Effects of a high-rice dietary proportion on the meat quality, acute phase reaction proteins (APRPs) and colonic microbiota and metabolites in goats are rarely reported. This study was designed to investigate the meat quality and metabolism in goats. Sixteen goats were equally divided into two groups and fed a control diet (Con, 55% concentrate) or a high-rice diet (HR, 90% concentrate) for five weeks. We found that the HR diet improved the slaughtering characteristic and meat quality but induced an acute phase reaction and decreased bacterial richness and diversity when compared to the control group. Furthermore, the levels of acetate, propionate and total VFA concentrations were higher in the colonic contents of the HR-fed goats than in those of the control group (p < 0.05). Meanwhile, the HR diet decreased the pH value, lactic acid concentration and increased the activity of amylase and lipopolysaccharide concentration in the colonic contents of goats (p < 0.05). The proportion of Oscillibacter increased while Phocaeicola and Christensenellaceae_R-7_group significantly decreased with the HR diet (p < 0.05). Collectively, the HR diet induced an acute phase reaction and altered the colonic bacterial community, which increases the health risk to growing goats.

SummaryElevated plasma fibrinogen levels are associated with an increased risk for cardiac events. Ticlopidine is a drug that inhibits the ADP-induced aggregation of blood platelets and it also has been described that ticlopidine can decrease the plasma fibrinogen level in patients with vascular diseases. The mechanism of this decrease has not yet been elucidated and therefore mechanisms that are known to affect fibrinogen levels were studied, viz. the acute phase reaction, total fibrin plus fibrinogen degradation (TDP) levels and the polymorphisms of the fibrinogen β-gene.The fibrinogen lowering effect of ticlopidine was studied in 26 healthy volunteers, selected on genotype of the BclI polymorphism of the fibrinogen β-gene, and in 26 patients with stable angina pectoris in a double blind, randomized cross-over study. Functional plasma fibrinogen levels were measured with the Clauss assay. Fibrinogen antigen, C-reactive protein (CRP) and TDP levels were measured using an enzyme immuno assay (EIA).In the healthy volunteers the functional fibrinogen levels had decreased by 0.20 g/l (9%, p = 0.005 using the paired Student t-test) after 4 weeks of 250 mg bid ticlopidine administration, whereas fibrinogen antigen, CRP and TDP levels were not significantly changed. In the stable angina pectoris patients the pre-treatment fibrinogen, CRP and TDP levels were significantly higher than in the volunteer group. After four weeks 250 mg bid ticlopidine administration the functional fibrinogen levels had decreased by 0.38 g/l (11%, p < 0.005), whereas the fibrinogen antigen, CRP and TDP levels were not significantly changed. The levels of functional and antigen fibrinogen, CRP and TDP did not change significantly during the placebo period in the volunteers or the patients. Neither in the volunteers nor in the patients was the effect of ticlopidine on the fibrinogen levels associated with the fibrinogen β-gene polymorphisms.Therefore, the fibrinogen lowering effect of ticlopidine is likely to be a modulation of the functionality of the molecule and unlikely to be modulated by the acute phase reaction, TDP-levels or the fibrinogen β-gene polymorphisms.
