“…Compared with cereal grains (NRC 1994), canola meal (Askbrant 1988;Simbaya 1995) and soybean meal (Askbrant 1988;NRC 1994), the mean nitorgen-corrected metabolizable energy value (12.2 ± 0.54 MJ kg -1 ) (TME n ) of these cultivars is comparable to that of barley, higher than that of canola meal and soybean meal, but lower than that of wheat. Based on the energy values obtained in the present study, peas can provide a significant portion of the energy requirement of poultry.…”

“…The data provided by Savage and Deo (1989) gave a range of 12.31 to 15.63 MJ kg -1 values for TME and 10.09 to 12.83 MJ kg -1 values for TME n of raw peas. Also, Askbrant (1988) evaluated samples of white-flowered peas and reported a range of 12.48 to 15.60 MJ kg -1 values for TME. The TME and TME n values obtained in the present study are in agreement with those given by these authors.…”

Field peas: Chemical composition and energy and amino acid availabilities for poultry. Can. J. Anim. Sci. 77: 293-300. Twelve pea cultivars (yellow-, green-and brown-seeded) were evaluated for chemical composition and digestibility in poultry. The evaluation involved analyses for protein, amino acids (AAs), fat, starch, dietary fibre, ash, calcium, phosphorus and tannins. True metabolizable energy [nitrogen corrected (TME n ) and uncorrected (TME)] and true AA bioavailability values were also determined with adult cockerels. The cultivars showed a wide range of protein (207.5-264.0 g kg -1 ) and starch (385.3-436.8 g kg -1 ) contents which were not related to the seed coat colours. The concentrations of several AAs varied among the cultivars. With the exception of arginine, the concentrations of all other essential AAs on a protein basis decreased as protein levels increased. Out of 10 essential AAs including cystine, only arginine had a positive correlation (r = 0.79) with protein content. The dietary fibre contents varied between 190.7 and 223.1 g kg -1 and the values were slightly higher in the brown-seeded cultivars. The brown-seeded cultivars contained appreciable quantities of tannins, while the yellow-and green-seeded cultivars were devoid of tannins. The cultivars were almost devoid of fat and calcium but relatively high in phosphorus. Starch and dietary fibre were negatively correlated with protein content (r = -0.78 and -0.46, respectively), and accounted for the greatest difference in protein content. The TME values ranged from 11.6 to 13.3 MJ kg -1 while the TME n values ranged from 11.0 to 12.9 MJ kg -1 . The mean availabilities of AAs ranged from a high of 89.6 to a low of 75.9%, with total sulphur AAs (cystine and methionine) having the lowest value and glutamic acid having the highest value. There was a trend (P ≤ 0.05) towards lower AA bioavailability values in the brown-seeded cultivars. It can be concluded that these cultivars varied in chemical composition, metabolizable energy content and bioavailability of AAs.Key words: Field peas, composition, digestibility, chicken, poultry Igbasan, F.

Douze cultivars de pois à grain jaune, vert et brun ont été évalués sur la composition chimique et sur la digestibilité chez les volailles. L'évaluation comportait les analyses des teneurs en protéine, en acides aminés (AA), en matière grasse, en amidon, en fibres, en cendres, en calcium, en phosphore et en tanins. L'énergie métabolisable vraie, corrigée (EMV n ) ou non (EMV) en fonction de la concentration azotée et la biodisponibilité vraie des AA étaient également calculées sur des coqs adultes. On relevait parmi les cultivars un large écart de teneurs en protéine (207,5-264,0 g kg -1 ) et en amidon (385,3-436,8 g kg -1 ), lesquelles n'etaient aucunement reliées à la coloration du tégument.

“…A review by Clandinin and Robblee (1983) summarized that TME and AME n of low glucosinolate canola meal were 1.99 to 2.36 kcal/g and 1.73 to 2.17 kcal/g, respectively. A metabolizable energy value of 1.92 kcal/g (Askbrant, 1988) and TME values of 2.20 to 2.53 kcal/g (Salmon, 1984a;Askbrant, 1988;Sibbald, et al, 1990) have also been suggested for canola meal.…”

The TME, true amino acid availability (TAAA), AME, and apparent amino acid availability (AAAA) were determined in full-fat seeds, meals, oils, and meal-oil mixtures of flax and canola using Single Comb White Leghorn roosters by the force feeding and total excreta collection assay. The metabolizable energy values were corrected to zero nitrogen balance to obtain AMEn and TMEn. The AMEn and TMEn contents of canola seed (4.46 and 4.56 kcal/g) were respectively higher (P < .05) than those of flax seed (3.75 and 3.75 kcal/g). Flax meal contains contents of AMEn (2.07 kcal/g) and TMEn (2.07 kcal/g) similar to those (1.98 and 2.09 kcal/g) of canola meal. There were no differences in AMEn and TMEn values between flax oil (8.10 and 8.28 kcal/g) and canola oil (8.25 and 8.46 kcal/g). No differences were observed among AME, AMEn, TME, and TMEn values within each test ingredient except canola meal: its TME value was higher (P < .05) than its AMEn value. The TAAA values were higher for full-fat seeds than for the meals and also higher for canola seed and meal than for flax seed and meal. The AAAA values, although lower than TAAA values, followed similar patterns as TAAA values. Both AAAA and TAAA values were higher when the ingredients were fed with a basal diet than when fed alone.

“…A energia metabolizável dos alimentos pode variar com a linhagem das aves (Yaghobfar, 2001) e o método de alimentação (Askbrant, 1988) utilizados nos ensaios de metabolismo. Segundo Franchesch et al (2002), deve existir uma preocupação constante com a conveniência de se utilizar um tipo de ensaio de metabolismo específico para avaliar a digestibilidade da energia do alimento para aves.…”

RESUMO -Essa pesquisa foi desenvolvida para se avaliar o valor nutricional da soja integral submetida a diferentes processamentos. Quatro ensaios de metabolismo foram conduzidos para determinar os coeficientes de digestibilidade da matéria seca (CDMS), do extrato etéreo (CDEE) e dos aminoácidos e os valores de energia metabolizável aparente e verdadeira da soja integral desativada (SID) e extrusada (SIE) e das misturas de farelo de soja com óleo degomado de soja (FSO) ou com óleo ácido de soja (FSOA). Nos ensaios um e dois, utilizou-se a metodologia tradicional de coleta total de excretas com pintos e galos, respectivamente. A metodologia da alimentação forçada com galos adultos intactos foi utilizada no ensaio três, e com galos cecotomizados, no ensaio quatro. Os CDMS e CDEE e a energia metabolizável determinados com galos foram superiores aos determinados com pintos. Os maiores valores de CDMS, CDEE e de energia metabolizável foram obtidos para FSO, seguidos pelos da SIE e FSOA, e os menores, para a SID. O processo de extrusão proporcionou melhores resultados no aproveitamento da gordura do grão de soja e, conseqüentemente, da energia. Entretanto, a digestibilidade dos aminoácidos não foi influenciada pelos processamentos. Os diferentes processamentos conferiram à soja integral características nutricionais que se distinguiram, principalmente quanto ao valor de energia metabolizável, que também variou com a idade das aves.Palavras-chave: extrusão, galos, pintos, processamento térmico, soja desativada Effects of Processing on Full Fat Soybean Metabolizable Energy Determined by Different Methodologies and Digestibility of Amino Acids for PoultryABSTRACT -This work was conducted to evaluate the nutritional value of whole soybean submitted to different processing. Four trials were conducted to determine digestibility coefficients of dry matter (DCDM), ether extract (DCEE) and amino acids and the values of apparent and true metabolizable energy of the whole deactivated soybean processed by steam heated (WDS) and whole extruded soybean (WES) compared to a mixture of soybean meal plus soybean oil (SMO) and soybean meal plus soybean acid oil (SMAO). The trials one and two were conducted by using the total collection of excreta method with chicks and roosters, respectively. In the trials three and four, the force-feeding method with intact and cecectomized roosters, respectively, were used. The DCDM, DCEE and metabolizable energy determined by using roosters were higher than that determined with chicks. The DCDM, CDEE and metabolizable were higher for SMO, followed by WSE, SMAO and WDS. The DCMS, DCEE and metabolizable energy of WSE were higher than those of WDS. The amino acids digestibility coefficients did not differ for soybeans. The processing of whole soybeans promoted different values in the metabolizable energy of soybeans, which varied also with the bird age.
