Great points! Matrix values of enzymes should be used cautiously as they might not always be accurate. Different factors such as birds’ age, dietary antinutrients, disease, and environmental conditions can affect the efficacy of enzymes in diets. Another concern in using these values is related to enzyme additivity issues. Nutritionists must be careful when reviewing the total matrix applied ...

Zahed Abbasi, I would just comment that to keep a look out on feed intake also, if it drops it could be a sign that indeed the enzyme is working, but because energy to all othe nutrients ratio wasn't changed that the birds now have decreased daily intake of all nutrients and could therefor also show no gain in performance parameters, even in some circumstances show a loss! But that is not the enz ...

Dear Sam, Of course, if the grain portion of a recipe changes frequently, the lab has to adjust the multi-enzyme formula each time. This takes a lot of time from the laboratory staff. In this case, it is advisable to use a universal multi-enzyme mixture like Kronozim-Multi. It is more expensive than regular feed, but for farmers with unstable feed formulas, the all-purpose mix is the solution to a ...

Herbal methionines were introduced when there was a severe shortage of d.l.methioninine. herbal methionine is a powder which has comparatively higher level of methionine compared to other grains and cakes which are known to contain different levels. Some body analyzed the samples of herbal methionine sold in the market and found 3% d.l.methionine with the same test used for measuring the methioni ...

I should like also to comment from Dr. Marchenkov regarding "vegetable methionine". As Dr. Wu correctly states, methionine is methionine; an amino acid with a clearly defined structure INDEPENDENT of the source. I have seen numerous products claiming to be "Herbal methionine" and these materials are not methionine, and do not contribute methionine. When used in correctly balanced and formulated di ...

Although I agree with the author of the article about the difficulties of practical application of the ideal protein concept, nevertheless, I believe that this concept has the right to exist as a mathematical model. It can be used to get closer to the most efficient protein absorption. But in practice, fluctuations in the composition of grain raw materials and protein sources are observed, and the ...

Water is a fascinating subject. I would like to caution that in not all circumstances will decreasing water PH along with essential oils eliminate pathogens (e-coli, etc..) . If your sanitation program is failing (due to application, dose, resistance etc..) then the problem of having bacteria present will accelerate with adding any organic substances. One also must be careful that the product do ...
