Hundreds and hundreds of years. It's still happening today, actually.

Why were the cattle ranches in Texas?

- The demand for beef from cattle rose in the East.


How long will it take for beef cattle to reach reproduction age?

Usually at the age of two, however, they will show heat cycles before then. Most farmers start breeding females timed to have the first calf at the age of two and most bulls depending on size can start to breed around 2.


How long for baby calf to reach 900 pounds?

Assuming you are referring to from birth to when the calf reaches 900 lbs, this depends on the breed of the calf. Continentals may take around 10 or 12 months to reach 900 lbs when they are put on good feed; British breeds may take around 18 months to reach this weight. The smaller cattle (Jerseys, Dexters, Low-line or Miniature cattle) that have a terminal weight at 900 lbs may take 3 or 4 years to reach this mature weight, if they do at all.


How long would it take for a cattle carcass to resurface if it drowned?

Humans will normally resurface approximately 2-3 days after drowning. This is because of the gas forming bacteria in their bowels. I would assume cattle would be about the same.


When roan color in cattle is the result of incomplete dominance between red and white color genes how would one produce a herd of pure-breeding roan-colored cattle?

Genetics is a tricky thing and there are no 100% guarantees that you will get the color you want. That being said the best possible way that this might be achieved would to test the genetics of each breeding pair. And continue to breed a successful pair, but have a care not to over breed them. A roan will not necessarily produce another roan either. Any born not of the color you want test to make sure of the genetics and decide to keep and breed or sell. It would take years of careful screening, breeding, trials and errors and disappointments. But with patience and persistence I believe that it would be possible. :)
