Embodiment 1
[0034] The present embodiment provides the breeding method of described a kind of white meat rabbit three-line matching line, comprises the following steps:
[0035] (1) Select the male rabbits of the ancestor breeding rabbit GD24 of the Ipru meat rabbit matching line with obvious breed characteristics to mate with the GD14 female rabbits of the Ipru meat rabbit matching line to produce the parent generation PS19 male and female rabbits;
[0036](2) BC16 male and female rabbits produced by backcrossing the PS19 male rabbit described in step (1) with the GD14 female rabbit described in step (1); The BC15 male and female rabbits were produced by handing over; the BC15 male and female rabbits were cross-propagated and multiplied to form a basic group, and 4 generations of locked-up subculture were selected, and the offspring with good adaptability, excellent production performance and reproductive performance were selected as special The mother line I system, specifically as fig...
Embodiment 2
[0043] The difference between this example and Example 1 is that the locked-up subculture selection in steps (2), (3) and (5) is 3 generations of locked-up subculture selection, and other operations are the same as in Example 1.
experiment example
[0052] The average body weight of the black meat rabbits obtained in the comparative example was 638±70.2g at the age of 35 days, 1870±261g at the age of 70 days, and the ratio of feed to weight at the age of 35-70 days was (3.31±0.16):1.
[0053] The body weight and feed consumption of the new meat rabbit strain obtained in Example 1 were measured in different weeks, and the feed-to-weight ratio was calculated, and the average value was taken, and recorded in Table 1.
[0054] Table 1 - Growth Consumption Table of Meat Rabbit New Strains (unit g)
[0055] Week 4 5 6 7 8 9 10 11 12 weight 681.95 1003.03 1277.77 1580.76 1905.44 2216.38 2427.50 2732.17 2937.35 feed consumption - 488.80 1092.07 1918.79 2893.06 4034.79 5161.79 6349.32 7448.70 material to weight ratio - 1.53 1.85 2.14 2.37 2.63 2.96 3.09 3.30
[0056] As can be seen from the data in Table 1, the body weight of the new meat rabbit strain obtained in Ex...
