breed % math help

[Dee]

I have asked a few others, evidently math is not anyones strong point around here. So....
If I have 1/2 Hereford X 1/2 Angus cows, breed them to Angus, their calves are ??? 5/8 Angus X 3/8 Hereford (right?) Then breed their calves back to Angus, then they would be __ Angus X ___ Hereford, and the next generation would be ????

So, starting with the F-1, what % are the next generations, if I keep breeding to Angus?

Your answer is 3/4 and 1/4.

Slowly but surely breeding out the hereford influence.

1/2 hereford x 1/2 angus bred to 100% angus will yield a 3/4 angus x 1/4 hereford calf. Take that calf and breed to a 100% angus and you will get a 7/8 angus x 1/8 hereford calf. Breed that calf to a 100% angus and you will get a 15/16 angus x 1/16 hereford calf. Might as well be a full blood angus after that point. Anyone please feel free to correct my math if I am wrong - it is early in the morn....

1/2 hereford x 1/2 angus bred to 100% angus will yield a 3/4 angus x 1/4 hereford calf. Take that calf and breed to a 100% angus and you will get a 7/8 angus x 1/8 hereford calf. Breed that calf to a 100% angus and you will get a 15/16 angus x 1/16 hereford calf. Might as well be a full blood angus after that point.

That was the way I have always been told.

1/2 hereford x 1/2 angus bred to 100% angus will yield a 3/4 angus x 1/4 hereford calf. Take that calf and breed to a 100% angus and you will get a 7/8 angus x 1/8 hereford calf. Breed that calf to a 100% angus and you will get a 15/16 angus x 1/16 hereford calf. Might as well be a full blood angus after that point.

Sidney411, my math matches yours exactly.

In the original description, 5/8 and 3/8 are wrong. It should be 3/4 and 1/4 and is not good for my climate.

The 5th cross is 31/32 and deemed "pure" by many standards.

I don't know where you're headed with these cattle, but you should be aware that the Angus Assn will not register any percentage animal. At least right now. They are looking into starting a separate registry for percentage animals.

1/2 hereford x 1/2 angus bred to 100% angus will yield a 3/4 angus x 1/4 hereford calf. Take that calf and breed to a 100% angus and you will get a 7/8 angus x 1/8 hereford calf. Breed that calf to a 100% angus and you will get a 15/16 angus x 1/16 hereford calf. Might as well be a full blood angus after that point. Anyone please feel free to correct my math if I am wrong - it is early in the morn....

You got it

The way I've always done it is to divied the percentage of each parent in half and then just add the percentages by breed back togehter. Works for my math challanged brain

Doesn't matter how you do it if you get the correct answer(which you did and that's the way I figure it too )except 100% Angus + 98+% Angus =GREAT CATTLE.

Just have to keep it simple for my simple mind.
There used to be a computer program from one of the universitys that you could plug the percentages of the parents into and it would give you the percentages for the offspring. Took longer to get the data in then it does to just do the math on paper.

Thanks for the math lesson. I can figure it out now Dun's way. (Yet another simple mind!)

:lol: :lol: :lol: Doggone it dun, looks like someone just hit you between the eyes with a 2 by 4.

So how long would it take if the Angus bull was regestered to have registerable calves?

Never, the Angus association nor the hereford association allows breeding up.
