“…Nutritional studies completed and published have shown that cottonseed meal experimentally processed from glandless cottonseed has produced good results when fed to chicks (Johnston and Watts, 1964;Hill and Totsuka, 1964) and laying hens Vavich, 1965a, 1965b). The earlier work of Groschke et al, (1947) predicted such a response.…”

“…The amount of heat applied during processing of cottonseed has a considerable effect on protein quality of cottonseed meal. Although uncooked cottonseed or meal is undesirable for chicks (Groschke et al, 1947;Boatner et al, 1948;Johnston, 1961;Johnston and Watts, 1964Hill and Totsuka, 1964) and relatively mild heat treatment of cottonseed protein has been shown to be beneficial (Boatner et al, 1948;Ingram et a/., 1950;Condon et al, 1954;Johnston, 1961 ;Johnston and Watts, 1964), severe heat treatment greatly impairs the nutritive value of cottonseed protein Lyman et al, 1953;Condon et a]., Grau and Zwergart, 1955;Jonsson, 1961 ;Martinez et al, 1961).…”

This review is dedicated to M i . Burt W. Heywang, Superintendent of the Southwest Poultry Experiment Station, Glendale. Arizona. For almost three decades Burt and his associates have enriched the scienific world with a vast amount of data relating to utilization of cottonseed products. This unobtrusive man is admired by all who have known him for his devotion to scientific integrity and thoroughness.

“…A free gossypol content above this figure, however, would not be desirable. Groschke et al (1947) fed gland free cottonseed meal containing 0.007 percent gossypol, as 23 or 35 percent of the ration, and observed olive yolks as well as pink albumen. Bound gossypol (Carruth, 1947) presumably does not influence egg coloration.…”

“…It has two naphthalene rings with identical substituents with restricted rotation about the rings and a molecular formula of C 30 H 30 O 8 . High concentrations of gossypol in poultry diets have been associated with depressed feed intake, feed efficiency, and weight gains and increased mortality (Groschke et al, 1947;Boatner et al, 1948;Lillie and Bird, 1950;Heywang and Bird, 1954;Couch et al, 1955;Heywang et al, 1955;Phelps, 1966). However, Heywang and Bird (1950) reported that increased dietary concentrations of gossypol were not always accompanied by lowered feed efficiency.…”

This study was designed to evaluate the relative toxicity of (+)- and (-)-gossypol enantiomers in 0-3-week-old broilers. Treatments consisted of broiler starter diets formulated with either a glandless, which did not contain gossypol, a commercial glanded [62. 2% (+)-gossypol], or a glanded moco [83.2% (+)-gossypol] crushed cottonseed (CCS) (six replicates/treatment) plus a soybean meal negative control. Glandless cottonseed was mixed with the moco cottonseed (2.4% free gossypol) so that both the commercial glanded and moco glanded cottonseeds contained equivalent concentrations of free gossypol (2.0%). The cottonseed treatments were added at 5 and 10% of the diet. Body weights and feed conversions were determined weekly. Body weights and feed-to-gain ratios of broilers fed 5 and 10% glandless CCS and 5% moco CCS were not significantly different. Broilers receiving 10% commercial glanded CCS weighed significantly less than those subjected to all other treatments. Feed-to-gain ratios were significantly higher for broilers receiving 10% commercial glanded and 10% moco CCS as compared to 5% moco and glandless CCS, 10% glandless CCS, and control. Relative liver weights of birds receiving 10% moco CCS were significantly less than those of birds receiving 10% commercial CCS. The data clearly showed that broilers fed moco CCS containing a relatively high (+)- to (-)-gossypol enantiomer ratio performed better than broilers receiving commercial CCS with a lower (+)- to (-)-gossypol enantiomer ratio.
