The effects of dietary extruded linseed (EL) on growth performance, meat quality, and lipid profile ofSemimembranosusandLongissimus lumborummuscles of 81 Sarda lambs were studied in a 3 × 3 design: EL content (0%, 10%, and 20%) of maternal dietary concentrate fed from 20 d to parturition to 60 d of lactation and EL content (0%, 10%, 20%) of lamb concentrate fed after weaning for 30 d. The basal diet was composed of alfalfa and meadow hay during pregnancy and alfalfa hay during lactation. At slaughter, carcass and meat quality were evaluated. Sensory quality ofSemimembranosusfrom 0% and 20% EL lambs was assessed. Both maternal and postweaning diets affected growth performance, with higher body weights recorded with the 10% EL concentrate. Carcass and meat quality were not affected by diet. Saturated and monounsaturated FA decreased and n-3 polyunsaturated FA increased with increasing EL content in lamb diet. An increase in vaccenic and rumenic acid was associated with the EL content of the maternal diet. Both diets increased the n-6/n-3 FA ratio. No differences in acceptability were detected by consumers among groups. It is concluded that EL supplementation and early life nutrition can influence performance and FA metabolism in growing lambs.

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 This study investigated the effects of encapsulated citral (CIT) and cinnamaldehyde (CIN) on growth performance, intestinal morphology and meat quality in broilers. A total of 320 0-day-age male broilers (Cobb 500) were allocated 32 pens with 8 pens per treatment. The treatments included: 1) Corn-wheat-SBM basal diet (negative control); 2) basal diet with 30 ppm avilamycin premix (positive control); 3) basal diet with 50 ppm encapsulated CIT and CIN (CCL); 4) basal diet with 100 ppm encapsulated CIT and CIN (CCH). There were no significant differences between treatments in growth performance (P > 0.05) at each feeding stage. Additionally, birds had similar relative organ weights of heart, liver, spleen and bursa (P > 0.05). The higher ratios of villus height to crypt depth (VCR; P ≤ 0.05) were detected in broilers fed either CCL or CCH, with an average being 14.67 and 15.13 in the duodenum, and 15.13 and 13.58 in the jejunum, respectively. Regarding meat quality, a higher pH value (pH = 6.21) in the breast was observed in 24-h post mortem chickens fed CCL (P ≤ 0.05). No significant differences of pH were detected in the breast in 96-h post mortem birds. The breast color (redness, yellowness, and lightness) in either 24-h or 96-h post mortem chickens was not significantly different among treatments (P > 0.05). No change in purge loss (%) was observed in the breast after 48 h. The severity of white striping (WS) or woody meat (WB) was higher in the positive control (WS = 0.58; WB = 0.15) than in other treatments (P ≤ 0.05). In conclusion, dietary treatment with encapsulated CIT and CIN improved gut morphology and meat quality of broilers by increasing VCR in the small intestine and reducing the severity of WS/WB in the breast, respectively, without affecting growth performance.

An experiment was conducted with 60 day old Cobb-500 broiler chicks for a period of 28 days with the aims of investigating the effects of different level of garlic powder on growth performance, carcass characteristics and meat quality of broilers to produce safe broiler meat. The experimental broiler chicks were divided randomly into four different groups with three replications having 5 chicks in each. Maize-soybean based diet was used as basal diet for group 1. Basal diet was supplemented with 1%, 2% and 3% garlic powder on fresh basis for group 2, 3, and 4 respectively. The broiler of groups 2, 3, and 4 were showed significantly (p>0.05) higher body weight than control group at 4 weeks of age. Feed conversion ratio of group 2, 3, and 4 were significantly (p>0.05) lower than group 1. Group 2 was given significantly lower fat percentage than other groups. Group 3 and 4 showed more or less similar fat content but lower than control groups. Thus, it may be concluded that garlic powder may be used in chicken diet.Bang. J. Anim. Sci. 2016. 45 (2): 79-83

Didancao (Elephantopus scaber L.) has been used as a traditional herbal medicine and has exhibited a beneficial role in animal health. This study aimed to investigate the effects of dietary supplementation with E. scaber on growth performance, meat quality, intestinal morphology, and microbiota composition in ducks. A total of 480 Jiaji ducks (42 days old, male:female ratio = 1:1) were randomly assigned to one of four treatments. There were six replicates per treatment, with 20 ducks per replicate. The ducks in the control group (Con) were fed a basal diet; the three experimental groups were fed a basal diet supplementation with 30 (T1), 80 (T2), and 130 mg/kg (T3) of E. scaber. After a 48-day period of supplementation, growth performance, meat quality, intestinal morphology, and microbiota composition were evaluated. The results showed that no differences were observed in the final body weight, average daily feed intake, and average daily gain among the four groups. Compared with that in the Con group, the feed conversion in the T1 and T2 groups was increased significantly; the T2 group was shown to decrease the concentration of alanine aminotransferase in serum; the T3 group was lower than the Con group in the concentration of aspartate aminotransferase and was higher than the Con group in the concentration of high-density lipoprotein-cholesterol. The highest concentration of creatinine was observed in the T1 group. The T2 group was higher than the Con group in the contents of Phe, Ala, Gly, Glu, Arg, Lys, Tyr, Leu, Ser, Thr, Asp, and total amino acids in the breast muscle. Moreover, the T2 group was higher than the Con group in the contents of meat C18:2n−6 and polyunsaturated fatty acid. The concentration of inosinic acid in the T1, T2, and T3 groups was significantly higher than that in the Con group. However, the Con group was higher than the T2 or T3 group in the Zn content. The T2 group was lower than the Con group in the jejunal crypt depth. The T3 group was higher than the Con group in the ileal villus height and the ratio of villus height to crypt depth. In addition, the T3 group had a trend to significantly increase the abundance of Fusobacteria. Compared with the Con group, the T1 and T2 groups displayed a higher abundance of Subdoligranulum. Collectively, dietary supplementation with 80 mg/kg of E. scaber improves meat quality and intestinal development in ducks.

Abstract Background: With increasing of duck meat among consumers, the demand for growth performance and the meat quality health of ducks in increasing. Dietary curcumin altered the growth performance and meat quality. However, study on the effect of dietary curcumin on the growth performance, serum antioxidation and meat quality of ducks. This study invested effects of dietary curcumin given to ducks on the growth performance, antioxidation capacity in plasma, meat quality, lipid oxidation and the concentration of volatile compounds in duck breast muscle. A total of 600 healthy ducks with similar body weight were randomly allotted into 4 groups with 10 replicates per group and 15 ducks per replicate. Ducks were fed experimental diets which the curcumin supplemental levels were 0, 300, 400 and 500 mg curcumin/kg basic fed, respectively. The experiment lasted for 10 weeks. Results: Results showed that dietary supplementation of curcumin at levels 300, 400 and 500 mg/kg dietary (P < 0.05) improved the average final body weight. The ducks fed the basal diet without curcumin supplementation had the lowest FI (P > 0.05) and highest FCR (P > 0.05) among all ducks. Feeding ducks on diets supplemented with curcumin at each level significantly increased (P < 0.05) plasma activity of T-SOD and GSH-Px, and significantly reduced plasma MDA concentration compared to the control group. The dietary curcumin significantly increased the growth performance and the antioxidation capacity in plasma of ducks. Dietary curcumin improved the meat quality of ducks by significantly increasing pH45, pH24 (P < 0.05) and color of duck meat (P < 0.05), and significantly decreasing cooking loss (P < 0.05), shear force (P < 0.05), and the lipid oxidation of duck meat. 56 volatile compounds were identified and quantified. Interestingly, cantharidin among volatile compounds was firstly found in duck muscle, and only existed in the group of 500 mg curcumin/kg diet. Conclusions: In conclusion, the supplementation of duck diets with curcumin at 300, 400, and 500 mg/kg diet improved growth performance, antioxidant status and meat quality of ducks. The cantharidin was firstly found in duck breast muscle when the dietary curcumin inclusion of 500 mg/kg.
