The influence of dietary protein source (fishmeal, soy-protein concentrate and soy-protein concentrate supplemented with methionine) on voluntary feed intake, daily feeding rhythm and nutritive utilisation of diet was studied in the gilthead sea bream (Sparus aurata) fed by hand or demand feeding. Fish weighing 21 g were maintained indoors under natural conditions of temperature and photoperiod...

A study was conducted to evaluate genotype×feed interactions in a commercial strain of rainbow trout (Oncorhynchus mykiss). Microsatellite DNA markers were used to determine the pedigree of the top 1% and bottom 1% of progeny in a large scale commercial growth trial of 24,000 rainbow trout from 20 full-sib families (20 dams×10 sires in a nested mating design). The progeny were pooled at eyed st...

This study aimed at comparing two proteins sources on the performance of quail bred in Benin. Six groups of 45 quails from common breed, without sex discrimination, received diets containing either soybean meal (20 and 25%), fishmeal (20 and 25%), or their mixture (20 and 25%). The feeding period lasted six weeks. Quail weights were similar at the onset of experimentation but important variatio...

Sustainable aquaculture, from both ecological and economic perspectives, demands a substantial reduction of the amount of fishmeal used in aqua feed. Instead, plant-derived protein feed stuff, which provide a nutritious diet offer a promising alternative for inclusion in aqua feed. In this study, the effects of organic selenium supplementation in low and high soybean meal-based practical diets ...

The influence of fishmeal in the diet weaned piglets on indicators average daily gain was studied. It found that inclusion led to an increase and feed conversion starting period from 27 51 days.

Globally the need to substitute fishmeal with other animal protein sources in fish diet has gained more attention; which is occasioned by increasing cost of fish. A 12-week trial was conducted ascertain growth indices and biochemical response hybrid catfish (Clarias gariepinus(♀) Heterobranchus bidorsalis (♂)) fed cockroach meal supplement. total 800 were randomly distributed into four dietary ...

Maternal nutrition affects the development of fetus and postnatal performance calf. Methionine may play a critical role in developmental programming is likely deficient beef cows fed low-quality forage. The objective this study was to determine effect metabolizable methionine supply lactating during periconception period on cows, calves, subsequent offspring. This project involved two consecuti...

Following a brief historical review of the emergence of fisheries for forage fish that are primarily destined for reduction, and their competition with fisheries for human consumption, an account is given of landing trends in various parts of the world, and catch maps are provided for the 1970s and 2000s which allow spatial and temporal comparisons. A brief account is also given of the changing...

An 8-week feeding trial was conducted to investigate the effect of selenium-yeast (Se-yeast) supplementation on replacing fishmeal with soy protein concentrate (SPC) in diets for golden pompano (Trachinotus ovatus). The control diet (C) contained 400 g/kg fishmeal, which 40% and 80% C were substituted by SPC, or without 1 Se-yeast (four diets, R40, R80, R40 + Se, R80 formulated). weight gain fi...
