    Capripoxviruses were confidently detected in cattle, exhibiting a prevalence of 1.17% (9 out of 770 samples). The PCR products from the infected cattle consistently ranged from 1,000 to 1,500 base pairs, even at very low viral loads. Importantly, no significant differences in infection rates were found between the summer and rainy seasons (P > 0.05), and the prevalence was not associated with specific geographical regions or the timing of blood sample collection (P > 0.05). Notably, infected cattle displayed no clinical signs, such as skin nodules, emphasising that the disease can be present without causing visible harm. These findings strongly reinforce the necessity for stringent disease prevention measures in beef cattle production to effectively mitigate potential losses.

    The crude extract of Amla was found to be effective in treating pre-weaning piglet diarrhea. In this study, the group given a 25% extract concentration showed the most rapid recovery (4.80±0.57 days) and highest body weight gain (3240.00±45.83 g/piglet) over 15 days, outperforming the control group. Additionally, treatment costs were significantly lower in the 25% Amla crude extract group (0.039 USD per piglet) compared to the control group (0.052 USD per piglet). These findings suggested that Amla crude extract could be a cost-efficient alternative for managing pre-weaning piglet diarrhea, especially at a 25% concentration. Moreover, it addressed the issues of treatment expenses and antimicrobial resistance.

    Result elucidated the instances of concurrent infections by crucial pathogens in pigs, which is adversely impacted the herd's health status on a farm located in the Rachaburi province of Thailand. The farm which accommodated a population of 700 sows had found its fattening pig units exhibited unsatisfactory growth performance and an inconsistent size appearance. The serum samples underwent the testing via enzyme linked immunosorbent assay, unveiled a substantial antibody response to the porcine reproductive and respiratory syndrome virus (PRRSV). The finding strongly indicated the prevalence of PRRSV infection within the farm. Furthermore, analysis of lymph node samples confirmed the presence of porcine circovirus type 2 (PCV2) through conventional polymerase chain reaction. The bacterial culture carried out on lung samples which detected an infection caused by Pasteurella multocida. In summary, the investigation is conclusively established the occurrence of a mixed infection involving both viruses and bacteria on this farm, specifically PRRSV, PCV2, and P. multocida. The report is illustrated the possibility of multiple infections by viruses and bacteria, which can potentially undermine the efficacy of vaccinations and cause severe clinical signs on the farm.
