In the fruit and dairy districts the pressing work ceases in September; in the grain-raising sections it is October before the farm-horse gets relief. If fall or winter colts are to be raised, it is evident that the foals should not appear until October or November in the former case, and November and December in the latter, unless there are enough animals on the farm to permit of diminishing the work of those which are in foal. However, circumstances will to a great extent govern this and other details. Wherever the fall work will permit, the time of breeding might well be advanced two or three months; provided, however, the foal does not appear when flies are cruelly annoying.
The female is not as likely to be amorous in the fall and winter, as in the spring. Usually, she is rather thin in flesh after the summer's work. If so, the task of securing the desired results will be the easier. By increasing the food, especially the grain ration, by giving regular but somewhat moderate exercise, and by double or single blanketing, conditions will be produced similar to those which prevail in the spring. Meantime the bowels should be kept free from constipation by feeding moderate amounts of succulent foods.
It is often asserted that fall colts do not shed their hair as freely and as perfectly as do spring colts. It is doubtful whether this is so.
Colts usually shed their incisor teeth about three months in advance of their third, fourth and fifth birthdays. Fall colts shed their teeth when grass is yet abundant; spring colts when on dry, winter food. Dentition proceeds more satisfactorily when the animals are at grass than when fed on dry food.
