Technical Abstract: Large quantities of whole, fuzzy cottonseed and gin trash which are not needed to meet the demands for cottonseed meal and oil are available for ruminant feeding annually. Whole cottonseed is a palatable and desirable feedstuff for some diets, but its overall use is limited because of physical and chemical characteristics. Starch coating and extrusion may reduce these limitations and encourage its use in range cubes. The extruded cottonseed products can then be used to formulate and produce range cubes for wintering stockers. The cubes, or pellets, will be best cost formulated to meet nutrient specifications and quality standards. We are evaluating three treatments: (1) control (CON), no supplement, (2) Commercial Supplement (COMS), and (3) Starch coated and extruded cotton by-products (SCCP). Commercial supplements and SCCP were fed three times a week at a rate of 1.0 lbs/head/day. We are using 197 British and Continental crossbred steers. Treatments are being evaluated from January to August. Steers that are feeding with the COMS supplement gained 35 lbs/head more than the control, whereas steers fed with SCCP gained 20 lbs/head more than the controls. In contrast, steers fed with the COMS supplement gained 15 lbs/head more than those fed with SCCP. Based on these data, it seems that SCCP can be an option for a supplementation source in West Texas rangelands.
