Methods for Dietary Fiber, Neutral Detergent Fiber, and Nonstarch Polysaccharides in Relation to Animal Nutrition

Abstract Companion animal dietsmay contain up to 50% starch, derived from cereal grains. The amount of resistant starch (RS) in an ingredient depends on the origin and form of the ingredient and on the processing conditions to which the ingredient has been exposed. Extrusion has proven to be a means of optimizing utilization of starch by companion animals. Although the RS fraction of starch typically decreases by extrusion, retrogradation can result in increased concentrations of this fraction. Limited research exists regarding the effects of RS in companion animal nutrition and gastrointestinal health. Existing in vitro and in vivo research indicates that certain RS sources are readily fermented in the large bowel, producing short-chain fatty acids, whereas others are less fermentable, resulting in excellent laxation properties. Feeding dogs a diet high in RS may result in an increase in fecal bulk due to an increased excretion of microbial matter in those cases where RS is highly fermentable, or to indigestibility of the RS source in other cases. RS has a role to play as a potential proxy for dietary fiber, especially for those companion animals fed diets high in protein and fat and devoid of traditional dietary fiber.

Dietary Treatments

Abstract A total of 288 pigs (DNA 600 × 241; initially 50.7 kg) were used in an 86-d experiment to determine the effect of dietary fiber source on finishing pig performance. Thirty-six pens of 4 barrows and 4 gilts/pen (total 8 pigs/pen) were randomly assigned to 1 of 3 dietary treatments. Treatments consisted of a corn-soybean meal control (8.7% neutral detergent fiber, NDF), 20% dried distillers grains (DDGS; 13.6% NDF) or 14.5% sugar beet pulp (SBP; 13.6% NDF). Experimental diets were fed from d 0 to 86 in 3 phases. Diets were balanced to constant NE and SID lysine within phase. Net energy values for ingredients were 2,672 kcal/kg, 2,343 kcal/kg, and 1,734 kcal/kg for corn, DDGS, and SBP, respectively. Overall, there was no evidence for treatment difference in ADG or ADFI. Pigs fed DDGS had a tendency for poorer G:F compared to pigs fed the control or 14.5% SBP diets (P < 0.10). Caloric efficiency of net energy (NE) was poorer (P < 0.10) in pigs fed DDGS compared to those fed control and SBP. There was a tendency for decreased (P < 0.07) hot carcass weight and decreased (P < 0.05) carcass yield in pigs fed DDGS and SBP compared to those fed the control diet. Loin depth tended to decrease (P < 0.10) in pigs fed SBP compared to the control with pigs fed DDGS being intermediate. Therefore, pigs fed DDGS tended to have poorer feed efficiency compared to those fed the control diet or SBP. This can be explained by the overestimation of NE demonstrated by an increase in caloric efficiency. Increasing dietary NDF reduced carcass yield. http://www.conferenceharvester.com/

Ultrasound Assisted

Dietary fiber is one of value added products from cassava pulp, byproduct of cassava starch industry. It could be produced by enzymatic digestion in which the optimal condition was studied. The three independent variables are heating temperature (°C) after adding α-amylase concentration (%v/v) and amyloglucosidase concentration (%v/v) regarding of two responses solid percentage yield and neutral detergent fiber (NDF) in the digested sample. The experimental design was based on central composite design. The highest solid percentage yield and NDF of cassava byproduct could get from enzymatic digestion condition at heating temperature at 90 °C, α-amylase concentration of 0.3 % (v/v), and amyloglucosidase concentration of 0.5 % (v/v). For ultrasound-assisted preparation was investigated at the optimum condition of enzymatic digestion. Ultrasound condition was control power of 140% and a frequency of 40 kHz for 15 min. The ultrasound was applied at pre-treatment condition (before adding α-amylase, PU) collocated with intermediate condition (before adding amyloglucosidase, IU) higher NDF yield than optimal condition at 18.78%. In addition, this ultrasound assisted technique give the highest solid percentage.
