I just got a new bull 4 year old limousin ( double black,double polled)not sure about birth weight, I've been using a angus (he's 7) small birth and all the calves have been healthy, so far I've only had to pull 1 calf with him, they both lived.I have 3 questions the first I want to put on more roundness and faster growth. Will this new bull help with this? Second the angus "Slow Motion" I've noticed one of his testicles is becoming smaller, is this because of his age? third question is I just 2 more calves and one is a little bull he's 4 months old. Can I still band him?
