My brother in law has a heifer with a newborn calf and 2 bulls. He has never given them anything but hay and their pasture. He's asked me to look into what all they need. The necessities basically. I'm hoping someone here with experience in raising cattle can help me, because all the info I've found so far is a bit overwhelming. What vaccines do they NEED? Minerals? Wormers? He is milking the cow and is concerned about the milk being "bad" because the cow has had zero vaccines since spring 2016 when he purchased her. I hope this makes sense lol I haze zero experience with cattle. Thanks!
