Problems solved by technology

However, due to the growth traits of livestock and poultry directional selection, optimized nutrient supply and precise breeding mode, the digestion and absorption frequency of livestock and poultry is in a high-intensity state, which seriously damages the integrity of the intestinal mucosa of livestock and poultry and damages their intestinal health , and even cause intestinal diseases
At the same time, it leads to the imbalance of intestinal flora and decreased immunity, and finally leads to the decline of livestock and poultry production performance
[0003] Due to the problems of high-density feeding environment, frequent immunization, and physiological characteristics in the late laying period in my country's laying hen farming industry, the production performance and egg quality of laying hens in my country cannot be well guaranteed.
Moreover, the annual loss of eggs due to eggshell quality problems in our country is as high as more than 10%, which seriously limits the development of laying hen farming industry.

Embodiment 1

[0026] Embodiment 1: Preparation of feed additive for laying hens

[0027] 1. Screening of fermentation strains

[0028] After a lot of experimental research, the freeze-dried powder of Lactobacillus plantarum BNCC187897 (purchased from China Microorganism Culture Collection Center, BNCC) and Bacillus subtilis AS1.9086 suitable for the mixture of wolfberry leaves, wolfberry stems, corn flour and sesame meal were selected (Purchased from the Culture Collection Center of the Institute of Microbiology, Chinese Academy of Sciences) As a fermenting microorganism, the fermented product is rich in nutrients and can fully degrade wolfberry leaves, wolfberry stalks, sesame meal and other materials to produce more active ingredients suitable for poultry.

[0029] 2. Medium

[0030] Nutrient broth (NB): 3g beef powder, 10g peptone, 5g sodium chloride, 1000mL distilled water. The pH value is 6.8-7.0, and it is sterilized at 121°C for 15 minutes.

[0031] Nutrient agar medium: on the ba...

Embodiment 2

[0054] Embodiment two: preparation of feed additive for laying hens

[0055] The difference from Example 1 is:

[0056] 1. In the fermentation substrate, wolfberry leaves, wolfberry stalks, corn flour and sesame meal are crushed and mixed in a mass ratio of 0.5:1.5:0.1:0.2, and set aside.

[0057] 2. Preparation of Feed Additives for Layers

[0058]Mix 70 parts of potato flour and 15 parts of fermented product and stir for 3-5 minutes until evenly mixed, then add 0.5 part of star anise powder, 0.1 part of thyme powder and 2 parts of medlar powder in sequence, and stir for 5 minutes until uniformly mixed.

Embodiment 3

[0059] Embodiment three: preparation of feed additive for laying hens

[0060] The difference from Example 1 is:

[0061] 1. In the fermentation substrate, wolfberry leaves, wolfberry stalks, corn flour and sesame meal are crushed and mixed in a mass ratio of 1.5:0.5:0.3:0.05, and set aside.

[0062] 2. Preparation of Feed Additives for Layers

[0063] Mix 80 parts of potato flour and 25 parts of fermented product and stir for 3-5 minutes until evenly mixed, then add 1 part of star anise powder, 0.3 part of thyme powder and 6 parts of wolfberry powder in sequence, and stir for 5 minutes until uniformly mixed.

Abstract

The invention discloses a laying hen feed additive and a preparation method thereof. The laying hen feed additive is prepared from the following raw materials in parts by weight: 15-25 parts of microbial fermentation products of Chinese wolfberry leaves, Chinese wolfberry petiole, corn powder and sesame seed meal 70-80 parts of potato powder, 2-6 parts of Chinese wolfberry fruits, 0.5-1 part of star anise, and 0.1-0.3 part of thyme. A preparation method of the laying hen feed additive is further designed. The laying hen feed additive disclosed by the invention is capable of improving anti-oxidation capability of laying hens and enhancing immunity of the laying hens; and thus, the laying hen feed additive is beneficial for improving production performance of laying hens and quality of eggs.Moreover, the preparation method of the laying hen feed additive is simple in operations and controllable in cost.

Description

technical field [0001] The invention relates to the technical field of poultry feed, in particular to a feed additive for laying hens and a preparation method thereof. Background technique [0002] With the rapid development of the livestock and poultry breeding industry, the livestock and poultry feed and feed additive industry is also expanding rapidly. There are various feed and feed additives that reduce the cost of raising livestock and poultry, improve the internal immunity and production performance of livestock and poultry, etc. in the market. However, due to the growth traits of livestock and poultry directional selection, optimized nutrient supply and precise breeding mode, the digestion and absorption frequency of livestock and poultry is in a high-intensity state, which seriously damages the integrity of the intestinal mucosa of livestock and poultry and damages their intestinal health , and even cause intestinal diseases. At the same time, it leads to the imbal...
