if starter has good texture, probably not (maybe if its a pelleted starter)
What is the thermoneutral zone for newborn calves and 1 month old calves?
newborn 50-78 degrees
1 month old 32-73 degrees
What usually happens b/w 35-70 days of age? (5)
diarrhea incidence should be decreasing, respiratory disease may be on the rise, stater intake should be increasing, preventative vaccinations, weaning when intake is suitable for maintenance and growth (~2.2lb/day)
What challenges arise during 6-10 weeks of life? (3)
respiratory disease risk period, transition to group housing, transition from milk to grain/forage
What is the ideal bodyweight at first breeding?
55% of mature weight
What is the ideal body weight at first calving?
82% of mature weight
What are weaning strategies? (3)
reduce volume of liquid feed, reduce number of feedings to once per day, dilute liquid feed with additional water (if you have resources, time for this)
