Description

Technical Field

[0001] This application relates to the field of piglet feed additive technology, specifically to plant-based additives for piglet feed, piglet feed, piglet milk powder, and their applications. Background Technology

[0002] The African swine fever outbreak has prompted large-scale pig farms to strengthen and improve biosecurity measures, including breed selection and production model improvements. This has led to an increasing number of large-scale breeding sow farms adopting batch production models, which effectively reduces the risk of cross-contamination between batches of sows and increases sow reproductive turnover, creating a "high-yield, high-culling" production rhythm. Simultaneously, the continuous improvement of sow productivity and the control of maximum nutritional costs on pig farms have resulted in an increase in the proportion of low-birth-weight (B-grade) piglets (weak piglets), insufficient milk production from lactating sows, and a shortage of contract sows. Therefore, improving overall piglet survival rate and weaning weight has become a key factor limiting the profitability of pig farming.

[0003] Currently, pig farms mainly use creep feed to raise weak piglets. Creep feed is a formula system mainly composed of grains, soybean products, and some dairy products, which has deficiencies in the digestion, absorption, and growth of weak piglets. Weak piglets have fragile intestinal function, and intestinal health problems have a significant impact on piglet survival rate, weaning weight, and subsequent healthy development.

The attractant includes a frankincense and a sweetener, wherein the frankincense contains ≥2.0% Γ-nonanolactone and ≥1.5% ethyl vanillin; the sweetener contains 40% to 50% sodium saccharin and sematriol by mass.

[0015] The fourth aspect of this application provides the application of piglet milk powder feed in feeding piglets, including:

[0016] Piglets can be fed directly with piglet milk powder feed, or piglet milk powder feed can be mixed with creep feed at a mass ratio of 1:7-9 and then fed to piglets.

[0017] Beneficial effects:

[0018] The plant additive in the piglet feed of the first aspect of this application uses a combination of Eucommia ulmoides leaf extract and orange peel extract, which can effectively inhibit the reproduction of Escherichia coli and Salmonella, which are pathogenic bacteria in the piglet intestine. The plant additive has anti-inflammatory and antibacterial effects on the piglet intestine, which is beneficial to maintaining the intestinal health of piglets, ensuring the absorption of nutrients from feed after piglets eat, and improving the survival rate and weaning weight of piglets.

[0019] The piglet feed provided in the second aspect of this application contains the plant-based additives found in the piglet feed of the first aspect of this application. Feeding piglets with the piglet feed provided in the second aspect can effectively protect the intestinal health of piglets, improve the absorption of nutrients in the feed, and promote the survival and development of piglets.

[0020] The piglet milk powder provided in the third aspect of this application contains the plant-based additives of the piglet feed of the first aspect of this application and adds surfactants, including sodium citrate and xanthan gum, to increase the uniformity of the feed mixture. After being mixed with water, the piglet milk powder enhances the solubility of organic substances such as proteins, fats, and sugars in water, preventing stratification. The piglet milk powder does not stick to the feed container after mixing with water, therefore it can be transported to the feed troughs via large-scale pipelines in the feeding farm after mixing, avoiding adhesion to pipelines and feed troughs while achieving efficient feed transportation, saving labor costs compared to the current practice of mixing feed only in pig farms. The piglet milk powder provided in the third aspect of this application can effectively inhibit pathogenic bacteria in the piglet's intestines, playing an anti-inflammatory and antibacterial role, effectively ensuring the intestinal health of piglets, promoting nutrient absorption, and ensuring the survival rate and weaning weight of piglets.

[0021] The application of the piglet milk powder feed provided in the fourth aspect of this application in feeding piglets helps improve the intestinal health of piglets and ensures the survival rate and weaning weight of piglets. Attached Figure Description

[0067] II. Testing Section

[0068] 2.1 Antibacterial zone test;

[0069] Test Procedure

[0070] Step 1: Reviving frozen bacterial culture

[0071] Add 10 ml TSB to a 15 ml sterile centrifuge tube, take out the frozen E. coli and Salmonella (CICC) culture from the -80℃ freezer, thaw at room temperature, inoculate into the culture medium, and incubate overnight in a 37℃ vertical incubator before conducting the experiment.

[0072] Step 2: Sample Preparation

[0073] According to the above formula, add 0.5g of plant extract / 0.5ml of sterile physiological saline + 4.5ml of dimethyl sulfoxide (DMSO) to a 10ml sterile centrifuge tube, dissolve and mix thoroughly to obtain a 10% concentration, store at 4℃ for later use, and extract the supernatant of the suspension for testing. Among them, the plant extracts are pure Eucommia ulmoides extract, pure orange peel extract, and a mixed plant extract containing Eucommia ulmoides extract and orange peel extract of the same mass. Three samples were prepared based on different plant extracts.

[0074] Step 3: ZOI Experiment

[0075] Dilute the revived bacterial strain (0.3 ml bacterial suspension + 10 ml physiological saline), and spread 0.2 ml of the diluted bacterial suspension onto MH plates. Use a 1 ml sterile pipette tip to make 3 wells per plate. Use a sterile syringe needle to remove the culture medium from the wells and add 0.075 ml of diluted sample (10% dilution) to each well. Place the plate in a 37℃ vertical incubator and incubate overnight for 17 h. Remove the plate and observe the results by measuring the diameter of the inhibition zone with vernier calipers (rounded to the nearest whole number, in mm).

[0076] The average values ​​of the inhibition zone test results are shown in Table 1 below:

[0077]

[0078] The inhibition zone experiment results demonstrated that, with the same amount of precursor added, single Eucommia ulmoides leaf extract, single orange peel extract, and the plant extract combined with Eucommia ulmoides leaf extract and orange peel extract in the embodiments of this application all exhibited good antibacterial effects against pathogenic bacteria (Escherichia coli and Salmonella). The plant extract combined with Eucommia ulmoides leaf extract and orange peel extract showed stronger antibacterial effects against Shiga toxin-producing Escherichia coli STEC, enteroinvasive Escherichia coli EIEC, Salmonella typhimurium 21484, Salmonella enterica subspecies cholerae serotype 21493, and Salmonella enterica subspecies enteritis serotype 21513 than either Eucommia ulmoides leaf extract or orange peel extract alone. The combination of Eucommia ulmoides leaf extract and orange peel extract in this application exhibits a strong synergistic antibacterial effect, which can inhibit the proliferation of pathogenic bacteria in the intestines of piglets, thus protecting the intestinal health of piglets and promoting their growth and development.

[0079] 2.2 Water solubility test

[0080] 2.2.1 First water solubility test

[0081] Step 1: Weigh 5 grams of piglet milk powder from Example 1 of this application and place it in a 50ml centrifuge tube. Measure 40ml of tap water with a graduated cylinder and add it to the centrifuge tube. Cover the tube and shake it by hand for 2 minutes to allow the piglet milk powder to fully dissolve in the water. Then place it on a stationary rack and observe the water solubility test of the piglet milk powder.

[0082] Step 2: Record the water solubility of piglet milk powder at 1 hour, 2 hours, 4 hours, and 24 hours. After 24 hours, pour out the water solution and observe the residue left on the container. Statistical analysis of the results.

[0083] Result 1: As Figure 1 and Figure 2 As shown, the piglet milk powder of Example 1 of this application did not undergo gradation or stratification after being dissolved in water for 2 hours and 24 hours, indicating that the piglet milk powder has good water solubility.

[0084] Result 2: such as Figure 3 and Figure 4 As shown, 1 part piglet milk powder feed and 8 parts water are mixed, left to stand for 24 hours, then the liquid in the test tube is poured out. The test tube is then inverted to observe the residue at the bottom and on the side walls. This is compared to commercially available competing products. Figure 3 From left to right, the first and second test tubes are piglet milk powder feed from the embodiments of this application, and the second and third test tubes are the first commercially available piglet milk powder feed and the second commercially available piglet milk powder feed, respectively. Figure 4Counting from left to right, the first and second test tubes show the state of the first and second commercially available piglet milk powder after being dissolved in water and left to stand, and then emptied. The third and fourth test tubes show the state of the piglet milk powder in this embodiment after being dissolved in water and left to stand, and then emptied. The piglet milk powder in this embodiment does not separate or grade after 24 hours, does not stick to the wall, and has better water solubility than commercially available piglet milk powder. It does not stick to the wall, thus avoiding clogging of the feeding pipes and improving the efficiency of feeding piglets in actual farms.

[0085] 2.3 Experiment on picky eating:

[0086] The purpose of this experiment was to evaluate the effect of different piglet milk powder feeds on feed preference in piglets. Six litters of weaned piglets around 35 days of age were used, with consistent litter size and number of piglets per litter. Two feed troughs were placed in each litter, with two different types of piglet milk powder feed added to each trough (the piglet milk powder feed from Example 1 of this application and a commercially available control piglet milk powder feed). Feeding was done in dry powder form, with frequent small feedings. The experiment lasted for 7 days. Daily feed consumption per trough for each litter was recorded, and the total feed intake of each type of piglet milk powder feed during the experiment was calculated. The results showed that: 1. When fed the two types of piglet milk powder feeds, 76% of piglets chose to eat the piglet milk powder feed from Example 1 of this application, 15% chose to eat the control piglet milk powder feed, and 9% did not choose it; 2. During the experiment, the total feed intake of the piglet milk powder feed from Example 1 of this application was 10 kg, while the total feed intake of the control piglet milk powder feed was 8.25 kg.

[0087] This demonstrates that the piglet milk powder provided in the embodiments of this application has good palatability, and the piglets show obvious preference for the piglet milk powder provided in the embodiments of this application.

[0088] 2.4 Comparison of feeding speed and time

[0089] Three pens of piglets were set up, each fed a different piglet formula. The first pen was fed the imported product PIGIPRO, the second pen the imported product OPTICARE, and the third pen the piglet formula (i.e., BABYCARE) from Example 1 of this application. Each pen contained 26 piglets, and 1.5 kg of feed was given to each piglet simultaneously. The time it took to finish feeding was recorded. Figure 5 ,from Figure 5 It can be seen that, for the same weight of feed, the piglets consume the piglet milk powder feed in the embodiment of this application in the shortest time, proving that the piglet milk powder feed provided in this application can provide piglets with strong digestive capacity and high feeding efficiency, thereby shortening the feeding time.

[0090] 2.5 Animal Experiments

[0091] Compared with imported products: the piglet milk powder feed of this application embodiment showed significantly better litter weight gain, average daily feed intake, diarrhea rate, and mortality rate than imported products. Table 2 below shows the feeding methods for suckling piglets and early-weaned piglets in this animal experiment.

[0092] Table 2

[0093]

[0094] Notes: 1. All wet feed should be consumed within 2 hours, otherwise it should be discarded. 2. For the first three stages, the formula should be mixed with warm water at around 50℃.

[0095] In this experiment, all experimental conditions were the same except for the type of piglet milk powder feed used to feed the piglets. The results are shown in Table 3 below:

[0096] Sow with piglets experiment

[0097]

[0098]

[0099] Table 2 shows that in the sow-piglet trial, the mortality rate of piglets fed with the method described in this application was lower than that of piglets fed with commercially available imported piglet milk powder feed. The litter weight gain was significant, and the diarrhea rate was significantly reduced, which is beneficial to improving the survival rate and growth and development of piglets.
