Profiles of energy metabolites and haptoglobin (Hp) in dairy cows that are transitioned from conventional to organic management in various Alberta farms were compared with those of dairy cows managed conventionally at the University of Alberta dairy farm. Blood samples were collected during the following periods: Dry, 0 - 30, 30 - 60, and 60 - 90 days in milk (DIm, n = 7 cows). Concentrations of metabolites were evaluated by enzymatic colorimetric methods. Concentrations of Hp were determined by bovine ELISA kits. Data were analyzed by the mixed procedures of SAS. Concentrations of NEFA and BHBA in blood were elevated (P mediate 30 to 60, and 60 to 90 d, and lower in the dry period. In addition, BHBA was higher (P mol/L in conventional and organic cows at 0 - 30 d, respectively). Serum concentrations of cholesterol increased with increasing DIm and returned to nadir levels during dry period and was higher (P mediate 30 to 60 and 60 to 90 d, and peaked during the dry period (P m or day × farm type but was higher (P m concentrations of Hp were elevated during dry period;reached peak levels 0 to 30 d and decreased gradually with increasing days postpartum and were much higher at all periods in conventional than organic cows. Overall, concentrations of Hp were 528.1 ± 45.2 μg/mL in conventional cows vs. 261.1 ± 16.9 μg/mL in organic cows (P metabolic changes associated with initiation of lactation are preceded by an acute phase response in dairy cows, and that cows in organic systems seem to be healthier than cows under conventional sy

Jaalwala Distributary was selected to see the consequences of concrete lining on the underlying saline groundwater table. Its middle and tail portions were concrete lined whereas the head portion was still unlined. Visual mODFLOW 2011.1 was used to simulate the effects of concrete lining on saline groundwater in two-dimensional format. Simulation results showed a gradual rise of electrical conductivity (EC) up to 7000 μS/cm and decline in water table depth to nine feet (2.74 m). It observed negligible inflows from the distributary through its western boundary due to formation of a permanent barrier in the way of seepage of any kind. Results have further predicted that freshwater layer available beneath the Jaalwala Distributary (before its lining) will finish ultimately and the below present saline water also move upward to take this vacated place. Hence it was concluded to line the canals of saline water areas from their sides which will not only protect them from erosion but canal water theft as well.

A field study was scheduled to estimate the impact of intercropping of pearl millet with cowpea on forage yield and quality at Agronomy Research Farm, University of Agriculture, Faisalabad. It was done in kharif season 2016. Randomized complete block design was used to conduct this experiment. It has three replications. The size of net plot is 3.6 m × 6 m. It comprised of five treatments (T1 = one row of millet alternating with one row of cowpea (1m:1C), T2 = two rows of millet alternating with one row of cowpea (2m:1C), T3 = one row of millet alternating with two rows of cowpea (1m:2C), T4 = sole millet, T5 = sole cowpea). We found that intercropping significantly effected the yield and quality of forage. Intercropping system had significant effects on nutritive value of forage crop. Within various treatments of intercropping, it is evident that treatment T2 (two rows of millet alternating with one row of cowpea) gives maximum total dry matter yield (9.68 t ha-1). It was then tracked by treatment T1 (one row of millet alternating with one row of cowpea) and treatment T3 (one row of millet alternating with two rows of cowpea) producing dry matter yield (9.07 t ha-1 and 8.33 t ha-1, respectively). Based on high grain and suitable environmental condition, intercrop productivity compared to sole crop could be selected for improving the productivity of millet/cowpea mixture in the Punjab.

目的基于UHPLC-QTOF-mS/mS技术对骆驼蓬Pegannum harmala化学成分进行分析,并探讨其神经保护活性。方法色谱柱为ACQUITY UPLC BEH C_(18)(100 mm×2.1 mm,1.6μm),流动相为0.1%甲酸水溶液(A)-0.1%甲酸乙腈溶液(B),梯度洗脱;体积流量0.3 mL/min;进样体积2μL;柱温35℃。质谱系统采用电喷雾离子源(ESI),正离子模式下检测。利用过氧化氢(H_(2)O_(2))和6-羟基多巴胺(6-hydroxydopamine,6-OHDA)诱导的PC12细胞氧化损伤模型和脂多糖(lipopolysaccharide,LPS)诱导的BV2细胞神经炎症模型,探讨骆驼蓬全草和种子的甲醇提取物以及去氢骆驼蓬碱、骆驼蓬碱、哈尔满和去甲哈尔满4种骆驼蓬中主要生物碱的神经保护活性。结果从骆驼蓬中共鉴别32个化学成分,全草中主要含有脱氧鸭嘴花碱、鸭嘴花醇等喹唑酮类生物碱,而种子中主要含有去氢骆驼蓬碱、骆驼蓬碱等β-咔啉类生物碱。骆驼蓬全草、种子甲醇提取物和4种生物碱对LPS刺激诱导BV2细胞一氧化氮(NO)生成具有一定的抑制活性,并对H_(2)O_(2)和6-OHDA诱导的PC12细胞损伤均具有明显的保护作用(P<0.01)。结论骆驼蓬全草和种子中的生物碱成分存在差异,而且其所含的生物碱类化合物具有一定的神经保护作用,为骆驼蓬的质量控制及药效物质基础研究提供了参考。

The present study reports the duration of immunity and protective efficacy of Peste des Petits Ruminants(PPR) vaccine(Nigerian strain 75/1) in sheep and goats. A total of 105 sheep and goats were divided into three groups A, B and C. Group A received normal recommended dose(1.0 ml) of PPR vaccine, group B received half dose(0.5 ml) of PPR vaccine and group C was kept as unvaccinated control group in contact with vaccinated animals. The post vaccination dynamics of antibodies against PPR virus was studied. It was found that significant antibody titres persisted for 3 years post vaccination in sheep and goats vaccinated with either full dose or half dose of PPR vaccine. The challenge protection studies were carried out in experimental animals at 24 and 36 month post vaccination. The vaccinates withstood challenge and were found completely resistant clinically and virologically to virulent PPR virus for 24 and 36 months post vaccination. The unvaccinated control animals developed typical clinical signs of PPR and the challenged virus was detected in ocular, nasal and oral secretions of these animals. This study demonstrated that a single immunization with PPR vaccine conferred solid protection in sheep and goats for 3 years.

Nitride-doped ZnO bulk samples were prepared by solid-state reaction method. Structural,magnetic,and optical properties of ZnNOsamples have been studied. The ZnO lattice parameters a and c increase with the increase of the N *** dependence of the lattice constants on N concentration indicates that residual N atoms should be reasonably substituted for 0 atoms in ZnO *** magnetic coercivities of N-doped ZnO samples vary from 60 Oe to 200 Oe,depending on the N concentration,indicating that the films are ferromagnetic at room *** saturation magnetization(m)of the N-doped ZnO films increases remarkably with the N concentration x. Electronic structures of N-doped ZnO were calculated by using the first-principle density-functional theory.A monkhorst-Pack grid with parameters of 3×3×2 was used for irreducible Brillouin zone *** grid of 3×3×2 k points was employed, together with an energy cutoff of 400 eV. Based on the unit cell,3×3×2 supercells of ZnO were constructed,Comparing with the partial DOS of ZnNO,The electronic structure indicates that the energy level splitting is enlarged significantly near the Fermi level for ZnNO-Vsystem. It is may due to the enhancement of coupling between the p orbitals of N and O atoms near the Fermi level.
