studies have shown that aflatoxin is immunosuppressive and its ingestion in feed has resulted in decreased immunity in vaccinated birds .therefore, the purpose of the present study was to determine the efficacy of sodium bentonite (sb) and esterified glucomannan (e-gm) of yeast cell wall, in counteracting the toxic effects of aflatoxin (af) on immunization against infectious bursal disease (ibd...

the objective of this study was to evaluate the effects of cottonseed meal (csm) treated with sodium bentonite (sb) on certain blood components and immune response of laying hens. a 3 × 3 factorial arrangement with 3 levels of sb (0, 10, and 20 g/kg of diet) and 3 levels of csm (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. nine mash diets were fed to ...

Although native bismuth is a relatively common mineral, native antimony is less abundant, and Sb-Bi alloys are relatively rare phases in Nature. Sb-Bi alloys and Ag-Cu-Pb-Sb-Bi sulphosalts have been discovered in the Jialong vein-type Cu-Sn deposit in North Guangxi, South China. The Jialong deposit is hosted by schist within the contact zone of a Neoproterozoic granite. Four stages of ore forma...

En el presente artículo se estudia la función dramática de María Josefa dentro estructura La Casa Bernarda Alba. Al concederle papel “loca”, autor convierte en personaje que, a pesar su avanzada edad, rebela contra tiranía hija Bernarda. Así estructurado asemeja las figuras locos y locas presentes teatro español áureo inglés isabelino.

The objective of this study was to compare the effects of soybean (SB) meal (SBM) with increased rumen undegradable protein as roasted SB (RSB), extruded SB (ESB) or their equal blend (RSB + ESB) on production performance, nutrient digestibility, N-utilization efficiency, and blood metabolites in mid-lactation dairy cows. Eight lactating Holstein cows (BW = 534 ± 52 and DIM = 104 ± 5; mean ± SD...

A novel method for prevention of the oxidation of Sb(III) during sample pretreatment, preconcentration of Sb(III) and Sb(V) with nanometer size titanium dioxide (rutile) and speciation analysis of antimony, has been developed. Antimony(III) could be selectively determined by flow injection-hydride generation-atomic absorption spectrometry, coexisting with Sb(V). Trace Sb(III) and Sb(V) were all...

Skutterudites based on CoSb3 have high thermoelectric efficiency, but the low fracture strength is a serious consideration for commercial applications. To understand the origin of the brittleness in CoSb3, we examine the response along various shear and tensile deformations using density functional theory. We find that the Co−Sb bond dominates the ideal strength. Among all the shear and tensile...

The IR and Raman spectra of the compounds (CH,),Sb-Sb(CH,), (I), [(CH,),Si],SbSb[Si(CH,),], (II), [(CH,),Si],As-As[Si(CH,),], (III) and (C,H,),Sb--Sb(C,H,), (IV) have been studied in the liauid and solid states. Given assianments for I to III are based on normal coordinate analyses, and force constants are reported. The solid state Raman spectra of I and II exhibit strong lines near 50 cm-‘, wh...
