CHEMICAL NEWS, Į Jan. 19 1917 Report on Cattle Feeding Experiments. 25 Summary Results with young Store Cattle.-Better average gains were given by those wintered inside than than those wintered outside, but at the end of March practical valuers attached 30s. a head more value to those wintered outside, as they had better coats of hair and were more promising grazing cattle. Palm kernel meal gave better results than palm kernel cake with these young cattle, although the meal contained less than 2 per cent of oil and the cake nearly 6 per cent. The gains per week were quite satisfactory for such store cattle in winter, and each lot came through the winter well. (See Table III.). Summary Results with Fattening Hoggs.-The sheep used were three-parts bred hoggs, and had been bred near Rothbury in 1915. All the lots made satisfactory gains, which indicated that palm kernel cake and palm kernel meal are suitable foods for fattening sheep. Again palm kernel meal gave a better result than palm kernel cake. (See Table IV.). The fattening bullocks made average net gains of from £3 to £6 a head; their live weight value increased from 475. to 62s. a cwt. during the fattening period. The fattening heifers made average net gains of 50s. to 64s. a head. The net gains per head for the stirks varied from Ios. to 238., and their value as stores increased from 42s. 6d. a cwt. at the beginning of the winter to 48s. at the end. The fattening hoggs made net gains per head of from 39. to 55., and improved in live weight value from 51. to 6 d. a lb. during the fattening period. The Chairman of the Colonial Office Committee on Edible and Oil Producing Nuts and Seeds (Mr. A. D. Steel Maitland, M.P., Under Secretary of State for the Colonies) wrote on August 14, 1915, that his Committee would be very glad if the experiments now completed at Cockle Park, as well as other trials at Offerton Hall and COMPOSITION OF THE FOODS USED IN THE TRIALS. By S. H. COLLINS, M.Sc., F.I.C., Lecturer and Adviser in Agricultural Chemistry, Armstrong College. taken by the cattle and sheep in the dry state, but this was not so. The results are of a satisfactory character, and show that each of the new foods are valuable additions to our feeding stuffs. Care was taken that if any animal left any of the cake or meal this was removed. This is an important precaution in introducing any new foods. The cakes and meal were kept in the granary, and were in quite good condition after being stored for some months. In some previous trials palm kernel cake gave the cattle more glossy coats and more "bloom," but in these trials no such effect was produced on the fattening cattle or on the young stirks. at Newton Rigg, could be proceeded with, and also if the results might be reported to his Committee when the trials had been completed. Sir Owen Philipps, K.C.M.G., M.P., a member of the Oil Producing Nuts Committee, has taken great interest in the progress of these trials and presented to the Cockle Park Committee 4 tons of palm kernel cake (from the African Oil Mills Co., Ltd., Liverpool) and 2 tons palm kernel meal (from the Premier Oil Extracting Co., Ltd., Stone ferry, Hull) for these trials. In 1913 over 234,000 tons of palm kernels were exported from British West Africa, of which over 181,000 tons went to Germany and about 40,000 tons to this country; and in 1912 over 50,000 tons of the same were exported from French West Africa, o which about 43,000 toos went to TABLE 1.-Feeding Experiments with Cattle Eighteen to Twenty-four Months Old, 1915-16.
