Why I wanted this mentorship
Project
Feeding calves milk replacers containing different protein sources, watching the performance before and after weaning.
• Background• Objective
Dairy Farms
• Clay View Dairy• Wolf Creek Dairy• Bombay Dairy
Calf feeding Systems
• Waste whole milk• Milk replacer

What they are testing
What are they trying to answer?
Will the weight gain and health of the calves change from partial replacement of milk protein with plant source proteins which are that less expensive?
Standard Protocol
• Start with a strong healthy calf.• A non-medicated all-milk protein milk
replacer (20% fat:20% protein) is fed at 1.25 lb a day mixed with water for 35 days and half that from day 36 to weaning at day 42.
• Medication is added to the milk replacer for 14 days after arrival to prevent health problems.
• A texturized 18% crude protein calf starter is offered free choice as well as fresh water.
What is calf starter?
The stomach of a calf
• The stomach of a calf consist of four parts.– Reticulum– Rumen– Omasum– Abomasum (true stomach)
Abomasum
Rumen
Data Collection
• Fecal scores are recorded daily and summarized weekly by treatment through 4 weeks of age.
• Health, treatment, and death loss records are recorded on an individual calf basis.
• Blood samples are taken from each calf upon arrival and analyzed for serum protein.
• Treatment days and cost are recorded for each treated calf.
What I learned
Preliminary Results
Calf Growth days 1 to 42
Treatment 1 1.13 lbs/day
Treatment 2 1.12 lbs/day
Treatment 3 1.11 lbs/day
Treatment 4 1.12 lbs/day
Interpretation of Results
•Calf growth was not affected by milk replacers fed
•Calves remained healthy throughout
•Final results will be analyzed statistically and information disseminated
