Implementation Selection to Increase Body Weight Fancy Mice
Abstract
Use laboratory animal for research purposes is often used especially in the fields of health research, food, agriculture, and livestock. The laboratory animal that is often used as research objects include rabbits, mice, guinea pigs, monkeys, and rats. Research in the field of livestock in animal breeding requires a long time to research and a large number of animals so mice can be used to apply it. The goal of research is determine effect of the selection program on parameters of mice body weight including weaning weight and adult weight. The research was held with Fancy mice keeping and selection implementation of weaning weight 21 days age (WW21) and 35 days age (AW35) which starts from 0 generation until 2nd generation. The data used in the selection of Fancy mice on 0 generation until 2nd generation each of 327 tails, 330 tails, and 263 tails. The result of the selection of Fancy mice to WW21 increased obtained WW21 G0 to G1 is 3.69 gram and WW21 G1 to G2 is 2.09 gram. Selection of Fancy mice to AW35 that result in AW35 G0 to G1 is 5.14 gram and AW35 G1 to G2 is 4.92 gram, which means selection is impacting increased WW21 and AW35 Fancy mice.
