Abstract
Piglets during the weaning period, are particularly vulnerable to external factors, causing damage to the intestinal epithelium, which is an important site of nutrient acquisition. Fermented products lower the pH of the gastrointestinal tract, inhibit the proliferation of pathogenic microorganisms, protect the intestinal epithelium from pathogen attack, contributing to the preservation of its functionality. In addition, fermentation modulates the intestinal microflora of piglets, and normal microflora is responsible for availability, digestion and absorption of nutrients. A properly balanced diet is an essential element for proper bone development and function, and mineral deficiencies result in decreased bone mass, weakened bones and increased risk of fractures. The purpose of this study is to present the effect of post-extraction fermented rapeseed meal (FRSM) on the digestibility of minerals and their concentrations in the blood, as well as on the mineral content of femoral bone. The study was conducted on 300 piglets from 28 to 92 days of age. Piglets on the basis of analogs with sex and body weight were assigned to six groups: NC- basal diet (negative control) and the proportion of 8%, 10%, 12%, 15%, 25% FRSM in the FR-8, FR-10, FR-12, FR-15, FR-25 groups, respectively. Before slaughter (64th day of the experiment), blood was drawn from 6 animals per group for analysis for mineral content. Seven days before slaughter, feces were collected in the morning for analysis of digestibility indices of essential minerals. Fecal samples were collected for 5 consecutive days. At the end of the experiment, 6 piglets from each group (the same animals from which blood was drawn) were slaughtered, and femurs were taken for mineral content analysis. Piglets fed a compound with FRSM showed an increase in Cu, Zn digestibility (p < 0.001). The addition of FRSM also caused an increase in digestibility of P, Fe, Mg, with the highest values recorded in the FR-15 and FR-25 groups. Piglets fed a compound with FRSM showed an increase in plasma phosphorus concentration (p < 0.001), an increase in Cu and Fe concentration was also observed, obtaining the highest concentration at FRSM 25%.The groups with fermented diet showed an increase in P, Ca, Mg, Cu, Fe, Zn content in femur. In conclusion, fermented rapeseed meal increases the bioavailability of minerals, which may have a positive effect on bone strength in pigs.
