and their roles on the farm
Many, many farms keep cows for their meat and/or milk production. And they are certainly excellent producers of both. However, our cows have a variety of jobs on the farm, jobs that none of our other animals can do quite as well as they can. Here's a partial list of our cows' work load:
* Land building. Our farm sits on the side of a hill, and the topography is very uneven. We hardly have a flat spot on the property. So our cows are land-builders. We accomplish this by housing the cows in a small yards and feed them their hay on the ground. The combination of waste hay, manure and bedding can build up very quickly, and will fill in any low spots we happen to have in that yard. When their current yard ground level has been sufficiently built up, we move them to another yard and the cycle begins again.
* Animal feed. We are not yet licensed for retail milk sales, but our cows' milk is used in a wide variety of ways. We save colostrum after each calf's birth which can be used as substitute colostrum for youngsters of other species. Our pigs also thrive on cow's milk as a valuable source of calories, protein and other nutrients that are costly to provide from other sources.
* Soil innoculation. Soils are living, breathing collections of macro- and micro-organisms. When starting with bare or abused ground, sometimes that ground needs to be innoculated with new bacterial cultures. Cow manure, well managed, can give soils a potent boost of both microorganism populations as well as organic matter. Combine that with the right ratio of carbon-rich bedding, and cows can lay down a sheet of living compost wherever they go. You can't buy that kind of soil fertility, not at any cost.
* Heat production. Cattle are basically walking compost piles. An individual cow's rumen volume is considerable, and the heat she puts out is also considerable. In cool or cold climates like we have, that heat source can make a nice difference in winter housing conditions. If other animals or plants are housed in connected housing, they can benefit from that heat source indirectly.
We are actively exploring alternatives to conventional, petroleum-driven power sources on the farm. Oxen-drawn implements, treadmills, and various harnessing methods can provide tremendous, practical, cost-effective power to farming, logging, milling and household power needs. Our
