Abstract:
Use of existing and emerging management technologies enable beef producers to improve breeding performance of heifers during the first breeding season and during subsequent calving and rebreeding periods as 2 year olds. These practices ensure that heifers that enter the herd as raised or purchased replacements contribute to the general performance and productivity of an entire cowherd immediately, and cumulatively long-term. Rebuilding the US cowherd requires careful consideration and use of these newer management technologies. Veterinarians will play a crucial role in influencing the technologies used during the rebuilding process.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
