Student Life. Harvard University has around 22,000 students across the College, graduate, and professional schools located in Cambridge and Boston. When people refer to Harvard students, often they mean the subset of roughly 6,700 students who attend Harvard College. Students arrive every year in late August.
Heifer. Heifer is the female cow who has passed the calf stage but has not reached the cow stage. Usually, the calf stage ends when the age reaches 10 months from birth. A female will be called a cow when she becomes a mother after reaching the reproductive viability. The heifer is the middle stage of the calf and cow.
At least an 85% weaning rate should be anticipated. At an age of 15 to 16 months, heifers have a +65% chance of breeding if their body weight exceeds about 400 pounds or they are at least 70% of their expected adult weight. Cows generally bare only one calf annually, and the sex ratio is close to 50-50.
