(4) selecting 120 pure black hirsute in the F2 generation, large body type, high growth speed, strong stress resistance and strong parent fertility female rabbits and 30 male rabbits for selfing to obtain an F3 generation;
(5) And (5) repeating the step (4) until the body and the appearance are basically consistent, the hereditary performance is stable, and the high-quality black meat rabbits are cultivated. In the breeding after the F3 generation, the selection criteria are as follows: all the offspring rabbits must be pure black, the litter size of the parent generation must be more than 9 and 9, the survival rate of weaning litter must be more than or equal to 7, the weight of 35 days old must be more than or equal to 630g, the weight of 70 days old must be more than 2200g, and the weight of adult rabbits is more than 4100 g.
The environment temperature for feeding all rabbits in the above examples 1-2 and comparative examples was between 10 ℃ and 22 ℃, and all the female rabbits involved in the breeding were bred within 3 days after birth for the next birth, the young rabbits were fed at 18 days old, the young rabbits were weaned at 22 days old and kept from the milk and their litter, the drinking water of the young rabbits weaned at 22 days old was completely replaced with artificial milk, which was blended with hot water and whole milk powder, and the young rabbits were fed with artificial milk until 35 days old, and the commercial meat-substituted rabbits were obtained in examples 1-2, respectively, and the black hair meat rabbits were obtained in comparative examples.
Examples of the experiments
The average weight of the black meat rabbits obtained in the comparative example at 35-day age is 638 +/-70.2 g, the weight of the rabbits at 70-day age is 1870 +/-261 g, and the weight ratio of the feed at 35-70-day age is (3.31 +/-0.16): 1.
The weight and feed consumption of the new meat rabbit line obtained in example 1 were measured on different weeks, and the feed-to-weight ratio was calculated, averaged, and recorded in table 1.
TABLE 1 table of the material consumption for commercial meat-substituted rabbits
| Time of week | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| body weight (g) | 674.60 | 1037.33 | 1320.13 | 1610.22 | 1916.47 | 2211.51 | 2430.94 | 2730.29 | 2946.30 |
| feed consumption (g) | - | 491.84 | 1097.76 | 1890.73 | 2868.23 | 4019.75 | 5175.39 | 6364.76 | 7531.75 |
| material to weight ratio | - | 1.37 | 1.70 | 2.02 | 2.32 | 2.63 | 2.95 | 3.10 | 3.32 |
As can be seen from the data in Table 1, the weight of the new meat rabbit strain obtained in the example 1 is obviously superior to that of the meat rabbits obtained in the comparative example at the ages of 35 days (5 weeks) and 70 days (10 weeks), and the material-weight ratio is obviously smaller than that of the meat rabbits obtained in the comparative example, so that the new meat rabbit strain obtained in the example 1 has strong production performance, the feed reward of the new strain is high, the breeding benefit is good, and the new meat rabbit strain is worthy of popularization and feeding.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
