Enteric and fecal methane emissions from dairy cows fed grass or corn silage diets supplemented with rapeseed oil,

ABSTRACT: Methane emissions from dairy cows fed grass or corn silage diets supplemented with rapeseed oil were evaluated. Enteric methane emissions decreased on adding rapeseed oil to the diet, but methane emissions from feces of dairy cows fed diets supplemented with rapeseed oil did not differ. Thus no trade-offs were observed between enteric and fecal methane emissions due to forage type or addition of rapeseed oil to diets fed to Swedish dairy cows.

Alteration of gene expression in mammary gland tissue of dairy cows in response to dietary unsaturated fatty acids

Project description:The aim of this study was to determine the effects of unprotected dietary unsaturated fatty acids (UFA) from different plant oils on gene expression in the mammary gland of grazing dairy cows. Milk composition and gene expression in the mammary gland tissue were evaluated in grazing dairy cows supplemented with different unsaturated fatty acids (UFA). The UFA supplementation improves the health and nutrition quality aspects of dairy milk, but also affects the gene networks expression signature associated with cellular growth and proliferation, cell-death, signalling, nutrient metabolism, and immune response, and in turn, the mammary gland integrity and health. A total of 28 Holstein-Friesian dairy cows in mid-lactation were blocked according to parity (2.4 ± 0.63 years), days in milk (DIM; 153 ± 32.8 days), milk yield (25.7 ± 3.08 kg/d) and fat content (4.3 ± 0.12%). Cows were then randomly assigned to four UFA-sources based on rapeseed, soybean, linseed or a mixture of the three oils for 23 days (Period I) after which, all 28 cows were switched to a control diet for an additional 28 days (Period II). On the last day of both periods, mammary gland biopsies were taken to study genome-wide differences in lipid metabolism gene expression.

An oil containing EPA and DHA from transgenic Camelina sativa to replace marine fish oil in feeds for Atlantic salmon (Salmo salar L.)

Project description:New de novo sources of omega 3 (n-3) long chain polyunsaturated fatty acids (LC-PUFA) are required as alternatives to fish oil in aquafeeds in order to maintain adequate levels of the beneficial fatty acids, eicosapentaenoic and docosahexaenoic (EPA and DHA, respectively). The present study investigated the use of an EPA+DHA oil derived from a transgenic Camelina sativa in feeds for Atlantic salmon (Salmo salar) containing low levels of fishmeal (35 %) and fish oil (10 %), reflecting current commercial formulations, to determine the impacts on intestinal transcriptome, tissue fatty acid profile and health of farmed salmon. Post-smolt Atlantic salmon were fed for 12-weeks with one of three experimental diets containing either a blend of fish oil/rapeseed oil (FO), wild-type camelina oil (WCO) or transgenic camelina oil (DCO) as added lipid source. The DCO diet did not affect any of the fish performance or health parameters studied. Analyses of the mid and hindgut transcriptomes showed only mild effects on metabolism. Flesh of fish fed the DCO diet accumulated almost double the amount of n-3 LC-PUFA than fish fed the FO or WCO diets, indicating that these oils from transgenic oilseeds offer the opportunity to increase the n-3 LC-PUFA in farmed fish to levels comparable to those found twelve years ago.

Effect of Supplementing Linseed in the Transition Period on Mammary Gland Tissue of dairy Cows

Project description:The aim of this study was to determine the effects of linseed dietary supplementation on gene expression in the mammary gland of grazing dairy cows. Milk composition and gene expression in the mammary gland tissue were evaluated in dairy cows supplemented with linseed. The linseed supplementation improves the health and nutrition quality aspects of dairy milk, but also affects the gene networks expression signature associated with cellular growth and proliferation, cell-death, signalling, nutrient metabolism, and immune response, and in turn, the mammary gland integrity and health. The experiment was carried out in a complete randomized blocked designed structure comprising 14 Holstein-Friesian cows (6 second parity, 2 third parity and 6 older cows), selected from a 550-cow herd. Cows were paired in 7 blocks on the basis of similarity in parity (second parity, third parity and older cows), expected date of calving, and milk performance in the previous lactation (in order of priority). Cows within each block were randomly allocated to one of two treatment groups, “Omega” or “Control”. The dietary Omega treatment consisted of a basal diet supplemented with a concentrate-mixture including linseed on a dry matter (DM) basis, whereas cows in treatment group Control were supplemented with a concentrate mixture without linseed. Linseed was chosen because it is rich in c9,c12,c15-18:3 (ALA). Concentrate mixtures were fed with a concentrate dispenser. Experimental treatments started 3 weeks before the expected calving date (wk -3) and lasted until 6 weeks after calving (wk 6).

Identifying gene expression differences induced by diets that lead to higher omega-3 fatty acid deposition in beef cows

Project description:The objective of this project is identifying differentially expressed (DE) genes which are associated with higher omega-3 fatty acids deposition in beef cows. Omega-3 fatty acids have been found to influence meat flavor and are beneficial to human health. Supplementation of livestock diets with flaxseed, a rich source of ë±-linolenic acid, is the most common means of producing omega-3 fatty acid-enriched animal products. Towards the goal of enhancing beef fatty acid composition, 64 crossbred cull cows (~30 months of age) with similar breed composition were randomized by weight/body condition, and fed one of four 50:50 forage:concentrate diets on a DM basis (16 cows/treatment), containing ground barley grain with either hay or silage, supplemented with 0 or 15% ground flaxseed (DM basis). Cows were slaughtered after spending 140 days on the treatment diets. Five cows from each of the four diets were selected for transcriptional analysis based on FA profiles of the kidney fat collected at slaughter. RNA was isolated from Longissimus thoracis muscle, subcutaneous and kidney fat of each cow (20 samples/tissue) and hybridized in duplicate to BOMC 24K 60-mer microarrays. Differential gene expression between flax-fed and non-flax-fed cows as well as identifying those genes associated with fatty acid metabolism were studied.

Proteome dataset of peripheral blood mononuclear cells in postpartum dairy cows supplemented with different sources of omega-3 fatty acids

Project description:This article contains raw and processed data related to research published by Kra et al. [1]. There is a scarce knowledge on the proteome of peripheral blood mononuclear cells (PBMC) during the transition period in dairy cows. In human research, proteomics PBMC is used in order to gain insight into inflammatory diseases and syndromes. Dietary fats, and specifically omega-3 (n-3) FA, can moderate the immune fluctuation caused by parturition through improvements of the immune function [2]. Therefore, this study aim was to characterize the changes that may occur in proteome of PBMC during transition, as influenced by different n-3 FA supplementation. Proteomics data of PBMC was obtained from postpartum dairy cows supplemented peripartum with either encapsulated saturated fat (CTL), encapsulated flaxseed oil that is enriched with ALA (α-linolenic acid; FLX) or encapsulated fish oil that is enriched with EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid; FO).The analysis was done by liquid chromatography-mass spectrometry from PBMCs protein extraction. The cells were collected from six cows per treatment during the 1st week postpartum. Quantification of differential abundance between groups was done using MS1 intensity based label-free. Label-free quantitative shotgun proteomics was used for characterization. This novel dataset of proteomics data from PBMC contains 3807 proteins; 44, 42 and 65 were differently abundant (P ≤ 0.05 and FC ± 1.5), in FLX vs. CTL, FO vs. CTL and FLX vs. FO, respectively; these findings are discussed in our recent research article [1]. The present dataset of PBMC proteome adds new information regarding the effects of n-3 FA on the immune system, while providing reference for PBMC proteome in postpartum dairy cows.

Differential effects of krill oil and fish oil on the hepatic transcriptome in mice

Project description:Dietary supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFAs), specifically the fatty acids docosahexaenoic acid (DHA; 22:6 ω-3) and eicosapentaenoic acid (EPA; 20:5 ω-3), is known to have beneficial health effects including improvements in glucose and lipid homeostasis and modulation of inflammation. To evaluate the efficacy of two different sources of ω-3 PUFAs, we performed gene expression profiling in the liver of mice fed diets supplemented with either fish oil or krill oil. We found that ω-3 PUFA supplements derived from a phospholipid krill fraction (krill oil) downregulated the activity of pathways involved in hepatic glucose production as well as lipid and cholesterol synthesis. The data also suggested that krill oil-supplementation increases the activity of the mitochondrial respiratory chain. Surprisingly, an equimolar dose of EPA and DHA derived from fish oil modulated fewer pathways than a krill oil-supplemented diet and did not modulate key metabolic pathways regulated by krill oil, including glucose metabolism, lipid metabolism and the mitochondrial respiratory chain. Moreover, fish oil upregulated the cholesterol synthesis pathway, which was the opposite effect of krill supplementation. Neither diet elicited changes in plasma levels of lipids, glucose or insulin, probably because the mice used in this study were young and were fed a low fat diet. Further studies of krill oil supplementation using animal models of metabolic disorders and/or diets with a higher level of fat may be required to observe these effects.
