Thirty lactating dairy cows were used in a 3 × 3 Latin-square design to investigate the effects of a raw or extruded blend of linseed and wheat bran (70:30) on plasma and milk fatty-acids (FA). Linseed diets, containing 16.6% linseed blend on a dry-matter basis, decreased milk yield and protein percentage. They decreased the proportions of FA with less than 18 carbons in plasma and milk and res...

In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% α-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed gro...

Feeding beef cattle a ration containing whole flax seeds (linseeds), flax (linseed) oil, rolled linseed or milled linseed increases the alpha-linolenic acid (ALA) and conjugated linoleic acid (CLA) content and decreases the omega-6/ omega-3 ratio, but has little effect on the saturated fat content of beef. Adding linseed to feedlot diets has been shown to increase the internal fat of heifers an...

A field experiment was conducted during 2007-08 at Student Instructional Farm, Narendra Deva University of Agriculture &Technology, Kumarganj, Faizabad (U.P.), India to study the influence of different levels of sulphur and varieties of oil quality and fatty acid composition of linseed. Results revealed that significantly highest oil content (36.65%) was obtained in variety Type-397 as compared...

Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...

Four multiparous Holstein cows were used in a 4 x 4 Latin square experiment to study the effects of fat sources rich in omega-3 fatty acids on milk production and composition, follicular development, and prostaglandin secretion. All cows were fed a total mixed diet containing 60% grass silage and 40% concentrate. The four treatments were concentrates based either on Megalac, formaldehyde-treate...

This experiment studied the effect of 3 forms of presentation of linseed fatty acids (FA) on methane output using the sulfur hexafluoride tracer technique, total tract digestibility, and performance of dairy cows. Eight multiparous lactating Holstein cows (initial milk yield 23.4 +/- 2.2 kg/d) were assigned to 4 dietary treatments in a replicated 4 x 4 Latin square design: a control diet (C) co...
