Resumo

Objetivou-se determinar os valores energéticos e nutricionais das folhas de Moringa oleifera (MOL) para frangos de corte. Utilizaram-se 90 pintos machos, Cobb-500, com 14 dias de idade, distribuídos em delineamento inteiramente ao acaso, com cinco tratamentos e seis repetições de três aves. Os tratamentos consistiram de: uma dieta referência e quatro dietas com substituição de 10%, 20%, 30% e 40% da dieta referência pelas folhas de MOL. O período experimental teve duração de oito dias, utilizando-se a metodologia de coleta total de excretas. Foram determinados os valores de energia metabolizável aparente (EMA), aparente corrigida para o nitrogênio (EMAn), coeficiente de metabolizabilidade aparente da matéria seca (CMAMS), da proteína bruta (CMAPB) e da energia bruta (CMAEB). Os resultados obtidos foram submetidos à análise de variância e à análise de regressão a 5% de probabilidade. Houve efeito quadrático das variáveis à medida que a moringa era adicionada à ração referência. Na derivação das equações de regressão, o nível que proporcionou os melhores valores de EMA, EMAn e CMEB foi de 37,7% de substituição. O farelo de folhas MOL apresentou médias de 3140kcal/kg de EMA, 2845kcal/kg de EMAn, 76,92% de CMAEB, 76,63% de CMAMS e 73,42% de CMAPB.(AU)


This study aimed to determine the energy and nutritional value of the leaves of Moringa oleifera (MOL) for broilers. We used 90 male chicks, Cobb-500, with 14 days of age in a completely randomized design with five treatments and six repetitions of three birds. The treatments were: reference diet and 4 diets with substitution of 10%, 20%, 30%, and 40% of the diet by reference sheet MOL. The trial lasted eight days, using the method of total excreta collection. The apparent metabolizable energy (AME), apparent corrected for nitrogen (AMEn), apparent metabolizable coefficient of dry matter (AMCDM), crude protein (AMCCP) and gross energy (AMCGE). The results were submitted to analysis of variance and regression analysis at 5% probability. There was a quadratic effect of the variables as the moringa was added to the reference diet. In the derivation of the regression equations the level that provided the best values of AME, AMEn, AMCGE was 37.7% substitution. The leaves meal MOL presented average 3140kcal / kg of AME, 2845kcal / kg AMEn, 76.92% of AMCGE, 76.63% of AMCDM and 73.42% of AMCCP.(AU)

Resumo

Objetivou-se determinar a temperatura e o tempo de secagem por rolos rotativos, aos quais a, levedura de cana-de-açúcar é submetida que permitam seu melhor aproveitamento energético por galinhas poedeiras e frangos de corte. Para isso foram realizados três ensaios de metabolismo para determinar os valores de energia metabolizável aparente (EMA), aparente corrigida para nitrogênio (EMAn) e os coeficientes de metabolizabilidade aparente da matéria seca (CMMS) e da energia bruta (CMEB). O primeiro ensaio foi conduzido com galinhas poedeiras (E1), o segundo com frangos de corte (E2) em crescimento e o terceiro com frangos de corte em diferentes idades (E3). Nos ensaios E1 e E2 os tratamentos consistiram em uma dieta referência, milho e farelo de soja, e cinco dietas teste contendo 20% da levedura a ser testada em substituição à ração referência. As leveduras avaliadas foram secas por rolagem e submetidas aos seguintes processamentos: LevA - secagem a 107ºC por 107 segundos; LevB - 95ºC por 107'; LevC - 100ºC por 107'; LevD - 100ºC por 93' e LevE - 100ºC por 123'. No E3 determinou-se a EMA, EMAn, CMMS e CMEB da LevB com frangos de 1 a 8 dias, 14 a 22 dias e 28 a 36 dias de idade. No E1 não foram observadas diferenças nos valores de EMA, EMAn e CMEB entre as leveduras, com médias de 1.773kcal/kg, 1.733kcal/kg e 40,22%, respectivamente. Entretanto o CMMS foi maior para a LevD (50,36%). No E2 os valores de EMA (1.633kcal/kg), EMAn (1.382kcal/kg) e CMEB (32,22%) foram melhores para a LevB, porém não houve diferença significativa nos valores de CMMS (29,63%). No E3 foram encontrados valores de 2.723; 1.604 e 1.414kcal/kg para EMA; 2.366, 1.391 e 1.303kcal/kg para EMAn; 52,43%, 36,74%, e 25,64% para CMMS; e 54,37%, 33,49% e 24,96% para CMEB, nas idades de 1 a 8 dias, 14 a 22 dias e 28 a 36 dias, respectivamente.

This study aimed to determine the temperature and drying time through rotative rolls, that sugar cane yeast is subjected to in order to allow best energy utilization by laying hens and broilers. Three metabolism trials were conducted to determine the values of apparent metabolizable energy (AME) and apparent corrected for nitrogen balance (AMEn), coefficient of apparent metabolizable dry matter (CAMDM) and gross energy (CAMGE). The first experiment was conducted with laying hens (E1), the second with broilers (E2) in growth and the third with broilers at different ages (E3). In the experiments E1 and E2 the treatments consisted of a reference diet, based on corn and soybean meal, and five test diets containing 20% of the yeast to be tested. The evaluated yeasts were subjected to the following processes: Lev.A) drying at 107°C for 107 seconds; Lev.B) 95°C for 107'; Lev.C) 100ºC for 107'; Lev.D) 100°C for 93' and Lev.E) 100ºC for 123'. For the E3 group AME, AMEn, CAMDM and CAMGE were determined for the Lev.B of broilers with 1 to 8 days 14 to 22 days, and 28 to 36 days of age. In E1 there were no differences in AME, AMEn and CAMGE between yeasts, with mean of 1773kcal/kg 1733kcal/kg and 40.22%, respectively. However the CMMS was greater for Lev.D (50.36%). In E2, the AME (1633kcal/kg), AMEn (1382kcal/kg) and CAMGE (32.22%) were best for Lev.B, but there was no significant difference in the values of CAMMD (29 63%). TheE3 grouphad values of 2723kcal/kg; 1604kcal/kg and 1414kcal/kg of AME; 2366kcal/kg, 1391kcal/kg and 1303kcal/kg of AMEn; 52.43%, 36.74%, and 25.64% of CAMDM; and 54.37%, 33.49% and 24.96% of CAMGE, in the ages of 1 to 8 days, 14 to 22 days and 28 to 36 days, respectively. In conclusion, for layer hens, the yeast should be dried at 100°C for 93' or 107 seconds or 95ºC for 107' and for, broilers, it should be dried at 95°C for 107 seconds(AU)

Resumo

An experiment was conducted to determine the chemical composition and apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen balance (AMEn) values of corn, soybean meal (SBM), soybean oil (SO) and sugarcane yeast (SY) (Saccharomyces cerevisiae). A metabolism trial was performed with 120 Dekalb White laying hens at 65 weeks of age, using the method of total excreta collection. Birds were housed in metabolism cages and distributed according to a completely randomized design into five treatments with, six replicates of four birds each. The experimental period consisted of four days of adaptation and four days of excreta collection. The experimental diets included: a reference diet based on corn and SBM and four test diets containing 40% corn, 30% SBM, 10% SO or 30 % SY. The chemical compositions of the tested ingredients, expressed on "as-is" basis were: 86.9, 87.29, 87.32 and 99.5% dry matter; and 3.51, 2.08, 99.31 and 0.03 ether extract for corn, SBM, SO and SY, respectively. Corn, SBM, and SO presented 7.33, 43.61 and 24.64% crude protein, and 0.58, 5.07 and 6.77% ash, respectively; and crude fiber contents of corn and SBM were, respectively, 2.24% and 3.56%. The following AME and AMEn (kcal/kg dry matter) values were obtained: 3,801 and 3,760 kcal/kg for corn, 2,640 and 2,557 kcal/kg for SBM, 8,952 and 8,866 kcal/kg for SO, and 1,023 and 925 kcal/kg for sugarcane yeast, respectively.
