The study aimed to evaluate the changes in milk from goats with mastitis by using the strip cup test, California Mastitis Test (CMT), somatic cell count (SCC) and microbiological profile as well as to determine the biochemical profile, especially acute phase proteins, in blood serum and whey from goats with naturally occurring clinical or subclinical mastitis. Three experimental groups were formed by 30 mammary glands from healthy goats with milk samples negative to strip cup test, CMT and microbiological examination (control group - G1); 30 mammary glands with milk samples negative to strip cup test but with moderate (2+) or intense (3+) reaction in CMT and microbiological examination (group with subclinical mastitis - G2), and 12 mammary glands with positive results to strip cup test and microbiological examination (group with clinical mastitis - G3). After asepsis of the teats milk samples were collected for SCC, microbiological culture, and to determine the biochemical profile in whey, including proteinogram by fractionation in poliacrylamide gel electrophoresis (SDS-PAGE). At the same time, blood samples were obtained to determine the serum biochemical profile. Automatic and microscopic methods were higher in milk samples from goats with subclinical mastits (G2: 4,500.000 cells/mL e 20,830,000 cells/mL, respectively) e with clinical mastitis (G3: 7,500,000 células/mL e 39,100,000 cells/mL, respectively). Staphylococcus aureus, Coagulase-negative Staphylococcus (CNS), Coagulase-positive Staphylococcus (CPS), Corynebaterium spp. and Streptococcus spp. were the microorganisms isolated in milk samples from goats of G2 and G3. Whey samples from goats of G2 and G3 showed higher activity of alkaline phosphatase (G2: 122 U/L and G3: 207 U/L) and gamma-glutamyltransferase (G2: 483 U/L and G3: 571 U / L), and higher concentrations of albumin (G2: 0.18 g/dL and G3: 0.29 g/dL), total protein (G2: 1.50 g/dL and G3: 1.67 g/dL), chlorides ...
