Thank you for the detail, it helps a great deal. Evaluating the diet against Babcock recommendations, we find the diet deficient in energy ( - 100 kcal), threonine (4%), isoleucine (12%) and valine (6%). This is further exacerbated by the fact that feed intake is about 10% reduced against breed expectation, no doubt due to high ambient temperature. Of course, animals need a certain amount of each ...

In 2019, Evonik launched a new science-based training program called the ‘Evonik School of Animal Nutrition’ to help its customers achieve optimum performance and profitability with minimum environmental impact. This short video summarizes the events so far and provides insight into the participants’ experiences. It features Martin Smith, our Technical Director for the MEA region, Ansgar Jaegar, S ...

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

OKUN Babatunde In principle, all methionine sources are good. It depends on the price and the biological equivalence you assign to each source.

Further to this comment. I often do costing and training exercises looking at the impact of NOT using supplemental amino acids in commercial diets. Every time - in every situation - addition of a methionine source results in the highest cost saving and the highest reduction in crude protein content. As methionine is first-limiting amino acid in poultry feeds, this is not altogether surprising.Of c ...

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 ...

OK. Quite a nice article, but difficult to evaluate. There is no mention of milk production, which would be important as all health limits on M1 are based on concentration per litre milk, not per animal. Using your numbers above and the higher 6.2% transformation (carry over is a very poor term) this would give an M1 level of 10.5 µg per cow per day, reducing to 6.9 µg. Assuming 25 lit ...

Reply to Hamid Ibrahim Ismail;
The basis of any meaningful trial to compare sources of a single nutrient must start from a situation where that nutrient is the one limiting the performance parameter being monitored. In this situation we are evaluating methionine (more accurately M+C) and its impact on laying performance ie egg numbers, weight, and total mass. One should usually choose a point in t ...

This video is factually incorrect. Methionine is an essential amino acid, meaning that in higher animals it cannot be synthesised; it must be consumed within the diet. Plants and micro-organisms can synthesise methionine.
Whenever a properly designed and conducted comparison trial is conducted, the equivalence of these herbal products is invariably around 3%. In other words, they are NOT effecti ...
