Effect of experimental Staphylococcus aureus mastitis on compositional quality of goat milk

Effect of experimental Staphylococcus aureus mastitis on compositional quality of goat milk

Infection of 10 dairy goats of mixed breed with Staphylococcus aureus resulted in changes in concentration of certain analytes in milk, which became more pronounced as the infection progressed. Somatic cell counts reached a peak increase of 147% of pre‐infection levels, free fatty acids 49%, sodium...

Description
Summary:Infection of 10 dairy goats of mixed breed with Staphylococcus aureus resulted in changes in concentration of certain analytes in milk, which became more pronounced as the infection progressed. Somatic cell counts reached a peak increase of 147% of pre‐infection levels, free fatty acids 49%, sodium 14%, Chloride 16% and Copper 47%. Decreases in milk concentration included lactose at a maximum 8%, iron at 47%, potassium at 10% and Calcium at 12% of pre‐infection levels. Protein, nitrogen and magnesium levels appeared unaffected by infection. Following curative treatment, changes in the analytes resolved towards normal levels by the fourth week post‐treatment.
