“…Results of the present study confirmed that using amylase, protease, or they are combined at different periods did not show any effect on FI, BWG, and FCR. The results of FI in the present study were in line with Liu et al (2020) , who described no significant effect of amylase addition in the broiler diet on FI. In contrast, Lin et al (2019) observed no significant effect in FI with protease supplementation in a broiler diet.…”

Background: Feed additives that increase nutrient availability in feeds have gained a lot of interest. Aim: An experiment was conducted to determine whether amylase, protease and their combined supplementation affected broiler performance. Methods: Two hundred eighty (280) broiler chicks were selected and distributed randomly into 28 replicate pens with four treatment groups and seven replicates under Completely Randomized Design (CRD). A total of four diets were developed, having 0, 100g, 100g and 100+100g of control (AP0), amylase (A1), protease (P1) and amylase + protease (AP1)/ton of feed, respectively. Four replicates of each treatment were fed each diet. Each diet was randomly allotted to each group. Ad-libitum feeding was provided to the birds. The feeding program had starter and finisher diets. Upon completion of the experiment, three birds from each pen were slaughtered to analyze the carcass characteristics and organ weight. Results: Differences were insignificant between 100g/ton of amylase supplementation and FI, BWG, or FCR (P>0.05). Supplementation with 100g/ton of protease did not significantly affect FI, BWG, and FCR (P>0.05). Similarly, 100+100g/ton of amylase + protease addition had no significant effect on FI, BWG, and FCR (P>0.05). None of the treatments significantly affected carcass weight, abdominal fat percentage, dressing percentage, drumstick, wings, breast and thigh weights (P>0.05). In addition, there were no significant effects (P>0.05) on the weight of the heart, liver, gizzard, and spleen. Conclusion: In conclusion, amylase, protease, and their combined supplementation at a rate of 100g/ton of feed did not influence BWG, FI, FCR, carcass characteristics, or organ weight.

“…The greater AME N value was directly correlated with higher digestibility of nutrients such as ether extract ( EE ), CP, and starch, and also with better growth performance parameters such as body weight gain and feed conversion ratio ( Stefanello et al, 2019 ). On the other hand, Liu et al (2020) did not observe any effect of amylase on the digestibility of starch in a corn-based diet in their study.…”

“…Starch and protein can form mutual complexes ( Wang et al, 2020 ), however, amylase may disrupt these complexes, breaking the glycosidic bonds, and therefore increase the access of enzymes to proteins and amino acids. It has been reported earlier that a high level of RS is responsible for lower nitrogen retention ( Hejdysz et al, 2017 ; Liu et al, 2020 ). It can be expected that RS forms complexes with protein, thus decreasing its access to enzymes.…”

“…Several studies have shown that the utilization of amylase in poultry feed can increase body weight and feed conversion in broiler chickens, thereby reducing production costs and increasing feed efficiency (A. J. Kaczmarek et al, 2014;Liu et al, 2020;Onderci et al, 2006).…”

This paper focuses on the use of enzymes in effective and efficient poultry feed formulations. The introduction highlights the importance of good nutrition for poultry and the increasing need for innovative feed formulations due to limited availability and rising prices of feed ingredients. Enzymes are introduced as protein compounds that enhance nutrient digestion and absorption in poultry, potentially reducing feed production costs. However, their widespread use in Indonesia is still limited due to a lack of knowledge. The paper discusses the role of enzymes in poultry nutrition, including their involvement in digestion and nutrient absorption. It also emphasizes the essential nutrients required for poultry growth and development and the factors influencing their nutritional needs. The types of enzymes commonly used in poultry feed formulations, such as phytase, amylase, protease, and lipase, are explored along with their mechanisms of action. Research findings demonstrate the effectiveness and efficiency of using enzymes in improving nutrient availability and feed efficiency, ultimately enhancing poultry production productivity and sustainability. The paper concludes with recommendations for the development and application of enzymes in poultry feed formulations, highlighting the need for careful enzyme selection, dosage adjustment, and consideration of environmental conditions. Furthermore, the importance of integrating enzymes with other feed ingredients and adopting a comprehensive nutrition strategy is emphasized. Overall, the use of enzymes in poultry feed formulations offers significant advantages for modern poultry farming, but careful implementation and further research are necessary to optimize their effectiveness and efficiency.
