Description

Technical Field

[0001] The invention relates to the technical field of poultry feed, in particular to a laying hen feed additive containing rosemary and a preparation method thereof. Background Art

[0002] Feed is the general term for food for raising animals. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. With the rapid development of livestock and poultry farming, the livestock and poultry feed and feed additive industries have expanded rapidly. Various feed additives have appeared on the market to reduce the cost of raising livestock and poultry, improve the immunity and production performance of livestock and poultry, etc. However, due to the growth traits of targeted breeding of livestock and poultry, optimized nutrition 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, damages their intestinal health, and even causes intestinal diseases. At the same time, it leads to intestinal flora imbalance and reduced immunity, and finally leads to a decline in livestock and poultry production performance.

[0003] Due to the problems in my country's laying hen farming industry, such as high-density breeding environment, frequent immunization and physiological characteristics in the late egg-laying period, the production performance and egg quality of laying hens in my country cannot be well guaranteed, which seriously restricts the development of the laying hen farming industry. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Summary of the invention

[0004] The invention aims to overcome the defects described in the background technology, thereby realizing a laying hen feed additive containing rosemary and a preparation method thereof.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present invention is: a laying hen feed additive containing rosemary, which is composed of the following raw materials in parts by weight: 50-60% of glucose, 15-20% of rosemary, 2-6% of ferrous sulfate, 3-4% of zinc sulfate, 1-2% of calcium hydrogen phosphate, 2-3% of calcium carbonate, 2-4% of vitamin A, 2-4% of vitamin D and 2-4% of vitamin E.

[0006] Further, glucose 60%, rosemary 18%, ferrous sulfate 4%, zinc sulfate 3%, calcium hydrogen phosphate 2%, calcium carbonate 3%, vitamin A 3%, vitamin D 4%, vitamin E 3%.

[0007] Further, glucose 54%, rosemary 20%, ferrous sulfate 6%, zinc sulfate 3%, calcium hydrogen phosphate 2%, calcium carbonate 3%, vitamin A 4%, vitamin D 4%, vitamin E 4%.

[0008] Furthermore, 1 to 2 g of the additive is added to every 2000 g of laying hen feed.

[0009] The preparation method of the laying hen feed additive containing rosemary of the present invention comprises the following steps:

[0010] Step (1): collecting rosemary as raw material, washing with clean water, placing in a cool place, hanging to dry, vacuum sealing, and storing below 0°C;

[0011] Step (2): grinding the rosemary in step (1) to obtain rosemary powder with an average particle size of less than 26 μm;

[0012] Step (3): weighing glucose, rosemary, ferrous sulfate, zinc sulfate, calcium hydrogen phosphate, calcium carbonate, vitamin A, vitamin D, and vitamin E according to weight for later use;

[0013] Step (4): Add the components in step (3) into a mixing mixer and mix thoroughly to obtain a laying hen feed additive, which is then weighed, bagged and sealed.

[0014] Furthermore, the pulverizing step in step (2) uses a low-temperature freezing ultrafine pulverizer, and the processing temperature is lower than 0°C.

[0015] Furthermore, the laying hen feed prepared in step (4) is contained in sealed bags of 1g, 2g, 5g, and 10g specifications, respectively.

[0016] Beneficial effects of the rosemary-containing laying hen feed additive and the preparation method thereof:

[0017] 1. The rosemary-containing laying hen feed additive of the present invention and the preparation method thereof can improve the hatchability, production performance of laying hens, egg production, total egg weight and feed conversion rate by adding the rosemary extract; and the rosemary extract can improve the oxidative stability of eggs when stored at room temperature.

[0018] 2. The rosemary-containing laying hen feed additive of the present invention and the preparation method thereof are added with glucose to provide energy for laying hens, ferrous sulfate, zinc sulfate, calcium hydrogen phosphate and calcium carbonate to improve the absorption of phosphorus by laying hens and prevent the occurrence of cartilage and osteoporosis in livestock and poultry, and vitamin A, vitamin D and vitamin E are added to enhance immunity, promote growth, be easy to absorb, resist heat stress, and increase egg production while ensuring balanced nutrition of laying hens.
