Well reared when calves, neither stinted , nor over-fed, allowed the exercise which young growing animals require, and put to the bull when about two years old, there is seldom difficulty with their breed- ing. Where any delay or difficulty occurs, change the feeding and management of the heifer, aud try another bull. If oestrum is irregular, or more fretjueut than eighteen days, service should not be allowed. One service is sufficient, and the cow should thereafter be kept quietly by herself for at least one day. The average 2ieriod of gesta- tion is 284 days; small cows, heifers with their first calf, and old animals usually go a day or two less; bulls are carried a day or two longer than cow-calves. Abortion, or sUpphig—the most serious mishap affecting cows during gestation—results from long fatiguing travel, the shaking of a railway journey, the galloping and excitement caused by the sudden appearance of foxhounds, laborious toiling through a yard full of wet manure or a muddy lane, slipping or getting crushed in an awkward stall.
