Group 1 was the control group, fed with basal diet; group 2, group 3 and group 4 were fed with basal diet added with 0.75%, 1.0% and 1.25% astragalus powder, respectively; group 5 and group 6 were separately fed with basal diet added with 1.0% and 1.25% astragalus pow- der, but the astragalus powder was used for 10 d and then was forbidden for 10 d in turn during the whole experiment. The content of triglyceride （TG）, total cholesterol （TCHO）, high-density lipoprotein-Cholesterol （ HDL-C）, and low-density lipoprotein-Cholesterol （LDL-C） were respectively determined when the chickens were 35-day-old and 63-day-old, while the percentage of abdominal fat （PAF） as well as intramuscular fat （IMF） and subcutaneous fat ply （SFP） was measured when the chickens were 63-day-old. [ Result] In 35-day-old chickens, the levels of TCHO were sig- nificantly or very significantly lower in group 3, group 4, and group 6 than in control group （ P 〈0.05 or 0.01 ） ; the levels of LDL-C significantly lower in group 3 and group 6 （ P〈0. 05） ; the level of HDL-C significantly higher in group 5 （P〈0.05）. In 63-day-old chickens, the levels of TCHO and LDL-C were significantly or very significantly lower in group 3, group 4, and group 5 than in control group （ P 〈 0.05 or 0.01 ） while the levels of HDL-C were significantly higher in these groups; the PAF was significantly lower in group 3 （ P 〈 0.05）. [ Condasion] Astragalus powder should re- duce the levels of TG, TCHO and LDL-C, promote HDL-C content, and also play a certain regulative role in deposition of abdominal fat.展开更多

Forty-eight Chinese Holstein bulls((362±12.4) days of age and(483±27.1) kg of body weight(BW)) were assigned to four groups in a completely randomized design with a 2×2 factorial arrangements. Supplemental PFP(0 or 30 g PFP kg-1 dietary dry matter(DM)) and CFA(0 or 120 mg FA d-1 as CFA) were mixed into the top one-third of a total mixed ration. The study included a 20-day adaptation period and followed by a 90-day collection period. The lower(P<0.01) feed conversion ratio with PFP or CFA addition resulted from the constant DM intake and the higher(P<0.05) average daily gain. The higher(P<0.05) ruminal p H, ether extract digestibility, microbial α-amylase activity, Butyrivibrio fibrisolvens copy, and expression of peroxisome-proliferator-activated receptor α(PPARα) and carnitine palmitoyl transferase-1(CPT1), and lower ruminal total volatile fatty acids(VFA) concentration, acetate to propionate ratio, neutral detergent fibre(NDF) digestibility, copies of total protozoa and Ruminococcus flavefaciens, and expression of sterol regulatory element binding protein-1(SREBP1) and acetyl-coenzyme A carboxylase α(ACACA) were observed for PFP addition. Supplementation with CFA increased(P<0.05) ruminal total VFA concentration, acetate to propionate ratio, digestibility of DM, organic matter, crude protein and NDF, activity of cellobiase, pectinase and α-amylase, copies of selected microbial except for total protozoa, as well as expression of PPARα, but decreased(P<0.05) ruminal p H, and expression of SREBP1 and ACACA. The PFP×CFA interaction(P<0.05) was observed for ammonia N, hepatic TG content, and m RNA expression of CPT1 and FAS. There had no significant difference in hepatic TG content when CFA was supplemented in the diet without PFP addition, the lower(P=0.001) hepatic TG content was observed when CFA was supplemented in the diet with PFP addition. The higher(P<0.05) m RNA expression of CPT1, and the lower(P<0.05) m RNA expression of FAS and ammonia N concentration were observed when CFA was supplemented in diet either without or with PFP addition. The results indicated that supplementation of CFA in PFP diet was more effective on increasing hepatic CPT1 expression, and decreasing ammonia N, hepatic TG content and FAS expression than in diet without PFP. Supplementation with PFP or CFA improved growth performance of dairy bulls by promoting nutrient utilization, microbial enzyme activity, microflora, and hepatic gene expression.展开更多
