Sulfur Amino Acids requirements in Hybrid Converter Tom turkeys using DL-Methionine and OH-Methionine

04/05/2022

A trial conducted recently at the Missouri Contract Poultry Research aims to:

  • determine the digestible SAA requirements of Hybrid Converter male turkeys fed increasing doses of either DL-Methionine (DL-Met) or OH-Methionine (OH-Met) from 0 to 28 days
  • compare the effects of the two Met sources on the performance of turkeys

3,200 male Hybrid Converter turkeys were raised from 0 to 28 days in floor pens. Birds were fed a corn-soybean meal-based diet formulated to be low in sulfur amino acid (SAA). Methionine was added in the form of DL-Methionine (DLM) or liquid OH-Methionine (OH-Met), to create 7 different levels with a mid-level chosen to be the estimated digestible SAA requirement.

The combinations of different explanatory variables and mathematical models led to different requirement determinations. Overall, the estimated requirements are slightly below or matched the positive control’s which offered 1.02% of SAA.

Requirement estimates were similar between the two Met sources, independently to the equation used.

The conclusions are :

  1. OH-Met and DL-Met similarly sustained turkeys’ growth performance from 0 to 28 days.

  2. TSAA requirements in turkeys are similar for both OH-Met and DL-Met.
