A visualization of testing apparatus was developed to measure property of oilseeds relevant to physical mechanics during mechanical pressing for oil extraction. Stress-strain relationships were measured for extruded peanut, soybean, sesame and linseed compressed at thirteen pressures under uniaxial cold pressing. The prediction model of the stress-strain relationship was developed based on BP n...

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...

This study evaluated the effects of a dietary mixture based on extruded linseed and pea (ELP; 20:80 w/w) probiotics (L. acidophilus) performance, biochemical responses, breast muscle fatty acids (FA) profile, lipid indices in broiler chickens. A total 480 one-day-old Ross 308 broilers were assigned into four groups 2 × factorial arrangement with two levels ELP (0% 30%) at expense soybean meal, ...

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...

There is evidence that n-3 fatty acids (FA), especially EPA and DHA, are beneficial for human health. This thesis examined factors influencing FA composition in common carp flesh, sought to develop a procedure for long-term sustainable culture of common carp with improved muscle lipid quality (omega 3 carp) and studied the health benefits of eating such carp in the secondary prevention of cardi...

An experiment was conducted to compare the effect of corn-soybean meal finisher (29-42d) diets containing flaxseeds (rolled or extruded) on pellet quality, performance, n-3 fatty acids (FA) and oxidative stability of meat in broiler chickens. Seven pelleted diets were provided in a 3×2 factorial arrangement with three flaxseed levels (5, 10, and 15%) and two processing methods (rolled or extrud...

eggs l A preliminary study showed that maximum enrichment of egg lipid with omega-3 polyunsaturated fatty acids (LCPUFA) had not occurred after about 5 days on dietary oil regimens. When cod liver oil, canola oil or linseed oil was added at 7% to layer diets for 12 weeks, production parameters were usually better than on the commercial layer diet; e g g w e i g h t was normally higher on the oi...

The effect of cooking on protein oxidation was investigated in M. Longissimus thoracis of eight Normand cows fed during a 100 days finishing period with two different diets: a conventional diet (concentrate/straw based diet) and a diet rich in n-3 polyunsaturated fatty acids (PUFAs), obtained by addition to the conventional diet of a mixture of extruded linseed and extruded rapeseed. After 11 d...

The objective of this study was to determine the effect of a linseed supplement on follicle growth, progesterone concentrations and milk and plasma fatty acids in dairy cows post partum. Sixteen Holstein cows were given a basal total mixed diet plus one of two supplements: control (C; extruded soybeans; n = 8) or linseed (L; extruded linseeds; n = 8). One month after calving oestrous cycles wer...

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...
