just unavailable. In fact, molasses can replace 100% lactose
with no problems, as long as it is done correctly (Figure 2).

once a sweet ingredient like molasses is used at sufficient
levels, other artificial sweetness might become redundant.
Considering the cost of modern flavors, this might not
be such a bad hypothesis to test. And, for those who argue
that modern flavors are more than taste, it can be reminded
that molasses-based diets are characterized by a distinct
"caramel" aroma that appears to appeal greatly to young
pigs. This mild expression of the Maillard reaction process in
early piglet feeds remains another aspect that awaits validation, although commercial evidence is supporting the notion.

More fines can be an advantage
That high-molasses diets result in more fines, due to more
fragile pellets, is an advantage and not a negative aspect.

Laxative effect
As for the laxative effect, it remains, and it
gets worse as molasses concentration increases. Gut leakage
(water entering the lumen due to osmosis) is not harmful, but
some prefer rock-hard fecal matter over high-feed intake and
excellent growth. Both cannot be achieved unless the feed
becomes prohibitively expensive. Nevertheless, the removal of
antibiotics has caused modern diets to be denuded of much of
their previous lactose levels and, as such, any replacement with
molasses will not bring about any significant alteration in fecal
matter consistency, unless feed intake increases.
Here, along with the change of fecal matter color, is a
