An optimal duck performance on growing and feathering with 100% efficient methionine sources: OHMethionine or DL-Methionine

Published on: 02/20/2020
Author/s : By Lv-Hui Sun, Huazhong Agricultural University (China) and Dolores Batonon-Alavo, Adisseo

The objectives of the trial described in the article were (i) to compare the effects of OH-Methionine compared to DL-Methionine on growth performance and feather growth of Cherry Valley ducks fed from 0 to 42 days and (ii) to determine the bio-efficacy of OH-Methionine (OH-Met) relative to DL-Methionine (DL-Met). The trial was published by Zhao et al.2018 in Poultry Science: Efficacy of 2-hydroxy...

Interesting Article. A useful one, to demonstrate how this kind of trial should be conducted. In terms of comparisons of nutrient sources, there are two golden rules; 1, make sure nothing else can limit the observable response; and 2, test the products at a levels where a response is likely. With this trial, evaluation of the diets indicates that both Lysine and Threonine were limiting for both phases; and AME was limiting for the Finisher phase. So the fact that no response was seen when comparing M+C sources was likely caused by these limitations. Furthermore, of all the treatments levels only the Basal diet and Group 2/6 were in a sensitive zone; Groups 3, 4, 5, 6, 7, 8 and 9 are likely in the plateau area of the dose response curve. Again, the lack of a difference in performance is therefore not surprising. So, a good lesson in the pitfalls to avoid! MPS
