The present study aims to explore the potential biomarker application of salivary heat shock 70 kDa protein in detecting thermal stress in dairy animals noninvasively. The study spans for 45 days during the mid-summer season (April-May), involving twelve multiparous non-pregnant adult Jersey crossbred cows by randomly allocating them into groups (six animals in each group). The control animals were maintained in the shed, whereas the thermal stress group animals were exposed to environment heat between 10:00 h to 16.

- Macrophages play a crucial role in the immune response, but cattle are vulnerable to heat stress which affects their immune cells.
- This study investigates how high temperatures and lipopolysaccharide (a component of bacterial cell walls) impact the function and molecular response of bovine macrophages in a lab setting.
- Findings indicate that heat and lipopolysaccharide exposure leads to increased cell death, reduced immune function, and altered gene expression, contributing to a higher risk of disease in cattle experiencing heat stress.
Rhipicephalus sanguineus sensu lato (s.l.), the brown dog tick, transmits several important haemo-protozoan and rickettsial pathogens to dogs.

- Despite adequate iron levels in pregnant sows, piglet iron reserves are low, suggesting issues with how iron is transferred through the placenta.* -
- The study found that the expression of iron regulatory proteins hepcidin and ferroportin in the placenta was linked to non-heme iron levels, inflammation, and oxidative stress.* -
- Hepcidin showed a positive association with inflammatory markers, while ferroportin had a negative association, indicating they might regulate iron movement and inflammation at the placental level.*
Vapour patches dispensing pheromones were evaluated as lures to increase the attractiveness of sticky tick traps for Rhipicephalus sanguineus sensu lato (s.l.).
