Öğe Türü: Öğe , Determination of fattening performance, some slaughter and carcass traits of blonde d’Aquitaine, charolais, limousin and simmental cattle(Afyon Kocatepe Üniversitesi, 03.10.2025) Koçak, Serdar; Demirtaş, Mustafa; Çinkaya, Samet; Yıldırım, KemalThis study aims to evaluate the fattening performance and some slaughter and carcass characteristics of four different cattle breeds (Blonde d’Aquitaine, Charolais, Limousin, and Simmental) fattened in a private enterprise in Türkiye. Data from a total of 120 imported male cattle were used in the research. These animals were placed on a fattening with an average initial live weight of 294.10 kg. In this study, parameters such as average daily live weight gain, slaughter weight, carcass weight, and dressing percentage were examined. Statistical analyses were performed using analysis of variance (ANOVA) and multiple comparison tests. The average daily live weight gains for Blonde d’Aquitaine, Charolais, Limousin, and Simmental bulls were found to be 1.416±0.035, 1.641±0.060, 1.457±0.024, and 1.538±0.082 kg, respectively, with a significant difference among breeds (p<0.05). The dressing percentages for these breeds were determined as 58.90±0.41%, 58.20±0.80%, 59.10±0.30%, and 56.50±1.00%, respectively. The results revealed statistically significant differences among breeds in terms of initial live weight, daily live weight gain, and slaughter weight (p<0.05). In particular, the Charolais breed stood out for its higher average daily live weight gain. It was also concluded that the Simmental breed shows similarities to specialized beef breeds in certain traits and has potential as an alternative. The findings obtained from this study can provide valuable insights to producers regarding productivity and performance when selecting cattle breeds for fattening.Öğe Türü: Öğe , Determination of risk factors in beekeeping enterprises in Burdur province(Afyon Kocatepe Üniversitesi, 03.10.2025) Akın, Ahmet CumhurTürkiye holds a significant place in global honey production rankings; however, its yield per hive remains below the world average. According to 2022 data, there is a 3.78-fold difference in hive yield between Türkiye, which ranks third globally in the number of hives, and China, which holds the second position. This situation highlights the need to improve hive productivity to ensure the sustainability of the Turkish beekeeping sector. Numerous direct and indirect risk factors contribute to the sector’s inability to achieve adequate productivity. Türkiye’s diverse and varied geographical structures result in these risk factors varying from region to region. In this context, the study aims to identify the risk factors encountered by beekeeping enterprises in Burdur province, located in the Western Mediterranean Region, throughout the production to marketing process. As part of the research, beekeeping enterprises included in the 2025 sample were visited, and the “Beekeeping Risk Factor Scale” was administered. As a result of the exploratory factor analysis conducted on the applied scale, a four-factor structure was identified, explaining a total variance of 71.413%. This structure comprises 25 items. The variance explained by each factor is as follows: 21.826% by socioeconomic factors, 19.394% by technical factors, 12.767% by factors related to itinerant beekeeping, and 10.769% by factors related to marketing. As a result, it is crucial for the sustainability of the sector that both beekeeping enterprises and policymakers acknowledge the risk factors identified in Burdur province. Developing solution-oriented policies and implementing measures to mitigate these risks are of great importance.Öğe Türü: Öğe , Manda yıldızı ve çolpan yazılımları ile hayvan ıslahı amaçlı veri yönetimi(Afyon Kocatepe Üniversitesi, 03.10.2025) Tekerli, Mustafa; Eser, Orhan; Demirtaş, Mustafa; Çinkaya, Samet; Çelikeloğlu, Koray; Kaplan, Yusuf; Alkoyak, KürşatHayvancılıkta verimliliğin ve sürdürülebilirliğin temeli, doğru ve sistematik veri kaydına dayanmaktadır. Geleneksel kayıt tutma yöntemleri; veri kaybı, tutarsızlık ve analiz zorlukları gibi ciddi kısıtlamalar getirmekte, bu durum ulusal ıslah programlarının etkinliğini düşürmektedir. Bu çalışma, Tarım ve Orman Bakanlığı tarafından yürütülen Halk Elinde Hayvan Islahı Ülkesel Projeleri’nin ihtiyaçlarına yönelik geliştirilen ve dijital dönüşümü destekleyen iki bilgisayar yazılımının katkılarını ortaya koymayı amaçlamaktadır. Bu kapsamda, küçükbaş hayvan yetiştiriciliği için web tabanlı yazılım Çolpan, manda ve yerli sığır yetiştiriciliği için ise Windows tabanlı yazılım Manda Yıldızı geliştirilmiştir. Çolpan, Delphi ve IntraWeb framework'ü kullanılarak web mimarisi ile tasarlanmış, Manda Yıldızı ise Delphi VCL ile yerel masaüstü uygulaması olarak kodlanmıştır. Her iki sistemin veri yönetimi, veri tabanı ile entegre edilmiştir. Yazılımlar; soy kütüğü ve fenotipik ölçüm verilerinin merkezi ve güvenli bir yapıda toplanmasını, işlenmesini ve analiz edilmesini sağlamaktadır. Rol tabanlı erişim kontrolü sayesinde veri güvenliği ve yetkilendirme temin edilmekte, proje paydaşlarının sahadaki verileri anlık olarak izlemesine ve raporlamasına olanak tanınmaktadır. Sonuç olarak, bu programlar ıslah projelerinde veriye dayalı karar alma süreçlerini güçlendirerek ilerlemeyi hızlandırmakta ve sürdürülebilirliğe önemli katkılar sunmaktadır.Öğe Türü: Öğe , Investigation of the effects of polydatin on gentamicin-induced renal toxicity in rats(Afyon Kocatepe Üniversitesi, 03.10.2025) Kandemir, Özge; Şimşek, Hasan; Akaras, Nurhan; Kandemir, Fatih MehmetGentamicin (GNT), an aminoglycoside antibiotic, induces nephrotoxicity through mechanisms like tubular apoptosis and inflammation. Polydatin (Poly), a natural polyphenolic compound with antioxidant and anti-inflammatory properties, has shown potential in alleviating renal damage. This study aimed to investigate the protective effects of Poly in rats with GNTinduced kidney injury using biochemical, molecular, and histopathological methods. 35 Wistar albino rats were divided into 5 groups (7 rats/group), including control, Poly (100 mg/kg), GNT (100 mg/kg), and two combined treatment groups (GNT+Poly at 50 mg/kg and 100 mg/kg). After 7 days of treatment, kidney tissues and blood were collected for analysis of renal function markers, oxidant-antioxidant parameters, gene expression (NF-κB, TNF-α, Caspase-3, Bax, Bcl-2, KIM1, AQP2), and histopathological evaluation. GNT increased serum urea and creatinine levels (p<0.001), increased MDA levels (p<0.001) and decreased antioxidants (p<0.001); also increased the expression of NF-κB and TNF-α (p<0.001), increased Caspase-3 and Bax (p<0.001) and decreased Bcl-2 levels (p<0.001). When administered together with GNT, Poly decreased MDA levels (p<0.001) and increased GSH levels (p<0.001), decreased inflammation markers (NF-κB and TNF-α) (p<0.01), decreased Caspase-3 and Bax (p<0.01) and increased Bcl-2 levels (p<0.01), and also improved histological damage and decreased histological score (p<0.05). In GNT-induced renal toxicity, Poly 100 treatment provided renal protection by reversing oxidative stress, inflammation, and apoptosis.Öğe Türü: Öğe , Determination of systemic inflammation and diagnostic markers using iron parameters in foals infected with rhodococcus equi(Afyon Kocatepe Üniversitesi, 03.10.2025) Deniz, Ömer; Atak, BedihaRhodococcus equi is a significant respiratory pathogen in foals, particularly those under six months of age. This study aimed to evaluate the effects of R. equi infection on serum iron (Fe), unsaturated iron-binding capacity (UIBC), and fibrinogen (Fbg) concentrations. Fifteen foals with confirmed R. equi pneumonia and ten healthy control foals were included. Infected foals were treated with oral azithromycin and rifampicin for 15 days. Samples were collected on days 0, 7, and 14, and Fe, UIBC, and Fbg levels were analyzed. Statistical analysis showed significantly higher UIBC and Fbg levels in the infected group at the start of treatment compared to controls (p=0.004 and p<0.001, respectively). Serum Fe levels did not differ significantly between groups (p=0.138), though a trend toward lower levels in infected foals was noted, reflecting the inflammatory response. Changes in UIBC and Fbg levels reflect the progression of infection and response to treatment. Among the parameters evaluated, fibrinogen appears to be the most reliable biomarker for monitoring systemic inflammation during R. equi pneumonia in foals. However, the diagnostic value of iron parameters warrants further investigation with larger sample sizes and time-point-specific analyses.
