“Hydrogen peroxide is used more and more as the water and wastewater as well as slurry disinfectant. Its advantages over other oxidants are nontoxic, harmless, and environmentally acceptable by products. The basic task in the disinfection of slurry is to destroy or remove infectious microorganisms so that the slurry cannot transmit disease producing agents, when disposed on the land or into waters.
In the present study the effect of hydrogen peroxide disinfectant with catalytic action of metal ions, silver and ferrous, was investigated in the hygienization process of pig and cattle slurry. In order to determine the optimal concentration of disinfectant, the effect of a range of final concentrations of hydrogen peroxide alone and with metal ions was investigated. Organoleptic, physicochemical and bacteriologic parameters were analyzed for wastewater quality assessment in accordance with standard methods.
The results illustrated an improvement of organoleptic properties: color and odor, the oxidation of organic matter across reduction of BOD5 and ammonium content of the treated slurries as well as a decrease of aerobic mesophilic bacteria and total coliform bacteria numbers. This investigation indicated that the disinfection of slurry with the oxidative compounds with hydrogen peroxide basis and catalytic action of silver and ferrous ions can be recommended for its bactericidal and oxidative effect.

Supplementation of calves with stabilized orthosilicic acid .pdf

The bioavailability of silicon in stabilized orthosilicic acid was investigated in a double blind, placebo controlled supplementation study of calves maintained on a normal diet. The total dietary Si intake was increased by 4.9% in the form of stabilized orthosilicic acid. After 23 wk of Si supplementation, the serum Si concentration increased (p=0.0001,n=29) by 70% compared to control animals in spite of the low Si dose administered and the Si adequate diet. The individually administered Si dose was significantly associated with the serum Si concentration (r=0.44,p=0.016,n=29). The collagen concentration in dermis was significantly higher (p=0.019,n=4) in the Si group and a positive correlation (r=0.72,p=0.018,n=9) was found between the Si concentration in serum and the collagen concentration in cartilage. The calcium (Ca) and phosphorus (P) concentrations in serum were marginally higher for animals supplemented with Si compared to control animals. In serum, a significant linear relationship was found between the Si and the Ca concentration (r=0.31,p=0.019,n=59), whereas the magnesium concentration correlated marginally with the Si concentration (r=0.25,p=0.068,n=59). In summary, increasing the total dietary Si intake by 4.9% in the form of stabilized orthosilicic acid resulted in a 70% higher Si concentration in serum indicating a high bioavailability of Si in this supplement. The positive correlation between the serum Si concentration and the collagen concentration in cartilage and the serum Ca concentration, respectively, suggest the involvement of Si both in the formation of extracellular matrix components and in Ca metabolism.
