Feed Strategy - January 2020 - 33

To answer this problem, we must point fingers
to ourselves - the animal feed industry - because
we have been engaged in a price battle instead of
promoting quality and performance.
For those who want to utilize high-quality piglet
feeds that can boost piglet lifetime performance, the
following aspects should be considered and discussed
seriously with an attending nutritionist who has a
complete understanding of the farming operation.

Lactose and other
simple sugars
Piglets require lactose (or other
simple sugars equivalent to lactose)
to thrive post-weaning due to their immature digestive
systems. In healthy animals, the feed intake response
to lactose is linear up to 30% dietary lactose. In sick
and challenged animals, the response to lactose is
not clear and, in fact, too much lactose can lead to
secondary gut health implications.
Lactose can be replaced by dextrose, sucrose and
molasses. Nevertheless, lactose is a laxative per se
and as such it can induce osmotic diarrhea in piglets,
especially if feed intake is excessive. As such, scouring
piglets should not receive high-lactose diets, and highlactose diets should, in general, be preserved for piglets
right before and after weaning. Ideally, the four days
before and after weaning is where the first feed should
be directed for best results.

Fiber, now and then
Fiber is generally deemed undesirable in early piglet diets
because it reduces feed intake
and the digestibility of other nutrients. Most piglet
diets should contain less than 3% crude fiber. With
the advent of antibiotic-free feeds, some functional
fibers can act as prebiotics at the gastrointestinal
level, providing substrate for the proliferation
of beneficial bacteria. This establishes a healthy
microflora excluding most pathogenic bacteria.
Sources of functional fibers include beet pulp,
chicory pulp and carob meal. These are mainly

fermentable fibers acting at the hind gut level.
Insoluble fibers are also considered beneficial for
the upper digestive tract part as they can act as a
way of reducing water leakage and in general aid
digestibility, motility and overall gut health.

Energy and lipids
Piglets around weaning time are
not able to fully digest animal fats,
such as lard and tallow. They benefit
from vegetable oils and fats, such as soybean oil and
especially coconut fat. Piglet diets should be rich in
energy because at weaning animals are in a negative
energy state due to low feed intake. As such, weaning
diets should contain about 11 MJ NE/kg, dropping to
about 10 MJ NE/kg at the time of exiting the nursery
phase. An excellent source of lipids is full-fat soybeans
(extruded or otherwise thermally processed). Their
lipids are largely inside cells and as such they are not
prone to leaking. This enables "high-fat" piglet diets
to be formulated with relative ease. Functional lipids
(such as sources of omega-3 fatty acids) are considered
today as the new frontier in piglet nutrition as they can
enhance immune status in the absence of antibiotics.

Protein and amino acids
Piglet diets should contain as little
crude protein as possible, especially
when diets do not control enough gut
microbial controlling agents (such as antibiotics). This
is achieved with the use of feed-grade amino acids and
the selection of appropriate highly digestible ingredients. High-protein diets reduce the available energy for
growth and provide substrate for the proliferation of
pathogenic bacteria.
A diet fed immediately post-weaning should
contain no more than 20% crude protein, falling to
18% at the end of the nursery period when pigs weigh
about 25 kg body weight. It should be noted here that
amino acids should be formulated based on an ideal
protein profile to enable rapid growth and improved
efficiency of feed utilization. In the case of protein
sources, we must differentiate between plant-based
