i have been hand raising a calf since the 17th june, when born it fell approx 1.5m. she seemed to be feeding well on her first night (gave her some colostrum), the next morning it was a struggle to get her to feed, we also noticed she had what we believed to be scours (yellow diarheoa with blood in it), we adventually got her to feed again around 2pm that day. the following day (day 3) she was happily walking around mooing for her feed. i believe i could have possibly over fed her as ilet her drink 1L of her formula. throughout the day she would not feed and her scours seemed to be increasing. i began giving her replacement electrolytes. throughout this entire period she was very strong and able to walk around, and struggle against you if she didn't want to drink. day 4 she was again walking around mooing for her feed. i fed ger approx 500ml of formula at 6.30am, my partner feed her approx 400ml of formula at 12.30pm and i fed her again at 7pm. her scours appeared to have cleared up and she was doing solid bowel movements. my partner came home from work and checked her at approximately 2am to find her dead (slightly cold but not stiff so it must have been quite recent when he found her). i am wondering what could have possibly caused this as she seemed so healthy a few hours earlier and was very willing to drink. i am looking at hand raising more calves in the future and would like to know if it was somethig i did wrong to avoid it next time.
