What are the returns on investment in mastitis control?

When dollars are scarce, the management decisions made on farm come under even more scrutiny.  Where should money be spent and what are the likely gains from these decisions?  The mastitis control strategy adopted on your farm is on-going, but have you ever wondered what the investment is really worth to you? 

Over the last year Countdown Downunder has looked at the dollars associated with mastitis control. Their latest modelling work estimates and compares figures for different farm strategies.

Dollars are gained from better udder health because there is more milk (higher production and less discarded) and it is sold at higher prices. There are fewer cows that require treatments and fewer cows to cull because of mastitis. To achieve this some dollars are spent on preventing infections. The outcome of investment in mastitis control must be assessed with all these factors calculated over a period of time – not just the cost of a particular consumable, or the milk price for a particular cell count level.

Countdown’s research shows that Australian herds can achieve net gains with lower annual average Bulk Milk Cell Counts  – right down to very low figures.

The annual average Bulk Milk Cell Count is the average of all the BMCCs for a whole year. This gives an indication of the mastitis control for the herd over a relatively long time frame that can be assessed economically. 

The example below shows the dollar differences for farms with different mastitis prevention strategies. 

 

How much money are we likely to make from investing in mastitis control?

Net returns (benefits after costs are deducted) for split-calving herds achieving different average Bulk Milk Cell Counts over a twelve month period.

Annual average BMCC                            Additional dollars per cow per year

90,000 compared to 150,000 cells/mL      $24 per cow per year

150,000 compared to 250,000                 $47

250,000 compared to 350,000                 $55

350,000 compared to 450,000                 $118

The additional dollars for each step can be added. For example the difference between herds averaging 90,000 cells/mL and herds averaging 250,000 cells/mL is $71 per cow per year.
