“…The results obtained for the C diet are in agreement with previous studies which showed that the BW of growing animals has no effect on the energy digestibility coefficient for highly digestible diets [9,21]. However, these studies also demonstrated that increased BW of pigs enhanced the energy digestibility coefficient of fibre-rich diets or fibrous ingredients in relation to greater digestibility of the DF fraction in heavier pigs.…”

“…Indeed, pelleting can improve the digestive utilisation of the diet but at variable extents according to the age of the animal [10]. Other processing techniques (grinding) have been shown to be more beneficial to small pigs than to heavier pigs [9]. Accordingly, it can be hypothesised that pelleting improved the digestibility of the diets in growing pigs more than in finishing pigs with a subsequent lower difference in digestibility coefficients between both stages in the present study.…”

-The aim of the experiment was to determine the effect of dietary fibre (DF) level on the digestive and metabolic utilisation of energy in pigs. Two diets were prepared: a control low DF diet (the C diet, 100 g Total Dietary Fibre (TDF)·kg -1 DM) and a fibre-rich diet (200 g TDF·kg -1 DM) which corresponded to a combination of the C diet and maize bran (the MB diet). Each diet was fed as pellets during two successive experimental periods to five, individually caged pigs at growing (42 kg BW) and finishing stages (76 kg BW) for the measurement of digestibility, heat production (HP; indirect calorimetry) and its components. Energy supply was standardised between the diets (2.4 and 2.3 MJ ME·d -1 ·(kg BW) -0.60 for growing and finishing pigs, respectively). The energy digestibility was not affected by growth stage but was lower for the MB diet (83%) than for the C diet (91%). Similarly, the DE value of maize bran (11.5 MJ·kg -1 DM), as calculated by the difference method, was similar at both stages. The fasting HP represented 56% of HP and averaged 0.724 MJ·d -1 ·(kg BW) -0.60 while the physical activity and thermic effect of feed represented on average 14 and 30% of HP, respectively. None of the components of HP was affected by the DF level. The activity HP was greater in finishing (16% of HP) than in growing pigs (12%). Energy cost of standing was constant (kJ·min -1 ) when expressed per kg BW 1.25 . When adjusted for similar ME intake and activity level, total HP and retained energy did not differ between the diets and between the growth stages. In conclusion, the metabolic utilisation of dietary energy was little affected by the DF level in growing and finishing pigs under the conditions of the present study. et un régime enrichi en parois végétales (200 g de fibres totales par kg MS) où une fraction du régime T est remplacée par des drèches de maïs (régime DM). Chaque régime a été distribué successivement à 5 porcs au stade croissance (42 kg PV) et au stade finition (76 kg). Les animaux étaient maintenus individuellement en cage métabolique placée dans une chambre respiratoire afin de mesurer les coefficients d'utilisation digestive de l'énergie et des nutriments ainsi que la production de chaleur totale (calorimétrie indirecte) et ses composantes. Les niveaux alimentaires ont été égalisés à chaque stade (2,4 et 2,3 MJ EM·j -1 ·kg PV -0,60 pour les porcs en croissance et en finition, respectivement). Le coefficient d'utilisation digestive de l'énergie n'était pas différent selon le stade de croissance des animaux ; à chaque stade il était plus faible pour le régime DM (83 %) que pour le régime T (91 %). De la même façon, la valeur ED des drèches de maïs (11,5 MJ·kg -1 MS), déterminée à l'aide du calcul par différence, était comparable aux deux stades. La production de chaleur à jeun (0,724 MJ·j -1 ·kg PV -0,60 ) représentait en moyenne 56 % de la production de chaleur totale tandis que la production de chaleur liée à l'activité physique et l'effet thermique de l'aliment en représentaient 14 et 30 %, r...

“…In the present study, 4% CM or RSM fed in diet to pigs had no negative effects on ADG, ADFI, and G:F, suggesting that inclusion of 4% RSM or CM was not sufficient to impair growth performance of finishing pigs. It is well known that RSM or CM has high fibre content that affects nutrient digestibility (Fernández and Jørgensen 1986;Landero et al 2011). Many researchers have attempted to enhance the nutrient digestibility of RSM through decreasing fibre content and anti-nutritional factors such as glucosinolates by improving processing methods and supplementation of enzymes including carbohydrase (Liu et al 2014;Sanjayan et al 2014).…”

This experiment was conducted to evaluate effects of replacing 'part' of soybean meal (SBM) with 4% rapeseed meal (RSM) or 4% canola meal (CM) on growth performance, nutrient digestibility, blood characteristics, faecal noxious gas emission, and meat quality in finishing pigs. A total of 120 crossbred finishing pigs [(Yorkshire × Landrace)× Duroc] with an average body weight of 50.71 ± 1.97 kg were randomly divided into one of three dietary treatments according to their sex and BW (10 replicate pens with 2 barrows and 2 gilts per pen). Dietary treatments were as follows: (1) CON, a corn-SBMbased diet; (2) CM4, diet containing 4% CM originated from Korea; (3) RSM4, diet containing 4% RSM originated from India. Replacing SBM with 4% RSM or 4% CM had no effects on average daily gain, average daily feed intake, gain to feed ratio, concentrations of blood urea nitrogen and creatinine, faecal ammonia, hydrogen sulphide, and total mercaptans emission, meat quality, and apparent total tract digestibility of dry matter, nitrogen, and gross energy. In conclusion, the inclusion of 4% of RSM or CM in finishing pig diets had no negative effects on growth performance, nutrients digestibility, faecal noxious gas emission, blood characteristics, and meat quality.

“…In general, it is accepted that increasing dietary NSP levels can have negative effects on the digestibility and rate of absorption of nutrients such as starch, protein and fat. In pigs, it was estimated that with each percentage increase of NDF (neutral detergent fiber), energy digestibility could be reduced by 0.4 to 1.8% for fiber from leguminous feeds and 0.9 to 1.0% for fiber from cereals (Fernandez and Jorgensen, 1986). Murray et al (1977) observed that the addition of gelforming (soluble) polysaccharides (methyl cellulose and pectin) to a diet (6% as replacement of starch) caused a decrease in the apparent digestibility of nitrogen at the terminal ileum.…”

: 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 by means of bacterial fermentation. The fermentation of soybean carbohydrates produces short chain fatty acids that can be used as an energy source by animals. The utilization efficiency of the carbohydrates is related to the chemical structure, the level of inclusion in the diet, species and age of the animal. In poultry, soluble NSP can increase digesta viscosity, reduce the digestibility of nutrients and depress growth performance. In growing pigs, these effects, in particular the effect on gut viscosity, are often not so obvious. However, in weaning piglets, it is reported that soy oligosaccharides and soluble NSP can cause detrimental effects on intestinal health. In monogastrics, consideration must be given to the anti-nutritive effect of the NSP on nutrient digestion and absorption on one hand, as well as the potential benefits or detriments of intestinal fermentation products to the host. This mirrors the needs for i) increasing efficiency of utilization of fibrous materials in monogastrics, and ii) the maintenance and improvement of animal health in antibiotic-free production systems, on the other hand. For example, ethanol/water extraction removes the low molecular weight carbohydrate fractions, such as the oligosaccharides and part of the soluble pectins, leaving behind the insoluble fraction of the NSP, which is devoid of anti-nutritive activities. The resultant product is a high quality soy protein concentrate. This paper presents the composition and chemical structures of carbohydrates present in soybeans and discusses their nutritive and anti-nutritive effects on digestion and absorption of nutrients in pigs and poultry.
