This study was conducted to determine the standardized ileal digestibility (SID) of amino acids (AA) in hydrolyzed feather meal (HFM), flash dried poultry protein (FDPP), poultry meal (PM), and meat and bone meal (MBM) fed to broiler chickens and pigs. Four semi-purified diets and a nitrogen-free diet were prepared. Experiment 1 was conducted with 416 male broiler chickens [initial body weight (BW ...

Dear Ms. Peris, Thank you for your comments. The first objective of this trial was to determine the relative bioavailability of Met sources in broilers. As stated by Jansman et al., (2003) proper studies are those that include a basal diet clearly deficient in Met, and at least 3 levels of supplementation of the test products. As in any dose-response trial, it is crucial that enough data points ar ...

Conclusion
The present study conducted at Schothorst Feed Research resulted in an average bioavailability of MHA-FA and diluted DLM65 of 65% and 61%, respectively compared to MetAMINO® considering the overall growth and carcass parameters.
These results demonstrate that the relative bioavailability of MHA-FA is significantly lower than its active content of 88% and consistent with the 2018 ...

Heat stress continues to be a challenge, and any contribution to knowledge is welcomed. However, I would correct some of the points raised recently. Use of methionine sources will inevitably reduce heat stress, as correct formulation to SID amino acids will reduce crude protein content and thus energy expended in excreting excess nitrogen.The choice of methionine source needs to account for this. ...

Introduction
Broiler diets are commonly supplemented with dry DL-methionine (DL-Met; 99% active substance), liquid methionine hydroxy analogue-free acid (MHA-FA, 88% active substance) or dry methionine hydroxy analogue-calcium salt (MHA-Ca, 84% active substance). Several broiler trials have demonstrated that the relative bioavailability (RBA) of Met hydroxy analogue products (MHA-FA or MHA-C ...
