Low protein diets supplemented with essential amino acids (EAA) can improve growth performance, but dietary non-essential amino acids (NEAA) and nitrogen (N) content may be limiting factors. This limitation may ultimately affect the efficient utilization of EAA for optimal N retention and growth performance. As a benchmark, appropriate quantities of EAA and total N (TN) must be provided, using the EAA-N to TN ratio (E:T) to indicate that both are supplied in sufficient amounts. The present study generally observed a linear increase in N retention with increasing dietary Lys, and N retention was greater in the low E:T as compared with high E:T diets. A greater Lys requirement was observed in the low E:T compared with the high E:T-fed pigs. A low E:T ratio with Lys above current recommendations is warranted to maximize N retention.
