Resumo(s)
Macroalgae have been increasingly exploited worldwide for feed, food and biofuel
applications, due to their nutritive and bioactive compounds. Green seaweeds belonging to the genus
Ulva have high growth rates, which makes them suitable for being cultured in sustainable algae
production, such as an integrated multi-trophic aquaculture system. This is expected to increase the
use of Ulva sp. as an alternative source to conventional feedstuffs (e.g., cereals and soybean meal)
for poultry. The objective of the current study was to assess if the incorporation of 15% Ulva lactuca
in broiler chickens’ diet, combined or not with carbohydrate-active enzymes, would enhance meat
nutritional quality without compromising animal growth performance. Overall, U. lactuca led to
an accumulation of antioxidant carotenoids, n-3 PUFA and macrominerals, including magnesium,
potassium and phosphorus, in the breast muscle, with likely health benefits, without significantly
impairing growth performance. The supplementation of macroalgae with a recombinant ulvan lyase
reduced ileal viscosity with possible beneficial effects on broiler digestibility. Although dietary U.
lactuca showed potential to increase meat quality, it reduced meat overall acceptability, which suggests
the use of a lower algae inclusion level to prevent a negative meat sensory perception for consumers
