a combination of coconut oil and lard to
mimic milk fat. Medium and long-chain fatty
acids both play important roles in creating a
highly nutritious and digestible product for
calves. Another important characteristic
of a high-quality dry fat is mixability. The
problem with creating a dry fat is that fat/
oil don’t mix with water and are therefore
not stable in solution. The solution – PEF is
a fat-droplet wearing a “jacket” of protein,
and makes a stable solution.
A sophisticated system of emulsification
and homogenization is required to make
PEF. This creates an encapsulated fat and
oil core, with a protein and lactose shell.
The quality of fat and oil matters as well –
not all milk replacers utilize human-grade
sources in the manufacturing of PEF,
which creates a highly palatable powder
that remains stable over time in the milk
replacer.
Caring For Calves
The Skinny on Fat
Jackson Matschke,
Western Canada Sales Manager,
Grober Nutrition
In early life, calves receive the majority of
their energy from lactose (milk sugar) and
highly digestible fat. This is because protein
is the least easily metabolized source of
energy for very young calves.
If providing milk replacer, it should be made
with a high-quality fat blend, which is crucial
for calves to maximize the highly efficient
growth period of the milk-fed stage.
After protein sources, fat takes up most
of the balance of a milk replacer formula.
For many products, it takes the form of
powdered fat, known as fat filled powder.
Most fat filled powders manufactured in
North America are based on animal fat,
which are low in medium chain fatty acids.
However, young calves require medium
chain fatty acids sourced from plants to
be able to digest and utilize fat efficiently.
Providing an appropriate blend of plant and
animal fat increases the overall digestibility
of both the plant and animal fats (versus
utilizing one source exclusively).
How do fat sources differ?
The ideal fat sources for quality milk replacer
have a few key characteristics. They must
provide the appropriate fatty acid profile,
have consistent globules to aid digestion
and mixing with water. The gold standard
for fat-filled powder is Protein Encapsulated
Fat (PEF). PEF contains easily digestible
medium and long-chain fatty acids by using
Fatty acid profile of PEF:
Medium chain fatty acids (coconut oil)
• Sensitive to salivary and gastric enzymes
that are intact from birth.
•  Protective effect against gram+ bacteria
(i.e. Clostridium perfringens).
Long chain fatty acids (lard)
•  Major energy source and provides Omega
3 and Omega 6 essential fatty acids.
•  Play an important role in anti-inflammatory
responses.
Protein Encapsulated Fat results
in an end milk replacer product
that is easily mixed by you, and
easily digested by the calf. Choose
a milk replacer with digestibility in
mind to ensure calves receive all
the nutrients they need to grow
and thrive.
