Breed Ratio Understanding

Howdy, I am just starting out my cattle company and have been looking at the different breeds. Currently I just have a commercial herd. But, I'm interested in becomming a purebred breeder. I'm most interested in the Brangus breed and have been doing some research. Can anyone help me to understand what the 3/8 Brahman and 5/8 Angus means. I'm not quite sure how they derive the ratio. Thanks!

If you cross Angus with Brangus, you get a 1/2 Angus, 1/2 Brahman animal. If you take that animal and breed it to a 3/4 Angus, 1/4 Brahman, you get what is considered a purebred Brangus - 5/8 Angus, 3/8 Brahman. You might also consider using Simbrah. That is 5/8 Simmental 3/8 Brahman. (math: 4/8 (1/2) + 6/8 (3/4) = 10/8 divided in half = 5/8%) Jeanne

Your post was bang on until you did the math. No animal has more than 8/8ths. You had the right idea but the equation is wrong.

To get your 5/8 angus, 3/8 brahman you breed a half blood (4/8 angus 4/8 brahman) to a 3/4 angus(6/8 angus 2/8 brahman). Take half of each ratio of angus blood (1/2 of 4/8 is 2/8 and 1/2 of 6/8 is 3/8) and add them together. 2/8 + 3/8 = 5/8. This is the ratio of the total. In a percent form it is 62.5%

To check the math, do the brahman blood, (1/2 of 4/8 is 2/8, and 1/2 of 2/8 is 1/8) 2/8+1/8=3/8..... 3/8 brahman + 5/8 angus = 8/8 or one whole animal called brangus.
