Abstract
Somatic cell counts enhancement which is accompainied bacteria pathogen is an indication subclinical mastitis (SCM) in Ettawa crosbred goat (PE). The objective of this study was to type of bacterial, somatic cell counts (SCC), and its impact on milk yield (MY) in PE goat SCM in Sleman, Yogyakarta. This study was conducted in Sleman PE goat farm with PE goat SCM (n=10) and no SCM (n=10). Determination of PE goat SCM based on California Mastitis Test (CMT) and followed with calculation SCC by the Breed method. Isolation and identification bacteria in PE goat SCM and no SCM based on bacteriological analytical manual (BAM). The PE goats milk production was monitor everday during one week. The average of SCC in PE goat SCM is 3.72 x 106cells/ml, while no SCM is 1.75 x 105 cells/ml. Bacterials from PE goat SCM is Staphylococcus aureus sp (50%), Pseudomonas sp (40%), Streptococcus sp (30%), Staphylococcus epidermidis (20%), Staphylococcus intermedius (20%), Corynebacterium sp (20%), Coliform sp (10%), and Bacillus sp (10%), while bacteria in PE goat no SCM is Coliform sp (40%), Staphylococcus epidermidis (20%), Staphylococcus intermedius (10%), Streptococcus sp (10%), and Bacillus sp (10%). The average of milk production in PE goat no SCM is 1.38 liter/day, while in PE goat SCM is 0.35 liter/day. Staphylococcus aureus is responsible bacteria in PE goat SCM which causes decrease the milk production than others bacteria.
