Fat, as an important nutrient substance for energy supply and storage, is necessary to all animals. It participates in animal organism constitution and provides necessary fatty acid. It has nutritional physiological action of adjusting metabolism. The energy content of fat is 2.25 times than carbohydrate. It not only meets the demand of higher energy concentration to animals, but also supplies extra energy effect. It improves energy utilization rate and net energy value of feedstuff, production performance of animals, relieves effects of cold or hot enviroment to animal production performance. As fat is a solvent of fat-soluble vitamin and pigment, it promotes absorption and utilization of such materials and help to put colour on, like animal skin, shank, yolk yellow. If add specific fat with rich polyunsaturated fatty acid (PUFA), it will enrich animal products with special PUFA, like DHA, EPA. Then turn out animal products with specific value of healthcare. To add fat into animal feed have many other functions besides above nutritive functions, like decrease dust, improve appearance of feed, reduce mechanical wear to prolong its life, lower cost, etc. Therefore, fat is a necessary feedstuff to young, growing or high-producing animals.
2 Influence factors to digestion and absorption of fat
(1) Different bioavailability to diffenent fat. (See Table 1)
Table 1: Relevant metabolic energy standard to different kind of fat
metabolic energy standard (kcal/kg)
refined palm oil
rice bran oil
It is mainly because diffenent fat kind has diffenent saturation and length of fatty acid chain, which cause such big difference in efficiency.
(2) The more addition of the same fat is, the lower bioavailability will be
With the increase of fat addition, its digestibility decrease rapidly. For example, when addition reaches 3%, compared with the addition 1.5%, the digestibility lowers 15%-25%, because the excess addition surpasses animal digestive ability.
(3) With different age in days, health and growth condition of animals, the bioavailability of fat is different
The smaller age in days of animals is, the lower availability of fat is. The digestibility is influenced by animal health condition, too. The digestibility of young animals is still in process of growth, falling ill will also effect animal digestive system.
(4) Compared with the extra addition of fat, the fat in feedstuff is lower too much in bioavailability
The fat in raw materials such as corn, soybean is in form of combination, its degestibility and absorptivity are lower. Extra addition of fat is in uncombined state, so its degestibility and absorptivity are higher.
(5) Anti-nutrient factors
Tannins decrease the digestibility of fat. If the concentration of crude fiber is at a high level, it will lower the activity of lipase.
Phytic acid will lower the activity of lipase.
Aflatoxin can effect activity of lipase and secretion of cholate. It will induce young animals’ steatorrhoea.
Non-starch polysaccharides restrains activity of lipase.
Lipozyme is the specialized enzyme product positioned on solving digestion and utilization efficiency of feed fat all sidedly. It’s developed by Sichuan Habio Bioengineering Co., Ltd with bioengineering leading technologies and core processing technique. Lipozyme adopts biochemical enzymatic reaction, innovated traditional physical process of digestion and utilization, promote digestive and utilized rate-limiting step of feed fat under precondition of stable under thermal and acidic enviroment.
Charactors of Lipozyme
1 Lipozyme adopt biochemical enzymatic reaction style to promote utilization efficiency of fat and extra fat in feed stuff, optimize feed formula, lower costs and improve feed quality.
2 Lipozyme improves animal digestive and absorptive system environmentally friendly. The heavy burdens of digestive system will be reduced because fat is digested and utilized more efficiently. By this way, it reduces multiple diseases that may be induced by digestive and absorptive obstacles.
3 The HTHP (high temperature high pressure) environment is the main obstacle to service efficiency of enzyme preparation in feed processing. Habio modern biotechnologies can ensure Lipozyme biological action and superiority of enzyme.
4 Habio has top liquid submerged fermentation and advanced post-process technology, which fully eliminate the safety risk of unstable quality by making the Lipozyme stable under acidic and hot circumstance.

(2)Storage stability of Lipozyme
(3)Influences of high temperature and high humidity to Lipozyme: broad range of temperature and activity, excellent thermostability, more than 85% activity residual rate after 85°C pelleting process.
(4)pH curve of Lipozyme: wide range of pH, higher activity under pH range from 3 to 11, have better function in animal digestive tract.
Specification and Usage
10 000U/g (GBT 23535-2009)
Applicable to weanling piglet, piglet, poultry, aquatic livestock and ruminant etc. Recommended additive amount: 200g/t in complete feed.
Usage is based on actual producing condition
1 Direct adding Adding 200g Lipozyme per metric ton into complete feed directly on the basis of original formula.
2 Formulation method Changing the content of raw materials and reduce the metabolic energy (50Kcal) of formula, then adding 200g Lipozyme, thus reduce the formula cost while equaling with or exceeding the feed effect of the original formula.
