Abstract: the study was carried out with the objective to evaluate the effects of the inclusion of the wheat bran (wb) with or without supplementation of an enzymatic complex (ec) on the performance of semi-heavy hens in the egg-production phase. a total of 288 lohmann brown pullets were used, distributed to a completely randomized design in 4 × 2 factorial arrangement, composed by four wb levels (0, 3, 6 and 9%) in the ration and enzymatic complex supplementation (0 or 100g/100 kg diet), with eight treatments and six replicates of six birds. the enzymatic complex contained the enzymes b-galactosidase, galactomananase, xilanase and a-glucanase. feed intake, final body weight, egg production, egg weight, egg mass, egg mass feed conversion or egg dozen feed conversion was not affected by wb inclusion in the diets. egg shell specific gravity deteriorated as wb levels increase in the diets. none of the characteristics was affected by the enzymatic complex supplementation, except for egg weight, that improved from 62.74 to 64.28 g. then, the use up to 9.0% of wheat bran in the ration is recommended for semi-heavily chickens in the production phase. the supplementation of a-galactosidase, galactomannanase, xylanase and a-glucanase improve egg weight.

Revista Brasileira de Saúde e Produ??o Animal , 2011,
Abstract: This study aimed to evaluate growth performance and economic viability of tambaqui fed different levels of coconut husk meal (0;25;50 and 100). Thus, a 60-day feeding trial was performed to evaluate the effect of dietary graded levels of coconut husk meal on growth performance of tambaqui (Colossoma macropomum) and economic viability. One hundred and twenty tambaqui fingerlings with 7.71±0.17g were randomly assigned to 24 150L-aquaria in a completely randomized experimental design with four treatments and six replication. Diets were formulated to contain the same content of protein (26% CP), digestible energy (3200kcal DE/kg diet) and crude fiber (8.51%) differing only on the coconut husk meal replacement levels which were 0% (control diet), 25, 50 and 100%. Although no effect of coconut husk meal inclusion were observed for daily weight gain, daily feed intake, feed conversion ratio, specific growth rate, protein efficiency ratio and fillet yield, a negative and positive linear regression was significant for hepatossomatic and fat visceral indexes, respectively. The use of coconut husk meal in diets for tambaqui did not affect growth performance and carcass quality parameters. However, it is recommended the replacement of soybean meal to coconut husk meal up to 25% based on the economic evaluation of the diets. Avaliou-se com este trabalho o desempenho produtivo e econ mico do tambaqui alimentado com ra es que continham 0, 25, 50 e 100% de farelo de coco em substitui o ao farelo de soja. O experimento foi realizado em delineamento inteiramente casualizado com quatro tratamentos e seis repeti es, para avaliar o efeito de dietas com níveis crescentes de farelo de coco sobre o desempenho do tambaqui (Colossoma macropomum), características de carca a e na viabilidade econ mica. Foram utilizados 120 alevinos com peso médio inicial de 7,71±0,17g distribuídos aleatoriamente em 24 aquários de 150L. As dietas formuladas foram isoprotéicas (26% PB), isoenergéticas (3.200kcal ED/kg de ra o), e isofíbrilicas (8,51%) com diferen a apenas nos níveis de substitui o do farelo de soja pelo farelo de coco, que foram 0(controle), 25, 50 e 100%. N o houve diferen a significativa entre os tratamentos para o ganho em peso diário, consumo diário de ra o, convers o alimentar aparente, taxa de crescimento especifico, taxa de eficiência protéica e rendimento de filé. Diferente dos resultados obtidos para índice hepatossomático e índice de gordura visceral os quais apresentaram regress o linear negativa e positiva, respectivamente.

Abstract: Replacement of conventional ingredients used in fish diets by non-conventional products has been an economic alternative to reduce the cost of feeding. Therefore, 90-day trial was performed to study the effect of shrimp meal (SM) inclusion on diets of Nile tilapia fries. Weight gain (WG), feed conversion (FC), apparent feed intake (AFI), fillet yield (FY), fillet income (FI) values and protein effiency ratio (PER) were evaluated. Each experimental unit was an aquaria with five tilapias (Oreochromis niloticus), mean body weight of 7,9g, total of 120 animals. Treatments were four diets with 0, 25, 50 and 100% of SM replacing the soybean meal, which protein (28.0%) and energy (3100 kcal/DE/kg) content in diet were similar. Animals were fed three times daily. The offered food was adjusted according to fish live weight. The substitution of soybean by SM reduced WG, FC, AFI, FY and PER. SM inclusion did not affect the FI. Shrimp meal inclusion in diets for Nile tilapia affects negatively the growth performance. O objetivo deste estudo foi testar a inclus o da farinha de camar o (FC) em dietas para a tilápia do Nilo. O desempenho dos animais foi avaliado através do ganho de peso (GP), convers o alimentar aparente (CAA), consumo de ra o aparente (CRA), peso de filé (PF), rendimento de filé (RF) e taxa de eficiência protéica (TEP). O delineamento utilizado no experimento foi em blocos casulaizados distribuídos em 24 caixas de polietileno com capacidade de 150 L supridas por sistema de recircula o fechada de água (0,2L/min.) durante 90 dias. Cada unidade experimental era composta por um aquário com cinco tilápias (Oreochromis niloticus) com peso médio inicial de aproximadamente 7,9g perfazendo um total de 120 animais. Os tratamentos constituíram-se de quatro ra es contendo 0, 25, 50 e 100% de FC em substitui o ao farelo de soja, sendo estas isoprotéicas (28,0%PB) e isoenergéticas (3100 kcal de EB/kg). Os animais foram alimentados três vezes ao dia com a quantidade de ra o fornecida ad libitum. A farinha de camar o pode substituir a proteína do farelo de soja até 50% de inclus o sem comprometer o ganho de peso, convers o alimentar e peso do filé.

Abstract: To evaluate the productive and economic viability of coconut meal (FC) and enzymatic complex (E) inclusion in diets for growing pigs, it were used 20 homogenous barrows with average weight of 31.15 ± 5.59kg. The animals were distributed in a randomized block design with four treatments, and five replicates each, with an animal as experimental unit. The experimental treatments were: 0%FC – control diet, a corn-soy diet; 20%FC- control diet added of 20% of coconut meal (FC); 20%FC+0,05E – control diet added of 20% of coconut meal, plus 0,05% of enzymatic complex, and 20%FC+0,10E – control diet added of 20% of coconut meal, plus 0,10% of enzymatic complex. Experimental diets had the same level of nutrients. At the end of experimental period, blood samples were taken from each animal. Results demonstrated that coconut meal and enzymatic complex inclusion did not affect the performance and serum parameters of animals, except HDL fraction of cholesterol. In conclusion, the addition of 20% of coconut meal, added or not by enzymatic complex, did not affect the performance of the animals, but the inclusion of 20% of coconut meal without enzymatic complex resulted in economical efficiency. Com o objetivo de avaliar a viabilidade produtiva e econ mica da inclus o do farelo de coco (FC) e complexo enzimático (E) em dietas para suínos na fase de crescimento, utilizaram-se 20 suínos machos castrados de mesma linhagem, com peso médio de 31,15 ± 5,59kg. Os animais foram distribuídos em um delineamento em blocos casualizados com quatro tratamentos, de cinco repeti es cada, com um animal por unidade experimental. Os tratamentos foram: 0%FC - dieta constituída principalmente por milho, farelo de soja; 20%FC- dieta com inclus o de 20% de farelo de coco (FC); 20%FC+0,05E - dieta com inclus o de 20% FC e adi o de 0,05% do complexo enzimático e 20%FC+0,10E - dieta com inclus o de 20% FC e adi o de 0,10% do complexo enzimático. As dietas experimentais foram isonutritivas. Ao final do período experimental, foram colhidas amostras de sangue. Os resultados demonstraram que a inclus o do farelo de coco, e as enzimas n o influenciaram o desempenho produtivo e os parametros séricos, com exce o da fra o HDL do colesterol. Conclui-se que a inclus o de 20% farelo de coco, com ou sem complexo enzimático, n o influenciou o desempenho dos animais, porém a inclus o de 20% do farelo de coco sem adi o de enzimas proporcionou uma melhor eficiência econ mica.

Abstract: Este estudo foi conduzido com o objetivo de avaliar o efeito dos taninos sobre o desempenho produtivo e a composi o da carca a do piau u. Utilizaram-se 21 aquários (80 L) num sistema de fluxo fechado com circula o continua (vaz o de 1 L/min), filtro biológico e temperatura controlada. Empregaram-se 84 peixes com peso médio inicial de 5,06 g, na densidade de quatro por aquário, num delineamento inteiramente casualizado com sete tratamentos e três repeti es. As ra es foram formuladas de forma a apresentarem-se isoenergéticas (3200 kcal ED/ kg de ra o) e isoprotéicas (30% PB), com as seguintes composi es de tanino total: 0,00; 0,23; 0,46; 0,69; 0,92; 1,37 e 1,82. Avaliou-se a influência do tanino sobre o desempenho produtivo: ganho de peso, convers o alimentar aparente e taxa de eficiência protéica; a composi o corporal dos peixes: proteína bruta da carca a, extrato etéreo da carca a, proteína bruta e extrato etéreo dos fígados e gordura visceral; e a rela o hepatossomática: índice hepatossomático. Concluiu-se que, embora a presen a de até 0,69% de taninos na ra o n o tenha comprometido os índices de convers o alimentar aparente e taxa de eficiência protéica das ra es, níveis iguais ou superiores a 0,46% resultaram em ganho de peso significativamente inferior para o piau u e que a espécie se mostrou sensível à presen a de taninos condensados, os quais prejudicaram significativamente o metabolismo e o valor biológico dos nutrientes presentes nas ra es.

Abstract: Este estudo foi realizado para determinar a energia digestível e a digestibilidade aparente de nutrientes do farelo de canola pela tilápia do Nilo (Oreochromis niloticus). O óxido de cr mio (0,1%) foi utilizado como indicador inerte em dieta semi-purificada, com coleta de fezes pelo sistema Guelph. Os peixes foram alimentados até saciedade aparente. O farelo de canola apresentou valores de energia e nutrientes digestíveis de: 77,84; 71,99; 86,92; 88,19; 67,16 e 29,86% para a matéria seca, energia, proteína, lipídios, cálcio e fósforo, respectivamente, correspondendo a 2969,98 (kcal/kg); 69,97; 32,6; 1,2; 0,41 e 0,28%, de energia digestível, matéria seca, proteína e lipídios digestíveis e cálcio e fósforo disponíveis, respectivamente. Os resultados obtidos neste trabalho evidenciam que a tilápia do Nilo pode utilizar eficientemente o farelo de canola.
