Ricardo Hume Dear Ricardo, 100% agree with your opinion. CV 5% is easy to reach, because if we will spray methionine into the mixer, during the mixing process, feed mix becomes to be (theoretically, if mixer is well adjusted) 100% homogenic, in splite of different size and specific density of ingredients. After the end of mixing process, during feed transportation, stratification is possible, but ...

  Introduction The use of exogenous proteases in poultry diets has gained momentum during the last decade. The first commercial protease was introduced into the poultry feed market in the 1990s in combination with other enzymes, with the aim to increase the energy and protein digestibility of grain and oilseed meal based diets (Simbaya et al., 1996). A number of proteases are now available ...

Marc, see what other experts think about a CV = 10%. All About Feed Magazine Wayne Cooper Feed mill and machinery expert Expert opinion 18 May 2020 The CV of Ok, so this is a pet peeve of mine. This standard has been in place since 1985….forever! Is it not time to step up our game? I had actually thought our major challenge would always be medications. However, as medications are cut back, we ...

Dear Ricardo Hume Thank you for your comment and your interest in this video.In order to avoid any misunderstanding regarding the interpretation of the CV, let me clarify that, considering a normal distribution of the additive in a batch of feed (Gauss curve), a coefficient of variation (standard deviation/mean value) of 10% means that 68% of the mass of the batch contains between 90 and 110% of t ...

Dear Winston Samuel!Under the name "Phytase", there are a lot of different products on the market that have phytase activity. You would need to justify the correct choice of phytase. The high content of calcium B and inorganic phosphorus in the feed will inhibit the action of phytase. Phytase is useful in any climate.

Dear Peer Hansen I know about the effects of ozone on mycotoxins. Experiments that were conducted in the laboratory are difficult to translate into industrial production. 1. ozone Treatment requires exposure, that is, time. Industrial feed production is based on in-line technology, meaning there is no time for ozone action. If the grain (not feed!!!) pre-treated with ozone, you need separate bi ...

Dear forum participants.Some of You took offense at me because I said that adsorbent sellers are not selling the product, but fairy tales about the product. I can confirm that! This statement applies only to adsorbents. Sellers do not know the scientific basis of the product and repeat what they will be told about aflatoxin. Then the concept of "aflatoxin" is identified with the concept of "mycoto ...

Dear Jack Garrett!You state that: "Research on multiple chelated products in the market is absolutely necessary for the scientific community, but not necessary for individual companies to conduct." But how can you prove that your product is better than the competitor's?

Dear Enric Esteve - Garcia and Daulat Rehman Khan! I have not studied the comparative biological efficacy of L and DL-methionine. I conducted research for a different purpose and found that DL-methionine induces cytochrome P-450.This indicates the activation of the xenobiotic metabolism system. I conclude that D-methionine has xenobiotic properties. Based on this, some of it will be metabolized as ...
