Mastitis is one of the most common diseases in dairy cattle. It significantly reduces milk quality and yield, thus incurring economic losses for farmers. This study investigates the impact of various bacterial pathogens on the somatic cell count, milk composition, and technological properties of milk samples from 302 clinically healthy Polish Holstein-Friesian cows kept under intensive rearing conditions.

Herd-I, consisting of Polish White (PWI) and Fawn Improved (PFI) goats, received supplementation with organic or inorganic selenium (controls). All goats were free from parasites, mastitis, and small ruminant lentivirus infection.

This can cause increased levels of stress, which many studies have shown is a factor resulting in reduced self-esteem, which affects not only the well-being of nurses but also the quality of care provided.
Aims: To investigate the relationship between the self-assessment of nursing competencies and self-esteem among novice nurses and the moderation role of the sociodemographic variables and intention to leave the nursing profession on this relationship.
Polymorphisms of milk protein genes have been proposed as candidate markers for dairy production traits in cattle. In the present study, a polymorphism was detected in the 5'-flanking (promoter) region of the bovine alpha-lactalbumin (LALBA) gene, a T/C transition located at nucleotide -1,001 relative to the transcription start site g.-1001T > C (NC_037332.

In aqueous solution, both chlorido complexes aquate fully to the corresponding aqua complexes, viz. [Ru(terpy)(bipy)(HO)] and [Ru(terpy)(en)(HO)], within ca.
