Apparent Metabolisable Energy of Common Cereal Grains for Broiler Chickens is Influenced by Bird Age
Published: June 12, 2023
Summary
I. INTRODUCTION Cereal grains such as wheat, sorghum, barley and maize are commonly used in poultry diets as the main source of energy. Knowledge on the metabolisable energy content of cereal grains is critical for their efficient use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME has been the globally accepted system for de...

Hello and respect to the authors of the article
I read your article. Some cases are questionable according to my research experience.
- First, considering that you used cereal grains. Apparently no commercial enzyme was used.
- The effects of age, especially in broilers, are predictable due to the lack of development of the digestive system, which is effective in the amount of metabolizable energy. It is clearly stated in scientific sources. But what was your scientific motivation? Was there a vague scientific reason why this research was done?
- I wish you would consider things like the effect of the internal enzyme of the bird's body according to the age of the bird or the internal enzyme of the edible substance according to the physicochemical structure of each edible substance in the calculations. until the results were clearer and more practical and recommended in the poultry industry.

Based on the results found, I have the impression that the energy levels for sorghum are better than those for corn?
