My 24 mo. holstein heifer is due to freshen on Aug. 16th give or take what God determines. I have her on alfalfa/grass hay combo and she gets grain in the evening (about 4 cups). I have iodided loose salt mix out for free feed and there is usually baking soda and goat minerals that she gets into. What should I be doing for this last month other than praying that the lil' one is in the right position? This is my first experience at all this. I have a great vet and two other people that will help if things head south. Thanks.
