How matrix value of enzymes calculated?
That is not true. Matrix values express the amount of nutrients the manufacturer of an enzyme product believes the product can release. All enzymes are substrate specific, so the matrix value will be wrong if you add an enzyme in a diet with no substrate for that enzyme.

Field evaluation of feeding spray-dried plasma in the starter period on final performance and overall health of broilers

INTRODUCTIONSpray-dried plasma (SDP) is a highly digestible protein ingredient rich in functional molecules, manufactured from animal blood collected from federally inspected slaughter facilities, and spray-dried to preserve the functionality of its components (Coffey and Cromwell, 2001). It is a diverse mixture of functional molecules consisting of immunoglobulins, albumin, fibrinogen, lipids, gr ...

Trypsin Inhibitor, the hidden enemy in Soyabean Meal
brendon muko, Urease values of soybean meal should not be used as the best measure of optimum processing. measurement of the urease activity do not reflect the intensity of heat treatment of soybean meal beyond the threshold of urease. Chen et.al (2019) conducted a study to determine the levels of TI and UA in 414 SBM samples from 19 different countries and to validate whether TI and UA are correl ...

Effect of dietary supplementation of essential oil and organic acid alone or in combination in broilers
Thank you for your comment, Mangalmurti. The Novus essential oil blend product, NEXT ENHANCE® 150, is micro-encapsulated with a patented technology. Its physical properties, such as particle size, angle of repose, and compressibility, allow it to mix well at the low doses. To address concerns of some customers, we have a premix of this product that is 10X diluted with dosage increased 10X.

OH-Methionine and DL-Methionine are similar in sustaining laying performance and egg quality of Babcock layers
Hello Without data on feed composition it is impossible to draw any conclusions from this report. Please can you post the FULL composition of the diets, ie % inclusion of each and every raw material. Then at least we can determine if another nutrient is actually the limiting factor in performance. MPS

Ideal ratio of digestible methionine plus cystine to digestible lysine for growing Japanese quails

IntroductionQuail farming is very important for providing jobs and producing high quality protein at a low cost. Nutrition during the growing phase of the birds can influence their performance during the production phase. Most research has focused on the nutritional requirements of quails during the laying phase and there is little information about requirements during the growing phase. Quails ar ...

Forum: Characteristics of Effective Enzyme Solutions for Poultry Diets
I think everyone in this discussion made good comments. It seems to me that all that is needed is an underlying theory to fit all the various pieces into. This is the same for phytase and all the other enzymes: First, it should be accepted that responses to enzymes follow Michaelis-Menten kinetics. Enzymes do not give linear responses. This was very nicely illustrated by Shirley and Edwards, Jr. ( ...
