Milk is a complex fluid required for development, nutrition and immunological protection to the newborn offspring. Interestingly, latest finding proved the presence of novel stem cell population in human milk with multilineage differentiation potential. Given that little is known about cellular milk content in other mammalian species such as bovine, the purpose of our study was to isolate and characterize a potential stem cell-like population in bovine milk.

- Iodine deficiency is still a major health issue in various countries, prompting a study on the impact of the marine alga Ascophyllum nodosum as an iodine supplement in cow diets.
- The inclusion of A. nodosum in cow diets significantly increased the iodine levels in milk while reducing free amino acids without affecting free fatty acids.
- Additionally, the study found notable changes in the milk’s microbiological quality, enhancing beneficial bacteria and improving overall milk hygiene and processing.
The aim of the study was to investigate the possibility to differentiate the 4 most important species in Italian dairy industry (cow, buffalo, sheep, and goat), applying a bottom-up proteomic approach to assess the milk species involved in cheese production. Selective peptides were detected in milk to use as markers in cheese products. Trypsin-digested milk samples of cow, sheep, goat, and buffalo, analyzed by HPLC-tandem mass spectrometry provided species-specific peptides, some of them recognized by Mascot software (Matrix Science Ltd.
