Description

Technical Field

[0001] The invention relates to the technical field of feed, in particular to a compound feed for promoting the growth and development of meat pigeons and a preparation method thereof. Background Art

[0002] In the field of pigeon farming, compound feed is the key to achieving efficient fattening and healthy growth. In the prior art, conventional pigeon feed is mostly formulated based on energy raw materials, vegetable oils and fats, protein supplements and conventional additives (vitamins, mineral premixes). In order to improve energy density and essential fatty acid supply, some feeds directly add animal fat as an energy source. However, this conventional method has significant mechanistic deficiencies.

[0003] First, directly added butter, due to its high melting point and high proportion of saturated fatty acids, has poor digestion and absorption efficiency in pigeons. Butter's stable molecular structure makes it poorly compatible with other feed components, making it difficult to form a uniformly dispersed emulsion. This limits the effective contact area for lipase, reducing fat hydrolysis efficiency and energy utilization. Inadequately digested and absorbed fat not only wastes energy but also increases intestinal burden, impairing the absorption of other nutrients.

[0004] Secondly, amino acid supplements in current feeds are often added directly in free form. Free amino acids are rapidly absorbed in the gastrointestinal tract, but may be relatively independent of the metabolic pathways of the fat component of the feed, lacking synergistic effects. Amino acids that fail to form an effective bond with fat have room for improvement in bioavailability, limiting their ability to promote protein synthesis and muscle growth.

[0005] Furthermore, existing technologies for combining oils and functional carriers often remain at the physical mixing level, failing to further modify the oil's physical and chemical properties to enhance its functionality. While diatomaceous earth is used as an adsorbent or carrier, conventional processing methods fail to fully exploit its porous structure and surface activity for oil modification.

[0006] Therefore, there is an urgent need to develop a new type of compound feed, the core of which is to improve the bioavailability of key components through innovative modification technology and promote the synergistic metabolism between different nutrients, so as to break through the mechanism bottleneck of existing feed in promoting the efficient growth and development of meat pigeons. Summary of the Invention

[0007] The present invention provides a compound feed for promoting the growth and development of meat pigeons. The utilization rate of butter and amino acids is improved by using a butter-modified additive, and the absorption of other nutrients is promoted, thereby providing sufficient raw materials for protein synthesis and body growth. On the other hand, diatomaceous earth is used as a carrier to absorb harmful substances such as mold, bacteria and excessive ammonia, thereby reducing the intestinal burden of meat pigeons and the risk of intestinal inflammation.

[0008] Based on this, it is necessary to provide a compound feed that promotes the growth and development of meat pigeons, the raw materials including the following components by mass:

[0009]

[0010]

[0011] The tallow modified additive is a product obtained by mixing tallow and amino acids and reacting them with diatomaceous earth after ultrasonic heating.

[0012] Furthermore, the amino acid is selected from one or more of lysine, tryptophan, methionine and threonine.

[0013] Furthermore, the vegetable oil is at least one of peanut oil, soybean oil, rapeseed oil and sunflower oil.

[0014] Furthermore, the auxiliary agent is selected from one or more of stone powder, salt, zeolite powder, vitamins, and minerals.

[0015] Furthermore, the vitamin is selected from one or more of vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin H, vitamin K, folic acid, niacin, calcium pantothenate, inositol and choline.

[0016] Furthermore, the mineral is selected from one or more of sodium chloride, cobalt chloride, magnesium sulfate, zinc sulfate, copper sulfate, iron sulfate, sodium phosphate, potassium phosphate, calcium phosphate and potassium iodate.

[0017] Furthermore, the particle size of the stone powder is 100-400 mesh.

[0018] The present invention also provides a method for preparing the compound feed for promoting the growth and development of meat pigeons, comprising the following steps:

[0019] S1, mixing sulfuric acid solution with diatomaceous earth, and heating to obtain acid-washed diatomaceous earth;

[0020] S2, mixing tallow, amino acid and acid-washed diatomaceous earth, and ultrasonically heating to obtain a tallow modified additive;

[0021] S3. Evenly mix the modified butter additive with other ingredients to obtain a compound feed for promoting the growth and development of meat pigeons.

[0022] Furthermore, in step S1, the pretreatment step is: soaking the pearl shell powder in a sodium hydroxide solution and then performing ball milling treatment.

[0023] Furthermore, in step S1, the heating temperature is 50-60°C;

[0024] In step S2, the heating temperature is 70-80°C.

[0025] Specifically, the acid treatment of the diatomaceous earth after the pickling can increase the specific surface area and pore volume of the diatomaceous earth, making the pores more unobstructed and developed, and the diatomaceous earth surface has more active sites. In subsequent treatments, the number of active groups on the diatomaceous earth surface can be increased, thereby enhancing its adsorption capacity. On the one hand, as a carrier, it may protect the active substances generated by the reaction through adsorption, and achieve a certain degree of sustained release in the digestive tract, reducing nutritional losses. On the other hand, diatomaceous earth itself has good adsorption properties, and can adsorb some harmful substances and excess water in the intestine, which helps to maintain the stability of the intestinal environment and reduce intestinal stress and inflammatory reactions.

[0026] The present invention has the following beneficial effects:

[0027] The compound feed for promoting the growth and development of meat pigeons of the present invention is compounded with corn flour, wheat flour, vegetable oil and tallow additives. First, diatomaceous earth is pickled with a sulfuric acid solution, then mixed with tallow and amino acids, and heated for reaction, thereby introducing the tallow and amino acids into the diatomaceous earth to obtain the tallow-modified additive.

[0028] Because butter contains a large amount of fatty acids, after mixing with amino acids, the carboxyl groups in the two can react with the surface active hydroxyl groups of diatomaceous earth, and the rich porous structure of diatomaceous earth can load butter and amino acids. The three form a stable complex. While diatomaceous earth absorbs harmful substances such as mold, bacteria and excessive ammonia, it reduces the burden on the intestines of meat pigeons and the risk of intestinal inflammation, while providing more nutrition and active substances, and promoting the absorption of corn flour and wheat flour, thereby improving absorption efficiency and more accurately meeting the needs of tissue protein synthesis.

[0029] Moreover, beef tallow can provide sufficient energy for pigeons to consume, reducing the decomposition of protein as an energy source, allowing more amino acids to be used for the synthesis of muscle and other tissues. This provides a good growth and development environment for pigeons, increasing their meat production. In summary, the compound feed of the present invention can not only improve the feed digestibility of pigeons, but also promote the growth and development of pigeons, ensuring the healthy growth of pigeons.
