Abstract
The bulk of the experimental evidence suggests that solvent and press-extracted soybean oil meals have a similar value as protein supplements for chick growth. Few studies have been reported comparing solvent and press-extracted cottonseed meals. Groschke et al. (1947) have shown that gland-free solvent-extracted cottonseed meal was superior to commercial cottonseed meal for growth in chicks from 2 to 6 weeks of age. Boatner et al. (1948) in an extensive study of cottonseed meal concluded that the pigment glands of the cottonseed kernels contain all of the components injurious to chicks. Their results indicated that components of the glands other than gossypol or gossypurpurin have a deleterious effect on chick growth.In this note the results of some growth trials are reported in which solvent and hydraulic extracted cottonseed meals were compared with solvent soybean oil meal. The percentage of protein in the samples of oil meals was 49.4, 40.0, .
