Genetics

Taking the Guess Work out of Selecting Bulls and Replacement Heifers

Since 2003, Igenity has worked with countless cattle breed associations, and seedstock and commercial cattlemen around the world to use the latest DNA technology to increase herd profitability.

The 8 Most Common Genetic Mistakes

1.  More Is Not Better

We can all do the math. +100 is more than +90 on yearling weight. On milk, +30 is more than +20 and that means more pounds to sell at weaning, right? However, these EPD’s only measure output – not profit. Profit is output minus cost. Unfortunately more output usually comes from more inputs – i.e. more feed. Animals with higher EPD’s for yearling and milk don’t convert better, they just eat more per day. Bigger EPD, higher feed consumption cattle have bigger mature weights. In fact, the dam of the average +100 YW EPD bull weighs over 1650 pounds in good body condition.

Magness Land and Cattle

The Beginning. The late Bob Magness, who founded Magness Land and Cattle, traded some of his commercial cows back in the 50’s for the stake he needed to begin TCI, which would ultimately become one of the largest cable television companies in the world.

Through the years and various business involvements, though, Bob always had some commercial cattle stashed around. And, he always reminded sons, Gary and Kim, that cattle were the bedrock of the family’s business success.

Fast forward, the Magness family was impressed enough with those first commercial heifers to purchase some Limousin bulls for their Colorado operations, as well as for the storied Silver Spur Ranch in Wyoming, which Magness owned for many years.
