Because of the more complete extraction of the oil, new-process meal contains more protein than does old-process. Because of the lower digestibility of new-process meal, a given weight of this feed contains somewhat less digestible protein than does old-process meal. Old-process meal is poorer in carbohy- drates but considerably richer in oil than new-process. At the Iowa Station, i Wilson and E«ed, testing the relative merits of the two meals with fattening cattle, found that new-pro- cess gave equally as good returns as old-process meal when fed in connection with other fodders. 205. Value of oil in oii cake.— Eussian flax-seed oil cake carries more oil than does American. To decide the merits of oil cake con- taining much or little oil, tests were conducted in England by Cooke' under direction of the Norfolk Chamber of Agriculture, with Sir John B. Lawes and Dr. Voelcker as counselors. Sixty sheep were divided into two lots of thirty each; to the first lot was given cake containing six to seven per cent, oil, while the second lot received cake containing from fifteen to sixteen per cent, oil. The by-fodders were the same with both lots. Results of feeding linseed cake, low in oil and rich in oU, to sheep — CooJce, Norfolk, England. High-oil cake.
