Lipid microspheres of different waxes containing urea enriched with a sulfur source for slow release in the rumen

The objective of this study was to obtain and characterize slow-release urea microspheres (SRU) from carnauba wax (CW) and beeswax (BW) with and without enrichment of sulfur source (S). In the 1st experimental stage, we obtained and characterized slow-release urea (SRU) microspheres with a fixed rat...

Zusammenfassung:The objective of this study was to obtain and characterize slow-release urea microspheres (SRU) from carnauba wax (CW) and beeswax (BW) with and without enrichment of sulfur source (S). In the 1st experimental stage, we obtained and characterized slow-release urea (SRU) microspheres with a fixed ratio of 2:1(wax:urea), enriched or not of sulfur (magnesium sulfate heptahydrate) from the emulsification/lyophilization technique using urea as core into carnauba wax matrix added (CWUS) or not (CWU) of S source, and urea into beeswax matrix added (BWUS) or not (BWU) of S source. All formulated microencapsulated systems showed high yield values, raging 92.9 to 107% for BWU and CWU, respectively, with the highest SRU yields (P
