Soluble and Insoluble Non-Starch Polysaccharides on Digesta Passage Rate and Voluntary Feed Intake of Grower Pigs
نویسندگان
چکیده
The effects of purified non-starch polysaccharide (NSP) fractions (soluble, guar gum (SOL) and insoluble, cellulose (INSOL)) NSP fractions on digesta passage rate, retention time and voluntary feed intake was studied in grower pigs. Compared to control, adding SOL+INSOL increased digesta viscosity, slowed digesta flow rate and increased retention time in the total tract. Voluntary feed intake and daily weight gain reduced with SOL+INSOL NSP, compared to pigs fed the control diet. Reduction in voluntary feed intake associated with feeding high fibrous diet in pigs may be a direct effect of the fibre fractions slowing the flow rate of digesta through the gastrointestinal tract. Thus, reducing the negative effects of soluble and insoluble NSP may enhance feed intake and improve grower pig performance.

Insoluble Fibers Affected the Performance, Carcass Characteristics and Serum Lipid of Broiler Chickens Fed Wheat-Based Diet
The current study was conducted to survey the influences of addition of alfalfa meal (AM), rice bran (RB) and wood shaving (WS) in wheat-based diets [contain soluble non starch polysaccharides (NSP)] on performance carcass characteristic and serum lipids of broilers from 11 to 42 d of age. Seven hundreds 10-d-old male Ross 308 chicks were placed into 35 pens and allocated to seven wheat-soybean...

Thirty-five gilts grown between 18 and 55 kg live weight were used to examine the effects of feeding fermentable carbohydrate on voluntary food intake, performance, carcass characteristics, and large intestinal growth. Five diets were used. The first diet contained steam-flaked sorghum and a supplement based on animal protein sources and 40 g!kg soya-bean meal (diet SAP). Using this diet as a b...

This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in different sections of the gastrointestinal tract (GIT) of broilers fed wheat-based diets. A total of 120 7-day-old Arbor Acres broiler chicks were randomly allotted to two wheat-based experimental diets s...
متن کاملNutritional impact on health and performance in intensively reared rabbits.
The present work summarizes research related to the definition of nutrient recommendations for feeds used in the intensive production of rabbit's meat. Fibre is the main chemical constituent of rabbit diets that typically contain 320 to 360 and 50 to 90 g/kg of insoluble and soluble fibre, respectively. Instead, the dietary contents of cereal grains (~120 to 160 g/kg), fat (15 to 25 g/kg) and p...
متن کاملSoy Oligosaccharides and Soluble Non-starch Polysaccharides: A Review of Digestion, Nutritive and Anti-nutritive Effects in Pigs and Poultry
Soybean contains a high concentration of carbohydrates that consist mainly of non-starch polysaccharides (NSP) and oligosaccharides. The NSP can be divided into insoluble NSP (mainly cellulose) and soluble NSP (composed mainly of pectic polymers, which are partially soluble in water). Monogastric animals do not have the enzymes to hydrolyze these carbohydrates, and thus their digestion occurs b...
