hernias
cleft palate
atresia ani
supernumerary teats
how can you measure colostrum quality?
immunoassay
colostrometer
brix refractometer
what is the goal for colostrum quality?
50 g/L IgG
total >150 g/calf
how much colostrum should be fed at first feeding?
3-4L
10% birth weight
when should colostrum be fed?
within 1-2 hours of birth
when should you feed fresh colostrum?
within an hour or refrigerate

as proxy for IgG
better for monitoring colostrum program than individuals
how much milk should calves get in the first three days?
2-3 quarts twice daily
why should you avoid feeding excessive forage until weaning?

vigorous rubbing of muzzle/head

when should you sample calves for serum total solids?
1-7 days of age
what is increased time with dam good for?
maternal bonding/oxytocin release
decreased labor input
public perception
why is immediate separation from dam good?
minimized pathogen exposure
uniform colostrum administration
decreases calving facilities requirement
