Had a calf the was born at 4:00 this morning was fed 2 quarts of colostrum at 5:00 then tried again at 11:00 and it wouldn't suck so i tube it I noticed it's gums was red right at the base of its teeth I know that means its not got enough colostrum or not soon enough I would think 4 quarts in 7 hours would be fine but its gums are almost completely red now
