Technical Field
[0001] The invention relates to the technical field of feed processing, in particular to a calf feed additive and a preparation method thereof. Background Art
[0002] Calf breeding is one of the main bodies of my country's animal husbandry industry, so how to improve the survival rate of calf breeding is a problem encountered in current development. Calf generally refers to calves born between 4 and 6 months old. Breeders should pay special attention to the health of calves in these months. The health of calves is related to the economic benefits of the entire calf breeding industry.
[0003] Feed is an important part of calf rearing. How to specifically supplement the nutrition of calves, improve the calf rearing efficiency, increase the rearing income, and reduce the rearing cost is a problem that continues to be solved in the prior art. Summary of the invention
[0004] In order to solve the problems existing in the prior art, the present invention provides a calf feed additive and a preparation method thereof, by adjusting the formula of the additive, the cost of the feed is further reduced while ensuring the quality of the feed. The specific technical scheme is as follows: A calf feed additive is prepared by mixing a mineralized mixture with flour; the mass ratio of the mineralized mixture to the flour is 1:1-6.
[0005] Furthermore, the mineralized mixture is prepared by mixing montmorillonite powder and corn starch in a mass ratio of 1:1.
[0006] Furthermore, the montmorillonite powder has a fineness of 800-900 mesh.
[0007] Furthermore, the dosage of the additive is 2-5% of the total mass of the feed.
[0008] Furthermore, the flour is short-grained wheat flour.

[0011] The technical solution of the present invention is further defined below in conjunction with specific implementation methods, but the scope of protection required is not limited to the description.
[0012] Example 1 A calf feed additive, the additive is formed by mixing a mineralized mixture with flour; the mass ratio of the mineralized mixture to the flour is 1:1; the mineralized mixture is formed by mixing montmorillonite powder and corn starch in a mass ratio of 1:1; the fineness of the montmorillonite powder is 800 mesh; the dosage of the additive is 2% of the total mass of the feed.
[0013] The preparation method of the calf feed additive comprises the following steps: weighing various raw material components, firstly mixing montmorillonite powder with corn starch, then adding flour, and mixing them evenly in a mixer.
[0014] According to this embodiment, the feed additive is prepared and its technical indicators are tested. The specific operations are as follows: (1) Purpose of this study: By setting different addition gradients of montmorillonite and starch, we seek the best addition ratio with wheat bran flour containing starch, and strive to minimize the use of wheat bran flour containing starch adhesives, thereby optimizing the formula, reducing the formula cost and improving the feed-to-meat ratio while ensuring the strength of feed particles and an acceptable powder content.
[0015] The current formula for calf concentrate supplements is: 51% corn; 8% flour; 11% soybean meal; 6% sprayed corn husks; 4% corn germ meal; and 1% molasses.
[0016] (2) Basic information of the test: Trial time: October 2023 Trial location: Guizhou Modern Biotechnology Co., Ltd. Equipment process parameters: Ring die compression ratio is 1:9 Adding method: manual weighing, adding through small feed port Mixer parameters: 3 tons / batch, capable of spraying grease and molasses.
[0017] Conditioner moisture: see below Figure 1 , the effect of adding montmorillonite and a-starch mixture on feed moisture.
[0018] (3) Experimental group design and requirements: The design of the mixture test group is shown in the table above. By setting different addition amounts of the mixture and adjusting the amount of flour used, other nutrients are supplemented with sprayed corn husks, corn germ meal, and molasses to make the nutritional components of the formula consistent with the blank control. The results are shown in the attached Figure 2 . Under the same process line and the same process parameters, the powder content and hardness index of feed additives were tested.
[0019] Test personnel: Biotechnology production technology director, some personnel from the production department and quality control department, and other related operators; Division of work: The production department and the quality control department jointly formulate the test plan; at the same time, arrange workers in related positions to cooperate with the test, jointly take samples, break bags, and then measure the powder content, hardness value, and moisture.
[0020] (4) Collection of test data: Hardness value, moisture content: Each group of samples is continuously taken during the feeding process (the feeding point is the packaging station) until the test of this group is completed, and then the next group of samples is taken. The samples are marked and sealed. At the same time, a bag (40 kg) of calf feed from this group is randomly selected and left for 24 hours for powder content and hardness value test.
[0021] Powder content (powderization rate): let a bag (40 kg) of calf feed fall freely on the ground from a height of 0.5m, repeat 3 times, change to the other side and drop it 3 times, sieve with a 60-mesh sieve, weigh the amount of powder under the sieve (kg), calculate the powder content (%), and perform data analysis.
[0022] The powder content is shown in the following table: Particle hardness value (the samples taken from the workshop are divided by a divider, one part is crushed for nutrient analysis, and the other part is randomly selected with the same particle length for particle hardness test). The effect of the mixture on particle hardness is shown in the following table: The cost changes of using mixture to replace flour formula, and the economic benefit analysis after adding mixture are as follows: In summary, after adding the mixture, the hardness values of the experimental groups were basically the same as the original formula (the hardness value of the control group was 5.44, the hardness value of the 10 kg mixture was 5.47, and the hardness value of the 20 kg mixture was 5.26), and the powder content was slightly increased, with no significant difference, within the acceptable value of 0.4% (the control group was 0.00, the 10 kg mixture was 0.00, and the 20 kg mixture was 0.30%). On the premise of maintaining the particle strength and acceptable powder content, the addition of 20 kg of the mixture group can significantly reduce the ton formula cost (12.27 yuan / ton). Based on the annual production of 20,000 tons of calf feed, the annual cost can be saved by nearly 250,000 yuan. The hardness of the particles added to the mixture is related to the addition of molasses. The water in the molasses added by the mixer is free water, which only adheres to the surface of the material particles, which is not conducive to the gelatinization of starch in the feed in the later stage to make the particles form. The temperature of the conditioner is low (about 75°C), which has a slight effect on the function of the mixture. If the temperature of the conditioner can be increased, better data results will be obtained.
[0023] Example 2 A calf feed additive, which is formed by mixing a mineralized mixture with flour; the mass ratio of the mineralized mixture to the flour is 1:1. Furthermore, the mineralized mixture is formed by mixing montmorillonite powder and corn starch in a mass ratio of 1:1; the fineness of the montmorillonite powder is 800-900 mesh; the amount of the additive is 5% of the total mass of the feed; and the flour is wheat flour. In order to enhance the nutritional effect, the method for preparing montmorillonite powder is as follows: processing the montmorillonite into a powder with a particle size of 1-3mm, calcining at 200-300°C for 2-5h, lowering the temperature to 50-60°C, mixing and pulping pumpkin with 1-1.5 times the mass of the powder, grinding the pulp for 3-5 times, adding the aforementioned powder and mixing with the slurry evenly, inoculating yeast powder, and fermenting at 26-28°C for 30-40min; Sodium selenate, yttrium nitrate and bone powder are added to the fermented product, the mixture is heated to 30-33°C, the fermentation is continued for 20-30 hours, purified water is added to dilute the fermented product by 2-3 times, the fermentation is continued for 50-70 minutes, the precipitate is dried, crushed into powder of 600-800 mesh, starch adsorbent and Chinese herbal medicine are added to obtain montmorillonite powder; the filtrate is reserved for later use; The amount of yeast used is 6-7% of the mass of the slurry; the amount of sodium selenate used is 1-3% of the mass of the slurry; the amount of yttrium nitrate used is 0.3-0.5% of the mass of the slurry; the amount of bone powder used is 10-13 of the mass of the slurry; the starch adsorbent is made of sprayed corn husk, corn germ meal and molasses in a mass ratio of 5:7:0.2-0.23; the preparation method of Chinese herbal medicine is as follows: 5-8 parts of Forsythia suspensa, 3-7 parts of Phellodendron amurense, 1-2 parts of Honeysuckle, 9-15 parts of Ziziphus jujuba and 8-10 parts of Crataegus pinnatifida are processed into powder of 400-500 mesh.
[0024] According to this implementation, feed additives were made and used in calf feeding as an experimental group; the comparison group did not use the additives of this embodiment, and used the commercially available Zhuhai Weinuo Breeding Co., Ltd.'s multidimensional feed additives. The experimental calves were 50 newborn local yellow cattle calves, randomly divided into groups, and after feeding breast milk for 4 weeks, they weighed 31.21-33.67 kg, all in good health, and each group was raised separately for 30 consecutive days. After the experiment, the average weight gain of the experimental group was 58.96 kg, and the average weight gain of the control group was 44.62 kg; during the entire experiment, only 2 cows in the experimental group had diarrhea and returned to normal, and 3 cows in the control group had diarrhea and 2 cows had limp limbs, all of which had been treated and recovered. It can be seen that the use of the feed additives of the present invention can promote calf nutrition accumulation, rapid growth, and improve calf immunity.
