The experiment was to study the effect of different content of raspberry tea on growth performance, slaughter performance, blood indexes of Wenchang broilers. 240 healthy Wenchang broilers of 70-day-old with similar body weight were randomly divided into four groups with five replicates in each group and 12 broilers in each replicate. The broilers in control group were fed with basic diet, and the broilers in experimental group were fed with different levels (0.2%, 0.4%, 0.6%) of raspberry tea in basic diet. The experiment lasted for 54 d. The results showed that compared with the control group, the final weight and average daily gain of the 0.4% raspberry tea group were significantly increased (P<0.05), and the feed to gain ratio was significantly decreased (P<0.05). Compared with the control group, the breast muscle rate of 0.4% raspberry tea group was significantly increased (P<0.05), and the slaughter rate and breast muscle rate of 0.6% raspberry tea group were significantly increased (P<0.05). The serum total antioxidant capacity (T-AOC) and total superoxide dismutase (T-SOD) activity of Wenchang broilers were significantly increased in 0.4% raspberry tea group (P<0.05). Compared with the control group, dietary supplementation of 0.2%, 0.4% and 0.6% raspberry tea could significantly increase the serum IgA content of broilers (P<0.05). The experiment indicates that adding raspberry tea to the diet can improve the growth performance, slaughter performance, serum antioxidant capacity and immune function of Wenchang broilers, and the best level is 0.4%.

Reactions of H3tda (H3tda = 1H-1, 2, 3-triazole-4, 5-dicarboxylic acid) with Sm(NO3)3 ·6H2O, Eu(NO3)3 ·6H2O, and Tb(NO3)3 ·6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [ Ln2(tda)2(H2O)3] ·5H2O [ Ln = Sm ( 1), Eu ( 2), Tb ( 3)]. These compounds were structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), PXRD and single-crystal X-ray diffraction. The single-crystal X-ray diffraction studies of compounds 1- 3 reveal that all compounds are three-dimensional porous structures with chiral frameworks. Furthermore, the luminescence studies of compound 2 and 3 in the solid state reveal that they are potential luminescent materials at room temperature. [ABSTRACT FROM AUTHOR]
