title: Effects of Aspergillus niger fermented rapeseed meal on nutrient digestibility, growth performance and serum parameters in growing pigs.
abstract: The aim of the present study was to investigate the influences of Aspergillus niger fermented rapeseed meal (FRSM) on growth performance and nutrient digestibility of growing pigs. A total of 72 growing pigs (body weight = 40.8 ± 2.1 kg) were used in feeding trials, lasting for up to 42 days, and were randomly allotted to one of three diets, including a corn-soybean meal control diet as well as two experimental diets containing 10% unfermented rapeseed meal (RSM) or 10% FRSM. The results showed that average daily gain and feed conversion ratio of pigs fed FRSM were superior (P < 0.05) to that of pigs fed unfermented RSM and did not differ from the control. Pigs fed control diet had higher (P < 0.05) total tract apparent digestibility for dry matter, protein, calcium and phosphorus than pigs fed unfermented RSM diet and did not differ from the FRSM diet. Pigs fed FRSM had lower levels (P < 0.05) of serum aspartate transaminase compared to unfermented RSM. In conclusion, solid state fermentation using Aspergillus niger may improve the growth performance and nutrient digestibility of RSM for pigs and FRSM is a promising alternative protein for pig production.
