Summary

The Illinois ideal amino acid pattern (IIP) supports optimal growth and nitrogen utilization in young pigs, outperforming other indispensable amino acid profiles. This research refines amino acid requirements for 10-kg pigs, enhancing feed efficiency.

Background:

Establishing precise indispensable amino acid (AA) patterns is crucial for optimizing piglet growth and nutrient utilization.
Previous amino acid profiles, including the Illinois final amino acid pattern (IFP) and the 1988 National Research Council (NRC) pattern (NRCP), may not be optimal for young pigs.
Chemically defined diets are valuable tools for precisely evaluating amino acid requirements.

Purpose of the Study:

To determine the ideal indispensable amino acid pattern for 10-kg crossbred pigs.
To compare the efficacy of four different indispensable amino acid patterns: IFP, Illinois ideal amino acid pattern (IIP), Wang and Fuller ideal amino acid pattern (WFIP), and NRCP.
To evaluate the impact of these patterns on pig growth performance and nitrogen utilization.

Main Methods:

Conducted two growth assays and one nitrogen balance experiment using chemically defined amino acid diets.
Fed four distinct indispensable amino acid patterns (IFP, IIP, WFIP, NRCP) with a standardized dispensable amino acid mixture.
Adjusted dietary amino acid levels across experiments to assess performance under varying nutrient densities and evaluated nitrogen utilization efficiency.

Main Results:

In high-level diets, all amino acid patterns supported similar growth performance.
Under reduced amino acid levels, pigs fed the IIP exhibited superior daily gains compared to IFP and NRCP.
Nitrogen utilization was significantly higher for IFP, IIP, and WFIP compared to NRCP, with IIP showing the greatest nitrogen retention.

Conclusions:

The Illinois ideal amino acid pattern (IIP) is superior to IFP and NRCP for promoting growth and nitrogen utilization in 10-kg pigs.
The Wang and Fuller ideal amino acid pattern (WFIP) contains excesses of several indispensable amino acids for young pigs.
The 1988 NRC pattern (NRCP) is likely first-limiting in leucine and other amino acids, leading to reduced nitrogen utilization.
