Two experiments were conducted to determine the effect of xylanase (850 U g−1) supplementation of a rye and soybean meal-based diet (exp. 1) and β-glucanase (1086 U g−1) supplementation of a barley- and soybean-meal-based diet (exp. 2) on the progress of protein and starch digestion throughout the small intestine. In each experiment, 12 weanling pigs per treatment were fed the experimental diet for a 10-d period, at the end of which feed intake and weight gain were recorded and samples of digesta were collected from the small intestine, colon and rectum. Xylanase supplementation did not result in any improvement in rate or efficiency of gain, feed intake, starch or protein digestibility (P > 0.05). Digesta viscosity was increased by enzyme supplementation in some sections of the small intestine. β-glucanase supplementation resulted in a significant (P < 0.05) increase in rate of gain and improved protein digestibility in the colon and in the last three-quarters of the small intestine, but had no effect on starch digestibility. In conclusion, β-glucanase supplementation of barley/SBM-based diets for young weanling pigs was of benefit whereas pentosanase supplementation of rye/SBM-based diets was not.

The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.

Abstract Forty pigs [10.7 ± 1.2 kg initial body weight (BW) at 6 wk of age] were used in a 21-d study to evaluate the effects of supplemental xylanase (Hostazym X 100, Huvepharma, Inc., Peachtree City, GA) in nursery diets on digesta viscosity, nutrient digestibility, health of the small intestine, and growth performance when supplemented with corn distillers’ dried grains with solubles (DDGS). Pigs were individually housed and randomly allotted to four treatments in a 2 × 2 factorial arrangement (n = 20/factor, 0% or 30% DDGS and 0 or 1,500 endo-pentosanase unit/kg xylanase as two factors) based on sex and initial BW. Feed intake and BW were recorded weekly. On day 15 of the study, TiO2 in diets (0.3%) was used as an indigestible marker to calculate apparent ileal digestibility (AID). Plasma samples were collected on day 19 to measure tumor necrosis factor-alpha (TNF-α), malondialdehyde, and peptide YY. On day 21, all pigs were euthanized to collect tissues from duodenum, jejunum, and colon to measure morphology, TNF-α, and malondialdehyde concentrations. Distal jejunal digesta were collected to measure viscosity. Ileum digesta were collected to measure AID of nutrients. During the entire period, supplemental xylanase increased (P &lt; 0.05) average daily gain (ADG; 616 to 660 g/d) of nursery pigs, whereas DDGS (0 or 30%) did not affect ADG. On week 3, average daily feed intake (ADFI) was increased (P &lt; 0.05) when fed DDGS (1,141 to 1,267 g/d) and there was an interaction (P &lt; 0.05) between two factors indicating that supplemental xylanase decreased ADFI when DDGS was used in a diet. Use of DDGS increased (P &lt; 0.05) viscosity [1.86 to 2.38 centipoise (cP)], whereas supplemental xylanase reduced (P &lt; 0.05) viscosity (2.27 to 1.96 cP) of jejunal digesta. The AID of dry matter (DM) and gross energy (GE) were improved (P &lt; 0.05) by supplemental xylanase. Plasma TNF-α was decreased (P &lt; 0.05, 108.5 to 69.9 pg/mL) by supplemental xylanase. Use of DDGS reduced (P &lt; 0.05) villus height:crypt depth ratio (1.46 to 1.27), whereas supplemental xylanase increased (P &lt; 0.05) the crypt depth (360 to 404 µm) in duodenum. In conclusion, feeding a diet with 30% DDGS to nursery pigs for 3 wk had no negative effect on growth performance, whereas reduced AID of DM and GE, increased TNF-α level in colon tissue, and reduced the ratio of villus height to crypt depth. Dietary supplementation of xylanase reduced digesta viscosity improving AID of nutrients, reduced inflammatory response, and altered intestinal morphology, collectively improving ADG of nursery pigs regardless of the use of DDGS in a diet.

Nutrient Digestion

An experiment was carried out to examine the effects of supplementing diets for weanling pigs with oligosaccharides and LAC on nutrient digestion and bacterial populations and metabolites in the small intestine. Twelve barrows, weaned at 28 d, were fitted with a simple T-cannula at the distal ileum. The BW of the pigs at weaning and at the conclusion of the experiment were 9.1 and 13.8 kg, respectively. The pigs were fed four diets based on barley, wheat and soybean meal according to a two-period change-over design. The diets were formulated to contain 18% CP. Transgalactosylated oligosaccharides (0.2%), GUO (0.2%) and LAC (1%, 4-O-β-D-galactopyranosyl-D-sorbitol) were included at the expense of corn starch. Supplementation with oligosaccharides or LAC had little effect on the apparent ileal digestibilities of AA and monosaccharides. Supplementation of diets with oligosaccharides or LAC did not affect (P > 0.05) the monosaccharide concentrations in ileal digesta except for galactose which was higher (P < 0.05) in digesta from pigs fed the diet supplemented with LAC. The daily ileal output of monosaccharides, pH, ammonia and VFA concentrations, bacterial populations in ileal digesta and incidence of diarrhea were not affected (P > 0.05). Therefore, the supplementation of diets for weanling pigs (9.1–13.8 kg) with oligosaccharides or LAC at these levels does not affect nutrient digestibilities and bacterial populations in the small intestine.

Three groups, each of five pigs, of initial age 5–6 weeks and initial weight 12 kg, were placed on each of three wheat-soybean-meal-based diets of 18% crude protein content. The diets contained either (a) no antibiotic, (b) 110 mg/kg chlortetracycline hydrochloride, 110 mg/kg sulfamethazine and 55 mg/kg penicillin, or (c) diet (b) minus penicillin. Both antibiotic treatments produced a similar growth response of approximately 12%, which resulted partly from an increased feed intake and partly from an improved efficiency of feed utilization.

Two studies were conducted to determine the effect of wheat source on voluntary feed intake when diets were offered in a wet or dry form. The first experiment was designed to establish if a mould inhibitor was necessary. The second experiment allowed more extensive screening of wheat types to determine if there is a genetic component in wheat that explains the differences observed in exp. 1. Experiment 1 was based on two wheat cultivars [Hard Red Spring (HRS) and Durum]. Each wheat was ground, one portion was used as is, the other pelleted and re-ground. The four wheat sources were included at 80% of a standard bioassay diet (with enzyme) and each diet was fed with or without propionic acid. The eight diets were fed ad libitum as is or with 1.2 g water per gram of feed. The wet diets were prepared daily and all diets were fed to four groups of six male broilers from 1 to 17 d of age. The second experiment utilized three cultivars each of HRS and Durum wheat fed in similar bioassay diets with no pre-pelleting or added mould inhibitor; each diet was fed with or without enzyme. Each of the 12 diets in the second experiment was fed with and without 1.2 g water per gram of feed to six groups of eight male broilers from 1 to 21 d of age. For both experiments, the daily intake of feed, on an air-dried basis, was detennined for each diet and used to calculate feed conversion for the respective feeding periods. Experiment 1 showed no effect of supplementing the wheat-based diets with propionic acid. This same experiment also clearly showed that feed intake was increased with wet feeding and there were significantly greater effects when HRS as compared to Durum wheat was fed. Experiment 2 clearly established that there are distinct differences in voluntary feed intake with wet feeding utilizing HRS as compared to Durum wheat. This experiment indicated that wet feeding mimics enzyme supplementation with regard to lowering digesta viscosity, but it is clearly unique from enzyme supplementation with its large effect on feed intake and growth. These studies support our hypothesis that variability in hydration rate of cereal-based diets may limit intake. Key words: Wheat, wet feeding, enzymes, feed intake, broilers

Fibrous components in canola meal and wheat limit their effective use in diets for weaned pigs. Effects of supplementing a carbohydrase (845 and 327 Units g-1 xylanase and β-glucanase) to a wheat-canola meal diet on growth performance, small intestine nutrient digestibility and digesta viscosity were investigated. Ninety-six weaned pigs (7.2 ± 1.2 kg) had free access to control diet [65% wheat, 25% canola meal; 3.15 Mcal digestible energy (DE) kg-1, 10.6 g digestible lysine kg-1] or control diet supplemented with carbohydrase at three inclusion rates (1, 2, or 4 g kg-1) for 28 d. Four pigs were housed per pen for six pens per diet. On days 19 to 21, six pigs per diet were euthanised to collect small intestine digesta. Carbohydrase increased average daily feed intake (ADFI) and average daily gain (ADG) quadratically (P < 0.01) for days 1 to 28, resulting in 16% higher ADFI and 13% higher ADG for 2 g kg-1 carbohydrase compared to control. Carbohydrase did not affect feed efficiency (P > 0.10). The ADG was positively correlated to ADFI (r = 0.94; P < 0.01), but not to feed efficiency (P > 0.10). Carbohydrase did not affect digestibility of dry matter (DM) and energy (P > 0.10). Carbohydrase at 4 g kg-1 only reduced digesta viscosity 30% in the distal small intestine compared to control (P < 0.05). Carbohydrase supplementation increased ADFI and thereby ADG, but not feed efficiency and nutrient digestibility, suggesting that reduction of dietary fibrous components using carbohydrase may stimulate voluntary feed intake of pigs fed diets limiting in DE.

Opening Up

Reducing foregut digesta viscosity is the primary mode of action of feed enzymes in improving performance in broilers fed wheat and barley based diets (Bedford & Classen, 1991, Graham et al, 1992). In pigs, inclusion of appropriate fibre-degrading enzymes can improve the apparent digestion of nutrients in the small intestine (Graham et al, 1988). This has been attributed to both reduced digesta viscosity and an opening up of the feed cell walls enclosing the nutrients. However, the exact mechanism of this effect is unknown. This trial was designed to investigate the influence of enzyme supplementation on gut parameters in the pig.A total of 40 crossbred pigs were weaned at about 9.5 kg and placed into 5 blocks of 8 individual metabolism cages based on litter origin, sex and liveweight. There were 2 treatment replicates per block. The mash diets were based on barley (751 kg/t), soyabean meal (150 kg/t), fish meal (40 kg/t) and soya oil (20 kg/t), with 1 kg/t chromic oxide as a marker. A hulled, low β-glucan (2.9 % of DM; Arra, Finland) and a naked, high β-glucan (5.3 % of DM; Condor, Canada) barley were used, and diets were fed without or with added /3-glucanase. Pigs were fed for 21 days, then sacrificed. Digesta was collected from the stomach, 4 equal lengths of the small intestine, the caecum and 2 equal sections of the colon plus rectum.

Two growth trials involving a total of 36 individually fed Yorkshire gilts were conducted to compare the value of supplemental protein from soybean meal, raw soybeans, and cooked soybeans for growing pigs. Three metabolism trials were also conducted. Cooked soybeans were prepared by cooking in water for approximately 6 hr. The protein supplements were fed at a level calculated to supply the same amount of supplemental protein daily. Performance of pigs fed soybean meal or cooked soybeans was similar and superior to that of pigs fed raw soybeans as indicated by rate of gain, feed intake, and gain to feed ratio. The higher gross energy of cooked soybeans or raw soybeans did not result in increased digestible or metabolizable energy content of the diet. Protein digestibility and retention was lower for diets containing raw soybeans.
