MAKING ROTATIONAL GRAZING WORK The concept of intensive pasture management through frequent rotations in a pasture has become an important management practice in beef production. This is particularly true for cow calf herds since it has been shown that this type of pasture manage ment will help reduce the need for stored feed, will improve the nutri tional value of a pasture, and will help reduce feed costs for the cow herd. It is, however, dependent on careful planning and management THE CONSERVATIONIST.

The basic concept of “intensive grazing” is that the cattle will graze all of the available forage in a given area in a short period of time before being moved to new stand ing fordge. Complete grazing and timely movement are essential to success. The complete removal of growth inhibits selective grazing. There will be no competitive advantage of one plant compared to another, thus, more desirable species like grasses and legumes will not have to compete with weeds and undesirable growth. Secondly, timely movement See The Dependable Great Plains Dealers Listed Below: will allow for an appropriate “rest periocT lo allow regrowthpflhc desirable forage. Most Pennsylva nia pastures are primarily cool season grasses ■— orchardgrass, bromc, bluegrass, fescue, etc. These forages also will respond well to rotational management, particularly if they also contain some legumes. However, they also present some distinct management problems since they have varying rates of growth during a given grazing season (maximized in spring and fall). How does the manager capture (he growth of these plants? The first method is through variable stocking rates. Many producers want to maintain the same stocking rate on a pasture for a season. This implies a given rate may be too low during periods of fast growth, or be too high during slow growth such as mid-summer for cool sea son grasses. By doubling or tri pling stocking rate in May and ear ly June, the cattle are able to harvest the grass at an optimum feed value. When there are not enough cattle and the grass “gets drives for transport. Lost Creek Implement, Inc.

Spring and early summerrest periods for most cool season grasses can be reduced to 12-IS days in many cases. This is about 1 /] to 54 of what the acreage rest period would be for the sea son. Therefore, up to one-half of the pasture can be harvested mechanically. The regrowth is returned to pasture when growth slows down in mid-summer. Third, use variable pasture spe cies. Cool season grasses are poor ly adapted to mid-summer and late fall grazing. Incorporation of spe cies that are more adaptable at these periods can help extend the grazing season. For mid-summer grazing, warm-season grasses and summer annuals can be used as Stouffer Brothers, Inc. 1066 Lincoln Way West Chambersburg, PA 17201 717-263-8424 Lehigh Ag Equipment, Inc. 6670 Ruppsville Road Allentown, PA 18106 215-398-2553 Lancaster Farming, Saturday, May 7, 1994-C3 part of the pasture. Alfalfa also works well in a pas ture system if it properly managed. Bloat can be prevented and the alfalfa stand can be retained for several years with proper grazing management. Two alternatives for fall grazing include brassicas and stockpiled grasses. Good fertility and seeding are necessary for brassicas to do well, but they can certainly contri bute to extended fall grazing. Fescue may be the best choice for stockpiling. New varieties of endophyte-free fescue have had excellent success, and can be grazed well into winter months.
