1 Changes in animal performance and profitability of Holstein dairy operations after introduction of crossbreeding with Montbéliarde, Normande, and Scandinavian Red  C. Dezetter, N. Bareille, D. Billon, C. Côrtes, C. Lechartier, H. Seegers  Journal of Dairy Science  Volume 100, Issue 10, Pages (October 2017) DOI: /jds Copyright © 2017 American Dairy Science Association Terms and Conditions

2 Figure 1 Generations of genotypes of cows at the end of the year for the 3 crossbreeding schemes simulated (a) and blood percentage in the herd for HO × MO scheme (b), HO × MO × NO scheme (c), and HO × MO × SR scheme (d) under an objective of constant number of cows over time. HO = Holstein cows; F1 = first-generation crossbred cows; G2 = second-generation crossbred cows; G3 = third-generation crossbred cows; G4 = fourth and following generation crossbred cows; %HO = percentage of Holstein blood; %MO = percentage of Montbéliarde blood; %NO = percentage of Normande blood; %SR = percentage of Scandinavian Red blood; (I) = initial state of the herd at the beginning of the simulation.

3 Figure 2 Mean for milk yield per cow-year, milk fat content and protein content according to breeding schemes, and levels in prevalence of health and reproductive disorders under an objective of constant number of cows (SE were between 4.4 and 11.4 L for milk yield per cow-year, and g/kg for fat content, and 0.13 g/kg for protein content). HO = pure breeding Holstein; HO × MO = 2-breed crossbreeding scheme with Holstein and Montbéliarde breeds; HO × MO × NO = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Normande breeds; HO × MO × SR = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Scandinavian Red breeds; (I) = initial state of the herd at the beginning of the simulation.

4 Figure 3 Mean for conception rate, incidence density of clinical mastitis, and number of events requiring manipulation of cows according to breeding schemes and levels in prevalence of health and reproductive disorders under an objective of constant number of cows (SE were between 0.16 and 0.20% for conception rate, 0.4 and 0.8 cases of mastitis detected per 100 cows, 0.01 and 0.02 events requiring manipulation of cows). HO = pure breeding Holstein; HO × MO = 2-breed crossbreeding scheme with Holstein and Montbéliarde breeds; HO × MO × NO = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Normande breeds; HO × MO × SR = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Scandinavian Red breeds; (I) = initial state of the herd at the beginning of the simulation. The number of events requiring manipulation of cows was computed as an occurrence counter for AI, treatments for mastitis or infertility, and calving events.

5 Figure 4 Mean for number of culled cows per 100 cow-years according to breeding schemes and levels in prevalence of health and reproductive disorders under an objective of constant number of cows or volume of milk sold (SE were between 0.16 and 0.35%). HO = pure breeding Holstein; HO × MO = 2-breed crossbreeding scheme with Holstein and Montbéliarde breeds; HO × MO × NO = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Normande breeds; HO × MO × SR = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Scandinavian Red breeds; (I) = initial state of the herd at the beginning of the simulation.

6 Figure 5 Average deviation of milk selling price (€/1,000 L of milk) of crossbreeding schemes compared with pure Holstein scheme according to prevalence of disorders under the objective of constant number of cows (—) and constant volume of milk sold (- - -). HO × MO = 2-breed crossbreeding scheme with Holstein and Montbéliarde breeds; HO × MO × NO = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Normande breeds; HO × MO × SR = 3-breed crossbreeding scheme with Holstein, Montbéliarde, and Scandinavian Red breeds.

7 Figure A1 Diagram of the reproductive processes: consecutive states for heifers from first breeding to calving and for cows between 2 calvings. A diamond represents a length between 2 consecutive events. A box represents a probability of occurrence for normal or abnormal events occurring during a reproductive cycle. DOC1 = number of days from calving to first ovulation; LOC = length of ovarian cycle in days; LG = length of gestation; PAO = probability of anovulation after calving; PDC12 = probability of delayed first and second ovarian cycles; PEB = probability that a cow ovulates without associated estrus behavior; PED = probability of estrus detection by the farmer; PCC = probability of conception for cows; PCH = probability of conception for heifers; PEED = probability of early embryonic death; PLED = probability of late embryonic death; PFD = probability of fetal death; PFC = probability of fertilization for cows; PFH = probability of fertilization for heifers.

8 Figure A2 Probability of fertilization according to DIM and producing ability for milk yield for cows in parity 1 to 3. Probability of fertilization does not take into account the producing ability of cows for fertilization and the effect of sire of bull (for Holstein cows bred with Montbéliarde sires) and assumes that the number of previous estrus cycles is superior to 1 and the current estrus cycle is normal.

9 Figure B1 Probability of IMI occurrence according to DIM and producing ability for milk yield for cows in parity 1 to 3. Probability of IMI occurrence does not take into account the producing ability of cows for mastitis susceptibility and the multiplicative factors for herd-level prevention, for current or previous IMI in the same cow and for contagion between cows.

10 Figure C1 Daily milk yield according to DIM and producing ability for milk yield for cows in parity 1 to 3. Daily milk yields were computed assuming that duration of dry period was normal (equal to 60 d) and cows were pregnant at 8 mo after calving and did not abort.
