What is the cheapest animal you have

Cheapest depends on the species. If you want a dairy animal, usually a local cow or a buffalo calf is cheaper than a milking animal. For milk business, look at Sahiwal, Gir, HF cross, Jersey cross in cows, and Murrah, Nili Ravi, Jaffarabadi in buffaloes. Tell me which animal you want, and I will guide you to the cheapest practical option for milk.
