RESUMEN
Buffaloes are considered animals of the future with the ability to survive under unfavorable conditions. However, the lack of access to superior germplasm poses a significant challenge to increasing buffalo production. Resveratrol has been shown to improve oocyte quality and developmental competence in various animals during in vitro embryo development. However, limited information is available on the use of resveratrol to improve the in vitro maturation and development competence of Nili Ravi buffalo oocytes. Therefore, the current study aimed to investigate the influence of different concentrations of resveratrol on the maturation, fertilization, and development of buffalo oocytes under in vitro conditions. Oocytes were collected from ovaries and subjected to in vitro maturation (IVM) using varying concentrations of resveratrol (0 µM, 0.5 µM, 1 µM, 1.5 µM, and 2 µM), and the maturation process was assessed using a fluorescent staining technique. Results indicated no significant differences in oocyte maturation, morula rate, and blastocyst rate among the various resveratrol concentrations. However, the cleavage rate notably increased with 1 µM and 1.5 µM concentrations of resveratrol (p < 0.05). In conclusion, the study suggests that adding 1 µM of resveratrol into the maturation media may enhance the cleavage and blastocyst hatching of oocytes of Nili Ravi buffaloes. These findings hold promise for advancing buffalo genetics, reproductive performance, and overall productivity, offering potential benefits to the dairy industry, especially in Asian countries.

Lumpy skin disease (LSD) is a vector-borne viral transboundary disease of cattle caused by the LSD virus (LSDV). Despite investigations on clinical and outbreak features of LSDV, information on disease pathogenesis and alternative changes in blood parameters are scarce. Keeping this in view, the current study was designed to determine haematological, serum biochemical, and oxidative stress parameters in naturally infected cattle with LSDV during the recent surge of outbreaks in Punjab, Pakistan. A total of 35 blood samples was collected from polymerase chain reaction-confirmed LSDV-infected cattle for assessment of all parameters. The haematological examination of blood samples showed a significant reduction (p < 0.05) in different variables of erythrogram and leucogram. On the other hand, differences between levels of various serum biochemical parameters with the significant increase in levels of alkaline phosphatase, serum alanine aminotransferase, aspartate aminotransferase, and blood urea nitrogen were observed in LSDV naturally infected cattle. Moreover, malondialdehyde levels for lipid peroxidation and nitrate concentration were markedly elevated whereas glutathione S-transferase fluorescent and serum superoxide dismutase enzymes showed a decrease in levels. The current study suggests that alternations in haematological and serum biochemical parameters following LSDV infection stimulate oxidative stress and such findings may be useful for early and rapid diagnosis and improvement in the treatment strategy of the disease.
