Improvement of feed intake through supplementation with an attractant mix in European seabass fed plant-protein rich diets
Provedor de dados: 5
Autores: Dias, Jorge; Gomes, Ef; Kaushi, Sj.
The incorporation of an attractant mixture by substitution of an equivalent amount of basal dietary mixture was studied in terms of feed intake and growth performance in European seabass juveniles (mean initial weight : 17 g) fed plant-protein rich diets during 21 days. Three diets had as main protein sources; fish meal, or one of two soy protein concentrates (S and E). To the basal mixture of these last two diets, as well as to a corn-gluten based diet, an attractant amino acid mixture was added at a 2.5% level. Daily feed intake was measured throughout the experimental period. Feed intake and weight gain were highest in seabass fed the fish meal based diet. In those fed the soy protein concentrate diets, the addition of the attractant mixture improved...

Protein sources in feed for farmed fish
Provedor de dados: 5
Autores: Medale, Francoise; Kaushik, Sadasivam.
Fish require diets containing 30 to 55% of crude protein and an amino acid supply precisely adapted to meeting the needs for optimal growth. Fish meal is an ideal protein source for aquafeed because it has a high protein level (65% to 72%) with an ideal proportion of all ten indispensable amino acids that meet the requirements of all fish species. However, finding alternatives to fish meal has become an absolute necessity in order to reduce the reliance of aquaculture on marine ingredients. Animal by-product meals (meat meal, bone meal, blood meal, poultry by-product meal, hydrolysed feather meal) are used as alternative protein sources in aquafeed in extra-European countries. Since the use of animal protein in aquafeed is forbidden in Europe (except non...

Substitution of fish meal with plant protein sources and energy budget for white shrimp Litopenaeus vannamei (Boone, 1931)
Provedor de dados: 5
Autores: Suarez, J. A.; Gaxiola, G.; Mendoza, R.; Cadavid, S.; Garcia, G.; Alanis, G.; Suarez, A.; Faillace, J.; Cuzon, Gerard.
Fish meal (FM) has long been considered an essential ingredient for the formulation of shrimp feeds. Until recently, 12%FM was considered a minimum amount, below which weight gain would become reduced due to a reduction in feed intake. In order to test this perceived minimum value, an experiment was conducted on a long-term basis with 4 replicates. Four practical isonitrogenous and isoenergetic diets were formulated for Litopenaeus vannamei juveniles. Survival, weight gain, feed conversion ratio (FCR) and protein efficiency ratio were determined for 0, 6, 10 and 15% FM diets and a reference diet. Shrimp survival ranged from 84 to 86.5%. Shrimp fed a diet with 0% FM showed lower average weight and SGR compared to the other treatments (P&lt;0.05). FCR of...

Regulation of the somatotropic axis by dietary factors in rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 5
Autores: Gomez Requeni, P; Calduch Giner, J; De Celis, S; Medale, Francoise; Kaushik, Sadasivam; Perez Sanchez, J.
The activity of the somatotropic axis was analysed in juvenile rainbow trout (Oncorhynchus mykiss) fed either a fishmeal-based diet (FM) or graded levels of plant proteins to replace 50 % (PP50 diet), 75 % (PP75 diet) or 100 % (PP100 diet) of the fishmeal protein. For this purpose, partial cloning and sequencing of the gene encoding rainbow trout growth hormone receptor (GHR) was first accomplished by RT-PCR, using degenerate primers based on the sequences of non-salmonid fish GHR. Growth rates and energy retention were lowered by the PP75 and PP100 diets and a concurrent and progressive increase in plasma levels of growth hormone (GH) was found. However, no changes in hepatic GH binding and total plasma insulin-like growth factor (IGF)-I levels were...

The time course of fish oil wash-out follows a simple dilution model in gilthead sea bream (Sparus aurata L.) fed graded levels of vegetable oils
Provedor de dados: 5
Autores: Benedito-palos, Laura; Navarro, Juan C.; Bermejo-nogales, Azucena; Saera-vila, Alfonso; Kaushik, Sadasivam; Perez-sanchez, Jaume.
The aim of the study was to determine whether changes in the tissue fatty acid (FA) profile follows a simple test dilution model after changing the dietary oil sources in gilthead sea bream. A 14-month trial was conducted with juvenile fish of 18 g initial body weight fed either a fish oil-based diet (FO diet) or vegetable oils replacing 33% (33VO) and 66% (66VO) of fish oil. The trial included 3 months feeding a fish oil finishing diet to follow the restoration of the FA profile with the FO diet. Fish oil replacement with/without a finishing phase of fish oil re-feeding did not affect growth and all groups reached 520-531 g body weight. Changes in body composition with weight gain did not modify the FA profile of fish continuously fed FO, 33VO or 66VO...

Combined replacement of fish meal and oil in practical diets for fast growing juveniles of gilthead sea bream (Sparus aurata L.): Networking of systemic and local components of GH/IGF axis
Provedor de dados: 5
Autores: Benedito Palos, L; Saera Vila, A; Calduch Giner, J; Kaushik, Sadasivam; Perez Sanchez, J.
Growth performance and growth regulatory pathways were examined in juvenile gilthead sea bream fed diets containing largely plant-based ingredients. Four isonitrogenous and isolipidic extruded diets with a low level (20%) of fish meal inclusion were formulated with graded levels of a vegetable oil mixture (17:58:25 of rapeseed: linseed: palm oils) replacing fish oil at 33, 66 and 100% (33VO, 66VO and VO diets). All diets were supplemented with lysine (0.55%) and contained soy lecithin (1%). Daily growth coefficients and feed efficiency over the course of an 11-week trial were almost identical in fish fed the FO, 33VO and 66VO diets. The VO diet reduced feed intake and growth without significant effects in proximate whole body composition, nitrogen or...

Effect of fish meal replacement by plant protein sources on non-specific defence mechanisms and oxidative stress in gilthead sea bream (Sparus aurata)
Provedor de dados: 5
Autores: Sitja Bobadilla, A; Pena Llopis, S; Gomez Requeni, P; Medale, Francoise; Kaushik, Sadasivam; Perez Sanchez, J.
Partial or total replacement of fish meal by a mixture of plant protein (PP) sources (corn gluten, wheat gluten, extruded peas, rapeseed meal and sweet white lupin) balanced with indispensable amino acids was examined in juvenile gilthead sea bream over the course of a 6-month growth trial. A diet with fish meal (FM) as the sole protein source was compared to diets with 50%, 75% and 100% of replacement (PP50, PP75, and PP100). The possible influence of diets on growth performance, plasma metabolites, gut integrity, liver structure, anti-oxidant and immune status was evaluated. Final body weight was progressively decreased with PP inclusion, but in PP50 and PP75-fed fish, feed efficiency (FE) was significantly improved and specific growth rates remained...
