Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry, and particularly relates to talcum powder for piglets and a preparation method thereof. Background Art

[0002] In the field of animal husbandry, talcum powder is mainly designed for newborn piglets and is used in the delivery and nursing stages. The main purpose of using talcum powder for piglets is to keep warm, improve the environment, reduce inflammation and stop bleeding, and improve the survival rate. Talcum powder has super strong adsorption and drying functions, which can keep the piglet's body surface dry and comfortable, effectively maintain normal body temperature, and prevent hypothermia caused by moisture on the body surface. Talcum powder can remove the ammonia smell in the pig house, absorb moisture, reduce the reproduction of bacteria, fungi and parasite eggs, thereby reducing the incidence of respiratory diseases, diarrhea and piglet diseases. For newborn piglets, talcum powder can speed up the drying, healing and shedding process of the umbilical cord, reduce the risk of bacterial infection, and has anti-inflammatory and analgesic effects. Talcum powder helps to improve the survival rate of piglets by keeping the piglet's body surface dry and reducing digestive tract infections.

[0003] The adhesion of talcum powder is crucial for its application on the piglet's body surface. Talcum powder with good adhesion can fit tightly to the piglet's skin and is not easy to fall off, thus more effectively exerting its heat preservation, drying and antibacterial effects; lower adhesion will cause the talcum powder to scatter during use, and it is not easy to form a uniform covering layer on the piglet's body surface, affecting the use effect.

[0004] Water absorption is an important indicator to measure the drying performance of talcum powder. Talcum powder with a high water absorption rate can quickly absorb moisture and humidity from the piglet's body surface, keep the piglet's body surface dry, help maintain normal body temperature, and prevent diseases caused by moisture on the body surface; talcum powder with insufficient water absorption may not be able to effectively absorb moisture from the piglet's body surface, causing the piglet's body surface to remain moist and increase the risk of disease. However, if the water absorption rate of talcum powder is too high, it may excessively absorb moisture from the piglet's skin surface, causing the skin to become too dry. Dry skin is prone to itching, redness, and desquamation, causing discomfort to the piglet. The piglet's skin is its first barrier against external pathogens and harmful substances. Excessive water absorption may destroy the skin's natural oil balance, weaken the skin's barrier function, and make the piglet more susceptible to infection and other skin problems. In addition, talcum powder with too high a water absorption rate may quickly clump or become sticky when used, and it is not easy to evenly apply it on the piglet's body surface, which will not only affect the use effect, but also may cause operational inconvenience to the breeder.

[0005] The pH value of talcum powder has an important impact on its safety when used on the piglet's body surface. Talcum powder with a pH value close to that of piglet's skin (usually neutral or close to neutral) can reduce irritation and damage to the skin and ensure its safety. Talcum powder with a pH value that is too high or too low can irritate the piglet's skin, causing problems such as redness and itching, and even cause skin inflammation.

[0006] The antibacterial properties of talcum powder are of great significance for preventing piglet infections. Talcum powder with good antibacterial properties can inhibit the reproduction of bacteria on the surface of piglets, reduce the risk of infection, and help maintain the health of piglets; talcum powder with insufficient antibacterial properties cannot effectively inhibit the reproduction of bacteria, resulting in an increased risk of piglet infection.

[0007] In summary, adhesion, water absorption rate, pH value and antibacterial performance are key indicators for evaluating the performance of talcum powder for piglets. The existing talcum powder for piglets has the problems of excessively high water absorption rate (94.3%), high pH rate, and no antibacterial effect on common harmful bacteria (Escherichia coli, Salmonella, Staphylococcus aureus). The field is in urgent need of a talcum powder for piglets that has good adhesion, appropriate water absorption rate, mild pH value and strong antibacterial performance. Summary of the invention

[0038] The raw materials required for the embodiments of the present invention are all purchased from the market.

[0039] In order to more clearly understand the shortcomings of the existing talcum powder for piglets and to provide a talcum powder for piglets with better performance, the present invention conducted the following research on the existing talcum powder for piglets on the market (Salcum feed additive purchased from Chifeng Hemeijia Technology Co., Ltd.):

[0040] 1. Sensory evaluation of competing piglet talcum powder on the market:

[0041] The competing products on the market have a fresh fragrance. Figure 1 This is a real photo of a competing product on the market. Figure 1 It can be seen that the color of the competitor's product is earthy gray.

[0042] 2. Determination of water absorption

[0043] Spread the competitive product on the market in a sample basin (8cm-10cm thick), use a pipette (20mL) to absorb 20mL of 1wt.% sodium chloride solution at a temperature of 36℃-40℃, and transfer it to an acid burette (25m). Adjust the acid burette to about 3cm away from the sample plane, open the acid burette, and allow the solution to flow into the sample within 30s. After all the solution flows out for 60s, take out the agglomerated sample and weigh the mass m on a balance with a sensitivity of 0.01g (sensitivity of 0.01g). According to this method, make 3 groups of samples at the same time and calculate the average value. The measurement result is 94.3%.

[0044] The calculation formula of water absorption result is: X = 20 / (m-20) × 100%;

[0045] Where: X-water absorption (%), m-agglomeration weight, unit is g.

[0046] 3. Adhesion test

[0047] Place white paper on the electronic balance and reset it to zero. Weigh the competitive product, montmorillonite, and zeolite powder (i.e., m1) on the back of your hand and spread them evenly. Place the back of your hand on the reset electronic balance and tilt it 90°. After staying for 3 seconds, weigh the weight of the fallen sample m2. The one with the heaviest m2 has the worst adhesion. The test results are shown in Table 1 Figure 2 This is a diagram illustrating the adhesion measurement method. The results show that in terms of adhesion, montmorillonite > commercially available competitors > zeolite powder.

[0048] Table 1

[0049] Initial weight(g) Final weight(g) Proportion Adhesion rate Competitive products on the market 0.2621 0.1098 41.89％ 58.11％ Montmorillonite 0.2257 0.0293 12.89％ 87.02％ Zeolite powder 0.2259 0.1100 48.69％ 51.31％

[0050] 4. pH determination

[0051] Table 2

[0052]

[0053] It can be seen from Table 2 that the pH of competing products on the market is alkaline, which can neutralize the acidic substances in body secretions, while the pH of montmorillonite and zeolite powder, the core ingredients of talcum powder, is relatively high, and the pH of talcum powder can be adjusted to a weak alkaline state by adding a small amount of boric acid.

[0054] 5. Antibacterial Verification

[0055] The antibacterial performance test of the present invention adopts conventional testing methods, which will not be elaborated in detail. The results show that boric acid has a certain antibacterial effect on Escherichia coli, while commercially available competitive products and montmorillonite have no antibacterial effect on Escherichia coli; boric acid has a certain antibacterial effect on Salmonella, while commercially available competitive products and montmorillonite have no antibacterial effect on Salmonella; boric acid has a certain antibacterial effect on Staphylococcus aureus, while commercially available competitive products and montmorillonite have no antibacterial effect on Staphylococcus aureus.

[0056] In summary, the color of the competing products on the market is earthy gray with a refreshing smell; it has the characteristics of water absorption rate (51.12%) and adhesion (adhesion rate 58.11%); the pH is alkaline, and it has no antibacterial effect on common harmful bacteria Escherichia coli, Salmonella, and Staphylococcus aureus. The main core ingredient montmorillonite also has no antibacterial effect. It is speculated that its antibacterial effect is mainly achieved by forming a physical barrier on the animal surface; the particle size is small (the material under the 80-mesh sieve accounts for 99.63%), and obvious white small particles and a small amount of sawdust can be seen on the material above the 80-mesh sieve, and the white small particles are insoluble in water.

[0057] Examples 1-4

[0058] The raw material components of Examples 1-4 were weighed according to Table 3. In Examples 1-3, the particle sizes of montmorillonite, talc and zeolite powder were controlled. Boric acid, calcium citrate and menthol were crushed and sieved. Montmorillonite, talc and zeolite powder were mixed, and menthol was added. After mixing, boric acid and calcium citrate were added to adjust the pH to prepare talcum powder for piglets.

[0059] In Example 4, the particle sizes of montmorillonite, talc and zeolite powder are controlled, boric acid and calcium citrate are crushed and sieved, montmorillonite, talc and zeolite powder are mixed, lavender essential oil is added, boric acid and calcium citrate are added after mixing, and the pH is adjusted to prepare the talcum powder for piglets.

[0060] Table 3

[0061]

[0062] Comparative Examples 1-4

[0063] The raw material components of the comparative examples were weighed according to Table 4, and the particle sizes of montmorillonite, talc and zeolite powder were controlled, and the boric acid, calcium citrate and menthol were crushed and sieved; wherein, the amount of montmorillonite was reduced in comparative example 1, and the amount of zeolite powder and talc powder added was correspondingly increased; the boric acid was removed in comparative example 2, the calcium citrate was removed in comparative example 3, and the menthol was removed in comparative example 4.

[0064] Table 4

[0065]

[0066] Performance test

[0067] 1. Adhesion test

[0068] Adhesion tests were performed on Examples 1-4 and Comparative Examples 1-4, and compared with commercially available competing products (Shuangshenbao feed additive), montmorillonite and zeolite powder. The test results are shown in Table 5.

[0069] Adhesion rate = (m1-m2) / m1;

[0070] Where m1 and m2 are the initial mass and post-test mass of the corresponding sample, respectively.

[0071] Table 5

[0072]

[0073] 2. pH determination

[0074] pH tests were performed on Examples 1-4, Comparative Examples 1-4, commercially available competitive products, montmorillonite and zeolite powder. The results are shown in Table 6.

[0075] Table 6

[0076]

[0077] As can be seen from Table 6, the pH of the competing products on the market is alkaline, which can neutralize the acidic substances in the body secretions. However, the pH of the core ingredients of the talcum powder provided by the present invention, montmorillonite and zeolite powder, is relatively high, and the pH of the talcum powder is adjusted to a weak alkaline state by adding a small amount of boric acid (pH: 3.68). Boric acid and calcium citrate in the talcum powder for piglets provided by the present invention form a buffer system, which adjusts the pH of the talcum powder to neutral and reduces irritation to the piglet's body surface; and reducing the amount of boric acid and calcium citrate will make the pH of the talcum powder alkaline.

[0078] 3. Determination of water absorption

[0079] The water absorption rates of Examples 1-4 and Comparative Examples 1-4 were measured and compared with commercially available competitive products.

[0080] Table 7

[0081]

[0082] It can be seen from Tables 5-7 that removing menthol has no effect on the pH, water absorption rate and adhesion rate of talcum powder, but it will affect the flavor of the product; as the menthol is removed, the flavor becomes lighter.

[0083] It can be seen from 5 and 7 that: since montmorillonite has a stronger adhesion rate and a higher water absorption rate than zeolite powder, reducing the amount of montmorillonite will reduce the water absorption rate and adhesion of talcum powder.

[0084] 4. Antibacterial performance test

[0085] The antibacterial performance of the talcum powder and montmorillonite for piglets prepared in Example 1 and Comparative Examples 1-2 was tested, while water was used as a negative control group and streptomycin was used as a positive control group.

[0086] The antibacterial results using Escherichia coli as the indicator bacteria are shown in Table 8. Figure 3It is a comparison chart of the inhibition zones of talcum powder for piglets, montmorillonite, positive control group and negative control group prepared in Example 1 and Comparative Examples 1-2.

[0087] Table 8

[0088] Bacteria Escherichia coli inhibition zone / mm Negative control (water) 0 Positive control (streptomycin) 25.10 Example 1 13.52 (sensitive) Comparative Example 1 13.31 (sensitive) Comparative Example 2 —— Montmorillonite ——

[0089] It can be seen from Table 8 that the talcum powder for piglets prepared in Example 1 and Comparative Example 1 of the present invention have a certain antibacterial effect on Escherichia coli, while Comparative Example 2 and montmorillonite have no antibacterial effect on Escherichia coli, indicating that the main core component with the antibacterial effect is boric acid.

[0090] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
