Coconut water
Copra production yields large amounts of coconut water whose nutritive value is very low when the coconut ripens. However, coconut water released in the environment may become a source of pollution and there have been attempts to use it as a substrate for growing food yeast and bacteria. It is also used as semen extender for artificial insemination (Taffin, 1993; Göhl, 1982).
Methane reduction
Coconut oil is particularly efficient in defaunating the rumen and reducing methane production. Adding copra meal to the diet gives comparable decreases in CH4 to refined coconut oil, but also decreases growth performance which would result in an extended finishing time. This has implications for CH4 emissions and production economics because of a longer animal lifetime (Jordan et al., 2006).
