A large number of commercial proteases have chymotrypsin type activity and oriented toward hydrophobic amide bonds. What type activity does your protease have? Would it affect other supplemental enzymes such as amylase or phytase?

Methodology to calculate amino acid requirements in e-Rhodimet® Nutrition Guide (eRNG) Commonly, amino acid requirements are estimated in experimental trials using optimized criteria such as daily weight gain, feed conversion ratio and breast meat yield in different mathematical models (quadratic, broken line, exponential). These trials determine the requirement in each amino acid for a given ...

Well, interesting, but I am not so optimistic: as I am from the country of limestone - Italy - I well know how large the variation in Ca digestibility can be among various geological origins of limestone, even without mentioning the particle size issue...The other question of giving Phytase a Ca value or not, in my experience when many years ago in Europe we started to give a Ca value to Natuphos ...

Dear Rami Unfortunately still many of the nutrients in feed specification for poultry is crude, like CP , CF , EE and of course Ca. Ca is usually over supplied to the poultry diet from many sources like: Drinking water (as a rule of thumb poultry take water twice the feed intake) , Carrier in premix , concentrate , pro-prebiotics also as anti-caking agent in SBM. For example when you add 1 kg ...

Each phytase has an optimum pH with ftu’s conveying its relative activity under that specific condition. Phytases first act during storage in the crop with pH’s varying between 4-6 over varying durations. This ingests is conveyed into gizzard where pH’s decrease to 2-3 again over varying durations. Phytases of different pH optima continue to function through crop and gizzard only ...

All short chain organic acids used in animal nutrition have pKa between 3.8 to 5.0 and, if not protected with vegetable fat, do not pass the duodenum at significant concentrations as they will be absorbed and used as energy sources by different routes metabolic.Some organic acids such as formic, sorbic and benzoic have a higher efficiency than others in controlling gram-negative bacteria such as S ...
