Rapeseed and rapeseed meal as components in diets of laying hens
Archiv für Tierernaehrung, 1996In an experiment with 405 Hisex white hens rations with 5-20% low glucosinolate rapeseed (RS) or rapeseed meal (RSM) of 00 quality were used. Feed intake, egg production, individual egg weight and live weight gain were reduced in hens fed 5-20% RS and 10-20% RSM.

Nutritive Value of Rapeseed Meals and Rapeseed Protein Isolates
Annals of Nutrition and Metabolism, 1975Defatted meals of two new varieties of rapeseed, <i>Brassica napus, </i>Erglu and Lesira, and protein isolates prepared therefrom, were fed to chicks that had been depleted of their embryonic protein reserve. First, the animals were fed at a 12 % protein level, half of it from rapeseed meal, or a rapeseed protein isolate and, subsequently ...

Antioxidant capacity of rapeseed meal and rapeseed oils enriched with meal extract
European Journal of Lipid Science and Technology, 2010AbstractResponse surface methodology (RSM) was used to evaluate the quantitative effects of two independent variables: solvent polarity and temperature of the extraction process on the antioxidant capacity (AC) and total phenolics content (TPC) in meal rapeseed extracts. The mean AC and TPC results for meal ranged between 1181–9974 µmol TE/100 g and 73.

Composition of the aqueous extracts of rapeseed meals
Journal of the Science of Food and Agriculture, 1972AbstractAqueous extracts of rapeseed meals were separated into four fractions by Sephadex (G25) column chromatography. Fraction I was found to be rich in protein as judged by nitrogen and amino‐acid content and u.v. absorbance at 280 nm. Fraction II contained glucosinolates and peptide‐like materials.

Cyano Compounds and Goitrin in Rapeseed Meal
Canadian Journal of Physiology and Pharmacology, 1972Raw rapeseed meals of Brassica campestris and cultivar Bronowski were analyzed for cyano compounds and goitrin following autolysis at 37 °C. Urine excreted from 4 to 36 h by rats dosed with the raw or heated meals (dry heat for 15 min at 110 °C) was also examined for these compounds. Unsaturated nitrile level in raw B.

Rapeseed meal and egg taint: Treatment of rapeseed meal to reduce tainting potential
British Poultry Science, 19791. Treatment of rapeseed meal with calcium hydroxide suspension decreased the sinapine content by up to 90%. Smaller decreases were obtained by autolysis, steaming and treatment with ammonia. 2. When this treated meal was fed to susceptible ("tainting") hens the concentration of trimethylamine in the eggs was decreased to much less than that required ...

Thiocyanate Ion Formation in Rapeseed Meals
Canadian Journal of Biochemistry, 1975Meal prepared from unheated rapeseed (Brassica napus cv. Zephyr) showed the presence of thiocyanate ion, while meal from heated seed of the same cultivar did not show detectable amounts. Unheated seed meal on autolysis, and heated seed meal on incubation with thioglucosidase, yielded increased amounts of thiocyanate ion.

Anaerobic treatment of rapeseed meal
Chemical Papers, 2013AbstractRapeseed meal is a solid by-product obtained from rapeseed after oil extraction. This contribution summarises experiences from batch experiments as well as the long-term processing of this substrate in a laboratory stirred anaerobic reactor (continuous stirred-tank reactor).

British Poultry Science, 1975
1. Certain rapeseed meals in the diet of hens laying brown eggs result in the production, from some birds, of eggs which have a “ fishy ” or “ crabby ” odour because of the presence of trimethylamine. 2. Such susceptible birds have been used to demonstrate that the activity can be extracted from rapeseed meal with appropriate solvents.

The tannin content of rapeseed meals
British Poultry Science, 19761. The presence of varying amounts of sinapine, a hydroxylated cinnamic acid derivative, in rapeseed meals has been shown to interfere with the usual methods of tannin estimation. 2. When correction was made for such sinapine contribution the corrected tannin levels were from 18 to 45% lower than those previously reported.
