I. IntroductionMethionine plus Cysteine (Cys) requirement of poultry and swine has been determined using graded levels of DL-Met. Currently, Aviagen recommends 0.95, 0.87, and 0.83% SID Met plus Cys for starter, grower, and finisher phases of Ross 308 broilers (Aviagen, 2019). Cobb recommends 0.88, 0.80, and 0.74% SID Met plus Cys for the respective growth phases (Cobb, 2018). Similarly, Brazilian ...

Daulat Rehman Khan I have a similar experience. Often times non-protease products such as phytase will have a greater and more consistent uplift in amino acid digestibility than proteases. In these situations it is likely more about reduction in endogenous losses, or breakdown of complexes (phytate interactions for example). I do believe in the POTENTIAL for proteases, but not in any commercially ...

Dear Mr. Tümer, thank you for the question. If I correctly understood, do you mean why we used anti coccidial?We tried to simulate the actual practical diet, therefore, we tried to keep the formulations as close as possible to the practical feed formulation.

In one of my experment, we observed that the protease has no significant improvement in the amino acids digestiblities in corn, SBM and Wheat based diet. It was an independent university research. There is a lot of discussion about the matrix values of the enzymes which are advocated by the producers. In fact, it need to be critically evaluted by the feed mill nutritionists and try to establish th ...

Dear all,
For the feed mill nutritionists, who want to know exactly the practical application of L-Methionine in their formulation and want to discuss the benefits of using L-Methionine in practice please contact me directly. Kind regards,

Tanaji Valmik Lokare thank you for your interest. By using L-Methionine in practical formulation you can use minimum 5-10% higher available Methionine matrics value than the normal Methionine Sources.
in this case you can save some money on the formulation cost. If you need more details and exact formulations examples please contact me. Kind regards.

This is an extremely interesting study for me. Without going into details, the results are quite expected. However, due to what part of the reduced use of DL-methionine logically, we should expect that due to D-methionine, which is foreign to the body. About 30 years ago, I found that DL-methionine in chickens was induced by cytochrome P-450 in the liver. Cytochrome is induced by a number of forei ...

1. IntroductionBetter growth, economy and environment-friendly commercial broiler production is limited to the right amount of available amino acids for efficient utilization in animal body. All of the crystalline amino acids supplemented in commercial poultry production are in their natural (L-isomer) form except methionine (Met), which may be utilized in its synthetic (D- and L-isomers) form in ...
