  3. Fromwhere ?

  4. Temperature(Quebec) °C

  5. MISSION Unite industry stakeholdersin improving the efficiency and profitability of dairy farms by stimulating the development of knowledge, facilitating its diffusion, and encouraging its adoption by dairy producers. Mr. Pierre Lampron, dairy producer President of FPLQ and Valacta

  6. Structure • Limited partnership • Board: 14 members • Majority are producers

  10. The largest dairy laboratory in North America

  11. Research & Development Multidisciplinary team Nutrition, Genetics, Comfort and welfare, Agroeconomist, Veterinarian, Goat milk production, Organic milk production, Data analysis and Knowledge transfer.

  12. What do cowsneed?

  13. Whatdo cowsneed? • Water and feeding • Space • Rest • Air • Light

  14. Feeding

  15. Non-dietary factors and herd performance (Bach et al., 2008) • 47 herds with similar genetics were fed same TMR • Milk yield varied by ±13 kg/d • Mean milk yield = 29.5 kg/d • Non-dietary factors accounted for 56% of variation in milk yield • Age at first calving • Feeding for refusals (29.0 vs 27.5 kg/d) • Feed push-ups (29.9 vs25 kg/d) • Stalls:cow

  16. Bunkspace • Reducecompetition • 60 cm (Lactating) • 75-90 cm (Dry-Transition)

  17. Water

  18. Water • Min 2 troughs/group • 60 cm per 15-20 cows. • 60 cm/head (exit of the parlor) Position: Externalwall

  19. Is it correct ?

  20. Resting

  21. Relationship between resting and milk yield(Miner Institute data base) • Increased resting time with greater DIM, milk yield (Bach et al., 2010) 49 45 Milk yield (kg/d) 41 ~1.7 kg/d more milk for each extra hour 36 32 y = 22.3 + 1.7 x r2 = 0.31 27 7 10 13 17 Resting time (h) (Grant, 2010)

  22. Cows have strong behavioral need to rest … • Cows sacrifice feeding to make up lost resting • For every 3.5 min of lost rest, cows sacrifice 1 min of eating • Cows spend more time waiting in alleys to lie down than eating when overstocked • Negative effects of short periods of deprivation are cumulative Resting: 12-14 h/d “Vitamin R” Grant, 2010

  23. Resting time • Minimum 12 h/d • To promoteresting time: • Stallwidth • Soft surface

  27. Stalls per cow and milk production in 47 herds fed same TMR (Bach et al., 2008) Milk yield = 20.4 + 7.5 x stall/cow R2=0.32 1.5 kg Grant, 2010

  37. Stall design C = Length from rear curb to neck rail 23 cm max Maintain neck rail at 110 to 130 cm above bedding surface B= Divider mounting width 30 cm max from stall surface to top of lower divider rail 12 cm Minimum sand depth at Max fill: 30 cm Minimum sand depth before fill : 15 cm 20 cm high curb A = Length from rear curb to brisket locator Stall length 300 cm against a side wall , 275 cm Head to head

  38. Sand -More milkthanmattresses or strawbedding. -Less injuries -Liying time isbetter But : -Manutention -Granulométrie Test de la poignée Vortex Holsteins

  39. Matresses/bedding La litière est toujours obligatoire… pour réduire l’abrasion
