“…As the grains used in both experiments were well aged (old season crop) with some weather damage, some effect of germination may have influenced the lack of response to enzyme in the barley diets. Fengler et al (1990) reported that a period of germination of longer than 48 h may attenuate interference to digestive performance by NSP and this may support both the findings of pH effects on enzyme application in the current wheat trial and the suggestion of Bedford and Classen (1993) that in vitro assay of pH sensitive xylanase may be compromised in some circumstances.…”

1. Pelleted diets, incorporating whole or ground wheat or barley in the pellets, were fed to broiler chickens and the performance, gastrointestinal development and digesta characteristics of those chickens recorded. 2. Body weight was similar with whole grain incorporation or enzyme application. Food conversion efficiency was improved by addition of enzyme to a full wheat diet. 3. Whole grain inclusion in pellets reduced proventriculus proportional mass and increased gizzard proportional mass with no apparent effects of exogenous feed enzyme addition. 4. Relative ileal mass was reduced by enzyme inclusion in a wheat diet and by inclusion of whole barley in the pellets. 5. Digesta viscosity was increased by whole wheat inclusion but reduced by enzyme inclusion irrespective of grain processing. Inclusion of 200 g/kg of barley did not alter viscosity of digesta beyond the duodenum. 6. Fresh excreta pH was higher with both cereals in the grower phase when whole grain was fed. On the barley diet, this was affected by enzyme addition, which created higher pH from a point earlier in the grower phase than when no enzyme was employed. 7. Evidence of a complex interaction between higher viscosity and pH being involved in differences in ileal relative mass was found through significant relationships being produced by enzyme use on the wheat diet alone.

“…This action of enzymes can result in improved nutritive value of cereals for poultry (Choct and Hughes 1997) and could also have important consequences for the efficiency of digestion of cereal grain in other species. Some well documented cases demonstrating the importance of endogenous enzymes include large improvements in performance of birds fed germinated (Fengler et al 1990), water-treated (Fernandez et al 1973), or rain-damaged (Choct and Annison 1993) grains. The nutritive values for poultry increased from 10 to 13 MJ/kg dry matter over a 4-month period (Choct and Hughes 1997).…”

Currently, most feed grains are processed by either hammer mill or roller mill before the inclusion in pig diets. However, the effect of these two types of milling and particle size on the performance and feed utilisation has not been adequately examined. The effect of milling processing (hammer mill v. roller mill), particle size, and feeding method (liquid v. dry) was assessed in a factorial design with 120 weaner pigs over 21 days. These pigs had been weaned for 7 days when the experiment commenced. The results revealed that pigs fed on hammer-milled diets had a better performance than those on roller-milled diets. Particle size of hammer-milled diets did not affect the performance of pigs, but influenced the digestible energy content of the diets. However, the feed conversion ratio was poorer for pigs fed coarsely or medium roller-milled diets only at Day 7–14 after weaning. There was a marked advantage in terms of feed efficiency associated with liquid feeding. For pigs offered the hammer-milled diets between 0 and 14 days, simply adding the feed to water improved feed efficiency by some 22%. For the roller-milled diets the corresponding improvement in feed efficiency was 28%. Liquid feeding improved digestible energy (DE) value by 1.5 MJ/kg for medium particle size and depressed DE value by 0.8 MJ/kg for fine particle size for hammer mill. Liquid feeding improved DE values for both medium and fine particle treatments by 0.9 MJ/kg for roller-milled diets. It should be noted that the full advantages of liquid feeding could only be taken if feed wastage from this system can be minimised as much as possible.The study was conducted to investigate if processing method (roller v. hammer mill), particle size (coarse, medium, and fine), and feeding method (liquid v. dry) significantly improved the growth rate, feed intake, and feed conversion of the weaner pig.

“…Svihus et al (1997) reported that performance was very similar in chickens given germinated and enzyme-treated barley, it is likely that the increased nutritional value after germineted was caused mainly by the reduced β-glucan content and viscosity of the barley. Fengler et al (1990) reported that chick performance, as measured by feed to gain (F: G) ratio and apparent retention of dry matter and fat, was greater for chicks fed on diets containing germinated barley. Reduction in β-glucan content and viscosity after germinated demonstrates the effectiveness of endogenous enzymes activated during germinated (Svihus et al, 1997).…”

“…Beside of enzyme supplementation, high moisture storage of barley (Svihus et al 1997), and also germination process of cereal seeds like barley (Celus et al 2006) and oat seeds (Binqiang et al 2010) are effective practical methods for improving its nutritional value and digestibility as well as reducing anti nutritional effects. Fengler et al, (1990) reported that apparent retention of dry matter and fat was greater for chickens fed germinated barley than those fed raw barley. During germination process, the activity of inner enzymes such as β-glucanase increase and transgenic grain containing (1,3-1,4)-β-glucanase can be used as alternative to enzyme additives in barley basal diets (Von Wettstein et al 2000).…”
