“…In terms of economic evaluation, fish fed 50% HPDDG with protease achieved best FCR and ECR values (Table 8) compared with the other diets, while fish fed the control diet without DDGS and protease supplementation recorded the highest in total feed cost/kg fish gain. These results are consistent with Alam, Howlider, Pramanik, and Haque (2003) who observed that feed cost per kg live weight was reduced by addition of exogenous enzymes in broiler diet. In addition, Khan, Sardar, and Siddique (2006) concluded that enzyme supplementation is more feasible and economical to obtain maximum profitability from broiler production.…”

High‐protein distillers dried grains (HPDDG) is a co‐product of ethanol production that uses prefractionation technology. A 70‐day growth trial was conducted to investigate the effect of partial replacement of dietary soybean meal by high‐protein distiller's dried grains (HPDDG) with protease enzyme supplementation (PROXYM ULTRA®) on growth performance, physiological parameters and histological changes of the intestine of European sea bass, Dicentrarchus labrax fingerlings. The results indicated that increased dietary HPDDG levels up to 50% of HPDDG supplemented with protease significantly increases growth performance and feed utilization and improved FCR of sea bass. In addition, replacement of SBM by HPDDG supplemented with protease enhanced feed intake efficiency and the health status of fish. Haematology and serum biochemistry (haemoglobin (Hb)), red blood cells (RBCs), white blood cells (WBCs) and humeral immune parameters including total protein, globulin, cholesterol, lysozyme activity and total antioxidant capacity significantly increased with increase in HPDDG supplemented with protease in the diets. Results of this study indicated that HPDDG supplemented with protease is a good alternative protein source for aquaculture feed and can be included up to 50% as a replacement of SBM without compromising growth performance and physiological parameters of sea bass.

Problem statement: Endogenous enzymes of broilers cannot adequately digest nonstarch polysaccharides and subsequently the ingestion of high levels of soluble NSP leads to increased digesta viscosity and reduced nutrient digestibility and absorption. Supplementation of NSPs degrading enzymes may remove the anti nutritive effects of NSPs and release some nutrients (starch, protein) from these elements. Therefore, in a completely randomized design the effects of a multi-enzyme (Endofeed W produced from Aspergillus niger, with minimum activity of 2250 u g⁻¹ xylanase and 700 u g⁻¹ β-glucanase) supplementation on performance, carcass characteristics, carcass composition and some blood parameters in Cobb 500 broilers fed on corn-soybean meal-wheat diets were studied. Approach: A total of 150 one-day-old broiler chicks (Cobb 500) were used in a completely randomized design with 2 treatments and 3 replicates. The main ingeridients of diets included corn, soybean meal and wheat. The enzyme levels added to the diets were 0.00 (control) and 500 mg kg⁻¹ DM. Results: Enzyme supplementation significantly improved relative growth, energy efficiency and protein efficiency from 11-28 days of age. Adding enzyme significantly decreased body weight gain, feed intake and improved feed to gain ratio, energy efficiency and protein efficiency from 29-44 days of age (p<0.05). Relative growth, energy efficiency and protein efficiency was increased and body weight gain, feed intake and feed to gain ratio was decreased by enzyme supplementation from 1-44 days (p<0.05). Enzyme addition significantly increased carcass and thighs + drumsticks percentages at 44 days of age. Adding enzyme significantly increased the concentration of blood Triiodothyronine (T3) at 28 and 44 days and reduced the concentration of blood Thyroxine (T4) at 44 days of age. Enzyme inclusion increased the concentration of blood total cholesterol at 10, 28 and 44 days of age, however triglyceride concentrations increased at 10 and 44 days (p<0.05). The concentration of blood uric acid was significantly decreased at 28 and 44 days in broilers fed enzyme supplemented diets. Conclusion: Results of this study indicated that supplementation diets with 500 mg kg⁻¹ multi-enzyme (Endofeed W) in corn-soybean meal-wheat based diet improved broiler chickens feed to gain ratio, carcass yield and it can change the concentrations of thyroid hormones and some metabolites in blood, but it had not significant effect on carcass composition

“…Adding protease and amylase decreased it, and both enzymes were ineffective in the cold season. The results obtained from the study on the addition of feed form or enzyme, the effect on FI was found to agree with Ahmed and Abbas (2013), Shabani et al (2015), Stefanello et al (2015), and disagree with Alam et al (2003), and Hajati et al (2009); On FCR, agree with Jafarnejad et al (2010), Torres et al (2013), Stefanello et al (2015), and disagree with Zakaria et al (2010). Thus, it can be expressed that the enzyme addition used in the current study has multiple enzymatic activities.…”

Moreover, the addition of multi-enzyme to the feed increased (p<0.05) the BW in d14-42 according to Alam et al (2003), in d0-42 according to Dersjant-Li et al (2015), and in d11-42 according to Taheri and Shirzadegan (2017) while it did not affect BW in d1-21 according to Zhu et al (2014), in d1-28 according to Hajati (2010), and in d7-35 according to Mohammed et al (2018). However, Yu and Chung (2004) reported that adding glucanase and xylanase to the feed increased BW in the hot season.…”

This study was conducted to investigate the effect of dietary supplementation of exogenous multi-enzyme complex and feed form on growth performance, slaughter characteristics, nutrient digestibility, phosphorus (P), calcium (Ca), and nitrogen-corrected apparent metabolizable energy (AMEn) utilization in broilers fed corn–soybean meal diets. A total of 312 male one day-old broiler chicks (Ross 308) were allocated to 6 dietary treatment groups with 13 replicates (4 birds each) in a 2×3 factorial arrangement of treatments in a randomized design, which includes mash (M) or pellet (P) diets supplemented with three levels of a multi-enzyme complex (0, 125, or 175 mg/kg) for 42 days. The results indicated that the addition of 175 mg/kg multi-enzyme complex to pelleted feeds (P175) significantly increased (p<0.05) the body weight and feed intake of the broilers during the grower period. The feed conversion ratio (FCR) was significantly improved (p<0.05) by adding the multi-enzyme complex to the pelleted feeds. The feed form * multi-enzyme interaction was significant on d0-21 for BW and FI and all three periods in FCR (p<0.05). Mash feed decreased the European Production Efficiency Factor (EPEF) ratio compared to that of the pelleted feed, and it was observed that EPEF increased (p<0.05) linearly with an increase in the multi-enzyme complex added to both the mash and pelleted feeds. Although there was no difference among the groups regarding the carcass yield and relative organ weights, the gizzard weight increased significantly in chickens fed with mash feeds (p<0.05). In addition, the difference between treatment groups in terms of total tract nutrient digestibility does not differ (p>0.05) significantly, while the highest (p<0.05) AMEn utilization was found in the P175 group. As a result, the pelleted feed form and the increased level of multi-enzyme supplementation improved the performance and efficiency of broiler production.
