreased ΣUFA and ΣPUFA levels, while ΣMUFA decreased at both HFE concentrations. Overall, HFE supplementation mitigated several adverse effects of HS, notably enhancing ES and reducing redness of thigh meat. These findings suggest that HFE can be an effective phytobiotic strategy to improve meat quality in broilers under thermal stress conditions.

  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.

  Adverse Effects of Commonly Used Acaricides on the Reproductive Physiology of Drone Honeybees (Apis mellifera L.)

  Erdogan, Yasar

  This study evaluated the adverse effects of three widely used commercial acaricides (amitraz, flumethrin, and formic acid) on the reproductive physiology and quality parameters of drones (Apis mellifera caucasica), commonly used for the control of the destructive pest, Varroa destructor. The experiment was conducted on 20 colonies at the Bayburt University Beekeeping Application and Research Station during the spring-summer of 2025. The acaricides were applied to different experimental groups shortly before the drone cells were capped. Key reproductive quality parameters including body weight, sexual maturity rate, sperm viability, sperm concentration, and semen volume were assessed. The results showed that all three acaricide applications had statistically significant negative effects (p<0.05) on all measured reproductive parameters. Notably, the amitraz and formic acid treatments caused the most significant decreases in sperm viability and sperm concentration. Furthermore, compared to the control group, significant reductions were observed in both sexual maturity rates and drone body weights. The amitraz treatment group, in particular, exhibited the lowest sperm concentration (0.90±0.04×106/μL), a finding that aligns with the most substantial decrease in body weight (52.24 mg lower than the control). These findings clearly demonstrate that the common acaricidal compounds used against Varroa mites pose potential physiological and reproductive risks to drone. This highlights a critical concern for sustainable beekeeping, especially in queen bee rearing programs, and underscores the need for careful consideration of treatment methods and timing.

  The Effect of Pre-Applied Titanium Dioxide Nanoparticles on Germination in Carthamus tinctorius L. Varieties

  Dınler, Burcu Seçkın; Sefaoğlu, Fırat; Gül, Volkan; Çetinkaya, Hatice; Koç, Fatma Nur

  In the present study, to promote sustainable nano-farming, the apparent effects of different concentrations (0, 100, 200, 300, 400, 500 ppm) of titanium dioxide nanoparticle (TiO2NPs) solutions on the germination percentage, index and duration of seeds belonging to Balcı, Dincer, Hasankendi, Koc, Olas, and Zirkon safflower varieties were investigated. Moreover, scanning electron microscopy (SEM) was employed to analyze TiO2NPs in germinated safflower varieties. Germination performance was TiO2NPs concentration and variety depended. It was determined that the seed samples displayed different responses to TiO2NPs concentrations; germination percentages were between 20.0±1.15 and 82.9±0.44%, germination durations were between 2.01±0.021 to 3.82±0.017 days, and germination indices were between 9.97±0.606 and 38.97±0.959. While the highest germination percentage (82.9±0.44%) was obtained from Dincer variety with 100 ppm TiO2NP pre-application, the lowest germination percentage (20.0±1.15% and 20.0±1.92%) was obtained from Balcı and Hasan Kendi varieties with 100 and 300 ppm TiO2NP pre-application. According to this result, although the highest germination percentage based on variety was obtained from the Dincer variety, the Balcı variety with the lowest germination percentage provided the most significant increase in the 200 ppm TiO2NPs application dose compared to the control. According to the germination percentage, it can be said that the most effective TiO2NPs application dose in Safflower varieties is 200 ppm. Further research on nanoparticles is needed to determine both the economical doses of TiO2NP pre-application and its uptake by the plant.

  Determination of Cytotoxic and Apoptotic Properties of Lobaric Acid, a Secondary Metabolite of Lichen and Investigation of Its Theoretical Potential

  Kizil, Hamit Emre; Agar, Guleray; Ekincioğlu, Yavuz

  In this study, we aimed to elucidate some of the mechanisms of cell death induced by lobaric acid in A549 (human lung cancer) cells. For this purpose, the effects of cytotoxic concentrations on p53 and caspase-3 gene expressions were investigated. A549 cells were treated with varying concentrations of lobaric acid (12.5, 25, 50, and 100 µg/ml) for 48 hours and then their viability was evaluated and p53 and caspase-3 mRNA expressions were determined at statistically cytotoxic concentrations of 12.5, 50, and 100 µg/ml. According to beta-actin, it was determined that the increase in lobaric acid concentration revealed an upward trend in p53 and caspase-3 mRNA expressions. Furthermore, quantum chemical parameters such as frontier molecular orbitals, band gap energy and ionization potential, electronic affinity, chemical softness, chemical potential, electrophilicity index and chemical hardness were analyzed. Furthermore, molecular docking was performed to identify the binding sites and the binding behavior of lobaric acid to some target proteins (P53, Caspase-3 and Bcl-2).

  A Study on Occupational Health and Safety in the Agricultural Sector in Türkiye: Analysis of Work Accidents, Occupational Diseases, and Lost Workdays

  Ozdemir, Mustafa

  The agricultural sector holds strategic economic importance due to its roles in food production, employment, and providing raw materials to industry. Türkiye is a significant agricultural country with its biological diversity, favourable climate conditions, and agriculture-based sector. According to the labor force statistics of the Turkish Statistical Institute (TÜİK), as of 2023, approximately 4.7 million people are employed in the agricultural sector in Türkiye, with the majority being seasonal workers. The farm sector includes field farming, livestock, fisheries, and forestry. Occupational Health and Safety (OHS) is vital for the sustainability of the agricultural sector. The Occupational Health and Safety Law No. 6331, which came into force in 2012, has mandated OHS provisions for all enterprises and employees in the agricultural sector. This study examines the statistics on work accidents, occupational diseases, and lost workdays in Türkiye's plant and animal production sector between 2018 and 2022 and evaluates the current state of OHS practices. Based on data from the Social Security Institution (SGK), the analysis reveals that 13,993 work accidents and 96 fatal work accidents occurred in the plant and animal production sector between 2018 and 2022, with the highest frequency of work accidents recorded in 2022. Additionally, 13 cases of occupational diseases were reported during the same period. An examination of temporary incapacity durations shows 133,008 days of incapacity reports, with the highest number occurring in 2021, influenced by the COVID-19 pandemic. The study's findings indicate that OHS practices in the agricultural sector are inadequate and need improvement. In light of these findings, various policy recommendations have been developed, such as the widespread implementation of OHS training, increased health screenings, and stricter OHS inspections.
