synthetic amino acid on broiler performance

Dear Authors, 

Good article about phytoconcentrate herbal nd synthetic amino acid on broiler performance.The Ayurvet product seems to have mixture of some herbs claiming to have activity of Choline, methionine, Lysine and Biotin. Choline, methionine, lysine and biotin have different roles in the body and how can a single product perform all these functions? Additionally, could you please state the concentration of Choline, Methionine, Lysine and Biotin of this product?

Dear Reader, The product is a mixture of some SPECIFIC HERBS in a PARTICULAR RATIO & PROPORTIONS with a scientifically well known & proven acitivity of that of 4 different amino acids for which references are quoted in the research paper. Please refer the results and discussion in detail to compare the effects of herbal product vs. synthetic additives to clarify how a single product can replace all amino acids. You may also communicate with first Author Dr. A.B. Kanduri, Assistant Professor, Dept. of Animal Nutrition, Veterinary College Udgir, Maharashtra, email adress: drajaykanduri@gmail.com for further clarifications about the experiemental study and results of herbal product.

Thank you, I would definitely contact Dr. Kanduri for further clarification. However, I feel that the ratio and proportion that you are referring to should have been quoted in the above paper for the purpose of clarity.
