| Enzyme | Inclusion | Species | Enzyme Inclusion Period | Effect | Diet | Ref. |
| B-mannanase | 0, 200, 400 PPM | Broiler | 7 - 21 days | β-mannanase significantly (+) blood glucose and anabolic hormone homeostasis, FCR, digestible energy, and digestible amino acids | Corn-SBM based diet (Low and High SBM) | [114] |
| B-mannanase | 400 gm per ton | Broiler (Challenged with coccidiosis at day 14) | Day 1 to 42 | No improvement in performance but contributed to quality and intestinal health. Enzyme supplementation overall resulted worst FCR | Corn-Soya based |
[115] |
| B-mannanase | 800 IU per Kg Feed | Broiler | 1 - 44 days | (+) BWT gain (day 2-22) but no effect on BW gain or Feed intake for entire research period | Corn-Soya based (Standard energy and low energy) |
[116] |
| Xylanase | 1 gm per Kg Feed | Broiler | 7 - 21 days | (+) BWT gain at 21 days, (+) feed to gain ratio, (+) ileal digestibility of CP, Starch, Soluble & Insoluble NSP, (+) TTD of DM, CP, Starch, Soluble NSP | Wheat based diet | [117] |
| Xylanase (GH 11) | 0.06% (600 UX/g) | Broiler | 8 - 35 days | Supplementation did not affect the digestive utilization of rye or wheat diets, No improvement on FCR | Rye and Wheat based | [118] |
| Phytase | 150, 300, 600, 1200, 2400, 24,000 U per Kg Feed | Broiler | 1 - 16 days | (+) BWT gain, Toe ash %, Nutrient utilisation by above 150 U per g. Furthermore, the 24,000 U/kg of diet (+) toe ash percentage and the utilization of several nutrients beyond that of the lower doses of phytase. | Corn-soy based | [119] |
| Phytase (Ronozyme) | 0, 250, 500, 750, 1000, 2000 FTU/Kg | Broiler | Day 0 to day 42 | Phytase linearly (+) growth performance fed P and Ca deficient diet with 2000 FTV showing greatest (+) on BWT gain, FCR, Tibia ash, AR of Ca & P, AME relation to NC | Corn-Soybean | [120] |
| Phytase | 2.5 AcPU/Kg phytase B-acid phosphatase activity | Layer | 50 to 60 weeks layer | (+) mean egg wt., shell strength and Ca-P retention | Corn-Soybean (P deficient) | [121] |
