“…The differences in the nutrient utilization between the two varieties of fullfat soybeans used in this experiment were small (P > 0.05). Previous results reported by Nesheim et al (1962), Saxena et al (1963) and Leeson et al (1987) indicate that the effects of including full-fat soybeans in the diets of broiler chickens were less for older than for younger birds. In the present study, dietary level of full-fat soybeans had little influence on performance (Table 3) or nutrient utilization (Table 4).…”

Hamilton, R. M. G. and McNiven, M. A. 2000. Replacement of soybean meal with roasted full-fat soybeans from high-protein or conventional cultivars in diets for broiler chickens. Can. J. Anim. Sci. 80: [483][484][485][486][487][488]. The effects were examined of replacing part or all of the soybean meal in the starter and finisher diets for male broiler chickens with ground, roasted, full-fat soybeans from either a high-protein (AC Proteus) or conventional (Baron) cultivar. The starter (1-21 d) and finisher (22-36 d) diets were formulated by replacing, on an isonitrogenous basis, part or all of the soybean meal in the barley-wheat-based control diets with the roasted soybeans. Digestibility of dry matter, corrected nitrogen and energy were estimated by an index method for the last 2 d of the starter and grower periods. Soybean level influenced body weight gains directly in a quadratic manner, and feed intakes or feed conversions by inversely linear relationships (P < 0.05 and P < 0.01) during the starter period. Performance during the finisher period or during the entire growth period was not influenced (P > 0.05) by dietary soybean source. Dry matter and energy digestibilities at both 21 and 35 d, and nitrogen at 35 d were affected in a quadratic manner (P < 0.05 or P < 0.01) by the soybean level of the diets, whereas, a linear relationship was present for the apparent metabolizable energy (AME) content (P < 0.001). Soybean source had no effect on nutrient utilization, except for dry matter or energy digestibility during the starter period (P < 0.01). In conclusion, the optimal performance should be obtained when the ratio of roasted full-fat soybeans to soybean meal is about 2:1 in the starter feeds for broiler chickens. . L'aliment de démarrage, servi de 1 à 21 j et l'aliment de finition de 22 à 36 j étaient formulés en remplaçant sur une base isoazotée tout ou partie du tourteau dans un régime à base d'orge et de blé par des graines de soja non torréfiées. Nous calculions la digestibilité de la matière sèche (m.s) de l'azote corrigé et de l'énergie par une méthode indicielle dans les deux derniers jours de la phase de démarrage et de celle de finition. La proportion de soja substituée se répercutait directement sur le gain de poids en fonction quadratique et sur l'ingéré ou sur l'indice de consommation en fonction linéaire inverse (P < 0,05 et 0,01) durant la phase de démarrage. La forme de présen-tation du soja n'avait pas d'effet (P > 0,05) sur les performances zootechniques, que ce soit durant la phase d'engraissement ou dans l'ensemble de la durée d'élevage. La digestibilité de la m.s. et de l'énergie à 21 et à 35 j et celle de l'azote à 35 j étaient modulées en fonction quadratique (P < 0,05 ou P < 0,01) par la proportion de soja non dégraissé dans l'aliment, tandis que la EMA (énergie métabolisable apparente) l'était en fonction linéaire (P < 0,001). La forme de présentation du soja, tourteau ou graines non déshuilées, n'avait pas d'effet sur la valorisation des nutriments, sauf celle de la m.s. et de l...

“…Though Nesheim et al, (1962) reported that RSB inhibited fat utili zation in young chicks, the results of these studies (experiment 6418) would suggest that digestibility or absorption of fat is not markedly affected in pigs as the digestibility averaged 88.7 percent for pigs fed RSB diets as compared with 90.0 percent for pigs fed SSBM diets and the difference was not significant.…”

“…Other investigators, Saxena et al, (1963b), Nitsan and Alumot (1963), Nesheim et al, (1962) and Haines and Lyman (1961), all have suggested that raw soybean meal or fractions thereof produce pancreatic enlargement in chicks and rats. One group of investigators, Singh e^ al^., (1964) showed a similar enlarged pancreas in chicks fed raw soybeans.…”
