An experiment was conducted with 24 Arabi lambs to investigate the possibility to increase the utilization of wheat straw by ensiling with urea at rate of 1.5 % as a nitrogen source and to get the advantage of the additional digestion caused by the released ammonia, and molasses at rate of 10 % to encourage the fermentation responsible for silage making. Straw silage (ES) was compared with whea...

This study aims to investigate using different ratios of urea-molasses in silage food vitro fermentation, feed value and quality production feed. After being withered a little, the fodder plant was fragmented into 2–3 cm long pieces. 0, 2 4% molasses 0.5 1% urea were added. The treatment groups UM1 (control), UM2, UM3, UM4, UM5, UM6, UM7, UM8 UM9 supplemented with 1, 1.5, 1.5% 2, 4, res...

Two trials evaluated the effects of level of wet corn gluten feed (WCGF), type of supplemental protein, and supplemental tallow on steer finishing performance. In Trial 1, WCGF was fed at 0, 25 (two diets), or 50% of the dietary DM replacing dry-rolled corn (DRC), molasses, and a portion of the supplement. The DRC control diet and one 25% WCGF diet were supplemented with a combination of protei...

In this research, three faecal sludge sanitizing methods-lactic acid fermentation, urea treatment and lime treatment-were studied for application in emergency situations. These methods were investigated by undertaking small scale field trials with pit latrine sludge in Blantyre, Malawi. Hydrated lime was able to reduce the E. coli count in the sludge to below the detectable limit within 1 h app...

Rhodosporidium toruloides and Tetradesmus obliquus pure mixed cultures were grown on primary brewery wastewater (PBWW), with without supplementation of sugarcane molasses (SCM) urea. R. developed in was not able to grow PBWW, or supplementation, but grew the microalga T. all media. In contrast, develop. Higher biomass productivity (149.3 mg L−1 h−1) obtained for culture using PBWW supplemented ...

We examined whether populations of Drosophila melanogaster could evolve a genetically based tolerance to high levels of toxic compounds (urea or ammonia) added to their larval food medium. We also examined whether tolerance to one compound may impart cross-tolerance to other compounds. Five populations selected for ammonia tolerance (AX), five populations selected for urea tolerance (UX), and f...

The conditions required for production of levo 2,3-butylene glycol by Bacillus polymyxa from citrus molasses were studied. Starter cultures required acclimatization to the substrate prior to inoculation of the fermentation medium. Maximal production of butylene glycol with minimal residual sugar was obtained with a medium consisting of molasses, diluted to 20 degrees Brix, and 0.4% urea. Optima...
