Boatner et al.
(I948) demonstrated that all of the physiologically deleterious components
of cottonseed are segregated in the pigment glands which constitute approximately
~-4% of the cottonseed kernel. It was found that feeding pigment
glands to chicks at a level of o.65% of a soybean diet resulted in depressed
growth, reduced food efficiency and a lowered percent of livability. Even
though feeding pure gossypol did result in significantly inferior growth, the
deleterious affect produced by either the raw meal or pigment glands was
much greater than that of gossypol alone. Eagle (2948) repeated these obser,
vations with rats, mice, guinea pigs and rabbits.
