Selenium Auricularia cornea culture (SAC) is a new source of organic selenium. Two experiments were conducted to determine the available energy of SAC fed to pigs and to evaluate the effects of dietary SAC supplementation on growth performance, serum biochemical profiles, fecal short chain fatty acids (SCFA), meat quality, tissue selenium concentration, and oxidative stability of fresh meat in growing-finishing pigs. In Experiment (Exp.) 1, 12 barrows with average body weight (BW) of 42.40 ± 5.30 kg were randomly allotted to two groups and fed the basal diet and SAC-supplemented diet, individually. In Exp. 2, 96 growing-finishing pigs (BW: 91.96 ± 7.55 kg) were grouped into four dietary treatments; each treatment contained six replicates with four pigs per replicate. The four treatments fed a control diet and three experimental diets supplemented with 0.6%, 1.2%, and 2.4% SAC, respectively. The trial lasted for 45 days. The results revealed that digestible energy (DE) of SAC was 11.21 MJ/kg. The average daily gain (ADG) was improved in pigs fed 1.2% and 2.4% SAC during day 24 to 45 and the overall period. Dietary 1.2% and 2.4% SAC supplementation had a lower F/G (p < 0.05) than the control diet during different stages. Dietary SAC supplementation increased fecal butyrate contents (p < 0.05), and pigs fed 1.2% and 2.4% SAC diets had a higher MCT1 mRNA expression (p = 0.04) in the colon. Pigs fed 2.4% SAC had higher GSH-Px contents (p < 0.05) in serum, liver, and longissimus dorsi muscle (LDM) than those in the control group. The 2.4% SAC-supplemented group revealed a higher Se content (p < 0.05) in LDM and a lower MDA concentration (p < 0.05) in fresh meat during the simulated retail display on day six. In conclusion, this study suggested that SAC was more effective in improving growth, enhancing the antioxidant status, depositing Se in muscle, and increasing meat oxidative stability of pigs.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.

Abstract Two experiments were conducted to evaluate the effects of feeding fermented mixed feed (FMF) on performance, meat quality, muscle fatty acids profile and antioxidant ability in finishing pigs. In experiment 1, 225 finishing pigs were allocated into 3 dietary treatments. Pigs in 3 groups were fed a basic diet or basic diet supplemented with 4% and 8% of FMF. After 35 days of the experiment, growth performance was evaluated. In experiment 2, 600 pigs were distributed into 3 treatments, which were fed with a basic diet or basic diet supplemented with 5% and 10% of FMF. At the end of the experiment, 24 pigs were slaughtered for the determination. In experiment 1, feeding 8% FMF improved (P &lt; 0.05) ADG and decreased (P &lt; 0.05) F/G compared with CON. In experiment 2, compared with CON, dietary supplementation with 10% FMF decreased (P &lt; 0.05) F/G. Moreover, the ADFI and ADG were tended to be higher in pigs fed the FMF diet. Feeding 10% FMF increased (P &lt; 0.05) loin muscle area, a* value, marbling score, intramuscular fat (IMF), and inosine acid (IMP) and decreased (P &lt; 0.05) drip loss and shear force of longissimus thoracis (LT) muscle. The percentages of C18:1ω-9c, C18:2ω-6c, and C20:4ω-6c in LT muscle were increased (P &lt; 0.05) in pigs fed 10 % FMF diet. Furthermore, greater (P &lt; 0.05) SOD and GSH-Px activities were observed in 10 % FMF group in serum and LT muscle of pigs. Collectively, the present study suggested that dietary FMF supplementation improved the growth performance, meat quality parameters, unsaturated fatty acids proportions, and antioxidant ability.
