Abstract

Simple SummaryThe use of fermented products, including fermented soybean meal, and recently also fermented rapeseed meal, in the diet of pigs and other animals is becoming increasingly popular. A diet containing protein components from which anti-nutrients and allergenic substances have been eliminated by means of fermentation stimulates beneficial gastrointestinal microflora, resulting in improvement in metabolic processes and thus improved animal health.The aim of the study was to assess the effect of fermented soybean meal (FSBM) and/or rapeseed meal (FRSM) on the redox status of blood and tissues in piglets. The experiment was conducted on 150 28-day-old weaned piglets divided into five groups. Piglets in the control group received standard diets with soybean meal. Animals in the experimental groups received diets in which a portion of the soybean meal was replaced with FRSM and/or FSBM: group FR—8% FRSM; group FR/FS—6% FRSM and 2% FSBM; group FS/FR—2% FRSM and 6% FSBM; and group FS—8% FSBM. Group FR/FS showed an increase in total antioxidant potential of plasma (FRAP) and low-molecular-weight antioxidants, i.e., vitamin C, urea, uric acid, and albumin, as well as an increase in catalase activity. Blood levels of lipid hydroperoxides (LOOH) and malonyl dialdehyde (MDA) were decreased. A reduction in lipid peroxidation due to the use of FR/FS was also indicated by a decrease in liver MDA and jejunum wall LOOH levels. Increases in superoxide dismutase (SOD) and catalase (CAT) activity and vitamin C levels in these tissues were also noted. The results of the study indicate that the inclusion of fermented rapeseed meal in the diet (6%) in combination with soybean meal (2%), improved the redox status of the weaners.

Summary

Introduction

One of the most commonly used protein components in feed for pigs is soybean meal (SBM). Due to lower protein digestibility and lower lysine content compared to SBM, and presence of anti-nutritional factors (ANFs) such as tannins, phytic acid, crude fiber, and especially glucosinolates, the use of rapeseed meal in the diet of swine is limited [3]. Research by Yuan et al [10] in piglets showed that fermented soybean meal (FSBM) had a beneficial impact on their growth performance, nutrient digestibility, and the fecal microbiome. An earlier experiment conducted by Feng et al [12] demonstrated that the addition of FSBM to the diet of weaned piglets increased activities of intestinal enzymes, improved nutrient digestibility and had beneficial influence on growth performance parameters. One of the effects of fermentation is an increase in the amount of low-molecular-weight peptides that exhibit antioxidant properties [17]
