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 < 0.05) ADG and decreased (P < 0.05) F/G compared with CON. In experiment 2, compared with CON, dietary supplementation with 10% FMF decreased (P < 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 < 0.05) loin muscle area, a* value, marbling score, intramuscular fat (IMF), and inosine acid (IMP) and decreased (P < 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 < 0.05) in pigs fed 10 % FMF diet. Furthermore, greater (P < 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.
