“…This product can replace some of the standard protein and energy sources in the poultry diet. The beneficial effects of heating to destroy the antinutritional factors and improve metabolisable energy and amino acid availability values in beans, soybean, peas and canola seeds are well established (Jeunink and Cheftel 1979;Shen et al 1983;Marty and Chavez 1994;Alonso et al 2000Alonso et al , 2002Marzo et al 2002). Heat treatment, however, may produce carbohydrate-amino acid (Maillard) reactions, which result in linkages that are not hydrolyzed by digestive enzymes and thus the availability of some amino acids such as arginine, histidine, tryptophan and lysine may be reduced depending on temperature and length of exposure to heat (Cheftel 1986;Prudencio-Ferreira and Areas 1993).…”

. 2007. Nutritive value of an extruded blend of canola seed and pea (Enermax TM ) for poultry. Can. J. Anim. Sci. 87: 115-120. A study was conducted to evaluate the nutritive value of Enermax TM , which is a blend (50:50 wt/wt) of extruded full-fat canola seed and pea. Four blended samples from each of four batches were collected prior to extrusion (raw) and four samples from the same batches were collected after extrusion to give eight test samples. The canola seed in two of four batches were of good quality and in the other two were 8% bin-heated. The precision-fed adult rooster assay was used to determine the true metabolisable energy (TMEn) and true amino acid digestibility (TAAD) contents of variously treated feed samples. Both intact and cecectomized roosters were used in the assays. The average TMEn (kcal kg -1 DM) of the extruded product was 4051 ± 93 (mean ± SD; n = 16) for intact birds and 4019 ± 110 (n = 16) for cecectomized birds whereas the TMEn of the raw product was 3754 ± 136 (n = 16) in cecectomized birds. The true digestibilities of all amino acids were similar for extruded and raw product of canola seed-pea blend containing either good quality or 8% binheated canola seed (P > 0.10). These data indicate a high available energy content of the extruded product with little difference in TMEn content when measured using either intact or cecectomized roosters. It was concluded that extrusion improved the bio-available energy content of the canola seed-pea product, but not true amino acid digestibility. Further, the current results indicate that substitution of bin-heated (8%) canola seed for good quality canola seed did not adversely affect TMEn or TAAD of the extruded product. Les auteurs ont utilisé pour cela de poulets adultes entiers ou qui avaient subi l'ablation du caecum. La TMEn moyenne (kcal par kg de matière sèche) du produit extrudé s'établit à 4 051 ± 93 (moyenne ± É.-T.; n = 16) pour les sujets entiers et à 4 019 ± 110 (n = 16) pour ceux privés du caecum, contre une TMEn de 3 754 ± 136 (n = 16) pour le produit brut chez les oiseaux traités. La digestibilité réelle des acides aminés était similaire pour le produit brut et le produit extrudé, que le mélange renferme des graines de canola de bonne qualité ou 8 % de graines chauffées (P > 0,10). Ces résultats indiquent une forte teneur en énergie assimilable dans le produit extrudé, avec une faible variation de la teneur en TMEn, qu'on se serve de sujets entiers ou privés du caecum. On en conclut que l'extrusion accroît la concentration d'énergie bio-assimilable du mélange canola-pois, mais pas la digestibilité réelle des acides aminés. D'autre part, ces résultats révèlent que la substitution de graines de bonne qualité par des graines chauffées (8 %) n'a pas d'incidence néfaste sur la TMEn ni la TAAD du produit extrudé.

“…The digestibility of both crops has benefited from processing. Whole canola has shown low fat digestibility (Leeson et al 1986), which was counteracted by effective hammer-milling (Bell and Keith 1986) as well as pelleting (Shen et al 1983) in studies with broiler chickens. Field peas may have low starch digestibility (Longstaff and McNab 1987) which can be improved by heat treatments such as steampelleting (Waldroup and Smith 1989) and expansion (Armstrong 1993).…”

Whole canola/pea and whole canola/canola meal blends in diets for broiler chickens. 1. Evaluation of steam-pelleting or expansion processing Can. J. Anim. Sci. 77: [185][186][187][188][189][190]. Whole canola blended with whole peas (1:1; WCP) or canola meal (3:1; WCC) provide complementary high energy-protein supplements for poultry feeding. Both WPC and WCC blends were fed with or without processing (steam-pelleting or expansion) to broiler chicks in a 14-d feeding trial. Pelleted WCP supported higher body weight gain and feed efficiency than the untreated blend (P < 0.05). Body weight gain and feed efficiency obtained with chicks fed pelleted WCP or WCC were similar to those obtained for the expanded blends (P > 0.05), with notable exception of the expanded WCC which had a lower feeding value. With the pelleted or expanded blends, protein digestibility, N-retention, fat digestibility, and AME N were comparable or improved over the unprocessed blends, again with the exception of the expanded WCC. The processed blends had higher gelatinized starch, and lower protein solubility and myrosinase activity index. Protein solubility was very low for the expanded WCC, which is indicative of excessive heat damage. Although the expanded blends had lower glucosinolate content, this did not result in improved growth performance over the pelleted blends. It was concluded that the nutritional value of pelleted blends were at least equivalent to that of the expanded WCP and WCC for broiler chicks. [185][186][187][188][189][190]. Les graines de colza canola mélangées au pois (CEP) en proportion volumique égale ou au tourteau de canola (CEC) en proportion 3:1 constituent un riche complément énergo-protéique pour l'alimentation de la volaille. Chacun des deux mélanges a été servi, avec ou sans traitement d'agglomération à la vapeur ou d'expansion, à des poulets de chair durant un essai d'alimentation de 14 jours. Le CEP en agglomérés donnait lieu à un GMQ et à un IC meilleur que le mélange non transformé (P < 0,05). Le GMQ et la valorisation des aliments chez les poulets recevant CEP ou CEC sous forme granulés étaient semblables à ceux obtenus avec les mélanges expansés (P > 0,05), à l'exception notable de CEC expansé qui affichait une valeur alimentaire plus faible. Quel que soit le mode de présentation, les deux mélanges étaient comparables ou supérieurs aux mélanges non transformés, aux les plans de la digestibilité des protéines, de la rétention de N, de la digestibilité de la graisse et de AME N , à l'exception encore du CEC expansé. Les mélanges transformés contenaient plus d'amidon gélatinisé; leurs protéines étaient moins solubles et ils avaient un indice d'activité myrosinase plus bas. La solubilité des protéines était particulièrement basse dans le CEC expansé, signe révélateur d'une altération thermique excessive. Bien que les mélanges expansés contenaient moins de glucosinolates, la croissance des poulets n'en n'a pas pour autant été améliorée par rapport aux mélanges sous forme agglomérée. Il ressort de ces observa...
