I am seriously considering buying a family cow. Hoping some of you could help me with things to look for, questions to ask. We have had goats for 7 years so I know a little from that perspective. I am hoping for a Jersey but would consider a holstein cross or almost anything healthy and gentle with milk. There are lots of dairy farms here in Maine to inquire at. Hoping to not have to buy at the auction... My friend did pick up a Jersey at auction last Fall. She got a Jersey 8yo at the end of lactation with mastitis in one quarter. She is due to calf in July. My friend paid $300 at auction. The cow is gentle and the milk is good...I actually milked a few times. She had her vet come out and thoroughly inspect her for an add'l $100. Keep in mind that prices are cheaper here than in the midwest. I am hoping to get a cow for 3-500$ or a cow/calf(bull) for $600. What diseases should they be tested for? How much info. do you think I could get on the cows production (milk)? How do you tell age of a cow?
