“…Although there appeared to be a relationship between degree of olive yolk discoloration and free gossypol intake in some of the studies, several reports Heywang, 1957a;Heywang and Lowe, 1959;Halloran and Cavanagh, 1960;Heywang and Vavich, 1965a;Kemmerer and Heywang, 1965) clearly showed a poor correlation. That "bound" gossypol in cottonseed meal can contribute to yolk discoloration has been suggested by two recent reports (Heywang and Vavich, 1965a;Heywang et al, 1965).…”

“…This procedure was based upon spectrophotometric measurement of the "gossypolcephalin" fraction of egg yolks from hens fed cottonseed meal (Grau et al, 1954;Woronick and Grau, 1955) which Narain et a/., (1958) showed was affected by fish meal, but not soybean meal, in the ration. Although Heywang et al, (1961) and stated that the AGU method is not a satisfactory technique for selecting cottonseed meal to be used in laying hen rations based upon stored egg data, Halloran and Cavanagh (1960) found this a desirable method in choosing cottonseed meal for layers. Halloran (1965) further reported that egg-tested cottonseed meals, meals with tested AGU values of less than 0.30, have been fed successfully at the 5 to 10 per cent level.…”

“…experimentally produced under relatively high pH conditions (Conly et af.. 1955) and the basic principle is being applied to commerical operations (Halloran and Cavanagh, 1960). Other chemical treatments of cottonseed meal designed to reduce or eliminate gossypol have also been carried out on a commercial scale, and the products fed successfully (West, 1955, Day, 1958, but are not currently being practised.…”

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.

Three different refining processes were commercially compared by processing 15,148 metric tons of cottonseed with free fatty acid content varying between 7.1% and 8.9%. All of the seed was prepressed and solvent extracted in the Sanbra plant at Bauru, Brazil. The Ranchers Miscella refining process operating on seed averaging 8.8% F.F.A. yielded more oil of lighter color per ton of seed processed than either of the other processes compared, even though the average F.F.A. of the seed processed during the Ranchers Miscella Refining test averaged 1.7% higher than the seed used in the Sanbra process and 1.1% higher than the average F.F.A. for the seed used in the Low Loss Refining test. In another comparison, screw pressed oil, Modified Soda Ash refined was compared to Ranchers Miscella refining with seed containing about 0.5% F.F.A. The results showed 42% lower refining loss and a color of 3.5 Red Lovibond units less for Ranchers Miscella refined oil than for Modified Soda Ash refined oil. The average cost of converting crude cottonseed oil to prime bleachable summer yellow oil by the miscella refining process described is 20.8Ţ per hundred weight of oil (not including refining loss). These costs include the prorated cost of control laboratory, plant labor and supervision, fuel, power, chemicals, depreciation, taxes and insurance.

Processing for nonruminant feed markets

Processing methods can be controlled to provide a cottonseed meal that is improved nutritionally and substantially free from toxic principles. In so doing, cottonseed meal can be fed beneficially to cattle, poultry, swine, and even trout. It is, therefore, possible to feed cottonseed meal to animals and poultry up to 10% of their dietary levels without harmful effects like minimizing their growth, reducing their bone marrow, harming their spleens, or discoloring their egg yolks. It is, however, necessary to prove to those who might use the meal that the feeding is economically sound and as productive as other meals.
