Here are the preliminary results (June 3), as reported by Michael Schmidt:
The weight of the two calves was basically equal at the beginning of the feeding trial.
At the end the raw milk calf weight 200 kg and the pasteurized milk calf weight 115 kg.
They gained weight almost equally for about 8 weeks and then the pasteurized milk calf started falling back.
A significant difference during the 4 month trial was always the different smell and the consistency of the manure. The raw milk calf had mostly a well formed manure and normal smell you would expect. Contrary to that the manure of the pasteurized calf was runny and the color mostly grey or almost white during the feeding trial.
We did not treat either of these calves for any condition. We would have if there would have been a life threatening situation.
The hair on the raw milk calf was shiny and solid on the pasteurized calf dull and easily pulled out.
The alertness in the two calves was a major difference: the pasteurized calf seemed very uninterested with a clear lack of movement.
After nearly 5 months we could see that the pasteurized calf would have had difficulty to survive without medication and supplements.
Below are some of the pictures to show the obvious visual differences.
A tale of two stomachs -- in the cart raw milk stomach with solid contents, and on the floor the stomach from the calf which was fed on pasteurised milk, with very bad smelling runny contents.
