Heifers are the foundation of a dairy enterprise and replacements represent a significant investment. Information about raising replacement heifers on pasture is becoming more available as producers begin to adopt grass-based systems to alleviate energy costs associated with raising feed crops. For general information on raising heifers, refer to Cooperative Extension Service materials such as Raising Dairy Replacements or Agricultural Alternatives: Dairy Heifer Production, as referenced in the Online resources section.
Traditionally, dairy farmers have raised their own heifers, but custom raising of heifers is now becoming an enterprise in its own right. This can be an opportunity for supplemental income or a farm's main operation.
Raising cattle on pasture necessitates management decisions about grazing. Controlled grazing or management-intensive rotational grazing (MIG) of pastures can increase animal production and maintain resilient, diverse and nutritious pastures. Controlled grazing involves grazing and then resting several pastures in sequence. The rest periods allow plants to recover before they are grazed again. Although an intensive system has initial costs of electric fencing and watering investments, as well as increased management, many farmers report better profitability. Please refer to the Related ATTRA Publications for more information.
When planning a feed supplement program for pastured heifers, first determine the type and amount of forage the animal is eating, and then consider the nutritive content of the forage. Most cool-season grass-legume pastures provide more crude protein than is needed by the animal. In this case, a small amount of grain or bypass protein will stimulate gain. Native warm-season grasses and some legumes, such as birdsfoot trefoil, tend to be less soluble in the rumen and have a higher bypass protein availability. Producers can aim for the same heifer growth rates on pasture that are possible with confinement feeding of grain.
University of Minnesota researchers have documented gains and costs of raising dairy heifers in a feedlot versus raising them on pasture. In their study, the feedlot heifers had an average daily gain (ADG) of 2 pounds per head while the pasture heifers had an ADG of 2.04, with a total cost per head per day of $1.52 versus $0.95 respectively. The study, Tale of Two Heifer-raising Systems: Feedlot and management intensive grazing go head to head by Margot Rudstrom, is available online, and is referenced below in the Online resources section.
Local and state Cooperative Extension Service or Natural Resources Conservation Service (NRCS) personnel may have information on rotational grazing and grass dairying and can help choose forage species and varieties that work best for a producer in a grazing program. In addition, The Stockman Grass Farmer is a magazine "dedicated to profit from grassland agriculture" and has many articles dealing with grazing and sponsors workshops on grass management and seasonal dairying. Refer to the section called The Grass Farmer's Bookshelf in every issue of The Stockman Grass Farmer for useful books about forages and forage management. The magazine's editor, Allan Nation, recommends contract raising of heifers as a high-value enterprise particularly well-suited for small acreages.

It is increasingly common for heifers to be raised by contract on specialty farms. Hiring out the raising of replacement heifers is advantageous to a milk producer for at least two reasons. First, it saves labor on the dairy farm and second, it frees all the forage or other feed to be utilized by milk-producing animals. However, mingling heifers from several different farms is a concern for health reasons.
Custom raising of heifers is not recommended as an enterprise for beginning farmers because of the level of knowledge and experience needed to manage young animals. Grazing expertise is useful since pasture and grazing management are key to enterprise sustainability and profitability. Finding heifers to raise may be difficult at first, but a good reputation and track record will be assets in securing animals. Breeding expertise may also be important depending on contractual obligations.
Tom Wrchota in Wisconsin received a Sustainable Agriculture Research and Education (SARE) producer grant to custom graze heifers and summarized his results in a report called Developing Dairy Heifers on Pasture. According to the SARE report, "the most surprising aspect about the development and successful implementation of a seasonal custom heifer grazing program was: the grant program started with very modest amounts of capital, almost no experience and a limited cash/no debt strategy." The SARE report can be accessed online.
The costs associated with a custom heifer raising enterprise include labor, feed, facilities and fencing and veterinary costs. Feed costs and labor costs are usually the largest costs to a custom grazier. High-quality pasture and good grazing management can help reduce these costs and ensure a profitable, sustainable enterprise.
The Economics of Heifer Contracting, by Robert Moore, Joseph Beiler and Gary Schnitkey of The Ohio State University, was developed to assist producers in estimating costs and charging to cover costs from a custom heifer raising enterprise, and can be accessed online.
The use of pasture and grazing management to raise dairy heifers is becoming more prominent in the industry, and the following online resources will assist the interested producer in planning and managing this risky but often rewarding enterprise.

Based on the experiences of the limited number of cooperators in the project, this is a high-risk operation with minimal financial returns to the farmer. Problems encountered were the source and price of quality dairy heifers in the spring, what type of arrangement the producer could make to market the animals at the end of the pasture growing season and the variability of pasture production in southwest Iowa.
