Problems solved by technology

[0003] In the large-scale breeding mode, layer hens are raised in cages, with high population density, many stress factors, poor digestive system and reproductive system functions, and affected body functions, which is not conducive to maintaining a good egg production level and egg quality
However, the currently used feed additives often have disadvantages such as high cost, poor efficacy and stability, and strict requirements on the storage environment.

Embodiment 1

[0037] The formula of the feed additive is: 20% glycerol monolaurate, 25% glycerol dilaurate, 35% glycerol monostearate and 20% carrier (silicon dioxide) in terms of weight percentage.

[0038] 180 44-week-old Hailan brown laying hens were randomly divided into 4 groups with 3 replicates in each group and 15 chickens in each replicate. The control group was fed basal diet, and the experimental groups 1, 2, and 3 were added with the above-mentioned feed additives with a mass fraction of 0.1%, 0.2%, and 0.3% on the basis of the basal diet respectively. The test period was 8 weeks.

[0039] The experimental chickens were raised in a stepped cage, fed twice a day, and picked eggs once. Feeding, drinking, cleaning, disinfection, and epidemic prevention were carried out in accordance with the current measures of the chicken farm. During the experiment, the temperature and humidity of the feeding farm were recorded every day on a repeat basis. Egg samples were randomly selected one day b...

Embodiment 2

[0047] The formula of feed additive is: 40% glyceryl monolaurate, 15% glyceryl dilaurate, 30% glyceryl monostearate and 15% of the carrier (starch) in terms of weight percentage.

[0048] Ninety 18-week-old Hailan brown laying hens were randomly divided into 3 groups with 3 replicates in each group and 10 chickens in each replicate. The control group was fed basal diets, and the experimental groups 1 and 2 were added with 0.05% and 0.1% of the above-mentioned feed additives on the basis of basal diets respectively. The test period was 35 weeks.

[0049] The experimental chickens were raised in a stepped cage, fed twice a day, and picked eggs once. Feeding, drinking, cleaning, disinfection, and epidemic prevention were carried out in accordance with the current measures of the chicken farm. During the test, the temperature and humidity of the feeding farm were recorded every day with repetition as the unit. Egg samples were randomly selected one day before the end of the test period...

Embodiment 3

[0056] The formula of the feed additive is: 10% glycerol monolaurate, 30% glyceryl dilaurate, 50% glycerol monostearate and 10% of the carrier (silicon dioxide) in terms of weight percentage.

[0057] 135 44-week-old Hailan brown laying hens were randomly divided into 3 groups with 3 replicates in each group and 15 chickens in each replicate. The control group was fed basal diet, and experimental groups 1 and 2 were added with the above-mentioned feed additives with a mass fraction of 0.2% and 0.3% on the basis of the basal diet, respectively, for a total of 8 weeks.

[0058] The experimental chickens were raised in a stepped cage, fed twice a day, and picked eggs once. Feeding, drinking, cleaning, disinfection, and epidemic prevention were carried out in accordance with the current measures of the chicken farm. During the experiment, the temperature and humidity of the feeding farm were recorded every day on a repeat basis. At the end of the test period, the chicken jejunum was t...

Abstract

The invention discloses an application of a feed additive in preparation of a laying hen feed for improving egg quality and egg laying capability. The feed additive includes, by weight, 10-45% of glycerol monolaurate, 10-30% of glycerol dilaurate, 30-50% of glycerol monostearate, and 0-20% of a carrier. In feed additive, the glycerol monolaurate, the glycerol dilaurate and the glycerol monostearate are combined together, so that the feed additive significantly improves the egg quality and improves the egg laying capability of a laying hen.

Description

Technical field [0001] The invention relates to the technical field of feed additive processing, in particular to the application of the feed additive in the preparation of layer feed for improving egg quality and laying performance. Background technique [0002] Eggs are a common food on people's daily table and an important source of human animal protein. With the improvement of people's living standards and food safety awareness, its quality has received more and more attention. People eagerly hope that green, nutritious, and pollution-free products will be launched. Therefore, "natural, green and pollution-free" is the theme of the world's layer industry development in the 21st century. [0003] In the large-scale breeding mode, the laying hens are reared in cages, with high population density, many stress factors, poor digestive and reproductive system functions, and physical functions are affected, which is not conducive to maintaining good egg production and egg quality. ...
