Feed enzyme preparation introduction and application of key points
Trifanz has a range of high quality anaesthetic face masks available in six sizes from neonate to large adult.
This Anesthesia Mask by Trifanz Medical can be used for anesthesia, respiratory or resuscitation use. Anesthesia mask features clear flexible faceplates with a contoured cushion that creates a gentle seal with the patient`s face. This disposable mask is meant for single-use only and has a universal fit connector. This cushion is a soft, pliable air-filled cushion that includes an inflation valve on the top and hook ring. This Anesthesia Mask is Non-sterile and Latex-free, using only high-quality, medical grade, clear PVC. This mask follows ISO standard sizing and is available in a range of sizes for adult, pediatric and infant use. Masks are individually bagged with color-coded rings for size identification.
The silicone anesthesia face mask can be repeated use and autoclaved at 134℃

Enzymes are biocatalysts produced by living cells that catalyze specific biochemical reactions. The enzyme preparation is a biological product having catalytic function after the enzyme is purified and processed.
2, feed enzyme preparation principle
Crack plant material cell walls, effectively degrade feed anti-nutritional factors, supplement endogenous enzymes, increase feed nutrient utilization, increase nutrient utilization, reduce feed formulation costs, thereby increasing production performance; reduce fecal excretion, reduce wet dung, slow down Faecal stickiness, reduce environmental pollution, improve poultry house environment; Degradation of oligosaccharides can effectively print the colonization of pathogens in the intestine, regulate intestinal flora balance, reduce intestinal diseases of livestock and poultry, improve the health of livestock and poultry, and improve group immunity. Expand the amount of non-conventional feed ingredients, reduce feed costs, and stabilize feed product quality.
3. Principles for the use of feed enzyme preparations
Feed enzyme preparations should be targeted for both diet and animals. These two principles should be the basic principles for the design of multienzyme systems for feed enzyme preparations. The principle of enzyme formulation is designed according to the specificity of the feed and the principle of enzyme formulation is designed based on the specificity of livestock and poultry.
4. Determination of feed enzyme formulation
A. Fully understand and study the functions and properties of each single enzyme species. B. Use precise chemical analysis methods and methylation analysis techniques to understand the structure of feedstuffs (from: premixed homes), chemical properties and their component degradation. The desired enzyme system. C. Monitor and simulate the activity of digestive enzymes in healthy animals to find out the enzyme system that the animal needs to replenish. D. After determining the enzyme species, establish equations based on the general data of enzymatic properties and digestive physiology, and derive the approximate enzyme activity range. E. The best formula was selected through animal experiments and in vitro digestion tests.
5, feed enzyme preparation post-processing technology
The post-treatment technology of the feed enzyme preparation differs from the post-treatment for the purpose of purification in the biochemical engineering and refers to a post-treatment technique aimed at improving the stability of the enzyme and having a fixed-point release capability. The effectiveness of post-processing technology is one of the criteria for measuring the quality of a feed enzyme product.
6. Feeding enzyme preparations
Enzyme preparations are one of the safest, most effective and most promising feed additives. However, due to the complexity of the biological characteristics and laws of the enzyme preparation itself, many problems remain unclear. The actual application effects of the enzyme preparations are still unstable and are increasing. The efficiency of feed utilization, reduction of environmental pollution, improvement of animal production levels and economic efficiency have not been fully utilized. To solve these problems, the standardization of enzyme activity analysis methods, the stability of enzyme preparations, the relationship between enzyme preparations and dietary components, the relationship between enzyme preparations and endogenous enzymes, enzyme preparation and feed technology must be The relationship between the system and other aspects of systematic research.
