Dairy producers of all sizes are effectively using whole cottonseed (WCS), especially in the diet of the early-lactation cow. WCS can increase milk output and boost butterfat. That's why many producers build their herd's diet around the valuable nutrients of cottonseed. WCS is convenient and does not need to be processed before feeding. Since WCS should be mixed with other components of the dairy cow diet, producers with large herds buy WCS in bulk and add it to their total mixed ration (TMR). Small herd owners ask their feed dealer to include it in their pre-mix. On average, a truckload of cottonseed weighs 23 tons, enough for 100 cows for 100 days.
