Evaluation of Red Yeast Rice Residue as an Alternative Feed Ingredient in Growing-Finishing Pig Diets
This study aimed to evaluate the effects of graded levels of red yeast rice residue (RYRR) on the growth performance, nutrient digestibility, and fecal microbiota of growing-finishing pigs. A total of 144 pigs were randomly allocated into four dietary treatment groups, over a 75-day experimental per...

| description | This study aimed to evaluate the effects of graded levels of red yeast rice residue (RYRR) on the growth performance, nutrient digestibility, and fecal microbiota of growing-finishing pigs. A total of 144 pigs were randomly allocated into four dietary treatment groups, over a 75-day experimental period. The study comprised a control group and three dietary supplementation groups receiving RYRR. The control (CON) group was fed a two-phase diet tailored to the pigs’ body weight, while the RYRR groups were provided with the CON diet, where corn, soybean meal, puffed soybeans, and wheat shorts were substituted with 5%, 10%, and 20% of RYRR. Supplementation with 10% RYRR enhanced the apparent digestibility of gross energy, dry matter, and crude fiber, while reducing the feed-to-gain ratio and serum triglyceride levels (<i>p</i> < 0.05). Microbiological analyses revealed that short-chain fatty acid-producing bacteria (<i>Anaerotignum</i> and <i>Lachnospiraceae_UCG-009</i>) were biomarkers in pigs fed the RYRR supplementation diets (<i>p</i> < 0.05). These results demonstrated that RYRR supplementation of the diet exerted beneficial effects on promoting nutrient digestibility as well as modulating the fecal microbiota of pigs, and the recommended proportion of RYRR added to the growing-finishing pigs’ diet is 10%. |
