What protocol do you use when bringing new calves into your place. I just bought an old man's herd of open heifers for a deal I couldn't turn down. They are angus brangus cross heifers 14-16 monthes old. ready for a bull. This man is selling about 60 of his 160 cows for a lack of winter feed. they have had all vaccanations but do you go ahead and give them a round anyway. I planned on keeping them away from my other heifers for about 10 days. what do you do when introducing unknow cattle to your herd. by the way i bought the open heifers for $600 per head. they weigh between 700-900 lbs. If anyone is interested he has some charlois pairs and 3 n 1's for $1200 per pair. some of the calves are 250-400 lbs. I would buy them but they are the wrong color and I am over cowed for my pastures as it is.
