Abstract

Two experiments were conducted to determine the nitrogen-corrected apparent metabolizable energy (AMEn) of differently processed meals from Juncea (Brassica juncea), yellow and black seeded canola (Brassica napus), with or without supplementation of multi-carbohydrase enzymes (Enz) in diets for broiler chickens. The first experiment was a 3 × 2 × 2 factorial arrangement with the main factors being seed type (yellow [Yellow] or black [B1] canola seeds and Juncea seeds), processed at two temperatures (high temperature desolventized-toasted [HTDT] at 95°C or low temperature desolventized-toasted [LTDT] at 57°C), with or without Enz. In Exp. 1, a total of 384 one-day-old male broiler chicks were randomly assigned to 64 battery cages, with 6 birds/cage. The second experiment was a 2 × 2 × 2 factorial arrangement with the main factors being seed type (Yellow or black [B2]), seed source (Scott, Saskatchewan or Truro, Nova Scotia) and Enz (with or without) supplementation. A total of 264 one-day-old male broiler chicks were randomly assigned to 44 battery cages, with 6 birds per cage. In Exp. 1 and 2, all birds were fed a common starter diet from 1 to 14 days of age. From d 15 to 21, the birds were fed one of the test treatments, a bas...Continue Reading
