“…In this study, cows fed the HSO diets had a lower activity of SOD and GSH-Px than fed the CON diet, which indicated that the HSO diets can reduce the antioxidant capacity and increase the oxidative stress of dairy cows. This nding is in accordance with a previous report from Pi et al [69], who suggested that diet supplementation with rubber seed oil and axseed oil had a lower activity of CSH-Px in serum than that in cotrol group, whereas the SOD activity not affected dy dietary treatment.…”

Background: The aim of this study was to investigate the effect of dietary supplementation of fine ground corn and soybean oil on ruminal fermentation, milk performance and fatty acid profile, plasma metabolites and oxidative stress parameters in lactating dairy cows. Methods: Eight primiparous Holstein cows (215±34 d days in milk, 574.6 ± 22.6 kg body weight; mean ± SD) were allocated into 2 groups (n=4/group), used in a change-over experiment with two 23-d experimental periods (16 d induction period and 7 d wash-out period). During the induction period, the cows of one group were fed with control diets (CON, 23.8% starch, 4.6% fat, and 31.4% NDF, DM basis), and the cows of the second group were fed with CON diets supplementation of 266 g/kg of fine ground corn and 46 g/kg of soybean oil (HSO, 31.4% starch, 7.8% fat, and 26.4% NDF, DM basis), and all cows were fed with the CON diets during the subsequent wash-out period. Results: The results shown that the cows fed the HSO diets had a lower ruminal molar ratio of acetate (P = 0.02), and a numerically lower ruminal pH (P = 0.13) and acetate : propionate ratio (P = 0.13) than that in the cows fed the CON diets. Cows fed the HSO dites had a lower (P < 0.05) dry matter intake (DMI), milk yield, milk fat percentage, the yield of milk fat, protein and solid of non-fat (SNF), and a higher (P<0.05) percentage of milk protein, lactose and SNF than that in the cows fed with CON diets. Cows fed the HSO diets had a lower (P < 0.05) concentrations [g/100 g total FA] of C8:0, C10:0, C11:0, C12:0, C14:0, C15:0, C16:0, C17:0, C18:0, fatty acids (FA) <C16, sum of C16:0 and C16:1, total saturates FA, and medium chain FA, and a greater (P < 0.05) milk concentrations of C14:1, C16:1, C18:1n9t, C18:2n6t, C18:2n6c, C18:3n3, FA > C16, total unsaturated FA, total mono-unsaturated FA, total poly-unsaturated FA, Δ9-desaturase index, than that in the cows fed the CON diet. Compared with the cows fed the CON diet, the concentrations of plasma non-esterified fatty acids (NEFA), aspartate aminotransferase (AST), malondialdehyde (MDA) increased (P < 0.01), whereas the concentrations of theβ-hydroxybutyrate (BHBA), urea nitrogen (BUN), alanine aminotransferase (ALT), albumin (ALB), total antioxidant capacity (T-AOC), the ratio of ALB to GLB, the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) decreased (P < 0.05) in cows fed the HSO diets. Conclusions: Our results indicate that HSO diets can impact on the ruminal fermentation pattern, reduce the DMI, milk fat content, depress the de novo synthesis of lipid in mammary gland, disturb plasma parameters, enhance the oxidative stress in dairy cows. Meanwhile, we also found the the subacute rumen acidosis (SARA) and milk fat depression (MFD) can occur at the same time or one after the other, when dairy cows fed with HSO diets.

“…The n-3 PUFA content in milk can be influenced by the composition of the diet, and therefore flaxseed is the main source of n-3 PUFAs in diets used for dairy cows. Previous studies have shown that flaxseed supplementation can increase the concentration of n-3 PUFAs, particularly ALA, in milk [ 6 , 7 , 8 , 9 ] and plasma [ 10 ]. Flaxseed is rich in ALA; 18% of the total seed (dry matter [DM] basis) or 53–56% of the total fatty acid content in flaxseed is composed of ALA [ 11 , 12 ].…”

The objective of this study was to determine the effect of whole flaxseed and ground flaxseed supplementation on the composition of fatty acids in plasma and milk, particularly the content of omega-3 polyunsaturated fatty acids (n-3 PUFAs). Thirty Holstein dairy cows were randomly assigned to three treatment groups. Cows were fed a total mixed ration without flaxseed (CK), 1500 g of whole flaxseed (WF), and 1500 g of ground flaxseed (GF) supplementation. There were no differences observed in dry matter intake, milk yield, energy-corrected milk, and 4% fat-corrected milk (p > 0.05). Compared with the CK group, the contents of α-linolenic acid (ALA), eicosatrienoic acid, and eicosapentaenoic acid increased in the plasma and milk WF and GF groups, and the content of docosahexaenoic acid and total n-3 PUFA was higher in GF than the other groups (p < 0.001). The ALA yield increased to 232% and 360% in WF and GF, respectively, compared to the CK group. Compared with the WF group, GF supplementation resulted in an increased milk ALA/ALA intake ratio (p < 0.001). Flaxseed supplementation increased the activity of GSH-Px and decreased the concentration of MDA in milk (p < 0.001). Plasma parameters did not differ among the treatments (p > 0.05). This result indicated that compared with the WF group, GF supplementation in the diet showed higher efficiency in increasing the total n-3 PUFA levels and the milk ALA/ALA intake ratio, and decreased the ratio of n-6 PUFAs to n-3 PUFAs in milk.

“…In this study, addition of 3.5% or 4.5% rubber seed oil to the diet did not affect the production performance of laying hens, except for a declined abdominal fat percentage. In dairy cows, supplement of 40 g/kg rubber seed oil or flaxseed oil increased the functional fatty acids such as ALA, vaccenic acid and conjugated linoleic acid and decreased SFAs in milk fat, but with phospholipids, growth hormone, insulin and beta-hydroxybutyric acid in blood unchanged [ 13 ], and even enhanced their immune function [ 14 ]. Moreover, consumption of refined rubber seed oil proved to be safe and hypolipidemic in rhesus monkeys [ 15 ] and human beings [ 16 ].…”

Objective: This study aims to evaluate the effects of dietary supplement of rubber seed oil on production performance, egg quality, and yolk fatty acid composition in laying hens during a 16-week feeding trial period.Methods: Forty-eight 25-week-old laying hens of Hy-Line Brown were randomly divided into three groups. Each group comprised four replicates and each replicate had four birds. Rubber seed oil was incorporated into a corn-soybean meal basal diet by 3.5% (group I), 4.5% (group II), or 0 (control group) and equivalent nutrition was supplied for the test groups and the control group. The performance related values were determined using standard or well established methods.Results: No significant difference was found in the production performance, the egg quality, the composition of saturated fatty acids, and the content of cholesterol and monounsaturated fatty acids in the yolk within the three groups. Interestingly, both test groups achieved a significantly higher content of linoleic acid, α-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid and a significantly lower content of arachidonic acid (p<0.05) compared with the control group. With the increased level of dietary rubber seed oil, there was an increasing trend in the content of n-6 polyunsaturated fatty acids (PUFA), n-3 PUFA and total PUFA, but a declining trend in the n-6/n-3 ratio.Conclusion: These results demonstrate that the rubber seed oil supplemented diet effectively improved the total PUFA content in eggs without impairing the layers’ production performance and the egg quality.
