Reproduction

Reproduction

Reproductive productivity of the breeding herd is central to productivity to deer farming in New Zealand.  Reproductive performance has been limiting potential on many farms for many years.  The following topics will help you assess the components of reproductive productivity and performance.

A growing library of convenient DINZ Deer Fact sheets on environmental subjects is being published as part of the P2P programme. 

-  Best practice mating management
-  Setting reproduction targets

Effect of photoperiod (day length) on breeding

Seasonality in deer is regulated by day length, technically known as 'photoperiod'

Hinds

For most deer farms, the reproductive performance of hinds on the breeding unit is the key measure of on-farm productivity and profitability. Good hind management is essential for ensuring the best performance of the herd.

Calving

Farmed red deer and wapiti crossbreds in NZ calve in early summer, from late October to early December. Most hinds within the herd will complete calving within a 3-week period, although there will typically be a few hinds conceiving at later oestrous cycles that calve over the next few weeks.

Stags

Stags are an important part of the mating programme on all farms.They must be well managed and in good condition at the beginning of the rut sot hey can perform to the best of their abilities.

Foetal wastage

Abortion of the foetus before due date.

Artificial breeding

Artificial Insemination (AI) and Embryo Transfer (ET) are well-established, viable and practical tools to improve rates of genetic gain within the NZ deer farming industry.
