“…The reduced growth obtained when birds were fed the SBM control diet (Table 3) agrees with the results of Irish and Balnave (1993a), but contrasts with those of others (Waldroup and Cotton 1974;Leeson et al 1987;Chohan et al 1993). Irish and Balnave (1993a) found that growth of broiler chickens was consistently lower in a number of trials when SBM was the sole source of supplemental protein in sorghum-wheat based diets.…”

“…Irish and Balnave (1993a) found that growth of broiler chickens was consistently lower in a number of trials when SBM was the sole source of supplemental protein in sorghum-wheat based diets. Further research indicated that the water-soluble xylose content of the SBM influenced the growth of the broilers and that multi-enzyme preparations designed to act on the non-starch polysaccharide fraction of the meals did not improve growth (Irish and Balnave 1993b).…”

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...

“…However, broiler performance and nutrient retention differed among diets and in general were higher for the HP-SBM than for the R-SBM diets, suggesting that the availability of the nutrients (AA and AME n ) contained in the 2 sources of SBM was different. These results support the data of Irish and Balnave (1993) and Dudley-Cash (1997), who indicated that the nutritive value of the SBM used in commercial poultry diets was very variable. The reduced ADG and impaired F:G observed in broilers fed the R-SBM as compared with broilers fed the HP-SBM were consistent with the higher TIA of the R-SBM.…”

Influence of source of soybean meal and lysine content of the diet on performance and total tract apparent retention of nutrients in broilers from 1 to 36 days of age

The influence of soybean meal (SBM) source and total Lys content of the diet on performance and total tract apparent retention of nutrients was evaluated in broilers from 1 to 36 d of age. There were 6 treatments arranged factorially with 2 sources of SBM [regular SBM with 46.3% CP (R-SBM) and high-protein SBM with 48.6% CP (HP-SBM)] and 3 Lys:AME(n) ratios (Lys:ME; 380, 415, and 450 mg of total Lys:1,000 kcal of AME(n) from 1 to 21 d; and 312, 338, and 364 mg of total Lys:1,000 kcal of AME(n) from 22 to 36 d of age). From 1 to 36 d of age, broilers fed the HP-SBM diets had higher ADG and better feed:gain ratio (F:G) than broilers fed the R-SBM diets (P < or = 0.001). Both ADG and F:G improved (P < or = 0.05) with increases in the Lys:ME ratio. From 1 to 21 d of age, ADG and F:G (P < or = 0.001) were improved when the Lys:ME ratio increased and the benefits were more pronounced with the diets based on R-SBM. From 22 to 36 d of age, increasing the Lys:ME ratio from 312 to 338 increased ADG (P < or = 0.05) and F:G (P < or = 0.01), but no further improvements were observed when the ratio was increased to 364. The total tract apparent retention of DM and gross energy of the diets were higher (P < or = 0.05) for the HP-SBM than for the R-SBM diets. An increase in the Lys:ME ratio reduced organic matter and N retention (P < or = 0.05). The improvements in growth performance and nutrient retention observed in broilers fed the HP-SBM diets with respect to those fed the R-SBM are consistent with a better availability of nutrients of the high-protein meal. In addition, the results indicate that Lys requirements of broilers are at least, 30, 20, and 8% higher from 1 to 10, 10 to 21, and 21 to 36 d of age, respectively, than current NRC recommendations.

“…High levels of histamine in feed can cause gizzard erosion in chickens, which in turn influence on the performance of broiler chicks [9]. It was also reported that broiler chicks fed diets containing soybean meal as the sole dietary protein concentrate consistently showed poor growth in a number of feeding trials [10]. On the contrary, Arafa et al [11] compared the effect of feeding diets containing allvegetable protein versus mixture of vegetable and animal protein sources on the performance and carcass characteristics of broiler chicks.…”

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.
