In the Ivalo herding cooperative, the cumulative thickness of the snow cover (Dec, Jan, Feb, March) and the calving percentage were significantly related ([r.sup.2] = 0.119, p = 0.046, df = 33), but in the Hammastunturi herding cooperative, the relationship between snow cover and the calving percentage during the same period was not clear ([r.sup.2] = 0.049, p = 0.206, df = 33) (Fig.
After the 1980s, the calving percentage decreased in the siida of Kuttura (Fig.
Snowmelt onset and the calving percentage were negatively related: the earlier the onset of snowmelt, the higher the calving percentage ([r.sup.2] = 0.130-0.218, p = 0.005-0.026) (Fig.
However, if there was a 10% lift in the calving percentage, there could be another 46,387 calves on the ground each year without any rise in cow numbers and 15 to 24 months after that numbers moving through abattoirs would increase, too.
For example, both herd health and nutrition programs directly influence calving percentages. Adequate nutrition is vital for a breeding herd, since cows in poor condition are not likely to conceive.
