Miniature Herefords were developed  by the Largent family in West Texas, USA starting in the 1970s.    Their reasoning was that the typical Hereford was getting too big, developing  too much bone and becoming harder on pasture and facilities.    In order to “downsize” the Largents used the smallest Herefords  they could find and continued to breed smaller over the decades until  they reached the size now called “miniature”.   For this  they are measured across the spine at the hip bones as the height there  is less likely to change than at the wither.  In general bulls  should be under 124cm and cows under 119 cm at three years of age to  be considered miniature.  These smaller animals are not a separate  breed.   They are descendants of the original Herefords brought  to North America in 1831 and their pedigrees trace back along the same  lines to those in the United Kingdom where the breed originated.    In conformation they should look exactly like the bigger cattle but  proportionately smaller.   
The characteristics of Herefords  are that they are efficient foragers, mature early, calve easily, milk  well for their calves and are excellent mothers.    They are extremely hardy and adapt well to almost any environment.    Their docile temperament and ease of handling makes them even more popular  as a breed.   Miniature Herefords are all of the above but  they have some added advantages.   They eat approximately  40% less food than their bigger cousins but produce 60% by weight of  the prime cuts with less bone.   It is possible to graze two  to three minis in the place of one larger animal yet get up to 25% more  beef and at the same time have less damage to pasture and facilities.

For those wanting to invest  in Miniature Herefords it is wise to look at the size of your property  before deciding on how many you want and whether or not you wish to  run a bull as well.   Cost will also come into it as with  so few Miniature Herefords in New Zealand they are not cheap.    It is probably best to start with just a couple of in-calf cows and  add  a  weaner heifer calf or two if you have the room.    A ten acre block would hold those easily and give you scope for some  expansion of the herd.   
On a small block of land it  would be better not to purchase a bull but to consider AI (artificial  insemination) or leasing one for the short time needed to get your cows  in calf again.   You would also need to look at selling stock  either when calves are weaned or using heifers to replace older cows  and selling the cows to avoid becoming overstocked depending on your  acreage.   Remember that winter usually requires supplementary  feed e.g. hay and drought conditions in summer could need it too.    Division of paddocks to enable rotational grazing is essential as set  stocking can lead to problems such as a build up of worm burdens especially  if you are not cross-grazing with other animals such as sheep.    This could also enable any surplus grass to be cut for silage or hay  in late spring or during summer.
If buying in-calf cows find  out all you can about when they are due to calve and locate a good vet  to be on stand-by especially if you have never had this experience before.    Calves will require vaccinations, there will also be dehorning and possibly  castration of bull calves not needed for breeding.   If wanting  animals for the freezer then sourcing a good Home Kill butcher is worthwhile.    If all this sounds daunting just remember there are plenty of experienced  people around only too willing to help you.

Should you decide to become  a registered breeder there are procedures to go through for which you  will be assisted.    Although you need to learn all you  can about your cattle and how you would like to develop your breeding  programme for matters like checking pedigrees in order to match your  cows with specific bulls, what time of the year suits you best for calving,  where and how you can sell or buy stock and so on there is always help  available.    This can be through the NZ Miniature Hereford  Breeders or other Breeders groups as well as working with vets, AI technicians,  Livestock Agents and other personnel connected with cattle breeding.    You do not have to go it alone.
