Abstract: CAGA, JANINA KAY R., Detection of Subclinical Mastitis in Dairy Goats (Capra hircus) in Selected Farms from Cavite and Batangas. Undergraduate Thesis. Doctor of Veterinary Medicine. Cavite State University, Indang, Cavite, 2017. Adviser: Chester Joshua V. Saldafia, DVM, MSc. A study was conducted to detect the presence of subclinical mastitis in raw milk of dairy goats in Cavite and Batangas. A total of 58 milk samples from dairy goat farms in Trece Martires City, Cavite and Nasugbu, Batangas were enrolled in the study. Milk samples were collected and processed immediately for California Mastitis Test (CMT). Further test were conducted in the laboratory to determine the Somatic Cell Count (SCC) using Fossomatic™ FC and the Total Viable Count (TVC) of milk samples by serially diluting the milk up to 10’ using normal saline solution as diluent, plated onto Nutrient Agar plates and incubated at various temperatures. The study revealed that 51.72% (30/58) of the total dairy goats are positive for subclinical mastitis. Twenty three 23 (60.53%) out of 38 goats from Nasugbu, Batangas and 7 (35%) out of 20 samples from Trece Martires City, Cavite were positive for subclinical mastitis. The Total Viable Count (TVC) of fresh goat milks ranged from 9 x10° to 1.5 x 10%. The mean viable count at 37°C incubation is 6.67 x 10° cfu/mL. This is higher compared with the viable counts with mean of 6.62 x 10° cfu/mL at 25 °C. However, no growth was observed at 5 “C and 59 °C. Furthermore, the presence of subclinical mastitis was statistically associated with the total viable count. The somatic cell count (SCC) of fresh goat milks from Trece Martires City, Cavite ranges from 2.8 x 10* to 1.62 x 10’ with mean of 1.94 x 10° cfu/ml while the SCC of fresh goat milks from Nasugbu, Batangas ranges from 2.4 x 10* to 1.89 x 10’ with mean of 2.05 x 10° cfu/ml. Moreover, the Total Viable Count (TVC) and Somatic Cell Count (SCC) both have a sensitivity of 100% and a specificity of 67% and 100% respectively. This means that if mastitis is present, there is a 100% chance that TVC and SCC will detect it. The Somatic Cell Count (SCC) is a dependable test to diagnose subclinical mastitis in buffaloes like the California Mastitis Test (CMT) that are commonly used in dairy farms. This study revealed that the subclinical mastitis is prevalent in milking goats in Cavite and Batangas.
