“…Small variations were observed in the energy content of the tested feedstuffs (Table 2) relative to literature reports (Brito et al, 2005;Generoso et al, 2008;Mello et al, 2009). 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).…”

“…In order to formulate economically viable feeds, it is important to know the nutritional value of feedstuffs, which requires determining their chemical composition, nutrient availability, and energy content and utilization by a given species (Generoso et al, 2008). Although feedstuffs are often evaluated for fast-growing chickens, few studies have been performed to determine feed nutrient utilization by slowgrowing chicken strains reared in alternative animal production systems.…”

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.

“…Seerley et al (1974) tested different temperatures of extracting oil from sunflower seed and reported that the lysine content was greater at 100°C than that found at 127ºC. At high temperatures, the epsilon group of lysine binds to a carbohydrate and this makes it less available amino acids (HERKELMAN; CROMwELL, 1990), suggesting that the limitation of lysine for the cake could be smaller due to the fact that the mechanical process does not use high temperatures as in solvent extraction.…”

Nutritional and energy values of sunflower cake for broilers

The study aimed to determine the nutritional and energy values of sunflower cake for broilers through two experiments. The first study evaluated the energy values by the method of total excreta collection, using 100 broiler chicks 21-31 days old, divided into five treatments of 0%, 10%, 20%, 30% and 40% inclusion sunflower cake will reference a diet. The second experiment evaluated the influence of the period and the quantity supplied of sunflower cake on digestibility of amino acids by a forcedfeeding technique. Eighteen cockerels were used, divided into three treatments, which consisted of supplying 15 g of sunflower cake, 30 g of sunflower cake (15 g at intervals of 12 hours) and 30 g of sunflower cake (15 g at intervals of 24 hours), and an additional six roosters were fasted for correction of metabolic and endogenous losses. The samples were sent for amino acid analysis by HPLC in the Evonik Laboratory (Germany), and chemical and energy analysis to Unioeste Laboratory. The values of apparent metabolizable energy (AME), metabolization coefficient (AMC), apparent metabolizable energy corrected for nitrogen balance (AMEn), metabolization coefficient corrected for nitrogen balance (AMCn) for sunflower cake were 2211.68 kcal.kg -1 , 2150.54 kcal.kg -1 , 45.47% and 44.73%, respectively. The amount of food provided in the feeding method changed the assessment of true digestibility of amino acids (TDCA), and when only 15 g was used, the values of true digestibility coefficients were underestimated. The lysine, histidine and threonine amino acids were at lower TDCA, and arginine and methionine showed the highest TDCA for sunflower cake.

“…O nível de MS do FAI (88,6%) foi semelhante aos valores citados por CONTE et al (2002) ROSTAGNO et al (2005). A QA apresentou 9,11% de PB, valor superior aos valores encontrados na literatura, ou seja, LIMA et al ROSTAGNO et al (2000) e GENEROSO et al (2008). Tais diferenças podem estar associadas à composição química dos subprodutos do arroz, já que a energia metabolizável do alimento é um produto resultante da transformação dos nutrientes, sendo afetada direta e positivamente pela composição do alimento em carboidratos de reserva, gordura, proteína e negativamente pelos carboidratos estruturais (CONTE et al, 2002).…”

Dois experimentos foram conduzidos para determinar a composição química, os valores de energia e os coeficientes de digestibilidade dos aminoácidos, do farelo de arroz integral (FAI) e da quirera de arroz (QA). No primeiro estudo, foram utilizadas 144 aves, com 21 dias de idade, machos, linhagem Cobb, que tiveram suas excretas totalmente coletadas para determinação da energia metabolizável aparente (EMA) e energia metabolizável aparente corrigida (EMAn). O delineamento experimental foi inteiramente casualizado, com três tratamentos e seis repetições, com oito aves cada. No segundo experimento, foi utilizado o método de alimentação forçada para a determinação dos coeficientes de digestibilidade dos aminoácidos. O delineamento foi inteiramente casualizado, com dois alimentos e um jejum e seis repetições com um galo cada. Os valores de MS, PB, EE, FB, EMA e EMAn foram, respectivamente, para FAI: 88,6%; 11,8%; 15,3%; 10,2%; 2968kcal kg-1 e 2804kcal kg-1 e para QA: 93,5%; 9,1%; 0,73%; 0,45%; 3338kcal kg-1 e 3239kcal kg-1. Os valores médios encontrados dos coeficientes de digestibilidade de aminoácidos essenciais e não essenciais foram, respectivamente, de 75,9% e 73,9%, para FAI, e 77,9% e 76,5%, para QA. Embora tenham apresentado níveis inferiores de energia, FAI e a QA podem ser utilizados nas rações de aves em substituição ao milho, uma vez que tiveram níveis maiores de proteína bruta e aminoácidos digestíveis.
