EVIDENCE OF GASTROINTESTINAL SENSING AND GUT-BRAIN COMMUNICATION IN RAINBOW TROUT (ONCORHYNCHUS MYKISS) IN RESPONSE TO THE AQUEOUS EXTRACT OF FISHMEAL AND ITS FREE AMINO ACID FRACTION

Using rainbow trout (Oncorhynchus mykiss) as a model, we aimed to obtain information about the gastrointestinal tract (GIT) amino acid sensing capacity and hormone production along regions of the GIT, in response to proline (Pro), to a solution of free amino acids (FAA) mimicking the composition of a fishmeal (FM)…

IMPACT OF DIETARY SUPPLEMENTATION OF SPICE EXTRACTS ON GROWTH PERFORMANCE, NUTRIENT DIGESTIBILITY AND ANTIOXIDANT RESPONSE IN BROILER CHICKENS

This study aimed to investigate the effects of supplementing broiler chicken diets with an encapsulated product based on capsicum and other spice (black pepper and ginger) extracts on growth performance, nutrient digestibility, digestive enzyme activity and antioxidant response. To this end, 480 1-day-old male chicks were randomly assigned to two…

CHARACTERIZATION OF TRUFFLE-FLAVOURED OILS COMPARED TO VOLATILE ORGANIC COMPOUNDS (VOCS) OF TUBER MELANOSPORUM TRUFFLES USING SENSORY AND CHROMATOGRAPHIC ANALYSIS BY HS-SPME/GC-MS

The secret of the great popularity of truffles lies mainly in their volatile organic compounds (VOCs), which produce their characteristic smell. This paper provides an overview of truffles in general as well as of their origin and their physicochemical, nutritional, organoleptic and biological properties. As an example of the volatile…

EFFECTS OF A PHYTOGENIC SUPPLEMENT CONTAINING OLIVE BY-PRODUCT AND GREEN TEA EXTRACTS ON GROWTH PERFORMANCE, LIPID METABOLISM, AND HEPATIC ANTIOXIDANT CAPACITY IN LARGEMOUTH BASS (MICROPTERUS SALMOIDES) FED A HIGH SOYBEAN MEAL DIET

A 10-week growth trial was conducted to investigate the effects of a phytogenic feed additive (PFA) containing olive by-products and green tea extracts supplemented to a reduced fishmeal/high soybean meal diet on the growth performance, hepatic antioxidant capacity, lipid metabolism, and liver health of largemouth bass (Micropterus salmoides). Three experimental…

TRIBUTYRIN SUPPLEMENTATION IN FISH AND CRUSTACEAN NUTRITION: A REVIEW

Short-chain fatty acids, including butyrate and its derived forms, have been used as dietary supplements to reverse or ameliorate the potential negative effects of plant-derived ingredients in aquaculture diets, and have a multitude of well-demonstrated physiological and health enhancing effects in mammals and livestock. Tributyrin, a butyric acid derivate, has…

THE USE OF AN OLIVE POMACE EXTRACT FROM OLEA EUROPAEA AS AN EFFECTIVE NATURAL SOLUTION TO THE REPLACEMENT OF ANTIBIOTICS IN BROILER CHICKEN DIETS

The current need to find alternatives to the use of antibiotics in poultry feeds is opening opportunities for natural extracts with functional properties. The present study aims to evaluate the effect on performance of 2 solutions based on natural extracts compared to a commercial mixture of antibiotics in broiler diets.…
