Four experiments were conducted to evaluate factors influencing concentrations of plasma total gossypol (TG) in 30 Holstein steers fed cottonseed products. At the end of each 28-d experiment, steers were weighed and blood samples were collected and analyzed for plasma TG concentrations. During the entire study, steers did not show any overt signs of gossypol toxicity. In the 28 d before experiment 1, 30 steers with a body weight (BW) of 273 kg were fed a standardization diet with 15.0% Upland… Expand
Feeding of whole cottonseed on performance, carcass characteristics and intestinal morphology of Zandi lambs
TLDR
The results indicate that the inclusion of 8% WCS in lamb diets could have a positive effect on most of the traits, but increasing the WCS inclusion up to 16% in the diet may have negative effects on lamb performance. Expand
Gossypol disrupts embryo development in heifers.
TLDR
Findings provide in vivo and in vitro evidence that intake of 36.8 mg of FG/kg of BW per d and gossypol concentrations >7 microg/mL in plasma, in uterine flush, or in vitro compromise early embryo development, which might explain some of the negative effects of gOSSypol on the fertility of dairy cows.

Effect of Dietary Supplementation of Ferrous Sulfate on Performance and Carcass Characteristics of Finishing Lambs
TLDR
The hypothesis that the addition of 75 or 150 mg FeSO4 /kg in finishing lamb diets do not impact DMI, growth rate, and carcass characteristics of meat sheep is supported. Expand
Gossypol Intake from Cottonseed Feedstuffs - A Performance Concern for Ruminants?
TLDR
It is possible that feeding excessive amounts of gossypol in the free form may exceed this protective mechanism and impair animal performance, and it is possible the nutrient composition of the two major types of cottonseed differs. Expand
Pharmacokinetic comparison of gossypol isomers in cattle: transfer from diet to plasma and degradation by rumen microbes
A pharmacokinetic comparison of gossypol isomers in cattle was made by investigating their transfer from ingested food to plasma and their degradation by rumen microbes. The gossypol isomers in wholeExpand
Presence of free gossypol in whole cottonseed
TLDR
The Spanish delegation does not differentiate between varieties in their suggestion for an increase in the maximum permitted content of free gossypol for WCS, and the CONTAM Panel considered it not necessary to update the previous opinion. Expand
Effects of over-load iron on nutrient digestibility, haemato-biochemistry, rumen fermentation and bacterial communities in sheep.
TLDR
The results indicate that increasing ferrous sulphate monohydrate in diets had no negative impact on the growth performance, but it changed nutrient digestibility, blood iron parameters, rumen fermentation and bacterial communities in sheep. Expand
Development of an RP-UHPLC-PDA method for quantification of free gossypol in cottonseed cake and fungal-treated cottonseed cake
TLDR
A simple and rapid chromatographic detection method was developed and validated and successfully applied to determine trace levels of free gossypol cottonseed treated with a macrofungus, which is potentially appropriate for use as animal feed. Expand
Case Study: Effect of iron amino acid complex on the performance of lactating dairy cows on a commercial dairy
TLDR
Lactating Holstein cows were used in a randomized design to determine the effect of supplemental iron on milk SCC, milk yield, and milk composition and treatment-by-parity effects were noted for milk yield and yields of milk fat and protein. Expand
SCIENTIFIC OPINION Gossypol as undesirable substance in animal feed 1 Scientific Opinion of the Panel on Contaminants in the Food Chain
SUMMARY Gossypol is a yellow compound produced by the cotton plant that confers resistance to pests. Gossypol exists in two enantiomeric forms, (+) and (-), and is experimentally often used as aExpand

Type of cottonseed and level of gossypol in diets of lactating dairy cows: effects on lactation performance and plasma gossypol.
TLDR
Plasma TG increased linearly with increasing DIM, but cows fed the BUPCP, especially multiparous cows, had a higher increase in plasma TG over time, and yields of milk and milk components were greater in cows with higher plasma TG. Expand
Type of cottonseed and level of gossypol in diets of lactating dairy cows: plasma gossypol, health, and reproductive performance.
TLDR
Consumption of a high gossypol diet for 170 d had no effect on health of lactating dairy cows, but it increased PG concentrations and impaired reproductive performance, and the probability of conception after the first artificial insemination declined at a decreasing rate as the plasma TG increased. Expand
Effects of gossypol from cottonseed on hematological responses and plasma alpha-tocopherol concentration of dairy cows.
TLDR
Erythrocyte osmotic fragility was higher in cows fed WCS, but the increase was attenuated when bST was injected (diet x bST interaction), and no clinical signs of gossypol toxicity were observed in the cows consuming the WCS. Expand
The effects of varying gossypol intake from whole cottonseed and cottonseed meal on lactation and blood parameters in lactating dairy cows.
TLDR
Indicators of liver, kidney, and muscle cell viability suggest that the higher amounts of gossypol consumed in this study had only minor effects on those tissues in lactating dairy cows. Expand
Increasing dietary levels of cracked pima cottonseed increase plasma gossypol but do not influence productive performance of lactating Holstein cows.
TLDR
Although the highest dietary inclusion level of Pima cottonseed numerically depressed performance of cows of both parities, these differences failed to reach statistical significance in these short-term trials with few cows. Expand
Impact of feeding whole Upland cottonseed, with or without cracked Pima cottonseed with increasing addition of iron sulfate, on productivity and plasma gossypol of lactating dairy cattle
Lactating Holstein cows were fed one of four diets containing either whole Upland cottonseed (WCS) or whole Upland cottonseed and cracked Pima cottonseed (CrP) with increasing levels of iron sulfate.Expand
Iron sulfate and feed pelleting to detoxify free gossypol in cottonseed diets for dairy cattle.
TLDR
A follow-up study showed that pelleting reduced free gossypol by as much as 70% in whole cottonseed and by 48% in cottonseed meal, which represents a mechanism to decrease the toxicity of gOSSypol in cotton Seed products. Expand
Effect of whole and expanded-expelled cottonseed on milk yield and blood gossypol.
TLDR
In this experiment, multiparous but not primiparous cows fed whole cottonseed produced more milk than those fed expanded-expelled cottonseed at 14 to 28% of the diet dry matter, however, feed efficiencies were similar for all treatments. Expand
The effects of feeding varying amounts of gossypol from whole cottonseed and cottonseed meal in lactating dairy cows.
TLDR
Increased plasma gossypol concentrations and erythrocyte fragility was higher in the cows receiving the diet E, but it did not differ among other treatments, and dry matter intakes were similar for all groups. Expand
