I Have a 9 month old heifer that is 50% Holstein, 25% Charolais and 25% Angus. Her weight is about 650 lbs. (wieght was estimated by using body measurments). Since weaning, I have been feeding her 8 lbs. of a steam rolled corn, pellet, oats and molasses mix type food (16% protien) and 25% to 50% of an average quality square bale hay a day. Outside conditions deturmined the amount of feed fed. I have just switched her to a better quailty hay same amount as before and, 8lbs. of a 20% protien dairy pellet per day. Should I continue on this type of a feeding program or should I change something? What has worked for you? Also I think she has already started to show breding behavior such as mounting other cows, making more noise than is normal for her, and acting somewhat restless. Is this normal for her age? Is she already starting to cycle? I raised her since she was one week old so I know this is her true age. Thank you.
