Much of the copra-cake that is shipped from the Orient is more or less seriously infested with insects, the most important of which is the cigarette beetle, Lasioderma serricorne Fab.

Feeding experiments showed that dairy cows would eat the cocoanut meal made from infested copra-cakes as readily as that made from uninfested cakes and that there was no difference in the amount of milk produced, nor the total solids, butter fat or proteins, when the cows were fed on the infested instead of the uninfested cocoanut meal.

Chemical analysis showed that there was no difference in the meal highly infested with insects and that uninfested, as regards moisture, proteins, fats or acidity.
