better. Piglets do not have a lactose
requirement per se; they rather require sugars that are simple enough
to digest, and for that, starch is not
the ideal energy source (albeit the
least expensive one). Lamentably,
cooked starch cannot replace the
need for simple sugars, even though
it is much better digested than raw
starch. The exact level of simple
sugars is often dictated by the upper
cost constraint for overall feed price,
and in turn, it defines feed intake
potential for such feed. It is widely
known that piglets respond linearly
to lactose concentration in their
feeds - at least in the first couple
weeks post-weaning. In contrast,
prolonging feeding high levels of
simple sugars will invariably lead to
osmotic diarrheas, as such ingredients are known laxatives.
Once, dried whey was the
only source of any immunoglobulin in piglet diets. Then animal
plasma was discovered, and it was
the ingredient that proved beyond
any diet the need to consider immunoglobulins in piglet feed design.
Animal plasma is still being used in
many countries, but less expensive
alternative sources of immunoglobulins have been produced in
the form of egg immunoglobulins.
There are positive and negatives, as
always with all ingredients, but cost
remains - in my opinion - the
defining challenge when it comes to
choose between animal plasma and

egg immunoglobulins. Research has
proven that piglets respond favorably
to much higher levels of immunoglobulins than those used today
commercially, but piglet feed buyers
tend to react very negatively when
they are faced with the ensuing price
of such highly effective feeds.
THE VACCINE FOR ALL SEASONS
From summer heat to winter frost, the ecology of a broiler
house is constantly changing, which can lead to an
increased coccidiosis challenge. The precocious strains of
HATCHPAK® COCCI III vaccine induce optimum immunity
with minimal lesions.1 So, at whatever level of coccidiosis
challenge, your flock can be safely protected year round.
