Embodiment 1

[0028] Example 1. Experiments on the effectiveness of adding bile acids to broiler chickens in the 0-21 day diet

[0029] 1. Materials and Methods

[0030] 1.1 Test substance

[0031] The bile acids used in the test were provided by Shandong Longchang Animal Health Co., Ltd., specifically including: hyodeoxycholic acid 8.00%, hyodeoxycholic acid 70.67%, chenodeoxycholic acid 19.61%.

[0032] 1.2 Experimental animals and design

[0033] The test selected 432 AA broiler chickens with an average initial body weight of 43.18g at 1 day of age, and randomly divided them into 4 treatments, each treatment had 6 replicates, and each replicate had 18 chickens. The diet of the control group was corn soybean meal type diet. The test was divided into two stages: 0-21 days and 22-42 days. The basal diets of the four treatment groups were added: 0, 40, 60 and 80 mg / kg of bile acids in the early growth period (0-21 days).

Embodiment 4

[0181] Embodiment 4, repeated verification test of bile acid in the production of 817 broiler chickens

[0182] Subjects of the experiment: 817 broiler chickens in Tianzhai Village, Gaotang, 5450 birds, were randomly divided into two treatment groups, blank control group (1450 birds) and test group (4000 birds).

[0183] Experimental method: In the same shed, two water lines were used for the control group and the test group respectively. The test started at 10 days old (July 13, 2014) (it is recommended to change to 1 day old if it is for customers to see), and ended at 48 days old (2014-8-19), a total of 38 days. Longchang bile acid in the test group drank 150g / T of water until the end of the test, and the control group was blank.

[0184] Experimental results: The number of 817 broiler chickens in each group was recorded in detail, the number of slaughtered, the weight of slaughtered, feed intake, and the mortality rate. (Chickens are infected with influenza virus at the ...

Abstract

The present invention provides an application of bile acid in preparing a feed additive for broiler chickens. An experiment result proves that an addition of 60-80 mg / kg of bile acid in daily diet from 0-42 days can effectively improve the performance and slaughter performance of the broiler chickens; the addition of 80 mg / kg of the bile acid in the daily diet from 0-42 days can significantly reduce serum uric acid levels in the broiler chickens; and an addition of 60-80 mg / kg of the bile acid can enhance activities of duodenal lipoprotein lipase and lipase and inhibit an activity of hormone-sensitive lipase, helps improve utilization of lipids in the broiler chickens, reduces use of body lipids, and thus improves the growth performance of the broiler chickens. The addition of the bile acid in the feed can promote synthesis of very low density lipoproteins in the liver, accelerates the transport of the lipids from the liver to adipose tissues, reduces the deposition of the lipids in the liver, can effectively prevent occurrences of fatty liver and hepatobiliary syndromes, and reduces a death and culling rate.

Description

technical field [0001] The invention belongs to the field of animal feed additives, and in particular relates to the application of bile acids in the preparation of feed additives for broilers. Background technique [0002] In recent years, the price of energy feed raw materials, especially oil, has been rising continuously. How to improve the utilization rate of energy in feed, reduce the amount of added oil, and reduce the harm caused by high oil to save costs has become the focus of attention. Adding substances with emulsifying function to the feed to promote the emulsification of oil, thereby improving the digestion of oil by broilers has been generally recognized. Commonly used include soybean lecithin, lecithin, glycerin fatty acid ester, monoglyceride, sucrose ester, etc. According to literature reports, lecithin, as an exogenous emulsifier, has a certain effect on improving the digestion and absorption rate of tallow in feed and improving production performance, but ...
