Feed Enzymes and Thermostability
Enzyme use in animal feeds has been around for a while, with the first reports of an enzyme product, being used in the 1920s. In the 50s and 60s, pioneering researches demonstrated the effects of enzyme addition to animal feeds, with early studies on the use of phytases for improving phosphorus availability in plant feed ingredients conducted in the early 1970s. The enzyme preparations employed in these studies were crude enzymes and only available in limited amounts. It was another 10 to 20 years later when the nonstarch polysaccharide (NSP) and phytase enzymes became available in industrial quantities.
During the past 30 years, the chemical nature of the compounds found in feedstuffs has been studied and provided the basis to create products, specific for individual substrates. With the recent developments in the areas of biotechnology and molecular biology, it is now possible to mass-produce feed enzymes for use in industrial animal diet formulations. In the present article, we will go over some of the key points regarding the implementation of enzymes in the current feed production industry, with an emphasis on enzyme termostability, but firstly…
Coated VS Intrinsically Thermostable Phytase Enzymes
Enzymes are a group of proteins known to catalyse more than 5,000 biochemical reaction types. In the animal feed industry, unquestionably the most commonly used enzyme is phytase. This enzyme catalyses the hydrolysis of phytic acid (high phosphorus compound found in abundance in grains, oil seeds and other plant origin fodders, that is normally indigestible by animals), while releasing the more utilizable inorganic phosphorus as a reaction product. In order to withstand the harsh temperatures of the feed pelleting processes, enzymes can be coated or intrinsically thermostable. However, for the purpose of achieving maximum efficacy, the latter are preferred.

The effect of the addition of VemoZyme P to the compound feeds for broiler chickens
Dr. Diyan Stoyanov, Institute of Animal Science, Kostinbrod, Bulgaria
In the last decades, a lot of studies have been conducted in relation to the use of exogenous enzymes in birds feeding. The effect of using NSP-enzymes and Phytase has been proven in a very convincing way. Nowadays, scientific researches have been redirected to ptotease. The arguments for that are very solid. The material costs of the feed for broilers have increased, as well as the price of soybean meal, which is a major source of protein in the blends for poultry. This requires seeking of new opportunities for reducing the content of soybean meal in the feeding of birds by compensating with better digestibility. In the past it was thought that birds produce enough protease for the digestion and the absorption of the protein ratio. However, there is recent data on the mechanism of their action and the need for protease has increased. The obtained results have been influenced by various factors such as the type of protease (acid, alkaline, neutral), its activity and dose, composition of the compound feed to which it was added (are other exogenous enzymes involved), age of birds, etc.

The application of phytase dates back to 1990. New aspect that has attracted the attention of scientists is the unconventional high doses of phytase, the effects of which can be significant. The concept of super doses of phytase was launched in 2012. These are doses higher than 1500 phytase Units/kg feed, or 3-4 times higher than previously recommended. The authors explain this fact with the presence of extra phosphorus, an effect probably due to the better digestibility of amino acids. They consider that some of these effects may be due to mechanisms including myo-inositol (energy source), as well as the complete degradation of phytate to inositol.
Effect of application of VemoHerb T in broiler parents flocks
Dr. Dian Stoyanov, Institute of Animal Science, Kostinbrod, Bulgaria
Since ancient times remedial plants and extracts are used in folk medicine. In the conditions of intensive stock breeding, times of complete ban of the application of antibiotic growth promoters, and demands of the market for animal products without drug residues, scientists drew their attention back to medicinal plants as a source of biologically active substances with certain physiological effects. They are a good prerequisite for the development of bio or organic stock breeding.

Herbal extracts show extraordinary results over the health of bee hives
An independent study recently has concluded that unique combination of dry extracts produced by Company VEMO 99 Ltd have extraordinary results over productivity and general health of the bee hives.
Why that news is so important?
Not only because of the economical effect but also because of the problems the bees have been experiencing recently. The bees population rapidly decrease. Phenomena such as "Mass death of bees", Colony Collapse Disorder (CCD), honey bee depopulation syndrome (HBDS) have been observed all over the world. Through the years various names of diseases have been given to that phenomenon: disappearing disease, spring dwindle, May disease, autumn collapse, and fall dwindle disease... But what has been happening since the winter of 2006 and is currently going on now is observed for the first time in the human history: Millions of bee hives have died.
