Quite true. Here's a WW2 era poem for proof.
"The lament of the artificially inseminated cow"
I've just given birth to a calf, Sir
And with motherly pride I am full
But please do not laugh and pray do not chaff
When I tell you I've not had a bull
The farmyard's the dreariest place, Sir
The meadow no longer so gay
Since the one spot of fun in the year's dismal run
Has by science been taken away
No bull has embraced me with passion
I've not had the ghost of a binge
I've never been loved but ruthlessly shoved
With a dirty great brass bound syringe
You may say that's all very well, Sir
There are some things a cow cannot say
But those Land Army tarts who have done with our parts
Still get it the old fashioned way
I saw it written on a sheet of paper about 60 years ago. By Michael Barsley, I think.
