Problems solved by technology

At present, there are single emulsifiers and compound emulsifiers on the market. The emulsifying ability of a single emulsifier is limited, but it is targeted; the emulsifying effect of a compound emulsifier is better, but the effect in specific aspects is lacking
At this stage, most of the research on emulsifiers is carried out on broil...

Embodiment Construction

[0039] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] 1 Materials and methods

[0041] 1.1 Test material

[0042]1.1.1 Test raw materials

[0043] The emulsifier used in this experiment is the solid emulsifier produced by Hangzhou Kangdequan Feed Co., Ltd. - double milk energy, the main components: monoglyceride, sucrose ester, sorbitan ester.

[0044] 480 300-day-old laying ducks were provided by Hubei Shendan Health Food Co., Ltd., and animal feeding experiments were carried out at the Fuli Egg Duck Farm of Shendan Health Food Co., Ltd. in Anlu City, Hubei Province.

[0045] 1.1.2 Test equipment

[0046] The test instruments are from the Animal Husbandry and Veterinary Research Institute of Zhejiang Academy of Agricultural Sciences and the public experimental platform of Zhejiang Academy of Agricultural Sciences, see Table 1.

[0047] Table 1 Test e...

Abstract

The invention discloses an application method of emulsifier to influence on laying duck productivity and fat metabolism. The application method comprises the following steps of randomly selecting 480healthy laying ducks which are 300 days old and have similar weights in a test, randomly dividing the laying ducks into four groups, repeating 6 laying ducks in each group, repeating 20 laying ducks in each group, pretesting for 30 days, and formally testing for 8 weeks; the laying ducks in a control group are fed by basic ration; the laying ducks in a test group I ares fed by basic ration and 100g/t of an emulsifier; the laying ducks in a test group II are fed by basic ration and 150 g/t of the emulsifier; and the laying ducks in a test group II are fed by basic ration and 200 g/t of the emulsifier. Results show that the emulsifier has an improvement effect on the daily average feed intake, the feed-egg ratio and the laying rate of the laying ducks on the overall level, wherein the concentration of 100 g/t is the optimal additive amount. In addition, the emulsifier has no significant influence on duck egg quality and serum fat metabolism indexes, but can regulate fat metabolism by improving the cecum microbial flora structure.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry production, and in particular relates to an application method for the influence of an emulsifier on the production performance and fat metabolism of laying ducks. Background technique [0002] In recent years, the laying duck breeding industry has developed rapidly, and the output of laying duck products has increased rapidly. As a result of long-term artificial selection, the production performance of laying ducks has been continuously improved, and people's requirements for ingested nutrition have also gradually increased. In order to meet the high-yield and high-nutrition requirements of laying ducks, feed companies generally add fat to feed to meet their energy needs. However, the price of oil is high, adding high-priced oil means an increase in cost and a decrease in profit, and when the amount of added oil exceeds the digestion capacity of animals, it will cause waste of oil ...
