Happy Farms multi-variate regression models

[Guest guest]

Dear John,

 

The records I have kept over the years have shown the following averages:-

 

Daily milk yield - 7.26 litres per day

 

Length of lactation - 3.47 years

 

The average lactation could be slightly longer on average. We dried off one

cow after 5 years because we thought she was pregnant when she wasn't. She

could have gone on for another year which would have made a slight increase

in the overall average.

 

Sometimes a cow got pregnant without permission and thus she had a second

calf in the time she should have been still on her first lactation.

 

I have attatched the excel document for your information. Hope you can get

it.
