Acute toxicity of gossypol in northern bobwhites

Relative toxicity of gossypol enantiomers in broilers.

Use of cottonseed meal in poultry diets has been avoided in large part because of fear of gossypol toxicity. Gossypol exists naturally as a mixture of 2 enantiomers that exhibit different biological activities. Two experiments were conducted to determine the relative toxicity of gossypol enantiomers on broilers. In the first experiment, 3-d-old broilers were fed a standard diet containing 0, 10...

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 ...

Toxicity of Gossypol from Cottonseed Cake to Sheep Ovarian Follicles

Gossypol, a polyphenol compound produced by cotton plant, has proven reproductive toxicity, but the effects of gossypol on sheep ovaries are unknown. This study was aimed to determine the in vitro and in vivo effects of gossypol on the ovarian follicles of sheep. This trial was divided into two experiments. In the first one, we used twelve non-pregnant, nulliparous, Santa Inês crossbred ewes, w...

Effect of Acute Toxicity of Cadmium in Mice Kidney Cells

Background: Cadmium is one of the most toxic heavy metals in our environment having a very strong ability to accumulate in body organs, especially in kidney. The present study was done to determine the genotoxicity and cytotoxicity in kidneys of rats exposed to cadmium. Methods: Male rats (n=30), kept in standard conditions were used in this study. The animals were randomly divided into 2 group...
