Grazing at Grassland Dairy

Grazing at Grassland Dairy

The Tillotsons (Brent, Polly, and their twin sons) own and operate a certified organic dairy farm in Pavilion, NY, Genesee County. Two thousand nine was the first full year of production. Today, between 100 and 110 Jersey cows are milked in a conventional swing parlor, and the farm has about 90 replacement animals. During the grazing season, dry cows and bred heifers obtain 100 percent of their forage needs from pasture, while milking cows obtain forage needs from pasture and a mixed ration. Milking cows are fed grain, while dry cows receive minerals. Two hundred sixty acres of rented tillable land meet the forage needs of the herd. No corn silage is grown. All other required feeds are purchased -- corn grain for the milking herd, calf grains, and a mineral batch. Brent notes that excellent forages, in the form of grown grasses consumed as pasture or as stored baleage, are key to achieving desired results. Rye grass is the primary forage crop, while clovers and orchard grass share the balance.  "Clipping pastures 2 to 3 times a year to manage weed pressures," and "Not grazing pastures too tall, because they tend to get knocked down" are mentioned as important practices in Grassland Dairy's overall approach to producing quality forages.

Cows currently produce about 45 to 50 pounds of milk per day. Milk receipts are enhanced beyond a base organic price when butterfat, protein, and quality factors exceed certain levels. The herd currently averages 4.9 percent butterfat, 3.75 percent protein, and somatic cell counts of 120,000.

The decision to produce certified organic milk was driven by Brent's desire for

  • a farm that met the family's financial goals, and
  • a farm that did not require "too many employees, and too much capital investment."

Milk price volatility in the conventional milk market and the desire to avoid the volatility also affected the decision. Regarding Brent's decision to produce certified organic milk, the article states "...he's relieved - and thankful - he decided to go organic."

Current Practices Result from Challenges Faced

Weather Uncertainties
Brent cites adjusting to weather uncertainties, for example, the dry summer conditions of 2009 and the negative effects on grass growth, as a challenge. In 2009, the first full year of organic production, Brent found himself having to rethink the amount of pasture needed. The decision was to fence off all but 60 of the 260 acres, including extending waterers, to accomplish production goals. Where cows were expected to travel a half mile or less to pastures, the expanded pasture area meant that cows now travelled up to three quarters of a mile to a mile to access pastures. Currently, 200 acres are fenced. Twenty 350 feet by 400 feet paddocks are for rotational grazing of dairy cows, while about 40 additional acres are for heifers. The balance is fenced, but not set up for paddocks. The current system provides needed flexibility during periods of poor pastures so that adequate forages are available during the season to meet production goals.Brent emphasizes the importance of providing plenty of water. Water is available at every opening, about every 300 feet. "Animals aren't crowding around waterers when they arrive at a paddock." 

Fly Pressures
Fly pressures while cows are on pasture, especially dry cows, and the potential negative consequences for herd health present challenges within the certified organic milk production framework. Regarding fly management, Brent emphasizes the role of allowable vaccinations -"Vaccination protocols - part of a proactive, preventive approach - are high on our list of practices."

Record Keeping
Record keeping associated with organic certification, including detailed records for animal, paddock movements by day, present challenges. Polly, the farm business'  Financial Manager, and Brent do their best to understand the requirements. They work hard to keep records up to date, and try to stay informed about changes, for example, USDA's new organic pasture rule that was issued in early 2010. Their efforts are paying off -- Polly mentions that based upon certifiers' comments, they are doing a good job.

The Future
In the near future, the Tillotsons look to achieve and maintain a milking herd of about 120 cows maximum. A new heifer, dry cow barn with capacity for 100 animals is also a key piece for keeping the farm viable in terms of obtaining desired results in the future. Important financial goals include reducing debt. Brent will always be seeking opportunities to maintain and, or improve pastures via laneway and watering system maintenance and improvements, and via new seedings - all ryegrass is the goal.

A Final Thought
The Tillotson's herd of Jersey cows did not have to make the often difficult transition from conventional confinement housing to a pasture based system. Heifers were started on pasture well prior to the 2008 start date for the dairy, and all animals now entering the milking herd have been on pasture. However, Brent does recognize that in other situations animals need to be taken away from the bunk, learning to eat from pasture. Here, Brent shared the view of intensive grazing expert Don Wild, "Go out to lunch for a few days and let them bellow."

Grassland Dairy's story will also appear in Cornell University Cooperative Extension's Dairy Farm Business Summary Extension Bulletin on Intensive Grazing. To order call Linda Putnam at (607) 255-8429 and ask for E.B. 2010-10.

Dairy Comp 305 for Spanish Speakers

April 19, 2023

This program was rescheduled from March 30th.

This workshop is for employees, supervisors or managers whose first language is Spanish and whose job entails using DC305 on a daily basis.  The objective is for attendees to improve their understanding of the "language" of DC305 as well as the whys behind consistent data entry.  Since DC305 is specific to each farm, the workshop will focus on general application and deeper understanding of how data is used on dairy farms.
