Abstract:
Background and Objectives: The growth of the ethanol industry has increased the need for alternatives to corn in lactating cow diets. Glycerol has the potential to replace corn in the diet. Due to high potential fermentation of glycerol in the rumen, the study aimed to investigate the efficiency of encapsulation and nano-dispersed techniques to protect glycerol from ruminal degradation and fermentation. Materials and Methods: The current study was carried out using batch culture technique using 9 treatments as follow: Control diet (50% concentrate: 50% roughage), G20: replacing 20% of corn in control diet with glycerol, G30: replacing 30% of corn in control diet with glycerol, G40: replacing 40% of corn in control diet with glycerol, B20: replacing 20% of corn in control diet with glycerol encapsulated beads, B30: replacing 30% of corn in control diet with glycerol encapsulated beads, B40: replacing 40% of corn in control diet with glycerol encapsulated beads, N20: replacing 20% of corn in control diet with nano-dispersed glycerol solution, N30: replacing 30% of corn in control diet with nano-dispersed glycerol solution and N40: replacing 40% of corn in control diet with nano-dispersed glycerol solution. Results: The results showed a negative effect of using crude glycerol and encapsulated glycerol beads on ruminal digestibility and pH, while using nano-dispersed solution were similar to control diet. Conclusion: It could be concluded that the nano-dispersed glycerol solution might be more effective under rumen condition and fermentation.
