the other animal proteins that are now available.
However, European feed plants can already
use insect oils, which are authorized for poultry
and pigs, aquafeed, pet food and young animals.
In this case, they are added to whey up to 15-30% as
local replacement of copra oil.
"Insect fat is a natural part of monogastric diets
when meeting farmed animals' and pets' nutritional
requirements," says Walraven. It contains approximately 70% of saturated fatty acids (40% of C12, 8%
of C14, 12% of C16, 27% of C18) and 30% of unsaturated fatty acids (11% C18:1 and 14% C18:2).

Insect byproduct research
The feed industry isn't waiting for regulations to
change before there's an in-depth investigation into the
virtues of insect proteins and oils.
For example, Gilles Caby from Cargill France
notes research has shown that the fat is the main variable component of black soldier fly. The level depends
on the larvae feeding substrate, which can range from
7-43% in insects, and then may vary depending on the
extraction process.
Mealworm is less variable due to its stricter feeding

Black soldier flies and mealworms account
for 80% of the scientific research related to
insects as animal feed ingredients.

requirements, even if those data must be confirmed to
include variability between each production plant.
"We're quite sure that insect products may take
place of other raw material for aquafeed and we use
them already," Caby reports. "But we must be sure
about the quality in regard, mainly, to rancidity rate
and amine biogens contents that we need to be as low
as possible. And even if we've got data for formulation
matrix, we keep it secure with [the] incorporation of
no more than 0.5% oil and 5-10% protein meal for the
moment, waiting for more trials."

Antimicrobial properties of insect oil
Insect oils are not only lipids, but they also contain
lauric acid, which is known to be a natural antimicrobial and has attracted the interest of nutritionists.
Walraven explains that insect fat might be used to
improve health and organic properties up to 2% in sow
feed and between 1-4% in piglets feed, with possible
inclusion in fattening pigs feed. In poultry, she spoke
of 0.2-0.5% inclusion in the starter stage, 0.2-1% in
grower rations and up to 2% in the finishing phase.
"This high-quality source of fatty acid is highly
digestible thanks to medium-chain triglycerides. Its
saturated profile confers a low oxidation of the oil and
contributes to better quality preservation of the final
meat," Walraven says. "Insect oil is naturally highly
concentrated in lauric acid (>40%) known for its
antimicrobial properties, which have an effect on gut
microbiota and is active on gram-positive bacteria and
keeps gram-negative bacteria under control."
Mainly known as an alternative to copra oil due to its
fusion point, it has been tested on antibiotic-free farms.
"Zootechnical advantages have been demonstrated
through multiple trials," insists Walraven. "In swine,
we've partially replaced soy oil with an inclusion rate
of 0.5%, 1% and 2% in post-weaning diets and we've
obtained similar performances on growth. In another
