Description
Summary:The effect of combining probiotics (Lactobacillus plantarum and Lactobacillus fermentum) with flaxseed (a source of n-3 PUFAs) on the lipid metabolism and long-chain fatty acid profile of conventional piglets after weaning was studied. The levels of total lipids and high-density lipoproteins cholesterol decreased from Day 7 post-weaning, whereas levels of low-density lipoproteins cholesterol, total cholesterol and triglycerides did not change significantly in piglets with supplemented diet. The levels of alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) increased seven days post-weaning; however, the levels of dihomogamma-linolenic acid and arachidonic acid (AA) were lower and linoleic acid (LA) higher in synbioticsfed piglets compared with controls. This study demonstrates the efficacy of conversion of ALA to EPA and DHA, where delta-6-desaturase was predominantly used for n-3 polyunsaturated fatty acid synthesis from ALA at the expense of n-6 PUFAs from LA, which caused rapid increase in EPA/AA ratio on Day 14 after weaning. Combination of probiotic cheese and flaxseed is a good dietary supplement for piglets before weaning, helping them to adapt to change in diet more easily by regulating changes in lipid metabolism and vitality, and reducing the likelihood of chronic diseases.
