In this work the effect of partial or total replacement of fishmeal by plant protein sources and krill and squid meal on growth performance and shelf-life of gilthead sea bream was evaluated. Plant protein dietswith 50 g kg−1 of krill and 100 g kg−1 of squid were supplemented with synthetic amino acidsand at the end of the growing period weight showed no significant differences. The spoilage process of the fish was followed by physicochemical and microbiological measurements together with a colorimetric sensor array (CSA) specially designed for that purpose. The changes in the physicochemical parameters and microbial growth showed that shelf-life of samples were in all cases lower than ninedays. The CSA was not able to show significant differences between both diets, confirming the physicochemical and microbiological results. The fact that the type of feed had no effect on the freshness parameters studied demonstrates that total fishmeal replacement with plant protein blends in the proportions used in this work could be an excellent alternative for feed formulation in aquaculture.

Following a meal, a series of physiological changes occurs in fish as they digest, absorb and assimilate ingested nutrients. This study aims to assess post-prandial free amino acid (FAA) activity in gilthead sea bream consuming a partial marine protein (fishmeal) replacement. Sea bream were fed diets where 16 and 27% of the fishmeal protein was replaced by plant protein. The essential amino acid (EAA) composition of the white muscle, liver and gut of sea bream was strongly correlated with the EAA composition of the 16% protein replacement diet compared to the 27% protein replacement diet. The mean FAA concentration in the white muscle and liver changed at 4 to 8 h after a meal and was not different to pre-feeding (0 h) and at 24 h after feeding. It was confirmed in this study that 16% replacement of marine protein with plant protein meets the amino acid needs of sea bream. Overall, the present study contributes towards understanding post-prandial amino acid profiles during uptake, tissue assimilation and immediate metabolic processing of amino acids in sea bream consuming a partial marine protein replacement. This study suggests the need to further investigate the magnitude of the post-prandial tissue-specific amino acid activity in relation to species-specific abilities to regulate metabolism due to dietary nutrient utilization.

Conventional energy sources for poultry feed are scarce, expensive and highly competed for by man and industry in Nigeria which has resulted to subsequent high cost of feed and at times, poor quality of feed sold to farmers. Therefore, this study was carried out to evaluate the growth performance and feed cost benefit of broiler chickens fed various plant protein sources in acha grain based diet. A total of 120, one day-old Abor acre broiler chicks were procured and assigned in a Completely Randomized Design to four dietary treatments of three replicates and ten chicks per replicate. The four diets comprise soybean meal (full fat), soybean cake, groundnut cake and cashew nut meal at 28% inclusion level each in an acha based diet. Data on growth parameters (Daily feed intake, Final Weight Gain, Total Weight Gain, Feed-to-gain ratio and mortality) were collected daily and weekly. The results showed that the birds fed diet 3 having soyabean meal as the main plant protein source with 2700 Kcal/kg ME gave the best growth performance. It is also important to note that, the growth performance of birds fed diet 4 which had 28% cashew nut (full fat) had the poorest feed-togain ratio. The findings from this study further showed that using cashew nut (T4) as plant protein source in poultry (broiler chicken) ration is rather too expensive and production of cashew nut may have to increase so as to bring down the cost of production of broiler chicken. There was significant difference (P<0.05) in all the variables of feed cost benefit analysis. It is concluded that soyabean, whether used as meal/cake or full-fat confirmed its superiority over groundnut cake and cashew nut meal in this study. It is therefore recommended that farmers or poultry feed producers should use acha based diet with either soyabean meal or full-fat soyabean    Les sources d'énergie conventionnelles pour l'alimentation de la volaille sont rares, coûteuses et très concurrencées par l'homme et l'industrie au Nigéria, ce qui a résulté en un coût élevé des aliments et parfois, une mauvaise qualité des aliments vendus aux agriculteurs. Par conséquent, cette étude a été réalisée pour évaluer les performances de croissance et les avantages en termes de coûts d'alimentation des poulets de chair nourris  avec diverses sources de protéines végétales dans un régime à base de céréales acha. Un total de 120 poussins de chair Abor acre d'un jour ont été achetés et assignés dans une conception complètement aléatoire à quatre traitements diététiques de trois répétitions et dix poussins par répétition. Les quatre régimes comprennent la farine de soja (pleine matière grasse), le tourteau de soja, le tourteau d'arachide et la farine de noix de cajou à un taux d'inclusion de 28% chacun dans un régime alimentaire classique. Les données sur les paramètres de croissance (ingestion journalière, gain de poids final, gain de poids total, rapport alimentation / gain et mortalité) ont été collectées quotidiennement et hebdomadairement. Les résultats ont montré que les oiseaux nourris avec le régime 3 contenant de la farine de soja comme principale source de protéines végétales avec 2700 Kcal / kg ME ont donné les meilleures performances de croissance. Il est également important de noter que les performances de croissance des oiseaux nourris avec un régime alimentaire 4 contenant 28% de noix de cajou (gras) présentaient le rapport alimentation / gain le plus faible. Les résultats de cette étude ont en outre montré que l'utilisation de la noix de cajou (T4) comme source de protéines végétales dans la ration de volaille (poulet à griller) est plutôt trop coûteuse et que la production de noix de cajou peut devoir augmenter afin de réduire le coût de production du poulet à griller. . Il y avait une différence significative (P <0,05) dans toutes les variables de l'analyse coûts-avantages des aliments. Il est conclu que le soja, qu'il soit utilisé comme farine / tourteau ou gras entier, a confirmé sa supériorité sur le tourteau d'arachide et la farine de noix de cajou dans cette étude. Il est donc recommandé que les agriculteurs ou les producteurs d'aliments pour volaille utilisent un régime à base d'acha avec du tourteau de soja ou du soja entier.

Abstract The present study aimed to assess the appropriate level of replacement of fish meal (FM) with alternative plant sources in the feed fed to Oreochromis niloticus to evaluate the growth performance. Three isoproteinious (40% crude protein) diets were prepared from different ingredients viz., fish meal, corn gluten meal, wheat gluten meal, and bagasse kenna meal. O. niloticus showed a maximum increase in weight as 9.70, 11.09, 8.53 and 8.32 g during the 2nd, 2nd, 3rd and 2nd fortnight with feeding treatment A, B, C and D, respectively. The growth performance of the fish in terms of weight gain, specific growth rate, feed conversion ratio and protein efficiency ratio were found to be significantly (P < 0.05) higher in the fish fed with 20% replacement of fishmeal in diet B. The worst growth performance was observed in fish fed with commercial diet, designated as diet D. It was concluded that the fish meal can be replaced up to 20 percent with other plant protein sources without any negative impact on fish health. The replacement of fish meal with local plant sources (corn gluten meal, wheat gluten meal, soybean meal and bagasse kenna mix) will not only be beneficial to achieve better growth performance in O. niloticus, it will be a value addition as well.
