Abstract
The nutritive value of meals derived from black- and yellow-seeded Brassica napus and canola-quality Brassica juncea was determined with broiler chickens and young turkeys. A higher apparent ileal digestibility of total amino acids was observed in chickens fed diet containing yellow-seeded B. napus than in those fed conventional black-seeded B. napus or canola-quality B. juncea (88.8 vs 83.4 and 84.2%, P < 0.05). Metabolizable energy (AME(n)) contents for yellow- and black-seeded B. napus and B. juncea as determined with broiler chickens were 2190, 1904, and 1736 kcal/kg DM, respectively. In the turkey assay, the AME(n) values for yellow- and black-seeded B. napus and B. juncea canola averaged 2166, 2007, and 1877 kcal/kg DM, respectively. Multicarbohydrase enzyme addition to broiler chicken diets increased energy utilization (from 1943 to 2249 kcal/kg DM, on average), with the most pronounced effect observed for B. juncea canola (from 1736 to 2356 kcal/kg DM).
