The Value of Sunflower-Seed Meal in Rations for Growing-Fattening Pigs1

Abstract

The value of sunflower-seed meal was compared with meat scraps for growing-fattening swine in drylot using the paired-feeding and group-feeding techniques.

In the feeding of nine pairs of young Duroc-Jersey pigs for equal gains, the rations contained 14 percent of crude protein. The protein was derived from yellow corn and alfalfa leaf meal and either 10 percent of meat scraps or 12.5 percent sunflower-seed meal. Each ration contained iodized salt and fortified vitamin A and D oil, and 2.5 percent of steamed bone meal was added to the sunflower-seed meal ration. The feed required for each 100 pounds of gain was 355 pounds and 363 pounds, respectively, in the meat scrap ration and the sunflower-seed meal ration. This difference was shown to be well within the experimental error of the feeding method employed.

In the group-feeding test, three lots of twenty Duroc-Jersey pigs, each averaging about 50 pounds per pig initially, were fed in drylot.

Footnotes

1 The decorticated sunflower-seed meal used in these tests was kindly prepared by the VioBin Corporation of Monticello, Illinois, and donated to the Agricultural Experiment Station by the Corporation and the Piatt County (Illinois) Sunflower Committee. It was prepared by a low-temperature solvent-extraction process, after the hulls were mechanically removed.
