“…The TAAA values reported here for most of the amino acids were lower than, but within 1 to 7% of, those values obtained for canola meal Salmon, 1984a) and 4 to 8% of those values reported for canola seed . Several factors may account for such small differences.…”

“…indicated that TAAA values, except tyrosine and cystine, ranged from 82 to 95% and 86 to 96% for canola meal and seed. Salmon (1984a) reported TAAA values of 83 to 97% for canola meal except for cystine. The availability of most amino acids in canola seeds and meals was higher than that of flax seed and meal (Barbour and Sim, 1991).…”

“…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.

Supplementing a 15% protein diet for chickens, with all the protein coming from canola meal, with essential amino acids (EAA) to bring diet levels up to those recommended by NRC, failed to improve weight gain over that of an unsupplemented canola meal diet. While feed:gain ratio of the EAA-supplemented diet was improved, performance was markedly inferior to that of a 20% protein corn-soybean meal diet. Supplementing the canola meal basal diet with corn oil, lysine, or lysine plus arginine resulted in significant responses; however, performance was again far below that of the corn-soybean meal positive control diet. Supplementing the canola meal basal with EAA to bring levels up to close to the corn-soybean meal control diet resulted in performance which was superior to that obtained in the experiments in which EAA were supplemented to NRC requirement levels. However, performance was still markedly inferior to the corn-soybean meal control diet. A point of interest was the failure to demonstrate a need for methionine supplementation of the canola meal diet, even though by calculations it should have been deficient in this amino acid. A marked improvement in performance occurred when the level of methionine supplementation was reduced from 0.28 to 0.1% for the canola meal diet, supplemented with lysine, arginine and tryptophan. This clearly demonstrates that excess methionine or sulphur supplementation can markedly alter the performance of canola meal diets and may be one of the major reasons why EAA supplementation of semipurified diets that contain canola meal has failed to result in marked improvements in performance. Key words: Canola meal, amino acid supplementation, chickens
