Notes:
True N conversion factor (Ft of thermally processed red kidney beans, rat feces and rooster excreta were determined based on Kjeldahl nitrogen and amino acid composition. Ft of processed beans ranged from 5.63 to 5.67, Ft of feces from rats fed the beans ranged 5.43 to 5.62, and Ft of excreta from roosters fed the beans ranged 3.06 to 4.18. The conventional N conversion factor (Fc of 6.25 overestimated the protein intake and output, and underestimated the protein quality of the beans. The difference of NPR (also AAS, EAAI, ALV, C-PER, PER, P-PER, and RNPR) values calculated by Fc and by Ft depends on the ratio Fc/Ft of the beans. The difference of TDP (also TDAA, BV and NPU) values calculated by Fc and by Ft is mainly dependent on the mtio Ft of diet/Ft of feces (excreta). Fc and Ft have a mixed effect on AASTDP and AASTDDA.
