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.

A total of 150 broiler chicks were used to determine the impact of dietary cinnamon bark powder (CBP; Cinnamomum verum) on breast meat quality, growth performance, and carcass characteristics of birds under coccidiosis, as one of the protozoan parasitic diseases. A total of 5 replicates of birds received 1 of the following 6 groups for 34 days: control groups (1 and 2) received a basal diet without the addition of CBP or salinomycin; group 3 received a basal diet with 0.066 g salinomycin; groups 4–6 were given a basal diet supplemented with 2, 4, and 6 g CBP/kg feed, respectively. On day 21, 4 × 104/100 µL of Eimeria tenella oocysts/bird were challenged, except for the negative control (NC). At the end of the experimental trial, five birds/group were sampled for carcass characteristics and breast attributes. Overall, emeriosis negatively affects slaughter body mass, carcass yield, and the majority of carcass characteristics in birds, and cinnamon can mitigate these effects. Cinnamon groups, particularly at the 2 g level, alleviated the negative effect on performance caused by coccidia infestation to the same or greater extent as the negative control and salinomycin treatment groups. Furthermore, when compared with the other experimental groups, the addition of cinnamon improved some physicochemical properties with some affecting meat quality, such as decreasing MFI and increasing toughness in cinnamon-treated groups. In summary, it can be concluded that CBP can enhance the shelf life, carcass, and quality of birds’ meat by maximizing the productive performance efficiency and breast meat productivity of birds under coccidiosis infestation. Further research is required to investigate the use of cinnamon to optimize the quality of meat and the productivity of both healthy and diseased broilers.

The present study aimed to investigate the effects of dietary supplementation with powdered peanut skin (PS) as natural antioxidant and growth promoter on growth performance, carcass characteristics, serum metabolites and meat quality of Cobb broiler chickens. A total of 240 unsexed Cobb 500 1-week-old broiler chicks were randomly assigned to four treatment groups with six replicates. The dietary treatments consisted of the basal diet as control and PS groups (1.0, 2.0, and 3.0 PS g/kg). Results showed that the highest values (P < 0.01) of live bodyweight and bodyweight gain were observed in the control group at 3 weeks of age and during the period of 1–3 weeks of age, respectively compared with all levels of PS. During 1–3 weeks of age, feed intake per day chicks fed the diet containing PS levels decreased numerically (P > 0.01) with increased levels of PS compared with the control. Supplementing 1.0 or 3.0 g/kg of PS insignificantly enhanced feed conversion ratio at 1–6 weeks of age. Dietary treatments significantly depressed giblets (P = 0.002), thigh (P = 0.0.027) and abdominal fat percentages (P > 0.0.1), however, increased (P = 0.004) breast percentage of broiler chicks at 6 weeks of age. The lowest value of serum creatinine and urea achieved by chicks fed diet contained 3.0 PS g/kg diet. Also, high density lipoprotein cholesterol in addition to triglycerides were significantly (P < 0.05 and P < 0.01) decreased with increasing level of PS supplementation. It can be concluded that PS as a phytogenic additive could be used as a supplementation to broiler diets to lower abdominal fat in carcass and cholesterol, creatinin and urea in blood. Sensory characteristics were not affected except that appearance was improved. Water-holding capacity was also improved.
