Abstract:
... “Pecorino di Farindola” is a traditional ewes’ milk cheese produced in the Abruzzo region (Italy) and ripened for a minimum of 90 days. The main objective of this research was to characterize the microbiological and chemical composition of this cheese, manufactured in ten dairy farms during the winter cheese-making season (December through March). By using classical enumeration system on specific ...

Abstract:
... Fecal pollution enters coastal waters through multiple routes, many of which originate from land-based activities. Runoff from pervious and impervious land surfaces transports pollutants from land to sea and can cause impairment of coastal ocean waters. To understand how land use practices and water characteristics influence concentrations of fecal indicator bacteria (FIB) and pathogens in natural ...

Abstract:
... The effects of hutch coverings utilized during the summer and winter months to moderate extreme temperatures were examined on fecal prevalence of E. coli O157:H7 and Salmonella in newborn dairy calves. In the initial study, the effects of shade using screens in three treatment groups: no shade, partial shade, and full shade were examined. Two additional studies were designed where individual calf ...

Abstract:
... Aims: This study was performed to investigate the microbiological contamination of digestate product (DP) obtained from the anaerobic co‐digestion of bovine manure and agricultural by‐products. Methods and results: Microbiological analyses were performed on bovine manure, fresh DP, liquid and solid fractions and stored liquid fraction of DP. A statistically significant reduction of faecal bacteria ...

Abstract:
... Direct-fed microbials (DFM) have been employed in ruminant production for over 30 yr. Originally, DFM were used primarily in young ruminants to accelerate establishment of the intestinal microflora involved in feed digestion and to promote gut health. Further advancements led to more sophisticated mixtures of DFM that are targeted at improving fiber digestion and preventing ruminal acidosis in mat ...
