The present study was aimed to investigate the effects of supplemental β-mannanase on in vitro ileal disappearance (IVID) and total tract (IVTTD) dry matter (DM) barley, canola meal, copra corn, corn distillers dried grains with solubles, cottonseed palm kernel soybean wheat for pigs. Feed ingredient samples were finely ground divided into control group treatment group. prepared contain 990 g/k...

In a 4-yr study, molasses (M; 6% CP), molasses-urea (MU; 17.5% CP; 92% molasses, 4% urea and 4% water) and molasses-cottonseed meal-urea (MCSM; 17.5% CP; 73% molasses, 25% cottonseed meal, 1% urea and 1% water) were compared as winter supplements for Braford cows (514 matings) consuming low-quality forage. Cows were fed 1.35, 1.50 and 1.27 kg.head-1.d-1 of the respective supplements for 127 d b...

Water washing of cottonseed meal is more cost-efficient and environmentally friendly than protein isolation by means of alkaline extraction and acidic precipitation. Thus, water-washed cottonseed meal (WCSM) is more promising as biobased wood adhesives. In this work, we examined the effects of the particle size on the morphology and adhesive performance of WCSM. Pilot-scale produced and dried W...

The objectives of this review are to provide 1) information on the FDA Feed Contaminants Program, 2) the legal history of aflatoxins and their current action levels, 3) a report on the levels of aflatoxins, fumonisins, vomitoxin, ochratoxin A, and zearalenone in domestic and import surveillance samples of feed during fiscal years 1989 through 1992, and 4) information on naturally occurring toxi...

One hundred twenty crossbred steers (294 kg, initially) were used in a 141-d finishing trial. Four concentrations (8, 16, 24, and 32% of diet DM) of cottonseed meal (CSM, prepressed solvent-extracted) replaced steam-flaked corn in a corn-based finishing diet. Increasing level of CSM decreased ADG (linear component, P < .10), feed efficiency (linear component, P < .01), and dietary NE (linear co...

The use of high-protein feeds by hvestock feeders to supplement the protein of many common roughages for beef cattle is a general practice based on sound nutrition principles. Protein supplements, as a rule, effect a marked increase in the feed intake of animals on fibrous rations. By providing a better nutrient balance in a ration they increase the efficiency of utilization of the major feed n...
