The Colostrum Counsel – Dealing with Diarrhea: A 4-step Approach
November 2025
Neonatal Calf diarrhea (NCD), also known as scours, remains one of the most significant health challenges in pre-weaned calves contributing to high treatment rate, risk of death, and decreased future productivity on both dairy and beef operations. Even mild cases can have long-term impacts on growth and overall performance. While diarrhea is often seen as an unavoidable part of calf rearing, most outbreaks can be linked to management factors that can be improved with the right attention to detail.
Here are 4 steps you can take when dealing with diarrhea to improve calf outcomes:
1. Review colostrum management. Ensure the colostrum being fed has at least 50g of immunoglobulins (IgG) per liter and limit bacterial contamination through clean handling practices such as feeding as soon as possible and IgG safe pasteurization (140 °F or 60 °C for 60 min). Calves should receive colostrum within the first 6 hours after birth.
