Description

Technical Field

[0001] The invention belongs to the technical field of fattening cattle feed preparation, and specifically refers to fattening cattle feed for improving lean meat rate and a preparation method thereof. Background Art

[0002] Beef is rich in protein, amino acids, trace elements and other ingredients, and has extremely high nutritional value. It has become one of the common meats consumed by consumers. The gradual increase in beef consumption has driven the development of the breeding industry.

[0003] As people's living standards improve, the demand for beef is growing, especially for beef with high lean meat rate and tender meat. In the process of fattening cattle breeding, traditional feed is often difficult to meet the requirements of rapid body shape, oil control and increasing lean meat rate at the same time. There are some shortcomings in the fattening cattle feed on the current market, such as unbalanced nutrients, easy to cause excessive fat deposition in cattle, and unsatisfactory growth rate.

[0004] In order to meet market demand and improve the economic benefits of fattening cattle breeding, it is of great practical significance to develop a fattening cattle feed and a preparation method thereof that can effectively increase the lean meat rate, control fat accumulation and promote rapid growth of cattle. Summary of the invention

[0005] In order to solve the above-mentioned problems, the present invention provides a fattening cattle feed with improved lean meat rate and a preparation method thereof.

[0006] In order to achieve the above functions, the technical scheme adopted by the present invention is as follows: a fattening cattle feed for improving lean meat rate, wherein the formula composition by weight is: 20-30 parts of soybean meal, 10-15 parts of fish meal, 30-40 parts of corn, 10-15 parts of wheat bran, 10-15 parts of alfalfa meal, 5-10 parts of rapeseed meal, 0.5-1 parts of probiotics, 0.5-1 parts of amino acid chelate, 0.3-0.8 parts of enzyme preparation, 0.2-0.5 parts of lotus leaf extract, 0.2-0.5 parts of hawthorn extract, and 0.2-0.5 parts of green tea extract.

[0007] Preferably, the corn is selected to be full-grained, mold-free and matured; the soybean meal is selected to be high in protein content and low in anti-nutritional factors; the fish meal is selected to be fresh and odorless; and the rapeseed meal is selected to be detoxified.

[0008] The present invention also discloses a method for preparing a fattening cattle feed for improving lean meat rate, comprising the following steps:

[0009] (i) Raw material pretreatment: crush soybean meal, corn, wheat bran, rapeseed meal and other raw materials into a particle size of 2-3 mm using a crusher, and dry the fish meal to remove moisture at a temperature of 60-80°C for 2-3 hours;

[0010] (ii) Mixing and stirring: Add the pretreated raw materials and fish meal into a double-shaft paddle mixer and stir for 15-20 minutes at a stirring speed of 30-40 r / min. During the stirring process, gradually add alfalfa powder, probiotics, amino acid chelate, enzyme preparation, lotus leaf extract, hawthorn extract and green tea extract, stir well and ensure that they are evenly distributed in the feed;

[0011] (III) Granulation: The mixed feed obtained in step (IV) is granulated by a granulator at a granulation temperature of 70-80°C and a pressure of 10-15 MPa. The feed particles after granulation are 4-6

[0012] mm;

[0013] (IV) Cooling and packaging: The pelletized feed is cooled to room temperature and packaged after removing excess heat and moisture.

[0014] Preferably, the probiotics in step (ii) are one or a mixture of lactic acid bacteria, bacillus or yeast.

[0015] Compared with the prior art, the present invention adopts the above solution to achieve the following beneficial effects:

[0016] 1. The present invention provides sufficient amino acids for fattening cattle through soybean meal and fish meal to promote muscle growth. Soybean meal has been specially treated to remove anti-nutritional factors and improve protein utilization; fish meal is rich in high-quality animal protein and unsaturated fatty acids, which helps to improve the palatability and nutritional value of feed; corn has been crushed and cooked to improve digestibility; wheat bran is rich in dietary fiber, which helps to regulate the intestinal function of cattle; alfalfa meal is rich in high-quality protein and multiple vitamins and minerals, which can provide rich nutrition for fattening cattle; rapeseed meal has a high protein content after detoxification treatment and is relatively low in price, which can effectively reduce feed costs; amino acid chelates can improve the utilization of trace elements and promote muscle growth; lotus leaf extract has the effect of controlling oil and can reduce the deposition of fat in cattle; hawthorn extract can promote digestion, increase appetite, and help the growth of fattening cattle; green tea extract has antioxidant and lipid-lowering effects, which can improve the metabolic function of cattle;

[0017] 2. Through the reasonable combination of protein, energy, natural extracts and other ingredients, it can effectively reduce fat deposition, promote muscle growth, and thus increase the lean meat rate; the combination of various raw materials provides rich nutrients such as protein, vitamins, minerals, etc. to meet the growth needs of fattening cattle; the addition of probiotics and enzyme preparations helps to improve the intestinal flora of cattle and improve the digestion and absorption efficiency of feed; the use of natural hawthorn extract and green tea extract does not contain any banned drugs and hormones, and is safe and environmentally friendly.
