[0055] Test Example 1

[0056] 1. Determine the nutritional components of the meat rabbit feed in Example 1 and Control Example 1, and the results are shown in Table 1.

[0057] Table 1 Nutritional components of different feeds

[0058] Nutritional components Control group 1 Example 1 Crude protein (%) 17.28 16.81 Crude fat (%) 2.26 2.29 Crude fiber (%) 16.54 17.05 Crude ash (%) 6.76 6.41 Neutral detergent fiber (%) 24.04 26.49 Acid detergent fiber (%) 19.15 19.47 Lysine (%) 0.95 0.92 Methionine + cystine (%) 0.54 0.55 Calcium (%) 1.13 1.01 Phosphorus (%) 0.45 0.44 Digestible energy / (MJ / kg) 9.45 9.72

[0059] It can be seen from Table 1 that the nutritional components of the meat rabbit feed in Example 1 are comparable to those in Control Example 1.

[0060] 2. Conduct a 54-day feeding experiment on meat rabbits using the meat rabbit feed in Example 1 and the meat rabbit feed in Control Example 1, and determine the effects of different feeds on meat rabbits.

[0061] The 60 meat rabbits used in the experiment were 35-day-old Yila meat rabbits, purchased from Gansu Hezheng Lüyuan Comprehensive Breeding Farmers' Professional Cooperative.

[0062] Experimental grouping: Randomly divide 12 meat rabbits into 2 groups, with 6 rabbits in each group, and set 5 replicates in each group. One group is fed the meat rabbit feed in Example 1, denoted as the PHP group, and the other group is fed the meat rabbit feed in Control Example 1, denoted as the CON group.

[0063] Test method: Before the test, each group was given a 6-day preliminary test period to allow the meat rabbits to adapt to various conditions and environments of the test as soon as possible. After the preliminary test period ended, a 54-day feeding test was conducted. Specifically, the two groups of test meat rabbits were caged and raised in a rabbit house with constant temperature and humidity, good ventilation, and regular cleaning and disinfection, and were fed meat rabbit feed at 08:00 and 18:00 every day, and free drinking water was provided.

[0064] 2.1 Effects of different treatment groups on the growth performance of meat rabbits

[0065] Before feeding the meat rabbit feed at 08:00 on the 0th, 28th, and 54th days of the feeding test, the meat rabbits were weighed, and the feeding amount of the meat rabbit feed for each group of rabbits was recorded every day. The remaining meat rabbit feed was collected and weighed before 08:00 the next day. After the feeding test ended, the average daily gain of each group of meat rabbits was calculated using the weight difference of the meat rabbits on the 0th, 28th, and 54th days, and the average daily feed intake of the two groups of meat rabbits was calculated using the difference between the daily feeding amount of the meat rabbit feed and the remaining amount of the meat rabbit feed the next day. The growth performance indexes of the meat rabbits in different treatment groups were measured, and the data were analyzed for differences. The results are shown in Table 2. Different lowercase letters in the table indicate significant differences (P < 0.05), and the same letters indicate no significant differences (P > 0.05).

[0066] Table 2 Growth performance of meat rabbits in different treatment groups

[0067] Index CON group PHP group P value Initial body weight (g) 1535.97±154.28 1568.80±163.90 0.428 Final body weight (g) 2706.25±290.88 2863.50±213.55 0.051 Average daily gain (g / d) 19.30±4.12 20.99±3.64 0.162 Average daily feed intake (g / d) 122.20±29.99 124.79±32.29 0.614 Feed conversion ratio 6.84±2.69 6.22±1.79 0.381

[0068] According to Table 2, although there was no significant difference in the growth performance between the CON group and the PHP group of meat rabbits, the overall growth performance of the PHP group was higher than that of the CON group.

[0069] 2.2 Effects of different treatment groups on the slaughter performance of meat rabbits

[0070] After the feeding test ended, the meat rabbits were slaughtered. The meat rabbits were stunned by hitting the back of the head, bled, skinned, the front limbs were removed at the wrist joint and the hind limbs were removed at the tarsal joint. After removing the intestines and contents and urogenital organs, the head was removed at the first cervical vertebra, the trachea and esophagus were removed, and the liver (gallbladder removed), kidneys and perirenal fat were retained and weighed, which was the semi-eviscerated weight; after removing the heart, liver, kidneys and perirenal fat and weighing, it was the eviscerated weight. Five meat rabbits were randomly selected from each group for boning, the net meat weight was weighed, and the net meat rate was calculated. The calculation formulas for the semi-eviscerated rate, eviscerated rate and net meat rate are as follows:

[0071] Semi-eviscerated rate (%) = semi-eviscerated weight / live weight before slaughter × 100%;

[0072] Eviscerated rate (%) = eviscerated weight / live weight before slaughter × 100%;

[0073] Net meat rate (%) = Net meat weight / Live weight before slaughter × 100%.

[0074] The slaughter performance indexes of two groups of meat rabbits were measured, and the data were analyzed for differences. The results are shown in Table 3. Different lowercase letters in the table indicate significant differences (P < 0.05), and the same letters indicate no significant differences (P > 0.05).

[0075] Table 3 Slaughter performance of meat rabbits in different treatment groups

[0076] Index CON group PHP group P value Semi-eviscerated weight (g) <![CDATA[1630.02±87.32 b > <![CDATA[1738.65±65.03 a > 0.005 Eviscerated weight (g) <![CDATA[1509.9±82.92 b > <![CDATA[1606.4±66.93 a > 0.010 Meat weight (g) 1101.6±64.39 1045.6±182.53 0.546 Semi-eviscerated rate (%) 55.23±2.83 54.74±1.66 0.643 Eviscerated rate (%) 51.17±2.87 50.57±1.71 0.580 Meat yield rate (%) 38.08±2.69 33.21±5.24 0.101

[0077] According to Table 3, compared with the CON group, the PHP group significantly increased the semi-eviscerated weight and eviscerated weight of meat rabbits, enhancing the slaughter performance of meat rabbits, indicating that the meat rabbit feed in the examples can significantly improve the slaughter performance of meat rabbits.

[0078] 2.3 Effects of different treatment groups on the meat quality of meat rabbits

[0079] After the feeding experiment, the meat rabbits were slaughtered, and the left hind leg meat of the meat rabbits was taken. The pH was measured using a portable pH meter testo-205 at 45 minutes and 24 hours after slaughter; the meat color was measured using a color difference meter CR-410 at 45 minutes and 24 hours after slaughter, measuring the red-green degree (a), yellow-blue degree (b), and brightness (L) in the middle section of the meat sample. The cooking loss was measured. The specific method was to cut 5 g of the meat sample into cubes, boil it in boiling water for 30 minutes, hang it for 30 minutes, and then weigh it to calculate the cooking loss rate. The drip loss was measured. The specific method was to cut 5 g of the meat sample into cubes, hang it at 4°C for 24 hours, absorb the surface moisture, and then weigh it to calculate the drip loss rate. The tenderness was measured. The specific method was to heat the meat sample to a central temperature of 75°C after the drip loss, cool it, and then measure the shear force value using a muscle tenderness meter RH-N50. The calculation formulas for cooking loss and drip loss are as follows:

[0080] Cooking loss (%) = (Sample weight - Sample weight after heating) / Sample weight × 100%;

[0081] Drip loss (%) = (Sample weight - Sample weight after hanging) / Sample weight × 100%.

[0082] The meat quality indexes of the two groups of rabbit meat were calculated according to the formulas, and the data were analyzed for differences. The results are shown in Table 4. Different lowercase letters in the table indicate significant differences (P < 0.05), and the same letters indicate no significant differences (P > 0.05).

[0083] Table 4 Effects of different treatment groups on the meat quality of meat rabbits

[0084]

[0085]

[0086] As can be seen from Table 4, compared with the CON group, the PHP group can significantly increase the brightness (L) at 45 minutes, the yellow-blue degree (b) at 45 minutes, and the brightness (L) at 24 hours in rabbit meat, indicating that the rabbit feed in Example 1 can significantly improve the quality of rabbit meat.

[0087] 2.4 Effects of different treatment groups on the digestive organs of rabbits

[0088] After the feeding trial, the rabbits were slaughtered, and the duodenum, jejunum, ileum, cecum, colon, rectum, vermiform appendix, and stomach organs were taken out respectively, then weighed, and the lengths of the duodenum, jejunum, ileum, cecum, colon, rectum, and vermiform appendix were measured. The weight index and length index of the digestive organs were calculated. The calculation formulas for the weight index and length index of the organs are as follows:

[0089] Digestive organ weight index (%) = digestive organ weight / live weight before slaughter × 100%;

[0090] Digestive organ length index (%) = digestive organ length / total length of digestive organs × 100%.

[0091] The weight indexes of the digestive organs of the two groups of rabbits were measured, and the data were analyzed for differences. The results are shown in Table 5. Different lowercase letters in the table indicate significant differences (P < 0.05), and the same letters indicate no significant differences (P > 0.05).

[0092] Table 5 Weight indexes of digestive organs of rabbits with different treatments

[0093]

[0094]

[0095] As can be seen from Table 5, there is no significant difference in the weight indexes of the digestive organs between the two groups of rabbits.

[0096] The length indexes of the digestive organs of the two groups of rabbits were measured, and the data were analyzed for differences. The results are shown in Table 6. Different lowercase letters in the table indicate significant differences (P < 0.05), and the same letters indicate no significant differences (P > 0.05).

[0097] Table 6 Length indexes of digestive organs of rabbits with different treatments

[0098] Index CON group PHP group P value Duodenum 10.47±3.76 11.39±3.3 0.569 Jejunum 48.73±4.18 50.22±3.31 0.388 Ileum 5.96±0.83 5.34±1.45 0.250 Cecum 7.94±0.44 8.13±0.8 0.507 Colon 7.95±0.47 8±0.97 0.893 Rectum <![CDATA[13.98±2.39 b > <![CDATA[16.09±1.28 a > 0.028 Vermiform appendix 10.47±3.76 11.39±3.3 0.569

[0099] As can be seen from Table 6, compared with the CON group, the PHP group can significantly increase the length of the rectum of the digestive organs of rabbits, indicating that the rabbit feed in Example 1 can significantly increase the length of the rectum of the digestive organs of rabbits.

[0100] 2.5 Effects of different treatment groups on the gastrointestinal tract of rabbits

[0101] After the feeding trial, the meat rabbits were slaughtered. A portable pH meter testo-205 was used to quickly measure the pH values of the contents of each digestive organ. At the same time, cecal contents were collected as test samples, frozen quickly in liquid nitrogen and then transferred to -80 °C for storage. Shanghai Majorbio Bio-Pharm Technology Co., Ltd. completed the sequencing analysis of the gastrointestinal microbiota composition of the test samples. The measured results of the pH values of the digestive organs of meat rabbits under different treatments are shown in Table 7, and the results of the gastrointestinal microbiota composition are as Figure 1 and Figure 2 shown. Figure 1 indicates the differences in the cecal microbial phylum-level composition of meat rabbits under different treatments, Figure 2 and indicates the differences in the cecal microbial genus-level composition of meat rabbits under different treatments.

[0102] Table 7 pH values of the digestive organs of meat rabbits under different treatments

[0103] Index CON group PHP group P value Duodenum 6.78±0.38 6.53±0.18 0.122 Jejunum 6.94±0.67 6.57±0.18 0.115 Ileum <![CDATA[7.98±0.38 a > <![CDATA[7.19±0.39 b > 0.001 Cecum 6.58±0.18 6.6±0.21 0.831 Colon 6.95±0.47 6.63±0.18 0.052 Rectum <![CDATA[6.94±0.3 a > <![CDATA[6.66±0.28 b > 0.043 Vermiform appendix 6.76±0.41 6.67±0.18 0.553

[0104] As can be seen from Table 7, compared with the CON group, the PHP group significantly reduced the pH values of the ileum and rectal organs, and had no effect on the pH values of other digestive organs, indicating that the meat rabbit feed in Example 1 could significantly reduce the pH values of the ileum and rectal organs.

[0105] According to Figure 1 and Figure 2 it can be known that at the cecal microbial phylum level, the Pseudomonadota in the cecum of meat rabbits in the CON group was significantly higher than that in the PHP group; at the cecal microbial genus level, the relative abundances of Odoribacter, Ruminococcaceae_UCG_009, norank_f__Desulfovibrionaceae, Candidatus_Soleaferrea, and norank_p__Bacillota in the cecum of meat rabbits in the CON group were significantly higher than those in the PHP group, and the relative abundance of Frisingicoccus in the cecum was significantly lower than that in the PHP group. This indicates that the meat rabbit feed in Example 1 can change the microbial composition of the cecum and reduce the relative abundances of harmful microorganisms.

[0106] As can be seen from the above embodiments, the present invention provides a meat rabbit feed, and the meat rabbit feed comprises the following components in parts by mass: 3.5-4.5 parts of alfalfa, 0.5-1.5 parts of timothy grass, 1.5-2.5 parts of corn, 1-2 parts of soybean meal, 0.2-0.6 parts of wheat bran, 0.1-0.3 parts of beet molasses, and 0.4-0.8 parts of premix. Feeding meat rabbits with the meat rabbit feed of the present invention can improve the growth performance and slaughter performance of meat rabbits, and also improve the quality of rabbit meat and regulate the balance of the intestinal flora of meat rabbits.

[0107] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
