Rapeseed 'f |^ and Crambe: Developing Useful Products From Oils That Are High in Erucic Acid
The use of rapeseed oil dates back to antiquity. Ancient (2000 to 1500 B.C.) writing from Greece, Rome, India, and China refer specifically to oilseed rape, its medicinal value, and its use as by Joseph Roetheli, Office of Agricultural Materials, CSRS, USDA, Washington, DC; Kenneth Carlson, Research Chemist, National Center for Agricultural Utilization Research, ARS, USDA, Peoria, IL; John Gard...
متن کاملStudies on the characterization and distribution of fatty acids and minor components of high-erucic acid mustard oil and low-erucic acid rapeseed oil
The aim of this work was to compare the positional fatty acid composition, sterols, tocopherols and oxidative stability of mustard oil (MO) and rapeseed oil (RSO). The MO contained higher levels of erucic acid (42.8%) and linolenic acid (18.2%), compared with RSO (0.4 and 8.6%) whereas the RSO contained higher levels of oleic acid (62.2%) and linoleic acid (19.5%), than that of MO (17.4 and 15....
متن کاملAmino Acid Recommendations for laying hens
During recent decades productivity of laying hens increased substantially (Elliot, 2008). Not only egg number, egg mass, and feed conversion has increased but also persistency of lay has improved. As such, this must have implications on the optimal amino acid nutrition of current laying hen strains. Simply stated, increasing egg mass output per hen means an increased amino acid output which has...
متن کاملEnvironmental and Induced Mutations Influences on Oil Content, Oleic Acid and Erucic Acid in Rapeseed
A comparative study was conducted to see the mutational analysis for monounsaturated fatty acids in rapeseed (Brassica napus L.) mutant populations. By using gamma irradiation, a range of variability generated for oil content and fatty acid composition in rapeseed seeds. The induced genetic variability was analyzed for two consecutive years in two contrasting environments at elevations of 510 a...
متن کاملAppraisal of Hematological Indices and Humoral Immunity in Commercial Laying Hens Fed Rations Consisting Cottonseed Meal and Sodium Bentonite
The objective of this study was to evaluate the effects of cottonseed meal (CSM) treated with sodium bentonite (SB) on certain blood components and immune response of laying hens. A 3 × 3 factorial arrangement with 3 levels of SB (0, 10, and 20 g/kg of diet) and 3 levels of CSM (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. Nine mash diets were fed to ...
