Feeding dairy cows a ration containing whole flax seeds (linseed), flax (linseed) oil or milled, extruded or micronized linseed has five beneficial effects on the fat profile of cow’s milk: (1) increasing the content of alpha-linolenic acid (ALA); (2) increasing the content of conjugated linoleic acid (CLA); (3) decreasing the omega-6/omega-3 ratio; (4) decreasing the overall saturated fat cont...

Replacing dietary grass silage (GS) with maize silage (MS) and dietary fat supplements may reduce milk concentration of specific saturated fatty acids (SFA) and can reduce methane production by dairy cows. The present study investigated the effect of feeding an extruded linseed supplement on milk fatty acid (FA) composition and methane production of lactating dairy cows, and whether basal forag...

the aim of this study was to evaluate the effect of glycogenic diets supplemented with different poly unsaturated fatty acids on reproductive performance of iran black ewes in two different managing programs. ewes were allocated in two different groups; group a (n = 75) and group b (n = 25). ewes from group a were stopped from suckling followed by introducing to the rams on days 80 and 90, resp...

the present study was conducted to evaluate the effects of extruded linseed on milk production,dry matter intake and reproduction performance of 300 holstein lactating cows (35±15 days in milk;41±9/8 kg/day of milk production). cows were placed in a completely randomized design of 2treatments (concentrate containing 7 percent of extruded linseed vs. control), (150 cows pertreatment). cows were ...

Twenty-four barrows (78.1 +/- 1.7 kg of initial BW) were fed a control diet (2.5% sunflower oil) or an experimental diet containing 5% whole extruded linseed. Both diets were supplemented with 170 mg of vitamin E/kg of feed. At slaughter (160 +/- 9.2 kg of BW), 6 hams were collected per group and delivered to Stazione Sperimentale per l'Industria delle Conserve Alimentari of Parma for seasoning...

this study was conducted to evaluate the effects of extruded linseed on milk production, dry matter intake and reproduction performance of 300 holstein lactating cows (35±15 days in milk; 41±9/8 kg/day of milk production). cows were utilized in a completely randomized experimental design, comprised of: 2 treatments (concentrate containing 7 percent extruded linseed vs control) with a number of ...

The qualitative characteristics, lipids and chemical composition of the meat of 35 Nellore young bulls were analyzed. These bulls had an average slaughter weight and fat thickness of 532.17±30.2 kg, and 7.00 mm, respectively. Significant differences were found only in the meat's water holding capacity (WHC), which was higher for animals fed with fresh linseed oil. More conjugated linoleic acid ...

one-hundred-sixty-eight 28-wk-old hy-line layers (w-36) were used to evaluate the effect of different levels of linseed (ls) and safflower seed (ss) on antibody titter, blood and yolk cholesterol, yolk fatty acid content and the ratio of omega-6/ omega-3. hens were randomly assaigned in a compeletly randomised design each 3 replicates of 8 hens. they were fed diets contained 0, 4, 7 and 10% ls ...

The Western diet is characterized by a high intake of SFA relative to PUFA, and the consumption of n-3 PUFA is decreased relative to n-6 PUFA. Therefore, there has been much interest in recent years in ways to manipulate the fatty acid composition of meat. The objective of this work was to determine the effects of dietary extruded linseed, an n-3 PUFA source, on growth performance, carcass comp...

Three diets for cows were used to evaluate the effect of extruded linseed (EL) or extruded linseed plus alpha-tocopherol (ELVE) supplementation of a maize silage diet (CO) on the odor-active compounds of Saint-Nectaire cheese. Cheese odor and flavor profiles were studied by sensory analysis. The volatile compounds were extracted by purge and trap and separated by gas chromatography. The odor co...
