Effect of dietary zinc supplementation of Friesian cows on chem.-nutritional and aromatic properties of Caciocavallo cheese after 7 days (C7) and 120 days (C120) of ripening. The control group (CG) was fed with a conventional complete diet, while the exptl. group (zinc group, ZG) received a daily zinc supplementation of 60 mg for kg of dry complete feed. During the exptl. period, the milk yield was monitored and samples of milk and caciocavallo cheese were collected and analyzed for chem.-nutritional composition and aromatic profile. The enrichment of dairy cows diet with zinc, did not influence milk yield and composition, however a marked reduction of somatic cell count was evidenced. Both in milk and cheese the ZG samples were characterized by a lower concentration of satured fatty acids and an increase in oleic, vaccenic and rumenic acids. The aromatic profile of dairy products was also pos. affected by dietary zinc intake, with an increase in concentration of carboxylic acids, esters and lactones. The present results suggest a pos. role of dietary zinc intake in improving the quality of bovine milk and related cheese, in particular for the increase in concentration of bioactive fatty acids such as rumenic acid. The changes evidenced in cheese through the anal. of the volatile profile, would be consistent with the development of interesting organoleptic properties, although further evaluations should be performed to confirm the consumer acceptability of these changes.
