Results showed that phytase supplement decreased F/W by 12.4%-13.4%and increased phosphorus availability by 7.63%-8.27%, both of which were significantly superior to the control group (P< 0.05).展开更多

Seventy-two 42-day-old AA broilers were randomly divided into nine treatments, each treatment consisted of four replicate cages of two chickens each. Broilers were fed the following diets： A） CTR： control diet （without any SB and antibiotics）; B） Antibiotic： supply antibiotics （Zinc Bacitracin 40 mg/kg ＋ Colistin Sulfate 8 rng/kg） into the basal diet; C） PSB-100： control diet ＋ 100 mg/kg PSB （powder Sodium Butyrate）; D） PSB-200： control diet ＋ 200 mg/kg PSB; E） PSB-300： control diet ＋ 300 mg/kg PSB; F） CSB-100： control diet ＋ 100 mg/kg CSB （coated Sodium Butyrate）; G） CSB-200： control diet ＋ 200 mg/kg CSB; H） CSB-300： control diet ＋ 300 mg/kg CSB. The birds were housed in 36 wire cages in an environmentally controlled room, fed for ad libitum intake and had free access to water. Feed and excreta samples were collected to determine DM （dry matter）, CP （crude protein）, EE （ether extract）, GE （gross energy） and NDF （neutral detergent fibre）. Results in- dicated that compared with control diet, SB could improve the AMR （apparent metabolic rate） and TMR （true metabolic rate） ofDM, CP, EE, GE and NDF on broilers, and it could replace antibiotics partly, and the effect of CSB was better than that of powder （uncoated） ones.展开更多

METHODS: Tyrosinase activity was estimated by measuring the oxidation rate of L-dopa. Inhibition of the enzyme was deduced according to the Lineweaver-Burk plots compared to the control. RESULTS: Cadabine, paeonal, farrerol, evodin, cinnamic acid, aloin and sophorcarpidine had different levels of inhibition of tyrosinase. The inhibitory rates of cinnamic acid (2 mmol/L, 0.5 mmol/L), aloin (2 mmol/L) and the rest were significantly higher than that of hydroquinone (0.5 mmol/L) (P展开更多

Methods： A total of 30 gymnasts were randomized into two groups. After intensive physical training, 15 cases in the treatment group were treated by mild moxibustion and cupping, whereas the other 15 cases in the control group took a 30-rain break. After that, the Creatine Kinase （CK）, Blood Urea Nitrogen （BUN）, routine urinalysis, Rating of Perceived Exertion （RPE） and changes in Self-report Symptom Checklist 90 （SCL-90） were observed before and after one and periodic exercises. Results： After intensive physical training, athletes in the treatment group obtained a faster recovery of elevated CK levels than those in the control group. Analysis on the SCL-90 has shown that athletes in the treatment group had better interpersonal relations than those in the control group. Additionally, RPE analysis has also indicated that athletes in the treatment group had milder fatigue than those in the control group. Conclusion： Combined moxibustion with cupping is an effective and easy-to-operate method for exercise-induced fatigue.展开更多
