I get what you are saying...

Two-breed rotation or criss-cross (Figure 1). Rotational systems involve a specific cyclical pattern of mating breeds of bulls to progeny resulting from a preceding cross. The simplest example of a rotational system is the two-breed rotation or criss-cross system.


Figure 1
Breeding scheme for a two-breed rotational crossbreeding system

A series of alternating backcrosses are used in the two-breed rotation. In a Hereford-Angus rotation, progeny resulting from an initial Hereford-Angus cross would be backcrossed to one of the parental breeds, say Angus. The resulting backcross progeny, 3/4 Angus and 1/4 Hereford, are mated to Hereford bulls. Progeny resulting from this third generation are mated to Angus bulls and this cyclical pattern continues.

After three generations, breed composition stabilizes at approximately 2/3 the breed of the sire and 1/3 the remaining breed. In this example, generation four calves are sired by an Angus bull and are approximately 2/3 Angus and 1/3 Hereford.

thats some interesting info van, thanks for sharing. i guess i never really thought too hard on it but i'm glad to know now. makes good sense

I think that if the sire is a fullblood limi he might be at a disadvantage. Try posting a picture though.

Why might that be?

The "fullbloods" lost alot of ground when most of the breeders went black.

So....I have a BLACK Limosin Cross.. What do you mean they lost alot of ground?

Is the sire of the calf black or red?

Ok that changes it. Disregard my earlier post.

Good Luck with your new calf and be sure to post pictures soon! ;-)

Maybe they're like me, and wonder how do you get a 1/3 x 1/3 x 1/3?

It's possible, but would be very unusual. If you bred a bull that was 2/3 Limi 1/3 Angus to a cow that was 2/3 Hereford 1/3 Angus, the calf would be 1/3 Limi 1/3 Hereford and 1/3 Angus. Well, I think so anyway. ;-)

I was busy trying to figure it out just to be a wise arse and you beat me to it ;-)

OK, just for fun, how do you get an animal 1/3 x 2/3? :lol:

Two-Breed Rotational Cross. In this system, bulls of two breeds are used. Females sired by a bull of a particular breed are mated to a bull of the other breed. Thus, after several generations, approximately two-thirds of the genetics of each calf result from the breed it was sired by, one-third from the other breed.

A guy down the road from me does it with Angus and Simmies. Pretty simple really. Only drawback is you need 2 breeding pastures (unless you AI), and you have to keep track of which cows were sired by which breed of bull.

Ummmm, no, that would be 3/4 and 1/4. As far as I know you can never get 1/3 when you are breeding 1/2's.

If you keep alternating the same two breeds you will.

Trev, if you want to do more in life than knowing how to grow great hair, like breeding & feeding a great calf under that hair, then yes, it really does matter! What you learn now will help you in your life. If you want to be a hairdresser then I guess you can concentrate on growing hair and don't worry about genetics, math, nutrition, etc.

Thanks... I have to delete some pics off my camera so I can take some of the steers. I found out yesterday that I get my sisters steer. Woot Woot. Another one to train... :lol: The is the same breed as the other one... But her has a white face... And then I am going to have a dairy steer too!
