Effect Of Feeding

The COMA report on The Nutritional Aspects of Cardiovascular Disease (1994) recommended that the intake of long chain n-3 polyunsaturated fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), by the UK population should double. EPA and DHA in the human diet are derived principally from oily fish. The aim of this experiment was to determine the effect of increasing levels of fish oil in the diet at two levels of vitamin E supplementation, on intake, milk production, the extent of uptake of EPA and DHA into milk fat at levels exceeding those investigated to date, and the effect of a dietary supplement of vitamin E on fatty acid content.

Development In Vitro

To determine whether serum supplementation influenced fatty acid content of bovine blastocysts and whether vitamin E addition to culture medium containing serum could improve development in vitro, cleaved eggs were cultured in synthetic oviduct fluid supplemented with bovine serum albumin (BSA, 0.4% w/v, fraction V) (SVBSA), fetal calf serum (FCS, 10% v/v) (SFCS) or FCS (10% v/v) plus 100 μM vitamin E (SFCS + E). Blastocyst yields were recorded and fatty acid composition was determined by gas chromatography. Day 7 blastocysts were incubated with [2-14C] pyruvate for 3 h and then fixed for cell counts. Yields of good quality blastocysts were greatest from cleaved eggs cultured in serum-free conditions (P < 0.01). In the presence of serum, supplementation with vitamin E increased both total and good quality blastocyst yields (P < 0.01). Presence of serum increased fatty acid content (mean ± SEM) of blastocysts (SVBSA v. SFCS = 57 ± 2  v. 74 ± 2 ng embryo−1; P < 0.001). In contrast, pyruvate metabolism was greater in blastocysts produced without serum (27 ± 3 v. 21 ± 3 picomoles embryo−13 h−1; P < 0.01) but, on a per cell basis, no differences were detected. Addition of vitamin E to the serum-supplemented formulation did not alter either the fatty acid content (73 ± 2 ng embryo−1) or pyruvate metabolism index (19 ± 1 pmol embryo−13 h−1) of SFCS + E blastocysts. Thus, despite lipid accumulation, supplementary vitamin E improved blastocyst yields in embryos exposed to serum.

Study Objective

Abstract The study objective was to assess the contribution of fat source and vitamin E (VE) supplementation on tissue tocopherol concentration, antioxidant status, and fatty acid composition in the backfat of pigs at heavy slaughter weight (149.38 ±1.56 kg). A total of 64 individually-fed pigs (32 barrows, 32 gilts; 28.41 ±0.83 kg) were randomly assigned to 8 dietary treatments in a 4 × 2 factorial arrangement. Fat treatments included corn-starch (CS), tallow (TW), corn oil (CO) and coconut oil (CN). VE supplementation levels were 11 and 200 IU/kg. Loin muscle, backfat, and liver samples were collected at slaughter. Data analysis were performed by ANOVA using GLM in SAS. No interactions between dietary fat source and VE supplementation were observed. Increasing dietary VE level from 11 to 200 IU/kg increased (P < 0.001) the tocopherol concentration in both liver (4.73 vs. 21.06 ppm wet liver) and loin muscle (1.25 vs. 2.67 ppm wet muscle). Pigs from the CO group had higher liver SOD activity (P < 0.05) than the other treatments (CS 22.51, TW 22.67, CO 24.40, and CN 20.92 U/mg protein). Pigs from the CN group had the highest (P < 0.05) total saturated fatty acid content (CS 44.33, TW 40.33, CO 36.29, and CN 51.70%), but the lowest (P < 0.05) total polyunsaturated fatty acid content (CS 9.26, TW 9.80, CO 25.41, and CN 8.75%) and iodine value (CS 56.61, TW 60.66, CO 77.83, and CN 49.90) in the backfat. Pigs from the TW group had the highest (P < 0.05) total monounsaturated fatty acid content (CS 46.40, TW 49.87, CO 38.30, and CN 39.56%) in the backfat. Under conditions of this study, a higher level of VE supplementation increased liver and muscle tocopherol concentrations whereas dietary fat sources altered liver antioxidant activity and fatty acid composition in the backfat.
