Re: Ayrshire, Red catle, SRB


the Norwegians decided back in the 60ties 70ties sometimes, to start mixing all the dairy breeds they had into one.
this new "breed" was named NRF, now here's a bunch of mongrels made up from friesians, a variety of red breeds and polled mountain cattle. They also have used a few Swedish friesian bulls as sires of sons.
If you use NRF you have know idea what you're going to get, the resulting offspring could be any shape, size or colour.
To me a real breed has certain recognisable characteristics, such that makes it easy to tell a Jersey from a Brown Swiss or a Holstein from a Guernsey.
With the NRF you don't know if you have a goat or a buffalo or anything in between.

Let Charity loose with their paperwork.

I'm sure he could tell you exactly what to expect from each mating.

Re: Ayrshire, Red catle, SRB


The Norwegian Red (NRF) has a history back to the 30s. THe breed is based on Ayrshires, Shorthorns, Swedish Red and old Norwegian breeds. In the 70s and the 80s some Swedish Friesian and Holstein sires were used. Friesian and Holstein genes account for about 20% of the composition of the breed. Since 1997 Holstein sires are no longer used. Because of the backgrouind about 30% of the individuals are black and white. Otherwise the breed is as uniform as any other breed with a low inbreeding rate.
The specialities of the breed today are high fertility, high mastitis resistance, high milk yield and also a high (around 25%) proportion polled animals.

Re: Ayrshire, Red catle, SRB


Is it true that the Scandinavian Red Breeds are prone to milk fever?

What is the incidence of milk fever like in the red breeds compared to the Jersey and Holstein breeds?

Is there a difference in milk fever incidence between the Swedish and Norwegian strains?

It used to be the case that they where more prone to milk fever than Holsteins but today the difference is neglectable.
unfortunately I have no current % on it.
I'm not aware of any difference between NRF and SRB

Thanks Broa. Which SRB bulls do you use? What do you think of Jurist, Peterslund and Lars?

Re: Ayrshire, Red catle, SRB


at the moment I'm using Orraryd, Peterslund and Jurist for all of our TEN reds emoticon
I wouldn't use Lars due to high pins.
I have only two cows out of 100 that have high pins and one of them I just bought from a friend since she'd become unmanageable in his system, all the rest of my cows have nice sloping rumps because that's the way they've been bred.
I never liked to sacrifice a good rump for the sake of production or high rear udders.
my AI technician tells me there's high pins everywhere these days and that it is unusual
with only 2 in a herd.

Re: Ayrshire, Red catle, SRB


As far as I know the Illawara is a strain of Shorthorn. (Scroll down these threads and you will find one where Foxleigh elaborates on the Illawara)

The Aussie Red's major influences are the Swedish Red. They also list Swedish Red bulls in their rankings.

The number two Illawara bull has Backgard in his name, so I take it he is a son, Backgard is an SRB. So maybe there is a little bit of cross pollination going on there. emoticon
