Total threonine intake for cats over the 6-month feeding period vs change in LBM

Cats grouped according to total threonine intake*LBM at baseline, g†LBM at end of 6 months, g‡Change in LBM, g§Total threonine intake, g¶
Low3661±1753369±177−292±4673.1±18.9

  • *Cats that completed the study (6 months) according to protocol whose threonine intake was less than the AAFCO minimum recommendation (low) or above the AAFCO minimum recommendation (adequate). The estimated threonine intake needed to maintain LBM for cats was calculated using the NRC estimate for energy intake and the AAFCO minimum recommendation for threonine intake. The estimated minimum threonine intake was 97.4 g for cats consuming control food and 102 g for cats consuming test food.

  • ‡LBM at end of 6-month feeding period, mean±SEM.

  • §Change in LBM from baseline to end of 6-month feeding period, mean±SEM. Low vs adequate groups are different at P<0.001.

  • ¶Measured food intake over the 6-month feeding period was multiplied by threonine concentration in food to calculate threonine intake over the 6-month feeding period for each cat, mean±SEM. Low vs adequate groups are different at P<0.001.
