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.

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.

AbstractThe current experiment aimed at assessing the effects of dietary supplementation of guanidino acetic acid (GAA) on growth performance, thigh meat quality and development of small intestine in broilers. A total of 360 1-day-old female broiler chicks were distributed randomly to four groups of 90 birds each, and each group received GAA dosages of 0, 0.4, 0.8 and 1.2 g/kg of feed dry matter. During the whole experiment of 60 days, broilers hadad libitumaccess to water and feed and the feed intake was recorded daily. All broilers were weighed before and after the experiment, and 30 broilers of each group were selected randomly to slaughter at the end. Increasing dietary supplementation of GAA increased final live weight and daily body weight gain, gain-to-feed ratio, thigh muscle pH value and fibre diameter of broilers, but decreased daily feed intake, drip loss, cooking loss, shear force value, hardness, gumminess and chewiness of thigh meat. In addition, increasing supplementation of GAA quadratically increased duodenal, jejunal and ileal villus height and width and ratio of villus height to crypt depth, but decreased crypt depth. The results indicated that GAA as a feed additive may support better development of small intestine, thereby resulting in improvement of growth performance and meat quality of broilers.
