> I don't really know what you mean by it being part of carbon cycle

Plants breath in co2 from the atmosphere and bind the carbon in their structure. Cows eat the plants and turn some percentage of the bound carbon into cow meat, the rest they poop or fart or breath out. Eventually all that carbon ends up back in the atmosphere where plants again can bind it. This is the carbon cycle. Thus the point is that cows existing do not increase the carbon in circulation. (As opposed to digging up coal or drilling for oil/gas which liberates carbon which used to be in circulation but become bound in fossils.)
