Archer, J.A. (2006) How valuable is selection for early calving?
Genetics is often seen as the key to early calving by farmers, and some of the recent research is confirming that Eastern deer do have significantly earlier conception than English genotypes.
But just how valuable is earlier calving? The major benefits proposed from earlier calving are associated with better aligning production with market demand (and so obtaining premiums for animals killed at peak schedule) and with seasonal growth patterns (thereby utilising grass more efficiently).
It should not be assumed that early calving will automatically produce a better fit between pasture growth and animal demand. It is likely that properties with longer winters and later springs will not be as suited to early calving as those with good early spring growth. In the limited scenarios examined, the financial outcome from meeting the spring schedule produced a more profitable outcome even when the alignment between feed supply and demand has not been improved by early calving

Results of studies on the hybridisation of farmed wapiti and red deer demonstrate that the use of wapiti sires over large red hinds can maximise the birth weight of calf producable and rearable by a red hind

Hybrids between Pere David's and red deer have been used as a tool for the rapid identification of genome regions (QTL) associated with production traits in deer. The ultimate aim of this technology is to develop a simple DNA test which can rank animals on genetic merit for a specific trait
