Protein Changes in Fish Meal when fat has been extracted by trichlorethylen by Dr. J. C. de Ruyter de Wildt. Rijkslandbouwproefstation, Hoorn, Holland, 1929.

In the former communication it was shown that when the fat is extracted from fish meal by trichlorethylen, the feeding value of the fish meal has been decreased and we have started the idea that not only the diminution of the fat content has caused this decrease, but perhaps a protein change too.
