Effect of sensor systems on production, health, reproduction and economic results of Dutch dairy farms

  1. 1. Effect of sensor systems on production, udder health, reproduction and economics on Dutch dairy farms Wilma Steeneveld, Hans Vernooij and Henk Hogeveen
  2. 2. Sensors on dairy farms  Theory: Improve oestrus and disease detection ● Effect in practise on health and reproduction?  Reasons for investing were reducing labour and easing management (Steeneveld and Hogeveen, 2015) ● Effect in practise on labour costs and economic performance of the farm?
  3. 3. Objectives of the research  Investigate effect of sensors on ● Milk production ● Udder health (somatic cell count) ● Reproduction (days to first service)  Investigate impact of investment in sensors on costs and revenues on the farm
  4. 4. Available data 512 Dutch farms completed questionnaire about sensor use in 2013 (31% response rate) ● 414 farms with data on production, udder health and reproduction of the years 2003-2013 ● 152 with sensors, 262 without sensors ● 217 farms with accounting data of the years 2008- 2013 ● 54 with sensors on AMS ● 36 with sensors on CMS ● 127 without sensors Steeneveld et al., 2015, J. Dairy Sci. Steeneveld & Hogeveen, 2015, J. Dairy Sci
  5. 5. Sensor systems in use (%; n=152) 103 AMS farms 49 CMS farms Electrical conductivity sensor 98 41 Colour sensor 62 2 Somatic cell count sensor 15 0 Lactate dehydrogenase (LDH) sensor 2 2 Activity meters or pedometers for dairy cows 46 94 Progesterone sensor 1 2 Milk temperature sensor 50 6 Weighing platform 31 6 Fat and protein sensor 22 0 Rumination activity sensor 11 20 Temperature sensor 6 18 Beta-hydroxybutyrate (BHB) sensor 2 2 Urea sensor 1 2 Other sensor systems 4 8 Activity meters or pedometers for young stock 13 35
  6. 6. The herds No sensor AMS Before After CMS Before After No. of cows 85 83 102 106 141 Growth in herd size (%) 3.4 2.8 4.5 4.2 7.1
  7. 7. Analyses on milk, udder health and reproduction  Milk ● Dependent: average yearly production per cow ● Independent: year, % growth in herd size, sensors in use (0/1)  Udder health ● Dependent: average somatic cell count ● Independent: year, % growth in herd size, sensors in use for mastitis detection (0/1)  Reproduction ● Dependent: average days to first service ● Independent: year, % growth in herd size, sensors in use for oestrus detection (0/1)

  11. 11. Accounting data Capital costs • Fuel • Expenses on buildings • Depreciation on buildings • Expenses on machinery • Depreciation on machinery Variable costs • Roughage • Concentrates • Substitutes for concentrates • Milk powder • Minerals • Fertilizer • Pesticides • Breeding • Health care • Energy and water • Manure removal • Miscellaneous Labour costs • Contract work • Paid labour • Own labour Revenues • Milk • Livestock • Other farm activities • Miscellaneous FTE * 52 weeks * 40 hours a week * hourly rate
  12. 12. Economic results (€/100 kg milk) No sensor AMS Before After CMS Before After Capital costs 11.28 10.49a 15.08b 11.97c 12.34c Labour costs 12.38 11.69a 11.30a 11.30c 10.43c Variable costs 18.55 17.89a 18.69a 17.39c 18.25c Revenues 46.28 43.93a 46.38b 45.77c 47.18c Profit 4.07 3.86a 1.31b 5.11c 6.16c
  13. 13. Discussion  Decreased milk production on CMS farms ● Probably due to another major change at the farm  Higher SCC on AMS farms, and lower SCC on CMS farms after investment  No effect on labour costs ● FTE not a good measure
  14. 14. Conclusions  Lower SCC after investment in mastitis detection sensors on CMS farms ● Higher SCC on AMS farms  Having oestrus detection sensors did not improve reproduction performance  Capital costs increased after investment on AMS farms  No effect on labour costs observed
