Modern xylanases show greater versatility

While xylanase enzymes have been available for a long time and experienced nutritionists routinely use them in pig and poultry diets, this does not mean that development of these types of products has stopped. Xylanase feed products were originally developed to be applied to wheat based diets, often with the specific aim of reducing viscosity problems caused by highly viscous wheat varieties. Now their reach is much further.
The first generation xylanase products worked reasonably well for the purpose of reducing viscosity in barley or wheat based diets, but occasionally showed weaknesses in terms of... read more »

Betaine hydrochloride: An essential nutrient in broiler diets

Betaine is a known functional nutrient in broiler nutrition, which was in the past mainly used as betaine anhydrous extracted from sugar beets. Nowadays, it is also available as betaine hydrochloride from synthetic production. read more >

Proteases in broiler diets require careful selection

While the animal feed industry has successfully managed to procure commercial enzymes that enhance the efficiency with which broilers derive energy and phosphorus from their feed, it has not been so successful in the case of protein. Earlier attempts at using proteases in commercial conditions were, at best, inconsistent. This is perhaps not surprising, given that many of the first proteases to enter the feed market were developed for the detergent industry and only later adapted for use in feed. read more >

Enzymes, tiny catalysts poultry feed can’t do without

Doing without enzymes in poultry feeds nowadays is almost unthinkable. For optimal performance and minimal nutritional waste enzymes are first choice ingredients. Still a lot is unclear and ongoing research slowly unravels the possibilities of these tiny catalysts. At the 22nd Annual Australian Poultry Science Symposium held in February of this year quite a few papers were devoted to enzyme use, which are summarised in this article. read more >

Temperature as a criterion for choosing the right phytase

That exogenous (added) phytase has become a staple ingredient in most pig and poultry diets worldwide is hardly surprising. It is rather the more perplexing issue of having to pick the ‘right’ phytase from a myriad of available products, all with more or less similar claims. Clearly, this is quite confusing, but when heat resistance is the criterion, the choice is easier. read more >

Boost your risk management capability with enzymes

Risk management is a hot topic and companies in most industries are assigning resources to risk management. Enzymes offer an effective tool in risk management strategies to counter raw material price volatility in the animal feed industry. With increasing prices of feed phosphates and other key raw materials, producers should consider increasing the inclusion rate of phytase in their feed, as well as maximising nutrient availability via the use of carbohydrases and other relevant enzyme activities. read more >
