Having been dissatisfied with
Breedplan for some time now, and after careful consideration we have decided
to end our association with this scheme. Because we have a closed herd, (a
move forced on us about 10 years ago because we wanted to maintain Pure NZ
bloodlines), Breedplan has become pretty well meaningless to us for several
reasons. Firstly Group Breedplan relies heavily on link sires to other herds
so that comparisons can be made. We breed all our own sires so that our herd
lacks these links. Interestingly though, when stud bulls we sell get out into
other herds, they perform well. A good example is the bull we sold to David
Giddens. Waimata I652 is now a trait leader for 200 day growth ! At +43 he is
well above the breed average of +31. His pedigree is Pure NZ i.e. no American
blood. Likewise the bull Waimata E230 when he went to Alistair Sharp’s
Waitawheta Stud he developed some impressive figures for a Pure NZ bull. +59
for 400 day growth, +82 for 600 day growth, +102 for Mature cow weight, and
+12 for milk. All these figures are above the breed average. Secondly
Breedplan seems to discount home bred sires in favour of imported sires.
Mindful of the need for some form of objective performance measure, we are
currently investigating DNA
tests for several traits including Tenderness, Marbling, and most
interestingly a gene marker test for feed conversion efficiency. As our cost of production is determined by the amount of feed consumed
by our cattle, this latter trait has very exciting possibilities for
identifying and breeding cattle which excel at converting grass to beef. I
suspect that feed conversion efficiency will be found to be linked to
constitution, something not measured by breedplan but so important if NZ is
going to take full advantage of the coming worldwide swing to grass fed beef. |

Although it’s early days, the prospect of being able
to test an amimal for economically important traits is an exciting concept.Unlike Breedplan where
predicitions about an animal’s breeding potential are calculated via a
complex computer programme, DNA marker tests simply determine if an animal
has the genes being tested for, or not. If it has they will be passed on to
the progeny. No guesses, no estimates simply 100% certainty. At present there
are tests available for 3 Traits, marbling, tenderness, and most importantly,
FEED CONVERSION EFFICIENCY. There is a big variation between animals in the
amount of feed consumed to put on a Kilo of beef. Here at Waimata Angus we
have spent the last 35 years selecting for 2 main traits, Constitution and Growth. We felt constitution had to be tied to feed
conversion ability.To test this theory we decided to subject 200 Heifers and
Bulls to the Genestar suit of tests.We have been extremely pleased with the
results which indicate a very high incidence of tenderness and feed conversion Genes. One
sire, a young son of Waimata Skytower, Waimata Skyline Sn 826 has an
impressive maximum 8 stars for tenderness, and 7/8 for feed conversion
efficiency. This is an exciting package, as the bull himself is a very
impressive animal. Great size combined with a superb temperament. He has been
to Tararua Breeding centre for collection. Skytower
continues to produce them. Waimata Skyhigh 228 is one
of the very rare bulls with 8/8 for tenderness AND 8/8
for Feed conversion efficiency. This is the bull that caught the attention of
Bill Doyle South Dakota on a recent visit. We have sold semen from this bull
to numerous studs in the USA & Canada, all expressing the desire to get
back to more feed efficient cattle. They are saying this the only way they
they can control their cost of production. There is a huge difference between animals in the amount of feed
required to put on a kilo of beef. When feed grain was cheap, efficiency wasn’t an
issue. Those days have gone forever. Here in NZ our costs half gone through
the roof as well. Here on Otonga
I don’t think we will ever get back to the days of putting on 300
tonnes of super each year. Pastures on the steep hills will inevitably
deteriorate and only cattle with fleshing and constitution will handle these
conditions. We have been told many times by clients that bulls they have
bought from us continue to grow and put on weight whereas bulls bought
elsewhere seldom regain their sale day weight. Waimata Angus cattle are bred
to thrive on hill country grass, and have been selected and bred from the
environment in which they are expected to perform. |
