AS the world population grows, the need for increased
food production arises, especially protein.
Unfortunately, the process of increasing
animal protein leads to increase in methane production, a greenhouse gas
involved in global warming so the Food and Agricultural Organisation, FAO, in
seeking for alternative, noted that insect protein has the potential to curb
malnutrition problems.
To this end, the Sub-dean, Post-graduate School and
a lecturer in the Faculty of Agriculture, Nnamdi Azikiwe University, Awka, Dr.
Cordelia Ebenebe, came up with an alternative protein source. She speaks to
Vanguard Learning on her research works on the snail and earthworm as well.
The FAO requested that insect protein be investigated as an
alternative given the increase in human population and the fact that increasing
protein supply from ruminant animals will mean increase in methane production
as supply of protein from animals, especially ruminant animals, result in the
emission of methane into the atmosphere.
Methane is a very potent greenhouse gas involved in global
warming and its attendant negative effects. Insect protein has been found to be
one of the best animal proteins that could be used today.
•Dr. Cordelia Ebenebe…Chickens are tasteless these days
because of the lack of animal protein in the feed
“The research was born out of another research finding on
the methods of mass-producing the protein-rich whitish grub called African palm
weevil (Rhyncophorus phoenicis, Akpa ngwo in Igbo and Itun in
Yoruba) as an alternative protein source so instead of the normal protein in
milk for infants and toddlers, we are now incorporating the African palm
weevil.
This nutrient-rich infant formula will counteract
mortality in under-five children which is still a problem in Nigeria. The
product will undergo further analyses at NAFDAC. So far, we have been able to
test for chemical and sensory qualities.
“Before we made the product, we removed about 80 per cent of
the oil from the palm weevil because of the end-users – toddlers and babies –
as we are not too sure of the digestibility. The oil is good because it
contains only unsaturated/essential fatty acids that the body needs.
Those are the things we are testing before we come out with
the final product. “We incorporate the palm weevil into cereals and you
make it into a pap using hot water.”
Feedproduction:
“The same African Palm weevil because of the fat content,
can also be used in the production of fish feed. Unlike the conventional fish
feeds produced here which easily sink and pollute the water, this fish feed
does not sink.”
Earthworm:
“Another area of my research is in the use of earthworm
in livestock feed production because presently, the cost of fishmeal
which is the major animal protein source in livestock feed is very high
What they use mainly now is soybeans and soybeans does not
contain as much lysine and tryptophan, the major amino acids in
animal protein source and because earthworm is rich in these amino acids, we
have seen that it is a good alternative in the production of feed.
But the issue now is to be able to produce earthworm in
large quantities. We have reared them to a
large extent but we want to be able to produce in commercial
quantity needed in the industry for both fish and livestock feeds.
A farmer has promised that if we are able to produce a ton
of earthworms, he will buy all of them. The problem now is how to produce in
that large quantity but we believe that the same technology used in producing
small quantities can be used in producing large quantities, the only thing we
need is finance to expand the facility.”
Anti-aging agent from snail:
Weevils
“It has been discovered that the slime in snails, especially
the African Giant snail, has a lot of anti-aging substances.
Overseas, they do facial treatment using snails. The ladies
lie down and the snails crawl over their faces, leaving the slime which
contains anti-aging, anti-wrinkling substances.”
Not many people will want snails crawling all over their
faces hence the need to extract the active substances. Ebenebe said although
they have the technology but thery need funds to get the relevant machines.
“We have not been able to extract these substances because
we do not have the machines. We are looking for funds to get the machine. We
have the technology, we only need the machine now.
We are collaborating with the National Biotechnology
Development Agency, NABDA in this aspect,” she said.
