AbstractHeart rate (HR) and heart rate variability (HRV) were investigated in cows (n=32, age: 3.86 years, milk production: 35±2.5 kg, DIM: 150±15) milked in a parallel milking parlour. Geometric parameters of HRV (SD1 and SD2) were calculated using Poinc... see more

This paper presents the results of a research study which had the objective of investigating the effect of a sprinkler system coupled with forced ventilation on the heat stress of dairy cows bred in a free stall barn without paddock. To this aim, an exper... see more

Contrary to the one-sided straining, after compressive predeformation with subsequent tension the shift of appearing the first stress stall to higher values of strains can be observed. The values of compressive predeformation and the strain of first stres... see more

Eukaryotic DNA replication occurs in the context of chromatin. Recent years have seen major advances in our understanding of histone supply, histone recycling and nascent histone incorporation during replication. Furthermore, much is now known about the r... see more

Communication between the nucleus and mitochondrion could coordinate many cellular processes. While the mechanisms regulating this communication are not completely understood, we hypothesize that cell cycle checkpoint proteins coordinate the cross-talk be... see more

This paper shows the results of a research study aimed at investigating the effects of a sprinkler system coupled with forced ventilation on the heat stress and the behaviour of dairy cows bred in a free stall barn without paddock.To this aim, an experime... see more

Regular physical exercise improves the cardiovascular system function, increases energy metabolism and antioxidant protection, provides greater muscle strength and physical endurance. However, exhaustive physical exercise can cause oxidative stress. Durin... see more
