Thanks to point that out, my English isn’t perfect and a quick search show me that a caw is a female :-)

I wasn't explicit enough here neither: "we slaughter [...]" -> "Humans slaughter [...]". I'm not farmer, just some random guy.

For the profitability part : "The value of cull cows at slaughter represents a source of income for dairy farms."[1]

However the profitability incentives varies depending on the breed and lead to ...strange... practices: the male newborn are hardly profitable if from a diary-super-optimized breed and some farms culled them at birth [2]. It's now forbidden in UK but still a practice in Switzerland (yummy Toblerone).
