How many ticks/work does milking slaughtering take?

[pllovervoltage]

Does anybody know how ticks/work milking slaughtering take?
For plants, I found that sowing and harvesting take 170 and 250 respectively in the Plants_Bases.xml file within the ThingDefs_Plants folder. But the ThingDefs_Races folder has all the specific animals and how much milk/eggs they yield at what intervals but no line or separate base.xml for milking animals. I've basically looked over every field and perhaps I looked over it but I can't seem to find it. Does anybody know where I can find the lines in the xml file for milking and slaughtering?
