Recent studies have demonstrated the impact of diet on microbiota composition, but the essential need for the optimization of production rates and costs forces farms and aquaculture production to carry out continuous dietary tests. In order to understand the effect of total fishmeal replacement by vegetable-based feed in the sea bream (Sparus aurata), the microbial composition of the stomach, f...

In experiment 1, 24 midlactation, multiparous Holstein cows were used in six 4 x 4 Latin squares to evaluate extruded-expelled cottonseed (EEC) as a source of ruminally undegradable protein (RUP). Diets were formulated to contain: 16% crude protein (CP), 35% RUP (SBM16); 18% CP, 35% RUP (SBM18); 16% CP, 40% RUP using EEC (EC16); and 16% CP, 40% RUP using a fishmeal-blood meal blend (FBM16). Mil...

For improving aquafeed sustainability, insect meal is currently considered the most promising alternative to fishmeal. However, in this regard, more data are still necessary avoid possible negative impacts on fish growth performance, metabolism, and welfare. The present study investigated effects of increasing inclusion Hermetia illucens (0%, 17%, 33% 50% feed, equating 0%, 34%, 66% 100% fishme...

Abstract The present study investigated the potential use of defatted black soldier fly ( Hermetia illucens ) meal as a protein source in formulated feed for juvenile lobsters, Panulirus ornatus . A total 160 heads lobsters with initial weight 0.24 ± 0.01 g and length 21.77 0.32 mm were distributed evenly into 16 rectangular fiberglass aquaria kept individually 8 weeks feeding experiment. Four ...

The replacement of fishmeal with plant protein sources has been studied in Penaeus vannamei. However, it only from the point view replacement, forgetting integral role that plays nutrition shrimp. This study aimed to determine if a supplement dietary phosphorus can sustain by blend feedstuffs, betaine and tauren as attractants still supporting homeostasis, growth, digestive enzymes, lipid-solub...

A research for eight weekswas conducted to evaluate the effect of substituting fish meal with local agricultural products in diet Nile Tilapia (Oreochromis niloticus).Three treatment dietaries were prepared. The dietary composition tested diets is as follows: A1/plant based-diet (Groundnut cake, sesame millet bran, maize and 0% meal) A2/fishmeal partial replacement meal, 10% A3/fishmeal 25% mea...

BACKGROUND Prenatally stressed offspring exhibit increased susceptibility to inflammatory disorders due to in utero programming. Research into the effects of n-3 PUFAs shows promising results for the treatment and prevention of these disorders. The purpose of this study was to investigate whether maternal fishmeal supplementation during pregnancy and lactation protects against programming of th...

A feeding trial was performed to investigate inclusion levels of distillers dried grains with solubles (DDGS) as a fishmeal replacement for juvenile Nile tilapia (Oreochromis niloticus). On a dry matter basis, five isocaloric [19.3 ± 0.4 kJ/g (mean ± SE)], isonitrogenous (39.1 ± 0.5% crude protein) diets were formulated to contain 17.5%, 20%, 22.5%, 25%, and 27.5% DDGS and compared against a 0%...

Two four-week feeding trials were conducted with fingerlings of Eurasian perch (Perca fluviatilis, 3.52 ± 0.08 g) and rainbow trout (Oncorhynchus mykiss, 1.49 0.05 fed graded levels dried (DWD) fermented (DWF) duckweed meal (Spirodela polyrhiza). The purpose these two was to evaluate DWD DWF as replacements for fishmeal. Fishmeal protein substituted by 12%, 24%, 35% compared control diets conta...

A revised method to determine solubility of nitrogen in dilute pepsin, using 0.0002% pepsin in place of 0.2% in AOAC Official Method 971.09, was tested in 16 laboratories with 12 samples of fishmeal. Results were calculated according to 2 procedures: AOAC Official Method 971.09 and a method described in 1964 by researchers at the Torry Research Station (Aberdeen, Scotland), and generally referr...
