Effect of fermented corn-soybean meal on carcass and meat quality of grower-finisher pigs

Influence of Fermented Broccoli Residues on Fattening Performance, Nutrient Utilization, and Meat Properties of Finishing Pigs

The study determined the impacts of dietary fermented residues' (FBR) inclusion on growth, nutrient utilization, carcass characteristics, and meat properties in fattening pigs. Seventy-two robust pigs were randomly assigned to two experimental groups (Duroc × Landrace × Yorkshire, thirty-six pigs each). Each group was subjected to a 52-day trial, during which they received either a corn-soybean meal-based diet or diet enhanced with a 10% addition of FBR. Consequently, adding 10% FBR caused a significant decrease in the digestive utilization of crude dietary components in fattening pigs (p < 0.05) but showed no significant impact on the growth performance. Additionally, FBR inclusion increased the marbling scores (p < 0.05) and total antioxidant functions (p < 0.05) of muscle tissues, indicating improved meat quality. Gender affected backfat depth, with barrows showing thicker backfat depth. In conclusion, dietary supplementation with 10% FBR in finishing pigs influenced the meat quality by improving the marbling score and antioxidant performance while reducing digestibility without compromising growth performance.

Effects of fermented broccoli stem and leaf residue on growth performance, serum characteristics and meat quality of growing pigs

The aim of this study was to evaluate the effects of fermented broccoli stem and leaf residue (FBR) on the growth performance, serum biochemical characteristics, and meat quality of growing pigs. A total of 72 growing pigs (Durox × Landrace × Yorkshire) were subjected to three dietary treatments with different levels (0%, 5% and 10%) of FBR with three replicates for an experimental period of 70 day. The average daily feed intake of growing pigs was higher (p < 0.05) in the 5% FBR treatment compared with the control group (0% FBR). The serum urea nitrogen content in growing pigs was lower (p < 0.05) in the 5% and 10% FBR treatments. The lightness value was higher (p < 0.05) in the longissimus dorsi muscle of pigs fed 5% and 10% FBR diets compared with the control group, and the yellowness value was increased in pigs fed the 10% FBR diet compared with pigs fed the control diet. Overall, the beneficial effects of FBR supplementation on serum biochemical parameters, and meat colour without undermining the growth performance indicate that up to 10% FBR could be used in diets to enhance the production of growing pigs.

Effects of Feeding Fermented Medicago sativa (Plus Soybean and DDGS) on Growth Performance, Blood Profiles, Gut Health, and Carcass Characteristics of Lande (Meat) Geese

The objective was to investigate the effects of alfalfa (Medicago sativa Linn)-mixed silage fermentation material (AMSFM) on various aspects of growth, function, and carcass characteristics of Lande (meat) geese. Based on a previous study, we used the following AMSFM: 80% Alfalfa +10% soybean meal +10% DDGS ensiled for 45 days. Lande geese, n = 264, 77 days of age, were randomly allocated into four groups with six replicates in each group. Control geese were fed a basal diet, whereas experimental groups were fed a basal diet supplemented with 6, 12, or 24% AMSFM. The experiment lasted 21 days. The AMSFM promoted some aspects of growth, with increase (p < 0.05) in leg muscle rate, lean meat rate, muscle protein content, and total energy content of leg muscle plus concurrent decreases (p < 0.05) in crude fat content and abdominal fat rate in chest muscle. In addition, AMSFM increased (p < 0.05) glutathione content in chest and leg muscles and serum superoxide dismutase activity, and it reduced (p < 0.05) muscle malondialdehyde content and serum concentrations of triglycerides, total cholesterol, urea, and aspartate aminotransferase, consistent with good liver and kidney function. Moreover, AMSFM improved (p < 0.05) ileum morphology. In conclusion, the optimal supplemented rate of AMSFM in the meat geese diet (12%) improved immunity and antioxidant status and enhanced growth performance and carcass characteristics of meat geese.
