Problems solved by technology

Due to the fast growth cycle of broilers and vigorous development and metabolism, the application level of diets is high, and the traditional corn-soybean meal feed is difficult to meet the high energy demand of broilers during the growth process. For this, there are feeds with additional oil added to the feed recipe appears
[0003] However, the digestive organs of broilers are not fully developed at the young stage, and the endogenous bile acid secretion is not sufficient, so it is difficult to fully emulsify the fat in the feed, which greatly

Example Embodiment

[0024] Example 1:

[0025] This embodiment provides a feed additive based on lipase, which comprises: a composite emulsifier 0.05%; lipase 0.15%; wheat bran is 98%, and the lipase is obtained by black maushan. The enzyme activity of lipase is satisfied with the following conditions: 20000u / g ≤ lipase enzyme activity ≤40000U / g.

[0026] Among them, the composite emulsifier comprises: 80% of lysated lecithin, 15% sucrose ester, 5% bile acid.

[0027] At the same time, the present embodiment also provides a method of preparing the above feed additive comprising the steps of:

[0028] S1, according to the corresponding proportion of composite emulsifiers;

[0029] S2, weigh the composite emulsifier, lipase and carrier of the above ratio, first compound the composite emulsifier to the carrier, stirred for about 5-8 min, mix well, then add the fat enzyme 3 times to the compound emulsified composite emulsification In the agent; preferred, each time the addition of one-third of the fa...

Abstract

The invention discloses a lipase-based feed additive, a preparation method and application thereof and a broiler feed. The lipase-based feed additive comprises the following components in percentage by weight of 0.05-0.20% of a compound emulsifier, 0.02-0.15% of a lipase; and the balance of a carrier. The lipase-based feed additive can supplement insufficient secretion of endogenous emulsifiers and lipase, improve the decomposition efficiency of feed grease and promote healthy growth of livestock and poultry. Meanwhile, the lipase-based feed additive can be prepared into a low-energy feed to be applied to feeding of livestock such as broilers and the like, the addition amount of grease is reduced, water and excrement phenomena are reduced, the abdominal fat rate of the livestock is greatlyreduced, and the growth effect of the livestock is better.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a lipase-based feed additive, its preparation method, application and broiler chicken feed. Background technique [0002] Along with the rapid development of modern broiler breeding industry, broiler has become one of people's main meat products. Due to the fast growth cycle of broilers and vigorous development and metabolism, the application level of diets is high, and the traditional corn-soybean meal feed is difficult to meet the high energy demand of broilers during the growth process. For this, there are feeds with additional oil added to the feed The recipe appears. [0003] However, the development of various digestive organs of broiler chickens is not perfect, and the secretion of endogenous bile acids is not sufficient, so it is difficult to fully emulsify the fat in the feed, thus greatly limiting the digestion and absorption of fat. Furthermore, emulsification is only a...
