The feeding program for poultry has a major influence on profitability as feed cost accounts for up to 75% of production cost. Conventionally, it is assumed that requirements are either listed in tables or breeder nutrition guides. The Requirement Approach stems from the broken line, which is a simplification of bird response and implies that at different levels of energy or nutrients, efficiency ...

1.Background The impact on the environment, welfare issues, as well as the economic implications are challenging globally the modern livestock production. Employment of new nutritional strategies to limit the impact of the livestock production on the environment, have become an important task. Optimization in the feed formulation lowering the crude protein content, for the so-called N-reduced ...

Dr. Vijay Swami as I know protease doesn't show negative results in higher dose. But the negative is that it doesn't show positive results if protein/AA in feed are high; simply not substrate/space to improve.

Luciano Andriguetto YES, I agree to what you said the biggest advantage of using proteases is to destroy trypsin inhibitors, so whenever you get bad quality soya, you get good results; when you use proteases with good quality soya, we see less results with proteases.

ABSTRACT Enteric infections such as coccidiosis and necrotic enteritis in broilers may have a large influence on the endogenous amino acids (eAA) losses within the gastrointestinal tract (GIT). Although not much is known on this topic, more information is available on the effects of these diseases on the apparent ileal digestibility (AID) of amino acids. There are many factors that must be consid ...

Dr. Waldroup - in my opinion - is the foremost authority of brolier nutrition. I think it would be of great value if Dr. Waldroup would extend his comment regarding enzymes. Perhaps Engormix should invite him to make a presentation on this topic. Thank you.

For many years, when working with an enzyme producer, we suggested that a combination of enzymes would most likely be the most effective but almost to a man they screamed no, it would just be helping our competitor... not realizing it would enhance their own product.

Very good discussion. As many of us realize that it is the common misunderstanding of enzymes mode of action in general and the fact that they "Share" a common pool of nutrients, mainly energy and AA. This remains to be a subject that is not clear for the end user who struggles most of the times with the matrices provided by enzymes producers and the fact that some of them ignore such facts in pur ...

The reality - in my view- is that results with other enzymes different than Phytases are VERY equivocal. It is so for many reasons including: 1. Lack of precise info on feed substrate for the enzyme2. Poorly estimated energy values for ingredientes and formulas 3. Inter brand enzyme activities comparison today is close to impossible: units are completely different. 4. It is not certain if "purifi ...
