“…A recent study by Woyengo et al (87) showed that using amylase, NSPase, or a combination of amylase and NSPase in the phytase-supplemented basal diet further improved (P < 0.05) ileum digestibility to 63.4, 69.9, and 67.3%, respectively. However, the dietary nitrogen corrected apparent metabolizable energy value was not affected by the addition of phytase, amylase, or a combination of amylase and NSPase.…”

“…However, the dietary nitrogen corrected apparent metabolizable energy value was not affected by the addition of phytase, amylase, or a combination of amylase and NSPase. Woyengo et al (87) concluded that the addition of amylase and NSPase to broiler phytase-supplemented diets is beneficial to improve apparent metabolizable energy corrected by nitrogen. In another study by Sateri et al (88), they showed no significant effects of olive meal and enzymes on growth performance and on cecum microflora.…”

This study was executed to investigate the effect of supplementing three multienzyme levels (0, 0. 1, and 0.2%) with two types of diet [standard diet (SD) vs. low-density diet (LDD)] on immune response, blood hematology and biochemistry, antioxidant status, and organ histology of broilers during 1-38 days of age. A total of 216 unsexed 1-day-old Arbor Acres broiler chicks were randomly distributed, on a factorial design (2 × 3), to six treatments each with six replicates. There were six chicks per replicate. Results showed that LDD significantly decreased body weight gain (BWG) of broilers, but did not affect the European Production Efficiency Index (EPEI). Addition of multienzymes at both levels (0.1 and 0.2%) significantly increased BWG and improved EPEI, compared to the control diet. Alanine aminotransferase (ALT), aspirate aminotransferase (AST), malondialdehyde (MDA), lymphocyte, lymphocyte transformation test (LTT), and phagocyte activity (PA) were significantly higher for LDD than the SD, but eosinophil was lower. Supplementation of multienzymes significantly decreased ALT, AST, and MDA, compared to the control group, but increased packed cell volume (PCV), hemoglobin (Hgb), lymphocytes, and monocytes. Immune organs, such as spleen, thymus, and the bursa of Fabricius were significantly increased with multienzyme supplementation. It could be concluded that multienzyme supplementation at either 0.1 or 0.2% to SD or LDD improved EPEI and immune status of broiler chicks.

“…Together, dietary AM/AP ratio of 0.23–0.35 is suggested to maintain higher growth performance in broilers. Amylase has been widely reported to promote the digestion and absorption of starch and improve the growth performance of animals (Oliveira, Silva, & Mesquita, 2017; Woyengo, Bogota, Noll, & Wilson, 2018; Zhu, Hu, Hou, Zhang, & Ding, 2014). Conversely, the current results showed that dietary 3,000 U/Kg α‐amylase had no significant effect on growth performance and 6,000 U/Kg α‐amylase reduced ADG in broilers.…”

Aims and scopeThe Journal of Animal Physiology and Animal Nutrition publishes original papers on hypothesis-driven research in the fields of animal physiology, physiology and biochemistry of nutrition, animal nutrition, feed technology, and feed preservation but not manuscripts presenting fish (or other aquatic non-mammals) nutritional or growth topics. The journal is a forum for presenting articles on basic and applied research, thus making new findings, methods, and techniques easily accessible and applicable in practice. Reviews of the most important specialized literature are also included.

“…Enzymes are commonly employed to decrease anti-nutritional substances and to improve animal performance [8][9][10][11]. Multienzymes containing carbohydrases and phytase were found to enhance the utilization of energy, protein, and minerals by chickens [12][13][14], suggesting that higher amounts of alternative feedstuffs could be used in the presence of enzymes [15]. Rye, wheat, and barley grains, which contain high levels of soluble-NSP, particularly arabinoxylans (pentosans) pectin, and β-glucans may reduce the rate of gut emptying and affect small intestinal transit time, block fats from digestion and thus absorption, therefore, cannot be incorporated into chickens' diets at high concentrations unless exogenous enzymes are adequately applied.…”

“…In the process of depolymerization various polysaccharides in the diet, enzymes may produce manno-, galacto-, gluco-, or xylo-oligomers, which are similar to prebiotics and which may facilitate the proliferation of health-promoting bacteria such as Lactobacillus and Bifidobacterium [21]. Cellulase is a viscosity-reducing enzyme and is a group of enzymes that hydrolyze cellulose or β-(1,4)-glucan [2,14]. Protease enhanced degradation of soybean meal protein in the gut notably, and the mode of action of protease are wholly allied with the digestibility [14].…”

The aim of this work was to study the continuous or intermittent impact of a multienzyme supplement on growth performance, nutrient digestibility, and blood metabolites of broilers, and to evaluate production index of dietary supplementation. A total of 315 unsexed day-old Arbor Acres broiler chicks were randomly distributed to seven treatments groups, keeping initial body weights similar, in 35-floor pens (replicates) of nine chicks per replicate (pen) and five experimental units per treatment. All experimental groups were fed the same basal diet and administered seven multienzyme treatments: the 1st group (control) did not receive any enzyme supplementation; the 2nd, 3rd, and 4th groups were administered multienzymes at 0.5, 1.0, and 1.5 mL/L drinking water, respectively. Each enzyme supplemented-group was divided into two subgroups, with additives being applied either continuously (24 h/day) or intermittently (12 h/day) from 1 to 35 days old. Regardless of administration method, multienzyme supplements at 1.0 mL/L water along with a corn-soybean meal diet increased the body weight gain (BWG) by 7.8% compared to 0.5 mL/L water during days 1–21 of age. In addition, 1.5 mL/L water significantly improved BWG by 5.1% of broilers compared to 0.5 mL/L water during days 1–35 of age. Enzyme supplementation at 1.5 mL/L water significantly enhanced feed conversion ratio (FCR) by 4.3% during days 1–21 of age, and FCR by 5.2% and European production index (EPI) by 10.4% during days 1–35 of age compared to the group on 0.5 mL/L water. For the whole period, there were improvements of beneficial consideration in BWG (4.0%), FCR (4.0%), and European production index (8.2%) due to continuous multienzyme supplementation at 0.5 mL/L water compared to the same dose added intermittently. A similar trend was observed due to intermittent multienzymes at 1 mL/L drinking water that resulted in increased BWG by (6.4%) and improved FCR by (6.7%) and EPI by (12.7%). Intermittent administration significantly increased feed intake of broilers during 22–35 days of age compared to continuous supplementation. Multienzymes at different doses did not significantly affect the digestibility of nutrients, blood serum biochemical constituent, inner body organs, and markers of functions of liver and renal organs. In conclusion, the highest BWG and the best FCR and EPI for the whole period were from broilers given continuous 1 and 1.5 mL/L drinking water or intermittent multienzyme supplementation at 1.5 mL/L drinking water. Furthermore, intermittent supplementation of enzymes at 1 mL/L drinking water and continuous supplementation at 0.5 mL/L drinking water can be investigated in further experiments as a tool to improve broiler growth performance and economic traits and to decrease the cost of enzyme application.
