Mothers are important for good animal welfare

Mothers are important for good animal welfare

It is Mother’s Day this year on 31^st March so we will take this opportunity to consider how mothers play a key role in animal welfare. Only 3% of mammalian species involve fathers in rearing offspring, so for mammals mothers are really important for offspring development and welfare. Maternal care is also shown in birds, and some species of fish, reptiles, amphibians and even insects. Mothers play a vital role in the survival of their offspring through determining where the offspring will be born or the environment in which they will spend their early life. They also provide food, warmth, comfort and opportunities for learning to their offspring. However, mammalian and avian mothers (and maybe other species as well) do even more – through subtle changes in the uterine environment for mammals, or the composition of the egg in birds, mothers are able to ‘signal’ to their offspring before birth to prepare them for the sort of environment they will be living in. This can change how stress reactive an animal will be after birth. If the environment is very risky then this can improve the survival of young animals in the wild. However, for domesticated animals a stressed mother can lead to offspring that are more stress reactive and this may be bad for their welfare, leading to excessive fearfulness or anxiety after birth. Looking after pregnant and lactating mothers carefully does not only help to improve the welfare of the mother, but also that of their unborn offspring throughout their lives.

JMICAWE Director, Prof Cathy Dwyer, will be discussing these aspects of animal husbandry as an invited speaker at the British Society for Animal Science meeting in Edinburgh on 10^th April (https://bsas2019.expom.io/).
