Enzymatic hydrolysis of rapeseed meal carbohydrates was performed to increase the protein content. Rapeseed meal was first screened and further defatted. Only particles between 0.250 and 0.707 mm in size were used, and the optimum solid/liquid ratio was found to be 10% (w/v). Commercially available carbohydrase enzyme mixtures, Viscozyme ® L, Pectinex ® Ultra SP-L, and Celluclast ® 1.5 L, were ...

The standardized ileal digestibility (SID) of CP and AA was evaluated in soybean (Glycine max) meal, sunflower (Helianthus annuus) meal, rapeseed cake, and field pea (Pisum sativum) using 10 pigs and in lupine (Lupinus angustifolius) using 7 pigs. Pigs were fitted with either a T-cannula or a steered ileocecal valve-cannula. Diets contained 170 to 186 g CP/kg DM. Endogenous losses of CP and AA ...

Rapeseed-mustard oil is an essential dietary component, in India. The modification of rapeseed- mustard for fatty acid composition of seed oil to develop new genotypes having alternative oil and meal characteristics has been an important objective in quality breeding. Moreover, Breeding efforts in India are in progress to develop double low varieties to meet the internationally acceptable stand...

This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...

The use of transgenic crops as feeds for ruminant animals has prompted study of the possible uptake of transgene fragments by ruminal micro-organisms and/or intestinal absorption of fragments surviving passage through the rumen. The persistence in buffered ruminal contents of seven different recombinant DNA fragments from GM rapeseed expressing the 5-enolpyruvylshikimate-3-phosphate synthase (E...

Several oilseed and legume protein products were fed to rats as the sole source of dietary protein, and in blends with cereals for the determination of protein efficiency ratio (PER) and biological availability of amino acids. In addition oilseed protein isolates were fed to mice for the determination of PER. Results of the mouse study revealed that the adjusted PER (casein = 100)for Target rap...

Feed ingredients of plant origin are commonly used in swine diets. However, the major components of plant cell walls, non-starch polysaccharides (NSPs), reduce nutrient digestibility. To improve the efficiency of feed utilization, exogenous enzyme products that degrade NSPs have been widely used in commercial animal feeds. Nonetheless, the effects of exogenous enzyme addition to swine diets on ...

The present study was aimed at determining rumen phosphorus availability of some feedstuffs assessed with the nylon bag technique: forage (alfalfa), cereals (control-C wheat, formaldehyde treated-FT wheat, barley, corn), cereal by-products (wheat bran, wheat distillers, corn distillers) and meals (C and FT soya bean meals, rapeseed meals and sunflower meals). Rumen phosphorus availability was n...

An experiment was conducted to deter­ mine apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) by grow­ ing pigs of P in canola meal, 00­rapeseed meal, and 00­rapeseed expellers. Canola meal and 00­rapeseed meal are the coproducts produced after the residual oil has been solvent extracted from the prepressed canola seeds and 00­rapeseeds, respectively, wh...
