  The effect of the dopants of Cr and V on the optoelectronic properties of AZO thin film by pulsed DC magnetron sputtering has been investigated. We also use HCl and KOH solutions to conduct the chemical stability of AZO:Cr:V thin film. The experimental results show that the optimum AZO optoelectronic properties without Cr and V doping obtain the resistivity of 9.87×10−4Ωcm, optical transmittance of 84% and surface roughness rms value of 2.6nm. The chemical stability of AZO will increase after Cr and V doping. Under the added V=0.19wt.%, Cr=0.56wt.%, AZO:Cr:V thin film showed 52% increased chemical stability and 128% decrease in surface roughness after etching (the resistivity was 3.62×10−3Ωcm and optical transmittance 81%). From the experimental results, the higher resistivity obtained after KOH etching compared with after HCl etching. The reason is that the Zn/Al ratio will reduce after etching and cause the AZO film carrier density to reduce as well. However, the optical transmittance obtained after KOH etching will be higher than that after HCl etching. This is because that a better surface roughness after KOH etching obtained than after HCl etching.

  The pork industry is dedicating to provide fast-growing pigs with high-grade meat; this study aimed to explore the relationship between dietary energy and growth output. Thirty two individually-penned male Lantang pigs (initially weighed 20.21±0.63 kg) were randomly assigned to one of four dietary treatments, with 4 replicates of 2 pigs each. The Digestive Energy (DE) of T (treatment) 1~4 were 9.24, 11.02, 12.66 and 14.29 MJ kg-1 feed, respectively. Feeding trail was terminated when all pigs within a treatment averaged 60±2 kg b.wt. and all pigs were slaughtered. The feeding time to reach terminal b.wt. were longer in both T1 and T2 in contrast with T3 and T4 (p<0.01). Average daily energy intake increased linearly with dietary energy concentration (p<0.01). Compared with the other three groups, average daily gain (p<0.05) and feed to gain ratio (p<0.05) of T4 were significantly increased and decreased, respectively. Relative contents of major white fat and perinephric fat, as well as adipocyte size of T4 were higher than those of the other groups (p<0.05). These results indicated that increasing dietary energy content improved fat accumulation in Lantang growing pigs possibly through direct deposition of fat in adipocyte. Higher content of dietary energy tend to increase growth rate of the pig, yet the over-deposition of body fat as well as its possible impact on carcass quality and marketing profit need to be further explored.

  Objective: Manganese (Mn) is a crucial trace element for poultry nutrition because it has multiple physiological functions. Thus, the main goal of this study was to evaluate the effects of dietary Mn supplementation on laying performance, egg quality and antioxidant status in Shanma laying ducks. Methodology: Five hundred and four Shanma laying ducks, at 17 weeks of age, were randomly assigned to 7 treatments, with 6 replicates per treatment and 12 ducks per replicate. Birds were fed the same basal diet, which was supplemented with 0.0 (control), 15, 30, 45, 60, 75 or 90 mg Mn/kg in the form of Mn-sulfate. Results: Results showed that dietary Mn supplementation did not affect egg production, egg weight, feed conversion ratio, egg mass, egg quality, tibia characteristics, total antioxidant capacity, copper-zinc superoxide dismutase or lipid peroxidation (malondialdehyde), but supplementing 90 mg Mn/kg diet significantly (p<0.05) improved the activities of total superoxide dismutase, Mn-containing superoxide dismutase and increased Mn content in egg yolk compared with the control group. Conclusion: These results indicate that corn-soybean meal diet containing sufficient amount of Mn for laying performance and egg quality in Shanma laying ducks under the conditions of current experiment, but adding 90 mg Mn/kg basal diet is required to improve the activities of Mn-containing superoxide dismutase and total superoxide dismutase and elevate Mn content in their egg yolk.

  To investigate the influence of selenium on hepatic antioxidant capacity in ducklings administrated with Afatoxin B1 (AFB1), ninety 7 days old ducklings were randomly divided into three groups (groups I-III). Group I was used as a blank control. Group II was administered with AFB1 (0.1 mg kg-1 body weight). Group III was administered with AFB1 (0.1 mg kg-1 body weight) plus selenium (sodium selenite, 1 mg kg-1 body weight). All treatments were given once daily for 21 days. The results showed that the activity of hepatic Superoxide Dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GSH-Px) and Glutathione Reductase (GR) in group II ducklings significantly decreased when compared with group I (p<0.01). Furthermore, the content of hepatic Malondialdehyde (MDA) significantly increased (p<0.01). However, the activities of hepatic SOD, CAT, GSH-Px and GR in group III ducklings significantly increased when compared with group II (p<0.05). In addition, the content of hepatic MDA significantly decreased (p<0.01). These results revealed that AFB1 significantly induced hepatic antioxidant function dysfunction. However, selenium could significantly alleviat the negative effect induced by AFB1.

  This study proposes a deformation model to elucidate the deformation behaviors of buck materials during various stages of nano-indentation processes. The deformation model presented in this work can be employed to explain the variation of nanohardness with loading conditions, and to elucidate the pop-in phenomenon during nano-indentation. The effect of holding time on hardness is also explained. Brittle materials, Si wafer, and a ductile material, Al single crystal, are used as test specimens in nano-indentation. The experimental results demonstrate that the deformation mechanism developed in this investigation can explain the deformation phenomena of such materials on the nano-scale.

  This study was designed to investigate the influences of dietary copper (Cu) on laying performance, egg quality, plasma total cholesterol (TC), high-density lipoprotein cholesterol (HDLC) and low density lipoprotein-cholesterol (LDLC) concentrations in Shanma laying ducks. A total of 504 egg laying ducks aged 17 week were randomly allotted to seven groups (twelve ducks per replicate and six replicates each treatment). The control group was fed a corn-soybean meal diet, whereas the treatment groups were fed corn-soybean meal diets supplemented with 4, 8, 12, 16, 20, or 24 mg Cu-sulfate/kg. Egg production, egg weight, egg mass, feed conversion ratio, broken egg rate, abnormal egg rate, Haugh unit, yolk color, albumen height, eggshell weight, eggshell percent, eggshell breaking strength, eggshell thickness, plasma TC, HDLC and LDLC concentrations did not appear response to dietary Cu levels. Our results indicated that corn-soybean meal diet containing sufficient amount of Cu for laying performance and egg quality in laying ducks under the conditions of current experiment. Also, laying performance, plasma TC, HDLC, LDLC concentrations and egg quality were not sensitive traits to low levels of Cu.
