Hi Guys

could you please help me to find out the solution to this question

I would like to know how to find the effect of environmental factors by using the individual parameter estimates from this code above.

Note: the environmental factors are e.g (parity, calving month ...... .)

in this case what the next step I might do to get this answer.

if you looking for more information about my study please let me know

kind regards

Ibrahim
