And you're not understanding the machine itself takes by far most of that carbon which is released at a later point when it is slaughtered, not sequestered. It is released and wasted, most of it removed from the local cycle unless you Aussies are to the point of spreading human feces and butchers waste back on to fields.

No animal is a carbon sink. Some plants are, not grasses, but some plants can be. Some fungi might be. Animals are not.
