Western Yeast Company’s 2X-2-2-5 has stood the test when it comes to improving palatability in cat food rations. The test took place at a private laboratory in October 2004. Western Yeast Culture 2X-2-2-5 was tested against a popular brand of brewers dried yeast in a 32% dry cat food. The cat food diets were identical except for the yeast source.

TWO DAY FELINE PALATABILITY TEST

Trial Procedure

One hundred fifty grams of each ration was offered to a panel of 20 cats. Bowl position was reversed daily to prevent ‘left-right’ bias. The brewers dried yeast was approached first on 19 out of 40 occasions but was only consumed first 10 of those times. Not only did the cats prefer the 2X yeast by a ratio of 1.21 to 1, but the total consumption was higher by 1.2 g/kg/day. See Chart A and Chart B below:
