“…O CDa da energia bruta do FS para a truta, avaliado por Aksnes & Opstvedt (1998), foi de 56,00%, e para o TC avaliado por Gomes & Kaushik (1990), de 75,20%; estes resultados são inferiores aos obtidos no presente estudo, demonstrando que a tilápia do Nilo, por ser um peixe de hábito alimentar onívoro, apresenta melhor aproveitamento da energia de alimentos de origem vegetal quando comparada aos carnívoros.…”

“…O TG apresentou CDa da PB de 96,30%, valor este superior ao encontrado por Degani et al (1997b), para a farinha de trigo (91,26%) e superior ao encontrado para o triguilho por Hanley (1987) Hanley (1987) (83,26). O TC avaliado para a truta por Gomes & Kaushik (1990) apresentou CDa da PB inferior (84,80%). Com relação aos CDa da PB determinados, podemos verificar que geralmente a tilápia do Nilo, apresenta igual ou superior capacidade de aproveitamento dos alimentos avaliados, com relação aos resultados obtidos por diversos autores, com outras espécies, utilizados como base de comparação.…”

RESUMO -O experimento foi conduzido com o objetivo de avaliar os coeficientes de digestibilidade aparente (CDa) da matéria seca (MS), energia bruta (EB) e proteína bruta (PB) do farelo de soja (FS), milho (MO), trigo (TG), farelo de trigo (FT), milheto (MT), triticale (TC), farinha de varredura de mandioca (FM) e óleo de soja (OS) para tilápia do Nilo da linhagem tailandesa. Foram utilizados 100 animais revertidos sexualmente, com peso médio de 37,61 ± 4,98 g distribuídos em dois tanques de alimentação de 500L e coleta de fezes pelo sistema modificado de Guelph em dois aquários (150 L Apparent Digestibility of the Energy and Nutrients of Conventional and Alternatives Foods for Nile Tilapia (Oreochromis niloticus)ABSTRACT -The trial aimed to evaluate the apparent strain digestibility coefficients (CDa) of dry matter (MS), gross energy (EB) and crude protein (PB) of soybean meal (FS), corn (MO), wheat (TG), wheat meal (FT), millet pearl (MT), triticale (TC), cassava meal (FM) and soybean oil (OS) of Nile tilapia fingerlings of Thai. One hundred sexual reverted animals were used, with a mean weight of 37.61 ± 4.98g, distributed in two alimentation 500L mansory tanks and feces collect in modified Guelph system in two 150L aquariums. CDa was determined by an indirect method, with 0.1% chromic oxide (Cr 2 O 3 ) as marker. CDa of MS, PB and EB was 65.49, 89.58 and 71.38 for FS; 73.22, 93.40 and 76.63 for MO; 86.51, 96.30 and 87.07 for TG; 66.79, 91.00 and 68.81 for FT; 77.96, 94.91 and 89.12 for MT; 68.51, 94.78 and 80.55 for TC; 91.11, 97.52 and 91.40% for FM, respectively, and for EB of soybean oil 89.85%, the values of digestible protein (%) and energy (kcal/kg) were 42.19 and 3057.63 for FS; 7.18 and 3037.03 for MO; 11.01 and 3423.66 for TG; 13.44 and 2825.88 FT; 13.88 and 3755.55 MT; 13.74 and 3230.69 for TC; 1.76 and 3280.09; for FM and 8485.28 kcal/kg of energy digestible for OS. The results showed that the protein and energy of these foods are efficiently used by Nile tilapia. To formulate complete diets the digestible protein and energy values must be used.

“…Generally it has been observed that a partial substitution of fish meal by plant protein sources is well supported by fish, so currently more than 30% is already replaced in most commercial fish feeds (Teskeredzic at al., 1995;Forster et al, 1999;Burel et al, 2000;Vielma et al, 2000). Under conditions of partial replacement of fish meal, reasonably good growth performance has been observed with minor effects on metabolism (Gomes and Kaushik, 1990;Kaushik and Mambrini, 1994;Sanz et al, 1994;Carter and Hauler, 1995;Gomes et al, 1995;Robaina et al, 1995;Teskeredzic at al., 1995;Kissil et al, 2000;Refstie et al, 1997;Médale et al, 1998;Refstie et al, 2000). Fish meal free diets have also been used with success in some studies with rainbow trout (Kaushik et al, 1995;Watanabe et al, 1998).…”

“…Substitution of fish meal by alternate protein sources has been the object of study since more than three decades (Fowler, 1980;Dorsa et al, 1982;Tacon et al, 1985;Smith et al, 1988), possibly reducing production costs but definitely having a beneficial impact on environmental loads, locally with regard to phosphorus discharge (Watanabe and Pongmaneerat, 1993;Ballestrazzi et al, 1994;Hardy, 1995;Burel et al, 1998;Riche and Brown, 1999;Barrias and Oliva-Teles, 2000) and globally over the preservation of wild fishery resources. In spite of the lower protein content, the deficiency in some indispensable amino acids (IAA) and the presence of anti-nutritional factors (ANFs) frequently found in most plant protein sources (Kaushik, 1990;Francis et al, 2001), many studies have demonstrated the possibility to incorporate such ingredients in feeds for salmonids (Gomes et al, 1993(Gomes et al, , 1995Oliva-Teles et al, 1994;Hardy, 1996;Forster et al, 1999;Refstie et al, 2000;Burel et al, 2000;Vielma et al, 2000).

Two diets based on fish meal (FM) or on a mixture of plant protein sources supplemented with free amino acids (PP) were fed to rainbow trout having a mean initial body weight of 162.5 g reared at 17±1 °C for 24 weeks to evaluate the effect of plant protein sources on fish growth, morphological and body quality traits. At the end of the growth study, samples were withdrawn for chemical analyses as well as measurements of different parameters of quality. Compared to the FM group, the trout fed diet PP had lower growth rates (mean final body weight 663 vs. 800 g), feed efficiency (0.95 vs. 1.07) and protein efficiency ratio (1.96 vs. 2.13). Trout fed diet PP were also characterised by a lower dressed weight (89.45% vs. 91.07%), hepato-somatic index (0.92% vs. 1.01%) and fillet lipid content (5.50% vs. 6.98%), but had a higher mesenteric fat (5.65% vs. 4.08%), viscero-somatic index (10.55% vs. 8.93%) and fillet crude protein content (20.53% vs. 19.93%). The muscle fatty acid composition reflected that of the diet with a higher level of polyunsaturated (n-6) fatty acids in trout fed diet PP and a higher content in polyunsaturated n-3 fatty acids and n-3/n-6 ratio in trout fed diet FM. Sensory analysis was carried out at 5 days post-mortem on microwave-cooked dorsal portions of fillets stored at 1 °C with ice covering. The results of the triangular test showed differences between groups (P<0.01) in organoleptic characteristics as well as in visual colour. Descriptive tests pointed out that fillets of trout fed diet PP exhibited higher hardness, less sweetness and less odour intensity than trout fed diet FM.
