| 520 | |a Conduziram-se estes experimentos para avaliar os coeficientes de digestibilidade aparente dos nutrientes e da energia bruta da silagem ácida de resíduos da filetagem de tilápias e o desempenho produtivo da tilápia alimentada com dietas contendo (0, 10, 20, 30 e 40%) da silagem ácida em substituição à farinha de peixe. Na digestibilidade foram utilizados 200 alevinos revertidos sexualmente, com peso médio de 5,0 g e acondicionados em aquários de 40 litros. A coleta de fezes foi feita por metodologia indireta, utilizando-se 1,0% de Cr2O3 como indicador, incorporado à ração. No desempenho foram utilizados 2000 alevinos de tilápia nilótica, com peso médio inicial de 0,525g, acondicionados em hapas de 1m², dispostos em 1 viveiro escavado. As variáveis analisadas foram: ganho de peso final (GPF), consumo de ração total (CRT), conversão alimentar aparente (CAA) e acréscimo em comprimento (AC). O delineamento experimental foi o inteiramente casualizado, com cinco tratamentos e quatro repetições. Os valores de digestibilidade encontrados foram: coeficiente de digestibilidade aparente da matéria seca (CDA), 95,5%; CDA da proteína bruta, 96,7%; CDA do extrato etéreo, 97,2% e CDA da energia bruta, 95,4%. Não houve diferença significativa no consumo de ração total. Observou-se efeito quadrático para ganho de peso final, conversão alimentar aparente e acréscimo em comprimento. Conclui-se que este alimento pode ser eficientemente utilizado pela tilápia nilótica.<br<The experiments were carried out in order to evaluate the apparent digestibility coefficients of the nutrients and gross energy of acid silage of filetage residues of the Nile tilapia. 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 collect was made during seven subsequent days and the apparent digestibility coefficients and apparent digestible energy were determined by indirect method, using 1.0% of Cr(2)0(3) as an indicator. In the performance assay 2000 sexually inverted juveniles were used, with average weight of 0.45g, kept in 1m² hapas, in a fish crawl. The analyzed variables were: final weight (FWG), total feed intake (TFI), apparent feed conversion (AFC) and length increase (LI). The randomized outline was used with five treatments and four repetitions. The values for apparent digestibility were: apparent digestibility coefficient of dry matter, 95.49%; apparent digestibility coefficient of gross protein, 96.66%; apparent digestibility coefficient of ether extract, 97.18%; apparent digestibility coeficient of gross energy, 95.44%. There was no significant difference (P<0.05) for total feed intake (TFI). One observed a quadratic effect (P<0.01) in the final weight (FWG), apparent feed conversion (AFC) and length increase. One concluded that the acid silage of filetage residues should be efficiently used by the Nile tilapia. | ||

The randomized outline was used with five treatments and four repetitions. The values for apparent digestibility were: apparent digestibility coefficient of dry matter, 95.49%; apparent digestibility coefficient of gross protein, 96.66%; apparent digestibility coefficient of ether extract, 97.18%; apparent digestibility coeficient of gross energy, 95.44%. There was no significant difference (P<0.05) for total feed intake (TFI). One observed a quadratic effect (P<0.01) in the final weight (FWG), apparent feed conversion (AFC) and length increase. One concluded that the acid silage of filetage residues should be efficiently used by the Nile tilapia.

Desempenho produtivo e digestibilidade pela tilápia do NILO (Oreochromis niloticus Linnaeus, 1758) alimentada com dietas suplementadas com níveis crescentes de silagem ácida de pescado Yielo and digestibility performance by the Nile tilapia (Oreochromis niloticus Linnaeus, 1758) fed with diets with increasing levels of acid silage of fishing |
| abstract |
Conduziram-se estes experimentos para avaliar os coeficientes de digestibilidade aparente dos nutrientes e da energia bruta da silagem ácida de resíduos da filetagem de tilápias e o desempenho produtivo da tilápia alimentada com dietas contendo (0, 10, 20, 30 e 40%) da silagem ácida em substituição à farinha de peixe. Na digestibilidade foram utilizados 200 alevinos revertidos sexualmente, com peso médio de 5,0 g e acondicionados em aquários de 40 litros. A coleta de fezes foi feita por metodologia indireta, utilizando-se 1,0% de Cr2O3 como indicador, incorporado à ração. No desempenho foram utilizados 2000 alevinos de tilápia nilótica, com peso médio inicial de 0,525g, acondicionados em hapas de 1m², dispostos em 1 viveiro escavado. As variáveis analisadas foram: ganho de peso final (GPF), consumo de ração total (CRT), conversão alimentar aparente (CAA) e acréscimo em comprimento (AC). O delineamento experimental foi o inteiramente casualizado, com cinco tratamentos e quatro repetições. Os valores de digestibilidade encontrados foram: coeficiente de digestibilidade aparente da matéria seca (CDA), 95,5%; CDA da proteína bruta, 96,7%; CDA do extrato etéreo, 97,2% e CDA da energia bruta, 95,4%. Não houve diferença significativa no consumo de ração total. Observou-se efeito quadrático para ganho de peso final, conversão alimentar aparente e acréscimo em comprimento. Conclui-se que este alimento pode ser eficientemente utilizado pela tilápia nilótica.<br<The experiments were carried out in order to evaluate the apparent digestibility coefficients of the nutrients and gross energy of acid silage of filetage residues of the Nile tilapia. 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 collect was made during seven subsequent days and the apparent digestibility coefficients and apparent digestible energy were determined by indirect method, using 1.0% of Cr(2)0(3) as an indicator. In the performance assay 2000 sexually inverted juveniles were used, with average weight of 0.45g, kept in 1m² hapas, in a fish crawl. The analyzed variables were: final weight (FWG), total feed intake (TFI), apparent feed conversion (AFC) and length increase (LI). The randomized outline was used with five treatments and four repetitions. The values for apparent digestibility were: apparent digestibility coefficient of dry matter, 95.49%; apparent digestibility coefficient of gross protein, 96.66%; apparent digestibility coefficient of ether extract, 97.18%; apparent digestibility coeficient of gross energy, 95.44%. There was no significant difference (P<0.05) for total feed intake (TFI). One observed a quadratic effect (P<0.01) in the final weight (FWG), apparent feed conversion (AFC) and length increase. One concluded that the acid silage of filetage residues should be efficiently used by the Nile tilapia. |

In the performance assay 2000 sexually inverted juveniles were used, with average weight of 0.45g, kept in 1m² hapas, in a fish crawl. The analyzed variables were: final weight (FWG), total feed intake (TFI), apparent feed conversion (AFC) and length increase (LI). The randomized outline was used with five treatments and four repetitions. The values for apparent digestibility were: apparent digestibility coefficient of dry matter, 95.49%; apparent digestibility coefficient of gross protein, 96.66%; apparent digestibility coefficient of ether extract, 97.18%; apparent digestibility coeficient of gross energy, 95.44%. There was no significant difference (P<0.05) for total feed intake (TFI). One observed a quadratic effect (P<0.01) in the final weight (FWG), apparent feed conversion (AFC) and length increase. One concluded that the acid silage of filetage residues should be efficiently used by the Nile tilapia.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
