“…Measuring the activity of digestive enzymes is not enough to determine the value of a specific fish feed, as enzymes act in combination with feed composition, thus when associated with metabolic parameters they are a more reliable indicator of the fish nutritional status (Lundstedt et al, 2004). Usually, fish use less carbohydrate, demanding higher protein levels in the feeds (Kikuchi, 1999). However, several researchers showed the presence of carbohydrases, such as amylase, in many fish species (Ugwumba, 1993;Hidalgo et al, 1999;Alarcón et al, 2001;Lundstedt et al, 2004).…”

Digestive enzymes activity influence feed utilization by fish, and its understanding is important to optimize diet formulation. This study reports the digestive enzyme activities of jundiá juveniles fed diets with protein sources. Fish were fed six experimental diets for 90 days: MBY (meat and bone meal + sugar cane yeast), SY (soybean meal + sugar cane yeast), S (soybean meal), MBS (meat and bone meal + soybean meal), FY (fish meal + sugar cane yeast) and FS (fish meal + soybean meal), and then sampled every 30 days and assayed in two intestine sections for digestive enzymes -trypsin, chymotrypsin and amylase -activities; gastric protease was assayed in the stomach. Digestive and hepatosomatic index, intestinal quotient, digestive tract length and weight gain were also measured. Trypsin and chymotrypsin activities were higher (p < 0.0001) in fish fed diets containing animal protein sources (MBY, MBS, FY and FS diets). Alkaline proteases were negatively affected by dietary soybean meal in the SY and S diets. Amylase activity had greater variation between diets and intestine sections. Fish fed MBY and MBS diets showed higher gastric protease activity (p < 0.0001). Weight gains were higher in fish fed the MBS and FS diets (p < 0.05). Highest values (p < 0.05) of digestive tract length were observed in fish fed MBS and FY diets, but no correlation with enzymes activities was found. Hepatosomatic index (HSI) was affected by diet composition. Dietary composition influenced digestive enzymes activities of jundiá.

Este trabalho descreve a atividade de enzimas digestivas em juvenis de jundiá alimentados com fontes protéicas. Os peixes foram alimentados com seis dietas (90 dias): MBY (farinha de carne e ossos + levedura de cana), SY (farelo de soja + levedura de cana), S (farelo de soja), MBS (farinha de carne e ossos + farelo de soja), FY (farinha de peixe + levedura de cana) e FS (farinha de peixe + farelo de soja). A cada 30 dias, foram analisadas as enzimas digestivas (tripsina, quimiotripsina e amilase) no intestino. No estômago, foi mensurada a protease ácida. Foram estimados os índices digestivo e hepato-somático, quociente intestinal, comprimento do trato digestório e ganho em peso.

“…Os alimentos protéicos são responsáveis pela maior fração dos custos da ração na piscicultura intensiva e semi-intensiva (Boscolo et al, 2001), pois, além de comporem grande quantidade nas formulações (Kikuchi, 1999), apresentam maior custo que os alimentos energéticos. Alimentos protéicos alternativos à farinha de peixe têm sido estudados com o objetivo de diminuir o custo das rações aquícolas (Oliveira et al, 1997;Refstie et al, 1999;Booth et al, 2001;Siddhuraju & Becker, 2001); entretanto, um dos problemas encontrados para o uso destes materiais é a falta de informação dos valores de digestibilidade de seus nutrientes (Mukhopadhyay & Ray, 1997).…”

RESUMO -Foi conduzido um ensaio de digestibilidade para determinar os coeficientes de digestibilidade aparente (CD) da matéria seca (MS), energia bruta (EB) e proteína bruta (PB) da farinha de peixe (FP), farinha de vísceras de aves (FV), glúten de milho (GM) e levedura de álcool spray dried (LS) pela tilápia do Nilo, da linhagem tailandesa. Foram utilizados 100 peixes revertidos sexualmente, (peso médio de 37,6 ± 5,0 g) acondicionados em dois tanques de alimentação de 500 L e duas cubas cilíndricas com fundo cônico, de 150 L, para coleta de fezes. A determinação dos CD foi feita por intermédio da metodologia indireta, tendo sido utilizado 0,1% de óxido crômico (Cr 2 O 3 ), como indicador. As médias de temperatura, oxigênio dissolvido, pH e condutividade elétrica durante o período experimental foram de 25,8 ± 1,0 o C; 3,2 ± 1,4 mg/L; 6,8 ± 0,1; e 205,7 ± 16,6 µS/cm, respectivamente. Os CD da PB, EB e MS foram respectivamente de 90,66; 89,53 e 87,63 para FP; 82,03; 72,09 e 62,21 para FV; 97,61; 93,52 e 91,01 para GM; 77,39; 62,77 e 58,68 para LS. Os valores de proteína (%) e energia (kcal/kg) digestíveis, na matéria natural, de 53,01 e 3568,0 para FP; 47,65 e 3650,9 para FV; 65,34 e 5036,7 para GM e 32,19 e 2706,9 para LS. Palavras-chave: digestibilidade, nutrição, proteína, tilápia, Oreochromis niloticus Apparent Digestibility of Some Protein Sources for Nile Tilapia (Oreochromis niloticus)ABSTRACT -A digestibility trial was carried out to determine the dry matter (MS), gross energy (EB) and crude protein (PB) apparent digestibility coefficients (CD) for fish meal (FP), poultry by-products meal (FV), gluten meal (GM) and alchool spray dried yeast (LV) for Thai Nile tilapia fingerlings. A hundred sexually reverted fishes (average weight 37.6 ± 5.0 g) were assigned to two 500-L feeding tanks and two 150-L cylindrical tanks with conical bottom, to feces collection . CD analysis was performed by the indirect method, using 0.1% chromic oxide (Cr 2 O 3 ), as marker. Average water temperature, dissolved oxygen, pH and conductivity were 25.8 ± 1.0 o C; 3.2 ± 1.4 mg/L; 6.8 ± 0.

“…For this reason, many studies have aimed to replace or reduce FM inclusion in diets by less expensive alternative protein sources, such as algae (Kiron et al 2012), bacteria (Aas et al 2006), plants (Gatlin et al 2007), invertebrates (Barrows and Frost 2014) and by-products (Fowler 1991). Meanwhile, soybean meal (SBM) is known to be one of the most successful replacers of FM, because of its favorable protein content and amino acid profile (McGoogan and Gatlin 1997;Kikuchi 1999), less expensive price than FM and availability (Hardy 2006). However, one of the potential problems associated with the use of SBM is the deficient levels of indispensable amino acids (viz.…”

Different levels of dietary soybean meal (SBM) as a fish meal (FM) replacer, with and without amino acid supplementation, for whiteleg shrimp, Litopenaeus vannamei reared in the biofloc system was examined in eight weeks of feeding trial. Eight experimental diets consisted of a basal diet with 0% FM replacement by SBM provided in clear sea water without biofloc system (S 0 SW), four diets replacing FM at 0% (S 0 ), 33% (S 33 ), 67% (S 67 ) and 100% (S 100 ) by SBM, and three diets replacing FM at 33% (S 33 A), 67% (S 67 A) and 100% (S 100 A) by SBM supplemented with amino acids (methionine and lysine) in the seawater biofloc system. Results of water quality analyses showed significantly lower total suspended solids and nitrate for S 0 SW group than all other treatments. Diets S 0 and S 33 A resulted in higher weight gain and specific growth rate among all groups, with no significant differences with S 33 group. In addition, whole-body protein and amino acid compositions of shrimp fed S 0 SW were lower than most biofloc groups. Haemolymph parameters showed significant differences in total protein, cholesterol and triglyceride between groups S 0 and S 0 SW. Also, superoxide dismutase activity showed a decreasing trend with increasing replacement level. In conclusion, based on these results, SBM could replace up to 33% of FM with or without amino acid supplementation in juvenile whiteleg shrimp diets reared in the biofloc system.
