“…However, ESONU et al (2004), while studying the inclusion of cellulose enzyme in poultry feed over the period of 28 and 35 days of age, saw an increase in feed intake and decrease in weight gain due to the inclusion of the enzyme. Similarly, OPALINSKI et al (2010) found higher feed intake of broilers fed with a diet including an enzymatic complex containing β-mannanase.…”

“…The NSPs have the characteristic of increasing gastrointestinal viscosity, which results in a reduction in the diffusion rate of digestive enzymes and substrates, preventing their interactions on the surface of the intestinal mucosa, leading to impaired digestion and absorption of nutrients. Endogenous enzymes produced by poultry and swine cannot hydrolyze the NSPs contained in cereals (OPALINSKI et al, 2010). In poultry, only the amylase enzyme produced by the pancreas can hydrolyze starch into smaller units that can be absorbed; therefore, the presence of exogenous enzymes is needed (O'NEILL et al, 2014).…”

“…This finding shows that the anti-nutritional effect is not only restricted to altering the digesta flow but also causes disturbances in the normal functioning of the digestive organs, with increased endogenous secretions such as water, proteins, electrolytes, and lipids (Angkanaporn et al, 1994). Monogastric animals including poultry cannot produce or produce insufficient amounts of the specific enzymes necessary to hydrolyze and digest Non-Starch Polysaccharide present in the cell wall of the grains and they remain unhydrolyzed (Opalinski et al, 2010). In poultry, only the amylase enzyme produced by the pancreas can hydrolyze starch into smaller units that can be absorbed; therefore, the presence of exogenous enzymes is needed (O'NEILL et al, 2014).…”

The objective of the current study was to evaluate the effects of a commercial prebiotic (Hemicell ®) as a growth promoter on growth performance, intestinal morphometry and IL-1 and IL-2 gene expression in spleen of Japanese quail. A total number of 360 one-day-old Japanese quail chicks were randomly allocated into 4 equal groups. Group 1(control group) fed on the basal diet that not supplemented with prebiotic, group 2 fed on basal diet supplemented with 0.5 g Hemicell/kg diet, group 3 fed on basal diet supplemented with 1.0 g Hemicell/kg diet and group 4 fed on basal diet supplemented with 1.5 g Hemicell/kg diet. To evaluate growth parameters, 30 birds from each group were weighed weekly for six successive weeks. Spleen tissues were collected at 21 and 42 days after supplementation from all quail groups (control and experimental groups). At the end of the experiment, the results of the current study revealed that, feeding Japanese quails on diet supplemented with Hemicell resulted in improved growth and growth performance as indicated by increased body weight and weight gain. Also, intestinal morphometry revealed an increase in height and base width of intestinal villi in a dose dependent manner. Moreover, Real time PCR indicated upregulation of the IL-1 and IL-2 genes expression in a dose and time dependent manner. In conclusion, addition of β-mannanase in Japanese quail diets would have beneficial effects on performance and immunity in birds.

“…The use of enzyme complex in animal feeding improves the utilization of nutrients that would otherwise be unavailable (Leite et al, 2011), reflecting positively on the performance and reducing the pollution load of excreta (Opalinski et al, 2010). However, the inclusion of enzymes in formulations should be made carefully, because this additive may lose their biological activity during pelleting process, which involves high temperatures, moisture, and pressure.…”

Stability of enzyme complex solid-state fermentation subjected to the processing of pelleted diet and storage time at different temperatures

et al. 2016

-The effects of processing of pelleted diets and their storage time on the stability of the enzyme complex SSF (solid-state fermentation) were evaluated. Two diets were formulated with the same nutritional composition, differing only in the Schizochytrium sp. levels (0 g kg -1 and 50 g kg -1 ). The samples were collected during the following processing steps: mixing, then pelleting, and then oven. To evaluate the storage time, the diet ready after drying was considered as day 1. On this day, two samples were obtained, being one kept in a room with ambient temperature of 25 °C and another stored in freezer at -18 °C. At 15, 30, 45, and 60 days, sub-samples were taken. All samples from the processing step and storage time were sent to the laboratory and the following enzyme activities were measured: α-galactosidase, endoglucanase (carboxy-methyl-cellulase), xylanase, sucrase, amylase, lipase, and trypsin. There were no significant differences between the mixture and post-oven phase, except for the activity of α-galactosidase, lipase, and sucrase. For the storage temperature of 25 °C, no effect was observed for the activities of endoglucanase, sucrase, xylanase, amylase, and trypsin between the first (after oven) and the 60th day of the trial. As for the storage temperature of -18 °C, no difference was observed, except for the activities of endoglucanase and xylanase between the first and last day. Comparing the two types of storage (25°C and -18°C), there was difference only for the activity of galactosidase and trypsin at 60 days. The enzymes of the enzyme complex SSF studied remain stable during the processing of pelleted diet at 55 °C, maintaining activity for at least 60 days when stored at temperatures up to 25 °C.
