If you want a pointer, you can start here : https://en.wikipedia.org/wiki/Price_elasticity_of_demand https://en.wikipedia.org/wiki/Price_elasticity_of_demand The idea is that if someone able to afford a cow 1000$ does not buy it, then it will be sold to someone willing to to buy it 999$ and who could not afford it before. To have a real impact on the market and the incentives to raise cattle, you'd need a real lot of people to become vegan. The link you shared is very weak on evidence (there are none) and a decrease in sales can be caused by a lot of factors.
