The seeds of cotton (Gossypium hirsutum) fall among the lesser known oil seeds. Cottonseeds are not normally consumed in their natural state due to their gossypol content, an antinutrient. The effect of processing on the sensory characteristics and chemical composition of cottonseed and its extract was studied by subjecting the cottonseed extract to heat treatment (boiling) and the cottonseed t...

Whole cottonseed (WCS) have become a very popular by-product feed for dairy cattle and for wintering beef cows in the Southern USA. The product is locally available to many producers across the region, and in most years WCS are competitively priced with other feedstuffs. Over time, ruminant nutritionists have recommended that WCS should be fed at about 0.5% of average body weight (BW), or about...

Whole cottonseed (WCS) and soybean meal (SBM) were evaluated as potential supplements for preconditioning beef calves in Florida. Weaned calves were fed 2.78 lb/hd/d as fed of WCS or 1.40 lb/hd/d as fed of SBM for a 42-d preconditioning period. Steer calves fed WCS had lower preconditioning weight gains than steers supplemented with SBM (30.7 lb/ hd vs 40.1lb/hd). An economic evaluation of prec...

Twenty crossbred lactating multiparous cows were used in a 28-day study to compare dry matter intake (DMI), milk yield, milk composition and Bacillus thuringiensis (Bt) protein concentrations in plasma when fed diets containing Bollgard II(®) cottonseed (BGII) or a control non-genetically modified isogenic cottonseed (CON). Bollgard II cottonseed contains the Cry1Ac and Cry2Ab insecticidal prot...

To explore whether or not the gossypol varied in cottonseed by-products affect rumen degradability and fermentation efficiency, an vitro cumulative gas production experiment was applied with mixed microorganism to compare characteristics of whole (WCS, n = 3 samples), meal (CSM, hull (CSH, 2 samples). The five-replicate per sample incubation time continuously lasted for 0.5, 1.5, 3, 6, 12, 24, ...

Abstract Whole cottonseed (WCS) has long been a viable supplement in southern beef production systems, but new cultivars and ginning innovations have renewed interest its use. Ad libitum supplementation of WCS, however, leads to increased fat intake, potentially resulting reduced fiber digestibility. However, gestating lactating cows observed adequate or optimum performance under scenarios as m...

The research objective for production of quality cottonseed that has been a major concern of cottonseed researchers for many years is to: "Identify the genetic variability of cottonseed composition, determine the genetic control of cottonseed traits, and develop preferred cotton· seed quality germplasm; develop an understanding of developmental processes of the plant that leads to improved cott...
