"A FINN-ANCIAL SUCCESS STORY
In this issue I would like to summarise an article from the New Zealand
Meat Producer, Last Quarter, 1996 entitled Managing High Performance. It
concerns the success of Andy and Hamish Ramsden of Tararau who have dramatically
lifted their lambing percentages from the loss-making NZ average of 115%
in 1990 to a very profitable 169-194% using Finn-Friesian genetics.
The Ramsdens changed from pure Romneys to Finn-Romney crosses. In 1996 their
hoggets averaged 87% at marking, their two year olds 169% and their three
and four year olds 194%. Andy says, “The Finn’s given us the ability to improve
the lambing percentage and put selection pressure on, delivering twins and
triplets with ease. The East Friesian completes the picture by adding mothering
ability and fast growth, and makes it possible to finish lambs to slaughter
on mother’s milk.”
They have also produced 2136 half-Friesian lambs from their Finn-Romneys
(by AI @ 178%) which averaged 24 kg at two months old, “Ultimately I want
a ewe that is half-Finn for fertility and feed conversion, a quarter East
Friesian to be a ‘milk machine’ and a quarter Romney for reliability,” Andy
says.
The Ramsden’s success is a combination of innovative genetics and excellent
feed management. (The feed level is adjusted by buying and selling cattle).
They believe in feeding ewes above maintenance levels while they are in lamb
and with lamb, getting the ewes back to within 3 kg of mating weight at docking,
and back to mating weight at weaning.1 Feeding the ewes and lambs well overcomes
the common criticism of the smallness of twins: We’re not getting smaller
lambs and it’s all what goes down the throat,” says Andy.
Using Finn-Romneys has led to a drop in micron from 39 to 34 and to a 10%
decline in wool weight which is more than made up for by the premium for
finer wool.
Andy finds the attitude that Finn sheep aren’t for everyone hard to understand.
“The best looking sheep is the one that’s the best performer - whatever that
might look like, he concludes." Sheepnotes Winter 1997.

"COWRA MATERNAL PROGENY TEST
As you may know NSW Agriculture has been conducting research into the qualitative
differences between both paternal and maternal sires. The results of the
latter are nearly complete and show a conclusive advantage of Texels over
Dorsets.
Preliminary results are available for the first-cross progeny of the maternal
sires. To know whether there is a conclusive difference among the various
maternal breeds we shall have to wait until the first draft of twelve month
old ewes lamb in about August of this year. We are confident that the Finns
will be proven to be superior to all other breeds in precocity and fertility
as this has been the result everywhere else in the world where similar research
has been carried out, Finnsheep having been the most studied sheep in the
world over the last fifteen years.
The preliminary results are very positive. The Finn sires produced a greater
rate of pregnacy (by AI) than all other breeds, (90.4% compared to 86.1%).
Our clients corroborate this: most farmers when crossing Finns and Merinos
report a leap in lambing percentages from @ 85% to @ 115%. The number of
lambs born at Cowra to the various breed showed the Finns averaged 13% better
than the Border Leicesters and 12% better than all other breeds.
If you take into account the percentage survival of twins and the level
of assisted births, the Finn performance was even better than this. Finns
lambs needed assistance in less than 4% of ewes, compared with Border Leicesters
at 11%, East Friesians at 19% and Suffolks at 15%. Twin survival amongst
Finn lambs was also superior: 79% compared to 74% for Borders, 72% for East
Friesians. Weight of lambs at weaning was not significantly different amongst
the breeds: Finns were just on average at 24.4 kg, Border Leicesters at 25kg
and East Friesians at 25.3kg. As the paternal sire study has shown though,
these slightly bigger lambs don’t contain more meat; the extra weight is
bone and fat, for which the producer is charged a penalty." SHEEPNOTES, SUMMER

FINNSHEEP:
BOOST MARGINS 1000% !
“Although multiple births do require more attention and care, the profits
seem well worth the effort. A 1987 Uni of Wisconsin analysis stated that
it would require 5,721 ewes producing one lamb each to generate a $25,000
profit, and only 353 ewes producing two lambs to equal it.”(Raising Sheep
the Modern Way, p12)
Clearly the value of lambs, and associated costs must be very different
in the USA, but the point about the value of twinning is well made. Agnote
No 430/22, June 1981 shows that only 3% of lambs need to be saved to cover
the costs of an intensive lamb raising enterprise - the rest is profit.
Agnote no 430/817 outlines gross margins for prime lamb production for 1981.
For 1,300 ewes , and 26 lambs with 95% of lambs sold to ewes joined, prime
lambs sold for $22, first-cross ewes purchased for $38, & cast for age
ewes sold for $15 (how times change!), the calculated margins are:
Income
Wool: @ 4.5 kg @ 215c $12,578
Livestock Trading $18,260
Total $30,949
Costs
Wool Harvesting $3,626
Sheep Husbandry $1,100
Supplementary Feeding $2,262
Interest on Livestock Cap. $4689
Total $11,677
Gross Margin $19,272
Doubling the percentage of lambs sold per ewe (to 190% - for convenience,
but this is normal for Finn cross ewes) adds $27,170 to the Livestock Trading
account and $26 354 to the Gross Margin, increasing it to $45,626 an increase
of 240%. If we add in interest on the farm (250,000 @ .08%, or $20,000) and
other farm costs @ say $10,000, you can easily see how an infusion of Finn
genes can increase the gross margin by 1,000% or more!" Sheepnotes, Winter
