Correlated genetic trends for production and welfare traits in a mouse population divergently selected for birth weight environmental variability.
The objective of this work was to study the changes that, selecting for environmental variability of birth weight (BW), could bring to other interesting traits in livestock such as: survivability at weaning (SW), litter size (LS) and weaning weight (WW), their variability assessed from standard deviations of LS, standard deviation of WW (SDWW) and also the total litter weight at birth (TLBW) an...
متن کاملGenetic parameters and trends for lamb survival and birth weight in a Merino flock divergently selected for multiple rearing ability.
Data of 5,390 Merino lambs born from 1986 to 2007 (approximately 6.9 generations) were used to derive genetic parameters and trends for age-specific and overall lamb survival on the underlying scale, as well as for lamb birth weight, using Gibbs sampling. The majority of lambs were descended from lines that were divergently selected for the ability of ewes to rear multiples. The line selected i...
