“…Espe et al (1999) reported a similar effect for low inclusion levels (15%) using fish silage in Atlantic salmon diets. Also, Plascencia-Jatomeaet al (2002) found that, replacing FM by shrimp head silage in the Nile tilapia diets up to 15% showed the best response in growth performance, while the higher replacing levels (20, 25 or 30%) resulted in the worst growth response.…”

A feeding trial was conducted to study the possibility of replacing the fish meal (FM) with fermented fish by-product silage (FBS) as non-conventional ingredients in the diets of the Nile tilapia, Oreochromis niloticus fingerlings. Five isonitrogenous (300 g CP kg -1 dry matter, DM) and isocaloric (19 MJ gross energy kg -1 DM) diets were formulated and FM was replaced by FBS in five increased levels, 0, 25, 50, 75 and 100% g to formulate the five experimental diets, FBS0, FBS25, FBS50, FBS75 and FBS100, respectively. Three hundred O. niloticus fingerlings (18.53±0.70g) were randomly distributed into 15 glass aquaria (160 liter), and were divided into five groups (three aquaria for each group) and each aquarium holding 20 fish. Experimental fish were fed onon the formulated diets for 84 days. Replacing of FM with FBS up to 25% did not significantly (P<0.05) affected growth and feed utilization parameters, while the other substitution levels (50,75 or 100%) significantly (P<0.05) reduced growth and feed utilization parameters. Fish offered the control diet exhibited the highest significance (P<0.05) average body weight (BW), body length (BL), weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER). Fish group fed onon FBS25 gained the highest significant protein content and the lowest fat and ash content of carcasses compared to the control and the other fish groups Generally, replacing 25% of FM by FBS did not significantly affected growth and feed utilization parameters and reduced feed costs by 7.93% for tilapia fingerlings.

“…According to Baldisserotto (2013), the inclusion of hydrolyzed protein diets for fish larvae can be beneficial until a certain percentage, because they are more readily absorbed by the enterocytes, due to stimulate the activity of intracellular peptidases and thus facilitating the assimilation of the amino acids. However, the absorption of nutrients and the productive performance of the animals can be affected by the inclusion of high percentages of hydrolysates in the diet, fact that was found by Espe, Sveier, Høgøy, and Lied (1999) and Hevroy et al (2005). They evaluated different levels of fish hydrolysates for the Atlantic salmon (Salmo salar) and found a decrease in productive performance of animals fed with high levels of the test ingredient.…”

“…Moreover, the high amount of these nutrients in the intestine increases absorption, blood plasma concentration and consequently, its catabolism. Both by increasing the degradation of newly synthesized proteins as well as by the oxidation of amino acids, since they cannot be stored in the tissues, making them unavailable for the synthesis of new proteins (Espe, Sveier, Høgøy, & Lied, 1999;Hevroy et al, 2005). Bui et al (2014) evaluated the replacement of fishmeal by different types of hydrolysates, being present the dry protein hydrolysate of tilapia processing residue in Pagrus major diets, and they reported positive effect on animal performance in relation to the final weight, specific growth and efficiency protein rate.…”

ABSTRACT. This study aimed to evaluate the digestibility of tilapia by-product protein hydrolysate powder (TBHP) from tilapia filleting by-product, and its inclusion in diets for Nile tilapia larvae. In order to determine the apparent digestibility coefficients, two diets were formulated, the reference diet and the test diet (20% of TBHP) and, to evaluate the inclusion, six diets were formulated, which were with 0.0, 2.0; 4.0; 6.0, and 8.0% of TBHP. The apparent digestibility coefficients of crude protein and gross energy were 89.5 and 98.3%, respectively. At levels above 4.0% of inclusion of TBHP, the weight, final length and weight gain were impaired, however, survival rate was higher (p < 0.05). The TBHP can be used in diets for tilapia due to the high digestibility coefficients for crude protein and gross energy. The inclusion of up to 4.0% of TBHP does not affect the reproductive performance and survival rate of Nile tilapia larvae.Keywords: digestibility, fish nutrition, performance.Hidrolisado proteico seco do resíduo da filetagem de tilápias em dietas para larvas de tilápia do Nilo RESUMO. Objetivou-se avaliar a digestibilidade do hidrolisado proteico seco do resíduo da filetagem de tilápias (HPST) e sua inclusão em dietas para larvas de tilápia do Nilo. Para determinar os coeficientes de digestibilidade aparente, duas dietas foram elaboradas, referência e teste (com 20% do HPST) e para avaliação da inclusão, seis dietas foram formuladas com 0,0, 2,0; 4,0; 6,0, e 8,0% de HPST. Os coeficientes de digestibilidade aparente da proteína e energia bruta foram de 89,5 e 98,3%, respectivamente. Nos níveis acima de 4,0% de inclusão de HPST o peso e comprimento final e ganho em peso foram prejudicados, no entanto a sobrevivência foi maior (p < 0,05). O HPST pode ser utilizado em dietas para tilápias em função dos elevados coeficientes de digestibilidade para proteína bruta e energia bruta. A inclusão de até 4,0% de HPST não afeta o desempenho produtivo e a sobrevivência de larvas de tilápias do Nilo.Palavras-chave: digestibilidade, nutrição de peixes, desempenho.

“…Estes dados são compatíveis com os relatados por Ramos et al (2001) que, trabalhando com alevinos de cachama negra (Colossoma macropomum), avaliaram duas dietas (uma com 18% de proteína bruta de silagem de pescado e uma com 22% de proteína bruta de farinha de peixe) e observaram que os peixes alimentados com silagem de peixe e farinha de peixe ao final do experimento apresentaram peso e conversão alimentar semelhantes, sem diferenças significativas. Espe et al (1999), em estudos realizados com ratos utilizando dietas suplementadas com silagem de pescado na proporção de 6 a 8%, não verificaram nenhuma influência sobre o consumo. Em suínos nas fases de crescimento e terminação, Green (1984) verificou que o aumento do nível de silagem de peixe (0, 2, 5 e 8%) nas rações e o ganho de peso diário e conversão alimentar não foram similares em todos os tratamentos em relação à dieta consumida.…”

RESUMOOs experimentos foram conduzidos para avaliar os coeficientes de digestibilidade aparente dos nutrientes e da energia bruta da silagem ácida de resíduos da filetagem de tilápia do Nilo (Oreochromis niloticus) para alevinos de tilápia nilótica e o desempenho dos alevinos recebendo níveis crescentes (0, 10, 20, 30, 40 %) da silagem ácida em substituição à farinha de peixe na ração. Na digestibilidade foram utilizados 200 alevinos revertidos sexualmente, com peso médio de 2,0 g e acondicionados em aquários de 40 litros. A coleta de fezes foi feita durante 7 dias seguintes e a determinação dos coeficientes de digestibilidade aparente e energia metabolizável aparente foi feita por metodologia indireta, tendo sido utilizado 1% de Cr 2 O 3 como indicador incorporado à ração. No desempenho, foram utilizados 2000 alevinos revertidos sexualmente com peso médio de 0,45 g, acondicionados em hapas de 1m 2 , dispostos em um viveiro escavado. As variáveis analisadas foram: ganho de peso final (GPF), consumo de ração total (CRT), conversão alimentar aparente (CAA), acréscimo em altura (AA) e em comprimento (AC). O delineamento utilizado foi o inteiramente casualizado, com 5 tratamentos e 4 repetições. Os valores de digestibilidade encontrados foram: coeficiente de digestibilidade aparente da matéria seca, 95,49%; coeficiente de digestibilidade aparente da proteína bruta, 96,66%; coeficiente de digestibilidade aparente do extrato etéreo, 97,18%; coeficiente de digestibilidade aparente da energia bruta, 95,44%, e energia digestível aparente 2.880,02 kcal/kg. Não houve diferença significativa (P> 0,05) para ganho de peso final, consumo de ração total, conversão e acréscimo em altura. Observou-se aumento linear (P<0,01) para o comprimento. Conclui-se que este alimento pode ser eficientemente utilizado pela tilápia nilótica.Termos para indexação: Digestibilidade, Tilápia do Nilo, desempenho, ração alternativa. ABSTRACTThe experiments were carried out in order to evaluate the apparent digestibility coefficients of the nutrients and gross energy of acid silage of filetage residues from Nile tilapia (Oreochromis niloticus). This silage was given to Nile tilapia juvenile and their performance was taken. The treatments were based on the increasing levels (0, 10, 20, 30, 40%) of the acid silage by substitution of fish meal in the diets. In the digestibility assay a total of 200 sexually inverted juveniles were used. The average weight was 2.0 g and were kept in 40 liter aquariums. Feces collection was made during 7 subsequent days and the apparent digestibility coefficients and apparent metabolizable energy were determined by indirect method, 1% of Cr 2 0 3 was used as an indicator . In the performance assay a total of 2000 sexually inverted juveniles were used. The average weight of 0.45g, they also were kept in 1m 2 hapas in a fish crawl. The analyzed variables were: final weight (FWG), total feed intake (TFE), apparent feed conversion (AFC), height increase (HI) and length increase (LI). The randomized design was used with 5 trea...
