In this trial we aimed to assess the effects of dietary supplementation of 4-O-methyl-glucuronoarabinoxylan (4OMG) on growth performance, thigh meat quality and small intestine development of female Partridge-Shank broilers. A total of 240 1-day-old female Partridge-Shank broilers were randomly distributed to four groups with three replicates of 20 within each group. Groups received either 0, 15, 20 or 25 g 4OMG/kg DM of diet. During the whole experiment of 60 days, broilers had ad libitum access to water and feed. At pen level, feed intake was recorded daily and broilers were weighed at the start and end of the experiment. For each group, three pens with a total of 20 broilers were randomly selected to determine the thigh meat quality and the small intestine development of broilers. Broilers fed diets with higher 4OMG had greater final liveweight (P = 0.004), daily bodyweight gain (P = 0.004) and gain-to-feed ratio (P < 0.001), muscle pH values (P = 0.031) and redness (P = 0.001), duodenal weight index (P = 0.042), jejunal (P = 0.043) and ileal length (P = 0.049), duodenal (P < 0.001) and ileal villus height (P = 0.008), but lower percentage of dead birds (P < 0.001), drip loss (P = 0.042) and shear force value (P = 0.043) of the thigh muscles. These results indicate that increasing dietary supplementation of 4OMG may improve growth performance and meat quality of female Partridge-Shank broilers through better development of small intestine.

The objective of this study was to evaluate the effects of dietary energy levels on growth performance, rumen fermentation and bacterial community, and meat quality of Holstein-Friesians bulls slaughtered at different ages. Thirty-six Holstein-Friesians bulls (17 months of age) were divided into a 3 × 3 factorial experiment with three energy levels (LE, ME and HE; metabolizable energy is 10.12, 10.90 and 11.68 MJ/kg, respectively) of diets, and three slaughter ages (20, 23 and 26 months). Results indicated that bulls fed with ME and HE diets had higher dry matter intake, average daily gain, and dressing percentage at 23 or 26 months of age. The ME and HE diets also reduced bacterial diversity, altered relative abundances of bacteria and produced lower concentrations of acetate, but higher butyrate and valerate concentrations in rumen fluid. Increasing in dietary energy and slaughter age increased the intramuscular fat (IMF) and water holding capacity. In summary, Holstein-Friesians bulls fed with ME and HE diets, slaughtered at 23 and 26 months of age could be a good choice to produce beef with high IMF. Slaughter age may have less influence than dietary energy in altering fermentation by increasing amylolytic bacteria and decreasing cellulolytic bacteria, and thus, further affecting meat quality.

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.
