Liquid feed and/or cubes are generally a stopgap when you have standing grass that is poor grazing. Both have a point of efficiency also that can be surpassed. Both are great at a certain usage because of convenience but if the rates get too high they get really expensive. At that point you have to bring in a feed source like hay, wcs, or ground feed, etc.
A big decider for me is if we are about to drop calves and conditions are bad we will feed wcs. There is a 4 month window there that is crucial to breedback and kick that calf off.
Even that has a breaking point where you are better off early weaning and feeding them separately.
As a comparison, wcs is running around $11 for #50, $220/1000 in a tote. A cheap cube is around $14 a sack, which I wouldn't feed, and a 40% cs cube is like $16 or $18. None of them will have the fat of the wcs which is what I want for a cow to milk a calf and re-beed.
