“…Total amino acids content of the tested feedstuffs (Table 3) were consistent with those observed by Freitas et al (2005) and Rostagno et al (2011). According to Calderano et al, (2010), variations in the chemical and energy composition of feedstuffs may occur for several reasons, such as differences in cultivar, as well as growth, soil, and weather conditions and processing to which the source material is exposed.…”

Two trials were performed to determine apparent metabolizable energy (AME) and AME corrected for zero nitrogen balance (AMEn) values and coefficients of apparent metabolizability of nitrogen (CAMN) and of ether extract (CAMEE) of slow-and fast-growing broilers (Isa label and Cobb, respectively) fed four different diets between 10 to 17 days or 28 to 35 days of age. The method of total excreta collection was applied. The tested feedstuffs were corn, whole corn germ (WCG), sorghum, and soybean meal (SBM). A randomized block experimental design was applied, with two treatments (breeds) and four replicates of ten animals each in the first trial, and four replicates of six animals each in the second trial. No differences in CAMN values were observed between the breeds; however, Isa Label birds presented higher CAMEE for all tested feedstuffs. The AME and AMEn values obtained in Isa Label chickens fed the corn diet were 5.75 and 3.44% higher relative tothe Cobb birds, respectively. Breed did not influence AME and AMEn values of the other tested feedstuffs. Independently of breed, age influenced the AME and AMEn values of WCG, sorghum and SBM, suggesting that birds become utilize feed more efficiently as they age.

“…According to Calderano et al (2010) and González-Alvarado et al (2007), decreased WG and FI levels with increased DRC inclusion levels may be related to the increased fibre content in the diet, combined with the low digestion capacity, as well as the sensation of satiety caused by the fibre.…”

The objective of this study was to evaluate the inclusion of dry residue of cassava (DRC) with or without supplementation of carbohydrases on performance, carcass yield, cuts and organs, blood parameters and meat quality of broiler chickens. Birds were distributed in a completely randomised design in a 2 x 5 factorial scheme, with or without addition of carbohydrases and five levels of DRC inclusion, resulting in 10 treatments with 5 replicates of 22 birds each. At 21 days of age, two birds of each treatment were fasted for 6 hours for blood brachial puncture. At 42 days, four birds per pen were slaughtered to determine carcass yield, cuts, organs, percentage of abdominal fat and meat quality. Between 1-21 days of age, there was an interaction (P < 0.05) between carbohydrase and DRC supplementation on weight gain (WG) and feed intake, which showed a decreasing linear effect without the inclusion of carbohydrases. In the period from 1 to 42 days, there was an interaction (P < 0.05) between carbohydrase supplementation and DRC inclusion on the variables WG and feed conversion. Carbohydrase inclusion provided an increase (P < 0.05) in the concentrations of cholesterol, triglycerides, creatinine, gamma GT and blood glucose. Concentrations of gamma GT were increased and levels of alanine aminotransferase and creatinine were decreased (P < 0.05) with DRC inclusion. At 24 hours post mortem, there was a significant interaction (P < 0.05) for breast meat between carbohydrase supplementation and DRC inclusion for the variable L. The analysed values of pH, water holding capacity and shear force of the breast meat were not affected (P > 0.05) by DRC inclusion and carbohydrase addition. However, cooking loss was influenced (P < 0.05) by levels of inclusion of DRC. The L and a* variable and the feet of broiler chickens were not affected (P > 0.05) by DRC levels and carbohydrase addition. The colour variable b* showed a decrease (P < 0.05) from 5% level of inclusion. The results of this study show that DRC can be used in the diets of broiler chickens from 1 to 21 days old to the assessed level of 10%, provided that carbohydrase is added. ResumoO objetivo do trabalho foi avaliar a inclusão do resíduo seco de fecularia (RSF) com ou sem a suplementação de carboidrases sobre o desempenho, o rendimento de carcaça, cortes e órgãos, parâmetros sanguíneos e qualidade da carne de frangos de corte. As aves foram distribuídas em um delineamento inteiramente casualizado, em esquema fatorial 2x5, constituído da combinação da adição ou não de carboidrases e cinco níveis de inclusão de RSF, resultando em 10 tratamentos, com cinco repetições de 22 aves cada. Aos 21 dias de idade, duas aves por unidade experimental foram mantidas em jejum por 6 horas, para coleta de sangue via punção braquial. Aos 42 dias de idade, quatro aves por unidade experimental foram abatidas para determinação do rendimento de carcaça, cortes, órgãos, porcentagem de gordura abdominal e avaliação da qualidade da carne. No período de 1 a 21 dias de idade houve in...

“…In the present study, the apparent metabolizable energy of the feed containing acid silage flour made of pirarucu waste was 3253.01 kcal kg -1 , that is, close to the values reported in the literature. (Calderano et al, 2010), and its better use by birds. In this way, the nutritional evaluation of alternative foods with poultry intended for egg production represents an investigative action of great technical and scientific value, since in many cases it is not fully used due to the scarcity of regional diversity (Melo et al, 2015).…”

ABSTRACT. The objective of this study was to evaluate the effects of acid silage meal made of pirarucu waste in diets for commercial laying hens on apparent digestibility and energy metabolism. Seventy-two Hisex White hens with 71 weeks of age were assigned to a completely randomized with two treatments (control diet and diet with 3% pirarucu waste acid silage) with six replicates of six birds each. phosphorus. Differences (p > 0.05) were detected in digestibility of crude protein, non-fiber carbohydrates (soluble carbohydrates), etherextract, mineral matter, metabolizable energy and metabolizable energy coefficient. Our results indicate that the acid silage mealmade of pirarucu waste can be included up to 3% in diets for laying hens, showing satisfactory nutrient digestibility and potential to be used as an energy source.Keywords: alternative food, fish waste, metabolizable energy, nutrients, silage.Características físico-química e digestibilidade da farinha de silagem ácida de resíduo de pirarucu em rações de poedeiras comerciais leves RESUMO. Objetivou-se com este estudo avaliar as características físico-químicas e nutricionais da farinha de silagem ácida de resíduos de pirarucu em rações para poedeiras comerciais leves sobre a digestibilidade aparente e metabolização energética. Foram utilizadas 72 poedeiras da linhagem Hisex White com 71 semanas de idade distribuídas em um delineamento inteiramente casualizado com seis repetições de seis aves cada. Os tratamentos foram constituídos pelo controle (sem inclusão do produto) e a ração experimental (com 3% de inclusão de silagem ácida). A biomassa ensilada apresentou coloração marrom claro; aroma levemente acidificado; consistência ligeiramente cremosa; pH de 4,38±0,11; com valores de 84,16% de matéria seca; 40,06% de proteína bruta; 26,82% de extrato etéreo; 9,31% de matéria mineral, 65,16 g kg -1de cálcio e 22,90 g kg -1de fósforo. Foram observadas diferenças significativas na digestibilidade da proteína bruta, extrato não nitrogenado (carboidratos solúveis), extrato etéreo, matéria mineral, energia metabolizável e no coeficiente de metabolização da energia metabolizável. Os resultados do presente estudo indicaram que a silagem ácida produzida a partir da biomassa residual do pirarucu pode ser incluída na forma de farinha até 3% em rações para poedeiras leves, apresentando boa digestibilidade dos nutrientes e potencial para ser utilizada como fonte energética.Palavras-chave: alimento alternativo, ensilado, energia metabolizável, nutrientes, resíduo de pescado.
