Socioeconomic and technical assistance factors related to total bacteria count and somatic cell count of milk from bulk tanks in southern Minas Gerais State, Brazil
The purpose of this survey was to evaluate the socioeconomic and technical assistance profiles of dairy farmers from six districts in the south of Minas Gerais state, Brazil, and to identify the possible risk factors associated with total milk bacteria count (TBC) above 43,000 CFU mL-1 and bulk milk somatic cell count (BMSCC) above 595,000 cells mL-1. Most of the producers were between 41 and 60 years of age (48.9%), 74.2% did not reach high school, and 72.3% of the respondents were satisfied with their profession, although 63% would not recommend dairy farming to their children. Only 34.7% used periodic technical assistance, but 59.1% consulted it in cases of doubt. The risk factors found in the final multivariable regression models were: TBC (Did not consult technical assistance in case of doubt, OR 3.97, P=0.030; Retirement, OR 9.32, P=0.041) and BMSCC (Producer does not reside on farm, OR 4.06, P=0.046; Presence of technical assistance OR 3.29, P=0.041). It can be concluded that the search for emergency technical assistance, as reported by farmers, was effective against the TBC problems; however, it was ineffective for controlling mastitis in the herd and reducing BMSCC levels. The 10 step mastitis control program from the National Mastitis Council needs to be included on the surveyed farms, especially the permanent advisory technical assistance from veterinarians, aiming towards the establishment of goals for udder health status, reviews and records.
