[0002] Mare's milk is sweet and cool in nature, clearing heat from the gallbladder and stomach, and can treat various throat and oral ailments. It also has the benefits of nourishing the body, moisturizing and beautifying the skin, and clearing away heat and quenching thirst. From a nutritional perspective, compared to other animal milks, mare's milk is high in lactose, low in fat, and low in protein.

[0003] Fresh mare's milk is purified, concentrated, and spray-dried to produce mare's milk powder, turning liquid milk into milk powder. This facilitates packaging and transportation, extends the shelf life of mare's milk products, and retains the unique nutritional value and health and therapeutic effects of mare's milk. Mare's milk is rich in lactoferrin and lysozyme, unsaturated fatty acids such as linoleic acid and arginine, as well as various immune-related components such as antibodies, suggesting the anti-inflammatory effect of mare's milk. Research by Gulibahar et al. has shown that mare's milk powder has significant antioxidant activity (Gulibahar Kawuli, Gao Xiaoli, Chang Zhanying, et al. Antioxidant activity of fresh mare's milk powder in vivo [J]. Food and Fermentation Industries, 2015, 41(6):134-137).

[0051] Study on the effect of the mare's milk powder nutritional composition of the present invention on spleen deficiency rats 1. Establishment of the rat spleen deficiency model 60 SPF SD rats were randomly selected as blank control groups, and the remaining rats were randomly divided into 9 groups according to the random number method, with 6 rats in each group, namely model control group, Example 1 group (administered 6.45 g / kg of the composition of Example 1), Example 2 group (administered 6.45 g / kg of the composition of Example 2), Example 3 group (administered 6.45 g / kg of the composition of Example 3), Comparative Example 1 group (administered 6.45 g / kg of the composition of Comparative Example 1), Comparative Example 2 group (administered 6.45 g / kg of the composition of Comparative Example 2), Comparative Example 3 group (administered 6.45 g / kg of the composition of Comparative Example 3), Comparative Example 4 group (administered 6.45 g / kg of the composition of Comparative Example 4), and Comparative Example 5 group (administered 6.45 g / kg of the composition of Comparative Example 5).

[0052] A spleen deficiency rat model was established using a combination of "irregular diet and excessive fatigue." Except for the blank control group, rats in all other groups received feed every other day, at double the amount of food (constrained hunger and satiety). The rats were placed in 22°C water and allowed to swim until they "bubbled" five times in a row. This process was repeated twice daily for 21 days.

[0053] The criteria for determining a spleen deficiency model are as follows: loose stools; weight loss or slow weight gain; curling up; listless demeanor and withered fur; hunched back; and easy fatigue. The first three are primary symptoms, and the last three are secondary symptoms. A successful model is established if two primary symptoms and one secondary symptom, or one primary symptom and two secondary symptoms, are met.

[0054] After modeling, the rats in Example 1-3 and Comparative Example 1-5 groups were gavaged with the corresponding compositions. The rats in the blank control group and model control group were gavaged with an equal volume of normal saline at a dose of 10 mL / kg, once a day for 21 consecutive days.

[0055] 2. Index detection 2.1 Determination of urinary D-xylose excretion and amylase (AMS) content After fasting for 12 hours, the rats were gavaged with 3% D-xylose at a dose of 20 mL / kg, and urine was collected for 5 hours. The urinary D-xylose excretion was determined according to the instructions of the D-xylose kit.

[0056] Blood was collected from the venous plexus of the fundus of rats and centrifuged at 3000 r / min for 10 min to obtain serum. The AMS content was determined according to the kit instructions.

[0057] 2.2 Organ Index Rats were anesthetized, and the thymus and spleen were separated, washed with 0.9% sodium chloride solution, dried with filter paper, and weighed. The organ index was calculated.

[0058] Organ index (%) = (organ mass / body mass) × 100%.

[0059] 2.3 Determination of serum immunoglobulin content After the last administration, fast for 12 hours, and draw blood from the fundus venous plexus. Let it stand at room temperature for 1 hour, and centrifuge at 3000 rpm for 10 minutes to collect the supernatant. Follow the instructions of the ELISA kit to determine the levels of IgG and IgM in the serum.

[0060] 3. Statistical methods Graphpad Prism 9.0 software was used for data processing, and the measured data were expressed as mean ± standard deviation. The comparison among multiple groups was performed by one-way analysis of variance, and the comparison between groups was performed by SNK-q. The difference was considered statistically significant when P < 0.05.

[0061] 4. Experimental Results 4.1 Urinary D-xylose excretion and amylase (AMS) content Compared with the blank control group, the urinary D-xylose excretion and serum AMS content of rats in the model control group were decreased.

[0062] Compared with the model control group, the urinary D-xylose excretion and serum AMS content of rats in each group of the embodiment were significantly increased. Compared with the comparative example 1-5 groups, the groups of the embodiment had significant differences in increasing the D-xylose excretion and serum AMS content. Figure 1 、 Figure 2 .

[0063] 4.2 Organ Index Compared with the blank control group, the spleen index and thymus index of rats in the model control group were significantly decreased.

[0064] Compared with the model control group, the spleen and thymus indexes of rats in each group of the embodiment were significantly improved. Compared with the comparative example 1-5 groups, the spleen and thymus indexes of rats in each group of the embodiment were significantly improved. Figure 3 、 Figure 4 .

[0065] 4.3 Determination of serum immunoglobulin content Compared with the blank control group, the expression of IgM and IgG in the serum of rats in the model control group was significantly decreased.

[0066] Compared with the model control group, the expression of IgM and IgG in the serum of rats in each group of the embodiment was significantly increased. Compared with the comparative example groups 1 to 5, the expression of IgM and IgG in each group of the embodiment was significantly different. The results are shown in Table 1.

[0067] Note: Different lowercase letters in the same column indicate significant differences among different groups (P < 0.05).

[0068] After administering the mare's milk powder nutritional composition of the present invention to rats with spleen deficiency model, the rats' urinary D-xylose excretion and serum AMS content were significantly increased, the spleen and thymus indexes were significantly improved, and the expression of IgM and IgG in serum was significantly increased, indicating that the mare's milk powder nutritional composition of the present invention can improve the gastrointestinal absorption function of rats with spleen deficiency and enhance the immune function.

[0069] After the components of the mare's milk powder compositions in groups 1 to 5 of the comparative examples were reduced, the intervention effect on the spleen deficiency model rats was significantly weakened. The raw materials of the mare's milk powder composition of the present invention synergized with each other, significantly improved gastrointestinal function, improved spleen deficiency symptoms, and enhanced immunity.

[0070] The above embodiments do not limit the present invention in any form. For those skilled in the art, any modifications, replacements, etc. made within the scope of the technical solution of the present invention based on the technical essence of the present invention still fall within the scope of protection of the technical solution of the present invention.
