Selection for ‘environmental fit’ from existing domesticated species
|Author(s) :||A.B. Lawrence & E. Wall|
The selection of farm animals through breeding for human benefit has a very long history. In more recent times the practice of animal breeding has become highly sophisticated and the speed of change in ‘production traits’ such as rate of growth and milk yield has correspondingly increased dramatically. This narrow focus on production traits led to a number of well-documented examples of ‘unfavourable’ correlated responses such as negative fertility and health issues in high-yielding dairy cattle, with concerns that animal breeding is inherently antagonistic to animal welfare.
