Ruminal pH in cattle (Bos primigenius f. taurus) and moose (Alces alces) under different feeding conditions: a pilot investigation
Feeding recommendations for captive wild ruminants strictly restrict the use of high-starch/low fiber concentrates and fruits and vegetables, because of their potential to induce acidotic conditions in the forestomach. Nevertheless, such items are still used, and actual measurements documenting the...

Feeding recommendations for captive wild ruminants strictly restrict the use of high-starch/low fiber concentrates and fruits and vegetables, because of their potential to induce acidotic conditions in the forestomach. Nevertheless, such items are still used, and actual measurements documenting the consequences are rare. We used a captive moose (Alces alces) and two domestic cows (Bos primigenius f. taurus), equipped with intraruminal pH sensors, to monitor the short-term effects of five diets (a ‘natural diet’ of browse for moose and grass hay for the cows; a grass diet; an alfalfa hay diet; and a diet where concentrates, apples and carrots were offered, along an ad libitum roughage source, at two increasing levels – ration 1 and 2, respectively).
