Article Synopsis
- Bovine respiratory disease (BRD) significantly affects mortality, animal welfare, and production efficiency on farms, and this study focuses on optimizing the use of pulmonary ultrasonography for diagnosis in calves.
- The research involved evaluating the diagnostic effectiveness of targeted lung ultrasonography on specific lung lobes compared to comprehensive scanning, using data from 193 Holstein and 112 Angus calves.
- Findings suggested that the right cranial lobe, especially in combination with either the left cranial lobe or middle lobe, provided the best sensitivity (over 94%) for diagnosing lung consolidation in various prevalence scenarios.
Article Synopsis
- - The study focuses on a significant pathogen affecting nursing calves globally, analyzing the gut microbiota of dairy calves within their first month of life on a Brazilian farm.
- - Researchers collected fecal samples from 30 calves and tracked their fecal scores, discovering that all calves experienced diarrhea starting on day 5, with all testing positive for the pathogen at some point.
- - The findings indicate that while microbiota richness typically increases as calves age, this growth is hindered by diarrhea, which also alters the composition of the gut microbiota.

Bovine anaplasmosis is endemic and is of fundamental importance worldwide. Therefore, measures for controlling and preventing clinical diseases are warranted to ensure the reduction of associated economic losses. The objective of the present study was to assess the post-inoculation effects and protection conferred by three different protocols of inoculation of low-virulence live strains of Anaplasma marginale (UFMG1 and UFMG3) in field-challenged cattle.

This study aimed to assess the prevalence of hemopathogens in bovine fetuses at various gestational periods. Samples were obtained from a slaughterhouse in the state of Minas Gerais, Brazil, and a total of 236 fetuses were collected.
