10 Global approach Relation between gross margin/ cow and CI

11 Global approach Relation between gross margin/ cow and CI = total production (milk and meat) – variable costs (herd and feeding) = total production (milk and meat) – variable costs (herd and feeding)

12 Global approach Relation between gross margin/ cow and CI = total production (milk and meat) – variable costs (herd and feeding) = total production (milk and meat) – variable costs (herd and feeding)

13 Global approach Relation between gross margin/ cow and CI = total production (milk and meat) – variable costs (herd and feeding) = total production (milk and meat) – variable costs (herd and feeding) Not ONE economic optimum of CI  Several economic optimum of CI, depending on the farm?

14 Typological approach Study of the relation between the economic results and the CI in groups of farms showing the same typology

15 Which typology? Study of the relation between the economic results and the CI in groups of farms showing the same typology Typological variables

17 Which typology? Study of the relation between the economic results and the CI in groups of farms showing the same typology Ares of corn silage (CS)/ livestock unit (LU) Ares of grass/ LU Typological variables

18 Which typology? Study of the relation between the economic results and the CI in groups of farms showing the same typology Ares of corn silage (CS)/ livestock unit (LU) Ares of grass/ LU Concentrate / cow Typological variables

19 Qualitative typological variables Which typology? Study of the relation between the economic results and the CI in groups of farms showing the same typology Ares of corn silage (CS)/ livestock unit (LU) Ares of grass/ LU Concentrate / cow Numerical classification

41 Why ? Longer voluntary waiting period (10 weeks vs 6 weeks) = economically optimum under some conditions (Inchaisri et al., 2011):

42 Why ? Longer voluntary waiting period (10 weeks vs 6 weeks) = economically optimum under some conditions (Inchaisri et al., 2011): -No Holstein-Friesian breed In the dataset used : Intensive group Less intensive group Intensive group without CS Extensive group % herds in the group with Hostein as main breed 92916762

43 Why ? Longer voluntary waiting period (10 weeks vs 6 weeks) = economically optimum under some conditions (Inchaisri et al., 2011): -No Holstein-Friesian breed -Low herd milk production

45 Why ? Longer voluntary waiting period (10 weeks vs 6 weeks) = economically optimum under some conditions (Inchaisri et al., 2011): -No Holstein-Friesian breed -Low herd milk production -High milk persistency

46 Why ? Longer voluntary waiting period (10 weeks vs 6 weeks) = economically optimum under some conditions (Inchaisri et al., 2011): -No Holstein-Friesian breed -Low herd milk production -High milk persistency Better persistency (670 days in milk (DIM)) for cows pasture fed (daily dietary intake 160 MJ of ME/cow) >< total mixed ration (TMR) fed (Grainger et al., 2009)

51 Limits on the current research and further analyses -Information per herd  averaged information  low tendencies observed -Future research  information per cow -explain the present results (persistency)

52 Limits on the current research and further analyses -Information per herd  averaged information  low tendencies observed -Future research  information per cow -explain the present results (persistency) -confirm the low tendencies observed

53 Limits on the current research and further analyses -Information per herd  averaged information  low tendencies observed -Future research  information per cow -explain the present results (persistency) -confirm the low tendencies observed  identify CI objectives for dairy farmers
