Embodiment 1

[0017] Example 1: A method of adding a feed additive containing coated lipase to broiler feed to improve the energy utilization rate in the feed and reduce the feed to meat ratio.

[0018] The specific production methods of the above feed additives are as follows:

[0019] 1) Take 400 parts of Aspergillus niger lipase, 289 parts of silicon dioxide, 150 parts of gelatin, 150 parts of dextrin, 10 parts of sodium hydroxymethylcellulose, and 1 part of calcium propionate in proportion;

[0020] 2) Put the mixture in 1) into a mixer, add water and mix evenly to make a paste;

[0021] 3) Put the paste in 2) into a swing granulator to make wet granules, and pass through a 14 mesh screen;

[0022] 4) Put the wet particles into the coating machine and tumble for 3 minutes, adjust the speed to 30-40r / min, and spray the coating liquid (acrylic resin, gelatin and water mixed) evenly on the surface of the wet particles to make wet particles;

[0023] 5) Dry 4) the wet granules through a 35°C dryer to ...

Abstract

The invention provides a broiler chicken feed additive containing lipase and a production method thereof, and especially provides a broiler chicken feed additive containing coated lipase and a production method thereof. According to the broiler chicken feed additive containing the coated lipase, lipase is protected by adopting a physical method of low-temperature coating that the key point is to control digestion rate of components of a coated lipase layer in the glandular stomaches of the broiler chicken. Therefore, contents of the components in the coated lipase layer and particle size of the coated lipase are determined so as to ensure that the lipase is not inactivated under the influence of the acidity of the glandular stomach when the lipase is passing through the glandular stomach;and the lipase exposes to the small intestines just in time when the lipase is passing through the small intestines so that lipid utilization ratio is improved so as to reduce feed conversion ratio, and thus, feed cost is decreased. The broiler chicken feed additive containing the coated lipase is a broiler chicken feed additive with significant effects.

Description

(1) Technical field [0001] The invention relates to a lipase feed additive, in particular to a broiler feed additive containing coated lipase. (2) Background technology [0002] Energy is an important nutrient component of broiler feed. The energy ratio of feed plays a vital role in the growth of poultry. However, due to the continuous increase in the cost of energy feed, especially the price of fat, how to improve the utilization rate of energy in feed and reduce fat The amount of addition and cost saving have become a problem for the breeding industry in recent years. [0003] Lipase is a key enzyme for fat metabolism. It can hydrolyze fat into free fatty acids, glycerol and monoglycerides for animal absorption and utilization. Studies have shown that monogastric animals themselves can secrete endogenous lipases, but young animals and animals in special periods have poor digestive functions or insufficient endogenous lipase secretion, resulting in low fat digestion and absorptio...
