Hi to all:
The first purpose of enzyme using is to use the nutrient that without exogenous enzyme are not usable by endogenous enzyme . The other most important purpose is gut health .
I advise to use enzyme like those that are effective on the NSP in breeder and layer first on top , after using evaluate the body weight ,egg weight and production percent .if there be increase in body and egg we ...

Mechanisms of Action for Phytase Enzymes in Poultry Diets for enhanced Phosphorus availability to Birds.?
1. Since first commercial utilisation, phytase has mainly been considered to be a tool to increase phosphourus (P) availability/digestibility from vegetable sources and so to reduce the inclusion of higher cost P sources. ??
2. Here, phytase releases the P bound in the phytate molecule, incr ...

I. INTRODUCTION Phytases have been heavily researched for decades and been used commercially since the early 1990s). Phytase from microbial origin is therefore added to monogastric diets as it can reduce the incorporation of inorganic P sources in the feed, reducing feed cost and P excretion in the environment. Phytate is the main storage form of phosphate in plant matter and in vegetable feed ing ...

Nutritionists have access to various ingredients that fulfill methionine (Met) requirements of broilers. Amino acids (AA), such as DL-methionine, are nearly 100% bioavailable while methionine hydroxy analogs are shown to be relatively less bioavailable.Thus, this experiment aimed to determine the efficacy of using a 65% DL-methionine and 35% limestone dilution product (65DLM) compared to a methion ...

Pellet Quality
For purposes of this paper, pellet quality will be equated to the ability of pellets to withstand repeated handling without excessive breakage or fines generation. There are many factors that affect pellet quality, but the following will be discussed in some detail:
· formulation· ingredient particle size· mash conditioning· feed rate· die speed& ...

ConclusionThe 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 EFSA ...

1. IntroductionHumphry Davy, a British chemist, was the first to isolate and investigate the chemistry of calcium (Ca) and to recognise it as an essential component of bone in 1808. Ever since, it has been the subject of a voluminous amount of research in both human and animal nutrition. Today, the biological significance and economic importance of Ca in animals are intuitive. Calcium is the most ...

Dear Alireza, thank you for confirming the concept by an additional data set. I like to pronounce, that validating the equivalency of DL-Met and the methionine hydroxy analogue at 65:100 replacement ratio not only results in same animal performance but also in considerable cost savings when using DL-Met provided the price ratio between mentioned products is not 65%, which means the price of the hy ...

DL-Methionine (DL-Met, 99%) and liquid DL-2-hydroxy-4-methylthio butanoic acid (methionine hydroxy analogue-free acid, MHA-FA, 88%) are often used in commercial poultry feeds to meet the requirements for Methionine+Cysteine (M+C). However, differences in chemical properties and absorption decrease the relative bioavailability value (RBV) of MHAFA, which corresponds to 65% of DL-Met for performance ...

there is nice report.
We replaced in diet 65 part of DL-MET with 100 part of MHA in trial on 6000 broilers in iran. Results indicated that body weight and FCR were the same in both groups confirming 65% RBV of MHA.
