The objective of the study was to evaluate the effect of hygiene measures in automatic milking units on the transmission of 3 mastitis pathogens considered to be mainly or partly transmitted from cow to cow during milking events. Two studies were conducted as within-herd experimental trials in 2 Danish commercial dairy herds (A and B) with automatic milking systems. Interventions to enhance hygiene were implemented on the automatic milking units.

- Phenomycin is a small bacterial protein with 89 amino acids that is toxic to mammalian cells and inhibits ribosome function, affecting translation initiation.
- The study reveals that the toxicity of phenomycin is linked to its direct inhibition of protein translation and that effective cellular uptake is hindered by endosomal escape.
- Researchers used high-resolution NMR spectroscopy to analyze phenomycin’s structure and found a specific peptide segment crucial for its toxic effects through comparisons with similar proteins.
Free fatty acid (FFA) concentrations can be elevated in raw milk due to improper handling and management at the dairy farm, and high concentrations of FFA can lead to off flavors in milk. This study aimed to describe how the herd production system, milking system, feeding and technological factors impact on FFA concentrations in bulk tank milk. FFA concentrations in bulk milk samples from 259 organic and 3326 conventional herds were analyzed by FT-IR during one year.

This investigation reveals complex structural rearrangements for this compound as a function of temperature. A room temperature orthorhombic polymorph, α-Sr(BH4)2(NH3BH3)2, with the space group symmetry Pbca, has been determined with a layered structure of alternating ammonia borane and Sr(BH4)2, partially stabilized by dihydrogen bonding.
