Although the livestock sector has a significant contribution to the national economy, production per animal is extremely low. The average lactation milk production of the indigenous cows ranges from 494–850 kg under optimum management (EARO 1999; Haile et al. 2009a). The trend is similar to beef production. It is indicated that crosses of Ethiopian Boran with Hereford, Aberdeen or Charolais had 20–30% higher body weight than the pure Ethiopian Boran (EARO 1999).
