What does copra meal mean in swine nutrition

Thank you for publishing this discussion. We have a hog farm in Visayas and have been mixing our own feed for 8 months now using copra, rice bran, corn meal, soya meal and additives (salt, limestone, molasses, palm oil, copper sulfate, zinc oxide and packaged vitamin supplements). Your Mar'18 review of copra meal has been invaluable as nutritional information about copra is limited and hard to find. In that publication Tables 1 and 2 have columns for Copra Meal and Copra Expellers. Is one of these columns for mechanical extraction and other for solvent extraction? Have you published any more information about copra or rice for swine feed?
Thank you,
