This study examines how thermal conditions influence mineral metabolism in rabbits. The objective of the research is to assess the effects of low temperatures on the levels of calcium, phosphorus, potassium, magnesium, and iron in rabbit blood serum. Spectrophotometric chemical analyses were performed on blood samples collected from rabbits exposed to cold. Results show that low temperatures induce alterations in the concentrations of key macroand microelements (Ca, P, K, Mg, Fe) that are essential for multiple physiological functions. These changes indicate a direct impact of cold on mineral metabolism and suggest the need to adjust rearing conditions in order to maintain mineral balance and ensure animal health.

The study of the innervation of the coxofemoral joint in dogs is becoming increasingly topical in the treatment of hip dysplasia and other conditions that evolve in parallel. The knowledge of the topography and distribution of the nerve supply, the morphologic and structural interpretation of the sources of innervation is of essential anatomic-clinical and therapeutic interest in dogs with hip dysplasia and arthrosis, especially senile dogs with joint dysfunction accompanied by pain and functional disorders. The research was carried out in the Veterinary Medical Center of the Technical University of Moldova, using fine anatomical dissection according to Vorobiov, V.P. (1958) and the Erlich-Dogel staining method, on 26 coxo-femoral joints from 13 canine cadavers of different breeds, ages and sex. The methodology included macroscopic and microscopic techniques to reveal nerve tracts. The results show that the innervation of the coxo-femoral joint derives from the Plexus lumbalis caudalis (L3-L6) and the Plexus sacralis cranialis (S1-S2), forming a complex lumbosacral plexus. The main nerves involved are: N. femoralis (L4-L5), cranioventrally innervating the joint capsule; N. obturatorius (L4-L6), with caudoventral fibers; N. gluteus cranialis (L6-S1), distributing craniolateral branches and N. ischiadicus (L6-S2), contributing dorsocaudally. These somatic fibers also have a vasomotor role, being satellites of blood vessels. Contrary to other studies, the N. gluteus caudalis has not been identified as a source of innervation of the coxo-femoral joint capsule in the dog. The data obtained provide a detailed topography of the nerve tracts, essential for surgical interventions and nerve blocks. This information has major clinical implications, facilitating the management of hip dysplasia and arthrosis in dogs through precise treatments based on a thorough understanding of joint innervation.

Heat stress is a major challenge and is one of the main environmental stressors with substantial economic losses in the rabbit industry. Rabbits are more sensitive to heat stress, compared to other agricultural animals, because they have few sweat glands, and their body is covered with thick fur. Heat stress negatively influences the health of rabbits, their reproductive properties, growth and productivity, characteristics of rabbit products, antioxidant properties, immune response, histomorphology and intestinal microbiota. Currently, one of the real strategies for mitigating the unfavorable influences of heat stress can be the use of nutraceuticals with targeted properties in improving the development of the intestinal microbiota, enhancing antioxidant properties, stimulating the immune system, increasing the productivity and resistance of the rabbit's body to diseases, in the physiological maintenance of the chemical composition and biophysical characteristics of rabbit products. This article summarizes the recent information on the negative impact of increased temperatures on rabbits and the advantages of heat stress mitigation strategies.

Helminth infestations represent a major challenge for the health and productivity of cattle, causing significant economic losses and affecting the sustainability of farms. The control of these parasites with anthelmintics is essential, but emerging resistance to treatments requires periodic evaluation of the efficacy of the preparations used. The present study aimed to test the efficacy of the veterinary drug Albendazole 10%, oral solution, produced by SRL "Medicamentum", on helminthiasis in cattle. The research was carried out on a herd of 40 cattle, divided into two batches, within the professional farm "Confort", Petrești, Ungheni district, during the period March-June. Helminthiasis diagnosis included epizootological examination, clinical evaluation and coprological tests by standardized methods (Fulliborn, Willis, Darling and Baerman). The indices of extensive invasion (E.I.) and intensive invasion (I.I.) were calculated before and after deworming, and the efficacy was assessed by intensive efficacy (I.E.) and extensive efficacy (E.E.). The results revealed a significant reduction in the parasitic load in the treated group, with I.E. values over 98% and average E.E. of approximately 89%. The study demonstrates the high efficiency of the veterinary drug Albendazole 10% in the control of gastric and respiratory helminthiasis in cattle, contributing to the consolidation of deworming strategies and the prevention of the spread of anthelmintic resistance.

Primary hypoadrenocorticism (Addison’s disease) is an uncommon but potentially life-threatening endocrine disorder in dogs. Affected animals may present with clinicopathological features mimicking acute kidney injury (AKI). The challenge in diagnosing hypoadrenocorticism arises from its highly heterogeneous and non-specific clinical presentation, including acute kidney injury (AKI). This retrospective observational study aimed to evaluate dogs presenting with AKI and to identify cases in which primary hypoadrenocorticism was the underlying etiology. Thirty-four dogs diagnosed with acute kidney injury were evaluated at the Clinical Hospital for Companion Animals of the “Ion Ionescu de la Brad” University of Life Sciences, Iași, Romania, among which three (8.8%) were endocrinologically confirmed to have primary hypoadrenocorticism. The evaluation protocol included a complete clinical examination, hematological, biochemical, and hormonal investigations, urinalysis, abdominal ultrasonography, and an ACTH stimulation test. These dogs exhibited hyponatremia, hyperkalemia, a reduced sodium-to-potassium ratio, and azotemia at admission, closely resembling intrinsic AKI. Following fluid therapy and hormone replacement, rapid normalization of electrolyte and renal parameters was observed. These findings support hypovolemia and electrolyte imbalance as the primary mechanisms underlying reversible prerenal azotemia in these cases. If not diagnosed early, this condition has a significant risk of progressing to acute tubular necrosis. The findings highlight the need for careful differentiation between primary AKI and renal dysfunction secondary to Addison’s disease, as well as the importance of promptly initiating hormone replacement therapy. In conclusion, hypoadrenocorticism should be considered in dogs presenting with AKI and electrolyte imbalance. Early endocrine evaluation and prompt initiation of targeted therapy are essential to avoiding misdiagnosis and optimizing clinical outcomes.
