Fish meal free diets were formulated to contain graded protein levels as 25% (diet 1), 30% (diet 2), 35% (diet 3) and 40% (diet 4). The diets were fed to tambaqui juveniles (Colossoma macropomum) (46.4 ± 6.3g) in randomly designed recirculating systems for 60 days, to determine the optimum protein requirement for the fish. The final weight of the fish, weight gain (28.1, 28.5, 32.2, 28.0g) and specific growth rate increased (P>0.05) consistently with increasing dietary protein up to treatment with 35% protein diet and then showed a declining trend. Feed intake followed the same trend resulting in best feed efficiency (62.5%) in fish fed diet with 35% protein. Similarly, the protein intake increased significantly with increasing dietary protein levels and reduced after the fish fed with 35% protein; while protein efficiency ratio (2.28, 1.99, 1.87, 1.74) decreased with increasing dietary protein levels. Carcass ash and protein had linear relationship with dietary protein levels while the lipid showed a decreasing trend. Ammonia content (0.68, 0.73, 0.81, 1.21 mg L-1) of the experimental waters also increased (P<0.05) with increasing protein levels while pH, dissolved oxygen and temperature remained fairly constant without any clear pattern of inclination. Broken-line estimation of the weight gain indicated 30% protein as the optimum requirement for the fish.

AbstractTwo experiments were designed to test the possibility of partially replacing fish-meal protein in rainbow trout either with maize-gluten meal (MGM) (experiment 1) or potato protein concentrate (PPC) (experiment 2). Rainbow trout (Oncorhynchus mykiss) 30 g initial average weight were given diets containing different levels of MGM or PPC proteins ranging from 0 to 0·4 or to 0·6 of dietary protein, respectively. Substitutions of fish meal either by MGM or PPC were carried out establishing two different total dietary protein levels; 350 and 450 g/kg. Results showed that the MGM diets were acceptable and gave a significant enhancement (over 0·37 in the better case) in nutrient utilization when compared with those including only fish meal. On the contrary, diets including PPC were poorly accepted, and the growth offish and nutrient utilization were negatively correlated with dietary levels of PPC. It is concluded that levels of MGM representing around 400 g/kg diet can be used in foods for rainbow trout, whereas PPC appears not to be a suitable protein source for those fish.

Recent concerns over the seasonal availability and high cost of conventional protein sources has necessitated the search for alternative feed protein with lesser feed-food competitive properties yet desirable and appropriate to poults. A study was designed to determine the response of exotic turkey poults (Meleagris gallopavo) to diets substituted with varying levels of hydrolysed feather meal (HFM) or blood meal (BLM) as partial replacement for fishmeal for 112days. One hundred and ninety-two British United Turkeys BUT) were allotted to eight dietary treatments comprising four replicates and six birds per replicate. The birds were arranged in a 2 × 4 factorial arrangement of two protein sources (Hydrolysed feather meal or Blood meal) included at 4 levels (0, 10, 20 and 30%). Diets 1-4 were formulated such that fish meal in control was replaced by feather meal, protein for protein. Diets 5-8 wereformulated such that fish meal in control was replaced by blood meal, protein for protein and included at 0, 10, 20 and 30%. Treatments 1 and 5 were the control groups. Data obtained were subjected to Analysis of Variance using SAS. Turkeys fed test ingredients at 20% substitution level recorded higher (p<0.05) final weight and weight gain and best FCR at starter phase. Cost of feed/kg diet reduced (p<0.05) as the substitution level of test ingredientincreased. Nutrient digestibility and energy metabolisability increased with increased substitution levels of test ingredients at the starter phase. Starter turkeys fed hydrolysed feather meal recorded higher energy metabolisability. It can be concluded from this study that substituting turkey diets with Hydrolysed feather meal and Blood meal at 20% inclusion level improves performance, nutrient digestibility and energy metabolisability.

AbstractMany studies with fin fish have demonstrated the potential to use alternative dietary protein sources to fish meal based on growth responses, although these trials mostly neglect to determine if such protein sources affect immune function. This study investigated the effect of fish meal replacement with dehulled lupin meal (LPN) or hydrolysed poultry feather meal (FTH). Atlantic salmon (Salmo salar L.) parr were supplied isonitrogenous and isoenergetic diets with 40% of the dietary protein provided by LPN or FTH, or 400 g/kg of the dietary protein provided equally by LPN and FTH (MIX). A diet mainly containing fish-meal protein acted as a control (CON). Growth, immune function, blood chemistry and disease resistance were assessed after 56 days. Significant differences (P < 0·05) in weight gain were detected between Atlantic salmon given the CON and FTH diets, whilst those salmon given LPN and MIX did not differ from any other. Productive protein values were significantly lower (P < 0·01) for salmon on FTH compared with those on CON and MIX. Immune function (as assessed by lysozyme, antiprotease, neutrophil oxygen radical production and plasma total immunoglobulin) and blood chemistry (as assessed by plasma total protein and glucose) were not significantly (P > 0·05) affected by any diet. Mortality rates of Atlantic salmon challenged with Vibrio anguillarum were not influenced by diet. These data suggest Atlantic salmon could be supplied diets with the fish meal component reduced to supply approximately 600 g/kg of the total protein, with the remaining 400 g/kg supplied by dehulled lupin meal or a combined dehulled lupin and hydrolysed poultry feather meal without any adverse effects on growth, immune function or blood chemistry.
