Dear Dr.Zeeshan, betaine is natural osmolyte substance. It hold the water inside the cells. Paralelly betaine reduced fat content and increased meat content in broilers. Saudi Arabia poultry farms use betain against heat stress in high doses, till 2 kg/tonn of feed, according to recommendations of Danisco Animal Nutrition/DuPont Biotechnologies. Of course, other methods against heat stress, like s ...

Thank you very much for that announcement for people how take tannins in the form of black tea everyday, but the reason for poultry is different because we use that pure material as therapeutic as in case of diarrhea as astringent, but when it increases it will cause constipation besides precipitation of some feed elements

Generally, tannin application has a long story at poultry, as well as at the swine fattening. I remember a feed additive polyphenols-containing product from castanian, produced by company Lek, Republic of Slovenia. From other side, it is necessary to use right doses of polyphenols; because overdosing can cause negative effect on metabolism and FCR. Polyphenols in a small quantities are scavengers ...

Dear colleagues, thanks a lot for your opinion. From my point of view, it is important to understand the difference between NSP&phytase and proteases. Monogastric digestion system does not contain NSP&phytase enzymes; however, it contains endogenous proteases. Question is activity of these proteases is not enough for complete hydrolysis of feed protein. The advanced poultry crosses like Co ...

Luis Mansilla San Miguel Dear Luis, you are absolutely right. Also one important point is oil (naturally contained or added extra). In splite of high energy content, oil is causing pseudo-coating substrate effect and decreased effectivity of other feed enzymes. So, lipase is very helpful to make it soluble.So, it reason to use together phytase, NSP-enzymes and lipase, too. Unfortunately now pri ...

Luciano Andriguetto Dear Luciano, absolutely agree with you! Many different martix values in a single feed receipt is unreasonable. My firm have experience of one matrix values table for a enzyme blend containing 6 different enzymes activities. Question is that such matrix not easy to develop, necessary to perform a lot of laboratory tests in vitro, and than follow in vivo. Buy it is really corre ...

Dear Dr. Manangi, generally, corn/soya broiler feed is poor source of phytates. So, in this situation P release is highly depending on phytase properties (pH optimum, side activities of other enzymes, phytase solubility). It is possible to increase effectivity of phytase B by increasing of their dosage. In these situation is important to calculate what is cheaper: to use more advanced enzyme or to ...
