The objective of the present simulation was to use the National Chung Hsing University (NCHU) pig growth simulation
model to define the relationship between different protein and energy intake levels on the performance and body
composition of a growing pig. Fifty diets were used to describe the effects of protein and energy intake levels. The average
daily feed intake increases with both protein and energy intake levels. The average daily gain increases with increasing energy
intake and dietary ideal protein content. The feed conversion ratio, which is comprised of the feed used and the scaled feed
intake, decreases with increasing protein and energy intake levels. Increasing the diet protein content improves daily protein
retention and total protein mass. Increasing the diet energy content also improves daily lipid retention and total lipid mass.
The ratio of LR to PR decreases with increasing protein contents and decreasing energy contents.
