Beef Bull Sales
Beef breed performance comparisons
Charolais were the first exotic breed.
In the 1950s and 1960s the Department of Agriculture
began research into growth rates of beef cattle at
Ruakura Research Station, Hamilton, and at the nearby
Whatawhata Hill Country Research Station. They found
that growth rates are moderately to highly inheritable, so
farmers who measured their cattle's growth and bred
them selectively could considerably improve their herds.
By the mid-1960s, commercial bull-breeders began to
weigh and record animals during different stages of their
growth. In 1973 Beefplan, a centralised performance
recording scheme, was set up to compare animal
performance -- but the system was limited, as it could
only compare animals run together in the same
Estimated breeding values (EBVs), which predict an
animal's value as a parent compared with other potential
parents, enabled scientists and breeders to compare the
genetic potential of animals regardless of environmental
effects. Beef breeders can now use 17 different EBVs for
estimating productive traits, including fertility, growth
rates and carcass quality.
Cross-breeding has been a feature of cattle breeding in
New Zealand since the 1950s. One benefit is hybrid
vigour, where cross-bred offspring outperform their
Another system of cross-breeding deliberately combines
the best qualities of two or more breeds. Bulls of beef
breeds are mated with dairy-breed
cows, producing cross-bred cows with
superior milking and reproductive
ability. When these cows are mated to a
suitable terminal sire (a bull that breeds
animals for meat, not further breeding),
they produce calves with high growth
rates, which will have heavy carcasses.
For instance, a Hereford bull is used with
a Friesian cow to produce a cow that is
then mated to a terminal sire, such as a
Charolais, to breed calves that grow to
heavy slaughter weights.
When cattle weights began to be
recorded in the 1960s, it became
apparent that calves from European
breeds (known as exotic breeds) gained
weight much faster than British breeds.
They also grew to heavier mature
weights. European cattle were used as
draught animals up to the 1920s, so size
and bulk were important.
New Zealand beef breeders hoped to
use these large animals to improve the productivity of
traditional breeds. However, exotic cattle also had
problems -- calving difficulties and high feed
requirements. As a result, they did not replace Angus and
Hereford cattle in commercial herds. Instead they are
used almost exclusively as terminal sires (sires that breed
animals for meat, not further breeding).
The Charolais was the first exotic breed introduced into
New Zealand. It was developed in the Charolles district of
central France, where it was used as a draught animal and
noted for its meat quality. Charolais semen was imported
for trials at Lincoln and Ruakura in 1965, and by a
commercial farmer the following year.
Live cattle were later imported, resulting in a pure French
Charolais type. A 'New Zealand Charolais' has also been
developed by mating Angus or Hereford cows with
Charolais sires over five successive generations.
Charolais are large, muscular horned cattle with white or
very light straw-coloured coats. Their high growth rates
have made them popular as terminal sires for beef
The Simmental originated in western Switzerland, and is
the second most common cattle breed worldwide.
Although pure Simmental cattle make up only 1 per cent
of the New Zealand beef herd, the bulls are popular as
terminal sires, and are widely mated with Angus,
Hereford, and Angus--Hereford-cross cows.
The Simmental was initially bred for milking as well as
meat, and was used as a draught animal. Specialised
breeding in different countries has led to variations.
Generally, the Simmental is a large, well-muscled horned
cow. It is light straw to dark red in colour, with white
patches on the head, underside and legs, and often dark
patches around the eyes.
The cows have good maternal qualities and a good milk
yield, so they produce well-grown weaners. Simmentals
have excellent rates of growth and feed conversion -- they
turn more of their feed into meat than some breeds.
Limousin cattle arrived in New Zealand in the mid-1970s.
They have become popular for their hardiness, docility
and meat quality, and are widely used as terminal sires.
Limousin cattle are an ancient breed from the Massif
Central in France, where they had to cope with poor-
quality pasture. This ability has been passed down to the
modern breed. Originally a draught animal, they have
been used for meat production from the late
The modern Limousin is a medium-sized, well-
muscled animal with a rich golden-brown coat.
Limousins mature earlier than most European
breeds and are renowned for their high-quality
carcass, with a high meat-to-bone ratio.
Many breeds of beef cattle have been imported
into New Zealand since the 1960s, mostly from
Europe, but some from Australia, the US and
