The aim of this study was to investigate the swelling/degradation behaviour of controlled-release system using gelatin, thymol loading capacity, characterisation, morphology and thymol release level in terms of the recommended therapeutic dose for varroosis control. In this context, a series of hydrogels were first produced using glutaraldehyde (GA) crosslinker and swelling tests were performed. Thymol loading was performed on the appropriate hydrogels with swelling values between 269% and 431%. Thymol loading efficiency was determined between 20.07% and 29.80%. The chemical structures of the hydrogels with and without thymol loading were compared by Fourier transform infrared spectrometry (FT-IR) and it was determined that thymol was loaded into the structure. The morphological structures of thymol loaded and unloaded hydrogels were examined by scanning electron microscopy (SEM). It was observed that the non-thymol loaded hydrogel had larger diameter pores than the thymol loaded hydrogel. A model release environment and measurement system were developed to predict the release type, level and duration of the controlled release system in the hive air environment. In this model release environment, release tests were carried out for four weeks using different thymol application systems and the measurements were compared. As a result, it was determined that the controlled thymol release system developed for the control of varroosis infestation exhibited a more stable release compared to existing application systems.

This study was attempted to assess the effects of micellized conjugated linoleic acid (CLA) as a feed additive for suckling calves on their growth performance and blood metabolic, oxidative and immune parameters. Forty-eight Holstein calves were divided among four experimental groups (12 calves/treatment) including: 1) calves with no CLA supplementation (CON), 2) calves supplemented with 1 gr CLA/d as micellized form by dissolving 5 mL/d of a CLA contained emulsion in milk (CLA1), 3) calves supplemented with 2 gr CLA/d as micellized form by dissolving 10 mL/d of a CLA contained emulsion in milk (CLA2) and 4) calves supplemented with 3 gr CLA/d as micellized form by dissolving 15 mL/d of a CLA contained emulsion in milk (CLA3). Calves in the CON group received 10 mL of the emulsion medium with no CLA. Feeding micellized CLA via whole milk resulted in a linear increase in blood concentration of glucose on d 40 (P=0.04), and total protein (P

This study examined the factors influencing pet attachment by investigating attachment dimensions and exploring the relationship between demographic factors and pet attachment. The study utilized the Pet Attachment Questionnaire (PAQ) to assess the level of attachment between pet owners and their animals. A demographic questionnaire was also administered to gather socio-cultural, economic, and health-related data from pet caretakers. A confirmatory factor analysis was applied to confirm the scale factor structure. Hypothesis testing procedures were used to reveal the relationship between the demographic characteristics of the participants and the attachment relationships. The study involved 304 volunteers who visited the animal hospital at Ankara University, Faculty of Veterinary Medicine. The findings revealed significant impacts of various factors on attachment dimensions, including age, household income, participant and household member anxieties and traumas, number of pets owned, pet health, and previous pet ownership. These results contributed to our understanding of the complex dynamics that shape the attachment between humans and animals. Further research is needed to delve into the underlying mechanisms and potential interactions among these factors, advancing our knowledge of human-pet attachment.
