| 1 | Effects of dietary copper on elemental balance,plasma minerals and serum biochemical parameters of growing-furring male mink(Mustela vison)显示文摘The objectives of this study were to study the effects of different levels of dietary copper on copper and zinc balance, plasma minerals and serum biochemical parameters of mink in the growing-furring periods. One hundred and five standard dark male mink were randomly assigned to seven groups with the following dietary treatments: basal diet with no supplemental Cu(Control); basal diet supplemented with either 6,12, 24, 48, 96, or 192 mg/kg Cu from copper sulfate,respectively. The average daily gain(ADG) linearly(P = 0.0026, P = 0.0006) responded to increasing levels of Cu; maximal growth was seen in the Cu24 group. Feed efficiency tended to improve with the increase of dietary copper level(linear P = 0.0010, quad, P = 0.0011). Fecal copper, urinary copper, retention copper responded in a linear(P < 0.05) fashion with increasing level of Cu. The effect of level of Cu was linear(P < 0.001) for plasma Cu concentration. The serum glutamic-oxalacetic transaminase(GOT) and glutamic-pyruvic transaminase(GPT) activities were increased linearly(P < 0.05) with dose of Cu, but serum total protein(TP) and albumin(ALB) concentrations decreased linearly(P < 0.05) as dietary copper levels increased. Effect of level of Cu was linear(P < 0.001) for serum ceruloplasmin(CER) concentration or Cu-Zn superoxide dismutase(Cu-Zn SOD) activity. Supplemental dose of Cu linearly decreased serum triglyceride(TG)(P = 0.011) and total cholesterol(TC)(P = 0.007). Our results indicated that the activity of Cu-dependent enzymes was enhanced by increasing dietary Cu concentration and that supplementation of Cu in the diet of mink could alter the plasma lipid profile and copper concentration. | Xuezhuang Wu Hu Cui Xiuhua Gao Fuhe Yang | 2015 | Animal Nutrition2015，，1： | 2 |
| 2 | Effects of dry dietary protein on digestibility, nitrogen-balance and growth performance of young male mink显示文摘The experiment was to study the nutrient digestibility and metabolism performance of male minks,which were fed different protein level diets during growth period. Effects of protein quantity on growth and development of minks and feed conversion ratio(FCR) were also investigated. Sixty healthy male minks of 45 d were randomly allocated into six groups with ten replicates, which was one sable for each replicate. The minks in six groups were fed diets in which protein levels were 28, 30,32, 34, 36 and 38%,respectively. The six groups were denoted as P28, P30, P32, P34, P36 and P38. After 2 wk, all minks were weighed, average daily gains(ADG) were calculated, and the digestibility values of nutrients were determined. The results indicated that digestibility of calcium, nitrogen of fence, nitrogen deposition, net protein utilization(NPU), and biological value of protein(BV) were similar(P > 0.05), however, nitrogen intake greatly varied among groups(P < 0.01). Compared with group P28, groups of P34, P36 and P38 showed significant difference(P < 0.01) in ADG and FCR. In conclusion, it was recommended that adding34% protein to mink diet would optimize production parameters including ADG, digestibility of nutrition,and FCR, and negative result was observed when diet protein was lower than 28%. | Tietao Zhang Haihua Zhang Xuezhuang Wu Qiang Guo Zhi Liu Wang Qian Xiuhua Gao Fuhe Yang Guangyu Li | 2015 | Animal Nutrition2015，，2： | 2 |
| 3 | Effects of dietary methionine supplementation on growth performance of cubs,nutrient digestibility, nitrogen metabolism and serum biochemical indicators of female blue foxes(Alopex lagopus)显示文摘The objective of the present study was to investigate the effects of methionine(Met) supplementation on growth performance of cubs, nutrient digestibility, nitrogen metabolism and serum biochemical parameters of female blue foxes. One hundred primiparous female blue foxes that were similar in breeding date, pedigree, age, and weight were selected for the trial. The foxes were randomly assigned to four groups(n = 25 each group) and fed diets supplemented with Met at 2(Met2), 4(Met4), 6(Met6)and 8 g/kg(Met8), respectively, for 40 days. Our data showed that body weights at 20 and 40 d were significantly higher in the Met4 group than in the Met2 group(P < 0.05). The Met4 group also had the highest apparent digestibility of dry matter and crude protein compared with either the Met2, Met6, or Met8 group(P< 0.05). The serum Met and isoleucine(Ile) concentrations were significantly higher in the Met4 group than in the Met6 or Met8 group(P < 0.05). In summary, these data indicate that supplementary Met improves growth performance of cubs likely due to increased crude protein and dry matter and increased nitrogen retention of female blue foxes. The optimal amount of Met supplementation is10 g/kg basal diet. | Jungang Guo Xuezhuang Wu Tietao Zhang Zhi Liu Hu Cui Fuhe Yang Xiuhua Gao | 2015 | Animal Nutrition2015，，4： | 1 |

| 8 | Fuzzy ta/2 symmetries of straight chain conjugate polyene molecules显示文摘On the basis of our recent studies on the molecular fuzzy point group symmetry,we further probe into the more complicated planar one-dimensional fuzzy periodic molecules-straight chain conjugate polyene.Except for the fuzzy translation transformation,the space transformation of the fuzzy screw rotation and the glide plane will be referred to.In addition,other fuzzy point symmetry transformation lain in the space transformation is discussed.Usually there is a correlation between the fuzzy symmetry characterization caused by the transition of the point symmetry elements and by certain space symmetry transformation.For the molecular orbital,the irreducible representation component is analyzed besides the membership function of the fuzzy symmetry transformation.Also,we inquire into the relativity between some molecular property and the fuzzy symmetry characterization. | LI Yun ZHAO XueZhuang XU XiuFang SHANG ZhenFeng ZHOU Zhen CAI ZunSheng WANG GuiChang LI RuiFang | 2009 | Science China Chemistry2009，52，11： | 0 |
| 9 | Reconstructing the state space of chaotic BZ reaction system using power spectrum method显示文摘The BZ reaction in continuous-flow stirred tank reactor (CSTR) is selected, and the chaotic time series in low CSTR flow rates have been achieved. The power spectrum method (PSM) from physics and mathematics is introduced to compute the time delay %T%, the embedded dimension %m% so as to reconstruct the state space of the chaotic BZ reaction system by the time delayed coordinates. Further analysis and characterizations on the reconstructed chaotic attractor show that the results are in agreement with the references. It indicates that PSM is faster, simpler and reliable for processing the chaotic chemical system. | Yongjun Li Zunsheng Cai Yanni Li Dahai Song Hao Song Baomin Xi Keqin Ma Benxiang Wu Xuezhuang Zhao | 1998 | Chinese Science Bulletin1998，43，17： | 0 |
| 10 | Study of the reactivity of radical-molecular addition reaction using density functional theory显示文摘The reactivity of radical-molecular addition reaction was studied in terms of density-functional theory (DFT) and Hartree-Fock theory (HFT). It was found that the DFT method can give more accurate estimated result than the HFT method. The reason might be that the energy of the highest occupied molecular orbital (HOMO) in DFT is not the ionization energy, but rather represents the change in the total energy with respect to the change in occupation number of electrons in the HOMO, consistent with the concept of the transition state. The energy of HOMO in HFT is the ionization energy, which may represent more properly the property of the products and reactants themselves. | WANG Guichang SHANG Zhenfeng YANG Zuoyin PAN Yinming CAI Zunsheng ZHAO Xuezhuang LI Yongwang SUN Yuhan ZHONG Bing | 2001 | Chinese Science Bulletin2001，46，6： | 0 |
