Aubrac cattle are especially outstanding in their reproductive capacity, which is consistent regardless of the environmental conditions.

The breed reproduction qualities guarantee one calf per cow per year to the operation, without a problem. This is, in effect, the principle component of income.

Interval between births (IVV)

Some average statistics:

IVV average: 382 days (average taken for 37,116 cows)
IVV cows in second birth: 394 days (for 34,705 cows)
IVV cows with more than two births: 375 days ( for 30,207 cows)

Additional information:

The 41,941 cattle controlled within the framework of the control of features (Bovin Croissance) show a twinning rate in the Aubrac breed of 2.3%. The fertility rate is therefore 102.3%.

The Official data from the Institute of Cattle Raising and the follow-up organizations for the stations (Departmental Establishment for Cattle Raising-EDE and Bovin Croissance) gave the following percentages for the Aubrac breed (for 40,335 cattle controlled):

1% of the cattle were between 1.5 and 2.5 years old.
17% of the cattle were between 2.5 and 3.5 years old.

It can therefore be concluded that the renewal rate is approximately 18%.
