[0082] (8) spray drying the concentrated solution in step (7) at an inlet temperature of 195° C. and an outlet temperature of 100° C. for 1 hour to obtain a milk thistle extract;

[0083] (9) Collecting milk thistle extract products and detecting the products, the content of silymarin in milk thistle can reach 85%. The silymarin extracted by this method has a high content and few impurities, which can reduce the impact of impurities.

[0084] Specifically, silymarin can also be obtained from silymarin capsules.

[0085] In one embodiment, in step S6, silymarin is first mixed with water and then added to the meat paste. Mixing silymarin with water can facilitate the silymarin to be more evenly mixed with the meat paste.

[0086] In one embodiment, in step S8, the content of silymarin in the meat paste is 250-500 mg / kg.

[0087] Specifically, each 1kg of the final product contains 250-500mg of silymarin; when adding silymarin, the amount of silymarin extract is obtained according to the total weight of fresh chicken, chicken liver and pork; and 300mg-600mg of silymarin extract is added to the total weight of 1kg of fresh chicken, chicken liver and pork. The addition of 300mg-600mg of silymarin extract can ensure that the final product contains 250-500mg of silymarin, which meets the product requirements.

[0088] Table 1 below shows the effects of silymarin content in nutritional products on the physical indicators of pet cats.

[0089] Table 1

[0090] Silymarin content (mg / kg)Pet physical indicatorsPet physical indicators Colostrum production (ml) Normal milk production (ml) Average daily food intake (g) Kitten weaning weight (g) Average daily weight gain of kittens (g) 0 74-105 396-584 120-190 396-816 9-15 250 94-126 467-603 130-210 453-942 12-17 300 103-118 508-635 130-220 506-981 13-18 350 101-127 506-659 130-210 510-954 13-17 400 111-119 536-641 140-210 528-969 13-18 500 96-125 483-655 130-210 461-933 12-17

[0091] The data in Table 1 were obtained by randomly dividing 120 multiparous female cats with the same recent conditions into 6 groups for control experiments. The feeding time of silymarin is from the 50th day of gestation of the female cat to the weaning of the kittens (weaning in the 5th week after birth). The values ​​obtained are all in the range of the lowest value to the highest value; the milk production will vary according to the number of kittens breastfed. The colostrum production and normal milk production in Table 1 are all based on the statistics of the female cat with 4 kittens.

[0092] According to Table 1, the milk production of mother cats increased after taking silymarin, and the daily food intake also increased. In addition, the weaning weight and average daily weight gain of kittens increased, indicating that the quality of the mother cat's milk is high.

[0093] Specifically, Table 1 also provides a group of control experiments, that is, 20 multiparous female cats with the same conditions as the above 120 are added as a group of experiments, and only silymarin is not added to the nutritional composition fed to the female cats. The experimental results are that the colostrum production is 90-112ml; the normal milk production is 459-601ml; the average daily food intake is 130-190g; the weaning weight of the kittens is 433-912g; the average daily weight gain of the kittens is 11-16g; according to the reorganization experiment, it can be known that the addition of fenugreek, tongcao and yimucao has the effect of promoting lactation; and the addition of silymarin can further improve the ability to produce milk.

[0094] Specifically, the various biochemical indicators of cats in Table 1 were tested, such as alanine aminotransferase (ALT), the normal range of which is 20-107 U / L. Aspartate aminotransferase (AST), the normal range is 6-44 U / L. Blood urea nitrogen (BUN), the normal range is 17-30 mg / dL. Creatinine (CREA), the normal range is 0.6-2.0 mg / dL.

[0095] After taking the nutritional composition containing 250mg / kg-500mg / kg of silymarin, the above-mentioned alanine aminotransferase, aspartate aminotransferase, and blood urea nitrogen content were all within the normal range, indicating that silymarin at this content is beneficial to the liver function of pet cats. In addition, the daily food intake of mother cats increased, and the weaning weight of kittens increased, indicating that silymarin can improve the metabolic performance of pets and improve their physical condition.

[0096] In one embodiment, Table 2 is prepared by taking a pet cat intake group with a silymarin content of 250 ml and a pet cat with a silymarin content of 0 ml as a control group, and taking the average value of the lactation amount / ml of the mother cat at the same time within 24 hours after delivery, within the 7th day, within the 14th day and within the 21st day, instead of the milk production in one day.

[0097] Table 2

[0103] Serial number Milk production (ml) Average daily food intake (g) 1 396-584 120-190 2 467-603 130-210 3 453-611 140-220

[0104] Serial number 1 does not use this product, serial number 2 uses this product but does not add Patchouli, Scutellaria barbata, dried tangerine peel and licorice, and serial number 3 uses this product and adds Patchouli, Scutellaria barbata, dried tangerine peel and licorice.

[0105] By adding the traditional Chinese medicines of Patchouli, Scutellaria barbata, Tangerine peel and Licorice, the food intake of pet cats can be increased, and the body performance and metabolic performance of pet cats can be improved.

[0106] The main effects of the combination of licorice and tangerine peel are to relieve the symptoms of indigestion, nausea and vomiting, and can effectively treat the weak spleen and stomach of pet cats.

[0107] The main effects of Patchouli include relieving heat, eliminating dampness and stopping vomiting.

[0108] It can be used to treat symptoms such as heatstroke, nausea and vomiting caused by spleen and stomach disharmony.

[0109] When used with dried tangerine peel, it can eliminate dampness and relieve heat, harmonize the stomach and stop vomiting, and help restore appetite; when used with pinellia, it can dry out dampness and resolve phlegm, reduce adverse effects and stop vomiting; when used with talc, it can clear away heat and dampness, and stop diarrhea; when used with curcuma, it also has corresponding medicinal effects.

[0110] Scutellaria barbata is used to clear away heat and detoxify, and is anti-inflammatory and diuretic. In traditional Chinese medicine, it is used as an auxiliary treatment for diseases such as hepatitis and tumors.

[0111] Tangerine peel mainly plays the role of regulating qi and strengthening the spleen, drying dampness and resolving phlegm. It can be used to treat symptoms such as spleen and stomach disharmony, cough with damp phlegm, etc. Tangerine peel is compatible with drugs such as Patchouli and Atractylodes macrocephala to enhance the effects of strengthening the spleen and drying dampness, promoting qi and strengthening the spleen.

[0112] Licorice has the effects of relieving cough, moistening the lungs and relieving pain, and is usually used to treat symptoms such as colds, coughs, and gastric ulcers.

[0113] Table 4 shows the effects on the physical indicators of pet cats when the silymarin content in the nutritional product is 250 mg / kg, the weight ratio of fenugreek, tongcao and leonurus is 3:1:4, 5:3:8 or 8:6:12. The preferred ratio is 5:3:8, and the weight ratio of chicken, chicken liver and pork is 2:1:2, 5:2:3 or 8:4:6.

[0114] Table 4

[0115] (Vaccaria, Tongcao, Leonurus japonicus) + (chicken, chicken liver and pork) Colostrum production (ml) Normal milk production (ml) Average daily food intake (g) Kitten weaning weight (g) Average daily weight gain of kittens (g) (3:1:4)+(2:1:2) 90-130 456-577 130-210 448-903 11-16 (5:3:8)+(5:2:3) 94-126 467-603 130-210 453-942 12-17 (8:6:12)+(8:4:6 97-120 431-617 130-210 443-958 12-17

[0116] It can be seen from Table 4 that the effects of the mixture of (Vaccinium segetalis, Tongcao, Yimucao) + (chicken, chicken liver and pork) on the physical indicators of pet cats are not much different; when the ratio of (Vaccinium segetalis, Tongcao, Yimucao) + (chicken, chicken liver and pork) is (5:3:8) + (5:2:3), the physical indicators of pet cats are relatively good, that is, the comprehensive indicators of colostrum production, normal milk production, kitten weaning weight and average daily weight gain of kittens are better.
