EFFECTS OF MILKING PRACTICES ON BACTERIOLOGICAL QUALITY OF RAW MILK FROM SELECTED DAIRY FARMS WITHIN SOKOTO METROPOLIS

Abstract

ABSTRACT This study was design to determine the effects of milking practices on the bacteriological quality of raw milk from selected dairy farms within Sokoto metropolis. Five (5) dairy farms were selected, 100 raw milk samples were collected from the milking bucket before and after implementing milking practices. The CFU count before and after implementing milking practices ranged from 2.7 - 6.1x108cfu/mL and 1.4 - 4.5x108cfu/mL, there was significant (P<0.05) reduction in the CFU count. Distribution on bacterial pathogens were,Escherichia coli (22%), Staphylococcus aureus (23%), Salmonella spp (21%), other members of Enterobacteriaceae family (21%)and Coagulase Negative Staphylococcus (CONS) (12%). Number of isolates before and after implementing milking practices were 24 and 8 (Farm A), 22 and 7 (Farm B), 27 and 7 (Farm C), 24 and 7 (Farm D) and 24 and 5 (Farm E) respectively.Questionnaire survey on milking practices Farm A and B scored (20%) while C, D, E scored (0%). On hygienic practices Farm A and B was (60%), C and D was (20%) while Farm E was (40%). Finally, the economic cost for implementing milking practices was N176 per milking per cow. It’s recommended to implement milking practices for production of quality milk.
