Summary
Methionine supplementation is crucial for poultry diets. Economic analysis shows methionine hydroxy analog-free acid (HMTBA) offers 81-86% of dl-methionine
Area of Science:
- Animal Nutrition
- Poultry Science
- Amino Acid Metabolism
Background:
- Methionine is an essential amino acid for poultry, often limiting in corn-soybean meal diets.
- Supplementation levels directly impact poultry production economics.
- Comparing methionine sources like dl-methionine (DLM) and methionine hydroxy analog-free acid (HMTBA) is vital.
Purpose of the Study:
- To evaluate the relative bioavailabilities and economic values of different methionine sources.
- To address the challenge of determining optimal feeding levels for various methionine supplements.
- To provide an economic analysis comparing HMTBA and DLM in poultry diets.
Main Methods:
- Utilized a common plateau nonlinear model to estimate relative bioavailabilities.
- Performed a meta-analysis of published experimental data.
- Applied economic analysis to previous meta-analysis results, considering broiler value and feed costs.
Main Results:
- Previous meta-analysis indicated 79% and 81% relative biological efficiencies for HMTBA compared to DLM for ADG and feed efficiency, respectively.
- Economic analysis revealed HMTBA's relative value to DLM for body weight (BW) and average daily gain (ADG) ranges from 81% to 86%.
Conclusions:
- A single optimal methionine supplementation level is challenging to establish due to differing source efficiencies.
- The economic value of HMTBA relative to DLM is dependent on market factors like broiler price and feed costs.
- Understanding these economic differences is crucial for optimizing poultry production profitability.

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least squares (OLS)...
