2 What to expect? Mastitis from an economic perspective Costs of mastitis Farmers own estimation Benefits of improved management Conclusions

3 Economics of mastitis Dairy farm Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. After: McInerney, 1996

4 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction

5 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction Mastitis

6 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction 1. Lower efficiency Mastitis

7 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction 1. Lower efficiency 2. Lower suitability for processing Mastitis

8 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction 1. Lower efficiency 2. Lower suitability for processing 3. Less satisfaction Mastitis

9 Economics of mastitis Dairy farm Other input Capital Land Dairy processor Consumption Input Capital Buildings Equipment Feedstuffs Health care.. Land Output Main product Milk Side products Calves Meat.. Output Fresh milk Cheese Deserts Satisfaction 1. Lower efficiency 2. Lower suitability for processing 3. Less satisfaction 4. Lower societal value Mastitis

10 Effects Lower efficiency Lower suitability for processing Less satisfaction Lower societal value

11 What to expect? Mastitis from an economic perspective Costs of mastitis Farmers own estimation Benefits of improved management Conclusions

12 Cost of mastitis Default cost calculations Based on literature and expertise Clinical mastitis: Yearly incidence Subclinical mastitis: Bulk milk somatic cell count Conservative estimations Data collection 64 dairy farms Data entry at open farm days Assistance from researcher

13 Theory vs practise ( /cow/year) Default Production losses subclinical 16 Production losses clinical 23 Veterinarian ( /cow/year) Drugs Discarded milk 9 Culling Penalties Total economic losses

14 Theory vs practise ( /cow/year) Default Mean Farm specific Low High Production losses subclinical Production losses clinical Veterinarian ( /cow/year) Drugs Discarded milk Culling Penalties Total economic losses

15 What s behind this Farm specific Default Mean Low High Costs milk prod. losses ( /kg) Visit costs ( /visit) Drug costs ( /treatment) Value labour ( /hour) Culling costs ( /culled case)

16 Real vs expected costs (n=64) 200 Real costs ( /cow) good estimators Expected costs ( per cow)

17 Too high estimation 200 Real costs ( /cow) over estimators Expected costs ( per cow)

18 Too low estimation Real costs ( /cow) under estimators!!!!! Expected costs ( per cow)

19 What to expect? Mastitis from an economic perspective Costs of mastitis Farmers own estimation Benefits of improved management Conclusions

20 Costs alone are useless - Is there room for improvement? - 18 management measures (Huijps et al., 2010) -Quantify effect -436 scientific papers ( ) -43 relevant and useful - Expert sessions -Effect 100 % contagious -Effect 100 % environmental -Efffect on BMSCC -Efffect on clinical mastitis

21 Calculate benefits Current costs of mastitis - new costs of mastitis (with new effects) + costs management measures (labour and materials)

22 Average Farm characteristic Nr cows 65 Production (kg/cow/year) 8,500 % environmental mastitis 65 % contagious mastitis 35 BTSCC 200 Incidence of clinical mastitis (%) 30 Milking places in milking parlour 12 Costs of mastitis ( /farm/year) 4,743 Costs of mastitis ( /cow/year 73 Net benefits ( /cow/year) of management measure

23 Farm type Average Problem Good Farm characteristic Nr cows Production (kg/cow/year) 8,500 8,500 8,500 % environmental mastitis % contagious mastitis BTSCC Incidence of clinical mastitis (%) Milking places in milking parlour Costs of mastitis ( /farm/year) 4,743 7,199 1,405 Costs of mastitis ( /cow/year Net benefits ( /cow/year) of management measure Milking clinical last Milking subclinical last Separate cloth Wash dirty udder Prestripping Milkers gloves Dipping 0, Rinse clusters clinical Rinse clusters subclinical Replace teat cup liners Treatment protocol Drying off Keep cows standing Dry cow minerals -0,3 9-9 Overcrowding Clean boxes Clean yards Optimize feed

26 What to expect? Mastitis from an economic perspective Costs of mastitis Farmers own estimation Benefits of improved management Conclusions

27 In summary Mastitis costs money Mastitis is still expensive (farmers underestimate) Losses differ -> farm specific calculations Effectiveness of management Farm specific effectiveness Effect of measure depends on assumptions (dynamics)
