climate change

[aimeeh kirkwood dexters]

hello all
hope everyone is keeping ok
this is a question for everyone but especially the ones that deal with the meat side
as part of my animal management course we have to do a project. we get given a theme but have to come up with a title. I have come up with
'Has climate change affected the carcass weight of cattle on a local regional and global level'
before I submit my form, I was just wondering if people do think climate change has affected carcass weights or whether it is related to something else.
many thanks
aimee

Sorry, I think the short answer is no. I discussed different phenotypes within one population in a poster that is online on my academia page, Google Estimated withers heights and the range of height within a population: modern Dexter catalogue as an analogue for Romano-British cattle.
In particular this reference:
