| ABSTRACT This experiment aimed to investigate whether Escherichia coli (E. coli) infection could affect the TGF-β/smads signaling pathway in the jejunal tissue of chickens. One-day-old Cobb 500 broilers were randomly divided into 2 groups and treated with intraperitoneal E. coli or broth injection. Clinical signs of the birds were assessed every day. Spleen and bursa of Fabricius of the birds, post-infection (pi), were collected to evaluate immune organ index. Jejunal tissues were collected to ascertain the expression of TGF-βs, TβRs, and Smads. The results showed that the infected birds had significantly higher index of the spleen (24hrs and 48hrs pi) compared with birds in the control group (p<0.05). The relative gene expression of TGF-β4 increased... |

| ABSTRACT The current study was conducted to develop the correlations between muscle fiber characteristics and meat quality attributes in the biceps femoris muscle of Arbor Acres (AA) and Yellow-feathered chicken (YFC). A total of fourty pure breed birds of AA (n=20) and YFC (n=20) were used in the experiment. After slaughtering at their respective market age of slaughtering: AA 40 d and YFC 120 d, samples were collected for meat quality attributes and myosin ATPase staining for fiber types analyses. Meat quality attributes and muscle fiber characteristics i-e; diameter, cross-sectional area (CSA) and density of AA were significantly different from the YFC (p<0.05). Type I fibers number percentage was significantly higher in YFC than AA, whereas CSA and... |

| ABSTRACT This study has the objective of investigating the effects of traditional Chinese medicine prescriptions (TCM) on serum lipid, abdominal and hepatic fat percentage, cholesterol content in eggs, and mRNA expression of genes apoA I and apoB100. One hundred and thirty five healthy (300-day-old) layers were randomly assigned to three treatments. The hens in control group were fed with the basal diet. The hens in the experimental groups (TCM 1 and TCM 2) were fed with the basal diet supplemented with 1% TCM 1 and 1% TCM 2 respectively over a period of 60 days. Laying performance and the serum parameters relevant to fat metabolism were measured. The results showed that no significant differences were found in average daily feed intake and egg weight... |
