Not sure what the product you're refering to is. In the subject line was referred to as cotton fiber blend. There is a product that is usually referred to as cotton motes or linters. Motes are the extra short fibers which are removed in the ginning process. Basically they are cotton fiber which is cellulose. Most of the feed value of motes is fiber, which can yield some energy when digested by a ruminant. IMO-Motes would have the value of straw/low quality hay. When supplemented with protein & minerals, would be adequate diet for dry cows. Would need additional energy for lactating cows. A couple pounds of corn daily would probably be enough energy for cows in good BCS. More corn if already thin. If this product contains some cottonseed then the feed value will be greater. Ask the seller about feed value analysis of this product. Important parts are %TDN (total digestible nutreints/energy), % protein, % fiber & % ash(dirt). These nutrient values are what determine the feed value of this product.
As far as number of barrels per ton, whole cottonseed weighs approx. 4lb/gal., whereas bulk cotton fiber would probably weigh 1/2 that of cottonseed. The actual weight/gallon of this product would some indicator of the feed value of the product. The heavier the better, unless the extra weight is from dirt (%ash), as some cotton gin byproducts have some dirt in them. The seller should have idea as to the weight per bushel or cubic ft. BTW- if memory serves me correctly 7.5 gallon = 1 cu/ft 1.25 cu/ft = 1 bushel.
Not sure if this is any help. Just my 2 cents worth.
