Non-saleable waste milk can be an economical feed for calves, as a growing number of dairies and calf ranches have learned. However, a case study offered by Dale Moore, Washington State University director of veterinary extension and colleagues, indicates that — due to wide product variability — quality control is needed if these feeding programs are to be successful. The researchers recommend veterinarians offer the following assistance in such programs:
- Develop ways to measure milk quality.
- Provide feedback to dairies supplying waste milk.
- Develop ways to ensure consistent, quality nutrients are provided to young calves.
- Develop protocols so that employees can assess and remediate, if necessary, total solids fed to calves in liquid-feeding programs.
