Estrus, or heat, is the period in which the doe will stand and allow the buck to breed her. This phase of the reproductive cycle may last between 12 to 36 hours. The period from one heat cycle to the next is referred to as the estrous cycle. In goats, the estrous cycle occurs every 18 to 24 days, or 21 days on average.
Rutabagas are a cross between cabbage and turnip. Turnips are easy to grow if sown in the proper season. They mature in two months and may be planted either in the spring, late summer or fall for roots or greens. The spring crop is planted for early summer use. The fall crop, which is usually larger and of higher quality, is often stored for winter use.
