diets are Hermetia illucens (black soldier fly), larvae of Musca
domestica (common housefly), and Tenebrio molitor (yellow
mealworm). Black soldiers larvae meal is a suitable ingredient in
g
rowing pigs diets, being valuable in particular for its protein,
lipid and Ca content and palatability (Newton et al., 1977). The
unbalanced aminoacid content of prepupae meal may be a limit-
ing factor in diets for early weaned piglets; additional refine-
ment, such as cuticle removal and rendering, may be necessary
to make it more suitable for piglets. The common housefly (M.
domestica) maggot is of particular interest because it can grow
on a large range of substrates and transform wastes into a valu-
able biomass rich in protein and fat. Sows and piglets fed maggot
meal did not show any adverse effect on performances and
health, and on sensorial property of meat (Bayandina and Inkina,
1980). Positive results were observed on weaned pigs fed a soy-
bean based diet supplemented with 10% maggot meal to replace
fishmeal (Viroje and Malin, 1989). Also yellow mealworm
(Tenebrio molitor) could be suitable in animal feeding due to its
high content of crude protein (47-60%) and fat (31-43%), but at
the moment no information is available for pigs and ruminants.
Future research on insect meal is needed, focused in particular
on safety hazards helping EU to assess conclusive laws on the
use of insect meals in pig diets.

Global fish production has grown steadily over the last 5 decades
reaching a total of 158 million tons in 2012 with more than 42%
coming from aquaculture. From 1980 to 2012, the global aquacul-
ture production grew at an average annual rate of 8.6% and this
increasing trend is expected to continue. In order to feed the
world population (9 billion in 2050), food production must
increase by 70% and aquaculture production will need to
increase by 133%. An increased availability of quality aqua feeds
is required for sustaining such rates of increase in aquaculture
production. Fish meal (FM) is the optimal protein ingredient in
fish feeds and still widely used. However, aqua feed production is
under increasing pressure due to limited supplies and increas-
ing price of FM. This means that FM will likely continue to be an
important ingredient, but it will increasingly be used in combi-
nation with other ingredients. Plants already deliver the majority
of the protein to diets for farmed fish due to the abundance,
p
otential for increased production and low cost. However, inclu-
sion of vegetable meal in aqua feeds (mainly soybean meal –
SBM) is limited since a number of adverse effects are observed.
Furthermore, the massive utilization in animal feeding of veg-
etable meal poses severe environmental issues. Therefore, sci-
entific research must focus on new protein sources able to save
biodiversity and to guarantee the sustainability of aquaculture
productions. FAO indicates insects as innovative source to be
employed in feed, due to their high nutritional value, especially
in terms of crude protein (CP) content. In aquaculture, trials
have shown that their use is possible with good growth perform-
ances even if some amino acid limitations have been highlight-
ed. Insect meal could thus make a significant contribution to the
sustainable development of the aquaculture industry. In this sce-
nario, the Committee on “Using innovative sources of protein
in animal feed”, appointed by the ASPA, is studying and dis-
cussing recent advances in feed research towards innovative
new high protein feedstuff to be included in feeds. Different top-
ics are focusing on insect meal, microalgae and animal by-prod-
ucts processed with innovative techniques that can be more sus-
tainable and available on a global basis.

There is increasing interest in incorporating nutrients that may
act as potential prebiotic sources in pig diets, including resistant
starch (RS). Pig colonic bacteria ferment RS to short-chain fatty
acids (SCFA) that exert several physiological effects related to
energy supply and renewal of intestinal cells. The aim of this
work was to evaluate whether the fermentation of RS from differ-
ent starches may influence SCFA fermentation patterns and
related kinetics. An in vitro experiment based on enzymatic
digestion followed by fermentation with faecal inoculum was
conducted and 5 native purified starches were tested. Each
ingredient was pre-treated with a pepsin-pancreatin hydrolysis
and 200 mg of each hydrolysed RS residue was then incubated in
