The results of the pilot experiments compared with the traditional
feeding diets detailed in Table 2.15 show that:

• Permeate alone shows better feeding than when being supplemented
with nitrogen.
• Permeate fed results in terms of weight gain in 64 days is 33.9%,
which is almost the same as molasses (34.6%) and better than water
(28.2%).
• Permeate has the highest yield efficiency of 7.5, which is kilogram
whey fed per kilogram live weight gain, compared to molasses at 9.2.

Thus we could conclude that whey is technically acceptable, and safe as a
food source for animals.
The pilot experiment is also important to determine problems that could
be avoided in the prototype, for example developing a provisional business plan
