Whole cottonseed has been used extensively in dairy cattle diets for many years; however, its use in the beef industry has been comparatively limited, despite its high protein and fat content. Previous research has suggested that whole cottonseed may decrease the shedding of Escherichia coli O157 in cattle (Hancock et al., 1994; Garber et al., 1995). Decreasing the prevalence of this organism a...

Six mature Holstein cows in late lactation and fitted with permanent ruminal, duodenal and ideal cannulae were used in a double 3 X 3 Latin-square design to study the effect of roasting or extruding of cottonseed on protein degradation in the rumen and availability of amino acids in the small intestine. Raw whole cottonseed (CS), extruded whole cottonseed (ECS), and roasted whole cottonseed (RC...

In experiment 1, 24 midlactation, multiparous Holstein cows were used in six 4 x 4 Latin squares to evaluate extruded-expelled cottonseed (EEC) as a source of ruminally undegradable protein (RUP). Diets were formulated to contain: 16% crude protein (CP), 35% RUP (SBM16); 18% CP, 35% RUP (SBM18); 16% CP, 40% RUP using EEC (EC16); and 16% CP, 40% RUP using a fishmeal-blood meal blend (FBM16). Mil...

No other feed ingredient provides the combination of effective fiber, energy, and protein like whole cottonseed (WCS). These characteristics make WCS an attractive ingredient for including in rations fed to lactating dairy cows that require high concentrations of energy and adequate effective fiber. But like most ingredients, the composition of WCS has changed. The 2002 cotton crop was negative...

Several criteria are used for determining the acceptability of whole cottonseed (WCS) for crushing including concentrations of moisture, oil, free fatty acids in the oil (FFA), and ammonia. Whole cottonseed that does not meet the minimum standard is typically sold as a feed ingredient. When tropical storms delay cotton harvest and the moisture remain elevated, concentrations of FFA increase. Fe...

Two experiments were conducted to evaluate dry matter intake (DMI), milk yield, and milk composition from feeding rations that contained different sources of genetically modified whole cottonseed to Argentinean Holstein dairy cows. Twenty-four lactating multiparous Argentinean Holstein dairy cows were used in 2 experiments with a replicated 4 x 4 Latin square design, with cows averaging 565 kg ...
