5 factors regulating feed efficiency in pigs

In intensive pig production systems, feed comprises 60-70% of the total cost of pork production, and within feed, energy alone represents 50% or more of the total cost. Feed efficiency is key. Energy is a critical dietary component that is necessary for physical maintenance and growth. Feed efficiency signifies the efficiency with which the pig uses dietary nutrients for maintenance, lean gain and lipid accretion. In addition, feed efficiency strongly influences financial returns due to its
