The Need - Milk Safety and Quality
Every dairy operation must ensure that its milk is of high quality and safe for consumption. High quality milk is crucial for processing high quality dairy products.
Per regulations, milk displaying the following must be discarded:
- contamination by antibiotic residue and added water
- high temperature
- high DMC (Direct Microscopic Count) of bacteria
- inadequate sensory factors (smell, taste, visual)
Likewise, milk quality affects the product’s taste and shelf life, as well as the cost of manufacturing derivatives.
Parameters of milk quality:
- somatic cell count
- milk solids (fat, protein, lactose)
- mastitis pathogens (e-coli, staphylococcus)
While processing plants’ rejection of bulk milk shipments seriously affect dairy profitability, milk quality price premiums are great. These premiums provide good incentive to invest in the best control systems and management practices.
Achieving high quality milk is a joint effort of dairy managers and farm personnel. Milk quality is best controlled by proper milking routines that combine daily practices and training of milkers.
Dairies must observe the following:
- Contaminated milk – Prevention efforts must be made by dairy personnel. Antibiotics, colostrum, high SCC, clinical mastitis cows, etc., must be identified and milked out of the system.
- Cleaning system – A good CIP program for cleaning and disinfecting the milking system is critical.
- Milking system equipment – Milk tanks and milk cooling devices must be maintained.
- Milk components – Milk solids must be controlled and monitored in accordance with their destination, for example, to the cheese industry.
- Cross contamination – There should be no cross contamination between cows. Milking equipment must always be cleaned after the appearance of contaminated milk.
Afimilk provide a wide array of monitoring and control tools to prevent bulk tank contamination and maintain good quality milk.
For the dairy manager – Afimilk offers tools for decision-making, control and monitoring:
- a criteria-based selection of cows and milk rejection due to antibiotics, high SCC and colostrum
- automatic assignment of milk rejection code options according to criteria
- milking equipment malfunction alerts, which enable on-time corrections
- wash monitoring module that alerts users to CIP failures
In the milking parlor – alerts for milk rejection, as well as automatic milk rejection options enable:
- various alert levels according to manager-selected criteria
- automatic removal of cluster if blood is detected
- different options for automatic separation of contaminated milk:
- high SCC – first milk or complete milking of selected cows
- colostrum, antibiotics or other criteria
- per destination, for example, high solids for cheese, low solids for raw milk
