Irish Grove Farms consists of 205 acres. Depending upon the year, anywhere from 45 to 90 acres is utilized for rotational grazing, and the rest of the land is used for hay and/or grain production. Our intention is for all of this land to be in a grass-based system, but occasionally we grow a grain if we need to break the alfalfa cycle before replanting. Our grain crops are conventionally-managed, but 100% of our hay and rotational grazing ground is organically-managed.
Murray Grey Cattle and Rotational Grazing
In Irish Grove, we raise primarily Murray Grey beef cattle, a breed that is ideal for grassfed beef production. You can learn more about Murray Grey cattle here. We began with the purchase of 4 herd mothers in 2007 and have since grown to our current herd size of 35 cow-calf pairs (a mother cow and her calf is called a cow-calf pair), 20-30 yearling and full-size heifers and steers, and one bull. The cattle are rotated through organically-managed pastures in the summer months and are fed organically-grown hay in the winter. They receive no extra grain, hormones or preventative antibiotics*. We do supply a free-choice organic salt and mineral supplement that is custom made for our farm. The cows absolutely love this mineral and I have to admit it smells delicious.
In order to fatten our cattle on only grass, we practice rotational grazing, a technique which has been proven to increase forage production and improve the cattle’s access to high-quality pasture. Instead of letting the cows out into the whole field at once, we divide the field into smaller-sized paddocks and let the cattle into one paddock at a time. When they have sufficiently eaten the grass and alfalfa in this paddock, we move them into the next paddock and fence them out of the space they were just in. Each paddock is given a 30-day rest period before the cows are allowed to graze it again. Rotational grazing results in a field of large strips of grass at varying degrees of height and growth stage. This is the tell-tale sign of rotational grazing and is what you’d see if you drove by our grazing fields.
Traditional grazing gives cows access to the whole field at all times. While any grazing is better than no grazing, cows in a traditional grazing system will return to eat their favorite forage over and over again, ultimately stressing the plant until it dies. This is why most permanent pastures are filled with weeds; cows don’t eat the weeds, the weeds thrive and multiply, the weeds ultimately take over the field. We have one 5-acre pasture that illustrates this perfectly. We call this our “sacrifice” pasture and it’s where we put the cows when it’s too rainy and muddy to let them out into the grazing fields. This pasture is full of weeds, mostly thistle. By contrast, our rotationally-grazed fields have very few weeds except in the areas with heavy hoof traffic (near walking lanes and water tanks).
Laying Hens and Pastured Eggs
We raise about 50-100 laying hens each year and sell the eggs out of a fridge on our farm. The hens have daily access to a 2-acre field in which they are free to roam about, scratch to their delight and eat all the bugs they can find. Some chickens are more resourceful than others and so there are always a few that also roam around our yard and scratch out the mulch and soil in my flower beds (much to my chagrin). The hens’ diet is supplemented with a mixture of organic, homegrown ground corn, a purchased protein supplement and an organic salt/mineral combo. This mixture of exercise, grain, bugs and grass has resulted in what many, many people have told me are the best pastured eggs they have ever eaten.
