Feed ingredients of plant origin are commonly used in swine diets. However, the major components of plant cell walls, non-starch polysaccharides (NSPs), reduce nutrient digestibility. To improve the efficiency of feed utilization, exogenous enzyme products that degrade NSPs have been widely used in commercial animal feeds. Nonetheless, the effects of exogenous enzyme addition to swine diets on ...

The disappearance of dry matter (DM), crude protein (CP), and amino acids (AA) in steers after rumen incubation and intestinal passage of alfalfa hay, barley hay, corn silage, barley grain, corn grain, wheat bran, meat meal, fish meal, cottonseed meal, and soybean meal were measured in 3 steers using a mobile nylon bag technique. Ruminal degradation of individual AA differed between feedstuffs....

Mechanical extraction: this traditional method of cottonseed oil extraction uses a circular mortar (called ghani in India, Achaya, 1993) or more advanced technology, such as a hydraulic press or a screw press (expeller). The cotton seeds may be dehulled, cracked, dried or heated before being fed to the press. The resulting cake is dried, ground and then processed into large pellets (Ash, 1992)....

Chemical composition is critical information for product quality and exploration of new use. Hence defatted cottonseed meals from both glanded (with gossypol) and glandless (without gossypol) cotton seeds were separated into water soluble and insoluble fractions, or water soluble, alkali soluble as well as total protein isolates. The contents of gossypol, total protein and amino acids, fiber an...

Ileal digestibility and availability of lysine in protein concentrates ,for pigs The availability of lysine in protein concentrates for pigs and the relationship between ileal digestibility and availability have been investigated in two separate research projects : Dr Jane Leibholz of the University of Sydney, with weaner pigs, and myself at the Wollongbar Agricultural Institute, using grower p...

One hundred ninety-two steers were fed cottonseed meal, soybean meal or urea supplemented rations in which the corn grain was fed whole (with 5 percent corn silage) or in the high moisture or steam flaked form (with 14 percent corn silage dry matter added). Rates of gain and feed efficiencies were approximately equal for steers fed soybean meal and cottonseed meal and slightly superior to those...

Blood and ruminal samples were analyzed from gestating cows fed apple pomace or corn silage plus isonitrogenous and isocaloric quantities of cottonseed meal or nonprotein nitrogen containing supplements in four trials. Data were also obtained from steers fed similar diets during a metabolism trial. The supplementary sources of nitrogen supplied 50 to 70% of the total nitrogen in the diet. Feedi...

Two experiments were designed to determine the N and AA digestibility of various protein sources (potato protein concentrate, soy protein concentrate, soy protein isolate, linseed meal, sunflower meal, cottonseed meal, canola meal, and camelina meal) fed to growing pigs. In each experiment, barrows were surgically fitted with a simple T-cannula at the distal ileum and fed 4 experimental diets a...
