Luis Fernando you are right. I am always against using enzymes on top; it is not only Waste of money but additionaly destroy the mineral balance as Phytase does. It costs extra. As the best case enzymes on top do not work and money to buy them are just lost

Very good points were raised in this discussion and we see that different approaches are possible. Congrats to all of you. I also would like to add some points that I think we need to take into consideration to better use enzymes: 1-we need to know the amount of antinutritional factors and how they affect each specific feed, for example, soluble Arabinoxylans from one raw material can affect the d ...

The enzyme products that have been developed are of great value to the broiler producer. We know commercial enzyme products release nutrients from the bulk ingredients that make the ingredients more valuable. Typically, a successful product improves value well beyond its cost. And we know that enzyme products named for the same enzyme can have other beneficial enzymes from the fermentation process ...

Hi Everyone. Thanks for addressing the good and the bad about formulating multiple enzymes in the same diet. As a result of the great improvements in Enzymes and other Additives, people like Dr. Frank Ivey with his Broiler Opt, and others who know how to model animals have in effect taken the problem out of the structured Linear Programs that i and others have developed over the last 40 years. And ...

The prices are a moving target. But yes that paper is AUD not Euros. We can say that as time goes by, the purified AA sources will likely get cheaper as demand picks up and economy of scale is realised. The next thing to be considered will be sustainability. On first thought, most will think purified sources will be more sustainable than SBM. However one needs to consider the input materials to pr ...

We often forget (or forget to teach) that the mathematical program known as linear programming, often known as "least cost", when in actuality it can be used to determine either least cost or maximum profit. One of the problems that the author I think overlooks is that for many nutrients feeding less than a requirement can lead to disastrous results, especially when it deals with trace mineral, vi ...

Dr. Afrouziyeh has been of great service to provide a recipe and instruction for creating a non-linear least cost formulation for those that are less certain of the nutritional content of their feeds. The more variation one experiences in the ingredients they buy, the more chance there is, with linear programming, to reach a feed that fails dramatically, as Dr. Waldroup pointed out earlier. When u ...
