Abstract

This study identified the association of management practices and herd characteristics with milk quality of bulk tanks in southeastern, Brazil. Milk samples were collected weekly during 8weeks from 63 dairy herds. Bulk tanks were evaluated for total bacteria (TBC), preliminary incubation (PIC), pasteurization (PC), coliform (CC), and somatic cell counts (SCC). Associations found were type of milking system utilized in the farm with TBC, PIC, and SCC; the use of gloves for milking with TBC and PIC; sanitation of milking equipment prior to milking with PC and CC; strip cup testing of cows with PC; teat washing prior to milking with SCC; pre-milking teat disinfection with TBC and CC; post-dipping with TBC and SCC; and the alkaline-acid washing procedure of milking equipment with PIC and PC. The regression analysis explained the variation of bulk tank PC (-0.47 log cfu/mL) due to the adoption of strip cup test (P=0.036) and, by 0.366 log cfu/mL due to alkaline and acid washing of milking equipment (P=0.036). Herringbone milking systems adopted on farms represented a change of -0.11 log cfu/mL on the log SCC (P=0.048). Findings may provide a guideline to prioritize efforts aimed at improving milk quality at the farm level in Brazil. (AU)
