Title: Influence of Addition of Newly Drawn Milk and Fluctuating Temperatures of Farm Bulk Tanks on Growth of Mastitis-Causing Bacteria
Abstract: Effect of addition of newly drawn fresh milk of consecutive milkings on growth of Staphylococcus aureus , Staphylococcus epidermidis , Streptococcus agalactiae , Streptococcus dysgalactiae , and Streptococcus uberis in milk held at fluctuating temperatures of a farm bulk tank for 48 h was studied. There was a statistically insignificant effect of the addition of newly drawn fresh milk of consecutive milkings on the growth rate of S. aureus , S. epidermidis , S. agalactiae and S. uberis but there was a significant (p<0.001) growth enhancing effect on S. dysgalactiae . However, all the bacteria grew significantly (p< 0.001) in milk held at fluctuating temperatures of farm bulk tank for 48 h.
