Effect of Heat-treatment on Ruminal Protein Degradability of Wolffia Meal (Wolffia globosa L. Wimm)

Anut Chantiratikul and Songsak Chumpawadee

The objective of this research was to reduce ruminal protein degradability of Wolffia meal (Wolffia globosa L. Wimm.) by roasting at 150°C for 2 to 8 min. Two Thai-indigenous x Brahman crossbred cattle were used to determine the in situ ruminal degradability of heat-treated Wolffia meal. The ruminal degradation characteristics of Wolffia meal were determined using nylon bags incubated in rumen in reverse order for 72, 48, 24, 12, 8, 4 and 2 h. The results found the decreased rapidly soluble Crude Protein (CP) fraction (p<0.05) and the increased potentially degraded CP fraction (p<0.05) of Wolffia meal roasted at 150°C for 6 to 8 min. However, protein degradability of Wolffia meal was not reduced by heat treatment. The results indicated that roasting at 150°C for 6 to 8 min could not protect Wolffia meal’s protein degradation by rumen microorganism.
