Abstract
This study aims to determine the increase of the growth of Deutch Democratic Yokohama (DDY) strain mice through a selection program from generation 0 (G0, n = 323 ), generation 1 (G1, n = 367) to generation 2 (G2, n = 386). The variables used for the selected program were weaning weight (WW) and adult weight (AW). For WW, the selection was made on the best 50% WW, and for the AW, the selection was carried out by choosing the best eight males and the best 32 females, using the value of genetic parameters and breeding values. Based on the study, WW increased from G0 to G1 and G1 to G2 of 12,63% and 12,05%, respectively. The increase in AW from G0 to G1 and G1 to G2 was 7,85 % and 17,78%, respectively. The conclusion was that it was possible to increase weaning weight and adult weight by selecting the program.
本研究旨在通过从第0代(G0, n = 323)、第1代(G1, n = 367)到第2代(G2, n = 386)的选择程序来确定德意志民主横滨(dy)系小鼠的生长增加情况。所选程序的变量为断奶体重(WW)和成虫体重(AW)。对WW进行50%的最佳选择，对AW进行遗传参数值和育种值的选择，选择8个最佳雄性和32个最佳雌性。研究表明，WW从G0到G1和G1到G2分别增加了12.63%和12.05%。从G0到G1和G1到G2的AW分别增加7.85%和17.78%。结果表明，选择该方案可提高断奶体重和成虫体重。
