“…This process limits the level of UFA in milk and dairy products. Some previous studies also showed that feeding high amounts of oil sources in the ruminant diets could cause adverse effects on feed intake and nutrient digestion and retention (Bernard et al ; Bhatt et al ), resulting in decreased animal performance (Gómez‐Cortés et al ), milk yield and milk fat yield (Hutchinson et al ; Lunsin et al ). In most situations, total dietary lipid in ruminant diets should not exceed 6‐7% of dietary dry matter (DM) (NRC ).…”

Thirty-six Holstein-Friesian crossbred lactating dairy cows were used to determine the effects of linseed oil supplementation on performance and milk fatty acid (FA) profile. Three treatments were as follows: basal diet (56:44 Roughage:concentrate [R:C] ratio, dry matter basis) supplemented with 500 g of palm oil as control (PO), 500 g mixture (1:1, w/w) of palm oil and linseed oil (POLSO) and 500 g of linseed oil (LSO). The LSO supplementation had no effects on total dry matter intake (DMI), milk yield and milk composition. Compared to control cows, cows supplemented with LSO increased milk concentrations of cis-9,trans-11 conjugated linoleic acid (CLA) and n-3 FA (P < 0.05), particularly C18:3n-3, C20:5n-3 and C22:6n-3. Feeding LSO reduced concentrations of milk short- and medium-chain saturated fatty acids (P < 0.05) while it increased concentration of milk unsaturated fatty acids (P < 0.05). Milk proportions of n-3 FA increased, whereas n-6/n-3 ratio decreased in the LSO as compared with the control (P < 0.05). In conclusion, supplementing dairy cows' diet based on corn silage with LSO at 500 g/day could improve the nutritional value of milk with potential health-beneficial FA without detrimental effect on milk composition or cow's performance.

This study investigated the effect of fumarate (FUM) and rice bran (RB), alone and together, on in vitro rumen fermentation, methanogenesis and methanogens. In vitro incubation was performed with six media that were either unsupplemented (control) or supplemented with 10% RB, 5 mmol/L FUM, 10% RB + 5 mmol/L FUM, 10 mmol/L FUM, or 10% RB + 10 mmol/L FUM. Methane (CH4 ) production, dry matter digestibility, CH4 per digested dry matter, total short-chain fatty acid (SCFA) production, proportion of SCFA, acetate : proprionate ratio, production of NH3 -N, and population density of rumen microbes were determined. Supplementation with 10% RB + 10 mmol/L FUM yielded a 36% decrease in CH4 production compared to the control. Supplementation of FUM, in the presence or absence of RB, provided increases in total SCFA production and propionate proportion up to 61% and 31%, respectively. Total bacteria, methanogens and protozoa populations were significantly (P < 0.05) decreased with the 10% RB + 10 mmol/L FUM supplementation. The effect of anti-methanogenesis of FUM was enhanced by the addition of RB. Notably, the CH4 production attenuation was achieved by 10% RB + 10 mmol/L FUM without reduction of digestibility or of ruminal fermentation.

“…() reported that adding 3% linseed oil can decrease the ruminal NDF digestion. Adding 6% oil can reduce the NDF digestibility, but the lower levels have no effect on the NDF digestion (Lunsin et al., ). The difference between studies might be partially due to composition of the basal diet (i.e.…”

SummaryThis experiment was carried out to examine the effect of grapeseed oil (GSO) on performance, rumen fermentation, antioxidant status and subcutaneous adipose fatty acid (FA) profile in lambs. Eighteen Baluchi lambs, 196 AE 14 days of age and 39.8 AE 1.7 kg body weight, were randomly assigned to three experimental diets: (i) diet without GSO (control), (ii) diet containing 2% of GSO (GSO2) and (iii) diet containing 4% of GSO (GSO4) for 42 days. Results showed that the experimental diets had no significant effect on dry matter intake and performance (p > 0.05). The supplemented diets with GSO had no effect on pH and NH 3 -N of rumen fluid (p > 0.05), but GSO4 increased (p = 0.003) the concentration of propionic acid and reduced (p = 0.002) the concentration of acetate acid compared to the control. Inclusion 4% of GSO to the diet increased total antioxidant activity and decreased malondialdehyde in serum and muscle (p < 0.001). The level of blood glutathione peroxidase in diets containing GSO was higher than control diet (p = 0.02), but diets had no effect on superoxide dismutase in blood and muscle tissues (p > 0.05). The concentration of vaccenic acid, rumenic acid and linoleic acid and thus polyunsaturated fatty acid in subcutaneous fat was affected by experimental diets (p < 0.001), as control had the lowest amount of these FAs and GSO4 had the highest amount of them. Therefore, it can be concluded that the use of GSO up to 4% improves the antioxidant status and adipose fatty acid profile in lambs without effects on performance.
