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.

İncele - MakaleAçık Erişim2026General 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.

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.

The study aims to investigate the relationship between relative telomere lengths and various physiological parameters in cattle infected with bovine leukosis virus, as well as to identify the risk factors associated with cow-level bovine leukosis virus infection in dairy cattle in Türkiye. Three variables—age, parity, and body condition score—were used for risk assessment. Antibodies specific to bovine leukosis virus were detected using an enzyme-linked immunosorbent assay, and relative telomere lengths were measured by polymerase chain reaction. The highest seropositivity rate (39.13%) was observed in cattle with a body condition score of 3–3.5 and aged between 2–8 years. relative telomere length was found to be positively correlated with seropositivity, advanced age, and parity, while a negative correlation was observed between seropositivity and body condition score. Relative telomere lengths in bovine leukosis virus-infected cattle were significantly shorter (P < 0.05) than those in non-infected cattle. Among body condition score groups, the shortest relative telomere lengths were found in bovine leukosis virus-infected cattle with body condition score ≤ 2.5 and in non-infected cattle with body condition score 3–3.5. Regarding age groups, the shortest relative telomere lengths were observed in bovine leukosis virus-infected cattle older than 8 years (P < 0.05), as well as in non-infected cattle of the same age group (P < 0.05). In conclusion, relative telomere lengths in bovine leukosis virus-infected cattle were found to be significantly shorter than in non-infected cattle (P < 0.05). The shortest relative telomere lengths were recorded in both bovine leukosis virus-infected and non-infected cattle over 8 years of age (P < 0.05). Finally, the association between bovine leukosis virus infection and relative telomere lengths, along with other factors such as age, parity, and body condition score, is considered potentially useful for disease control and prevention programs.

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.

AtıfOpenAlex1TR Dizin1İncele - MakaleAçık Erişim2021Osmotic Dehydration Applications in Meat
Kantar, Naciye Kutlu; Kamiloğlu, Aybike; Elbir, Tugba
Osmotic dehydration is a non-thermal, partial drying process applied for the removal of water in food products, as well as for the absorption of various solutes (salt, sugar, etc.). In the osmotic dehydration process, the food material is immersed in a high concentration solution to obtain a final product with lower water activity. However, since the final products with very low water activity cannot be obtained with osmotic dehydration, this method is applied as a pretreatment. The water loss in the product takes place in a shorter time with the osmotic dehydration process applied before drying. The most effective factors on osmotic dehydration are the type of osmotic agent, concentration, process temperature, process time and sample/solution ratio. The low process temperature in osmotic dehydration prevents the loss of color and aroma in food products and contributes the functional, nutritional and sensory properties of products. In addition, the fact that it is a very economical process and does not pose any negative effects in terms of human health makes the method advantageous. In this review, when the osmotic dehydration process is used as a pretreatment in meat processing, the effects on the quality characteristics of the product were mentioned. It has been determined that osmotic dehydration used in various meats (chicken, pork, beef, lamb, ostrich meat and a wide variety of seafood) improves many quality parameters such as color and sensory properties and shelf life of the products. Dried meat with better texture were obtained with the use of specific osmotic agents. It is also recommended to use osmotic dehydration in combination with some applications such as ultrasound or high pressure for effective drying of meat. It was determined that osmotic dehydration process used before convective drying significantly reduced the drying time of meat.

In this study, the quality of produced products have a great importance. For this purpose, raw milk samples is obtained from Atatürk University Dairy Plant for every four seasons separately (summer, autumn, winter, spring) to protect human health and produce quality products. Physical and chemical properties (dry matter, fat, ash, protein, specific gravity, acidity and pH) of raw milk samples and microbiological (somatic cell count, total aerobic mesophilic bacteria (TAMB), mould, yeast, coliform bacteria and Staphylococcus aureus (S. aureus)) properties were investigated. Dry matter, ash (P<0.05) and fat (P<0.01) values of raw milk samples were affected significantly by dairy farm, meanwhile protein, specific gravity, pH and acidity values were not affected (P>0.05). Seasons had a significant effect on dry matter, protein, fat (P<0.05), ash and pH (P<0.01) values of raw milk samples. But, seasons did not have a significant effect on only specific gravity and acidity values (P>0.05). TAMB, yeast, mould counts indicated significantly changes based on dairy farms and seasons. On the other hand, coliform bacteria was not affected (P>0.05) by dairy farms and seasons. S. aureus counts were affected statistically by only seasons (P<0.01).

Ecem Bayram, Nesrin
The aim of this study was to assess the quality of five propolis samples obtained from Turkey (TP), China (CP), Brazil (BP1, BP2), and Ethiopia (EP). The phenolic compounds of the propolis were identified and quantified using the liquid chromatography-tandem mass spectrometry technique (LC-MS/MS). In addition, quality parameters such as total flavonoid content, total phenolic content, free-radical scavenging activity and element contents were investigated. As a result of LC-MS/MS analysis, the extracts were sorted as TP> BP1> BP2> CP> EP in terms of the total concentration of individual phenolic compounds. Chlorogenic acid was determined as the dominant compound in BP1 and EP, p-coumaric acid as the dominant compound in the BP2 and trans-ferulic acid as the dominant compound in the samples from CP and TP. The concentration of DPPH was higher in TP whereas the ABTS concentration was almost similar to other propolis extracts. The contents of potassium (K), calcium (Ca), iron (Fe), magnesium (Mg) and sodium (Na) in the propolis samples were in the range of 2416.75-14416.02 mg/kg, 8.52-613.25 mg/kg, 102.66-1425.82 mg/kg, 523.84-7336.74 mg/kg and 57.65-191.15 mg/kg, respectively. Consequently, it is again supported that chemical characteristics and activity of propolis varies according to its geographical origin with this study.
