In situ rumen degradation characteristics and bacterial colonization of whole cottonseed, cottonseed hull and cottonseed meal with different gossypol content

Metabolisable Energy, In situ Rumen Degradation and In vitro Fermentation Characteristics of Linted Cottonseed Hulls, Delinted Cottonseed Hulls and Cottonseed Linter Residue

Dietary supplementation with conventional linted cottonseed hulls (LCSH) is a common practice in livestock production all over the world. However, supplementation with mechanically delinted cottonseed hulls (DCSH) and cottonseed linter residue (CLR) is uncommon. Cottonseed by-products, including LCSH, DCSH and CLR, were assessed by chemical analysis, an in situ nylon bag technique, an in vitro ...

Gossypol Toxicity from Cottonseed Products

Gossypol is a phenolic compound produced by pigment glands in cotton stems, leaves, seeds, and flower buds (Gossypium spp.). Cottonseed meal is a by-product of cotton that is used for animal feeding because it is rich in oil and proteins. However, gossypol toxicity limits cottonseed use in animal feed. High concentrations of free gossypol may be responsible for acute clinical signs of gossypol ...

Cottonseed meal | Feedipedia

Mechanical extraction: this traditional method of cottonseed oil extraction uses a circular mortar (called ghani in India, Achaya, 1993) or more advanced technology, such as a hydraulic press or a screw press (expeller). The cotton seeds may be dehulled, cracked, dried or heated before being fed to the press. The resulting cake is dried, ground and then processed into large pellets (Ash, 1992)....

Gossypol, the Toxic Substance in Cottonseed

Since our previous publication (17) on this subject, several articles have appeared in which other explanations of cottonseed-meal poisoning have been offered. Thus, Rommel and Vedder (14) have suggested that poisoning by cottonseed meal is similar to beriberi, and is caused by deficient diets. This view was based on the similarity of post-mortem symptoms noted in pigs fed on rice and tankage. ...
