The Effects of Canola (Brassica napus) and Juncea (Brassica juncea) Meals in Diets on Broilers and Turkeys

Abstract

Canola and juncea meals can be used in poultry diets instead of soybean meal. The meals were fed to broilers and turkeys in digestibility trials to measure the apparent metabolizable energy (AMEn). Throughout growth trials, canola and juncea meals were fed at four levels (0, 10, 20 and 30 %) with and without a dietary enzyme cocktail (DEC). This study investigated higher inclusion levels than previously recommended for use in broilers diets. The carcass compositions, fatty acid analysis and liver parameters were measured to investigate the effects of diets on birds. The AMEn of the meals were used in formulating broiler and turkey diets. Growth trials found positive effects of DEC on performance, allowed higher inclusion levels of the meals. No negative effects of diets were observed for liver parameters and carcass compositions. The fatty acid profiles of carcass tissues were improved by increasing levels of canola oil in diets.
