Management intensive rotational grazing’s sense…and dollars (Research Brief #19)
What we’re seeing is a little extra money from grazing while putting in a little less labor. — Gary Frank
How can dairy farmers make their time worth more? A study sponsored by the Center for Integrated Agricultural Systems (CIAS) suggests that compared to confinement systems, management intensive grazing can turn work hours into higher profits by reducing machine, production, and feed costs. The researchers drew these conclusions by calculating the economics of five dairy simulations, ranging from a confinement-based year-round scenario, to a pasture-based, seasonal system.
Bimal RajBhandary, a CIAS agricultural economist, Gary Frank, a farm management specialist with the UW-Madison Department of Agricultural Economics, Larry Tranel, Iowa County’s UW Extension agriculture/agri-business agent, and Rick Klemme of CIAS wanted to explore how farm profits might change as farmers switch from confinement to grazing systems and reduce their investments in field equipment.
Approximately 2,500 Wisconsin farmers have adopted some form of management intensive grazing for environmental, economic, philosophical, and other reasons. The research team wanted to know whether conventional farmers could use pasture-based dairying to increase their profits without huge investments.
“A lot of dairy farmers are not generating as much income for their families as they would like. They are asking, ‘How can I take what I have and use it a little differently, so that I can make more money for my family?'” said Frank. The study addressed such questions by looking at how grazing may influence farm profits and affect the return a farmer can expect from an hour of labor.
Setting up the scenarios
The research team simulated five dairy systems based on a 50-cow, 60-cow, or 70-cow, 150-acre farm, using a confinement system as a basis of comparison. In constructing the scenarios, the researchers wanted to examine the economic factors that influence farm profits and returns to labor in conventional systems compared to pasture-based methods that incorporate seasonal calving or reduced investments in field machinery.
The five scenarios are based on three production levels (15,000, 18,000, and 21,000 lbs./cow/year.). Tables 1-4 summarize key points for the scenarios.
Based on these models, the researchers calculated expected income, expenses, and labor for each system. They based these values on estimated labor, crop, and machine costs calculated by farmers, county agents, and farm researchers, instead of actual average values from a large number of grazers.
Frank said the available data from farmers who have switched to grazing is limited. “We made the best effort to consult farmers and agents and come up with realistic numbers,” he said.
Calculating profits and returns to labor
The researchers calculated expected production values, profits, and returns to labor for each dairy scenario. Tables 1-5 shows these values for production levels of 15,000 and 18,000 lbs./cow/year.
Based on their data, the team concluded the following:
Pasture-based scenarios (both year-round and seasonal) showed higher profits compared to year-round confinement systems. However, to show a net profit, pasture-based systems need production levels near those of confinement systems.
At a production level of 15,000 pounds, none of the scenarios with full investment in machinery showed a net profit in their study. This is mainly due to relatively high overhead and operating costs.
However, once production levels reached 18,000, the pasture-based, year-round scenario showed a $3,867 higher profit compared to confinement systems. The increased profit is due to lower operating and feed costs. The seasonal scenario showed a $2,880 higher profit over a confinement system, mainly because of a 15 percent reduction in labor costs and a six percent drop in overhead costs. This is despite the fact that in the seasonal system milk production was reduced by 10 percent to reflect a shorter lactation period.
At a 21,000 pound production level, profits are still higher for the pasture-based scenarios compared to confinement systems.
“What we’re seeing is a little extra money from grazing while putting in a little less labor,” Frank says. “That means you may have a little time left over to go watch your kids play softball.”
Profits from the pasture-based systems increased even more when investments in field machinery were replaced with custom hired help.
The study predicted a profit advantage of about $9,400 over confinement systems for a pasture-based, year-round system that got rid of field equipment (at all three production levels). This profit advantage was slightly less for seasonal systems that reduced machine investments. These had profits of $8,583 and $7,788 over confinement systems for production levels of 18,000 and 21,000, respectively. The increased profits flow from a 6 to 8 percent decrease in overhead costs.
“This shows that you don’t really get profitable in rotational grazing until you bite the bullet and get rid of much of your equipment,” says Frank. Yet reducing equipment requires a commitment to grazing. “You can never buy back equipment for less than you sold it for,” he says.
Pasture-based systems (both seasonal and year-round) had generally higher returns to labor hour than confinement systems. Pasture-based seasonal systems had the highest returns to labor hour of all the scenarios.
These figures suggest that for a given hour of labor, a pasture-based system can yield a higher returns than a confinement system. For example, at an 18,000-lb. production level with full investment in machinery, the pasture-based systems showed a return of $9.66 per hour for a year-round system and $9.87 for a seasonal system, whereas the confinement scenario showed a return of only $8.95 per hour.
The returns to labor from pasture-based systems were even higher when investments in field equipment were reduced. Year-round systems were $10.73 per hour, whereas seasonal systems were the highest at $11.19. Based on these data, pasture-based systems, compared to confinement methods, may offer farmers a better profit return for their labor.
That means by switching to grazing, a farmer may get more by working less.
Is this possible?
The researchers caution farmers that the study is based on simulated dairy models rather than on numbers from actual farms. “People should realize that grazing won’t turn a poor manager into a good one, but it does hold promise for well-managed farms to increase their total income while reducing their workload slightly,” Frank said.
The study analyzes only one seasonal grazing system, a scenario that assumes a farmer has some grazing experience. In the future, the research team will look at modified seasonal systems that assume a portion of the dairy herd produces year-round. Frank said other studies will examine how increased herd size, low-cost milking parlors, and reduced building investments may affect seasonal grazing profits.
