SPECIFIC BLOOD PLASMA CIRCULATING MIRS ARE ASSOCIATED WITH THE PHYSIOLOGICAL IMPACT OF TOTAL FISH MEAL REPLACEMENT WITH SOYBEAN MEAL IN DIETS FOR RAINBOW TROUT (ONCORHYNCHUS MYKISS)

High dietary SBM content is known to induce important physiological alterations, hampering its use as a major FM alternative. Rainbow trout (Oncorhynchus mykiss) juveniles were fed two experimental diets during 9 weeks: (i) a FM diet containing 12% FM; and (ii) a vegetable meal (VM) diet totally devoid of FM…

REPLICA BETTER THAN NATURAL PRODUCT

Essential oils are often used to improve palatability of swine feed. As a natural product, their composition varies, leading to inconsistent results under experimental conditions. Reconstituted versions that mimic the properties and allow standardized blends could clearly demonstrate their effects.

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)…

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…

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…
