Dr. Piotr Stanislawski You are right. Enzymes work all the time, but the extent of the effectiveness of enzymes depends upon many factors, briefly said as feed related, animal related and .....factors. For instance, the bird's growth rate has a huge potential to influence the extent of birds response to exogenous enzymes or nutrient composition or ingredient' makeup of the diet. So, the exogenous ...

Thanks for this nice article. though, there is no much difference between performance data, but 4 light saving is still a big achievement.

Juarez Donzele though theoretically it could be right, however, mostly it depends upon the growth rate of the birds as it is the case even in most feed additives. Immediate access to feed and water is more important in fast-growing birds than moderate or slow-growing birds.

Martin Smith, It is correct, actually, birds with higher growth rates are more sensitive to any restrictions either water, feed, space, etc. but if they have enough time to stay in the barn, for sure they would compensate the lag, partially or totally dependent upon the rate of restrictions.

Very good topic, but before accepting this idea generally we have to adopt the idea of synthetic amino acid fortification of diet to compensate for limiting amino acids. though in poultry we have adopted all plant-based diet and it seems very well, but still we need more research to determine why fishmeal based diets perform better than fish meal free diet. Is this related to higher amino acid dig ...

Hello there. Based on my personal experience with phytase, beside considering phytase nPP equivalency (the value depend upon phytase origin and level), one should be very careful in considering phytase matrix value (for other nutrients such as amino acid, Ca, etc.) in practical diet formulation.
