COPROPHAGY PREVENTION AND AVAILABILITY OF AMINO ACIDS IN WHEAT FOR THE GROWING RAT

Abstract
The prevention of coprophagy had no significant effect on the availability of amino acids in a pure wheat diet consumed by male rats weighing 80 and 300 g, except in one instance. In the lighter, younger rats, a significant difference occurred in the amount of lysine available: 89% for rats with sham tail cups, 94% for control and 96% for those with real tail cups. Prevention of coprophagy in rats consuming a supplemented wheat diet or pure wheat had no significant effect on the weight gain over a period of 35 days, or on nitrogen balances at the two different stages of growth.
