I have a finicky eating heifer. I need some ideas on how to increase her consumption. She weighs about 870#. She used to be my best eating heifer and now she's my worst. She gets fed 15#/day and out of that she eats 12#, when she really needs to be eating at least 18#. She doesn't seem sick either. I've tried mixing several different things in her feed with little success, she's on Sure Champ and I gave her a 3-day oral treatment of Vita-Charge, and have tried top dressing molasses on feed also. I'm open to any suggestions and thoughts. Thank you in advance!
