“…For example, Li et al (1996) and Thacker and Campbell (1999) reported that h-glucanase supplementation increased overall digestibility of dry matter (DM), crude protein (CP) and energy. However, other workers have found no improvement in either performance or digestibility with h-glucanase addition (Graham et al, 1986;Gdala et al, 1997).…”

“…Addition of cell wall degrading enzymes in vitro increased the release of proteins and nonstarch carbohydrate in barley [10] . Supplementation of exogenous NSP enzymes to piglet diets can increase the digestibility of barley and pigs' growth [11][12][13] . This has been attributed mainly to the breakdown of endosperm cell wall components, resulting in more complete digestion of starch and protein in the small intestine.…”

AIM:To investigate effects of non-starch polysaccharides(NSP) enzymes on pancreatic and small intestinal digestive enzyme activities in piglet fed diets containing high amounts of barley. METHODS:Sixty crossbred piglets averaging 13.5 kg were randomly assigned to two treatment groups with three replications (pens) based on sex and mass. Each group was fed on the diet based on barley with or without added NSP enzymes (0.15%) for a 40-d period. At the end of the experiment the pigs were weighed. Three piglets of each group were chosen and slaughtered. Pancreas, digesta from the distal end of the duodenum and jejunal mucosa were collected for determination. Activities of the digestive enzymes trypsin, chymotrypsin, amylase and lipase were determined in the small intestinal sections as well as in homogenates of pancreatic tissue. Maltase, sucrase, lactase and γ-glutamyl transpeptidase (γ-GT) activities were analyzed in jejunal mucosa. RESULTS:Supplementation with NSP enzymes improved growth performance of piglets. It showed that NSP enzymes had no effect on digestive enzyme activities in pancreas, but decreased the activities of proteolytic enzyme, trypsin, amylase and lipase in duodenal contents by 57.56%, 76.08%, 69.03% and 40.22%(P<0.05) compared with control, and increased γ-GT activities in jejunal mucosa by 118.75%(P<0.05). CONCLUSION:Supplementation with NSP enzymes in barley based diets could improve piglets' growth performance, decrease activities of proteolytic enzyme, trypsin, amylase and lipase in duodenal contents and increase γ-GT activities in jejunal mucosa.Li WF, Feng J, Xu ZR, Yang CM.

“…This is a common practice in broiler production (Campbell and Bedford 1992;Chesson 1993); however, studies with swine have yielded inconsistent improvement in digestibility (Aherne and Spicer 1986;Johnson et al 1993;Li et al 1996a) and performance results (Aherne and Spicer 1986;Officer 1995;Liu and Baidoo 1997). Although the differences may be explained as genetic variations among cereals in terms of the content of NSPs, the spectrum of enzymes used, as well as the age of experimental animal, the mechanism of how exogenous enzymes function in the gastrointestinal tract of swine remains unclear.…”

. Effect of microbial enzyme supplementation on energy, amino acid digestibility and performance of pigs fed hulless barley based diets. Can. J. Anim. Sci. 78: 625-631. Two experiments were conducted to investigate the influence of a microbial enzyme preparation on the digestibility and performance of starter-growing pigs fed hulless barley based diets. In the digestibility trial, eight pigs with an average initial body weight of 14 .3 ± 0.4 kg initial liveweight were surgically fitted with steered ileo-cecal valve cannulas at the terminal ileum. Two hulless barley varieties (Condor and CDC Buck) were separately used as the dietary energy source (77.6%) with canola meal as the protein supplement (20%). Enzyme supplementation improved (P < 0.05) the ileal dry matter (DM) digestibility by 15.2%, gross energy (GE) by 11.0% and protein by 7.6%. The average apparent ileal digestibility of the indispensable amino acids was improved by 6.9% (P < 0.05), and of nonstarch polysaccharides (NSP) was improved by 90%. The total-tract digestibility of DM was increased by 6.2%, GE by 6% and crude protein (CP) by 9.4% (P < 0.05). Enzyme supplementation tended to enhance digestion in the small intestine instead of the hind-gut as expected. In the growth performance trial, positive responses from enzyme supplementation were observed from both mash and pelleted diets fed to 48 pigs grown from 9 to 60 kg liveweight. The ADG was improved by 8.6% (P < 0.05) and feed conversion by 8.7% (P = 0.09). Pelleting had no adverse effect on enzyme activity. The results demonstrated that the enzyme supplementation improved (P < 0.5) nutrient utilization and performance of pigs fed diets containing hulless barley. . La préparation enzymatique améliorait (P < 0,05) de 15,2 % la digestibilité iléale de la matière sèche, de 11 % celle de l'énergie brute (EB) et de 7,6 % celle des protéines. La digestibilité iléale apparente moyenne des acides aminés essentiels était améliorée de 6,9 % (P < 0,05) et celle des polysaccharides non amylacés (PNA) de 90 %. La digestibilité totale de la matière sèche augmentait de 6,2 %, celle de EB de 6 % et celle de PB de 9,4 % (P < 0,05). Le complément enzymatique paraissait augmenter la digestion dans l'intestin grêle plutôt que dans le gros intestin contrairement à ce à quoi on se serait attendu. Dans l'essai de performance de croissance, conduit sur 48 porcs élevés à partir du poids de 9 à celui de 60 kg, on relevait des effets positifs de la complémentation enzymatique, indépen-damment de la forme de présentation de l'aliment, pâtée ou granulés. Le GMQ était bonifié de 8,6 % (P < 0,05) et l'indice de conversion de 8,7 % (P = 0,09). L'agglomération de l'aliment n'avait pas d'effet négatif sur l'activité enzymatique. On peut conclure de ces observations que la complémentation enzymatique améliorait significativement les performances de croissance et la valorisation des nutriments chez les porcs exposés à des aliments à base d'orge nue.
