Estimation of total-tract starch digestibility using fecal starch concentration in fattening Japanese Black cattle.

ABSTRACT: Fattening Japanese Black cattle (Wagyu), renowned for producing marbled beef, derive essential energy from starch. While fecal starch concentration (FSC) can estimate total-tract starch digestibility (TTSD), equations developed for other beef production systems may not suit highly marbled beef production. This study developed a specific equation for estimating TTSD from FSC in Japanese Black cattle and compared it with data from other breed's production systems. Experiments with 49 Japanese Black cattle across four farms yielded 116 TTSD measurements. A database from 41 published studies on other cattle breeds (190 treatment groups, 2343 animals) was also analyzed. The Japanese Black cattle-specific equation (TTSD, % = 99.7 - 0.85 × FSC, %DM; R² = 0.89) showed a steeper slope co
